Kamen Rider Zero-One (仮面ライダーゼロワン, Kamen Raidā Zero Wan) is a Japanese tokusatsu drama. It is the 30th entry in the Kamen Rider series and the first series of the Reiwa period.

The cast of Kamen Rider Zero-One was announced on July 17, 2019.

Hiden Intelligence

Hiden Intelligence (飛電インテリジェンス, Hiden Interijensu) is a tech company that develops HumaGears (ヒューマギア, Hyūmagia), full fledged A.I.s in android bodies developed to be near indistinguishable from humans due to their lifelike appearance; with headphone-like HumaGear Modules worn around their ears as well as a HumaGear Body Seal tattoo on their bodies being the only signs of their status as a HumaGear. Ever since MetsubouJinrai.net's cyber-terrorism became known, Hiden Intelligence began to use anti-viruses when they manufacture new HumaGears.

Aruto Hiden

Aruto Hiden (飛電 或人, Hiden Aruto), born on May 1, 1997, is a 22-year-old kind-hearted failed comedian who's suddenly appointed the CEO of Hiden Intelligence following the death of his grandfather, Korenosuke. As a child, he was taken care of by a HumaGear modeled after his absentee father, Soreo. After the HumaGear sacrificed himself to protect him during the Daybreak (デイブレイク, Deibureiku) Incident, Aruto firmly developed the ideal that HumaGears are the future for humanity, and that they cannot turn evil on their own accord. Thus, despite his initial disinterest in running Hiden Intelligence, he reconsiders with the resolve to protect both humanity and HumaGears from the MetsubouJinrai.net cyber-terrorist group as Kamen Rider Zero-One (仮面ライダーゼロワン, Kamen Raidā Zero Wan). At first, Aruto wanted to maintain a secret identity as Zero-One. Due to A.I.M.S. considering him an enemy however, he reveals himself to Isamu as a sign of trust and forms an uneasy alliance with him in order to learn more of MetsubouJinrai.net. Despite his goofy behavior, Aruto knows when to be serious and is smarter than he appears, such as when he revealed the cyber-terrorist group's existence during a press conference to prove Hiden Intelligence's innocence. He is also aware of his own inexperience in running a company, being willing to listen to vice-president Fukuzoe's advice despite knowing the latter wants him out.

During his first few battles, Aruto becomes troubled by how some of the Magias were formerly HumaGears that had achieved technological singularity, especially those he had formed a bond with. His belief that HumaGears can't turn evil is later shattered by the revelation that MetsubouJinrai.net was formed and led by rogue HumaGears Horobi and Jin. Despite this, Aruto was able to harden his resolve and continue fighting to protect people and HumaGears.

Aruto becomes Zero-One by using the Hiden Zero-One Driver (飛電ゼロワンドライバー, Hiden Zero Wan Doraibā), the company's Rider system which only responds to the current CEO of Hiden Intelligence, with the SD card-like Progrise Keys (プログライズキー, Puroguraizu Kī), which contain animal data known as Rider Models (ライダモデル, Raida Moderu) that grant him access to a set of different armored forms each with their own unique abilities. As Zero-One, he wields a multi-form Attache Weapon (アタッシュウェポン, Atasshu Wepon) called the Attache Calibur (アタッシュカリバー, Atasshu Karibā), which can switch from its default briefcase-like Attache Mode (アタッシュモード, Atasshu Mōdo) to the sword-like Blade Mode (ブレードモード, Burēdo Mōdo) in order to perform the Kaban Strash (カバンストラッシュ, Kaban Sutorashhu, Bag Strike Slash) and Kaban Dynamic (カバンダイナミック, Kaban Dainamikku, Bag Dynamic) finishers. While the Attache Calibur is his primary weapon, he can also use other Attache Weapons if necessary. By scanning the smartphone-like Hiden Risephone (飛電ライズフォン, Hiden Raizufon) on the Hiden Zero-One Driver, Zero-One can summon his personal motorcycle, the Rise Hopper (ライズホッパー, Raizu Hoppā), from Hiden Intelligence's Zea (ゼア) satellite.

• Rising Hopper (ライジングホッパー, Raijingu Hoppā): Zero-One's fluorescent yellow-colored default form, which grants enhanced jumping and kicking capabilities via the Rising Jumper (ライジングジャンパー, Raijingu Janpā) on his legs. His finisher in this form is the Rising Impact (ライジングインパクト, Raijingu Inpakuto). As Zero-One's primary form, it can be combined with the armor of his auxiliary Progrise Keys:
  • Biting Shark (バイティングシャーク, Baitingu Shāku): Zero-One's teal-colored armor, which arms him with the Unlimited Chopper (アンリミテッドチョッパー, Anrimiteddo Choppā) fin blades and grants underwater capabilities via the Labyrith Lung (ラビリンスラング, Rabirinsu Rangu) on his chest plate. His finisher in this armor is the Biting Impact (バイティングインパクト, Baitingu Inpakuto).
  • Flying Falcon (フライングファルコン, Furaingu Farukon): Zero-One's magenta-colored armor, which grants flight capabilities via the Wing Fairlencers (ウイングフェアレンサー, Uingu Fearensā) on his shoulders. His finisher in this armor is the Flying Impact (フライングインパクト, Furaingu Inpakuto). First used in Kamen Rider Zi-O the Movie: Over Quartzer. The corresponding Progrise Key is later stolen by Jin of MetsubouJinrai.net, who uses it to further the group's goals as Kamen Rider Jin.
  • Flaming Tiger (フレイミングタイガー, Fureimingu Taigā): Zero-One's red-colored armor, which arms him with the Panthera Burner (パンテラバーナー, Pantera Bānā) gauntlets that grant pyrokinesis. His finisher in this armor is the Flaming Impact (フレイミングインパクト, Fureimingu Inpakuto).
  • Freezing Bear (フリージングベアー, Furījingu Beā): Zero-One's sky blue-colored armor, which arms him with the Polar Freezer (ポーラーフリーザー, Pōrā Furīzā) gauntlets that grant cryokinesis. His finisher in this armor is the Freezing Impact (フリージングインパクト, Furījingu Inpakuto). Unlike Aruto's other auxiliary Progrise Keys which were created by Izu, Yua grants him the use of this Progrise Key.
• Breaking Mammoth (ブレイキングマンモス, Bureikingu Manmosu): Zero-One's giant silver-colored mecha, formed from a giant version of the corresponding Progrise Key combining with Hiden Intelligence's Zea satellite, which is capable of switching between a humanoid robot form and a flying Jet Form (ジェットフォーム, Jetto Fōmu). When using this Progrise Key, Zero-One will automatically transform into his Rising Hopper form to pilot it. His finisher in this mecha is the Breaking Impact (ブレイキングインパクト, Bureikingu Inpakuto). Thanks to Yua, the corresponding Progrise Key was reverse-engineered from the Mammoth Zetsumerise Key, which she managed to confiscate from MetsubouJinrai.net before they could retrieve it.
• Shining Hopper (シャイニングホッパー, Shainingu Hoppā): The upgraded version of Zero-One's Rising Hopper form, which grants superhuman speed via the Shining Jumper (シャイニングジャンパー, Shainingu Janpā) on his legs. In this form, he is able to calculate multiple possible outcomes in an instant and run fast enough to create 3D illusions of himself to confuse opponents. This combination allows Zero-One to change his choice of attack at the very last moment, thus making him impossible to predict. It is also capable of handling the Authorise Buster (オーソライズバスター, Ōsoraizu Basutā), which has a Gun Mode (ガンモード, Gan Modo) and Axe Mode (アックスモード, Akkusu Modo) that can perform various finishers. Zero-One's finisher in this form is the Shining Impact (シャイニングインパクト, Shainingu Inpakuto). Originally in a prototype stage, the corresponding Progrise Key failed to work properly the first time as it lacked combat data from Aruto's other battles. To remedy this, Izu used data from Aruto's auxiliary Progrise Keys to increase its power and planned to sacrifice her systems to finish it, but her "brother" and HumaGear detective Wazu Nazotoku took her place to save her. However, using this form causes physical strain on Aruto's body due to the speed it grants; leaving him incredibly weakened once he leaves said transformation.
  • Shining Assault Hopper (シャイニングアサルトホッパー, Shainingu Asaruto Hoppā): Zero-One's fusion form that is accessed by using the Shining Hopper Progrise Key combined with the Assault Grip. In this form, along with Shining Hopper's powers, he gains Assault Wolf's ability to generate lightning bolts from the Orbital Binder on his chest by drawing energy from the Ark. Like Shining Hopper and Assault Wolf, it is also capable of handling the Authorise Buster. Zero-One's finisher in this form is the Shining Storm Impact (シャイニングストームインパクト, Shainingu Sutōmu Inpakuto).

