Aruto Hiden (飛電或人, Hiden Aruto) is the main protagonist of Kamen Rider Zero-One. He is a 22-year-old former comedian and the current CEO of Hiden Intelligence who fights as Kamen Rider Zero-One (仮面ライダーゼロワン, Kamen Raidā Zerowan) alongside his Humagear companion Izu to pursue his dreams of making others smile. After his loss in the Workplace Competition, his drive to continue fighting against the Ark and unite both humanity and Humagear inspired him to create a new company and fight as Kamen Rider Zero-Two (仮面ライダーゼロツー, Kamen Raidā Zerotsū). However, he would eventually lose his faith and be consumed by the desire for revenge, temporarily becoming Kamen Rider Ark-One (仮面ライダーアークワン, Kamen Raidā Ākuwan).

Due to manipulations of the timeline by the Time Jacker Finis, Aruto lost the Zero-One Driver after losing to Another Zero-One, which resulted in him temporarily resorting to usage of a Forceriser to transform into Kamen Rider ZeroZero-One (仮面ライダー００１［ゼロゼロワン］, Kamen Raidā Zerozerowan).

Biography

Early Life

Aruto Hiden was born on May 1, 1997 to his parents Soreo Hiden and Yoshino Hiden, and to his grandfather Korenosuke Hiden, the CEO of Hiden Intelligence at the time. When Aruto was only two months old, his parents passed away in an accident, so his grandfather built a Humagear resembling his father to take Soreo's place as a parent and as an emotional support.

Young Aruto mourning his father's shutdown during the Daybreak Town Accident.

One day, Soreo asked Aruto what his dream was, and he responded that he wanted his father to be happy. Wanting to share that happiness with his son, Soreo began creating the Hiden Zero-One Driver, which ultimately served to prevent a worldwide catastrophe that would have resulted in the Humagears taking over the world. ^{[Kamen Rider: Reiwa The First Generation]}

Aruto and Soreo were present on the day of the Daybreak Town Accident, where they were enjoying a family outing where young Aruto spent most of his time engaging in comedic antics. When chaos erupted from the Hiden Intelligence building, Soreo shielded Aruto from one of the explosions, but was grievously damaged in the process. In his final moments, Soreo encourages Aruto to continue pursuing his dream before his systems shutdown completely, leaving the young boy to grieve.

In his adulthood, Aruto pursued a career in comedy, doing street performances with a friend as a duo. However, the friend left after he got tired of Aruto's jokes.

Becoming Zero-One

At the age of 22, Aruto is continuously struggling to hold his career as a solo comedian. After getting fired from his job at a theme park, Aruto was met at the park entrance by Izu, a secretary-type Humagear who escorted him to Hiden Intelligence headquarters to discuss the wills of his late grandfather, which revealed that an imminent crisis involving the Humagears will happen again, and the only way to combat against them is the Hiden Zero-One Driver, to be used exclusively by the succeeding president, whom his grandfather had named Aruto as. Although the entire board of directors were enraged by this sudden development, Aruto quickly turns down the role and excuses himself.

"Zero-One, that's my name!"

―Kamen Rider Zero-One introduces himself to the Berotha Magia^[src]

As Aruto goes back to the theme park in an attempt to beg for his job back, the Berotha Magia attacks the park, and Aruto attempts to stop him but is beaten senseless. After becoming enraged from the Magia saying that human dreams were meaningless, Aruto re-stood his ground and asked the just-arrived Izu for the Zero-One Driver. Aruto's mind was then uplinked into the communications satellite Zea, where his mind processing speeds were enhanced to the point where he learns the entire Zero-One tutorial in five seconds. Aruto transforms into Zero-One for the first time and destroys the Trilobite Magias as well as the Berotha Magia. After his first battle, Izu reveals that by accepting the Zero-One Driver, Aruto had also accepted being president. Originally being reluctant to do so, he was re-inspired after seeing the park manager's gratefulness for Zero-One. ^{[I am the President and a Kamen Rider]}

As CEO of Hiden Intelligence

After Aruto and Izu arrived in Hiden Intelligence HQ, he was guided by Izu after she introduced herself as Aruto's personal Humagear assistant. Aruto was halted, but then greeted by a Security Guard-Type Humagear.

Izu takes an excited Aruto to the CEO's office and give him his first task as the new CEO: to welcome the representatives of A.I.M.S., a special government force dedicated to subduing A.Is. The representatives reveal themselves as Yua Yaiba, head of R&D, and Isamu Fuwa, the force's captain. Isamu suddenly accuses Hiden Intelligence of covering the Humagear rampage at the amusement park, but Aruto denies all of his accusations with help from Izu.

To ease tension, Aruto tries to do his signature jokes, but no one reacts (as usual). However, Isamu is seemingly shaken with anger. Their conversation is cut short, however, when an intruder is detected inside the building.

Okureru, now the Kuehne Magia, is attacking Hiden Intelligence, A.I.M.S. and nearby civilians, but were protected by Security Guard-Type Humagear. Aruto attempted to transform into Zero-One, but the Kuehne Magia escaped using his wings.

Aruto was taken by Isamu to the rooftop, and the latter revealed his hatred towards Humagears after the Daybreak Town Accident, the same day that Aruto's father Humagear, Soreo Hiden, was destroyed after protecting him from an explosion. Later, Aruto searches for the security Humagear that protected the civilians before. Upon learning his name as Mamoru, Aruto tells him to search for maintenance since his body was damaged by Kuehne Magia, unaware of the fact that someone was watching them, Jin.

During the second attack from the Kuehne Magia, Aruto saw Jin standing with the corrupted Mamoru who transformed into the Ekal Magia and was ordered by Jin to kill Aruto. After he remembered Izu's words during the Ekal Magia's attack that a corrupted Humagear cannot be restored to normal, Aruto then transforms into Zero-One and overwhelms the Ekal Magia, but the latter escapes by using a hacked motorcycle. Izu then tells Aruto about the RisePhone's ability to summon the bike known as the Rise Hopper. After Zero-One scanned his RisePhone, a big replica of the RisePhone fell from Zea, and transformed into Rise Hopper. Using his new bike, Zero-One chases after the Magia outside. He successfully throws the Ekal Magia off from the bike, and they continue the fight in an empty dock.

Aruto then destroyed the Ekal Magia by using the Rising Kaban Strash, until he saw Isamu as Kamen Rider Vulcan from the hole made by Vulcan's Shooting Blast; they saw each other before Aruto somehow vanishes in the smoke.

The next day, Aruto, alongside Izu, introduces himself as the new CEO of Hiden Intelligence on the press conference and plays the recording from Izu about MetsubouJinrai.net, letting the press know about the existence of the terrorist organization. He also claims that Humagears are developed by Hiden Intelligence to realize humanity's dream while looking at Mamoru in a rebuilt body. A journalist then asked about Aruto's past job as a comedian. To demonstrate, Aruto performs one of his jokes, which confused the press while destroying the serious mood. A shaken Isamu tries hard not to laugh at Aruto's lame joke before leaving. Izu also tried to explain Aruto's jokes, much to his protest. ^{[Is AI The Enemy? The Ally?]}

Humagears Rampage Aftermath

Hiden Intelligence's reputation has gone down after the Humagear's massive rampage at the hospital, but was later involved with a drama television show with Enji Matsuda, an Actor-Type Humagear who was the star of the show alongside with Shinya Owada, a very well renowned actor. Aruto then convinced Jun Fukuzoe to participate in the show, as Jun agreed with the invitation to participate in the show, but with a frown.

When Aruto was filming the drama alongside with the other cast, Izu tells Aruto about MetsubouJinrai.net's attack with her pose and her hand sign, Aruto was shocked by Izu's words but instead surprised the crew with his reaction. Later, Aruto joins the battle after he was informed about Little Assassin and transforms into Kamen Rider Zero-One Rising Hopper to fight against Jin. As Aruto was trying to use the Attache Arrow to fight Jin, it was taken by Jin, but he later use his Freezing Bear form to finish off Jin before he escaped. ^{[I am an Actor, Shinya Owada]}

The Workplace Competition

^{[I am the Only President and Kamen Rider]}

Beginning of the Competition

^{[I am the Only President and Kamen Rider] [This is My Floristry]}

Hidden Revelation on Real Estate

Aruto and Izu are seen talking to Gai about the second round of the competition. Izu said that Hiden Intelligence is losing the competition at 0 to 1, and Aruto replied saying that they're not going to lose this time. Then, Gai announces that the second round will be a real estate. Yua then comes in to introduce Tatsumi Arayashiki. Izu finds Smile Sumida for Hiden Intelligence. Gai then explains the guidelines, and Aruto makes one of his signature jokes.

Aruto is seen at Smile Sumida's office, welcoming customers. After they arrive at the house that Smile chose to sell and took a tour, Aruto made another one of his signature jokes, and the customers happily bought the house.

Later, Aruto, Izu, and Smile are selling another house, but got interrupted by the Splashing Whale Raider, who was destroying the house. Aruto transforms into his Rising Hopper Form.^{[She is a Home-Selling Humagear] [That is 1000% the Best House]}

The Enraging Trial, Thouser's MetalCluster Progrisekey

^{[Objection! That Trial] [He Still Didn't Do It]}

Ark's Control and The Rise of MetalCluster Hopper

"You don't know what's going on, right? Even I don't know what's going on!"

―Aruto when Gai couldn't understand how the former could control MetalCluster Hopper^[src]

Aruto is unable to control his body whenever the MetalCluster Hopper is used. He continues a futile resistance Ark's malice and begs to stop controlling his body during the rampage of both Storming Penguin Raider and Ark Magia (Gaeru Type). He was finally forced out of transformation by Thouser's Thousand Break (while using the Amazing Caucasus Progrisekey's Power) and was knocked unconscious for three days. He was later rushed into the hospital and attended by Dr. Omigoto and a Nurse-Type Humagear along with Izu.

Aruto then regains consciousness as Omigoto explains how broken his body is and that he would need rest from using the MetalCluster Hopper Progrisekey. Then, Marriage Match walks in with flowers for Aruto. Aruto suggest that he and Match should apologize to Chiharu Ebii, but Match told him that he doesn't need to be worried as he reveal that Teruo Nikaido and Ebii are a Best Match when he first met Nikaido. Match also explains to Aruto that when he become a Magia, it was so that the immediate danger would bring Teruo Nikaido and Ebii together.

Later, Aruto was informed by Omigoto that Enji Matsuda had gone berserk and was forced to transform into Arsino Magia after he was caught by Gai Amatsu after Enji infiltrated ZAIA Japan and was told by Omigoto to go after Thouser and Enji. After Aruto saw Thouser and Enji, Aruto then immediately transformed into MetalCluster Hopper but was stopped by Izu who gave him Progrise Hopper Blade to transfer Aruto's mind back into Zea.

Aruto then fights against Thouser as Aruto used Progrising Strash while Thouser tried to use the Arsino Magia as a shield. However, Aruto saved Enji from Zetsumeriser and Arsino Zetsumerisekey while he was told by Izu that Progrise Hopper Blade can restore Humagear back to their normal state. Aruto then thanks Izu and the Humagears and later defeated Thouser with the Ultimate Strash. ^{[I'm in Love With Your Intelligence!] [It's Our Turn]}

Creating HIDEN Manufacturing

After his position as CEO of Hiden Intelligence was taken by Gai Amatsu, he was forced to relinquish his Hiden Zero-One Driver due to ZAIA Enterprise Japan being declared as the winner of the Workplace Competition. However, since the rights of the Humagear and Zero-One technology belonged to Korenosuke Hiden, Aruto was authorized to use them when Jin helps him steal them back from Gai's office, with Izu creating a new company for him, HIDEN Manfufacturing.^{[After All, I am the President and a Kamen Rider]}

With his new company, he focused his efforts on recovering discarded Humagears using the Humagear Progrisekeys. He was first approached by the comic creator Ishizumi, asking him to restore his Humagear G-Pen Morifude. However, as he has not achieved Singularity yet, he was consistently failing to connect Zea to himself. This brought enough distraction for Jin to take him away from Aruto after a brief scuffle so he could be "free".

Apologizing to Ishizumi, he revealed to Aruto that working with G-Pen encouraged him to have a new dream: to help G-Pen become an independent comic artist with limitless boundaries. Upon hearing this, Aruto attempted to find G-Pen, only to find him cornered by ZAIA Japan. As he reveals Ishizumi's intentions to G-Pen, Yua questions his decision to let him run free, to which he responds that Humagears were not simply tools of humanity, stating that it was perfectly fine for Humagears to have dreams of their own. With that encouragement, G-Pen achieves Singularity, vowing to create an original comic of his own creation as Aruto encourages him to show the world his talent, unaware that Jin has been observing them the entire time. As they leave, Yua hesitates to shoot them, as she believes that Aruto was genuinely right in his words.

After returning G-Pen to Ishizumi, he heads back to his company, only to encounter Gai and his henchmen. Gai offers to pay Aruto "handsomely" in exchange for acquiring the Humagear data in his possession, but he declines, stating that Humagears will choose how to live their own lives from now on. Infuriated, Gai transforms into Thouser while Aruto holds them back as Zero-One MetalCluster Hopper. As Gai vows to crush Aruto's dream, Jin suddenly intervenes, revealing that Aruto's actions have taught him something: Humagears can never truly be free and reach Singularity without someone to guide them to pursue their own dreams. Therefore, he willingly entrusts the future of his kind and submits his allegiance to Aruto as they take down Thouser together. As Thouser retreats, he furiously swears revenge on Aruto, vowing to crush his company to the ground. Later that night, Aruto returns to his company just as Izu completes repairing another Humagear. Aruto chooses to reactivate the Humagear as Shesta, but Shesta instead transforms into Matsurida Z No. 5, who celebrates Aruto's success with Izu.^{[Take Off Toward Your Dream!]}

Humagear Status Restoration

Sometime later, Aruto employs Fuwa to be a bodyguard for HIDEN Manufacturing. He is then approached by Mr. Furusawa, the manager of a fashion magazine, who is desperate to have his Fashion Model-Type Humagear. Delmo returned to him in time for the Tokyo Fashion Collection event. Aruto manages to restore Delmo, who greets him with a hug, surprising Izu. The greeting was short-lived, as Gai sent ZAIA soldiers to destroy Delmo and Izu. Aruto and Fuwa prepare to drive them away, but Yua manages to take control of Fuwa by awakening Naki using the Assault Wolf Progrisekey. As the Naki-possessed Fuwa attempts to destroy Delmo and Izu as MetalCluster Hopper holds him back, Jin swoops in to intervene and incapacitates him swiftly. He then tells Aruto that he needs take Vulcan with him to release Naki out of his A.I. chip to which Aruto trustingly lets him do so.

