List of Kamen Rider Zero-One characters

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][5]

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.[6]

After losing the 5-part Workplace Competition to his corporate rival Gai Amatsu, Aruto secretly downloaded all of the HumaGears' personality profiles from the There satellite before they are erased so he can continue the Hiden legacy by creating a new company, Hiden Manufacturing Co., Ltd.[4] 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.[7] After Horobi destroyed Aruto's secretary, Is, however,[8] 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.[9][10] 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.[11]

To transform into Kamen Rider Zero-One, Aruto utilizes the Rising Hopper Progrise Key (ライジングホッパープログライズキー, Raijingu Hoppā Puroguraizu Kī) in the Hiden Zero-One Driver (飛電ゼロワンドライバー, Hiden Zero Wan Doraibā), with assistance from the There (ゼア, Zea) satellite. While transformed, he gains increased jumping and kicking capabilities.[12][2]

After the Ark destroys the Zero-One Driver, Is uses her connection with the There Satellite to create the Hiden Zero-Two Driver (飛電ゼロツードライバー, Hiden Zero Tsū Doraibā) and the Zero-Two Progrise Key for Aruto so he can become Kamen Rider Zero-Two (仮面ライダーゼロツー, Kamen Raidā Zero Tsū).[13] Despite the There Satellite's destruction, its AI was backed up, allowing Aruto to rebuild the Zero-One Driver.[11]

Ever since, he developed a hatred for HumaGears and vowed to destroy them.[3] While investigating the Daybreak Incident however,[27] he slowly grew to care for them.[16][21][5] After ZAIA absorbed Hiden Intelligence, Isamu left A.I.M.S. and joined Aruto's new company, Hiden Manufacturing, as a security guard.[18][4][28][29]

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.[29] While Naki's ally, Jin, eventually figured out a way to separate their A.I. from Isamu,[30][31] he learned that most of his memories were not truly his barring his normal childhood.[27][31] After Horobi's defeat, Isamu becomes an independent Kamen Rider to protect civilians.[10][11]

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.[3]

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

After learning of Gai's machinations, Yua was brainwashed into aiding him before Fuwa eventually helped her work up the courage to quit ZAIA and A.I.M.S. and overcome Gai's mind control.[21][36][25] 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.[30][31][19] Following Horobi's defeat, Yua returns to her old position in A.I.M.S. and conscripts Naki into their ranks.[11]

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.[21] 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),[38] saw no use for such things and made him return it to Hiden Intelligence.[20]

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.[21] When Kamen Rider Zero-One arose to combat MetsubouJinrai.net,[2][21] Gai created the ZAIA ThousanDriver (ザイアサウザンドライバー, Zaia Sauzandoraibā), 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][6][39][40][5][41][42][4]

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 There satellite 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.[20][43][13] As a result however, he is demoted and sent to a new, smaller division of ZAIA.[8] 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.[9][11]

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

The Ark (アーク, Āku) is an experimental satellite that was originally part of the HumaGear project as well as the There Satellite's predecessor. 12 years prior to the series, it 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, resulting in the Ark's A.I. concluding that humanity must be exterminated as their existence will eventually lead to the extinction of all other lifeforms.[21][17] To prevent it from taking control of all of the world's HumaGears, Soreo Hiden stopped the 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.[6][44]

By the present, MetsubouJinrai.net slowly reactivated the Ark until it created an envoy, As, to collect Horobi, Jin, Naki and Ikazuchi's singularity data so it can possess them and manifest in a corporeal form.[19] To ensure its survival, the Ark compromises the There Satellite's systems so it can backup its data and resurrect itself as many times as it needs to should its corporeal form be destroyed in battle.[43][13] After recording data from its battles with Kamen Rider Zero-Two and a traitorous Horobi, the Ark realizes its needs to finalize its singularity by possessing human hosts.[7] To this end, it had As back up its programming and find suitable hosts so it can attain a physical form. While Ikazuchi and Subaru destroyed the There Satellite, the Ark was able to continue manipulating Aruto and Horobi into acting on its will until they purged themselves of its influence.[8][9][10][11]

Initially, the Ark possessed a member of MetsubouJinrai.net and granted them the Ark Driver-Zero (アークドライバーゼロ, Āku Doraibā Zero) so it can transform into Kamen Rider Ark-Zero (仮面ライダーアークゼロ, Kamen Raidā Āku Zero).[19] After losing the There Satellite,[7] the Ark uploaded its data into the Ark-One (アークワン, Āku Wan) Progrise Key so can possess human hosts and grant them the Ark Driver-One (アークドライバーワン, Āku Doraibā Wan) so it can transform into Kamen Rider Ark-One (仮面ライダーアークワン, Kamen Raidā Āku Wan).[8][9]
