"I'm just a passing-through Kamen Rider. Remember that!"
―Tsukasa's answer when asked who he is[src]

"This might tickle a bit."
―Tsukasa's warning before using a Final Form Ride Card on a Legend Rider for the first time.[src]

"I... am watching to see if this world should be destroyed or not. If all I see is Sougo Tokiwa becoming the demon king in the future... then the answer is obvious."
―Tsukasa Kadoya to Tsukuyomi[src]

Tsukasa Kadoya (門矢 士, Kadoya Tsukasa) is the main protagonist of Kamen Rider Decade. He is an inter-dimensional traveler who transforms into Kamen Rider Decade (仮面ライダーディケイド, Kamen Raidā Dikeido, Masked Rider Decade) to exercise his role as The Destroyer of Worlds (世界の破壊者, Sekai no Hakaisha). As the overseer of the A.R. Worlds, he travels to each one to determine whenever it warrants destruction. Tsukasa continued his exploits across the Rider multiverse in Kamen Rider Zi-O as he observes the actions of Sougo Tokiwa.

History

Background

Ten years ago, Tsukasa Kadoya had lost his parents at a young age, leaving him and his younger sister Sayo Kadoya in the custody of his family's butler, Nobuhiko Tsukikage. Sayo feared going outside, which manifested the ability to open Aurora Curtains. Tsukasa would exploit these abilities to explore different worlds, which upset his sister who was left in her room in their home reality.

Before long, Tsukasa discovered that he possessed the same power to manipulate Aurora Curtains and began traveling alone to other worlds. At an unspecific time during his teens, he was appointed as the "Great Leader of Dai-Shocker" (大ショッカー大首領, Dai Shokkā Dai Shuryō) and acquired the Decadriver and Ride Booker. Using his position and power, he began his conquest across different dimensions, which would become known as "A.R. Worlds".

However, after one year into his campaign, Tsukasa suffered from amnesia caused by turbulence while traveling between numerous dimensions and stranded in an unknown peaceful world. While wandering in the unknown world, Tsukasa began to take pictures at Hikari Studio, where he met Natsumi Hikari. However, the images he captures on his camera would be distorted and not develop well due to his status as an outsider of the world.

Becoming Kamen Rider Decade

One day, Tsukasa is scolded by Natsumi over the distorted photos he had captured. While he laments for being unable to recall his past, he and Natsumi are separated by an Aurora Curtain. Tsukasa is transported to a pocket dimension where he encounters Wataru Kurenai, who addresses him as "Decade" and states that the world is ending and that Tsukasa must protect it. After reuniting with Natsumi, Tsukasa notices the Decadriver in her possession and uses it to transform into Kamen Rider Decade. Using the power of the Rider Cards, he transforms into Kamen Riders Kabuto, Faiz, and Hibiki to combat against the horde of Worm, Orphnoch, and Makamou. Confused by the ordeal, Tsukasa and Natsumi find her world besieged by monsters. Wataru reveals her world's destruction is a result of the Nine Worlds converging into one world. Tsukasa would be given the task to traveling to these worlds to seek out the Kamen Riders and resolve the disturbances in each world.

Traveling Through The Nine Worlds

Starting in the World of Kuuga as a police officer, Tsukasa meets the world's Rider, Yusuke Onodera who battles the Gurongi and learns that someone is disseminating rumors across the Worlds about him as the Destroyer of Worlds. After reconciling with Yusuke, the two stop the Gurongi N·Gamio·Zeda from taking over the world. Tsukasa would motivate Yusuke to not fight for the smiles of one person, but for the smiles of everyone.

At the World of Kiva as a violinist, Tsukasa encounters the young boy Wataru, helping the boy realize his role as King of the Fangire Race to maintain the peaceful coexistence of the human and Fangire races while defeating the Beetle Fangire: Wataru's father and the former King. Tsukasa would also reunite with Yusuke, who decided to follow him in his journey, and they motivate Wataru to accept himself as a human and Fangire hybrid.

Then at the World of Ryuki, Tsukasa defends the framed Natsumi in a murder case and solves it with the aid of Shinji Tatsumi. The true villain, Kamata is revealed to have been an Undead all along and is taken by Narutaki to the World of Blade after his defeat.

Assuming the role of chief waiter under the BOARD Corporation while being promoted repeatedly, Tsukasa works with Kazuma Kendate to uncover the conspiracy between Kamata and BOARD's CEO, Kamen Rider Chalice, to take over the world through the Joker card which the latter used on himself. After he and Blade work together to defeat the Undead, Tsukasa takes his leave as Kazuma thanks him.

In the World of Faiz as a student of the Smart Brain High School, Tsukasa crosses paths with a man he saw at the World of Blade who knows him, Daiki Kaito. Though Kaito warns him to stay out of his affairs, Tsukasa finds Faiz after confronting the Lucky Clover group, learning that he is Takumi Ogami as he attempts to keep his SB-555B Faiz Driver away from Kaito. Tsukasa later resolves the tension between Takumi and Yuri Tomoda over Takumi's identity, giving Takumi the will to continue protecting the school.

Arriving in the World of Agito as a postman, Tsukasa reads a discarded letter meant for Shoichi Ashikawa, making it his goal to protect Ashikawa from the Unknown for the sake of Tohko Yashiro, the writer of the letter. With Yusuke's help, Tsukasa succeeds in having Shouichi achieve the necessary state of mind needed to complete his evolution to Kamen Rider Agito before reuniting him with Yashiro.

Upon arriving in the World of Den-O, Tsukasa becomes Den-O under the possession of an Momotaros, before forcing him into Yusuke's body. Here, he learns that some unknown force is changing the past as he is fought by the other Taros possessing Natsumi's body who believe Decade to be the source. Tsukasa finds Momotaros and helps him regain his physical form as they defeat the Alligator Imagin.

In a ZECTrooper role, after witnessing TheBee and Gattack's fight against a Worm, Tsukasa brings Arata to the photo studio where he finds a Salis Worm that had mimicked him. After the impostor is exposed, the Worm is killed by Kabuto when it attempted to kill a girl named Mayu whose brother was believed to have been killed by Kabuto. Although it seemed that TheBee's user, Soh Otogiri, is her brother, Tsukasa felt something was not right. He learns of Mayu's true nature as a Worm, both his meeting with her grandmother and learning the full nature of the Kabuto Capture Plan. Tsukasa arrives to Mayu's aid and helps Kabuto, Mayu's real brother Sohji, in defeating Otogiri in his true form, the Phylloxera Worm. After bringing Mayu back to her grandmother, he giving Daiki a vial of pepper as a "treasure".

In the World of Hibiki, Tsukasa meets and encounters an Oni in training named Asumu. From there, believed to be the Great Master of Ongekidō style, Tsukasa meets the three masters of the Ongekidō Styles before being pulled into a ploy by Daiki to rob the two Oni masters Ibuki and Zanki, worsening when they are attacked by the Makamou Gyuki until Akira and Todoroki drive the beast off. Supporting their intent to end the rivalry among their schools, Tsukasa convinces Ibuki and Zanki to pass the torch. Tsukasa later offers his aid to Asumu after he became the new Hibiki thanks to Daiki, whom he still acknowledged as a thief and nothing more.

Going For The New Worlds

With the journey over, Tsukasa and the others of the Hikari Studio return to what appears to be Natsumi's world to find it back to normal as if it was not plagued by the monsters. Despite being in a perfect world that he has earned, according to Otoya Kurenai, it is revealed that it is only a parallel version of their own world where the monsters have taken over and killed all but a few humans. After being tested by Otoya, Tsukasa gains the K-Touch after turning down Otoya's offer to live in a world of lies, using Decade's Complete Form to defeat the Dark Riders.

Arriving in the World of Diend, he finds himself in the role of a salary man selling products to the society until he encounters Shin and Haruka, Kamen Riders Lance and Larc, fighting a Darkroachi. He uncovers Daiki's past regarding his former alligence with Fourteen, who brainwashed the inhabitants of his homeworld and how the Kamen Riders are branded as criminals. He and Daiki team up to defeat Fourteen to free all those who have been brainwashed, leaving only Daiki's brother Junichi, Kamen Rider Glaive, who was not brainwashed but accepting of Fourteen's peaceful world. He teaches the two brothers that they have to protect each other, no matter what, before heading off to the next world, one which he has no knowledge of at all.

In the guise of a kuroko with a strange card in hand, Tsukasa learns that his lack of knowledge is due to the world not having any Kamen Riders as he witnesses the ShinkengersIcon-crosswiki.png drive off the Nanashi. Curious about them, Tsukasa uses his guise to learn more about them and their world before fighting the Ayakashi Chinomanako who stole the Diendriver from Daiki. He realizes that the monster is the reason why he is in this world as Chinomanako becomes the world's first Kamen Rider. He attempts to fight the Chinomanako but is stopped by Narutaki saying that his actions will only bring doom to the world. After being given the advice to do the right thing by Hikoma KusakabeIcon-crosswiki.png, Decade later helps the Shinkengers with the card revealing to be the Rekka Daizantou which he uses to destroy Chinomanako alongside Shinken RedIcon-crosswiki.png using the Blade Blade. As Tsukasa and Yusuke are welcomed back by Eijiro and Natsumi, assuring Tsukasa that the photo studio is his home no matter what.

Entering the World of Black RX, receiving another card and being mistaken as Joe the Haze when he changes clothes, Tsukasa is attacked by Shvarian and his Chap minions while meeting Kamen Rider Black RX, Kohtaro Minami. Decade then finds out that Dai-Shocker is in this world planning to conquer it. Decade teams up with RX to help fend off the assault on this world. Eventually, the Security Chief of Dai-Shocker, Apollogeist drains Natsumi's life through his Perfector ending up in a hospital and Tsukasa desperate to revive her. Decade learns of Apollogeist and the Perfector from Kaito and goes off to find him, but Kaito also has his agenda of retrieving the device. Decade, with assistance from RX, battles Apollogeist but falls into a Aurora Curtain.