During the preparation for the modeling, Aruto observed Delmo's progress and questions her for why she let the Humagear module to be kept visible towards watchers. Delmo claims the module to be her pride and a symbol that she is glad to exist as a Humagear and also showing her happiness by making a simulation of fan's shout of supporting, showing how far Delmo has become as a Humagear with singularity.

Gai noticed the restoration of Delmo. Allowing her to show up in fashion show in public broadcast will mean that the Humagears' image will be uprisen. Therefore, Gai proceeds to command Yua to destroy Delmo. As Delmo was in danger, Aruto came to rescue her, but her leg was damaged from the assault. With the return of Isamu and Naki, who were finally free from Gai's control, Aruto followed Izu's idea on replacing the position from Delmo, making Aruto's plan to restore the status of the Humagear in a successful result by becoming the model show alongside Izu. After the audience, Aruto announced Hiden Manufacturing and its goal for the Humagear restoration, being received well by the public.^{[My Pride! Runway Dream]}

Rise as Zero-Two

File:Aruto Hiden Transform into Zero-Two.jpg

Aruto's First Transformation into Kamen Rider Zero-Two

"Kamen Rider Zero-Two... that's my name!"

―Zero-Two introduces himself to Ark-Zero^[src]

After Aruto and Izu visited Zea for advice, they realized that Zero-One was no longer capable of updating. After several simulations regarding Ark-Zero's defeat of Aruto and his allies, Izu created the Zero-Two Driver alongside Aruto based on his sketches. Aruto later uses the Hiden Zero Two Driver to defeat Kamen Rider Ark-Zero.^{[Towards Mine And My Dream][Thou, Take Thine Neighbor's Hand!]}

Descent Into Darkness

Aruto ominously smiling at the Ark-One Progrisekey

"Horobi...you destroyed Izu. Doesn't your heart hurt? Have you felt any pain at all?!"
"SILENCE! I don't have such a thing! As long as there's malice in human heart, I will fight! That is Kamen Rider Horobi!"
"I'll never forgive you!"

―Aruto, driven by revenge for Izu's death, transforms into Kamen Rider Ark-One to fight Horobi^[src]

Due to Izu's murder by the hands of Horobi, Aruto fell into despair over the death of his longtime companion and was unable to cope. Suddenly, he was then approached by Azu (mimicking Izu), who told him about his own rising malice and offered him the Ark-One Progrisekey to become the incarnation of the Ark and get the revenge he now desperately craved. Aruto then smiled maliciously at the sight of the Progrisekey, realizing that the Ark and its power can help him avenge the now destroyed Izu. By taking the Progrisekey, the Ark's remains painfully merged with him, transforming into Kamen Rider Ark-One. Revealing his new power, Ark-One headed towards the battle that was taking place between the two A.I.M.S. Riders and Horobi, with his army of Magia.

After making a surprising thunderous entrance, Ark-One single-handily defeated each of the Magia army one-by-one, stopped Jin and Vulcan's attempted interference, and wiped out every combatant with the Perfect Conclusion: Learning 5, before going to destroy Horobi himself. However, Aruto couldn't handle the strain of his new power and was forced to cancel his transformation, revealing his identity as Ark-One to a shocked Isamu, Yua, Jin, and Horobi. After glaring at Horobi, he then exited the scene using smoke, and returned to Azu near the entrance of a building. Suddenly, Aruto began to break down in uncontrollable sadness due to now being the Ark itself, and glared at Azu after she attempted to comfort him.^{[As Long As There's Malice]}

"Why didn't you try taking our lives?"
"Just leave me alone already. This is a matter between me and Horobi."

―Gai questions why Aruto, as Ark-One, didn't kill the Riders confronting him

Sometime afterwards, Aruto, having already transformed into Ark-One, enters Daybreak Town on his own to find Horobi, but was confronted by Kamen Riders Vulcan, Valkyrie, and Thouser, who believed that Aruto was being possessed by the Ark. Annoyed by their interference, Ark-One defeats the three Riders with ease, even managing to destroy the Thousandriver and disable Vulcan and Valkyrie's A.I chips, stripping them of their transformation abilities. When a confused Gai questions Ark-One for why he didn't kill them, Aruto cancels his transformation and angrily orders them to stay out of his way because he thinks that this battle is just between him and Horobi alone. He then tells them to leave him alone and leaves.

At the base of MetsubouJinrai.net, Aruto continues to try to find Horobi, but again to no avail. Due to these failures, he starts to slowly lose his temper and sanity until Azu arrives to try to comfort him as his secretary, even saying that she changed her hair color to fit his preferences. However, Aruto angrily replies to her that his secretary can only be Izu and her alone, while telling her to leave him alone as well. Azu then tells him that she has found Horobi's location, to which he quickly and anxiously asked her where he is.

After arriving at Horobi's location, Aruto asked him if he felt any pain at all in his heart after destroying Izu, which Horobi replied that he doesn't have such a thing, and as long as there's malice in human hearts, he will continue to fight as a Kamen Rider. Aruto finally declares that he will never forgive Horobi, and both of them transformed into their Rider forms. During their battle, while Horobi has himself and his Magia army, all of them still don't stand a chance against Ark-One. Ark-One continues to brutally beat Horobi with attacks full of rage, though Horobi also didn't hesitate to strike back with his blows. However, Ark-One had the upper hand regardless, stopping his sneak attack and even destroying his Attache Arrow. At the end of their fight, Horobi attempted to finish Ark-One with the Sting Dystopia, but was forcefully stopped by his punch powered by the learning level of Malice all the way to Annihilation. Ark-One then powered himself up with the learning level of Extinction, about to end Horobi once and for all with the Perfect Conclusion: Learning End. However, Jin flew to Horobi at the very last second and took the fatal blow for him, completely obliterating him in the process. Realizing what he had done to his former ally, Aruto broke down and retreated while trembling in horror.^{[That is a Heart]}

Final Clash with Horobi and Zero-One's Return

File:Arkscorpion vs arkzero.png

A few days later, Horobi saw Aruto arrive on the stage of their final battle; the former realized that the latter had come to his own conclusion, with Aruto noting that Horobi did the same. As the two equipped their Drivers, Azu was delighted in broadcasting the final battle to the world as everything was going by the Ark's predictions. Aruto then transformed into Ark One, while Horobi accessed his final form, Ark Scorpion. The two grabbed nearby Attache weapons, and ran towards each other as the final battle for their respective kinds began.^{[There's Only One Person Who Can Stop You]}

Horobi's new form was proven to be on par with Ark-One, as he managed to keep up with him and send him straight down into a parking lot. However, Aruto, having found guidance in the form of Soreo Hiden, started to hold back and refuse to fight. Enraged by this, Horobi proceeded to destroy both the Ark Driver-One and the Ark-One Progrisekey by unleashing the Hatred Impact. Cancelling his transformation, Horobi angrily questioned Aruto why he had stopped fighting, but Aruto revealed that he now understood what Horobi was really feeling, saying that no one wouldn't cry if their family was taken away from them. Horobi suddenly proceeded to finally lash out in anger and grief over losing Jin, blaming his son's death on Aruto via punching him. As Aruto fell to the floor, he grabbed and clenched Izu's burnt ribbon, declaring that Horobi finally understood the heart through rage and sorrow. Horobi attempted to deny it again, but he suddenly had a flashback of his template and "brother" Soreo's death during the Daybreak Town Accident, realizing that Aruto had lost family as well, making them kindred spirits in a way. He then had a flashback of himself killing Izu, causing him to somberly declare that Jin's death was also his fault. A saddened Horobi fell to his knees, finally admitting that he was actually scared of his own heart growing within him, and how he had failed to understand it. When Aruto attempted to comfort him, Horobi lashed out again and punched him, screaming that his heart was the reason why he hated Aruto and humanity for giving him something he couldn't understand. Aruto then yelled at Horobi to overcome his grief, now that he admitted to having a heart. He then declared to Horobi that they were Kamen Riders, after all, and decided to finish their battle out of catharsis. Aruto's willpower caused the Rising Hopper Progrisekey to transform into its Realize Version, which he used to transform into Zero-One Realizing Hopper, much to Azu's bewilderment. During their battle, Horobi declared that while he hated Aruto from the bottom of his heart, neither him nor humanity deserved extinction of any kind. Zero-One's new form overpowered Horobi and was about to finish the battle with the Realizing Impact. As the finisher was about to strike him, Horobi chose to stand still and take the massive hit, which destroyed the Zetsumetsu Driver and the Ark Scorpion Progrisekey. Despite being heavily damaged, Horobi was left alive; when questioning Aruto why his finisher didn't kill him then and there, Aruto revealed that he restrained his final blow and that there was no need for killing anymore. Horobi then solemnly accepted his defeat.

After the war between humans and Humagears was ended, Aruto held a press conference about a new satellite that will replace Zea while developing the Humagears business, as well as how to recognize and how to use Humagears properly. ^{[The Future of Each]}

Eden's Paradise

3 months after the Ark has been destroyed, Aruto recieved a message from S, who tells him that he's going to create his Paradise, and provocating him into a fight. He concludes that the Ark is yet not defeated, and go meet him, not allowing Izu to come with him, as it's too dangerous, but she instead should inform others about the situation. He, at some point, transformed into Kamen Rider Zero-Two and joined S, as Kamen Rider Eden, in his place and fights him violently as the 60-minute countdown has already started.

Zero-Two is defeated by the Eden Impact, and gets his Zero-Two Driver taken. He tries to use his Rising Hopper form, but is thrown away by Eden's attack. He lands on a car, and faints, waking up in a moving metro train. The train stops, but Aruto notices that there are people laying unconscious on the floor of the station. He spots an unknown woman from afar and tries to join her, where she tells him that it's weird that he's still conscious while in "this world".

Aruto wonders what is the place he is in, what she replies that it's Hell because that's basically where people are sent when dead. He also asks her about S, what she replies he doesn't need to know. Aruto convices her to tell what's happening. She tells him that S is Isshiki Raito, who until 13 years ago, was the leader of a nanomachine research team, that she was part of his team, and that he gave up his humanity since then by virtualizing his mind, letting his original body dying. Aruto and her now enter a chapel.

Aruto remarks that objects in the world he is in are not physical. The woman shows him a Thousand Jacker planted in a stone, and tells him that Isshiki would create a key to make the world a Paradise, revealing why he was looking for Zea's power of creating Progrisekeys. Aruto then witnesses her trying to remove the Key from the Thousand Jacker, but with no success, making her losing hope about stopping Isshiki and saving the world. Aruto promises her that he'll stop him instead, what she doesn't believe in (since trapped in Hell), until she realizes why he's conscious: he's not in the Hell as the same way as others. Zea actually connected Aruto's mind to this world for the meeting to happen. Aruto's mind vanishes to reach his body, but not before the woman asks him to talk about her to Isshiki.

Aruto wakes up on the car he landed on 17 minutes earlier. He attempts to call the Rise Hopper, but Ikazuchi arrives with a truck ready with the Rider Machine. Aruto then rides to where Rihito/S is, and uses MetalCluster Hopper form to fight Eden. As Eden uses nanomachines for his body, he is completely invulnerable, making Zero-One mad about his use of technology. However, he gets the idea to use his Cluster Cells to immobilize Eden and allow him to deliver a few attacks. Eden then uses the Thousand Jacker with the newly created Hellrise Progrisekey as an attempt to destroy Zero-One. The heroic rider tries his best to prevent Eden, unfortunately fails, but the impact destroys the building, and the Rise Hopper, as well as killing the majority of Eden's followers who were gathered around the building.

Aruto's transformation cannot be kept, but he could still follow Rihito/S to the real version of the chapel. When the latter was about to insert the Hellrise Progrisey into the Thousand Jacker, Aruto takes the Progrisekey from his hands, but not to destroy it. He then decides to transform with it, but Rihito/S tells him that it's going to kill him. The Progrisekey makes him transform into Hellrising Hopper, a form that makes him go berserk, and lets him regenerate severe wounds almost instantly.

Eden tries to take the Progrisekey back, but Zero-One creates an explosion canceling Eden's transformation. Rihito/S was almost hit by the Hellrising Impact and survived if Izu as the new Kamen Rider Zero-Two hadn't takes the hit. Due to the impact, her transformation is cancelled. Izu manages to help Aruto regain his consciousness and to cancel his transformation. Aruto later discards the Progrisekey.

Izu tells Aruto that she doesn't want to lose her President, and even recalls the time she got destroyed by Horobi. Aruto is confused as the new Izu's memory doesn't contafin this moment (in fact Is, just before coming in, had fused with a save of her memory made by Zea). Aruto realizes that his eventual sacrifice would have just made Izu sad, instead of making everyone happy. Rihito/S takes the Hellrise Progrisekey, and Aruto notices a ring on the floor, now understanding the situation and the reason why Rihito/S is doing this.

Horobi sends Izu and Aruto the image he found of a Humagear with a human brain. Aruto understands that this brain is the earlier woman's, who is no other than Rihito's/S' fiancee, Akane Tono, because he noticed that she wore the same ring that fell from Rihito's/S' possession during their earlier battle. Horobi tells that Akane was the subject for a nanomachine treatment test, and died during the Daybreak Town Accident when the nanomachines were hacked to attack rather than treat her. Aruto tells Rihito/S that he understands what he's doing: he virtualized his fiancee's mind in a virtual world he calls Paradise, and is about to do the same with every human on Earth, and next, he'll destroy everything on Earth for his Paradise to be lone. Rihito/S confirms that he tried to create his Paradise in 60 minutes, in the same way Akane died in 60 minutes, but the thing is that she very probably hates him for not being able to save her. Aruto then tells that Akane doesn't want a world like this, and that she doesn't hate him for not managing to save her from death.

Realizing this, Rihito/S goes over to the Thousand Jacker, but is shot by Behru, who realized the Paradise was only for Akane. Behru, after declaring he will create his own paradise, takes the Eden Driver becomes Kamen Rider Lucifer. Aruto gives back the ring to Rihito/S, and saves him from being attacked, allowing him to flee. Aruto and Izu then face against Lucifer and the Abbadon Riders as Zero-One and Zero-Two respectively.

"There are people who can stop you, and that's us!"

―Aruto and Izu to Behru

Zero-One and Zero-Two finish Lucifer with the combination of Realizing Impact and Zero-Two Big Bang, destroying the data center where the virtual world was stored, thus deleting Rihito's/S' and Akane's data. Aruto thanks Izu for saving him. Izu then asks why he knew that Akane would wait for Rihito/S, since Zea didn't predict it. Aruto reveals that Akane told him that she was actually ill and that was the reason Rihito/S made her the first test subject for nanomachine treatment. The heroes leave the chapel while Aruto delivers another one of his jokes. ^{[Kamen Rider Zero-One: REAL×TIME]}

Other Events

Kamen Rider Zi-O: Over Quartzer

Main article: Aruto Hiden/Over Quartzer

Zero-One appears in Sougo's dream

The following events take place in an alternate timeline not related to the prime version.

