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 franchise and the first to air in the Reiwa period.

The cast of Kamen Rider Zero-One was announced on July 17, 2019.^[1]

Aruto Hiden (飛電 或人, Hiden Aruto) is a kind-hearted failed comedian who is appointed the CEO of Hiden Intelligence following the death of his grandfather, Korenosuke, and inherits the power to become Kamen Rider Zero-One. Initially reluctant to take on the role, he accepted it after witnessing MetsubouJinrai.net, and later ZAIA Enterprise, threaten the peace between humans and Humagears.^[2][3]

During the events of Kamen Rider Reiwa: The First Generation, Aruto finds himself in an alternate timeline version of Daybreak Town before being attacked by Another Zero-One, a monster created by the Time Jacker Finis, who came from the World of Zi-O to alter his history; resulting in him temporarily losing his powers. During this time, Aruto's father Soreo secretly gave his son a Force Riser so he could become Kamen Rider Zerozero-One (仮面ライダー001(ゼロゼロワン), Kamen Raidā Zero Zero Wan) to regain his powers.^[4]

After losing the 5-part Workplace Competition to his corporate rival Gai Amatsu, Aruto secretly downloaded all of the Humagears' personality profiles from the Satellite Zea before they are erased so he can continue the Hiden legacy by creating a new company, *Hiden Manufacturing Co., Ltd. (飛電製作所, Hiden Seisakujo Kabushiki Gaisha)^[5] in order to maintain his family legacy of distributing Humagears. When the malevolent A.I. Ark arises to destroy humanity, Gai joins forces with Aruto to defeat it; making amends with him by relinquishing control of Hiden Intelligence and returning the company to him along the way.^[6] After Horobi destroyed Aruto's secretary, Is, however,^[7] the Ark's emissary As gives Aruto the Ark-One Progrise Key, turning him into the Ark's first human host and giving him the power to transform into Kamen Rider Ark-One to seek revenge while retaining partial control over himself.^[8][9] While fighting Horobi however, Soreo reminded him of why he became a Kamen Rider, which gave Aruto the resolve to purge himself and Horobi of the Ark's influence before letting him destroy the Ark-One system; reconciling their differences in the process.^[10]

To transform into Kamen Rider Zero-One, Aruto utilizes the Rising Hopper (ライジングホッパー, Raijingu Hoppā) Progrise Key (プログライズキー, Puroguraizu Kī) SD card in the Hiden Zero-One Driver (飛電ゼロワンドライバー, Hiden Zero Wan Doraibā) belt, with assistance from the Satellite Zea. While transformed, he gains increased jumping and kicking capabilities. He also wields the Attache Calibur (アタッシュカリバー, Atasshu Karibā), which can change from its briefcase-like Attache Mode (アタッシュモード, Atasshu Mōdo) to its sword-like Blade Mode (ブレードモード, Burēdo Mōdo).^[11][2] His personal motorcycle is the Rise Hopper (ライズホッパー, Raizu Hoppā), which he can summon from the Satellite Zea by scanning the Hiden Risephone (飛電ライズフォン, Hiden Raizufon) on the Hiden Zero-One Driver. Over the course of the series, Aruto gains other Progrise Keys that grant new forms for different combat situations:

• Biting Shark (バイティングシャーク, Baitingu Shāku): An auxiliary form that grants increased swimming and cutting capabilities.^[12]
• Flying Falcon (フライングファルコン, Furaingu Farukon): An auxiliary form that grants flight capabilities.^[11][13] This form first appears in the film Kamen Rider Zi-O the Movie: Over Quartzer.
• Flaming Tiger (フレイミングタイガー, Fureimingu Taigā): An auxiliary form that grants pyrokinesis.^[14]
• Freezing Bear (フリージングベアー, Furījingu Beā): An auxiliary form that grants cryokinesis.^[15]
• Breaking Mammoth (ブレイキングマンモス, Bureikingu Manmosu): A mecha-like form created from the Satellite Zea that grants increased strength as well as flight capabilities via an alternate Jet Form (ジェットフォーム, Jetto Fōmu).^[16]
• Shining Hopper (シャイニングホッパー, Shainingu Hoppā): An upgraded version of Aruto's Rising Hopper form that grants super-speed, the ability to instantaneously calculate multiple possible outcomes, and create 3D illusions.^[17][18]
  • Shining Assault Hopper (シャイニングアサルトホッパー, Shainingu Asaruto Hoppā): A fusion form accessed from the Shining Hopper Progrise Key combined with the Assault Grip that grants increased offensive and defensive capabilities as well as the use of the Shine Cryster (シャインクリスタ, Shain Kurisuta) energy drones. In this form, Aruto wields the Authorise Buster (オーソライズバスター, Ōsoraizu Basutā), which can switch between Gun Mode (ガンモード, Gan Mōdo) and Axe Mode (アックスモード, Akkusu Mōdo).^[19]
• Metal Cluster Hopper (メタルクラスタホッパー, Metaru Kurasuta Hoppā): Aruto's super form that grants nanorobotic Hiden Metal (飛電メタル, Hiden Metaru) armor capable of molding itself into various shapes and forms.^[20][21] In this form, Aruto wields the Progrise Hopper Blade (プログライズホッパーブレード, Puroguraizu Hoppā Burēdo) sword, which can change from Blade Mode to Naginata Mode (ナギナタモード, Naginata Mōdo) by combining with the Attache Calibur.^[22]
• Realizing Hopper (リアライジングホッパー, Riaraijingu Hoppā): An enhanced version of Aruto's Rising Hopper form.^[10]
• Hell Rising Hopper (ヘルライジングホッパー, Heruraijingu Hoppā): A unique form accessed from the Hell Rise (ヘルライズ, Heru Raizu) Progrise Key. This form appears exclusively in Kamen Rider Zero-One the Movie: Real×Time.

Using the Hiden Zero-Two Driver (飛電ゼロツードライバー, Hiden Zero Tsū Doraibā) belt and the Zero-Two (ゼロツー, Zero Tsū) Progrise Key, Aruto can transform into Kamen Rider Zero-Two (仮面ライダーゼロツー, Kamen Raidā Zero Tsū).^[23]

Aruto Hiden is portrayed by Fumiya Takahashi (高橋 文哉, Takahashi Fumiya).^[1] As a child, Aruto is portrayed by Haruto Nakano (中野 遥斗, Nakano Haruto).

Is (イズ, Izu) is a Humagear secretary programmed to be loyal to Hiden Intelligence's CEO.^[2] In reality, her loyalties lie with the Hiden family while her programming binds her to Kamen Rider Zero-One's technology.^[5] Unlike other Humagears, Is was built without a means to back herself up as a security measure to prevent information on the Zero-One technology from falling into enemy hands.^[18] After ZAIA gained control of Hiden Intelligence and Aruto almost sacrificed himself to protect her, she achieved technological singularity,^[5] but is later destroyed by Horobi, much to Aruto's grief.^[7] As her data cannot be restored, Aruto instead creates a second Is, hoping that he can teach her to think and feel for herself like he did with the original one.^[10]

During the events of Kamen Rider Zero-One the Movie: Real×Time, the rebuilt Is gains the memories of her original self through the Satellite ZEA and is entrusted with the Zero-Two Driver, which she uses to transform into Kamen Rider Zero-Two and join Aruto in his fight against Es and his forces.^[24]

Is is portrayed by Noa Tsurushima (鶴嶋 乃愛, Tsurushima Noa).^[1]

The Artificial Intelligence Military Service (対人工知能特務機関, Tai Jinkō Chinō Tokumu Kikan), or A.I.M.S. (エイムズ, Eimuzu), is a government established and ZAIA Enterprise funded organization dedicated to destroying rogue Humagears, or Magias, hacked by MetsubouJinrai.net as Humagear-related crimes fall within their jurisdiction.^{[2][25][12][26]}

To transform, A.I.M.S.'s Kamen Riders use Progrise Keys and the A.I.M.S. Shot Riser (エイムズショットライザー, Eimuzu Shotto Raizā) belt, which can also be used as a gun whether they are transformed or not.^[2][25] In order to use the Shot Risers, the Riders are implanted with cranial A.I. chips, though this also makes them vulnerable to mental manipulation.^[27][28] They also wield the Attache Shotgun (アタッシュショットガン, Atasshu Shottogan), which can change from Attache Mode to its rifle-like Shotgun Mode (ショットガンモード, Shottogan Mōdo).^[14]

After ZAIA bought out Hiden Intelligence, A.I.M.S. troopers are given Raid Risers and Invading Horseshoe Crab Progrise Keys to become Battle Raiders as well as ZAIA's personal foot soldiers.^[5] Following this, A.I.M.S.' Riders eventually quit the organization and underwent surgery to remove the A.I. chips' mind control programs while retaining their ability to use the Shot Riser.^[28][29] Despite this, they and the Raiders are still vulnerable to the Ark's influence.^[30][31]