Arriving in a different world, he encounters the Kotaro Minami of that world, who transforms into Kamen Rider Black. Decade is attacked and refuses to fight, only to be aided by Diend. They retreat and Decade continues his search for Apollogeist. After saving a child, Decade managed to gain Black's trust in the process and teamed up with him. They come across Apollogeist and Tsukasa is able to get back to RX's world with Black's assistance. Confronting Apollogeist once more, Diend takes the Kamen Rider Black card to summon the Rider to RX's world. Two Kotaros transform and fight Apollogeist and Decade is able to get his Perfecter, but Diend steals it and runs away. At the hospital Kaito hands over the Perfecter, in order to give part of his life into Natsumi and reviving her. Before leaving, Tsukasa tells Kotaro that Joe the Haze is helping his counterpart. But Kotaro is not saddened by it, knowing that Joe will be with him in spirit.

When Tsukasa enters the World of Amazon assumes the mantle of a baseball player and receives yet another card. He immediately sees that Dai-Shocker has taken over this world and is attacked by some of the monsters from different worlds. Amazon appears suddenly and helps Decade fight them, but forced to retreat as even the civillians rushed in to protect the Dai-Shocker forces. He also reunites with Apollogeist who demands him to return his Perfector, but Decade destroys it instead. After a boy named Masahiko stole Amazon's GiGi armlet, Tsukasa helps retrieve the armlet back and save Masahiko. Decade fights alongside Amazon to defeat the ruler of the world, Jyumenki Yum Cimil. Amazon is then adopted into Masahiko's family and the gang returns to the photo studio to find Diend sitting there and he proposes that he go with them.

World of the Rider War

Tsukasa arrives into the final world, where all the Kamen Riders are supposed to be; "World of the Rider War". It is the same place that Natsumi saw when she had her dream about the war. The World of the Rider War is Decade's undoing as he witnesses both Kazuma Kendate and Wataru leading an army of Riders and monsters against each other. Tsukasa and Yusuke try to keep both sides from killing each other and find that the Fangire Queen, Yuki, has married Apollogeist, evolving into Super Apollogeist. With this new enemy, Tsukasa destroys Yuki and the rest of the Fangire and Undead armies with help from Kazuma Kendate and Wataru. Unfortunately, Super Apollogeist accelerated the fusion of worlds, causing Kazuma and Garren to disappear and Apollogeist kidnaps Natsumi.

Decade Complete Form uses the Attack Ride of Diend.

"Come get me if you dare! I’ll destroy you all!"
―Tsukasa accepting his fate as Destroyer of Worlds and beginning The Rider War[src]

Tsukasa is then confronted by the original Kamen Rider Blade, Kazuma Kenzaki. Decade finally finds out why the worlds are merging and it is because of Decade's nature to unintentionally bridge worlds by entering them. Decade is quickly defeated by Blade King Form and forced to withdraw. After returning to the photo studio in poor condition, Tsukasa finds out every picture he took in the other worlds are completely blank because they are nearly gone. Decade heads out to follow Kiva-la and is confronted by Hibiki and Kiva who are forced to fight him. Kuuga saves Decade while he deals with Apollogeist. As Apollogeist brought back the previous monsters he fought in the different worlds, Decade fights alongside Diend and Kuuga, as well as Kiva and Hibiki to finally vanquish Apollogeist and his monster army.

Although their battle ended in victory, Kiva and Hibiki finally fading away because their worlds no longer exist. Decade is taken to the place where it all started the place where he met the original Wataru Kurenai. Wataru explains that Tsukasa discovered messed up his job and says that the Kamen Riders will fight him as he transforms into Kamen Rider Kiva. Decade is transported back into the battlefield where original Kamen Riders appear and Kuuga becoming Ultimate Form to fight Decade. With that the Rider War begins.

Decade's Final Chapter

"The answer is simple. I am the destroyer of all. I have accepted that."
―His answer when Natsumi confronts him about him accepting what others used to gossip about him.[src]

Kamen Rider Decade Violent Emotion.

In Decade: Final Chapter, despite being unwillingly the Destroyer of Worlds, Tsukasa accepted his role and turns into Violent Emotion Decade, destroying all Riders and began turning them into cards. He was assisted by Yuriko Misaki who could transform into Electronic Wave Humanoid Tackle. He was later confronted by Natsumi who has become Kamen Rider Kiva-la to stop his rampage. Before Tsukasa died, after voluntarily letting her kill him and gave Natsumi the Kamen Ride Cards so that as long as people remember the Kamen Riders they would never disappear.

Natsumi and Kaito learned from Wataru Kurenai of Decade's role as the destroyer and connector of worlds, as Tsukasa would destroy the Riders he would connect the other worlds preventing their collapse and does anything he was needed for as a hero or a villain to finish the Rider's story. He himself however had no story and with his task complete Decade was gone forever. Despite this, Natsumi found a way to revive him through the use of a picture and the A.R. Riders' memories, and Tsukasa was resurrected. Tsukasa and the gang along with other Riders fought against Super Shocker receiving more help from Kamen Rider Double whom he met in his summer movie. With Double's Final Form Ride, he and Double destroyed Ultimate-D. He was last seen with his friends posing for a picture after the battle while continuing his adventures across the A.R. Worlds.

Birth Of Zi-O

Tsukasa Kadoya arrived to Zi-O's world presumably before the events of the series upon discovering irregular time distortions which were caused by Swartz and the Time Jackers, in which he allied himself with them to discover the origins of the distortions.

"You want to become a king, right? But, that will never happen. I will destroy this world before you will."
―Tsukasa's warning to Sougo Tokiwa[src]

Frustrated by Sougo Tokiwa's insistence upon befriending Geiz Myokoin, Woz allied himself with the Time Jackers and introduced them to Tsukasa, calling him a potential rival to Zi-O's reign but also a very capricious man. He first appeared using the power of Kamen Rider Agito to prevent Takeru Tenkuuji from catching Another Ghost. The next day, Tsukasa again intervened to protect Another Ghost from Geiz. Decade intervened again the next day during Zi-O and Geiz's fight against Another Ghost by transfroming into Kamen Rider Hibiki. Elsewhere, Ora then asks Tsukasa if he desires to be a king, in which Tsukasa is not interested. It is then revealed that Tsukasa already has the Decade Ridewatch.

Tsukasa was back in action as Ora asked him to prevent Geiz from defeating Another Ghost. He used an Aurora Curtain to travel to 2015 and stop Geiz as Kamen Rider Ryuki and later Kamen Rider Ghost. After defeating Geiz, he took his Ghost Ridewatch and nullified it into a Blank Ridewatch. But for an unknown reason, he passes on his Decade Ridewatch to Geiz with "an exchange". During the final fight against Another Ghost, Tsukasa only watched the fight having understood Sougo enough. Tsukasa is also both confused and agitated by Woz's celebration announcement, even taking away his Ohma Advent Calendar to silence him. That night after the fight, Tsukasa came to 9 5 DO, eating Sougo's dinner. He introduced himself to Junichiro, Tsukuyomi, and Sougo and takes a photo of Sougo. Before he leaves, Tsukasa proceeds to tell Sougo that it's impossible for him to become the Demon King as he intends destroy the world before Sougo even became one.

During the battle against Kasshine, Tsukasa reveals himself to Sougo as both transform into their Rider forms. During the battle, Decade transforms into Kamen Rider Build as Zi-O transforms into DecadeArmor Build Form. Decade tells Sougo to go to the Year 2068 by using a Aurora Curtain to see Sougo's future self, Ohma Zi-O.

Decade joins Kasshine in a battle against Zi-O and Geiz. During the battle, Decade transforms into Kamen Rider Wizard to counter Geiz in WizardArmor. As Zi-O and Geiz are fighting Kasshine, Decade suddenly leaves the scene.

Investigating Sougo Tokiwa's Past

Tsukasa investigates in the year 2009 as a bus driver, that transported a young Sougo Tokiwa and Hiryu Kakogawa. After Swartz causes the bus to go out of control and escapes with the children, Tsukasa escapes through a Aurora Curtain with Tsukuyomi from the exploding bus.

From there, they were transported to the near future where a Dai Mazine is destroying the city and they witness Swartz select the young Sougo as a candidate to be king. Tsukasa then explains to Tsukuyomi that his objective is to observe all the happenings, and whether he'll fulfill his role to destroy this world.

Space-Time Distortion

With the appearance of Ginga and Kamen Riders appearing alongside their Another Rider counterparts due to a fracture in the space-time continuum, Tsukasa steps in to investigate. He reveals to Swartz that he sees a connection between his and Tsukuyomi's pasts, and is determined to prove it. He brings Tsukuyomi to the year 2058 where they meet her younger self in her residence. They were both ordered to leave the timeline by Swartz due to a meteor vast approching the present timeline, forcing Tsukasa and Tsukuyomi to withdraw for now. While Tsukasa brings her back, as he quietly notes that he now understands Tsukuyomi's story.

The Time-Space Conspiracy

"So...You want to become a King just because they are by your side?"
―Tsukasa reminding Sougo of who he really is and what he must do[src]

Woz, Sougo, Geiz and Tsukasa unite against Another Zi-O II.

After Zi-O has obtained the power of all the previous main Heisei Riders, Swartz tampers with the timeline by contracing with Hiryu Kakogawa to become Another Zi-O II, altering the present to create a reality where he ruled the world with an iron fist. In this altered reality, Tsukasa Kadoya still had his memories and saves Sougo from Another Zi-O II's forces with an assault rifle. Noticing how Sougo feels lonely without his friends, Tsukasa motivates him by reminding Sougo that he always desired to be king, not just because of his friends. This leads Sougo to find a way to fix the situation with Tsukasa.