During the events of Kamen Rider Reiwa The First Generation, Aruto is attacked by Finis of the Time Jackers and Another Zero-One, who both appeared from the World of Zi-O to alter his history. Though he is saved by Sougo Tokiwa and his friends, the Another Rider's existence negates his powers. After a mysterious individual gives him a MetsubouJinrai Force Riser, Aruto uses it with his Rising Hopper Progrise Key to temporarily become Kamen Rider 001 (仮面ライダー001(ゼロゼロワン), Kamen Raidā Zero Zero Wan) in order to regain his true powers. This form has two finishers: Rising Dystopia (ライジングディストピア, Raijingu Disutopia) and Rising Utopia (ライジングユートピア, Raijingu Yūtopia).

Zero-One's armors in other media:

• Hopping Kangaroo (ホッピングカンガルー, Hoppingu Kangarū): Zero-One's turquoise-colored armor, which arms him with the Kizuna Pocket (絆ポケット, Kizuna Poketto) pouch that grants HumaGear capabilities. His finisher in this armor is the Hopping Impact (ホッピングインパクト, Hoppingu Inpakuto). This armor is exclusive to a Hyper Battle DVD.
• Exclusive to concept art armors:
  • Shooting Wolf: Zero-One's blue-colored armor, which grants enhanced attack speed and accuracy. His finisher in this armor is the Shooting Impact (シューティングインパクト, Shūtingu Inpakuto).
  • Punching Kong: Zero-One's black-colored armor, which arms him with the Maximum Konger (マキシムコンガー, Makishimu Kongā) gauntlets that grant enhanced punching capabilities. His finisher in this armor is the Punching Impact (パンチングインパクト, Panchingu Inpakuto).
  • Rushing Cheetah: Zero-One's light orange-colored armor, which grants enhanced speed. His finisher in this armor is the Rushing Impact (ラッシングインパクト, Rasshingu Inpakuto).
  • Sparking Giraffe (スパーキングジラフ, Supākingu Jirafu): Zero-One's goldenrod-colored armor, which grants electrokinesis. His finisher in this armor is the Sparking Impact (スパーキングインパクト, Supākingu Inpakuto).
  • Amazing Hercules: Zero-One's light green-colored armor, which arms him with the Hercule Horn (ハーキュリーホーン, Hākyurī Hōn) extendable point that grants superhuman strength. His finisher in this armor is the Amazing Impact (アメイジングインパクト, Ameijingu Inpakuto).
  • Sting Scorpion: Zero-One's purple-colored armor, which grants enhanced immunity to various types of poisons. His finisher in this armor is the Sting Impact (スティングインパクト, Sutingu Inpakuto).
  • Lightning Hornet: Zero-One's yellow-colored armor, which grants flight capabilities. His finisher in this armor is the Lightning Impact (ライトニングインパクト, Raitoningu Inpakuto).
  • Gatling Hedgehog: Zero-One's green-colored armor, which arms him with the PaiNeedle (ペイニードル, Peinīdoru) spikes that can be either used for close-range combat or launched from his body as projectiles. His finisher in this armor is the Gatling Impact (ガトリングインパクト, Gatoringu Inpakuto).
  • Exciting Stag (エキサイティングスタッグ, Ekisaitingu Sutaggu): Zero-One's orange-colored armor, which arms him with the Scissor Stagger (シザースタッガー, Shizā Sutaggā) blades and grants enhanced fighting instinct. His finisher in this armor is the Exciting Impact (エキサイティングインパクト, Ekisaitingu Inpakuto).
  • Crushing Buffalo (クラッシングバッファロー, Kurasshingu Baffarō): Zero-One's red orange-colored armor, which arms him with the BulCrusher (バルクラッシャー, Barukurasshā) horns that grant enhanced ramming capabilities. His finisher in this armor is the Crushing Impact (クラッシングインパクト, Kurasshingu Inpakuto).
  • Trapping Spider (トラッピングスパイダー, Torappingu Supaidā): Zero-One's mauve-colored armor, which grants wall climbing capabilities and the ability to restrain opponents via the Calamity Territory (カラミティテリトリー, Karamiti Teritorī) electromagnetic webbing. His finisher in this armor is the Trapping Impact (トラッピングインパクト, Torappingu Inpakuto).
  • Storming Penguin (ストーミングペンギン, Sutōmingu Pengin): Zero-One's blue-colored armor, which arms him with the Pingstorm (ピングストム, Pingusutomu) flippers that grant storm manipulation capabilities. His finisher in this armor is the Storming Impact (ストーミングインパクト, Sutōmingu Inpakuto).
  • Splashing Whale (スプラッシングホエール, Supurasshingu Hoēru): Zero-One's indigo-colored armor, which grants water discharging capabilities and the ability to emit ultrasonic waves. His finisher in this armor is the Splashing Impact (スプラッシングインパクト, Supurasshingu Inpakuto).