Due to Kamen Rider MetsubouJinrai destroying ZAIA's Japanese branch during the events of the V-Cinema Zero-One Others, A.I.M.S. lost the blueprints to repair their transformation devices.^[32][33]

Isamu Fuwa (不破 諫, Fuwa Isamu) is an A.I.M.S. captain and a survivor of the Daybreak Incident, which claimed his classmates' lives. Ever since, he developed a hatred for Humagears and vowed to destroy them.^[25] While investigating the Daybreak Incident however,^[13] he slowly grew to care for them.^[16][34][3] After ZAIA absorbed Hiden Intelligence, Isamu left A.I.M.S. and joined Aruto's new company, Hiden Manufacturing, as a security guard.^{[28][5][35][36]}

As part of ZAIA CEO Gai's machinations, Isamu's A.I. chip was replaced with that of MetsubouJinrai.net member, Naki, which also gave him false memories.^[36] While Naki's ally, Jin, eventually figured out a way to separate their A.I. from Isamu,^[37][38] he learned that most of his memories were not truly his barring his normal childhood.^[13][38] After Horobi's defeat, Isamu becomes an independent Kamen Rider to protect civilians.^[9][10]

During the events of the V-Cinemas Zero-One Others, Isamu establishes his own shell corporation under Aruto's advice as a means of accessing the Hiden Zero-One Driver, using it alongside Sold 09's Zetsumerise Key to stop the rampaging Kamen Rider MetsubouJinrai after Yua is incapacitated and his Shot Riser is damaged beyond repair. However, he is critically wounded following the battle with his survival unconfirmed.^[33]

Utilizing the Shooting Wolf (シューティングウルフ, Shūtingu Urufu) Progrise Key in the Shot Riser, Isamu can transform into Kamen Rider Vulcan (仮面ライダーバルカン, Kamen Raidā Barukan) and gain increased shooting accuracy.^[25] Over the course of the series, Isamu gains other Progrise Keys that grant new forms for different combat situations:

• Punching Kong (パンチングコング, Panchingu Kongu): An auxiliary form that grants increased punching capabilities.^[13]
• Assault Wolf (アサルトウルフ, Asaruto Urufu): An upgraded version of Isamu's Shooting Wolf form accessed from the Assault Wolf Progrise Key combined with the Assault Grip (アサルトグリップ, Asaruto Gurippu) device that grants the ability to fire energy bullets and projectiles.^[39]
• Rampage Vulcan (ランペイジバルカン, Ranpeiji Barukan): Isamu's super form accessed from the Rampage Gatling (ランペイジガトリング, Ranpeiji Gatoringu) Progrise Key that grants combined usage of the Shooting Wolf, Punching Kong, Rushing Cheetah, Lightning Hornet, Biting Shark, Flying Falcon, Flaming Tiger, Freezing Bear, Breaking Mammoth, and Sting Scorpion Progrise Keys' abilities.^[28]
• Orthoros Vulcan (オルトロスバルカン, Orutorosu Barukan): A unique form accessed from Naki's Japanese Wolf Zetsumerise Key that Isamu attained after the Ark negated his ability to transform normally that grants aerokinesis and increased slashing capabilities.^[9]
• Lone Wolf (ローンウルフ, Rōn Urufu): A special last resort form accessed from the Dire Wolf (ダイアウルフ, Daia Urufu) Zetsumerise Key combined with the Assault Grip that is used in the Hiden Zero-One Driver. This form appears exclusively in Zero-One Others: Kamen Rider Vulcan & Valkyrie.^[33]

Isamu Fuwa is portrayed by Ryutaro Okada (岡田 龍太郎, Okada Ryūtarō).^[1] As a child, Isamu is portrayed by Soshi Hagiwara (萩原 壮志, Hagiwara Sōshi).