Tsukasa and Sougo revisit the altered Geiz and Tsukuyomi and tried to persuade them that they are on the same side, much to skepticism. As Hiryu tries to abduct Tsukuyomi, using Another Kabuto and Another Build, to lure out Sougo Tokiwa, Tsukasa once again arrives in time, untransformed, to knock the Another Riders back with a pistol. He fights Another Zi-O II as Kamen Rider Decade, helping Tsukuyomi escape as he fought with Geiz. Despite everything, Tsukuyomi still ends up captured by Heure and brought to Swartz. Sougo, having failed to protect his friend, joins Decade and Geiz to fight Another Zi-O II form. However, the three Riders are overpowered by Another Zi-O II's abilities. Tsukasa summons an Aurora Curtain, allowing the three to retreat.

Swartz stealing Decade's Rider power.

Back to 9 5 DO, Tsukuyomi has her powers drained by Swartz and is returned thanks to Woz. Tsukasa begins to have a basic understanding of the situation at hand and everything that has happened since day one has been part of Swartz's plans all along. Sougo is determined to bring down Hiryu first, and Tsukasa is willing to help him do it. Tsukasa came with Sougo, Geiz, Woz to Hiryu's castle and bring about his end. Hiryu summons an army of Another Riders to fight the heroes. While fighting the Another Rider army, Diend appears and challenges Decade to a duel. Although Tsukasa has the upper hand, Daiki uses his new time powers to freeze Decade in place. Swartz makes his presence and uses a blank Anotherwatch to take away Decade's power. GrandZi-O eventually managed to defeat Another Zi-O II and returned the world to normal, but Tsukasa is no longer Kamen Rider Decade and he lies on the ground unconscious because of Swartz's assault earlier.

Sometime later, Tsukasa recovered from the loss of his powers. On a rainy day, Tsukuyomi finds Tsukasa on a bridge. The girl asks him about Swartz and his plans, and whether he has known their relationship from the start. Tsukasa just remarks that expected it and how Tsukuyomi is just like him. They are both otherworldly beings who do not originally belong to this reality. Although Tsukuyomi speculates the recent distortions in the timeline are the results of Swartz's scheming, Tsukasa theorizes that it is actually Tsukuyomi and Sougo's presence that has been the root of the problems, and Swartz is just simply taking advantage of their presence.

"It's true that you have taken my power. Unfortunately, my power is the existence of me itself."
―Tsukasa before he takes control of Swartz's Aurora Curtain [src]

After Swartz transformed into Another Decade and summons Kamen Rider Eternal to his disposal, Swartz mocks Tsukasa for being a weakling as he has already had his power stolen. Although he lost the power to become Kamen Rider Decade, Tsukasa still has his natural abilities, such as the ability to control Aurora Curtains. He uses it to teleport himself and Sougo to the Another Worlds, how Swartz can trapping victims into their own personal realities that can revive the Dark Riders. He then sends the young Rider back to help his partners fight Another Drive.

"I get the gist now. This world...has to be destroyed by my own hands!"
―Tsukasa upon seeing the chaotic combination of worlds[src]

Tsukasa decided to destroy World of Zi-O.

Suddenly, elements related with the previous Heisei Riders, like the Sky Wall and Futo Tower, started to appear out of nowhere. Sougo and Tsukuyomi learned of Swartz's true intention of stealing Sougo's power at its peak amd approach Tsukasa and ask him to bring them to the year 2058 again. This is where he discover Swartz's true plans, to gather all the twenty Rider powers from the different dimensions which will merge into one whole Earth. While the young Swartz tries to kill Tsukuyomi, Tsukasa takes the hit and dies. However, Daiki Kaito arrives and ressurected Tsukasa using the Zi-O II Anotherwatch that he swiped from Hiryu Kakogawa. Although he came back to life, the Anotherwatch consumed Daiki into becoming Another Zi-O II. Sougo returns the Decade Ridewatch to him, revealed to have contained half of his powers, and allows Tsukasa to become Kamen Rider Decade once more. After pushing Another Zi-O II back into the present, Decade transforms into Kamen Rider Zi-O and fights alongside GrandZi-O to defeat Another Zi-O II, freeing Daiki was free from the Anotherwatch's influence.

Decade and Diend vs. Another Decade

As more monsters started to surface and the city became in utter chaos, Tsukasa declares that Zi-O's world must be destroyed. After regrouping at 9 5 DO, Tsukasa explains that Swartz is trying to cause the destruction of everything by merging all the Kamen Riders' timelines into one and how Sougo is the catalyst to merge the worlds into one. Before he could destroy the world, Tsukasa works with the Kamen Riders in order to save the people in Zi-O's world first. A short while later, Tsukasa personally tells Sougo that if they choose to follow his plan, Sougo may not survive, only for the latter to respond that he has made up his mind ever since the day he's born. While Decade joins with the Kamen Riders to fight Another Decade, Diend comes to his aid as Another Decade arrived and both Riders are able to fight in equal footing against the Time Jacker with their abilities.

In order to save the residents of the World of Zi-O, Tsukasa's plan involved Tsukuyomi becoming a Kamen Rider and create a bridge between Sougo's world and Tsukuyomi's world as a new world to inhabit. However, in a surprise turn of events, Kamen Rider Tsukuyomi betrays everyone and sides with Swartz instead. Tsukasa, having no other options, asks them to be ready for the end of the world. As the Kamen Riders continue to fight Another Decade and his forces, Decade is frozen in battle by Tsukuyomi, only to be saved by Sougo at the last minute.

Tsukasa and Daiki during the world rewritten event.

"So, history is being rewritten?"
"I guess this will be the beginning of a new journey."
"
―Daiki and Tsukasa in the finale[src]

After Sougo destroys Swartz once and for all by becoming Ohma Zi-O, he decides to rewrite history rather than rule the world. Tsukasa and Daiki observe the timeline begin to be rewritten, the former taking a picture of the events with his camera.

Rider Time: Kamen Rider Decade VS Zi-O

Tsukasa Kadoya in Rider Time Decade

"It's been awhile, Yusuke."
―Tsukasa greeting Yusuke after they had not seen each other for a long time[src]

Alternate counterparts of Sougo Tokiwa, Swartz, Heure, Ora, and a couple of others became trapped in a mansion on a desolated island. A masked man orchestrates a "King Game", saying that whoever wins the game will become king of the world. Anyone who fails a task in the game will be killed by Another Ryuki. When Yusuke Onodera, Misa Kudo, and Swartz observe a deceased old man who has been killed by a mysterious person while holding a lot of cash, Tsukasa Kadoya appears and greets Yusuke after not seeing each other for a long time.

At first, the remaining people in the mansion are suspicious because of Tsukasa and Yusuke's acquaintedness. Tsukasa explains to his old friend that the mansion they are in is actually the entrance to a dimensional gap, and that the "King Game" has happened many times in the past. He also reveals he is chasing down the "True Sougo", who is the mastermind of the King Game and has been weakened due to using too much power as Ohma Zi-O. He further notes that nobody is to be trusted in the mansion, since it itself is connected to various worlds, and no one can know who is from what dimension. While he particpates in the masked man's games, Tsukasa proclaims he cannot lose, in order to draw the "true Sougo" out.

The masked man reveals his final challenge: The rest of the mansion must each find a treasure weapon in the compound and use them to kill one another until there is only one left, and Another Ryuki will be killing them at random also. Tsukasa learns that the Yusuke he has kept in communication with isn't the Yusuke Onodera he knew as he is revealed to be the mysterious killer all along. However, most of his victims had survived in particular, a Space Ninja Heure, a ghost Misa, and a robot Sougo Tokiwa. After drawing out the True Sougo and learning the masked man's identity as none other than Narutaki, Tsukasa transforms into Kamen Rider Decade and fights alongside Zi-O and also Diend, Kuuga, and Kiva-la against Ohma Zi-O in a wasteland. However, Ohma Zi-O is too powerful against the five. Zi-O, seeing no other choice, gives Decade the Saber Ridewatch, telling him to deliver it to someone who can use its power. Decade and the four other Riders are then defeated by Ohma Zi-O in a massive explosion.

Rider Time: Kamen Rider Zi-O VS Decade

Having survived the battle with Ohma Zi-O, Decade is still hellbent on ending his reign. Due to a distortion within several different timelines focused around their versions of Sougo Tokiwa, Tsukasa returns to destroy the resulting world by killing all of the alternate Sougos within, while trying to prevent Ohma Zi-O from rising into power. Driving a jeep towards Hikarigamori Academy, he spots a frightened, cowardly Sougo trying to run from him. Tsukasa stops the jeep and transform into Decade in order to kills that Sougo. Tsukasa eventually arrives at Hikarigamori, but turns around when the actions of Sougo C lead to a fight and lure out several more alternate Sougos.

The night afterward, it is revealed that Tsukasa is slowly starting to disappear, showing that his wound during the stab from the evil Yusuke and Ohma Zi-O actually endangered his life because Tsukasa has yet to be treated into full condition.

"My journey...is finally...coming to an end..."
―Tsukasa's final words before his death[src]
After the other alternate Sougos are erased through a mix of infighting and Tsukasa's own actions, the mysterious child Tsukuyomi has been helping appears and reveals himself as the "true Sougo" that Tsukasa has been hunting and has now become Ohma Zi-O. Tsukasa attempts to intervene by equipping the K-Touch and transforming into Decade Complete 21, but his weakened condition proves fatal, with Ohma Zi-O easily defeating Tsukasa once more. Once Sougo A manages to remanifest, he finds Tsukasa near the pond where Ohma Zi-O has defeated him earlier, and is given the Saber Ridewatch. Following Ohma Zi-O's destruction at the hands of DecadeArmor Saber Form, Tsukasa begins to disintegrate, relieved that his journey will finally be over before quietly passing away and restoring all seven timelines to their original state. Although he is apparently dead, Woz does believe Tsukasa and Ohma Zi-O may return in the near future.

Other Events

Cho Kamen Rider Den-O & Decade Neo Generations: The Onigashima Warship

Although Tsukasa and the Hikari Studio crew believed their mission in the World of Den-O was over, the true identity of the true culprits of the world's Den-O World's time distortions were revealed to be the Oni Brothers. Before they could even travel to the World of Kabuto, Sieg comes into the Hikari Studio with a manuscript showing a battle at Onigashima. With Sieg's help, Tsukasa and company travel with the DenLiner crew back in time to fight the Oni Brothers, Mimihiko and Kuchihiko, before returning to the present time in the World of Kabuto.

