Aruto Hiden (飛電或人 Hiden Aruto) is a 22-year-old aspiring comedian who became the CEO of Hiden Intelligence after the death of his grandfather. Originally uninterested in taking up the position, he became witness to the terrorist attacks committed by MetsubouJinrai.net and reluctantly became Kamen Rider Zero-One (仮面ライダーゼロワン Kamen Raidā Zerowan) for the sake of pursuing his dreams of making others smile.

History

Early Life

Aruto Hiden was born the grandson of Hiden Intelligence CEO, Korenosuke Hiden. His father, Soreo Hiden, passed away when he was young, so Aruto was raised by a HumaGear resembling his father to take Soreo's place as a parent and an emotional support.

Aruto and Soreo were present on the day of the Daybreak Town Accident, where they were enjoying a family outing with young Aruto spent most of his time engaging in comedic antics. When the 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.

Becoming Zero-One

At the age of 22, Aruto is continuously struggling to hold his career as a 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,

Brought before the executive committee, Aruto reads his late grandfather's wills and is shocked to discover 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.

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 it but is beaten senseless. After getting triggered 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 and destroys the Magia henchman as well as the Berotha Magia. After his first battle, Izu reveals that by accepting the Zero-One Driver, Aruto had also accepted being the president. Originally being reluctant to do so, he was re-inspired after seeing the park manager be grateful for Zero-One.

Kamen Rider Zi-O: Over Quartzer

(The following event is a dream sequence and may or may not be canon)
Zero-One appeared to face the heavily injured Kamen Rider Zonjis, introducing himself to be the only one for being the true first Reiwa rider, Zero-One. Aruto defeated Zonjis easily by using his Rising Hopper and Flying Falcon forms, followed by Black Woz celebrating his arrival.

Personality

Aruto is a cheerful individual who loves to make people laugh, and doesn't give up even if he fails to do so. Despite this cheerful trait, he will not hesitate to fight back against people who threaten that happiness. To this end, he reluctantly becomes a Kamen Rider not to be a company president, but to be someone who can protect the peace.

Due to his upbringing, he has a very positive outlook on HumaGears, and strongly believes they can prosper alongside humanity. This makes destroying Magias difficult for him, especially if they were former Humagears he knew personally. He eventually gets accepts and past this weakness by the time he encounters Kobe Sakamoto.

Aruto also has a strong sense of empathy, shown towards Seiji Tazawa whom both had lost someone close to them and required a HumaGear to take their appearance for emotional support. To this end, Aruto was willing to put himself as a person first rather than immediately have Seiji arrested for breaking the law.

During mid-battles, he will say "There's only one person who can stop you, and that's me!" (トラちゃん Omae o tome rareru no wa tada hitori, ore da!).

Aruto also playfully refers to his Progrise Keys [i.e. he calls the Flaming Tiger Key and its corresponding animal "Tora-chan" (トラちゃん)]. This is very evident with Flying Falcon, where every time he meets Jin he will demand Jin to return "Tori-chan" (トリちゃん).

  • Bear Neck (ベアネック Bea Nekku) - The thick collar piece. It covers the Hiden Linker, greatly increasing its defense. At the same time, a built-in superconducting unit works in tandem with the Rise Architecter to give tremendous strength to the upper body.
  • Bear Shoulders (ベアショルダー Bea Shorudā) - The shoulder armor. It is covered with Transpar. It can destroy objects by freezing them first before hitting them. This protects the shoulder and expands the wearer's combat prowess by replicating a polar bear's abilities.
  • Bear Gauntlets (ベアガントレット Bea Gantoretto) - The forearm armor. It has a built-in Polar Freezer (ポーラーフリーザー Pōrā Furīzā) freezing unit that allows Zero-One to release a special freezing agent from his palms to freeze an opponent. Furthermore, by utilising the Bear Claws (ベアークロー Beā Kurō) at the fingertips, they can shatter frozen objects and tears through everything.
  • Bear Legs (ベアレッグ Bea Reggu) - The legs. It boasts a maximum kick force of 31.9 tons due to it drawing out the user's physical abilities. The thigh armor adjusts the Rise Architecter so that it does not harden or break during extremely low temperatures, allowing it to exhibit the same performance as if it were in normal temperatures. In some certian cases, the fluidity of energy may be maintained via supercooling.
  • Bear Greaves (ベアグリーブ Bea Gurību) - The shin armor. It has a built-in icing device that can cool down the body's temperature that has been raised during battle, prevent injuries, reduce muscle pain/fatigue accumulation, and take care of the wearer.
  • Bear Boots (ベアブーツ Bea Būtsu) - Zero One Freezing Bear Boots. It is protected by armor composed of Hiden Alloy (which has a Knoop hardness of 8200), and can function as a spike by deploying its built-in Bear Claws (ベアークロー Beā Kurō), allowing Zero-One to maintains the same running power even on frozen ground. When kicking, a destructive force that can tear a 2-meter thick iron block is applied, increasing destructiveness.