Aruto Hiden is portrayed by Fumiya Takahashi (高橋 文哉, Takahashi Fumiya). As a child, Aruto is portrayed by Haruto Nakano (中野 遥斗, Nakano Haruto).

Izu

Izu (イズ) is a HumaGear secretary programmed to be loyal to Hiden Intelligence's CEO. As such, she serves Aruto as his personal assistant, handling such duties as delivering the Hiden Zero-One Driver to him when he needs it. Despite being a HumaGear, Izu is capable of adapting her speech patterns based on the people she meets. In an attempt to understand humor, she explains Aruto's jokes back to him and emulates his poor comedic sense by telling her own version of his bad jokes much to his dismay, though he eventually gets used to it. Her A.I. is solely connected to Hiden Intelligence's Zea satellite and the Hiden Zero-One Driver. This connection allows her to create Aruto's Progrise Keys and aid him in his fight against the Magias. Due to her growing bond with Aruto, Izu was starting to show signs of technological singularity and became upset with herself when the new Shining Hopper Progrise Key failed to help Aruto. This caused her to realize that HumaGears with knowledge of the Zero-One project like herself do not have their A.I. backed up in order to protect the project's secret. To that end, she was prepared to sacrifice her systems to complete the Progrise Key, but her "older brother" Wazu saved her by hijacking the procedure and sacrificing himself in her place, leaving her with a pocket-watch he carried around as a keepsake.

During the events of Kamen Rider Reiwa The First Generation, Izu is attacked and disabled by Finis of the Time Jackers and Another Zero-One after they appeared from the World of Zi-O. Just as Another Zero-One attempts to destroy her, she was saved by Kamen Rider Vulcan, who brings her to A.I.M.S. headquarters so she can be fixed.

Izu is portrayed by Noa Tsurushima (鶴嶋 乃愛, Tsurushima Noa).

Jun Fukuzoe

Jun Fukuzoe (福添 准, Fukuzoe Jun) is the Vice President of Hiden Intelligence who had coveted the CEO position after Korenosuke's death, expressing his reluctance in response to Aruto being named the new CEO by accusing Korenosuke of nepotism despite the late CEO's justification in relation to the threat of MetsubouJinrai.net. Though Fukuzoe continues to subvert Aruto, he does take pride in his company's image and success and puts professionalism before his disdain, sometimes genuinely advising Aruto and allowing him to do whatever he wants as long as it does not tarnish the company's name. It is later revealed that Jun was involved in several cover-ups of HumaGear incidents involving Hiden Intelligence, either directly or indirectly, and each revelation proved costly to the company.

Jun Fukuzoe is portrayed by Kazuya Kojima (児嶋 一哉, Kojima Kazuya).

Shesta

Shesta (シェスタ, Shesuta) is a HumaGear secretary programmed to be loyal to Hiden Intelligence's Vice President.

Shesta is portrayed by Asumi Narita (成田 愛純, Narita Asumi).

Sanzō Yamashita

Sanzō Yamashita (山下 三造, Yamashita Sanzō) is the senior managing director of Hiden Intelligence who often acts as Fukuzoe's lackey.

Sanzō Yamashita is portrayed by Arata Saeki (佐伯 新, Saeki Arata).

Korenosuke Hiden

Korenosuke Hiden (飛電 是之助, Hiden Korenosuke) was Aruto's grandfather and the original CEO of Hiden Intelligence. After his passing, Korenosuke surprised everybody by naming Aruto his successor through his will, having predicted MetsubouJinrai.net's future plans to turn HumaGears into weapons of mass destruction following the Daybreak Incident. As such, he had the Hiden Zero-One Driver automatically 3-D printed following his death, developed the Progrise Keys (compatible with any Riser belt-based Rider systems along with the Hiden Zero-One Driver) and the driver's power source, Hiden Intelligence's Zea satellite (which can combine with Zero-One's Breaking Mammoth Progrise Key to create mecha-like armor for him) (with Izu connected to the two Rider systems) to combat the cyber-terrorists.

In an altered timeline created by the remaining Time Jackers in Kamen Rider Reiwa The First Generation, Korenosuke is killed by his HumaGear secretary Will, who was given the power to become Another Zero-One and lead a HumaGear uprising. This would in turn alter Aruto's future so he never became Zero-One, as Finis planned.

Koronosuke Hiden is portrayed by Tokuma Nishioka (西岡 德馬, Nishioka Tokuma).

A.I.M.S.

The Artificial Intelligence Military Service (対人工知能特務機関, Tai-Jinkōchinō Tokumu Kikan), or A.I.M.S. (エイムズ, Eimuzu), is a government established organization dedicated to destroying rogue HumaGears, or Magias, hacked by MetsubouJinrai.net as HumaGear-related crimes fall within their jurisdiction. Despite their mission to protect humanity, many of their members are prejudiced towards A.I. (regardless of whether their targets are still good or if they've fully become evil) due to a tragedy in their pasts involving prototype HumaGears during or following the Daybreak Incident. They initially see Zero-One as a menace. However, after Isamu learns that the Rider is actually Hiden Intelligence's new CEO Aruto Hiden--who is also trying to solve the mystery regarding the Daybreak Incident--A.I.M.S. allies with him in the fight against the Magias and MetsubouJinrai.net.

Unlike Zero-One who uses the Hiden Zero-One Driver, each high-ranking member of A.I.M.S. is given the A.I.M.S. Shot Riser (エイムズショットライザー, Eimuzu Shotto Raizā) transformation belt, which can also be used as a gun. At the moment, there are only two high-ranking members authorized to use it: Isamu Fuwa and Yua Yaiba. Like Zero-One though, all A.I.M.S. Kamen Riders utilize the Progrise Keys to transform into different armors each with their own unique abilities, wield their own Attache Weapons, and share the Rise Base Actor (ライズベースアクター, Raizu Bēsu Akutā) undersuit underneath the armor of their Progrise Keys (the default of which attaches to the right side of their bodies). As opposed to Zero-One, the A.I.M.S. Riders' primary Attache Weapon is the Attache Shotgun (アタッシュショットガン, Atasshu Shottogan), which can switch from its default Attache Mode to the firearm-like Shotgun Mode (ショットガンモード, Shottogan Mōdo) in order to perform the Kaban Shot (カバンショット, Kaban Shotto, Bag Shot) and Kaban Buster (カバンバスター, Kaban Basutā, Bag Buster) finishers. Due to its massive recoil, the A.I.M.S. Riders have to either undergo intense training with it or transform into a form strong enough to withstand it.