The Hikari Studio ends up in a world which is discovered to be Tsukasa's homeworld, the World of Decade, where Tsukasa meets his sister Sayo Kadoya and starts a Rider Battle tournament to find the strongest Rider to save the world after hearing he must be the one to do so by Nobuhiko Tsukikage, Sayo's butler.

Tsukasa wins and it is revealed that he was the Great Leader of Dai-Shocker. But the victory is short-lived as Nobuhiko is revealed to be Shadow Moon and Sayo as Priestess Bishum takes control of Yusuke to attack Tsukasa as part of revenge for abandoning her, despite not knowing the truth. Tsukasa is left alone as even his friends abandoned him. He is later encountered by Joji Yuki a former scientist for Dai-Shocker that wanted payback by Tsukasa for doing said punishment to him. Later he realizes that Tsukasa is no longer affiliated with Dai-Shocker and fights Dai-Shocker as Riderman as he lets Tsukasa escape .

Tsukasa joins in the fight against Dai-Shocker starting with the fight against General Jark, renewing Natsumi's trust towards him. He and all of the Kamen Riders fight Dai-Shocker vanishing Garagaranda and Ika Devil. Later Decade fights the Bishum-controlled Kuuga Rising Ultimate but realizing he's talking with his sister, he convinces Sayo that Nobuhiko is only using her to further his goals. Sayo knowing the error of her ways destroys the Stone of Earth, freeing Yusuke. With the stone destroyed, Shadow Moon fights Decade and Kuuga Rising Ultimate overpowering them until Kamen Rider Double shows up and flings him to Dai-Shocker's castle. Tsukasa along with all of the other Riders destroy Shadow Moon with an All Rider Kick. After Shadow Moon and the castle is destroyed, Kingdark appears. Diend summons Kamen Rider J and uses the Decade Final Form Ride to turn Decade into the Jumbo Decadriver and turns J into Decade Complete Jumbo Formation destroying Kingdark. Tsukasa later makes amends with Sayo and departs his homeworld with the Hikari Studio.

Kamen Rider G

"You are the only one who can save this world."
―Decade encourages G.[src]

At some point during his travels across the worlds, Decade came through an Aurora Curtain to a world which was home to Kamen Rider G, who was having a hard time against the Phylloxera Worm. Decade told G that he was the only one who could save his world. Decade was soon followed by the Nine Heisei Riders through the dimensional wall behind him. With a boost in confidence, G got up and destroyed the Phylloxera Worm with his Swirling Rider Kick as the ten Heisei Riders vanished.

Let's Go Kamen Riders

Decade's return in Let's Go All Riders.

A mishap caused by the Greeed Ankh unintentionally altered the timeline which enabled Shocker to utilize the Core Medal to create the Shocker Greeed which defeated the Double Riders and seemingly erased the legacy of the Kamen Riders from history. In 2011, after Kamen Rider New Den-O's attempt to repair the damage, he along with Kamen Rider OOO and M-Ankh awaited execution. However, it was revealed the Double Riders had their brainwashing removed by a Shocker scientist.

The Double Riders joined with New Den-O and OOO to fight Shocker's forces but were eventually defeated. When the order was given to kill everyone, V3 suddenly appeared, asserting that there were more than four Riders. V3 was soon followed by all the other revived Riders that came after him, as even though Rider's history was changed, the people's memories haven't changed. Decade appeared after the three 90s Riders and the first eight Heisei Riders, defeating the Paradoxa Undead, Tiger Orphnoch and Shadow Moon in quick succession.

After the Riders were united, they faced off against Shocker's Great Leader. Later, when joined by a force of extra Riders, Decade got into his Machine Decader, and alongside all the other Riders in their vehicles performed the "All Rider Break", ramming into the Rock Great Leader and defeating it once and for all.

Kamen Rider × Super Sentai: Super Hero Taisen

Decade vs. the Go-Busters.

"Destroy all Super Sentai... or die trying!"
―His words as the leader of Dai-Shocker[src]

Doctor G resurrected and gathered all defeated Rider villains, recreating Dai-Shocker. He told Tsukasa that the Riders and monsters needed to destroy the Super Sentai to ensure the survival of the Riders, and, answering that, Tsukasa took control of the new Dai-Shocker, becoming its Great Leader again to battle the Super Sentai and also the Dai-Zangyack, a new union of Super Sentai villains led by the GokaigerIcon-crosswiki.png's Captain MarvelousIcon-crosswiki.png. As the Great Leader of Dai-Shocker, Tsukasa apparently destroyed many Super Sentai teams such as the Goseigers. Gokai Red and Gokai GreenIcon-crosswiki.png was the last Sentai Ranger alive, while Decade himself was seemingly the last remaining Rider. After he was wounded in his battle against Gokai Red, Doctor G used the opportunity to overthrow him and take control of the organization. The story about Riders needing to destroy Sentai to survive was a lie, and Doctor G was actually allied with Dai-Zangyack and using both Gokai Red and Decade to destroy the other heroes and afterwards kill the nominal leaders of the two organizations.

Decade inserts the Reflecloud Gosei CardIcon-crosswiki.png into the Decadriver.

However, Tsukasa and Marvelous already realized that trap from the beginning before the war starts. The destruction of the Super Sentai actually just an act and the truth was, all the Super Sentai and Riders were just sent into a rift between dimensions. Tsukasa turned against Dai-Shocker and Dai-Zangyack, supported by all other Riders and Super Sentai. Alongside the Gokaigers, he killed General Shadow. In the end, he faced Doctor G, the man behind the new Dai-Shocker, and defeated him with the help of the Super Sentai team GoseigerIcon-crosswiki.png, and Kamen Riders Ryuki and Blade. However, after being defeated, Doctor G was revealed to be Decade's old enemy, Narutaki, who escaped afterwards, and his real identity was left a mystery. After the battle, Tsukasa reconciles with Daiki accepting his friendship before the latter takes his leave.

Super Hero Taihen

Kamen Rider Murder Mystery! You’re the Great Detective!

The Kamen Rider Club celebrates the film Super Hero Taisen as they enter the Rabbit Hatch. Shun Daimonji is shocked to discover the body of Kamen Rider Decade on their common table, with multiple cards stabbed onto his helmet. As the club ponders a hypothesis, Gentaro considers it might have been Hurricane RedIcon-crosswiki.png, to which the ranger arrives and denies any connection, suggesting it may NinjaRedIcon-crosswiki.png, who in turn implicates Gokai RedIcon-crosswiki.png. Another body is discovered- this time Kamen Rider Double. Kamen Rider Meteor arrives to "help" the investigation. However, this time, an Imagin is found, Momotaros with a peach cup in hand. After Fourze gathers up the clues, he thinks that it is neither one of the Red Rangers, but instead it is one of the staff members that are currently filming them. Fourze started to think that Decade, Double, and Momotaros have something in common: they are all have the same suit actor (Seiji Takaiwa), which leads him to the culprit who is Eitoku. Fourze then noticed that in the Kamen Rider Series, Eitoku portrays the majority of the suit acting of the secondary characters (Urataros in Den-O and secondary Riders from Decade to Fourze) and knows that he wants to kill Seiji for taking the lead role, but the Riders that he killed weren't suit acted by Seiji, instead by other suit actors as Fourze reveals to him that Seiji is currently suit acting Fourze. After Eitoku is arrested, the deceased Riders revealed to be alive as they all go out for lunch and Kamen Rider Faiz calls to make reservations.

Gokai Silver Gold Mode & Decade Complete Form.

Decade later appears in another segment where his Complete Form Mode appears alongside Gokai Silver's form, Gold Mode as one of the similarities between Decade and Gokaiger.

Super Hero Taisen Z

Decade and other space heroes.

Decade cuts down Pteranodon Yummy.

Space Sheriff Gavan Type GIcon-crosswiki.png, alongside Kamen Rider Beast and Yellow BusterIcon-crosswiki.png invaded the fortress of the Space Crime Syndicate Madou on Earth. However, inside, they're overrun by the forces of Space Shocker, which had allied itself with Madou. Gavan was separated from the others and trapped by Shocker's forces, when Kamen Rider Kamen Rider Fourze arrived, answering the call for help of Gokai SilverIcon-crosswiki.png, who asked for reinforcements to help in the attack. Fourze brought with him more allies, including Meteor, Super-1, the Super Sentai teams Choushinsei FlashmanIcon-crosswiki.png, Tokusou Sentai DekarangerIcon-crosswiki.png and Decade himself to confront Space Shocker. Decade briefly fights against Tortoise Undead and afterwards pierces through a Pteranodon Yummy.

Afterwards, Decade presumably stays fighting against the other reinforcements brought by Space Ika Devil, while Fourze is thrown out of the area. Space Ika Devil himself is finished by the Super Sentai team Gokaiger, while Gavan and Meteor leave to fight against Space Shocker's and Madou's leaders. After the battle is over, Decade appears on top of a nearby cliff alongside the other heroes who appeared to help to say goodbye to Gavan and the others.

Kamen Rider Wizard

"Someone once said...we don't fight for justice. We...fight for human freedom."
―Tsukasa telling Amadum what the Riders fight for.[src]

Tsukasa, Haruto, and the Heisei Riders.

Decade was summoned along with OOO by the alternate version of Haruto, taking the children to the shop. Before taking the children away, he thinks that he has arrived in the World of Wizard, but Haruto tells him that he is mistaken. The Kamen Rider Rings He is summoned again by Amadum to retrieve back the Fourze Rider Ring from Haruto. He then teamed up with Haruto along with the Heisei Riders to fight Amadum and his monsters. However, Amadum was too powerful for the Riders as he takes their items from them until Gaim arrives. Gaim easily beats Amadum up as the Riders regaining their items to transform into their final forms. After Amadum is defeated, and the Rider Rings gone, Tsukasa leaves to continue his journey, stating that Haruto and him will meet again.