Yua Yaiba (刃 唯阿, Yaiba Yua) is A.I.M.S.'s technical advisor and maintenance expert who developed A.I.M.S.'s Rider system and handles Progrise Key authorization, being Isamu's commanding officer in the field despite her partner's rank.^[2][25] In reality, she secretly works for ZAIA and Gai, who recommended her to A.I.M.S. to oversee their equipment,^{[12][26][15][40][41]} though she was able to work behind their back to help Isamu and Aruto.^[18][39]

After learning of Gai's machinations, Yua was forced to aid him against her will before Isamu eventually helped her work up the courage to quit ZAIA and A.I.M.S. and overcome Gai's mind control.^[34][42][29] Afterwards, Yua remains in touch with Hiden Manufacturing and Jin to keep an eye on ZAIA and MetsubouJinrai.net’s plans until the Ark's ascension.^[37][38][30] Following Horobi's defeat, Yua returns to her old position in A.I.M.S. and conscripts Naki into their ranks.^[10]

Utilizing the Rushing Cheetah (ラッシングチーター, Rasshingu Chītā) Progrise Key in the Shot Riser, Yua can transform into Kamen Rider Valkyrie (仮面ライダーバルキリー, Kamen Raidā Barukirī) and gain increased speed.^[12] Over the course of the series, Yua gained other Progrise or Zetsumerise Keys that grant new forms for different combat situations.

• Lightning Hornet (ライトニングホーネット, Raitoningu Hōnetto): An auxiliary form that grants flight capabilities and the use of micro missiles.^[26]
• Justice Serval (ジャスティスサーバル, Jasutisu Sābaru): Yua's super form accessed from the Serval Tiger (サーヴルタイガー, Sābaru Taigā) Zetsumerise Key that grants a pair of claws. This form appears exclusively in Zero-One Others: Kamen Rider Vulcan & Valkyrie.^[33]

While aiding Gai's conspiracy, she temporarily used a Raid Riser and the Fighting Jackal Progrise Key to become the Fighting Jackal Raider.^{[42][28][5][35][36][29]}

Yua Yaiba is portrayed by Hiroe Igeta (井桁 弘恵, Igeta Hiroe).^[1]

Gai Amatsu (天津 垓, Amatsu Gai) is ZAIA Enterprise Japan's CEO and the mastermind behind the series' events.^[34] While growing up, Gai used to love artificial beings, such as his robot dog, Thouser (さうざー, Sauzā). However, his strict and demanding father, Ikkei Amatsu (天津 一京, Amatsu Ikkei),^[43] saw no use for such things and made him return it to Hiden Intelligence.^[44]

Years later, Gai eventually joined ZAIA and became Korenosuke Hiden's partner and protégé. However, he disagreed with the latter's belief that Humagears were the future as he believed humanity should evolve through technology. After falling out with Korenosuke, Gai uploaded data on humanity's negative traits to the Ark and created an A.I. that vowed to exterminate humanity and created MetsubouJinrai.net to further his ambitions.^[34] When Kamen Rider Zero-One arose to combat MetsubouJinrai.net,^[2][34] Gai created the ZAIA ThousanDriver (ザイアサウザンドライバー, Zaia Sauzandoraibā) belt, the Amazing Caucasus (アメイジングコーカサス, Ameijingu Kōkasasu) Progrise Key, and the Awaking Arsino (アウェイキングアルシノ, Aweikingu Arushino) Zetsumerise Key so he can become Kamen Rider Thouser (仮面ライダーサウザー, Kamen Raidā Sauzā) and challenge Aruto for technological supremacy.^{[16][4][45][46][3][20][22][5]}

After the Ark's ascension and MetsubouJinrai.net's resurgence, Aruto and his allies eventually learn Gai's history and why he wanted the Hiden family's assets. In response, the Satellite Zea created a new dog for Gai, inspiring him to atone for his actions by helping them defeat the Ark and giving Hiden Intelligence back to Aruto.^[44][47][23] As a result, however, he is demoted and sent to a new, smaller division of ZAIA.^[7] After Horobi's defeat, Gai rebuilds the ThousanDriver after losing the original to the Ark and bought another four of Hiden Intelligence's robot dogs to be his companions.^[8][10]

In the web-exclusive series Kamen Rider Genms: The Presidents, Gai founds the company Thouser-Intellion (サウザンインテリオン, Sauzan Interion) alongside his Humagear secretary Rin after the dissolution of ZAIA Enterprise Japan to start anew without ZAIA. However, he becomes infected with Kuroto Dan's strain of the Bugster Virus, causing him to transform into a black-colored version of Thouser.^[48] Despite this, Gai overcomes the infection by resolving to become a good president for his company and getting Kuroto and Masamune Dan to reconcile in the middle of their fight.^[49]

In the web-exclusive series Kamen Rider Genms: Smart Brain and the 1000% Crisis, the Ark manipulates Gai into becoming Kamen Rider Thousand Ark.^[50]

Gai Amatsu is portrayed by Nachi Sakuragi (桜木 那智, Sakuragi Nachi). As a child, Gai is portrayed by Seiru (星流).