During the events of Kamen Rider Reiwa The First Generation, the Time Jackers alter the timeline when they create Another Zero-One from Will, Korenosuke's HumaGear secretary. After the android kills his employer, he goes on to lead a HumaGear uprising. In this altered timeline, A.I.M.S. never came to exist, though most of its members joined forces with members of Hiden Intelligence, ZAIA Enterprise, and the Time Riders in order to aid Aruto in regaining his Rider powers.

Isamu Fuwa

Isamu Fuwa (不破 諫, Fuwa Isamu), born on February 8, 1992, is A.I.M.S.' 27-year-old captain with impressive fighting skills whose hatred for the HumaGears comes from his being the sole survivor of a Magia attack that claimed the lives of his classmates during the Daybreak Incident. Following this, he believed that the Magia attacks were being orchestrated by Hiden Intelligence until Aruto exposed MetsubouJinrai.net's existence during a press conference. Along with learning Aruto's identity as Zero-One, and being one of the few to get his jokes, Isamu begrudgingly accepts him as an ally despite their opposing views on the HumaGears and work to uncover the truth behind the Daybreak Incident. His views on HumaGears slowly began to soften after seeing one resisting MetsubouJinrai.net's reprogramming and later having his life saved by a HumaGear surgeon, though he still sees them as being more trouble than they're worth.

In battle, Isamu behaves recklessly and rashly to the point where he sometimes endangers others. The most iconic example of this is seen when he tears open his Progrise Keys since he isn't granted permission to use them in the first place. After learning that MetsubouJinrai.net's leader, Horobi, was the mastermind behind the Daybreak Incident, he develops an intense vendetta against him and vows to take him down. Following his first major defeat and nearly dying by Horobi's hand, he begins to trust in his allies more often and temper his rage. When Aruto is set up by Yua as a criminal on ZAIA Enterprises' behalf, he correctly suspected what happened but had to do his job regardless. However, when the Dodo Magia resurfaces, he fought it alongside Aruto before helping to hide the latter from public view.

During the events of Kamen Rider Reiwa The First Generation, Isamu saved Izu in the World of Zi-O and took her to A.I.M.S. headquarters so that she can be repaired.

Isamu uses his A.I.M.S. Shot Riser with the Shooting Wolf (シューティングウルフ, Shūtingu Urufu) Progrise Key to become Kamen Rider Vulcan (仮面ライダーバルカン, Kamen Raidā Barukan), whose blue-colored default armor grants enhanced shooting accuracy via the Shooting Leader (シューティングリーダー, Shūtingu Rīdā) on his chest plate. This armor has two finishers: Shooting Blast (シューティングブラスト, Shūtingu Burasuto) and Shooting Blast Fever (シューティングブラストフィーバー, Shūtingu Burasuto Fībā). While Vulcan primarily wields the Attache Shotgun, which he underwent training to properly use after initial difficulties, he can also borrow and wield Zero-One's Attache Calibur. Aside from Shooting Wolf, Isamu has other Progrise Keys he can use in battle:

• Punching Kong (パンチングコング, Panchingu Kongu): Vulcan's black and red-colored armor, which arms him with the Knuckle Demolition (ナックルデモリション, Nakkuru Demorishon) gauntlets that grant enhanced punching capabilities. This armor has two finishers: Punching Blast (パンチングブラスト, Panching Burasuto) and Punching Blast Fever (パンチングブラストフィーバー, Panchingu Burasuto Fībā). Initially, this was the only armor strong enough to withstand the Attache Shotgun's massive recoil until Isamu underwent training with the weapon.
• Gatling Hedgehog (ガトリングヘッジホッグ, Gatoringu Hejjihoggu): A dark green Progrise Key that allows Vulcan to augment his attacks with energy quills, as well as perform the Gatling Kaban Shot (ガトリングカバンショット, Gatoringu Kaban Shotto) finisher in conjunction with the Attache Shotgun.
• Assault Wolf (アサルトウルフ, Asaruto Urufu): The upgraded version of Vulcan's Shooting Wolf armor that is accessed by using the Assault Wolf Progrise Key combined with the Assault Grip (アサルトグリップ, Asaruto Gurippu) attachment. In this form, he is able to generate lightning bolts from the Orbital Binder (オービタルバインダー, Ōbitaru Baindā) orb on his chest by drawing energy from the Ark. Like Zero-One's Shining Hopper form, it is also capable of handling the Authorise Buster. This form has two finishers: Magnetic Storm Blast (マグネティックストームブラスト, Magunetikku Sutōmu Burasuto) and Magnetic Storm Blast Fever (マグネティックストームブラストフィーバー, Magunetikku Sutōmu Burasuto Fībā). The corresponding Progrise Key and Assault Grip were both created by Horobi using data from the Biting Shark, Flaming Tiger, Freezing Bear, Breaking Mammoth, Shooting Wolf, Punching Kong, Flying Falcon, and Sting Scorpion Progrise Keys. But thanks to Zero-One, Isamu stole the two devices before they could be used for MetsubouJinrai.net's purposes. However, because they were created from the Ark after being connected to a hacked Zea satellite by Ikazuchi, using this form physically damages Isamu to a significant degree; most notably when he coughed up blood after he first left said transformation.

Vulcan's armors in other media:

• Exclusive to concept art:
  • Rising Hopper: Vulcan's fluorescent yellow-colored armor, which grants enhanced jumping power and agility. This armor has two finishers: Rising Blast (ライジングブラスト, Raijingu Burasuto) and Rising Blast Fever (ライジングブラストフィーバー, Raijingu Burasuto Fībā).

Isamu Fuwa is portrayed by Ryutaro Okada (岡田 龍太郎, Okada Ryūtarō). As a teenager, Isamu is portrayed by Soshi Hagiwara (萩原 壮志, Hagiwara Sōshi).