Kamen Rider Taisen

"It's true that I travel the worlds, and met many friends... And some of them are already dead, But I won't forget them. I keep them eternally in my heart."
―Tsukasa & the Heisei Riders confronting 1 & the Showa Riders.[src]

Tsukasa in Kamen Rider Taisen

Tsukasa managed to find Kouta in Drupers, telling the young Rider that he somehow knew Shu before Narutaki appears to them. He warns the Riders about Badan's plan and the situation between the Riders from both eras, having Kouta become curious about it. Tsukasa would plan to gather the Heisei Riders as Kaito decides to join him. He takes Kaito to Futo, meeting up with Shotaro at the Narumi Detective Office as he offers the young Rider to help the detective on his case. Later, Tsukasa approaches Takumi, asking him to join the battle against Badan. Takumi refused until he was attacked by Badan's monsters. He arrived to fight them until Kamen Rider Fifteen appears to attack him before Decade retreats. Meeting up with Shotaro in Futo, Tsukasa asks the detective to join the battle against Badan and Shu's origins, which Shotaro would inform him about the boy.

Decade & the six remaining Heisei Riders

Tsukasa went to the lighthouse as he noticed that his mother, Saki looking at the picture with the note that Shu wrote as she blamed herself for his death. Decade arrived where Shu was and sent the boy to meet with his mother while Gaim distracts Fifteen. However, they were attacked by Badan's monster until Black and Black RX finished them off. Thanking both Riders, however, their next target would be the Heisei Riders as Shotaro arrived to distract both Riders. Once they reached the lighthouse, Shu was about to meet up with Saki, however Fifteen appears to retrieve his son as Tsukasa transformed to fight Fifteen. Overpowered by Fifteen, Gaim arrives to fight him, but failed to save the boy. Kouta was furious about Tsukasa not knowing Shu's feelings. Tsukasa would gather the remaining Heisei Riders as Kouta and Takumi would join him. Once the remaining Riders arrive, both sides attack as Decade and 2 were defeated by each other. However, all the Riders were freed thanks to Gaim as they started to battle the Badan Empire. Decade freed Shu from the machine as the ship was destroyed by Wizard, Faiz, and X. After battling the Badan Empire, Hongo stated that their battle wasn't over as the Rider War continues. However, the Showa Riders admit their defeat after seeing Gaim protecting a flower as they would congratulate the young Riders. Sometimes later, Tsukasa visits the lighthouse and looked at the photo of Shu that he took.

Super Hero Taisen GP: Kamen Rider 3

Due to the timeline alteration caused by Shocker, Tsukasa became one of the brainwashed Riders in that timeline, donning the name of Shocker Rider Decade. Alongside Agito Burning and Hibiki, Decade joined SkyRider, Super-1, ZX and the Shocker Combatmen against the double agent Kamen Rider 3, providing his Ride Booker's firepower in a combined projectile assault before proceeding to physically overwhelm Rider 3 as he allowed Mach to escape.

On the following day, Decade was one of several Shocker Riders who volunteered in the Rider Grand Prix under Shocker Rider 3, who had been personally challenged by Kamen Rider Drive. During the race, Decade, along with Agito, OOO and Fourze, found that his Rider Machine, Machine Decader, had been immobilized by Mach's Signal Tomarle. Decade ultimately fell short of the Top 2 in which Drive prevailed over Rider 3.

Once Rider 3 was integrated into the Great Leader of Shocker's Rider Robo form, Decade was among the Riders who appeared to attack Zeronos Zero Form and Denebick Buster only to be fought off by the turncoat BOARD Riders: Chalice, Leangle, Blade and Garren. Ultimately, the Double Riders 1 and 2 made their appearance having survived their apparent demise from within the Rider Robo, and broke Shocker's brainwashing on the fallen Riders, enabling all Riders to unite in a final battle against Shocker.

Surviving the onslaught of the History Modifying Machine, Decade fought and destroyed Shocker's Shvarian with the Dimension Kick shortly before the Rider Robo was destroyed along with the machine by Shurikenjin TridoronIcon-crosswiki.png. Among the remaining Riders who witnessed the farewell of Kyoichiro Kuroi as the perversion of history was reversed, Decade's place in history was restored.

Kamen Rider Build: Be The One

Among the first 18 Heisei Riders, Decade fought against numerous monsters in a melee briefly witnessed by Sento Kiryu before being caught in the crossfire as Kamen Rider Zi-O BuildArmor used his Vortex Time Break to wipe out his enemies.

Kamen Rider Heisei Generations Forever

Kamen Rider Decade in Heisei Generations Forever.png
In an alternate timeline created by the first Heisei Rider, Kuuga, being erased from history, but traces of the original history remaining due to a Singularity Point, Decade seemingly was known just as fiction alongside the other Heisei Riders. However, after Ataru Hisanaga and the other Riders themselves stand with their belief in the Riders strengthened, the Riders started returning and saving the people, who also started cheering for them as real heroes, bringing back more Riders.

Kamen Rider Zi-O: Over Quartzer

Once the Heisei Riders were restored after the birth of Zi-O OhmaForm, Decade appeared in battle alongside them, taking on several Kasshine Troopers, once again with his original Decadriver. Eventually, he makes it to the leader of the Quartzer alongside other Heisei Riders, turning into Complete Form for the final battle.

During the final battle against Kamen Rider Barlckxs, Decade attacks alongside other Heisei Riders, but it has no effect against Barlckxs' mix of J's and BioRider's powers alongside a barrier. Soon, however, when Zi-O OhmaForm arrives, all Riders attack in unison with their Rider Kicks, destroying him.

Video Game Appearances

Kamen Rider: Battride War

Kamen Rider Decade appears as a Main Rider in the video game Kamen Rider: Battride War, which unites the riders of the Heisei era from Kuuga to Wizard.

As in his series, Decade's primary skill is his ability to change into his nine predecessors using his Kamen Ride cards. In this state, he has access to some of their special attacks, though his strongest special remains the Dimension Kick (and using it will automatically revert him to Decade). His super form is Complete Form, and when activated he will perform a tandem finishing move depending on which Kamen Rider card is currently active. Decade Complete can perform a Final Attack Ride at any time by pressing R2 (the Final Form button) again, but doing so will cost energy and shorten the duration of Complete Form.

Decade's special attacks are:

  • Decade/Decade Complete: Attack Ride: Blast, Attack Ride: Slash, Dimension Kick
  • Kuuga: Uppercut, Mighty Kick, Pyrokinesis (Final Attack Ride)
  • Agito: Rider Punch, Ground Crash, Shining Clash (Final Attack Ride)
  • Ryuki: Strike Vent, Guard Vent, Burningsaber (Final Attack Ride)
  • Faiz: Sparkle Cut, Grand Impact, Photon Buster (Final Attack Ride)
  • Blade: Rushing Thrust, Serial Slash, Royal Straightflash (Final Attack Ride)
  • Hibiki: Rekkadan, Spinning Rush, Ongekiken: Kishin Kakusei (Final Attack Ride)
  • Kabuto: Clock Up, Avalance Slash, Maximum Hyper Cyclone (Final Attack Ride)
  • Den-O: My Finishing Move, My Super Finishing Move, DenKamen Slash (Final Attack Ride)
  • Kiva: Sliding Combo, Barrage Punch Combo, Emperor Moon Break (Final Attack Ride)

Kamen Rider: Battride War II

Decade in Strongest Complete Form in Battride War II.

Kamen Rider Decade reappeared in Kamen Rider: Battride War II, summoned by Cinema along with the remaining Heisei Riders in order to create the "ultimate movie". Decade's stage was based of from Kamen Rider Decade: All Riders vs. Dai-Shocker, with Kingdark as his main enemy. Decade's Strongest Form is Strongest Complete Form, whose moves are identical to the original version.

Battride War II also introduces Decade Violent Emotion from Kamen Rider × Kamen Rider W & Decade: Movie War 2010 as a separate and distinct character. While the original Decade has the power to transform into other Kamen Riders, Violent Emotion instead gains the ability to use their signature attacks (including some which aren't available to the originals, like Blade's Deer Thunder). His strongest attack is the Dimension Kick, resembling the "homing" version he used against Skyrider in Movie Wars 2010.

Decade Violent Emotion's special attacks are:

  • Decade: Attack Ride: Gigant, Attack Ride: Slash, Invisible (ends with Dimension Kick)
    • Kuuga: Mighty Kick
    • Agito: Rider Kick
    • Ryuki: Strike Vent
    • Faiz: Grand Impact
    • Blade: Deer Thunder
    • Hibiki: Ongekida: Kaen Rendan no Kata
    • Kabuto: Clock Up + Rider Kick
    • Den-O: My Finishing Move Part 2
    • Kiva: Barrage Punch Combo

Kamen Rider: Battride War Genesis

Kamen Rider Decade reappeared in Kamen Rider: Battride War Genesis

Kamen Rider Battle: Ganbarizing

Kamen Rider Decade is among the vast majority of Kamen Riders that are available in this arcade game. Later in Zi-O line, he also reprised with his new Neodecadriver. Notably, he is counted as Zi-O's character when equipping Neodecadriver, as the background music is Over Quartzer.

Novel Appearances

Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~

In the novel which is the reimagination of the TV Series, Tsukasa is generally the same personality wise. But his world is different from the world in Kamen Rider Decade: All Riders vs. Dai-Shocker movie. He has no sister and his parents live overseas. In the novel he’s described as a young NEET tired of his mundane life, the only thing he finds interesting is photography. He ends up stumbling upon an abandoned photo studio, inside he finds an old camera standing on a tripod. Tsukasa picks it up and peeks through the viewfinder. Through the viewfinder, Tsukasa sees a completely different world. Instead of a flimsy Eijiro Hikari that knocks down a backdrop, the group uses the camera to travel between worlds. In fact, Eijiro doesn’t even exist in the novel. The photo studio isn’t some ordinary photo studio that was just abandoned. It actually manifests itself in front of people that are tired of their own world and want to find a new world. Natsumi, Kaito and Narutaki, all found the photo studio in their own respective home worlds. In addition, Dai-Shocker, the evil organization itself never existed.