MetsubouJinrai.net (滅亡迅雷.net, Metsubōjinrai Netto, DestructiveThunderclap.net) is a cyber-terrorist organization based in the condemned Daybreak Town (デイブレイクタウン, Deibureiku Taun).^[2] Lead by the rogue prototype Humagears, Horobi and Jin, they seek to either wipe out humanity by restoring the Satellite Ark or liberate Humagears from humanity.^{[51][39][52][27]} Initially, MetsubouJinrai.net reBehrued against Hiden Intelligence, believing they were responsible for enslaving Humagears following the Daybreak Incident.^{[25][13][16][19]} However, after they learned that ZAIA had been using them,^[53] the cyber-terrorists aimed to fight them as well while keep Hiden Manufacturing from interfering.^[52][37][38] After the Ark's manifestation as Kamen Rider Ark-Zero, MetsubouJinrai.net initially adjusted their plans towards enslaving humanity until Aruto helped them achieve a unique form of singularity, leading to the cyber-terrorists defecting from the Ark.^{[54][30][31][47][23][6]} After Horobi is purged of the Ark's influence, the remaining members reorganized their goals to watch over mankind and prevent the emergence of a new Ark.^[10] However, amidst their conflict with Lyon Arkland, the remaining four members were fused into and suppressed by Kamen Rider MetsubouJinrai.^[32] Despite this, they are able to secretly manipulate MetsubouJinrai into attacking Fuwa, who destroys it.^[33]

Most members of MetsubouJinrai.net use the MetsubouJinrai Force Riser (滅亡迅雷フォースライザー, Metsubōjinrai Fōsu Raizā) belt in conjunction with Progrise or Zetsumerise Keys to transform. They also wield the Attache Arrow (アタッシュアロー, Atasshu Arō), which can change from Attache Mode to its bladed bow-like Arrow Mode (アローモード, Arō Mōdo).^{[13][26][51][39][31]} As depicted in Kamen Rider Reiwa: The First Generation, the Force Risers are potentially fatal to humans.^[4]

Horobi (滅) is MetsubouJinrai.net's leader and Jin's Humagear "father" who has the power to become Kamen Rider Horobi (仮面ライダー滅, Kamen Raidā Horobi) by utilizing the Sting Scorpion (スティングスコーピオン, Sutingu Sukōpion) Progrise Key in the Force Riser.^[2][13][51] He is the "son" of the prototype Humagear Hakase Bot (博士ボット, Hakase Botto, Doctor Bot), who originally developed him to be an educational parent-type Humagear before the Ark corrupted him sometime after ZAIA sabotaged the abandoned satellite's systems.^[52][38] Aruto tries to save him and help realize he had been manipulated his entire life, leading Horobi to seemingly defect from the Ark.^[6] With the Ark secretly manipulating him however, he staged a Humagear rebellion before he temporarily lost Jin and accepted the Ark's power once more.^[7][8][9] After coming to terms with his mistakes, purging himself of the Ark's influence, and reconciling with Aruto, Horobi reorganized MetsubouJinrai.net so the organization will watch over mankind and prevent the creation of another Ark.^[10]

To counter Aruto after he becomes Kamen Rider Ark-One, Horobi obtains a modified Zero-One Driver called the Zetsumetsu Driver (絶滅ドライバー, Zetsumetsu Doraibā)^[a] and the Ark-Scorpion (アークスコーピオン, Āku Sukōpion) Progrise Key to transform into Kamen Rider Horobi Ark-Scorpion (仮面ライダー滅アークスコーピオン, Kamen Raidā Horobi Āku Sukōpion).^[9]

Horobi is portrayed by Syuya Sunagawa (砂川 脩弥, Sunagawa Shūya).^[1]