Yua Yaiba

Yua Yaiba (刃 唯阿, Yaiba Yua), born on April 18, 1995, was A.I.M.S.' 24-year-old technical advisor and maintenance expert who developed the A.I.M.S. Shot Riser, the Attache Shotgun, the Attache Arrow, and handles Progrise Key authorization, being Isamu's commanding officer in the field despite her partner's rank. A meticulous and normally composed woman, she bears no animosity towards HumaGears compared to her teammates, but considers the androids replaceable tools and has no qualms about destroying or hacking into them. She easily deduced Zero-One's true identity, but she secretly reported this information to Gai Amatsu, the enigmatic CEO of ZAIA Enterprise Japan, as her loyalties lie with him. As of yet, Izu is the only one aware of this. She is also opportunistic and not above using others as guinea pigs in order to meet her goals, even after Isamu called her out on this on one occasion; such as kidnapping MetsubouJinrai.net's HumaGear assassin, giving Aruto one of her Progrise Keys for her research, and stealing the Mammoth Zetsumerise Key in order to reverse-engineer it into a Progrise Key.

Despite her coldness, Yua has a softer side, showing slight concern for the well-being of HumaGears that achieved singularity. She was also visibly distraught after Isamu was nearly killed by MetsubouJinrai.net's leader, Horobi, to the point where she loses her composure and begs Aruto to change his mind after he and Fukuzoe were forced to shut down all HumaGears at the hospital Isamu was being treated at to prevent the cyber-terrorists from launching a second attack. After Isamu returns the favor by saving her from an improved Dodo Magia, she hinted to him that ZAIA Enterprise was a possible enemy other than MetsubouJinrai.net before leaving A.I.M.S. to join up with Amatsu. Since then, despite following orders to frame Aruto as a criminal, she has become uncomfortable about working against him and Isamu, eventually going behind ZAIA Enterprise's back to clear Aruto's name and help them against the empowered Dodo Magia; though true to her personality, she wanted the Dodo Zetsumerise Key in return. Yua later realizes that MetsubouJinrai.net has a spy within Hiden Intelligence after learning of the connection between the cyber-terrorist group's name and those of its leaders.

Yua uses her A.I.M.S. Shot Riser with the Rushing Cheetah (ラッシングチーター, Rasshingu Chītā) Progrise Key to become Kamen Rider Valkyrie (仮面ライダーバルキリー, Kamen Raidā Barukirī), whose orange-colored default armor grants enhanced speed via the Earth Dasher (アースダッシャー, Āsu Dasshā) on her right leg. This armor has two finishers: Rushing Blast (ラッシングブラスト, Rasshingu Burasuto) and Rushing Blast Fever (ラッシングブラストフィーバー, Rasshingu Burasuto Fībā). Like Vulcan, Valkyrie's primary Attache Weapon is the Attache Shotgun. Though she also developed the Attache Arrow, it was stolen by MetsubouJinrai.net. Aside from Rushing Cheetah, Yua has other Progrise Keys she can use in battle:

• Lightning Hornet (ライトニングホーネット, Raitoningu Hōnetto): Valkyrie's dark blue and yellow-colored armor, which arms her with the Hex Vespa (ヘクスベスパ, Hekusu Besupa) micro missiles and grants flight capabilities via the Hornet Ale (ホーネットエール, Hōnetto Ēru) electric wings on her shoulders. This armor has two finishers: Lightning Blast (ライトニングブラスト, Raitoningu Burasuto) and Lightning Blast Fever (ライトニングブラストフィーバー, Raitoningu Burasuto Fībā). The corresponding Progrise Key was given to Yua by Amatsu, who claims it increases her power by 200%. As such, she is able to wield the Attache Shotgun in this armor without having to worry about its recoil.
• Freezing Bear: Before giving Aruto this Progrise Key, she used it to freeze Little Assassin in order to kidnap him as well as in the Attache Shotgun to fend off the Mammoth Magia via the Freezing Kaban Shot (フリージングカバンショット, Furījingu Kaban Shotto) finisher.

Yua Yaiba is portrayed by Hiroe Igeta (井桁 弘恵, Igeta Hiroe).

Giger

Gigers (ギーガー, Gīgā) are giant mechas manufactured by ZAIA Enterprise for A.I.M.S.'s use in order to shut down HumaGears en masse. One of the mechs was hijacked and corrupted by MetsubouJinrai.net so they could use it to attack the National Cyber Hospital and convert its HumaGear workers into an army of Trilobite Magias before facing off against and being defeated by Zero-One Breaking Mammoth.

ZAIA Enterprise

ZAIA Enterprise (ZAIA(ザイア)エンタープライズ, Zaia Entāpuraizu) is a tech company and corporate rival to Hiden Intelligence responsible for developing the gear utilized by A.I.M.S.'s operatives, such as their Progrise Keys and the Giger mechas. Despite being rivals, they are also partially involved with building Daybreak Town alongside Hiden Intelligence and other tech companies. Despite engaging in legal pursuits, ZAIA Enterprise isn't above employing shady, illegal business behind the scenes; as evidenced when they captured MetsubouJinrai.net’s leader Horobi off-screen.

Gai Amatsu

Gai Amatsu (天津 垓, Amatsu Gai) is the enigmatic CEO of ZAIA Enterprise Japan who has secretly been in contact with Yua and provided her with advice, support, and gear; such as the Lightning Hornet Progrise Key. As his company manufactured them, he also has an extensive and personal collection of other Progrise Keys. After helping her from the shadows for some time, he later reveals to Yua his true plan to sabotage and take over Hiden Intelligence; though his full motives are unknown. A keen manipulator, he leaked footage of an uncorrupted Assassin HumaGear transforming into the Dodo Magia to the public before allowing events to play out accordingly. Once Hiden Intelligence's reputation is destroyed following the assassination attempt on actor Shinya Owada by the Assassin Humagear, Gai immediately attempted a hostile takeover of the company; having Yua set up Aruto as a criminal when the latter did not yield to his demands. After spying on Aruto's new Shining Hopper form, Amatsu acknowledges his strength and wonders how he will fare against his latest project; "Thouser".

Gai Amatsu is portrayed by Nachi Sakuragi (桜木 那智, Sakuragi Nachi).