Tsukasa met Natsumi in the first unnamed world he traveled to. A world where monsters are attacking humans. Natsumi sees this and calls Tsukasa by the name ‘Decade’ and gives him the Decadriver, telling him he must transform. A confused Tsukasa goes along with it and becomes Decade for the first time. They travel to another world together and meet Daiki Kaito. He acts hostile towards Tsukasa but still decides to follow the two on their travels.

With 6 A.R. Worlds discovered leaving Den-O, Kuuga and Kabuto's World unexplored, the trio arrived at The World of Den-O with Tsukasa’s clothes change into a doctor’s uniform as they arrive. Tsukasa meets Ryotaro, but his Imagin friends are missing. Tsukasa agrees to help him find them. The Den-O characters feel very off-character as their characteristics are different. Momotaros comes off as rather polite compared to his jerkish and self-centered TV counterpart, and actually refers to people by their real names instead of snarky nicknames. The Final Form Ride remains the same, as Tsukasa turns Den-O into Momotaros.

Arriving at Kuuga's World, Tsukasa is dressed as a painter and meets Yusuke Godai while having difficulties of remembering the name Decade and usually goes with “Kamen Rider Dickens.”

Despite being Kuuga’s world, Tsukasa doesn’t interact much with Godai.

Instead he meets a mysterious unnamed girl, with her sentences spoken in broken grammar. This girl approaches different men saying “Do you want me?” The girl is referred as Yuri after Tsukasa sees her holding a lily flower, yuri in Japanese. She asks the question to Tsukasa, but Natsumi doesn’t like it and uses her Laughing Pressure Point technique on him. Yuri takes a liking to Tsukasa and connects with him. Tsukasa says they are the same type of people, and relate to each other. But he reveals that he never really paid attention to her and never cared about her. From the start, Natsumi oddly suspects that Yuri is a Gurongi. This is never truly touched upon until the where Yuri reveals the truth and challenge the Riders into a fight. Her Gurongi group is not mentioned, but she’s described as a Moth, meaning she's of the Ba class of Gurongi. She causes people to explode by sticking moth scales from her wings on people. Decade and Kuuga defeat her together. Decade's Final Form Ride for this Kuuga is also different: while it retains the ability to transform Kuuga into the Kuuga Gouram, the Gouram is described as a rhinoceros beetle, despite it traditionally being a stag beetle, which is also the same insect Kuuga is based on. Godai gives Tsukasa a thumbs up as they leave.

They shortly move onto the world of Kabuto, where they meet Soji Tendo, still as arrogant and confident as ever, and considers himself as the strongest Rider ever. The group enters Bistro La Salle where Hiyori Kusakabe works. Hiyori sees Kaito and Tsukasa, dressed as ZECTroopers, claiming that the two of them ate without paying. Tendo hears this and is enraged. The three of them fight and Tendo actually beats them with only a pair of chopsticks. However, it turns out to be a pair of Worms that ate without paying. Tsukasa and Kaito are eventually captured by ZECT, only to have Tendo save them. Tsukasa thanks him and says that he never thanks people. Tsukasa starts respecting Tendo. For some inexplicable reason, Tendo has the Clock Up Attack Ride Rider Card and gives it to Tsukasa after he realizes that he is Kamen Rider Decade. Tsukasa uses the Clock Up card as Kuuga, meaning the Attack Ride cards aren’t restricted to their respective Riders in the novel. In the end, the Worms that impersonate both Tsukasa and Kaito have been defeated. As the fight is over the trio goes back to Tsukasa's world.

Between all the traveling, a vampire has been attacking in Tsukasa’s world, leaving behind drained corpses. The group investigates and they find out that Narutaki is the vampire. Just like the group, Narutaki originally had his own homeworld, but abandoned it to find a new one. However, he’s been traveling for so long that his mind has been deteriorating and can barely remember who he really is. He was originally a human, but somehow in his journeys, he had lost his humanity. The Kamen Riders have very pure energy that Narutaki seeks to consume: the Rider Cards. Thus, he sends Kaito to steal them for him. Kaito reveals his betrayal towards the team and gives Narutaki Tsukasa's 9 Heisei Rider Cards and Narutaki reveals his real form: a red-hued demon.

Kaito suddenly has a change of heart and sacrifices himself to save Tsukasa. All hope seems to be lost; Tsukasa even uses a Diend card with the DecaDriver, which turns him into a cyan-hued version of Decade. However, all seems hopeless, as he was badly overpowered by Narutaki and reverts into human form again. Natsumi, who had just realized that she has special powers all along, creates a special card with the 9 previous Heisei Riders on it. Tsukasa uses it, which summons the previous 9 Heisei Riders to do their finishers onto Narutaki. They then turn into cards and attached themselves onto Decade, turning him into Final Kamen Ride: Tsukasa, which can be described as Complete Form without a K-Touch. Tsukasa then finishes off Narutaki via a Rider Kick. In his dying words, Narutaki wanted to destroy all worlds and then create his own ideal world. He dies looking at Natsumi, knowing that she had the power to do what he wished for.

With the crisis over, Tsukasa returns to his world and Natsumi decides to go with him and live in his world. When they return, Tsukasa finds an article where it says Tsukasa's world's version of Natsumi died after committing suicide due to worldly troubles.

A few decades later, an unchanged young Kaito revives and reappears in front of an elderly Tsukasa. Kaito tells him it’s time to visit Natsumi’s world. There they are greeted by a young Natsumi, and Tsukasa finds himself as a young man again.Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~

Novel: Kamen Rider Gaim

In the darkness, Mitsuzane feels the existence of mankind. An unknown person approaches him and calls him a 'hero'. He asks whether there are people stranded in a similar situation. Sensing Mitsuzane's weak personality, the man encourages him to gather courage and move forward, never to give up. He shows Mitsuzane what is truly expected of a warrior, and the importance of Kamen Riders in the world.

"Everybody can be a hero!". Mitsuzane finally remembers who he truly was. In his hand's grasp, is a Lockseed he fondly remembers. Breaking through the darkness, he runs into the light.

Personality

According to others, he was the ruthless and unforgiving leader of Dai-Shocker who easily tortured and killed people with little to no remorse.

As Tsukasa traveled between dimensions, his clothing changes to suit the Rider's World, including some accouterments similar in color to his camera and Decade. He also exhibits some prior knowledge or talent necessary to his quest in the Rider's Worlds he enters. Some examples are his knowledge of the Gurongi language in Kuuga's World and his enrollment as a student in Faiz's World. He has also mentioned before that he is capable of doing anything except for taking photos. He also tends to tell American jokes from time to time that sometimes scares others. He is also quite cocky as he often taunts people from time to time.

However, due to his travels, he slowly lost his memories and ended up in a world in with no clear goal in life. He became very hypocritical and self-righteous and possessed a strong desire to "catch the world" using his photos. Unbeknownst to him due to his status as an outsider of the world, his photos do not develop well and foreshadow his fate as the Destroyer of Worlds. It's because of this that Narutaki began to follow him into worlds to spread a fact that Decade will one day destroy them all.

Despite having several unsympathetic traits, Tsukasa still tries to save innocent people as Decade, while teaching both the A.R. Riders and himself a valuable lesson in life.

After fully reclaiming his memories, his personality gained qualities from both his old and new selves. Instead of outrightly claiming that a world needs to be destroyed, he now closely observes the events of the worlds to determine whether it is required to destroy it or not, even looking into its past and future, like what he began to do in the World of Zi-O due to the possible emergence of Zi-O becoming Ohma Zi-O. If required, he may also temporarily ally himself to the villains of that world without them knowing his true motives. However, he still maintains his heroic nature whenever he needs to fight the evil himself. He is also willing to sacrifice himself if it is for the greater good.

Tsukasa's Magenta-colored Camera.

Before a climactic battle begins, Tsukasa answers a major villain's demand for his identity by saying that he is "Just a passing-through Kamen Rider, remember that!" (通り過がりの仮面ライダーだ、覚えておけ!, Tōrisugari no Kamen Raidā da, oboeteoke!).

On a humorous note, he heavily disagrees if someone defines his Rider form is pink, causing him to explain at length that Decade is magenta to others' annoyance.

Tsukasa uses a "Decade Pink" Blackbird Fly 135 Twin-lens Reflex Camera.

Powers and Abilities

The many roles of Tsukasa.

Powers

  • Resurrection: If people still remember him, he can be resurrected from the dead. Kamen Rider × Kamen Rider W & Decade: Movie War 2010
  • Dimensional Travel: An otherworldly human himself, Tsukasa can travel within worlds via Dimensional walls. However, the downside is that he is unable to take pictures perfectly in the world he resided unless if he is in his true world. Also to be noted is that the people taken by said pictures often suffer in one way or another. After Swartz had stolen his power, Tsukasa is still capable to control this power freely, as he claims this power stems from his very existence itself, surprising Swartz. He can send people into a dimensional rift, a space between worlds, with just one swing of his sword.
    • Time Travel: Tsukasa is seemingly able to travel to different periods of time via the Aurora Curtains, as performed when he follows Geiz to 2015, and previously when delivering Sieg to Onigashima in the Muromachi period.
  • Temporal Protection: Due to being an otherworldly human himself, he is unaffected by the changes Sougo's adventures have caused, including having the knowledge and powers of Riders who Sougo's actions had erased from time and history like Build and Wizard. He is also completely immune to the alteration of the timeline caused by Hiryu Kakogawa. Likewise, this power allows Tsukasa to act as a time capsule for histories and worlds of both main timeline and A.R. World Riders and allows for their restoration should they be erased from existence or their history altered, contingent on Tsukasa bearing the Rider card for them by which said original history is stored.
  • Nine Worlds Powers: Due to having no real home of his own, whenever Tsukasa travels to another world, he takes on a role within it, granting him different abilities as well as all necessary needs to take on that role (IE clothes, hairstyles, documents, etc.). These abilities are retained after acquisition of their respective world's Rider cards.
  • Ridewatch Manipulation:
    • Ridewatch Nullification: Due to bearing an unaltered version of a Rider's history by way of his Rider cards, Tsukasa is capable of nullifying the power of any Ridewatch or Ridewatch-based abilities, nullifying the Ghost Ridewatch in front of Geiz. Theoretically, this allows him to neutralize any and all powers of Ohma Zi-O on his own.
    • Decade Ridewatch Creation: Tsukasa can create a Ridewatch which houses half of his own Kamen Rider power. Not only enabling Zi-O to use Decade's power while staying Kamen Rider himself, but this also allows him to regain Decade's power even after Swartz stole it. Both are feats that can't be done by other Legend Rider due to the memory loss and history alteration that is normally a consequence of a Ridewatch's creation.