During one of Sougo Tokiwa's dreams, he saw Black Woz introducing Kamen Rider Zero-One. He wakes up in a panic, claiming that Zi-O had disappeared in his dream and the new Rider had taken his place, and the crowd started chanting his name.

Zero-One later appears to face the heavily injured Kamen Rider Zonjis, introducing himself to be the only one for being the true first Reiwa Kamen Rider, Zero-One. Aruto fended off the Kasshines and defeated Zonjis easily by using his Rising Hopper and Flying Falcon forms.

Kamen Rider: Reiwa The First Generation

"There's only one person who can stop you, father, and that's me!"

―Aruto vows to stop his out of control father, Soreo Hiden^[src]

Aruto wakes up from a dream he had of the Daybreak Town Accident. Realizing that he was late, he hurriedly rushed out of his apartment for Hiden Intelligence, spotting several types of Humagears he didn't know existed on the way. Arriving at the building, he is subdued by the Humagears in the building and is shocked to discover that there was a new CEO, Will, who attacks him as Another Zero-One.

Aruto is thrown out of the building and activates his Driver and transforms into Zero-One to fight him, but his powers were sapped away shortly and his Driver taken. With no choice left, Aruto runs from the Humagears attacking him in public led by the Berotha Magia and Okureru as the Kuehne Magia. He was later rescued by Isamu Fuwa and Yua Yaiba and taken to the human resistance. After meeting Izu, who explained that there was a temporal disturbance in their universe, a platoon of Humagears led by Will, Horobi, and Jin began to raid the resistance base. Due to the creation of Another Zero-One caused by Time Jacker Finis, Aruto cannot transform into Zero-One again. Thus, he is forced to use the Forceriser to become Kamen Rider ZeroZero-One. Much to his shock, he is also forced to fight Soreo Hiden, his "father". In the midst of the resistance's defeat, Zi-O's team arrived and were successful in driving the Humagear force back. After explaining that the cause of this was due to Finis, a Time Jacker, Aruto goes back to 2007, 12 years in the past with Zi-O's team.

Arriving in 2007, Aruto and the Zi-O team reach the development factory and fights the Humagears that were terrorizing the workers. Aruto confronts Kamen Rider Ichi-Gata, whom he recognized as his father at the time. Soreo revealed he was doing this in order to bring happiness to Humagears, and was seemingly willing to bring down humanity to do so. He revealed that he was working on the Ark Satellite, which caused the events to happen in the present day.

Having the power of Another Zero-One, Will attacks Soreo, who also revealed that he was planning on destroying the satellite so that humanity doesn't fall. Both Aruto and Soreo transform to fight Will, but he takes them both down and stops Soreo's bomb. Satellite Ark then launches into space, activating its control over all the Humagears on Earth. Will returns to Hiden Intelligence and kills Korenosuke while Soreo, now controlled by the Ark, attacks Aruto. Another 1 arrives in their area, and Geiz saves Aruto, telling him that there's nothing else they can do in that time period. Sougo picks them up and they return to 2019.

Returing to the resistance base, the resistance tell Aruto that Izu gave herself up to stop the attack and was taken by Will. Aruto heads over to the conference center and exclaims his dream of a coexistence between human and Humagear. After Soreo reveals himself in the audience, Shesta announces that an emergency vote will occur at this point, for as to whenever Aruto should become president. As Soreo held the majority of the stocks at the company, his vote is absolute. In the end, he voted no, and the Ark corrupted every single HumaGear in the audience, in which Will sends to attack Aruto. In the lobby, the resistance as well as Zi-O's team arrive to help fight the Humagears. Aruto faces his father and announces his intent to defeat his father and regain his powers.

Aruto continues his fight with this father, who ultimately let his son defeat him, later revealing he was faking his evil nature this whole time, to ensure that Aruto was serious about having both human and Humagear coexist. With his death and "yes" vote, Aruto becomes president and receives the Zero-One Driver.

Another 1 absorbs Geiz's Time Mazine and becomes Another New 1. The Zea satellite is launched, and Aruto transforms into Zero-One to help Zi-O fight Another 1. Zero-One attacks her with Rocking Kaban Strash, and they attack her with other Progrisekeys and GrandZi-O. They finally finish her with their combined 'Rising Impact Time Break'. Everything returns to normal. Daybreak Town, Soreo, and Ark meet their original fates once again.

Later, Aruto and Team Zi-O meet again. Woz tells Aruto that everything has turned back to normal and only him and Izu will remember the events due to being connected to each other through Satellite Zea. Before leaving, Sougo says that he must erase Aruto's memories as well in order to return everything to normal. Aruto resists and both of them transform and engage into a friendly duel.

After the events of the movie, Aruto misses Soreo while staring at the Humagear body in his office. When Izu arrives, he asks her to change the design of his business cards and explains it, but Izu remembers Aruto's recent journey through timeline.

Personality

Aruto is a cheerful individual who will go above and beyond to make those around him happy, even though he is horrible at it. He strongly believes that like humans, Humagears can indeed possess a heart and have dreams of their own, enabling them to prosper alongside humanity. To this end, Aruto became Zero-One to fight against those who he feels threatens that ideology, though this ultimately clouds his judgement of them, especially with ones he had previously developed a strong bond with and prioritized their safety and dignity over profits of the business world. This would eventually lead to his loss in the Workplace Competition against Gai Amatsu, a certified expert in the field.

After becoming the Ark itself, Aruto willingly discarded much of his comedic and lighthearted traits, now becoming cold, serious, and vengeful towards Horobi specifically; despite having previously sympathized with the Humagear's unwilling affiliation with the Ark, Aruto now seeks revenge on him for Izu's death, as she was his only family after the deaths of his biological kin. Aruto considered his former allies as enemies if they interfered with his desire for vengeance against Horobi, though he manages maintain enough of his composure to not kill them on the spot. Despite his fall from grace, Aruto is completely aware of his actions and thus grieves with the consequences of what he has become. After briefly seeking advice from his father, Aruto's final clash with Horobi served to teach the latter the meaning of the human heart. ^{[The Future of Each]}

Aruto is known for his good nature and polite manners, as evident towards his usage of "-san" when speaking with Isamu and Yua. However, his lack of honorific use towards Gai indicates his total loss of respect for such.

Aruto has several catchphrases he frequently uses throughout the series:

• Introduction after transformation: "Zero-One! That's who I am!" (ゼロワン、それが俺の名だ!, Zero wan, sore ga ore no nada!)
  • Variation on Episode 40: "Kamen Rider Zero-Two! That's who I am!" (仮面ライダーゼロツー。れが俺の名だ!｜Kamen Raidā Zerotsū, sore ga ore no nada!, "Kamen Rider Zero-Two! That's who I am!")
• Pre-battle catchphrase: "There's only one person who can stop you... and that's me!" (お前を止められるのはただ一人…俺だ！, Omae o tome rareru no wa tada hitori... ore da!).
  • Aruto says a variation of this in Kamen Rider: Reiwa The First Generation: "There's only one person you can stop you Dad... and that's me!" (父さんを止められるのはただ一人…俺だ!, Tōsan o tome rareru no wa tada hitori... ore da!).
  • In Kamen Rider Zero-One: REAL×TIME, both Aruto and Izu say a variation of this: The ones who can stop you... are us! (お前を止めるのは...俺たちだ!, Omae o tomeru no wa... oretachi da!).
• Comedic gag outro: "Yes! It must be me, Aruto!" (はい、或人じゃないと！, Hai! Aruto Ja... Naito!)

Aruto has also given playful nicknames to his Progrisekeys, calling Flaming Tiger "Tora-chan" (トラちゃん, "Tora-chan"), Flying Falcon "Tori-chan" (トリちゃん, "Tori-chan") and Biting Shark "Same-chan" (サメちゃん, "Same-chan").

Powers and Abilities

Powers

• Enhanced Thought Processing: With the Hiden Zero-One Driver equipped, Aruto's mind is uplinked into Satellite Zea, which exponentially enhances his thought synapses allowing him to learn and analyze fighting techniques at a speed rivaling that of an A.I. supercomputer. This ability is carried over to the Zero-Two Driver as well, which further enhances Aruto's speed-thinking even more, to the point of allowing him to physically outperform the Ark's prediction capabilities. While connected to Zea, Aruto is able to communicate with Izu at any given point they wish. He is also capable of connecting to foreign virtual spaces, particularly Thinknet and speak with Akane Tono.
  • Temporal Protection: Due to being linked to Zea, Aruto can recognize and be immune to any temporal changes in the timeline, as he was able to discern a temporal difference that occurred 12 years ago. ^{[Kamen Rider: Reiwa The First Generation]} Aruto was also able to retain his memories of the alternate timeline even after his duel with Zi-O. ^{[I'll Save the Humagears]}

Abilities

• Skilled Combatant: Despite his lack of combat experience prior to becoming Zero-One, Aruto's combat skills had improved so much that Satellite Zea was unable to keep up, thus it originally deemed Shining Hopper unsuitable for him. Aruto would later go toe-to-toe against Thouser and several Battle Raiders simultaneously in his default Rising Hopper form. Aruto further demonstrates this when he fights Kamen Rider Ark-Zero on near even terms, despite being statistically weaker than him.
• Above Average Physical Strength: Though rarely demonstrated, Aruto has shown to perform extraordinary feats of resilience and strength when in critical situation, like withstanding a blow from the Attache Calibur to his shoulder untransformed^{[Kamen Rider: Reiwa The First Generation]} and later throwing the same weapon with enough speed and precision to stop a blast from Behru as Kamen Rider Lucifer from killing Rihito Isshiki a short distance away.^{[Kamen Rider Zero-One: REAL×TIME]} Moreover, he is able to hold back Isamu Fuwa, who has extraordinary physical strength, and a transformed Horobi before transforming himself.
• Businessman: Aruto has no prior business knowledge of any form, and is deemed incompetent in handing and executing the responsibilities of a company president. Gai, the CEO of ZAIA Japan, was able to exploit this experience when he challenged Aruto in the Workplace Competition and masterfully exemplified the qualities needed to be successful in the business market by achieving certain objectives (e.g. producing quality products, achieving profit margins, securing the support and confidence of customers). Gai was able to win the competition with a three to five victory (though these were achieve through underhanded means) based on those qualities that Aruto lacked. However, as he gained more experience, his business skills has shown to improve as he was able to operate HIDEN Manufacturing successfully with the help of Izu, which focusing his efforts on recovering discarded Humagears using the Humagear Progrisekeys.

Weaknesses

• Zero-One Driver Authorization: Zea is authorized to grant full usage of the Zero-One Driver specifically to Aruto alone, but he must be a currently active CEO for the recognition to take effect, otherwise Aruto cannot transform.

Former Weaknesses

• Shining Hopper: Zero-One's Shining Hopper form requires a great deal of strength to properly function. This compounded in encounters with particularly strong adversaries, which demands more strength than usual to utilize the Shining Arithmetic and usually resulting in exhaustion after use. Extended use can potentially result in temporary paralysis or forced cancellation of transformation. Aruto becomes more accustomed to Shining Hopper over time thanks to the Assault Grip gaining new data for the Shining Hopper Progrisekey to clear the harmful effects.
• MetsubouJinrai Forceriser: As the Forceriser was designed by MetsubouJinrai.net for use by Humagears, Aruto suffered significant pain upon equipping the one given to him by his father. Fighting as ZeroZero-One also places a significant amount of strain on Aruto's body. Aruto was less affected in his later battles than after his first transformation, but he soon discarded the Forceriser after he managed to defeat Ichi-Gata.
• Ark: Any of Zero-One's forms that are connected to the Ark, such as Shining Assault Hopper, MetalCluster Hopper and Ark-One, carry the risk of making him more aggressive and unable to control his rage.
  • Imprisonment Chain: A program malware created by the Ark, which is secured within the data of the MetalCluster Hopper Progrisekey. Originally, using the MetalCluster Hopper Progrisekey will cause an error on the Zero-One Driver, forcefully transfers the connection of Zero-One to the Ark instead of Zea, trapping Aruto's mind inside the Ark while his body, driven by the Ark's malice, attacked anyone in sight. In addition, it caused the Zero-One Driver to be unable to authorize any other Progrisekey. To counteract this, Izu created the Progrise Hopper Blade, which restored Zero-One's connection to Zea, avoiding the Ark's influence and completely erases the malware a whole, as well as restoring the Zero-One Driver's full functionality.
  • Ark-One: Physically speaking, Aruto has countermeasures to fight against the Ark. However his longing to avenge Izu's death caused him to willingly align with the Ark, turning him into Ark-One. The malicious aura that came with the powers constantly keeps Aruto in pain, reflected by his grief and cries; and can even be forced out of his transformation should he use too much power. In later episodes, Aruto shows less strain when using this form, now presumably being able to control it, but the aforementioned mental fallout still affects him. In addition, Ark-One indirectly caused Zero-Two, a form that is linked to Zea, to gain a tiny fraction of its malicious power. Aruto no longer has this weakness, as his Ark Driver and Ark-One Progrisekey was destroyed by Horobi, returning him to his former glory.
• Hellrising Hopper Progrisekey: The Hellrising Hopper Progrisekey was not meant for human use, so it had severe negative effects when used by Aruto to stop S. The two major consequences were Aruto succumbing to intense anger and wildly attacking his surroundings, and the form causing Aruto excruciating pain and even forcibly fixing broken limbs to continue fighting. These drawbacks were lost when Aruto discarded the Progrisekey and the Key was eventually destroyed, causing Aruto to lose the form entirely.

Rising Hopper (ライジングホッパー, Raijingu Hoppā) is Zero-One's grasshopper-based primary form accessed by using the Rising Hopper Progrisekey in the Hiden Zero-One Driver.

While it serves at Zero-One's balanced default form, Rising Hopper excels at jump height and kicking power, outclassing all of his other main forms as well as other Riders in these areas due to using grasshopper data.