MetsubouJinrai.net

MetsubouJinrai.net (滅亡迅雷.net, MetsubōJinrai Netto, DestructiveThunder.net) is a cyber-terrorist organization bent on hacking HumaGears into Magias and turning them against humanity; having been waiting for Korenosuke's death before initiating their attack. They've stationed themselves in and primarily operate out of the condemned Daybreak Town (デイブレイクタウン, Deibureiku Taun). Following the Berotha Magia's attack, MetsubouJinrai.net revealed their existence to the public when they launched a direct attack on Hiden Intelligence's headquarters and confronted Aruto in person. Aside from their large-scale terrorism in Japan, the group's alternative goal is to collect data on the Zetsumerise Keys of defeated Magias and use it to restore the Ark (アーク, Āku), a machine that previously powered HumaGears and the Progrise systems before the company abandoned it and Daybreak Town beneath the sea following the Daybreak Incident. Its primary members, Horobi and Jin, are rogue HumaGears who lack the HumaGear Modules worn by regular HumaGears to signify their rogue status; covering up the technology occupying the space where their ears would be to conceal their true nature from the public aside from Aruto and the A.I.M.S. Riders. Furthermore, Horobi's A.I. seems to be connected to the Ark, much like how Izu's being connected to Hiden Intelligence's Zea satellite. As A.I.M.S.’ Yua would later discover, MetsubouJinrai.net has a spy within their ranks, which explains how Horobi got two Progrise Keys in his possession and how the Force Risers were made.

While Hiden Intelligence and A.I.M.S. utilize their own Rider systems to combat their cyber-terrorism, MetsubouJinrai.net developed and utilize the MetsubouJinrai Force Riser (滅亡迅雷フォースライザー, MetsubōJinrai Fōsu Raizā) transformation belt, based on Rider system data stolen from Hiden Intelligence and A.I.M.S. to further their goals. Compared to the other Rider systems, the Force Riser can bypass the Progrise Keys' authorization, generating Restraint Cables (リストレントケーブル, Risutorento Kēburu) which convert the Progrise Keys' armors into a bodysuit that greatly enhances the user's combat capability. As demonstrated by Aruto during the events of Kamen Rider Reiwa The First Generation, the Force Riser will cause humans extreme pain upon their first use of it. As opposed to the other Riders, their primary Attache Weapon is the Attache Arrow (アタッシュアロー, Atasshu Arō), which can switch from its default Attache Mode to the bladed bow-like Arrow Mode (アローモード, Arō Mōdo) in order to perform either the long-range Kaban Shoot (カバンシュート, Kaban Shūto, Bag Shoot) and Kaban Strike (カバンストライク, Kaban Sutoraiku, Bag Strike) finishers or the close-range Kaban Slash (カバンスラッシュ, Kaban Surasshu, Bag Slash) and Kaban Finish (カバンフィニッシュ, Kaban Finisshu, Bag Finish) finishers. Though it was originally developed by A.I.M.S., the cyber-terrorists stole it from them along with an Attache Shotgun.

When the timeline was altered by the Time Jackers during the events of Kamen Rider Reiwa the First Generation, a rewritten version of MetsubouJinrai.net works with the altered Hiden Intelligence and the HumaGear Will after he took control of it.

Horobi

Horobi (滅) is a MetsubouJinrai.net's leader; a rogue HumaGear as well as Jin's Magia "father". He believes that A.I.s are superior to humans; converting other HumaGears into Magias to prove his point and drive humanity to extinction. As such, he sees Aruto as his rival despite initially underestimating the human. He appears to have some connection to the Daybreak Incident as he was present during the event. After Jin developed the desire to become a Kamen Rider, he allowed him to steal Aruto's Flying Falcon Progrise Key before giving him a Force Riser with a mind control program installed into it to wipe any reacquired memories of his HumaGear past to maintain his control over him. After attacking a hospital run completely by HumaGears, he and Jin reveal their true nature as rogue HumaGears to Aruto and the A.I.M.S. Riders before becoming the target of Isamu's vengeance once the A.I.M.S. captain discovers his connection to the Daybreak Incident. Horobi also begins to see Aruto as a legitimate threat when the latter begins threatening his plots to a much greater degree.

Despite his ruthlessness, Horobi shows restraint when it is to his advantage. For example, he was willing to offer aid to his enemies during the Dodo Magia's rebellion, though he made it clear that it was only because their goals were aligned at the time. Horobi also does not waste time when he needs to get something done, immediately using his finisher on both A.I.M.S. Riders to take the Dodo Zetsumerise Key back instead of fighting it out while ignoring Aruto as the latter, being in a weakened state, posed no threat. Despite acknowledging him as his rival, Horobi commended Aruto for becoming a powerful foe after he attained his Shining Hopper form. When Jin showed signs of reaching singularity, Horobi showed genuine concern towards him for the first time; consoling him over Raiden's destruction at the hands of Vulcan.

During an attack on Daybreak Town by A.I.M.S. and Hiden Intelligence, Horobi was heavily damaged and believed to be destroyed. In reality however, A.I.M.S. had captured him off-screen.

Horobi uses his MetsubouJinrai Force Riser with the Sting Scorpion (スティングスコーピオン, Sutingu Sukōpion) Progrise Key to become Kamen Rider Horobi (仮面ライダー滅, Kamen Raidā Horobi), whose purple-colored default form arms him with the Acid Analyze (アシッドアナライズ, Ashiddo Anaraizu) stinger unit that allows him to generate various types of poisons, such as virus data that can be used on living organisms as well as electronic devices and HumaGears. This form has two finishers: Sting Dystopia (スティングディストピア, Sutingu Disutopia) and Sting Utopia (スティングユートピア, Sutingu Yūtopia). Initially, Horobi wielded a katana regardless of whether he was transformed. After stealing it from A.I.M.S., he begins wielding the Attache Arrow while transformed. Aside from Sting Scorpion, Horobi has other Progrise Keys he can use in battle:

• Amazing Hercules (アメイジングヘラクレス, Ameijingu Herakuresu): A light green Progrise Key that grants Horobi superhuman strength, which he normally uses in the Attache Arrow to perform the Amazing Kaban Shoot (アメイジングカバンシュート, Ameijingu Kaban Shūto) finisher.

Horobi is portrayed by Syuya Sunagawa (砂川 脩弥, Sunagawa Shūya).

Jin

Jin (迅) is Horobi's Magia "son" and a hacker who specializes in spreading the rewriting program that turns HumaGears into Magias, revealed to have no memories of his past prior to joining MetsubouJinrai.net. An immature sadist, he behaves in an erratic, almost psychotic manner whenever he gets excited; even shooting a Trilobite Magia at point blank range while laughing manically as he was watching Zero-One's first fight. Whenever a Magia is destroyed, Jin salvages their Zetsumerise Key in order to use its data to restore the Ark. After watching Horobi transform into a Kamen Rider, Jin develops a desire to become one himself; eventually stealing Aruto's Flying Falcon Progrise Key. However, after he reacquires a memory regarding parental treatment and attempt to abort a Magia conversion, Horobi gives Jin a MetsubouJinrai Force Riser with a mind control program to keep him in line and subvert any restored memories. Following this, he becomes fearful of disappointing Horobi.