This form's finisher is the Freezing Impact (フリージングインパクト Furījingu Impakuto): Zero-One freezes the enemy before chopping him in two.

Relationships

  • 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.
  • 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.
  • 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.
  • 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.

  • Horobi: TBD
  • 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.

  • Soreo Hiden: 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.
  • Korenosuke Hiden: Aruto's grandfather. As an adult, Aruto inherits Hiden Intelligence from him.

Behind the scenes

Portrayal

Aruto Hiden is portrayed by Fumiya Takahashi (高橋文哉 Takahashi Fumiya). His suit actor is Yuya Nawata (縄田 雄哉 Nawata Yūya), who took over the role as leading suit actor for the main Riders starting with the Reiwa era, succeeding Seiji Takaiwa. Nawata was previously the suit actor for Kamen Rider Genm, Kamen Rider Cronus (Taiga Hanaya), and most recently Kamen Rider Geiz.

Etymology

With "zero" in Japanese and "one" in Japanized-English, Zero-One can be read as Rei Wan (零 ワン) in Japanese, referencing the fact that he is the Kamen Rider of the Reiwa era.

Conception

Main article: Kamen Riders' Concept Art Forms


Notes

  • Zero-One shares similarities with and is possibly a homage to Kamen Rider 1:
    • They are both the first Rider that debut in their representative era.
    • Both have a grasshopper motif.
    • Both of the Riders have the word or numeral "one" in their name.
  • Zero-One Rising Hopper form's pose (after transformation) is similar to Kamen Rider Kuuga's pose[12]
  • Zero-One is the first lead Kamen Rider in over 30 years in a TV series that is entirely themed after a grasshopper, with the last one being Kamen Rider Black RX, not counting the grasshopper legs of Kamen Rider OOO, or the more subtle grasshopper motif of Kamen Rider Double (which is subordinate to his "W" motif and not explicitly identified by his transformation gear).
  • Zero-One is the first main Kamen Rider whose signature color is yellow, excluding Kamen Rider Agito's gold.
  • The name of Zero-One's main form borrows from the first Riders of the two previous eras:
  • Coincidentally, Zero-One's base form and upgrade form use names announced by Decade's K-Touch in a Strongest Form variant for the first two Heisei Riders' Final Forms, Kuuga's Rising Ultimate Form, and Agito's Shining Form.
  • According to the first episode, Aruto is 22 years old, however his actor Fumiya Takahashi is 18 years old.
  • Aruto shares some similarities with Rentaro Kagura and Rento Makina, Kamen Riders who also appeared in Sougo Tokiwa's dream like him.
    • Kamen Rider Shinobi
      • Both of their suits are formed by animal mecha they are based on.
      • Both are shown to be capable of high speed movement.
    • Kamen Rider Kikai
      • Both of their transformations are processed by satellites.
      • Both fight against humanoid robots who tend to take over humanity.
      • Both have black, red, and some form of yellow in their color schemes.
    • Coincidentally, Zero-One's Rising Hopper transformation sound includes three rhyming words like Shinobi and Kikai, as well as Woz and Quiz to another extent (i.e. Authorise! Progrise! To-biaga rise!).
  • Aruto's "failure to make people laugh" gag is similar to Nobuharu UdoIcon-crosswiki from Zyuden Sentai KyoryugerIcon-crosswiki.
  • Zero-One is the only rider to have his armor disfigured instead of being replaced while accessing a new base form.
  • Zero-One's Breaking Mammoth form is the first Mecha form on Reiwa Era and the first since Maximum Gamer and God Maximum Gamer to have a giant Robot as a Mecha Form.
  • Zero-One's Flaming Impact is very similar to Kamen Rider OOO's Gush Cross as it involves them going through a ring before slashing their enemies with their claws.
    • Only difference, OOO had 3 rings while Zero-One had 1 ring.
  • Kamen Rider Zero-One Rising Hopper's color scheme is similar to the Phymateus leprosus or Milkweed Grasshopper, a Toxic Grasshopper that can be found in South Africa.