Rising Hopper consists of the following parts:

• Hopper Head (ホッパーヘッド, Hoppā Heddo) - The head.
  • Hopper Mask (ホッパーマスク, Hoppā Masuku) - Rising Hopper's faceplate. It protects the face and reproduces the capabilities of grasshoppers to extend the wearer's capabilities.
  • Zero-One Signal (ゼロワンシグナル, Zerowan Shigunaru) - The Zero-One system's control device. Located between the eyes. It has a role of controlling the signaling system for adapting to various Progrisekeys, matching and information transmission loss with the wearer, adjustment to close the ability extension to the theoretical value by checking such as defects is performed.
  • Hopper Antenna (ホッパーアンテナ, Hoppā Antena) - The antenna. By adopting an active method for performing directional control by changing the phase and wavelength, it is possible to detect even the smell by introducing the state-of-the-art olfactory element.
  • Hopper Eyes (ホッパーアイ, Hoppā Ai) - The compound eyes. Different image sensors of the method are assembled in compound eye shapes, it is possible to extract a variety of information, including thermography and X-ray imaging by combining with image processing. In addition, it is also possible to view high-altitude observation information from the communication satellite Zea (ゼア, Zea).
• Rise Architecter (ライズアーキテクター, Raizu Ākitekutā) - The black undersuit. It is a human strengthening system that uses electromagnetic induction to activate the wearer's physical abilities and brings out superhuman strength. The material is a woven fabric made of a special fiber Hiden Hexa Fiber (ヒデンヘキサファイバー, Hiden Hekisa Faibā) with excellent toughness and soft metal fiber Hiden Amorphous Line (ヒデンアモルファスライン, Hiden Amorufasu Rain), and it is very thin and supple though it is woven together with information cables. Inside, the liquid armor n-NA ((「n-NA」), n-NA), a kind of non-Newtonian fluid with excellent bulletproof and shock absorption, is enclosed, maintaining flexibility and maintaining the protection of the whole body. In addition, as basic equipment of the Zero-One system, it is possible to develop and evolve by adding various abilities based on the data of the Progrisekey.
  • Architecter Head (アーキテクターヘッド, Ākitekutā Heddo) - The Rise Architecter's helmet parts; the black parts of the helmet. The human strengthening system using electromagnetic induction activates the wearer's physical abilities and brings out superhuman strength. Just like the Rise Architecter, it is made up of Hiden Hexa Fiber, Hiden Amorphous Line and contains n-NA within it.
  • Architecter Shoulder (アーキテクターショルダー, Ākitekutā Shorudā) - The shoulders, made of Hiden Alloy (ヒデンアロイ, Hiden Aroi), with a Knoop hardness of 8200, the shape with excellent aerodynamics disperses the kinetic energy of impacts and shells, and by deflecting it, it increases the defense performance and reduces the air resistance on itself Improve even motility.
  • Hiden Linker (ヒデンリンカー, Hiden Rinkā) - The collar armor piece, made of soft metal Hiden Amorphous (ヒデンアモルファス, Hiden Amorufasu) armor by neuronal connection of the wearer's body using a pseudo-impulse, to provide a reflection speed to correspond to the calculation speed obtained by the data link with the communication satellite Zea.
  • Architecter Arms (アーキテクターアーム, Ākitekutā Āmu) - The arms. It allows the Rise Architecter to pull out superhuman feat from the wearer and can lift up to 3.2 tons of objects.
  • Architecter Grab (アーキテクターグラブ, Ākitekutā Gurabu) - The hands. It is possible to extend the sensitivity of the sense of touch by increasing the gripping power by drawing out superhuman force from the wearer.
• Hopper Breast (ホッパーブレスト, Hoppā Buresuto) - The chest plate. It comes with a built-in the respiratory and hearing device Rising Lung (ライジングラング, Raijingu Rangu) and the ability of the wearer is extended by reproducing the function of the grasshopper as well as protecting the chest and abdomen.
• Hopper Legs (ホッパーレッグ, Hoppā Reggu) - The legs. It is equipped with a jumping device Rising Jumper (ライジングジャンパー, Raijingu Janpā), allowing 60.1m of jumping in vertical jumps. This protects the thigh and reproduces the function of the grasshopper to extend the wearer's ability.
• Hopper Greaves (ホッパーグリーブ, Hoppā Gurību) - The shin guards. It is equipped with a dampening device dubbed Rising Absorber (ライジングアブソーバー, Raijingu Abusōbā) which absorbs the shocks created by propelling one of the ground and landing, preventing the user's legs from self-destructing. It protects the shins and reproduces the function of the grasshopper to extend the capabilities of the wearer.
• Hopper Boots (ホッパーブーツ, Hoppā Būtsu) - The feet. It is made of Hiden Alloy, with a Knoop hardness of 8200, increasing the destructiveness of kicks and defensive power.

This form has the following finishers:

• Hiden Zero-One Driver finishers:
  • Rising Impact (ライジングインパクト, Raijingu Inpakuto): Zero-One first launches the enemy into the air with a upward kick that creates an energy projection of a grasshopper leg. He then jumps into the air and kicks the enemy downward. As the enemy falls toward the ground Zero-One performs a final flying kick with an energy construct of a robotic grasshopper extending from his foot and breaks through the target's body.
• Attache Calibur finishers:
  • Kaban Strash (カバンストラッシュ, Kaban Sutorasshu): Zero-One augments the Kaban Strash with the power of the inserted Progrisekey.
    • Rising Hopper - Rising Kaban Strash (ライジングカバンストラッシュ, Raijingu Kaban Sutorasshu): Yellow energy is emitted from the Attache Calibur's blade before Zero-One delivers a downward slash followed by a horizontal slash.
    • Biting Shark - Biting Kaban Strash (バイティングカバンストラッシュ, Baitingu Kaban Sutorasshu): Beams of teal energy and a series of energy shark fins are projected before Zero-One slashes the enemy.
    • Rocking Hopper - Rocking Kaban Strash (ロッキングカバンストラッシュ, Rokkingu Kaban Sutorasshu): Zero-One charges the Attache Calibur with green and red energy before running up a large enemy, slashing them as he moves. He then leaps high into the air and performs a downward stab as he falls, causing a burst of green energy when he strikes the opponent.
  • Kaban Dynamic (カバンダイナミック, Kaban Dainamikku): By switching the Attache Calibur back to Attache Mode, charging it, changing it back to Blade Mode and inserting a Progrisekey, Zero-One can perform a Kaban Dynamic finisher with the power of the inserted Progrisekey.
    • MetalCluster Hopper - Metal Rising Kaban Dynamic (メタルライジングカバンダイナミック, Metaru Raijingu Kaban Dainamikku): Zero-One delivers two slashes to separate opponents, with each leaving a trail of combined Cluster Cells.

Flying Falcon (フライングファルコン, Furaingu Farukon) is Zero-One's falcon-based form, accessed by using the Flying Falcon Progrisekey in the Hiden Zero-One Driver.

This form decreases Zero-One's kicking power and jump height compared to Biting Shark and Rising Hopper, bringing him more in line with the other Riders, along with a slight decrease in running speed and a slight increase in punching power. However, Zero-One's decreases in stats are offset by Flying Falcon granting him the ability to fly.

Zero-One temporarily lost access to this form after the Flying Falcon Progrisekey was stolen by Kamen Rider Jin, but later regained it after the latter's destruction.

Flying Falcon adds the following parts:

• Falcon Head (ファルコンヘッド, Farukon Heddo) - The helmet.
  • Falcon Antenna (ファルコンアンテナ, Farukon Antena) - The Falcon's antenna. An active system is used that controls the directivity by changing the phase and wavelength. It also serves as a Pitot tube that measures airspeed.
• Falcon Mask (ファルコンマスク, Farukon Masuku) - Flying Falcon's faceplate. Equipped with antennas, visual devices, and enhanced hearing devices, it protects the face and expands the user's combat prowess with emulated falcon ability.
  • Falcon Eyes (ファルコンアイ, Farukon Ai) - The two green compound eyes. A combination of image sensors of different methods in a compound eye shape, combined with image processing, can extract a variety of information including thermo and X-ray imaging. It is also possible to use high altitude observation information from the communication satellite Zea as its own field of view. In addition, because it is constantly exposed to high-speed wind, the protective visor is layered to prevent damage from flying objects and ensure visibility.
  • Zero-One Signal (ゼロワンシグナル, Zerowan Shigunaru) - The Zero-One system's control device. Located between the eyes. It has a role of controlling the signalling system for adapting to various Progrisekeys, matching and information transmission loss with the wearer, adjustment to close the ability extension to the theoretical value by checking such as defects is performed.
  • Falcon Ears (ファルコンイヤー, Farukon Iyā) - Audio detecting devices located to the sides the helmet (more specifically, where Rising Hopper's 'eyes' are). In addition to it being a normal hearing device, a pressurizing device, dubbed Active Pressure (アクティブプレシャー, Akutibu Pureshā), has been built in, has the role of maintaining a constant blood volume in the body by detecting rapid acceleration and adjusting the blood flow of the wearer, the narrowing of the visual field and color tone It plays a role in preventing vision abnormalities such as changes.
• Rise Architecter (ライズアーキテクター, Raizu Ākitekutā) - The black undersuit. It is a human strengthening system that uses electromagnetic induction to activate the wearer's physical abilities and brings out superhuman strength. The material is a woven fabric made of a special fiber Hiden Hexa Fiber (ヒデンヘキサファイバー, Hiden Hekisa Faibā) with excellent toughness and soft metal fiber Hiden Amorphous Line (ヒデンアモルファスライン, Hiden Amorufasu Rain), and it is very thin and supple though it is woven together with information cables. Inside, the liquid armor n-NA ((「n-NA」), n-NA), a kind of non-Newtonian fluid with excellent bulletproof and shock absorption, is enclosed, maintaining flexibility and maintaining the protection of the whole body. In addition, as basic equipment of the Zero-One system, it is possible to develop and evolve by adding various abilities based on the data of the Progrisekey.
  • Architecter Head (アーキテクターヘッド, Ākitekutā Heddo) - The Rise Architecter's helmet parts; the black parts of the helmet. The human strengthening system using electromagnetic induction activates the wearer's physical abilities and brings out superhuman strength.

They can be used to block/diverge landslides. By attaching the Mammoth Pressers to the legs, Breaking Mammoth can perform a special manoeuvre that maximises the weight and size of the Mammoth Pressers (seen during the Breaking Impact finishing move).
• Press Knuckles (プレスナックル, Puresu Nakkuru) - The hand units. It can demonstrate a maximum punching force of 25.2 tons. The Press Knuckles can be used in operations that require large machinery such as shovel machines; as it only requires Zero-One's thoughts to move, the Press Knuckles can do such operations with ease, increasing the success rate of rescue operations.
• Crawler Walkers (クローラーウォーカー, Kurōrā Wōkā) - The legs. Thanks to a high-neuron connection system that connects to Zero-One's Base Architecture bodysuit, Zero-One can move the arms just by imagining the feeling of leg movement. Its posture control system adopts an operating system dubbed "Postec Ver. 2.2" (ポステックVer.2.2, Posutekku Ver. 2.2) that controls Breaking Mammoth's linear actuator drives to adjust and stabilise the heavy machine's balance. The left and right shins house power units dubbed Rise Engine HD-6080 (ライズエンジンHD-6080, Raizu Enjin HD-6080) that supply all off Breaking Mammoth's power. They have jet engines (which work within and out of the atmosphere) that allow Breaking Mammoth to reach up to Mach 7 within the atmosphere when in jet form.
• Mammoth Nails (マンモスネイル, Manmosu Neiru) - The feet. The claws on the tips are made of Space Hiden Alloy, which has the processing capabilities of six bulldozers, allowing Breaking Mammoth to perform walking operations on any road surface regardless of the road's condition. In jet form, the Mammoth Nails also function as a jet engine injection port.
• Break Top (ブレイクトップ, Bureiku Toppu) - Jet Form's 'nosecone'. It is composed of Space Hiden Alloy. A special field generator dubbed Break Air (ブレイクエア, Bureiku Ea) is installed inside, improving the structural integrity Breaking Mammoth requires when it is transformed into quantum particles by Zea. The Break Top suppresses sonic booms during high-speed flight, increasing speed and minimising the potential impacts caused by resulting shockwaves. In Mecha Form, the Break Top is located on the back.

This form's finisher is the Breaking Impact (ブレイキングインパクト, Bureikingu Inpakuto): Zero-One launches one of the Mammoth Pressers into the air, followed by it projecting a larger energy construct of itself. He then leaps into the air and lands on the Mammoth Presser before using it to crush the enemy beneath him.

• Maximum Running Speed: 100 m per 2.3 seconds

Shining Hopper (シャイニングホッパー, Shainingu Hoppā) is Zero-One's upgraded form, accessed by using the Shining Hopper Progrisekey in the Hiden Zero-One Driver.

Compared to Rising Hopper, Shining Hopper offers a moderate boost to Zero-One's punching power, kicking power, and jump height while more than doubling his maximum running speed. This form's main ability is to simulate a variety of combat patterns and choose the most advantageous one at the last second, in practice allowing him to dodge the enemy's attacks and counterattack from unexpected angles. Even if the enemy targets where they think Zero-One will be, Zero-One can still redirect his attack trajectory.

Initially, this form was deemed incomplete as it was unable to keep up with Aruto's growing combat potential. The insufficient combat data needed resulted in this form being only 1.8 times more powerful than Rising Hopper, as calculated by the Dodo Magia. However, after adding in the combat data from Zero-One's four auxiliary Progrisekeys as well as Wazu Nazotoku's central memory, Shining Hopper's power output is boosted, now being at least five times more powerful than his base form, as noted by Gai Amatsu.

While being more powerful than any of Zero-One's previous forms, using Shining Hopper demands a significant amount of Aruto's strength. Thus, Aruto may suffer fatigue after using it for long periods of time. The strain caused by this form is worsened when used multiple times consecutively, and may ultimately result in Aruto being forced out of his transformation.

In this form, Zero-One wields the Authorise Buster.