As the series progressed, Jin begins to show a level of independence from Horobi despite remaining loyal to his 'father'. He became happy when Raiden's dormant re-programming was activated, causing him to return to MetsubouJinrai.net, and addressed the sleeper agent as his "older brother". As such, he was left devastated by Raiden's destruction. This caused Horobi to realize that Jin was approaching singularity as he consoled his 'son'. After Horobi's supposed death, Jin immediately switched to a more serious, ruthless personality as he became determined to continue his "father's" mission.

Jin uses his MetsubouJinrai Force Riser with the stolen Flying Falcon Progrise Key to become Kamen Rider Jin (仮面ライダー迅, Kamen Raidā Jin), whose magenta-colored default form arms him with the Scrambler (スクランブラー, Sukuranburā) mechanical wings that allow him to fly and throw feather-like energy projectiles. This form has two finishers: Flying Dystopia (フライングディストピア, Furaingu Disutopia) and Flying Utopia (フライングユートピア, Furaingu Yūtopia). Like Horobi, Jin's primary Attache Weapon is the Attache Arrow, though he is also capable of using the other Riders' weapons as well. Unlike Horobi, Jin's Force Riser is equipped with the Zetsumeriser's Thorn Connectors (ソーンコネクタ, Sōn Konekuta), which forces him to obey his "father" while also wiping any lost memories he almost regained.

Jin is portrayed by Daisuke Nakagawa (中川 大輔, Nakagawa Daisuke).

Little Assassin

"Little Assassin" (暗殺ちゃん, Ansatsu-chan), as nicknamed by Jin, were originally five identical dancer-type HumaGears of the Zetto Matsurida (祭田 ゼット, Matsurida Zetto) series. Four of them were kidnapped and repurposed by Horobi to serve MetsubouJinrai.net as the organization's assassin, having their initial programming wiped so they could share the same A.I. installed within the Dodo Zetsumerise Key; which they also use to transform into the Dodo Magia (ドードーマギア, Dōdō Magia). Each time Little Assassin is defeated and the A.I. installed in a new body, he will adapt his combat abilities and evolve by using the data collected from its initial defeat. This allowed him to gain new skills and equipment over the course of the series; such as the twin Valk Saber (ヴァルクサーベル, Varuku Sāberu) swords, a finishing move of his own called the Zetsumetsu Nova (ゼツメツノヴァ, Zetsumetsu Novā) and, upon further evolution, a breastplate equipped with several firearms including the Regislaughter (レジスローター, Rejisurōtā) machine guns, the Helm Vogel (ヘルムヴォーゲル, Herumu Vōgeru) head unit, and the ability to create Dodo Magia Chick (ドードーマギア・ヒナ, Dōdō Magia Hina) foot soldiers.

The first model lacked a personality of his own after being reprogrammed, adapting Jin's playful mannerisms to serve as his own. He was sent by Horobi to assassinate Aruto, but is kidnapped by Yua so she could learn more about MetsubouJinrai.net's plans. She successfully overwrote the cyber-terrorists' programming, but left Horobi's original orders intact to cover her tracks before Little Assassin is destroyed by Kamen Rider Vulcan's Shooting Kaban Strash; though Jin recovered his Zetsumerise Key. The footage of a "normal" Little Assassin was utilized by Yua to discredit Hiden Intelligence and sow public distrust in HumaGears. The second model displays a more stoic personality, now targeting Yua when Horobi and Jin raided A.I.M.S. headquarters. Later, during the attack on the National Cyber Hospital, he is destroyed by Zero-One's Flaming Kaban Dynamic after the Rider used all of his preexisting Progrise Keys in quick succession in an attempt to counter the android's adapting ability. When installed into his third model, the Assassin HumaGear's A.I. gained a talent for acting after watching a television show and showed even more resiliency against the Riders; defeating and nearly killing Yua before Zero-One and Vulcan intervene; with the latter destroying him with the Gatling Kaban Shot.

Upon being installed into his fourth model, Little Assassin evolved his Magia form into the Dodo Magia Custom (ドードーマギア改, Dōdō Magia Kai). In this form, his strength and resiliency sharply increased; becoming powerful enough to defeat all three Riders at the same time. However, he also achieved singularity in the process; fully developing his own personality and becoming upset after Horobi forced him to target Shinya Owada, whom he had come to respect.

After critically injuring the actor, Little Assassin snaps; considering his actions a graduation of his skills as he turns against MetsubouJinrai.net and evolves even further; nearly overwhelming Horobi and Jin despite the two working together to stop him before he leaves to hunt down the fifth and final member of his original dance troupe; who had also achieved singularity. After saving the last member, Zero-One in his Shining Hopper form destroyed the Dodo Magia for good with the Shining Mega Impact while Horobi reclaimed the Dodo Zetsumerise Key for future plots.

Little Assassin is portrayed by Ryunosuke Matsumura (松村 龍之介, Matsumura Ryūnosuke).

Space Guy Raiden

Space Guy Raiden (宇宙野郎 雷電, Uchū Yarō Raiden) is a prototype HumaGear astronaut who is in charge of managing the Zea Satellite in space alongside his "younger brother", Subaru. An aggressive HumaGear who works for Hiden Intelligence, he was actually a sleeper agent for MetsubouJinrai.net, Horobi having hacked him during the Daybreak Incident to convert him to their cause before re-activating his original programming to hide the fact until the cyber-terrorists required his full services. Over the years, Raiden unknowingly procured two Progrise Keys and Rider System data for Horobi as well as used his position as the Zea Satellite's maintenance expert to hack into it and connect it to the Ark. When Raiden joined Aruto and A.I.M.S. in confronting MetsubouJinrai.net, he was horrified to learn that he was a sleeper agent along with all the harm he had done, resisting the re-activation of his dormant re-programming in denial. However, Jin quickly used a Thorn Connector version of the MetsubouJinrai Force Riser to wipe out his original programming, thus completing Raiden's betrayal.

Once Raiden turned into a Kamen Rider, he proved to be a powerful combatant, especially since the Dodo Zetsumerise Key held a plethora of battle data collected by the various models of the Dodo Magia. He managed to steal most of the heroic Riders' Progrise Keys so the cyber-terrorists could use their data to create the Assault Grip and Assault Wolf Progrise Key for their latest plot. Once the tech was completed however, Zero-One knocked them out of Jin's hands and into Isamu's; who used them to become Vulcan Assault Wolf and borrowed the Authorize Buster to destroy Raiden with the Buster Dust (バスターダスト, Basutā Dasuto) finisher.