Jin (迅) is Horobi's Humagear "son" and a hacker who specializes in spreading the rewriting program that turns Humagears into Magias who can transform into Kamen Rider Jin (仮面ライダー迅, Kamen Raidā Jin).^{[2][26][52][27]} Initially immature and erratic, Jin faithfully served Horobi and MetsubouJinrai.net in their plots until Aruto destroyed him in battle.^[34] After Williamson Yotagaki rebuilt him as Sold 0 (ソルド0, Sorudo Zero), Jin became more serious-minded and developed a tendency to clash with Horobi over their respective beliefs for Humagear welfare.^{[52][27][57][32]} Following the Ark's ascension as Kamen Rider Ark-Zero and learning of its true nature,^[54][30] Jin worked with Yua to stop it and left MetsubouJinrai.net.^[31][23] He was briefly destroyed once more by Ark-One in an attempt to protect Horobi and save Aruto from the Ark's influence, but was rebuilt by Yua via an earpiece provided by Williamson.^[10]

Initially, Jin stole Aruto's Flying Falcon Progrise Key and used it in the Force Riser to transform into Kamen Rider Jin.^[26] After Yotagaki rebuilt him, he uses the Burning Falcon (バーニングファルコン, Bāningu Farukon) Progrise Key in the ZAIA Slash Riser (ザイアスラッシュライザー, Zaia Surasshu Raizā) belt, the latter of which can also be used as a dagger.^[52]

Jin is portrayed by Daisuke Nakagawa (中川 大輔, Nakagawa Daisuke).^[1]

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 (ヒューマギアモジュール, Hyūmagia Mojūru) worn around their ears as well as a Humagear Body Seal authorization device on their bodies being the only signs of their status as a Humagear.^[2][25] During the events of the V-Cinema Zero-One Others: Kamen Rider MetsubouJinrai, the company launched the Satellite We're (衛星ウィア, Eisei Wia) following the destruction of the Satellite Zea (衛星ゼア, Eisei Zea).^[58][32]

Jun Fukuzoe (福添 准, Fukuzoe Jun) is the Vice President of Hiden Intelligence who had coveted the CEO position after Korenosuke's death. While he initially wanted Aruto removed,^[2][25][16] he eventually came to respect him.^[19] After Hiden Intelligence was absorbed by ZAIA Enterprise, Fukuzoe continued working with the former on behalf of the Hiden name despite the situation.^[28][5] After learning of Gai's crimes, he left to rejoin Aruto at Hiden Manufacturing and work with the police to expose ZAIA's crimes.^[30][44]

Jun Fukuzoe is portrayed by Kazuya Kojima (児嶋 一哉, Kojima Kazuya).^[1]

Shesta (シェスタ, Shesuta) is a Humagear secretary programmed to be loyal to Hiden Intelligence's Vice President.^[2] After ZAIA bought out Hiden Intelligence, Shesta began working for Hiden Manufacturing.^[5]

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

Sanzō Yamashita (山下 三造, Yamashita Sanzō) is the Senior Managing Director of Hiden Intelligence who serves as Fukuzoe's underling.^[2] After Hiden Intelligence was absorbed by ZAIA, Yamashita continued working with the former on behalf of the Hiden name despite the situation.^[28][5] After learning of Gai's plans, he left to rejoin Aruto at Hiden Manufacturing.^[30]

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

Korenosuke Hiden (飛電 是之助, Hiden Korenosuke) was Aruto's grandfather and the original CEO of Hiden Intelligence.^[2] Aware of ZAIA Enterprise's machinations following the Daybreak Incident,^[34] Korenosuke patented all of Kamen Rider Zero-One's technology under the Hiden family name instead of Hiden Intelligence's CEO.^[5]

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

Hiden Soreo (飛電 其雄) was a parent-type older generation Humagear programmed to act like Aruto's similarly named deceased father, Soreo Hiden (飛電 其雄, Hiden Soreo), to emotionally support Aruto during his childhood before the Humagear was damaged beyond repair while protecting Aruto during the Daybreak Incident.^[2] According to Ikazuchi’s database, Soreo's data pattern was used as a base to build Horobi prior to Gai corrupting the Ark.^[37] Despite this, Soreo's A.I. remained active and was able to reach out to his "son" while the latter was possessed by the Ark.^[10]