Shining Hopper is composed of the following parts:

• Shining Hopper Head (シャイニングホッパーヘッド, Shainingu Hoppā Heddo): The helmet.
  • Shining Hopper Mask (シャイニングホッパーマスク, Shainingu Hoppā Masuku): Shining Hopper's faceplate. It protects the face and reproduces the abilities of a grasshopper with an antenna and visual filter function. It is equipped with a high-performance computing device called Shining Arithmetic (シャイニングアリスマティック, Shainingu Arisumatikku).
    • Shining Arithmetic (シャイニングアリスマティック, Shainingu Arisumatikku): Shining Hopper's arithmetic processing unit. Located around the forehead. It predicts enemy behaviour by studying them and creates around 25,000 attack and avoidance patterns in consideration of Zero-One's own performance. From there, it is possible to find an optimal solution to a problem within 0.01 seconds. It's high-speed learning abilities can advance in battle.
  • Zero-One Signal (ゼロワンシグナル, Zerowan Shigunaru): The Zero-One system's control device. Located between the eyes. It has a role of controlling the signalling system for adapting to various Progrisekeys, matching and information transmission loss with the wearer, adjustment to close the ability extension to the theoretical value by checking such as defects is performed.
  • Shining Hopper Antennae (シャイニングホッパーアンテナ, Shainingu Hoppā Antena): The enhanced antennae. By adopting an active method for performing directional control by changing the phase and wavelength, it is possible to detect even the smell by introducing the state-of-the-art olfactory element.
  • Shining Hopper Eyes (シャイニングホッパーアイ, Shainingu Hoppā Ai): The compound eyes. Different image sensors of the method are assembled in compound eye shapes, it is possible to extract a variety of information, including thermography and X-ray imaging by combining with image processing. In addition, it is also possible to view high-altitude observation information from the communication satellite Zea (, ゼア).
• Shining Architecter (シャイニングアーキテクター, Shainingu Ākitekutā): The enhanced undersuit. The functions concealed within the usual Rise Architecter has been released and enhanced via high-density fusion with the Shining Hopper Progrisekey's Rider Model, which incorporates biomechanics. The chest and abdomen sections have become bigger due to the swelling of internal n-NA (, (「n-NA」)) non-Newtonian liquid armor, resulting in a surface layer that has been smoothed with ultrasonic binding to achieve high-speed movement, bounce performance and increased aerodynamic effect. Additionally, in addition to the normal human enhancement system that utilises electromagnetic induction, it has become possible for Zero-One to use an advance loan of power (力の前借り, chikara no maegari) force that draws out the potential of the wearer. However, despite the user gaining an advantage over an opponent's strength, Zero-One will be exposed to a heavy burden.
  • Shining Liner (シャイニングライナー, Shainingu Rainā): The yellow armor lines running throughout the body. In order for the Shining Arithmetic to process the most optimal solution, the Shining Liner is arranged at each part of the body and strengthens the Hiden Linker. Its main purpose is to improve the efficiency of each maneuver by controlling muscle movement and energy flow.
• Shining Hopper Shoulder (シャイニングホッパーショルダー, Shainingu Hoppā Shorudā): The shoulder armor. Special Shining Liner armor is arranged throughout, increasing the following ability of each maneuver. As a result, compared to Rising Hopper's Architecter Shoulder, defense range has been expanded, mobility has been improved and defensive ability has been increased.
• Hiden Linker (ヒデンリンカー, Hiden Rinkā): The collar armor piece, made of soft metal Hiden Amorphous (ヒデンアモルファス, Hiden Amorufasu) armor by neuronal connection of the wearer's body using a pseudo-impulse, to provide a reflection speed to correspond to the calculation speed obtained by the data link with the communication satellite Zea.
• Shining Gladiators (シャイニンググラディエーター, Shainingu Guradiētā): Four propulsion devices located on the shoulders and armpit areas. Propulsion by radiation pressure is obtained by emitting ultra-dense luminescent particles from the two outlets on the left and right side of the body. By utilising this propulsion ability Shining Hopper can achieve a three-dimensional behaviour that exceeds the speed of human movement; the speed assists the Shining Arithmetic function in calculating operations.
• Shining Hopper Arms (シャイニングホッパーアーム, Shainingu Hoppā Āmu): The arms. Allows the Shining Architecter to draw superhuman power from the wearer to lift objects up to 7.5 tons.
• Shining Hopper Grabs (シャイニングホッパーグラブ, Shainingu Hoppā Gurabu): The hands. The tips are equipped with Shining Liner armor bits, protecting the fingertips and dramatically increasing the destructive power of punches and weapons.
• Shining Hopper Legs (シャイニングホッパーレッグ, Shainingu Hoppā Reggu): The legs. The effects of the built-in Shining Jumper (シャイニングジャンパー, Shainingu Janpā), an evolved version of Rising Hopper's Rising Jumper devices, is distributed throughout the Shining Architecter undersuit, giving the whole body the strength of a strong spring. The leg has been adjusted to withstand particularly strong repulsive forces, enabling a completely vertical jump height of 93.9m. The Shining Hopper Legs reproduce the abilities of a grasshopper to expand the abilities of the wearer.
• Shining Hopper Greaves (シャイニングホッパーグリーブ, Shainingu Hoppā Gurību): The shin armor. An evolved dampening device called Shining Absorber (シャイニングアブソーバー, Shainingu Abusōbā) is built-in, and the mechanism for absorbing shocks has been strengthened to prevent self-destruction o the legs from recoil caused during jumps and kicks. The Shining Hopper Greaves reproduce the abilities of a grasshopper to expand the abilities of the wearer.
• Shining Hopper Boots (シャイニングホッパーブーツ, Shainingu Hoppā Būtsu): The feet. Shining Liner is arranged and integrated with the Shining Hopper Greaves, allowing Zero-One to utilize a wide variety of maneuvers in addition to kicking and jumping.

This form has the following finishers:

• Hiden Zero-One Driver finishers:
  • Shining Impact (シャイニングインパクト, Shainingu Inpakuto): Zero-One delivers a horizontal flying kick to the enemy, causing them to be pushed backward, before rushing toward them at extremely high speeds and delivering a roundhouse kick that that leaves behind a trail of yellow energy.
  • Shining Mega Impact (シャイニングメガインパクト, Shainingu Mega Inpakuto): Zero-One delivers high-speed punches and kicks to the enemy before launching them into the air with an upward kick. In the air, Zero-One continues to deliver a barrage of punches and kicks before performing a final flying kick covered in yellow energy that creates a blue energy emblem of circuitry and bursts through the target, destroying them.
• Authorise Buster finishers:
  • Progrise Dust (プログライズダスト, Puroguraizu Dasuto):
    • Rising Hopper: Zero-One fires a blast of yellow energy.
  • Zero-One Dust (ゼロワンダスト, Zerowan Dasuto): Zero-One charges the Authorize Buster before firing a yellow energy shard that briefly creates an image of a mechanical grasshopper before striking the enemy.
  • Buster Dust (スターダスト, Basutā Dasuto):
    • Freezing Bear: Zero-One warps behind an enemy and fires an energy construct of a polar bear's head into the target, destroying it.
  • Zero-One Buster Bomber (ゼロワンバスターボンバー, Zerowan Basutā Bonbā):
    • Biting Shark: Zero-One charges the Authorise Buster, then uses the Shining Arithmetic to dash around the enemy before jumping into the air. Once in the air, he creates two rows of blue energy shark fins and crushes the enemy between them, then performs the attack a second time with a second set of energy fins.

Shining Assault Hopper (シャイニングアサルトホッパー, Shainingu Asaruto Hoppā) is Zero-One's second upgraded form. This form combines the power of Kamen Riders Zero-One Shining Hopper and Vulcan Assault Wolf, accessed by using the Shining Assault Hopper Progrisekey in the Hiden Zero-One Driver.

In this form, Zero-One's punching power, kicking power, and jump height have all increased in comparison to Shining Hopper. However, this comes at the cost of his running speed, which is now equivalent to Vulcan Shooting Wolf. Unlike Vulcan Assault Wolf, Zero-One is able to use this form without his body being damaged.

In addition to still being able to use the Shining Arithmetic, Zero-One is now equipped with the Shine System, which exponentially increases his offensive and defensive capabilities and allows him to control the Shine Crysters, eight crystal-like energy constructs. Zero-One can form the Shine Crysters into a shield to guard him from attacks, have them autonomously launch themselves into a target, or fire laser beams from them.

However, due to this form's connection with the Ark via Assault Wolf, enough anger built up while using it carries the risk of causing Zero-One to go berserk.

Shining Assault Hopper is composed of the following parts:

• SA Hopper Head (SAホッパーヘッド, SA Hoppā Heddo): The helmet.
  • SA Hopper Mask (SAホッパーマスク, SA Hoppā Masuku): Shining Assault Hopper's faceplate. The irregular matrix frame is intricately entangled with the "shining hopper mask" to form a flexible structure. This makes the armor both hard and soft due to the rigidity of each armor and the structure that receives impact. In addition, it is equipped with a high-performance computing device "Shining Arithmetic", multiple antennas and enhanced visual devices, which protect the face and reproduce the function of grasshoppers to expand the ability of conformers.
    • Shining Arithmetic (シャイニングアリスマティック, Shainingu Arisumatikku): Shining Assault Hopper's arithmetic processing unit. Located around the forehead. It predicts enemy behavior by studying them, and creates around 25,000 attack and avoidance patterns in consideration of Zero-One's own performance.

  • Orbital Unit (オービタルユナイト, Ōbitaru Yunaito): The combat aid orb built in the SA Hopper Breast. By activating the built-in thought reaction wave unit Shine System (シャインシステム, Shain Shisutemu), it becomes possible to deploy the Shine Cryster (シャインクリスタ, Shain Kurisuta), a blue energy wave bullet. In response to Zero One's thinking, it is an integrated offense and defense equipment that performs shield formation in a densely populated manner and intercepts by spreading. In addition, the special lens on the front side functions as an irradiation molding machine called the Beam Equipper (ビームエクイッパー, Bīmu Ekuippā) and plays a role in irradiating and shaping the Shine Cryster.
• Shining Architecter (シャイニングアーキテクター, Shainingu Ākitekutā): The enhanced undersuit. The functions concealed within the usual Rise Architecter has been released and enhanced via high-density fusion with the Shining Hopper Progrisekey's Rider Model, which incorporates biomechanics.

MetalCluster Hopper (メタルクラスタホッパー, Metaru Kurasuta Hoppā) is Zero-One's super form, accessed by using the MetalCluster Hopper Progrisekey in the Hiden Zero-One Driver.

MetalCluster Hopper's armor is composed of robotic grasshoppers named Cluster Cells (クラスターセル, Kurasutā Seru), which attach themselves onto Zero-One's undersuit and change shape accordingly. When separated from Zero-One, the Cluster Cells are also able to form other structures, such as shields and spikes. This ability to freely change shape is possible due to the Cluster Cells being made out of Hiden Metal (飛電メタル, Hiden Metaru), a theoretical material created by Hiden Intelligence that can freely change its hardness, plasticity, and density.

This form's stats exceed all other Riders at the time of its debut, including Thouser. However, using this form originally trapped Aruto's consciousness in the Ark while his body, driven by the Ark's malice, attacked everyone in sight. However, using the Progrise Hopper Blade returned Aruto's consciousness to Zea, allowing him to use the form safely. Zea had initially concluded that this would have been the most powerful upgrade to Zero-One and that it could not be upgraded any further, prior to Zero-Two's creation.

In this form, Zero-One wields the Progrise Hopper Blade, which is also equipped with Cluster Cells, alongside the Attache Calibur. Before the creation of the Progrise Hopper Blade, when MetalCluster Hopper was under the control of the Ark, he instead wielded the Authorise Buster. Under the Ark's control Zero-One attacked with Cluster Cells directly from his body, while Aruto prefers to use the Progrise Hopper Blade to channel them.

MetalCluster Hopper is comprised of the following parts:

• MetalCluster Hopper Head (メタルクラスタホッパーヘッド, Metaru Kurasuta Hoppā Heddo): The helmet.
  • Direct Vector (ディレクトベクター, Direkutobekutā): The control antennae. Using two antennas, the Hiden Zero-One Driver can instruct the Cluster Cells.
  • Metal Mask (メタルマスク, Metaru Masuku): MetalCluster Hopper's faceplate. It protects the face and reproduces a grasshopper's ability (with antennas and visual devices) to increase the user's combat ability.
  • Metalling Hopper Antennae (メタリングホッパーアンテナ, Metaringu Hoppā Antena): The antennae located to the sides of the helmet. The active method that controls the direction by changing the phase and wavelength is adopted, and a state-of-the-art olfactory element can be used to detect smell. Additionally, by temporarily increasing its density and hardness, the sharp Spite Edges (スパイトエッジ, Supaito Ejji) can be used as an effective piercing weapon.
  • Eclipse Hopper Eyes (エクリプスホッパーアイ, Ekuripusu Hoppā Ai): The compound eyes. It contains a vast array of different types of image sensors, and can combine with image processing to extract various information such as thermography and X-ray photography. It also has a function to search for enemies by emitting special waves and narrow down the most effective targets.
  • Zero-One Signal (ゼロワンシグナル, Zerowan Shigunaru): The Zero-One system's control device. Located between the eyes. By invoking the forced interrupt program Prisonment Chain (プリズメントチェイン, Purizumento Chein), it is also possible for the Ark to connect to the Hiden Zero One Driver in order to perform remote control takeover via behavior correction. Until the Progrise Hopper Blade is created, the Prisonment Chain is now completely erased inside the data of the MetalCluster Progrise Key, which now usable for Zero-One to communicate with the Zea.
• Metal Breast (メタルブレスト, Metaru Buresuto): The special chest armor. The main material is Hiden Metal (飛電メタル, Hiden Metaru), a new theoretical material originally conceived by Hiden Intelligence. It is a special metal with phase transition control properties that can freely change its hardness, plasticity, and density. Hardness has the property of changing instantaneously in a range from liquid metal to Knoop hardness of 10800. Demonstrate high protection by optimizing the shape at the same time as the hardness change.
• Metal Shoulder (メタルサバトン, Metaru Shorudā): The shoulder armor. Taking advantage of the hardness change characteristics of the main component, Hiden Metal, the damage is greatly reduced by instantaneously adjusting the hardness to the optimal level against the impact received. In addition, the sharp Spite Edges arranged in various parts of the armor is effective as a piercing weapon by temporarily increasing its hardness and density.
• Metal Rebrace (メタルリブレイス, Metaru Ribureisu): The upper arm phase transition armor. A yellow-green MCH liner (MCHライナー, MCH Rainā) developed from Zero-One Shining Hopper's Shining Liner' is arranged in each part of the phase change armor of the whole body, controlling muscle movement and energy flow etc. to make each movement highly efficient. In addition, the muscular strength device Hopper Force (ホッパーフォース, Hoppā Fōsu) installed within draws superhuman power from the user, allowing Zero-One to exert destructive punching power and tremendous grip strength.
• Metal Gauntlet (メタルガントレット, Metaru Gantoretto): The special forearm armor. Cluster Cells (クラスターセル, Kurasutā Seru), robotic grasshoppers which MetalCluster Hopper is made from, and which have the ferocity of grasshoppers, have the ability to break down objects through contact by eroding the object at a molecular level, allowing Zero-One to create destructive punching power that can reduce any substance to ashes. This protects the forearm from the hand and reproduces a grasshopper's ability, extending the user's combat ability.
• Amalgamate Tector (アマルガメートテクター, Amarugamēto Tekutā): The powered undersuit. It is the Rise Architect undersuit with its versatility removed and strenghtened to maximise the abilities of MetalCluster Hopper. The liquid armor n-NA enclosed inside has been replaced with Hiden Metal, providing 8.4 times more defense and 1.6 times more flexibility than usual.
• Metal Cuisses (メタルキュイス, Metaru Kyuisu): The thigh phase transition armor. The built-in muscular strength booster Hopper Force draws superhuman power from the user, demonstrating devastating kicking power and amazing running power. Above all, the jump force is especially strong, and can vertically jump 102.9m. This protects the thigh and reproduces the ability of a grasshopper, enhancing the user's combat ability.
• Metal Greaves (メタルグリーブ, Metaru Gurību): The lower leg phase transition armor. The ability of the MetalCluster Hopper Progrisekey, Everybody Jump (エブリバディジャンプ, Eburibadi Janpu) acts on each part of the phase transition armor to provide self-replication and fusion ability, enabling the generation of grasshopper-type Cluster Cells. The Cluster Cells that have been formed in large group via high-speed replication can trigger an assault action titled Cluster Tempest (クラスターテンペスト, Kurasutā Tenpesuto) that attacks and defends through remote control. This protects the shin and reproduces the function of the grasshopper, extending the ability of conformers.
• Metal Sabaton (メタルサバトン, Metaru Sabaton): MetalCluster Hopper's legs. Taking advantage of the characteristics of Hiden Metal, which has phase transition control characteristics, it achieves both strength and flexibility, enabling active parameter adjustment during battle. This greatly improved not only defense but also mobility and the destructive power of kicks.

This form has the following finishers:

• Hiden Zero-One Driver finishers:
  • Metal Rising Impact (メタルライジングインパクト, Metaru Raijingu Inpakuto): This finisher has three variations:
    • Zero-One used Cluster Cells to creates two copies of himself, which each jump into the air and deliver flying kicks to separate enemies.
    • Zero-One generates a swarm of Cluster Cells, which forms into a copy of him. The copy delivers a flying kick to the opponent, then dissipates back into a swarm and forms into a drill. Zero-One then leaps into the air and performs a flying kick covered in green energy, which combines with the drill before striking the opponent.
    • Zero-One delivers several slashes to the opponent while being protected by Cluster Cells.
• Progrise Hopper Blade finishers:
  • Progrising Strash (プログリシングストラッシュ, Puroguraizingu Sutorasshu): This finisher has three variations:
    • Zero-One forms a jagged blade of Cluster Cells covered in blue electricity and launches it toward the enemy.
    • Zero-One delivers a horizontal slash to the enemy at close range, creating a jagged construct of Cluster Cells.
    • Zero-One swings the Progrise Hopper Blade, generating a swarm of Cluster Cells that destroys the enemy's weapon. He then moves towards the opponent and charges the Progrise Hopper Blade with blue energy before delivering a slash at close range, creating a jagged construct of Cluster Cells.
  • Final Strash (ファイナルストラッシュ, Fainaru Sutorasshu): This finisher has eight variations:
    • Zero-One generates a swarm of Cluster Cells that forms into metal spikes before swinging the Attache Calibur, sending them raining down on opponents.
    • Zero-One swings the Progrise Hopper Blade, sending a barrage of Cluster Cell projectiles at opponents.
    • Zero-One forms several walls of Cluster Cells to protect bystanders from the enemy's attacks.
    • Zero-One swings the Progrise Hopper Blade, forming two spiked tendrils from Cluster Cells that attack the opponents.
    • Zero-One is surrounded by Cluster Cells before delivering an upward slash to the opponent, creating a jagged construct from the Cluster Cells that shatters upon impact.
    • Zero-One leaps into the air and delivers a downward slash that creates a jagged construct of Cluster Cells
    • Zero-One slashes the opponent, creating a rotating chain of Cluster Cell spikes that further damage the enemy.
    • Zero-One swings the Progrise Hopper Blade, creating a swarm of Cluster Cells that flies through the opponent, leaving behind large holes. Unknown to the target, some Cluster Cells stay behind in their body as they regenerate. After the enemy has completely regenerated, the Cluster Cells inside the body burrow through and burst out once again. The Cluster cells continually tear apart the opponent's body to prevent them from regenerating.
  • Gigant Strash (ギガントストラッシュ, Giganto Sutorasshu): Zero-One forms a jagged blade of Cluster Cells and slashes the opponent, scattering the Cluster Cells upon impact, which proceed to tear apart the enemy. He then delivers a second slash with a much larger Cluster Cell blade that leaves behind a giant trail of flying Cluster Cells.
  • Ultimate Strash (アルティメートストラッシュ, Arutimeto Sutorasshu): Zero-One forms a jagged blade of Cluster Cells covered in blue electricity on the Progrise Hopper Blade and launches it toward the enemy, then uses the Attache Calibur to perform a long-range green energy slash. Finally, he performs a spinning slash that creates a swirling blade of Cluster Cells.
• Authorise Buster finishers:
  • Buster Bomber (バスターボンバー, Basutā Bonbā):
    • Breaking Mammoth: Zero-One creates a pair of silver mechanical mammoth leg constructs that charge at the enemy before delivering another slash that creates a silver construct of a mammoth tusk which rushes toward the target.

It has the role of controlling the signal transmission system for adapting to various progress keys, and makes adjustments to bring the capacity expansion closer to the theoretical value by checking matching with the wearer, information transmission loss, defects, and so on.
• Realize Hopper Breast (リアライズホッパーブレスト, Riaraizu Hoppā Buresuto): The chest armor. It has the "Realizing Lung" (リアライジングラング, Riaraijingu Rangu) built in and a hearing device to protect the chest and abdomen and reproduce the function of grasshoppers to expand the wearer's ability.
• Realize Architecter (リアライズアーキテクター, Riaraizu Ākitekutā): The suit. In addition to the human enhancement system that applies electromagnetic induction and protection with enclosed liquid armor, it is possible to activate "Realize" (リアライズ, Riaraizu) that re-reacts the Rider Model and produces ultra-high output, giving the wearer superhuman power. Realize is a system that produces ultra-high output beyond the limits of the driver itself by quantum-decomposing the progressed Rider Model, resizing the generated elementary particles, and reducing them to the Zero-One driver. This is because the driver is overloaded and the operating time is limited.
• Realize Architecter Shoulder (リアライズアーキテクターショルダー, Riaraizu Ākitekutā Shorudā): The shoulders. Made of the "Hidden Alloy" with a hardness of 8200 Knoop hardness, the shape with excellent aerodynamics disperses the kinetic energy of impact and shells, and by deflecting and flipping, it enhances defense performance, improves mobility and reduces air resistance applied to itself.
• Realize Architecter Arm (リアライズアーキテクターアーム, Riaraizu Ākitekutā Āmu): The arms. The "Realize Architect" suit grants superhuman power from the wearer and can lift an object of up to 22.4 tons.
• Realize Architecter Grab (リアライズアーキテクターグラブ, Riaraizu Ākitekutā Gurabu): The gloves. It is a part of the "Realize Architect" suit, and it can grant superhuman power from the wearer to increase grip strength and expand tactile sensitivity by about 14 times.
• Realize Hiden Linker (リアライズヒデンリンカー, Riaraizu Hiden Rinkā): Special armor. It's made of soft metal "Hidden Amorphous" (ヒデンアモルファス, Hiden Amorufasu) uses pseudo-impulses to connect the wearer's body to neurons, giving a reflex speed to accommodate the computational speed of artificial intelligence.
• Realize Hopper Legs (リアライズホッパーレッグ, Riaraizu Hoppā Reggu): The legs. Equipped with a jumping device "Realizing Jumper" (リアライジングジャンパー, Riaraijingu Janpā), it enables a vertical jump of 165.7m. This protects the thighs and reproduces the function of the grasshopper to expand the user's ability.
• Realize Hopper Greaves (リアライズホッパーグリーブ, Riaraizu Hoppā Gurību): The shin guards. Equipped with the "Realizing Absorber" (リアライジングアブソーバー, Riaraijingu Abusōbā) dampening device, it has a mechanism to absorb shocks to prevent self-destruction due to the reaction of strong leg force when jumping or kicking. This protects the shin and reproduces the function of the grasshopper to expand the wearer's ability.
• Realize Hopper Boots (リアライズホッパーブーツ, Riaraizu Hoppā Būtsu): The boots. The jump-specific adjustments have been made, and the armor made of the alloy "Hidden Alloy" with a hardness of 8200 Knoop greatly improves the destructive power and defense power of the kick.

This form's finisher is the Realizing Impact (リアライジングインパクト, Riaraijingu Inpakuto): Zero-One dodges the enemy's attacks at high speeds while moving toward them. Upon reaching the opponent, he delivers a side kick covered in green energy. He then leaps forward to the opponent again and delivers an uppercut covered in green and blue energy, followed by an upward kick that launches the opponent high into the air. Energy grasshopper feet briefly form around Zero-One's one feet before he leaps and knees the enemy in midair. Still in the air, Zero-One performs a series of high-speed kicks that leave afterimages of himself. He then leaps to different points in the air and performs more kicks, ricocheting the opponent between them, before delivering a downward kick that sends the enemy back to the ground. Finally, Zero-One performs a final kick with an energy construct of a robotic grasshopper extending from his right foot and an symbol similar to Zea behind him. A large energy representation of a DNA strand appears in his path when he strikes the enemy.

Hopping Kangaroo (ホッピングカンガルー, Hoppingu Kangarū) is Zero-One's kangaroo-based hyper battle form, accessed by using the Hopping Kangaroo Progrisekey in the Hiden Zero-One Driver.

The turquoise armor gives the user the abilities of a kangaroo and is equipped with the Kizuna Pocket (絆ポケット, Kizuna Poketto), which allows Zero-One to gain the power of a Humagear as his own. Nearby Humagear can be used to activate special attacks based on their occupations.

This form's finisher is the Hopping Impact (ホッピングインパクト, Hoppingu Inpakuto): An energy image of a kangaroo appears in front of Zero-One before he performs an uppercut, creating an energy construct of one of his gauntlets that launches the enemy into the air and leaves a trail of stars upon impact. Zero-One then drops onto his hands and does a backward kick with both feet, striking the enemy with an image of one of his feet. The enemy is then suspended in the air on a cartoon star, allowing Zero-One to deliver a rapid series of punches that create more energy gauntlets. Finally, Zero-One swings his arm in a circle before performing a haymaker punch that leaves an energy trail, destroying the enemy with a much larger energy gauntlet.

This form is exclusive to Kamen Rider Zero-One: What Will Pop Out of the Kangaroo? Think About It by Yourself! Yes! It must be me, Aruto!

Hellrising Hopper (ヘルライジングホッパー, Heruraijingu Hoppā) is Zero-One's berserk extra final form, accessed by using the Hellrise Progrisekey in the Hiden Zero-One Driver.

All of this form's stats slightly exceed those of Realizing Hopper, but it is still outclassed by Zero-Two. However, it makes up for this deficit with several abilities. In this form, Zero-One possesses some of Kamen Rider Eden's ability to regenerate, enabling him to heal injuries such as broken bones. However, because Aruto's body is not made of nanomachines like Eden's, this process is excruciatingly painful. In addition, Zero-One's body accumulates energy over the course of a battle until he ultimately releases it all at once in the form of a large explosion. Because this attack damages all of Eden's body simultaneously, it is one of the few things that is able to nullify his ability to regenerate and defeat him, forcing him out of transformation.

As the Hellrise Progrisekey was created with the intended purpose of destroying the world, a normal human should not be able to withstand using its power, as stated by S. One of the results of using it is that Aruto succumbs to rage and will relentlessly attack his opponent until they are killed.

Zero-One's finisher in this form is the Hellrising Impact (ヘルライジングインパクト, Heruraijingu Inpakuto): Zero-One's arm becomes red-hot before he runs toward the opponent and delivers a punch covered in light purple energy that creates a red shockwave upon impact.

Rising Hopper (ライジングホッパー, Raijingu Hoppā) is ZeroZero-One's grasshopper-based primary form accessed by using the Rising Hopper Progrisekey in the MetsubouJinrai Forceriser. He was forced to use this form after losing the Hiden Zero-One Driver to Another Zero-One.

ZeroZero-One's version of Rising Hopper has moderately higher stats than Zero-One Rising Hopper in all areas.

However, since the Forceriser was meant to be used by Humagears (specifically MetsubouJinrai.net), transformation with it is painful and Aruto's body experiences a considerable amount of physical strain while using this form. However, he eventually adapts to these drawbacks in battle and manages to defeat Ichi-Gata, who fought on par with Another Zero-One.

This form has three finishers:

• Forceriser finishers:
  • Rising Dystopia (ライジングディストピア, Raijingu Disutōpīā): ZeroZero-One experiences painful shocks of red and black electricity while red mist is released from his body. He is then surrounded by a red energy aura that strengthens him, allowing him to perform attacks and evasive maneuvers at high speeds.
  • Rising Utopia (ライジングユートピア, Raijingu Yūtōpia): ZeroZero-One counters the opponent's punch with a punch of his own, eventually overpowering them and generating a red lightning bolt. He then jumps into the air and performs a flying kick covered in green energy.

This form is exclusive to Kamen Rider: Reiwa The First Generation.

Kamen Rider Zero-Two (仮面ライダーゼロツー, Kamen Raidā Zerotsū) is the primary final form of Zero-One accessed by using the Zero-Two Progrisekey in the Hiden Zero-Two Driver.

Kamen Rider Zero-Two is the culmination of Aruto’s dream of uniting both human and artificial intelligence into one, and has the potential to exceed Kamen Rider Ark Zero’s predictive capabilities. While Zero-Two was conceptualized as a new Kamen Rider of Aruto's own creation, it is also considered to be the final upgrade to the Zero-One system.

Zero-Two's stats surpass Ark-Zero in all areas by a large degree and is superior to all Riders and forms that appear after it, making Zero-Two the strongest Rider form in the series. Zero-Two's most powerful ability is its extreme speed, allowing him to move so fast it appears to the opoonent as though he is teleporting.

Zero-Two can wield the Progrise Hopper Blade and Attache Calibur.

Zero-Two consists of the following parts:

• Zero-Two Head (ゼロツーヘッド, Zerotsū Heddo) - The head.
  • Zero-Two Arithmetic (ゼロツーアリスマテック, Zerotsū Arisumatekku) - Zero-Two's faceplate processor. During the battle, the artificial intelligence Zea extracts the thoughts of the matching person and learns the enemy and surrounding information to predict the behavior. The optimal solution is found in about 0.01 seconds from the 2 trillion patterns of attack and evasion patterns derived from it, and it is reported to the matching person. This ultra-fast learning allows the user to take advantage of the battle.
  • Zero-Two Signal (ゼロツーシグナル, Zerotsū Shigunaru) - The Zero-Two system's control device located between the eyes. It has the role of controlling the signal transmission system, and it makes adjustments to maximize the output of the Zero-Two system by checking matching with matching persons, information transmission loss, defects, etc.
  • Zero-Two Antenna (ゼロツーアンテナ, Zerotsū Antena) - The quantum radar antenna. By introducing a quantum radar that obtains information by utilizing the phenomenon of light, one can avoid electronic interference and invalidate stealth technology and electronic warfare equipment that were previously difficult to detect. This enables information gathering and spatial recognition in all situations and environments.
  • Zero-Two Eyes (ゼロツーアイ, Zerotsū Ai) - The compound eyes. It is a collection of image sensors of different systems in a compound eye shape. By combining with image processing, various information such as thermography and X-ray photography can be extracted. Furthermore, a behavior prediction simulation can be visualized.
  • Zero-Two Mask (ゼロツーマスク, Zerotsū Masuku) - The face armor. Super Positioning Armor, commonly known as "SPA", enables simultaneous operation by stacking two different types of armor. This makes it possible to use the characteristics of either or both of the special metal "Hiden Metal" armor that freely changes hardness, plasticity, and density, and the special armor "Quantum Armor" that the "rider model" has changed. It is possible to prevent all the above attacks.
• Quantum Leaper (クォンタムリーパー, Kwōntamu Rīpā) - Zero-Two's dimensional quantum jump device. This makes it possible to observe the various possibilities that Zea predicts in the real world.
• Quantum Tector (クォンタムテクター, Kwōntamu Tekutā) - Zero-Two's suit. Constructed with a quantum neural network centered on the Zero-Two Driver as the basic equipment to integrate the human body and artificial intelligence. Furthermore, by combining it with a human reinforcement system that applies wave dynamics, each maneuver can be made highly efficient, and theoretically, it will be possible to act at a speed equivalent to the calculation speed of artificial intelligence.
• Zero-Two Streamer (ゼロツーストリーマ, Zerotsū Sutorīma) - Zero-Two's attitude control device. It functions as a photon stabilizer that controls the posture during high-speed activity, etc., by the pressure of lightspeed movement.
• Zero-Two Shoulder (ゼロツーショルダー, Zerotsū Shorudā) - Zero-Two's upper-arm armor. The shape uses quantum engineering to disperse impacts with kinetic energy barriers, negating them by counterpressure. Furthermore, it is equipped with an outlet of the attitude control device "Zero Two Streamer" to control the effects of high-speed movement and enable three-dimensional movement.
• Zero-Two Breast (ゼロツーブレスト, Zerotsū Buresuto) - Zero-Two's chest armor. Super Positioning Armor, commonly known as "SPA", allows simultaneous operation by stacking two different types of armor. This makes it possible to use the characteristics of either or both of the special metal "Hiden Metal" armor that freely changes hardness, plasticity, and density, and the special armor "Quantum Armor" that the "rider model" has changed. It is possible to prevent all upper-body attacks.
• Zero-Two Grabber (ゼロツーグラブ, Zerotsū Gurabu) - Zero-Two's hand and forearm armor. The red armor, which has a metal glass coating made of vitreous Feidin metal on the SPA armor, emphasizes not only improvement of toughness and corrosion resistance, but also improvement of coercive force as a countermeasure against contact with the fluid metal of the Ark. In addition, it is equipped with an "up-puncher", a device that enhances arm strength, and draws out superhuman power from the fitter to demonstrate punch power of 62 tons.
• Zero-Two Stepper (ゼロツーステッパー, Zerotsū Suteppā) - Zero-Two's shin armor. The SPA armor is equipped with a gradual dampening device called the "Step Absorber", which absorbs the impact gradually by the control of Zea to prevent self-destruction due to excessive strain that occurs when performing a greatly enhanced jump or kick.
• Zero-Two Jumper (ゼロツージャンパー, Zerotsū Janpā) - Zero-Two's thigh armor. The SPA armor is equipped with a super jumping device, "Zero Two Jumper", which exerts a jumping power of 200m in a vertical jump by drawing out superhuman power from a suitable person and manipulating the quantum force field. This makes it possible to dramatically improve the destructive power of the kick technique.
• Zero-Two Hopper (ゼロツーホッパー, Zerotsū Hoppā) - Zero-Two's boots. Along with the defense power of SPA armor, the destructive power of the kick has been dramatically improved. In addition, it has high accuracy for pinpointing the attack on the enemy's weakness predicted by Zea. Also, when the deathblow is activated, the kick force of the rider model, which has been consolidated and reconfigured from the previous Hopper rider model, is fully released, creating a tremendous destructive power.

This form has the following finishers:

• Zero-Two Driver finishers:
  • Zero-Two Big Bang (ゼロツービッグバン, Zerotsū Biggu Ban): Zero-Two quickly moves toward the opponent and deflects their attack with an upward kick. He then delivers a horizontal flying kick and lands behind the enemy before performing another upward kick, launching the opponent into the air. Zero-Two follows them and performs a series of aerial high-speed punches and kicks. As the opponent falls back to the ground, Zero-Two performs a final flying kick that produces red and green energy upon impact. The energy is then channeled into Zero-Two's foot before he breaks through the enemy, causing the number "02" to appear before the enemy is consumed by a large red and green explosion.
• Attache Blade finishers:
• Zero-Two Kaban Strash (ゼロツーカバンストラッシュ, Zero Tsū Kaban Sutorasshu): Zero-Two launches a horizontal yellow and red energy slash.

―Transformation announcement^[src]

Rider Statistics:

• Rider Height: 199.9 cm
• Rider Weight: 100.1 kg

Ability Parameters:

• Punching Power: 54.2 t
• Kicking Power: 104.4 t
• Maximum Jump Height: 93.6 m
• Maximum Running Speed: 100 m per 0.6 seconds

Aruto can transform into Kamen Rider Ark-One by using the Ark-One Progrisekey in the Ark Driver-Zero, converting it into the Ark Driver-One. Though Ark-One is primarily the final form of Ark-Zero, it is also classified as an evil form of Zero-One.

Ark-One is still statistically outclassed by Zero-Two by a large margin, as well as Horobi Ark Scorpion. However. his reflexes are heightened, allowing him to dodge and parry multiple attacks, and he possesses some of Zero-One Rising Hopper's agility. He also has unique abilities that Zero-One does not possess, enabling Aruto to defeat all of his former allies. Ark-One is able to poduce shockwaves of malicious energy from his hand, immobilizing multiple opponents, as well as excrete dark liquid from his feet that melts whatever it touches. He can also reprogram A.I-based technology, allowing him to disable the chips implanted in Isamu and Yua that they require to transform.

This form appears to cause Aruto pain, as seen during his first transformation after being given the Ark-One Progrisekey by Azu and later when he is abruptly forced out of transformation after his first fight.

While Ark-One normally fights while unarmed, he briefly wielded the Progrise Hopper Blade during his final fight with Horobi, as well as the numerous Attache Blades scattered around the battlefield.

Kamen Rider Ark-One is composed of the following parts:

• Ark-One Head (アークワンヘッド, Ākuwan Heddo) - The head.
  • Ark-One Face (アークワンフェイス, Ākuwan Feisu) - Ark-One's face armor. It is equipped with an ultra-high-performance antenna and a visual/auditory device that are premised on AI processing. The shape is designed and constructed based on the prediction of psychological effects on the person facing the person.
  • Ark-One Face Ear (アークワンフェイスイヤー, Ākuwan Feisu Iyā) - The voice information collection device. In addition to the auditory sensor that boasts a sound collection range of 10 km in radius, it will collect voice data from communication devices such as mobile phones and AI-equipped devices such as Huma Gear by entering the network. By filtering the collected data, any sound can be extracted and heard.
  • Eclipse Eye (エクリプスアイ, Ekuripusu Ai) - The right compound eye. It is a collection of image sensors of different methods in a compound eye shape. By combining with image processing, various information such as thermography and X-ray photography can be extracted.
  • Ark-One Face Vision (アークワンフェイスビジョン, Ākuwan Feisu Bijon) - The video information collection left eye. By infiltrating the network, it collects video data from reconnaissance satellites, security cameras in the facility, AI-equipped devices such as Humagear. As a result, every place can have its own field of view.
  • Ark-One Face Antennae (アークワンフェイスアンテナ, Ākuwan Feisu Antena) - The antenna. The smart antenna that changes the directivity according to the environment and can simultaneously send and receive a huge amount of multiple types of information, such as communication with various electronic devices and radar functions, is adopted. Hacking to various electronic devices is executed from here.
  • Ark Signal One (アークシグナル ワン, Āku Shigunaru Wan) - The control device for the Ark-One system. By manipulating the EEG, the wearer's non-malicious feelings are calmed down, and the consciousness is focused. In addition, the operating efficiency and malfunctions of the wearer's body are checked, and adjustments are made as needed to bring out the limits of functionality.
• Deus Expite (デウスエクスパイト, Deusu Ekusupaito) - Ark-One's chest armor. It has the function of converting the malicious intent of the wearer into force and generating the "Spite Nega" (スパイトネガ, Supaito Nega) wave of malicious intent. Spite negatives cause explosive destruction by emanating from the red line "Exred Position" (エクスレッドポジション, Ekusureddo Pojishon) across the front.
• Shredding Tector (シュレーディングテクター, Shurēdingu Tekutā) - Ark-One's suit. The liquid metal released from the Ark Driver-One is formed by wrapping up the wearer. Fluid metal is enclosed in a special fabric with excellent toughness and wear resistance, and it functions as armor while maintaining flexibility.
• Ark-One Shoulder (アークワンショルダー, Ākuwan Shorudā) - Ark-One's upper-arm armor. The fluid metal, which is the main material for the armor, transforms into a sharp shape called "Spite Edge" (スパイトエッジ, Supaito Ejji) by temporarily increasing hardness and density and becomes a piercing weapon.
• Ergonice Arm (エルゴニースアーム, Erugonīsu Āmu) - Ark-One's arms. The power cable "M string" (Mストリング, M Sutoringu) of the powered suit "Shredding Tector" is stretched around like a human nerve, and reinforces the movement of the wearer from the outside. At the same time, by injecting the energy supplied from the Ark Driver-One, the wearer is given the power to destroy the target.
• Ark-One Gauntlet (アークワンガントレット, Ākuwan Gantoretto) - Ark-One's hand and forearm armor. The sharp armor of the fingertips "Spite Nail" (スパイトネイル, Supaito Neiru) uses the barrier developed from the Ark-One Cuis on the thigh, and manipulates the repulsive force and attractive force on the target to deprive everything of freedom. In addition, the irradiation shaping machine "Beam Equipper" (ビームエクイッパー, Bīmu Ekuippā) is equipped on the palm, and in addition to materializing various data such as attach weapons with a modeling beam, it also functions as an irradiation port for the "Spite Nega".
• Ark-One Cuisses (アークワンキュイス, Ākuwan Kyuisu) - Ark-One's thigh armor. The "Coulomb Generator" (クーロンジェネレーター, Kūron Jenerētā) is built in and forms a coulomb barrier generated by manipulating electric charges on the armored surface of the whole body. This allows the physical attack to be dispelled by repulsive force.
• Ark-One Greaves (アークワングリーブ, Ākuwan Gurību) - Ark-One's shin armor. By using the barrier developed from the Ark-One Quiz on the thighs, the repulsive force and attractive force applied to itself can be manipulated to enable floating in the air and maneuver speed.
• Ark-One Sabaton (アークワンサバトン, Ākuwan Sabaton) - Ark-One's boots. When the Special Move is activated, by expanding the anti-annihilation field, it is possible to convert the substance that becomes a resistance or obstacle into energy. This nullifies the physical defenses and at the same time improves the destructive power of the kick.

Ark Driver finishers:

• Perfect Conclusion (パーフェクト・コンクルージョン, Pāfekuto Konkurūjon):
  • Perfect Conclusion: Learning 5 (パーフェクト・コンクルージョン: ラーニング5, Pāfekuto Konkurūjon: Rāningu Faibu): Ark-One's body is surrounded by malicious kanji and yellow electricity before generating two large "wings" of crimson energy. Ark-One then absorbs the energy into his body and projects a red energy field around him. Finally, an explosion destroys anything within the bounds of the energy field and damages anyone nearby.
  • Perfect Conclusion: Learning End (パーフェクト・コンクルージョン: ラーニング　エンド, Pāfekuto Konkurūjon: Rāningu Endo): Ark-One jumps into the air and delivers a flying kick covered in red and black energy. Additional black energy is then channeled into his foot just before he strikes the enemy.

Progrise Hopper Blade finishers:

• Final Strash (ファイナルストラッシュ, Fainaru Sutorasshu): Ark-One swings the Progrise Hopper Blade, launching a jagged construct of Cluster Cells at the enemy.

Soreo Hiden-AlternateTimeline.png

Soreo Hiden (Humagear)
Surrogate father (destroyed)

• Korenosuke Hiden: Aruto's grandfather. As an adult, Aruto inherits Hiden Intelligence from him. Korenosuke also entrusted Aruto with the patent rights and any and all related data pertaining to the Humagear system and the Zero-One Driver, because he believed that Aruto will lead the Humagears to prosperity.
• Soreo Hiden/Kamen Rider Ichigata: Aruto's father. Aruto says that Soreo died when he was very young, so a Humagear taking on Soreo's likeness was created to raise Aruto. The Humagear later broke beyond repair while protecting a young Aruto during the Daybreak Town Accident, an event that would greatly impact Aruto's positive view on the Humagears as he grew older.

• Yoshino Hiden - Mother (deceased) ^{[The End of Each]}
• Ichiko Hiden - Grandmother (deceased) ^{[The End of Each]}

Allies

• Hiden Intelligence
  • Izu: Since Aruto becomes the new CEO of Hiden Intelligence, Izu serves him as his secretary. Izu provides Aruto with her vast knowledge of anything related to Humagears and Hiden Intelligence, and they get along well. Aruto was initially bewildered if Izu tries to explain his lame jokes or even copying it, but now he seems to get used to it. Aruto views Izu more than as a Secretary. As shown when Aruto refuses to replace Izu with another Humagear and desperately tries to fix Izu. In return, Izu is deeply devoted to Aruto and provides invaluable help (such as personally delivering new Progrisekeys/Weapon) during battles. Izu's loyalty to Aruto doesn't waver even after reaching Singularity and together they created HIDEN Manufacturing after Aruto loses his position as the CEO of HIDEN Intelligence. It's later shown that Izu loyalty turns into affection as time passes, as shown where she couldn't withstand the many simulation of Aruto’s death to the point that she openly cries in front of Jin. Aruto also starts to care about Izu like a family. As shown after Izu's death at the hands of Horobi, it sends Aruto into a level of despair, he willingly becomes Ark-One to enact revenge for her death. After the final battle with Horobi, Aruto recreated Izu, despite knowing that she didn't have her previous memories before getting destroyed.
  • Jun Fukuzoe: After Aruto was appointed as the new CEO of Hiden Intelligence, Jun becomes bitter and possessed a Inferiority Complex toward him. He even declares that Aruto had to step down from the CEO position immediately after the Kuehneo Magia rampage. Despite that, Aruto manages to somehow outsmart him by showing proof that MetsubouJinrai.net was the culprit behind Magia rampages, much to Jun's dismay. From that point, Jun, along with Sanzo secretly wishes for Aruto to fail. This animosity and inferiority also shown when Jun didn't hesitate to physically abuse Aruto, and coldly coerces Aruto to replace Izu with a new Humagear. However, despite his hostility to Aruto, he will not hesitate to follow him if it benefits the company. He was also willing, albeit reluctantly, to give Aruto praise for his actions to protect Hiden Intelligence from Metsuboujinrai.NET, claiming he knows when to give credit when it is due. Ultimately, following the Workplace Competition resulting in Gai's victory, Jun admitted that he held no ill will against the young CEO, even expressing concern for him, questioning what would he do next. After asking Aruto to help him out Gai from his seat, Jun re-affirmed Aruto's love for Humagears, encouraging him to take the fight to Ark after his first defeat against it. After Gai resigned as the CEO of Hiden Intelligence and Aruto reinstated as the CEO once more, Jun welcomes him with open hand and become more willing to cooperate with him.
• Isamu Fuwa/Kamen Rider Vulcan: They both also have polar opposite views towards Humagears. While Aruto views Humagears as people who will help achieve humanity's dreams, Isamu views Humagears as the enemy of humanity and even sees Hiden Intelligence to be real culprits behind the Daybreak Town Accident. However, Isamu is one of the very few people who find Aruto's lame jokes funny. After Aruto personally transforms into Zero-One in front of Isamu (despite Izu’s objections), his animosity towards the young CEO is lessened greatly. Despite this lessening animosity, the two still argue on how they view Humagears. Throughout the events of ZAIA, filled with confusion of his ideals of Humagears, Isamu encouraged him not to give up on them regardless of the Ark's doings. Eventually, Isamu begin to accept Humagears as long as they are not malicious, and actively helps Aruto as a trustworthy ally during battle.
• Yua Yaiba/Kamen Rider Valkyrie: Aruto and Yua first meet during A.I.M.S. visit to Hiden Intelligence, and meet again at a sushi restaurant. Aruto was impressed by Yua since she was seemingly more adapted and civil with Humagears, although after Nigiro turned into a Trilobite Magia, Yua showed disdain and exclaimed that Humagears are just mere tools, a statement to which Aruto expressed much disagreement. Yua also secretly monitors Aruto for reasons related to the Daybreak Town Accident. After Yua left A.I.M.S. and rejoining ZAIA Japan, Yua become much colder towards the CEO. Yua keeps helping Gai during the workplace competition as his secretary/assistant, despite fully knowing Gai's underhanded tactics, she's powerless to even object Gai's decision due to the fear that her A.I. chip would be tinkered by her boss, just like how Gai manages to tinker Isamu chip with Naki's data. After Yua resigns from ZAIA, Aruto & Yua remained civil to each other.
• Wazu Nazotoku: A detective who also served under Aruto's grandfather and Izu's older brother. He offers his help in clearing the company's innocence and later sacrifices himself to complete the Shining Hopper Progrisekey to its full potential.
• Jin: Aruto first meets Jin after he transforms Mamoru into the Ekal Magia. Jin declares himself as the new ruler of the world, much to Aruto's anger. Aruto actually tries to reason with Jin after the latter damages Izu, arguing on why a Humagear like him decides to slaughter Humanity. However, seeing that Jin is beyond redemption, Aruto finally destroys him as Zero One Shining Assault Hopper. After being rebuilt by unknown means, Aruto manages to convince Jin to save Humagears together from Gai Amatsu, thus Jin decides to form a truce with the young CEO since they have the same interest and ironically, the same enemy, despite that, it has been shown that Jin does not yet trust Aruto, wanting to take away the data he has from the Humagears at any cost. However, Jin had also decided to help Aruto in a different manner- the destruction of the Ark A.I. After failing twice and being possessed, he tried to protect Aruto from the Ark, even stealing data from his former leader. After Aruto fell to malice and became Ark-One, Jin sacrificed himself to protect Horobi. When Aruto realized what he had done to Jin, the grief of killing someone he considered a friend overwhelmed him, and Aruto fled the scene.
• Gai Amatsu/Kamen Rider Thouser: As a fellow company CEO and rival, Aruto displayed a level of respect towards Gai, referring to him as "President Amatsu" during the course of the Workplace Competition. Not knowing how much Gai despised the Hiden family, Aruto went through the competition with fairness and honesty, something Gai did not uphold several times. After learning of Gai's true nature and his past regarding the Ark, Aruto lost all respect for him and swore to defeat him no matter the cost. However, Aruto decides to help Gai regain his compassionate personality after Ark fully revives by leaving Ai-chan to Gai to settle his inner demon. Gai finally decides to change for good to the point that the two CEO's cooperated to defeat Ark-Zero. Later Gai decides to apologize to Aruto for his past misdeeds, however Aruto demands Gai to atone for his sins by using his actions.
• Horobi: Aruto directly confronts Horobi after Little Assassin successfully assassinates Shinya Owada, thus changing the drama production views towards Humagears. Aruto himself declares that he'll never forgive Horobi for his heinous acts. However, after Aruto discovered that the Ark was responsible for creating such a malicious nature in MetsubouJinrai.net, he focused all of his anger and hatred onto Gai instead, and took a much more sympathetic route for Horobi, eventually supporting him in finding his dreams. However, after being freed from the Ark, Horobi continues his dream of humankind's extinction, reasoning that as long as humanity malice existed, it'll allow Ark to revive again. His first step to achieving that dream is killing Izu in front of Aruto (although he seems reluctant to do so), to which Aruto becomes fueled by revenge, becoming enemies once again in the process. Ultimately, during final battle Aruto revealed a continuous usage of Ark-One Driver had a purpose: to teach Horobi about heart's being. After final battle their relationship surely took a better turn.
• Naki: Aruto first know about Naki after they possesses Isamu. Aruto then confronts Naki and tells them to find their dreams.
• Ikazuchi: Aruto first knows Ikazuchi as Uchuyaro Raiden, an astronaut Humagear that works to maintain Zea. Aruto refers Raiden as Big Brother (兄貴, Aniki) due to his down-to-earth approach to him. After Raiden was identified by Jin as a Metsuboujinrai sleeper agent named Ikazuchi, Aruto reluctantly views him as an enemy. After Ikazuchi's revival and his subsequent recovery of his memories as Raiden, Aruto calls him "Aniki" once more, although in the end he was unknowingly used by Ark to hack Zea.

Enemies

• Ark: Aruto has a horrible impression of the Ark, due to the events throughout the series that were caused by it. After it revived, the Ark referred to Aruto as "Korenosuke's grandson". Aruto ended up creating and transforming into Zero-Two to defeat the rogue satellite, but he became the Ark itself to avenge Izu in a twist of irony.
• Azu: Aruto initially saw Azu as Izu until she revealed her true identity. After falling into despair, Azu influenced Aruto to become Ark-One, and began referring to him as "Master Ark". Aruto seems to not care about Azu at all as he insisted that Izu is his one and only secretary for him. He also showed a visible amount of annoyance with Azu's cunning and playful antics.
• Lyon Arkland: Although they never met, Arkland is aware of Aruto's existence and states that he opposes Zero-One and wants to destroy him once for all. In contrast to Aruto's beliefs, Lyon serves as his complete opposite.

Notes

Zero-Two's energy muffler

• Being the first Kamen Rider of the Reiwa period, Zero-One's name and motif are in homage to Kamen Rider 1. He is the first lead Kamen Rider to have a grasshopper as his central signature design motif since Kamen Rider Black RX, and returning to the traditional insectoid eye design since Kamen Rider Fourze (discounting Amazon Omega and Amazon Alpha). The circular design in the center of the Hiden Zero-One Driver is a possible homage to the Typhoon and most Showa era belts.
  • Kamen Rider Zero-Two is a homage to Kamen Rider 2, due to their similar naming, Zero-Two's red forearms corresponding to Kamen Rider 2's gloves, and Zero-Two being shown in a pose similar to 2's signature transformation pose in promotional material.
    • Similar to Ichi-Gata, Zero-Two gains an energy muffler whenever it uses its finisher as a homage to Kamen Rider 2's trademark scarf.
    • Kamen Rider Zero-Two naturally has the highest stats compared to the rest of the Zero-One forms. On that note, Kamen Rider 2's physical statistics are stronger compared to Kamen Rider 1, which earned him the title of "Power of 2" (力の２号, Chikara no Nigō).
  • Aruto's transformation into Kamen Rider Ark-One seems to further solidify this homage, as the Ark-Driver One, having a mainly white body and a red core, bears a greater resemblance to the Typhoon, as well as the Arcle, the first transformation belt of the Heisei era.
• Zero-One's signature pose is nearly identical to Kamen Rider Kuuga's signature pose.
• According to the first episode, Aruto is 22 years old. However, his actor, Fumiya Takahashi, was 18 years old at the time.
  • Aruto's 22nd birthday fell on the first day of the Reiwa era.
• Kamen Rider ZeroZero-One's suit reuses the chest armor of Horobi/Jin, the undersuit, leg armor and abdominal armor of Night Rogue, the shoulders and the armor on the arms from the Nebula Hell Bro's. The only original elements are the helmet and Restrain Cables added to the thighs.
  • The much later Hellrising Hopper is a recolored Shining Assault Hopper with a modified chestplate and more pronounced trapezoidal armor, fitting as both forms rely on elements that cause the armor to physically emerge from within the undersuit.
• Kamen Rider ZeroZero-One strongly parallels Kamen Rider Super Dead Heat Drive, both being makeshift forms that the protagonist Riders are forced to access via an alternative transformation device due to losing access to their primary transformation gear, resulting in a form that repurposes villains' suits as a dark version of the main Rider, and slightly changing the proper name of the Rider.
  • ZeroZero-One's name is also a nod to the codenames of the 00 Cyborgs from Shotaro Ishinomori's Cyborg 009 and even shares the name with Ivan Whisky/Cyborg 001 from the same manga.
• Aruto is the only user of the MetsubouJinrai Forceriser who is not affiliated with MetsubouJinrai.net. He is also the only human to have done so.
• Aruto is the second Rider to use a kangaroo-based form since Kamen Rider OOO.
  • In both cases said forms were exclusive to their Hyper Battle DVDS.
• While never explicitly stated, Aruto may or may not be a byproduct of his Over Quartzer counterpart's existence, due to their identical voice and powers.

Concept Names for Zero-Two

• During the creation of Zero-Two System, Aruto came up with some concept names for his new Kamen Rider before he named it as Kamen Rider Zero-Two:
  • Kamen Rider Super Zero-One (仮面ライダースーパーゼロワン, Kamen raidāsūpāzerowan) (Possibly a homage to Kamen Rider Super-1)
  • Kamen Rider 0001 (仮面ライダー0001[ゼロゼロゼロワン], Kamen Raidā Zerozerozerowan) (Homage to Kamen Rider ZeroZero-One)
  • Kamen Rider Hyper-One (仮面ライダーハイパーワン, Kamen Raidā Haipāwan)
  • Kamen Rider NEW Zero-One (仮面ライダーNEWゼロワン, Kamen Raidā Nyū zerowan) (Possibly a homage to Skyrider's original series name "New Kamen Rider")
  • Kamen Rider Strong-One (仮面ライダーストロングワン, Kamen Raidā Sutoronguwan) (Possibly a homage to Kamen Rider Stronger)
• As of Episode 42, Aruto has transformed into a grand total of four Kamen Riders (Kamen Riders Zero-One, ZeroZero-One, Zero-Two, and Ark-One), beating Yuji Kiba's previous record of three (Kamen Riders Faiz, Kaixa, and Orga). As such, Aruto is the only Rider in the series to be granted a different Rider name for each Driver he has used, and the only main Rider in the franchise to hold such a distinction.
  • Similar instances in the past have either added an extra phrase before (e.g. Super Dead Heat Drive) or after (e.g. Ryuki Survive) of their standard name, or, in the case of Kamen Rider Black RX, the different Drivers are actually all variations of the same transformation device.
• Ark-One's chest resembles the ZAIA Spec, and by extension the Ark Spec found in the Ark-One Progrisekey.
• Before becoming Kamen Rider Ark-One, there were several instances of Aruto using the Ark's power over the course of the series.
  • In Kamen Rider Reiwa: The First Generation, Aruto was forced to use a MetsubouJinrai Forceriser, an equipment typically used by high-ranking members of MetsubouJinrai.net, while this Forceriser connects to the Ark safely without being corrupted.
  • Over the course of the series, Aruto upgraded his arsenal with the Ark's power and technology. First, he used the Assault Grip, which was created by the Ark, and was used to upgrade the Shining Hopper form. Then he was forcibly given the MetalCluster Hopper Progrisekey, giving Aruto a direct connection to the Ark and temporarily causing the Zero-One System to go berserk.
  • It was during the Workplace Competition arc where it is demonstrated that both Humagears and humans can transform into the Magia & Raiders respectively when coming under the influence of the Ark.
• Zero-One is the first Reiwa Rider to use an Extra Final Form in the finale of his series.
  • To an extent, he is the third titular Rider who use an Extra Final Form in the finale of his series (Realizing Hopper), with the first and second being Kamen Rider Build (RabbitDragon Form) and Kamen Rider Zi-O (Kamen Rider Ohma Zi-O) respectively.
• Amusingly, Zero-Two is the most powerful Kamen Rider by statistics in the Kamen Rider Zero-One series, including movies and spin-offs. Even when new Kamen Riders and forms debut after Zero-Two such as Ark-One, Ark-Scorpion, Eden, and even Hellrising Hopper, Zero-Two's statistics are at a much higher magnitude compared to all of them.
  • Zero-Two losing to Eden is due to Eden's regenerative nanomachines, so it could not be defeated by conventional means. MetalCluster Hopper's Cluster Cells and Hellrising Hopper's explosive power were much more fitted for attacking Eden's specialized physiology.