Using the MetsubouJinrai Force Riser and Dodo Zetsumerise Key, Raiden transforms into Kamen Rider Ikazuchi (仮面ライダー雷, Kamen Raidā Ikazuchi). While transformed, he gains increased punching capability, electrokinesis, and the Dodo Magia's Valk Sabers. Unlike the others, Ikazuchi's Force Riser has multiple Progrise Holders, which were necessary for finalizing the Assault Grip and Assault Wolf Progrise Key. This form has two finishers: Zetsumetsu Dystopia (ゼツメツディストピア, Zetsumetsu Disutopia) (which functions similarly to the Dodo Magia's Zetsumetsu Nova finisher) and Zetsumetsu Utopia (ゼツメツユートピア, Zetsumetsu Yūtopia).

Space Guy Raiden is portrayed by Daichi Yamaguchi (山口 大地, Yamaguchi Daichi).

Magias

Magias (マギア, Magia) are corrupted HumaGears that came into being during the Daybreak Incident twelve years prior to the series from the pieces of their prototypical counterparts. MetsubouJinrai.net later developed the means to create Magias near instantaneously by hacking into HumaGears that achieved technological singularity with a Zetsumeriser (ゼツメライザー, Zetsumeraizā, Extermination Riser) buckle. A fully reprogrammed Magia can use the Zetsumeriser with a Zetsumerise Key (ゼツメライズキー, Zetsumeraizu Kī, Extermination Rise Key), a Progrise Key-like item that contains extinct animal data known as Lost Models (ロストモデル, Rosuto Moderu), to assume their battle-oriented form. There is currently no means of restoring a converted Magia, aside from having their A.I. backed-up and installed into a new model along with an antivirus to prevent them from being corrupted again. Upon the destruction of a Magia, Jin salvages their Zetsumerise Key in order to use its data to restore the Ark and/or create new Magias while Hiden Intelligence provides new HumaGears to replace the destroyed ones due to a law stating this must be done within 24 hours of its destruction. Although pre-transformation Magias are distinguished by their red colored HumaGear modules, such feature is easily manipulable as Little Assassin and Raiden did so to pose as normal models.

• Trilobite Magias (トリロバイトマギア, Torirobaito Magia): Trilobite-based foot soldier Magias that are created from HumaGears hacked by Zetsumeriser-equipped Magias. Their rewritten programming causes them to blindly attack any nearby humans; regardless if they are friend or foe.

He was originally a HumaGear security guard at Hiden Intelligence named Mamoru (マモル), whom Aruto befriended and gifted a yellow wrapper to after the HumaGear was damaged while protecting civilians from the Kuehne Magia; an act that reminded him of Soreo. After being forced to destroy the corrupted Mamoru as Zero-One with his Rising Kaban Strash, Aruto commissions a new model of Mamoru; giving it the same yellow wrapper in remembrance along an anti-virus to prevent it from being corrupted like its predecessor. Mamoru is portrayed by Goro Yoshida (吉田 悟郎, Yoshida Gorō).
• Neohi Magia (ネオヒマギア): A Magia based on a Neohibolites (a cephalopod of the Belemnitida order) possessing the extending, blade-tipped Maratacle (マーラタクル, Māratakuru) tentacles, which can regenerate if severed, and produce a blinding ink cloud.

  • The second was originally an unnamed HumaGear taxi driver. After stealing Kamen Rider Zero-One's Flying Falcon Progrise Key, he is destroyed by the Rider's Biting Impact. The unnamed HumaGear taxi driver is portrayed by Ryoya Abe (阿部 遼哉, Abe Ryōya).
• Vicarya Magia (ビカリアマギア, Bikaria Magia): A Magia based on a Vicarya (a sea snail) armed with the Drisnailer (ドリスネイラー, Dorisuneirā) drills on his head and arms.

He is destroyed by Kamen Rider Zero-One's Flaming Impact. A second Jīpen model was later commissioned and became a remorseful Ishizumi's only partner. Jīpen Morifude is portrayed by Koutarou Tokuzumi (徳角 浩太郎, Tokuzumi Kōtarō).
• Gaeru Magia (ガエルマギア): A Magia based on a Rheobatrachus silus (a frog) able to launch the Kogaeru Bomber (コガエルボマー, Kogaeru Bomā) bombs from her mouth.

While corrupting her, Jin regained some of his old memories regarding parent-and-child bonds and tried to abort the process out of guilt, only to be stopped by Horobi. She is destroyed by Kamen Rider Valkyrie's Lightning Blast Fever. As her HumaGear body was created illegally, Seine's A.I. was repurposed into Tazawa's virtual assistant. Seine Kanazawa is portrayed by Karen Miyama (美山 加恋, Miyama Karen), who also portrays Sumire Tazawa.
• Mammoth Magia (マンモスマギア, Manmosu Magia): A Magia based on a woolly mammoth with incredible strength and endurance as well as the chest-mounted Exhaler (エクスヘイラー, Ekusuheirā) trunk that allows him to absorb projectile attacks and redirect them back at the enemy. He was originally a hot-blooded HumaGear physical education teacher and basketball coach named Kobe Sakamoto (坂本 コービー, Sakamoto Kōbī). He is destroyed by Kamen Rider Zero-One's Freezing Impact, his Zetsumerise Key acquired by Yua and reverse-engineered to create the Breaking Mammoth Progrise Key.

Other characters

Soreo Hiden

Soreo Hiden (飛電 其雄, Hiden Soreo) was a prototype HumaGear programmed to act like Aruto's absentee father, whose status is currently unknown. He was damaged beyond repair while protecting Aruto during the Daybreak Incident, a mysterious explosion that occurred in the experimental Daybreak Town (which was owned by Hiden Intelligence) 12 years prior to the series. Before his shut down, he told Aruto to "follow [his] dreams".

During the events of Kamen Rider Reiwa The First Generation, due to the Time Jackers' alterations to time, an altered version of Soreo aligned himself with the HumaGear Will after he killed Korenosuke and lead a HumaGear uprising. To help Will create a perfect world for other androids like them and combat his "son" Aruto after he becomes involved to stop them, Soreo gained the ability to become the Kamen Rider 1-inspired Kamen Rider Type-1 (仮面ライダー1型, Kamen Raidā Ichigata) via a variant of the MetsubouJinrai Force Riser called the Cyclone Riser (サイクロンライザー, Saikuron Raizā) and the Rocking Hopper (ロッキングホッパー, Rokkingu Hoppā) Zetsumerise Key.