Former Powers

  • Reality Alteration (Uncontrollable): As a result of the actions of Dai-Shocker (and compounded by their own dimension-fusion plans beginning the process independent of Tsukasa's actions), Tsukasa's presence can cause A.R. Worlds to intersect with one another, risking the erasure of those worlds and its people as a result. After the defeat of Dai-Shocker and his initial death at the hands of Natsumi undoing their influence upon him and restoring the damage to the multiverse, this has stopped and does not continue after his resurrection.

Abilities

  • Peak Human Condition: As the former leader of Dai-Shocker, it is presumable that Tsukasa was skilled at fighting even before the start of his series. In fact, it seems that Tsukasa's abilities far surpass a normal human since he defeated two high-level Orphnochs in tennis and used a card as a shuriken to cut a chain. In theory, it is possible that Tsukasa may not be a normal human as he was the Great Leader of Dai-Shocker with most of the High Ranking Members being powerful creatures and cyborgs themselves. He is also able to survive two slashes by Nobuhiko Tsukikage using the Satansaber.
  • Expert Combatant: Tsukasa does not learn any martial arts, but he has great reflex and fighting skill to face his opponent mostly with less hardship. As Kamen Rider Decade, with the capability to turn into any primary rider, he uses their power and makes his own fighting style. Without copying the power of the primary rider, Tsukasa as Decade is still a dangerous foe with its own power as a balance fighter. Despite being a balanced fighter, Tsukasa mostly fights in close combat. The way he faced his opponent during amnesiac and the normal condition only differ in the strategy he used. After recovering from his memory, he mostly not fighting seriously to analyze his opponent's skill while during his amnesiac period he will figure a plan to outwit his opponent immediately. In Kamen Rider Zi-O, he is able to fight on equal grounds with the heroes and villains of the series despite having only half of his full power intact, emphasizing his skill and strength as a Kamen Rider. The only weakness of Tsukasa on facing his opponent completely is from a sneak attack which he can't expect.
  • Gifted Intellect: He is very calculative, cunning and manipulative, he became Leader of Dai-Shocker when he was young, outsmarted many villains, easily manipulates Dai-Shocker and Zangyack alongside Captain Marvelous. Very quick at infiltrating parallel worlds with limited information on those realities, which led him to solve many problems. However, he was unable to notice his sister betrayal due to lack of sympathy with his original personality. Moreover, even after losing his previous memories, He could easily fight against most of the A.R Riders while holding back. By transforming into Decade, he could seemingly use all of the other main Rider's powers (even when he had no idea of how his Rider System and the previous Rider Powers work while not able to use them as effectively or skillfully as the originals, but can turn it into his own style) and fight against his former subordinates as well as other monsters.
    • Great Kamen Rider Knowledge: Tsukasa is shown to have a lot of knowledge related to any Kamen Rider, be it Kamen Riders of another world like Ryuga, those from the future like Ohma Zi-O, as well as Kamen Rider Ginga.

Kamen Rider Decade

Kamen Rider Decade (NeoDecadriver Version)

"Kamen Ride: Decade!"
―Transformation announcement[src]

Rider Statistics (Original → NeoDecadriver)

  • Height: 192 cm[1][2]
  • Weight: 83 kg[1][2]
  • Punching Power: 4 t.[1] → 15.8 t[2]
  • Kicking Power: 8 t.[1] → 36.4 t[2]
    • Dimension Kick: 30 t.[1]
  • Maximum Jump Height: 25 m.[1] → 40.2 m[2]
  • Maximum Running Speed: 100 m. per 6 sec.[1] → 3.7 sec.[2]

This transformation is the default form of Kamen Rider Decade using the "Decade" KamenRide Card with the Decadriver.

After acquiring the NeoDecadriver, the capabilities of this form improve exponentially in all categories, even surpassing his previous Final Form (i.e.: Complete Form). Such improvements are evident in many instances, including being able to engage both Kamen Riders Zi-O and Geiz with relative ease (even when Zi-O is equipped with the DecadeArmor); to compete with enhanced Another Riders such as Another Zi-O II either with assistance (i.e. GeizRevive) or without; to overpower a similarly enhanced Kamen Rider Diend. Even when having only half of its full power at his disposal, Tsukasa proves to be fully capable of competing against Zi-O Riders and Another Riders alike.

While the original specifics of Kamen Rider Decade's armor were previously unknown, after upgrading to the NeoDecadriver, the following components were identified:[3]

  • Kamen Rider Decade (NeoDecadriver Ver.) Head (仮面ライダーディケイド(ネオディケイドライバーVer.)頭部, Kamen Raidā Dikeido (Neo Dikeidoraibā Ver.) Tōbu) - The helmet.
    • Dimension Vision (ディメンションヴィジョン, Dimenshon Vuijon) - The eyes. It has 1.5 million photoreceptors installed (eight times more than a normal human's eyes would have), allowing Decade to identify moving objects in a 25 degrees radius up to 40km ahead. It also has night vision functionality, infrared capabilities and can even perceive the dimensional walls between parallel worlds.
    • Boom Voice (ブームボイス, Būmu Boisu) - The mouthpiece. It can project Decade's voice extremely loudly and can project it so loud that it can shatter rock as thick as 10m through soundwaves alone.
    • Ride Plates (ライドプレート, Raido Purēto) - The various plate segments on Decade's helmet. It allows Decade to pass through dimensional walls.
    • Signal Pointer (シグナルポインター, Shigunaru Pointā) - The yellow signal device on the forehead. It emits a signal that allows Decade to turn other Kamen Riders into 'impractical objects'.
    • Dimension Scouts (ディメンションスカウト, Dimenshon Sukauto) - The earpieces. Allows Decade to detect 10Hz-14Hz sounds, low frequencies which should be ordinarily inaudible to the human ear.
  • Divine Suit (ディヴァインスーツ, Divuain Sūtsu) - The bodysuit. It is elastic, allowing Decade to move in combat unhindered. It can withstand temperatures as low as absolute zero (-273.15°C) and as high as 6000°C. It can also protect the body against electrons, protons, electromagnetic rays, infrared attacks and X-rays.
  • Divine Muscle (ディヴァインマッスル, Divuain Massuru) - The chestplate sections and black abdomen section. It acts as one giant shock absorber that protects the lungs, heart, abdomen and other vital organs by reducing the impact of shocks to non-lethal levels.
  • Divine Armor (ディヴァインアーマー, Divu~ain Āmā) - The shoulders. It is a robust frame that can withstand 50 tons of impact force and is light as pumice. It is made of the mysterious Divine Ore (ディヴァインオレ, Divuain Ore).
  • Tesla Bands (テスラバンド, Tesura Bando) - The wrist sections. It can emit microwaves, and by utilizing resonance it can make Decade float.
  • Beat Knuckles (ビートナックル, Bīto Nakkuru) - The hands. The fingertips are covered in Divine Ore, increasing the power of punches and chops.
  • Body Groove (ボディグルーブ, Bodi Gurūbu) - The grooves and lines that run across Decade's chest, shoulders and limbs. It is a reinforced frame that uses the Divine Suit as a skeletal muscle. Due to being made from Divine Ore, it is effective against blow attacks.
  • Foot Stompers (フットストンパー, Futto Sutonpā) - The feet. The toes are covered with Divine Ore, increasing kick efficiency.

Like other KamenRide & FormRide forms, this form has access to an specialized set of AttackRide Cards. This includes the Blast, Slash, Illusion and Invisible cards. Decade also possesses a dedicated Final AttackRide Card which activates a specific Kamen Rider Finisher depending on the configuration of the Ride Booker:

  • Dimension Kick (ディメンションキック, Dimenshon Kikku): Available with the Ride Booker in Book Mode, this activates Decade's Rider Kick, which strikes with a flying side kick.
  • Dimension Slash (ディメンションスラッシュ, Dimenshon Surasshu): Available with the Ride Booker in Sword Mode, this activates Decade's Rider Slash, which strikes with a highly-energized pixelated blade.
  • Dimension Blast (ディメンションブラスト, Dimenshon Burasuto): Available with the Ride Booker in Gun Mode, this activates Decade's Rider Shooting, which fires a highly-energized, pixelated projectile.

When a Decade Final AttackRide is activated, the Decadriver reproduces Decade's Final AttackRide card as human-scaled holographic constructs which acts as portals through which Decade's attacks travel along. These portals track their targets at high-speed and with incredible accuracy, adjusting to their evasive movements by reshuffling and stacking upon each other like a wave. During Kamen Rider × Kamen Rider W & Decade: Movie War 2010, Decade's Dimension Blast was able to track Skyrider during high-speed flight and strike him despite his evasive maneuvers. These holographic cards can also stun certain targets caught between them.

Kamen Rider Decade's ending theme is "Ride the Wind".

Complete Form 21 (コンプリートフォーム21, Konpurīto Fōmu Toenti Wan) is a further evolution of Complete Form. It is adorned with the Final KamenRide Cards of Zero-Two and Decade on the head, the Final KamenRide Cards of the other 19 main Heisei Riders across the chest and shoulders, and a cape with the Final Attack & KamenRide Cards for all 20 main Heisei Riders, the KamenRide Cards for the Secondary Riders and Final FormRide Cards for the Phase 1 Riders. As Kuuga has no secondary Rider, the Kuuga Rising Ultimate Final KamenRide card is used instead. All Phase 1 cards are on the right side of Decade's body right, Phase 2 is on the left, and Decade and Zi-O are centered (flanked by the Final FormRide Cards) similar to Grand Zi-O.

In this form, Decade can also wield the NeoDiendriver.

When Kamen Rider Diend uses a Final Form Ride card that turns Decade into the Jumbo Decadriver (ジャンボディケイドライバー, Janbo Dikeidoraibā), a larger version of the Decadriver which is worn by a Diend Kamen Ride Card-summoned Kamen Rider J to transform into Complete Form Jumbo Formation (コンプリートフォーム ジャンボフォーメーション, Konpurīto Fōmu Janbo Fōmēshon). This Complete Form is identical in appearance to the regular version, except he is J's Jumbo size and he wears the Decadriver, but lacking a K-Touch.

Rider Statistics

  • Height: 192 cm
  • Weight: 83 kg

Ability Parameters

  • Punching Power: 5 t.
  • Kicking Power: 10 t.
  • Maximum Jump Height: 30 m.
  • Maximum Running Speed: 100 m per 5 sec.

Kamen Rider Decade Violent Emotion (仮面ライダーディケイド激情態, Kamen Raidā Dikeido Gekijōtai) is Decade's false final transformation into the destroyer of worlds, with distortions around his eyes and the sides of his helmet, and the normally yellow Signal Pointer (the light on Decade's helmet) is violet. While this form appears similar to Decade's normal form, it is much stronger and able to use Attack Ride cards such as Clock Up without having to transform into the associated Rider first. This form is apparently no longer accessible as Tsukasa's "role" as a destroyer was fulfilled and then negated with the survival of the Multiverse and restoration of the primary Kamen Rider Universe.

This form is exclusive to Kamen Rider × Kamen Rider W & Decade: Movie War 2010.

Cyan Decade

Kamen Rider Decade Cyan Version

Cyan Decade in the net movie.

In Kamen Rider Decade: The World of Tsukasa Kadoya ~The Garden Inside the Lens~, Tsukasa uses Diend's Kamen Ride card to transform into a cyan-colored Decade.

A cyan Decade was previously shown in Petition! Diend Super Machine Legend!!, the third installment of the Kamen Rider Decade: All Riders Super Spin-off net movie series, when he entered Toei's Rider Machine Planning Room (Color Adjustment Room). There he saw his Machine Decader bike also colored cyan, referred to as the "Machine Diender", which was promptly taken by a green-colored Diend.

Sword Form

Kamen Rider Den-O

"Sword Form!"
―Sword Form's transformation announcement[src]

Rider Statistics

  • Height: 190 cm[7]
  • Weight: 87 kg[7]

Ability Parameters:

  • Punching Power: 5 t.[7]
  • Kicking Power: 7 t.[7]
  • Maximum Jump Height: 35 m.[7]
  • Maximum Running Speed: 100 m. per 5.2 sec.[7]

Tsukasa was also once possessed by Momotaros, who then used the Den-O belt to transform into Sword Form to fight the Mole Imagin.

When possessing Tsukasa (or anyone else) or by himself, Momotaros can assume Den-O's Sword Form through the Terminal Buckle, the first and most used form in the series. When in Sword Form he uses the DenGasher as a standard sword-style weapon. This form is the most balanced among Den-O's forms, probably due to Momotaros' prominence among the other Imagin. He occasionally forms different finishers for defeating enemies, despite parts 2, 3, and 5 being similar to each other. He also uses a Special Version in I'm Born which resembles the aforementioned parts, the only difference is that Full Charge is used twice. There is also a Final Version used against the Death Imagin which uses energy from the other Taros, Sieg, and Kamen Rider Zeronos. In the Cho Den-O series Sword Form also has a triple Roundhouse Rider Kick that Momotaros dubs his "Super Finishing Attack." The DenKamen Mask resembles two halves of a peach, which is based on the story of Momotaro.

Behind the Scenes

Portrayal

Tsukasa Kadoya is portrayed by Masahiro Inoue (井上 正大, Inoue Masahiro), who reprised his role in Kamen Rider × Super Sentai: Super Hero Taisen, the special episodes of Kamen Rider Wizard, Heisei Rider vs. Showa Rider: Kamen Rider Taisen feat. Super Sentai, and Kamen Rider Zi-O.

While disguised as Kamen Rider 1 in Kamen Rider × Super Sentai: Super Hero Taisen, he is voiced by Tetsu Inada (稲田 徹, Inada Tetsu). In Kamen Rider × Super Sentai × Space Sheriff: Super Hero Taisen Z, Kamen Rider Decade's voice was provided by Katsuhiro Suzuki (鈴木 勝大, Suzuki Katsuhiro), who plays Hiromu Sakurada/Red BusterIcon-crosswiki.png in Tokumei Sentai Go-BustersIcon-crosswiki.png.

As Kamen Rider Decade, his suit actor was Seiji Takaiwa (高岩 成二, Takaiwa Seiji), who has been the suit actor for the majority of leading Kamen Riders in the Heisei era (except Kuuga and Hibiki). In Super Hero Taisen and Kamen Rider Taisen, his suit actor was Jun Watanabe (渡辺 淳, Watanabe Jun). In Kamen Rider Zi-O, his suit actors were Yuji Nakata (中田 裕士, Nakata Yūji) and Kosuke Asai (浅井宏輔, Asai Kosuke).

Rider No.

As the leading Rider protagonist of Kamen Rider Decade, Tsukasa Kadoya (Kamen Rider Decade) is labeled Kamen Rider #25 (仮面ライダー25号, Kamen Raidā Nijūgogō) and Heisei Rider #10 (平成ライダー10号, Heisei Raidā Jūgō). Quiz! Decade Countdown!!

Etymology

Tsukasa's name is a homonym of the phrase "user and card" (カードや使さ, Kadoyatsukasa).

Meme

  • Decade's suit color has often a subject of a joke where Tsukasa claims it's not pink, but rather magenta, and he is very adamant of that. In the production stages of Decade, one of the reasons that Bandai and PLEX went with the color is because producer Hideaki Tsukada often wore pink clothing. However this gag has been often pointed out across many different medias.
    • Tsukasa owns a Blackbird Fly 135 Twin-lens Reflex Camera colored "Decade Pink".
    • In Check! Pink's Revenge, Decade SOS!!, Tsukasa is offended of Decade's suit color being called pink, vehemently defending that his Rider form is magenta.
    • In episode 14.5 of Kamen Rider Zi-O: Supplementary Plan, titled Pink Devil, Tsukasa was irritated because they keep referring him as 'Pink Guy' and defends his color designation as magenta.
    • In Episode 42 of Kamen Rider Zi-O, when Geiz calls Decade "the Pink guy", but Sougo corrects him by telling that his color is magenta, making this the first time Decade's color is mentioned in a canon episode.
    • This joke crosses in real life when Masahiro replies to tweets about the color with a plain "It's Magenta" (マゼンタだ, Mazenta da) or "Magenta".
  • The new final form of Decade, Complete Form 21 has been roasted by fans even by Masahiro himself as he makes a joke that the future Decade would have his horn tall like a tower.
    • Ever since Tsukasa/Decade Complete Form 21 is defeated by True Sougo/Ohma Zi-O in Final Chapter: The Last Sougo, some fans like to jokingly infer that Decade Complete Form 21 can be defeated if his opponent is a Golden-colored Kamen Rider (such as Kenzaki/Blade King Form).
    • Complete Form 21 and K-Touch 21 are also been roasted by fans due to the power itself are considered as "20 Heisei Riders + 1 Reiwa Rider" which some fans like to jokingly infer that Zero-One's power was not supposed to be added for the updated K-Touch.

In Popular Culture

Haiyore! Nyarko-san episode 3 contains an extended reference to Decade in the rooftop lunch scene. Cuuko teases Nyarko with a cake from the legendary space bakery DK-Do, owned by a man named D. Endo. The cake is said to be a limited 10th anniversary special production, and is modeled on the Decadriver; additionally, when Nyarko explains about the bakery to Mahiro, its name appears in black and magenta stripes, while D. Endo's is represented with black and cyan. Later on, Nyarko transforms her pet Shantak-Bird into a motorcycle, with her remarking "This may tickle a bit. Heck, it'll only hurt for a moment;" in the light novels, this Final Form Ride-style forced transformation is explicitly stated to be one of Nyarko's unique special powers.

  • Additionally, Nyarko's favorite television show is Iron Striver, a tokusatsu show made on Earth that serves as an obvious homage to the Kamen Rider franchise. A brief segment of the show seen in the OVA episode "How to Defeat a Kind Enemy" shows it to mostly be based off of Decade, with the main character physically resembling Tsukasa and using with a card-reading belt that forms the word "StriveRide" to transform. Said segment also features direct quotes from Decade, with Striver telling the villains "Bring it on! I'll destroy everything!"

Notes

  • Tsukasa crossing-over with Samurai Sentai ShinkengerIcon-crosswiki.png marked the beginning of future crossovers between the Kamen Rider and the Super SentaiIcon-crosswiki.png, such as Kamen Rider × Super Sentai: Super Hero TaisenIcon-crosswiki.png.
  • While using Kamen Ride Ryuki, Tsukasa displays the unique ability to enter and exit Mirror World from any reflective surface regardless of the original entry point, all without a Rideshooter, something that the Riders in Ryuki cannot do.
  • Tsukasa (and eventually Inoue himself) insists that Decade's pink color is actually magenta, which has become a meta-joke.[12]
  • Tsukasa using the Goseigers' Reflecloud card may also be a reference to his insert theme Ride the Wind.
  • Tsukasa and Kaito were the only Legend Riders to have had recurring roles in Kamen Rider Zi-O; all other previous Riders have only been featured as guests.