During the events of Kamen Rider Reiwa: The First Generation, Soreo’s original fate was altered by the Time Jacker Finis. As a result, he gained the ability to become Kamen Rider Ichi-Gata (仮面ライダー1型, Kamen Raidā Ichigata, lit. "Kamen Rider Type-One") by utilizing the Rocking Hopper (ロッキングホッパー, Rokkingu Hoppā) Zetsumerise Key in the Cyclone Riser (サイクロンライザー, Saikuron Raizā) belt; both of which he designed before the Zero-One Driver. After the Humagear Will killed Korenosuke and took over the world, Soreo feigned allegiance to him while secretly carrying on Korenosuke's Zero-One project to ensure its completion. He also secretly gave Aruto a Force Riser so he could regain his powers. Soreo eventually revealed his true agenda, but the Ark brainwashed him and forced him to fight Aruto, though this was also part of Soreo's plan as he had to be defeated by Aruto's hand. Once the timeline was restored, Soreo's fate was changed back.^[4]

Hiden Soreo is portrayed by Koji Yamamoto (山本 耕史, Yamamoto Kōji).

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. ZAIA was originally partners with Hiden Intelligence until a falling out between the company heads lead to Gai enacting the Daybreak Incident; putting the series' events in motion.^[34] To further their plot, ZAIA produced a glasses-like device called the ZAIA Spec (ザイアスペック, Zaia Supekku), which allows humans to perform at the same level as Humagears while making them more susceptible to the Ark's control,^[3][37] as well as the Raiders' Raid Risers.^[59][42][28]

After Kamen Rider MetsubouJinrai destroys ZAIA's Japanese branch, the company loses the blueprints to their transformation devices, such as A.I.M.S.'s Shot Risers and Jin's Slash Riser.^[32][33]

Williamson Yotagaki (与多垣 ウィリアムソン, Yotagaki Wiriamuson) is an executive of ZAIA Enterprise USA HQ's development department who assumes control of ZAIA Enterprise Japan following Gai's dismissal.^[7] He is also Jin's secret benefactor and associate; providing him with a new body, the ZAIA Slash Riser, and the Burning Falcon Progrise Key following his first defeat.^[52]

Williamson Yotagaki is portrayed by Tomomi Maruyama (丸山 智己, Maruyama Tomomi).

"Ark" (アーク, Āku) is an artificial intelligence originally meant for the Satellite Ark (衛星アーク, Eisei Āku), an experimental satellite named after Lyon Arkland that was originally part of the Humagear project before it was replaced by the Zea Satellite following the Daybreak Incident. 12 years prior to the series, Ark was created by scientists from 11 of Japan's leading tech companies, including Hiden Intelligence and ZAIA Enterprise Japan. However, ZAIA CEO Gai Amatsu fed the Ark with data on human malice, causing Ark to conclude that humanity must be exterminated to prevent the eventual extinction of all other lifeforms.^[34][19] To prevent it from taking control of the world's Humagears, Hiden Soreo stopped the Satellite Ark's launch, causing it to explode and sink into the ruins of Daybreak Town. However, its A.I. remained active and plotted its revival.^[4][52]

Over the years leading up to the present, Ark manipulates Gai and MetsubouJinrai.net into reactivating it while making its presence known through Ark Magias and temporarily possessing Aruto through the Metal Cluster Hopper Progrise Key.^[20] Ark later creates an envoy, As, to collect the MetsubouJinrai.net members' singularity data so it can possess them and gain a corporeal form.^[30] To ensure its survival, Ark compromises the Satellite Zea's systems so it can back up its data and resurrect itself as many times as it needs to should its aforementioned corporeal form be destroyed in battle.^[47][23] After recording data from its battles with Kamen Rider Zero-Two and a traitorous Horobi, Ark realizes it needs to finalize its singularity by possessing human hosts.^[6] To this end, it has As back up its core programming and find suitable hosts, only for Ikazuchi and Subaru to destroy the Zea Satellite and Ark. As attempts to recreate the entity through Aruto and Horobi, but they eventually purge themselves of its influence.^{[7][8][9][10]}

During the events of the web-exclusive crossover series Kamen Rider Genms, Ark selects Kuroto Dan as its new host and manipulates Gai into giving Thouser-Intellion to Kuroto, despite facing interference from Masamune Dan.^[48][49][50]

Initially, Ark possesses a member of MetsubouJinrai.net and grants them the Ark Driver (アークドライバー, Āku Doraibā) belt so it can transform into Kamen Rider Ark-Zero (仮面ライダーアークゼロ, Kamen Raidā Āku Zero).^[30]

After losing the Satellite Zea,^[6] the Ark uploaded its data into a unique Progrise Key capable of summoning the Ark Driver so its human hosts can use them in conjunction with each other to transform into black and white-colored corrupted versions of their original Kamen Rider forms:
