This article is about a/an Rider in Kamen Rider Zero-One.
"Subaru, just because he's the president, doesn't mean you can go easy on him."
―Uchuyaro Raiden voicing his opinion for Aruto Hiden[src]

Uchuyaro Raiden (宇宙野郎雷電 Uchūyarō Raiden, lit. Spaceman Raiden), or simply Raiden, was an Astronaut-Type HumaGear who is in charge of Zea, and the "older brother" of Uchuyaro Subaru who is also an Astronaut-Type Humagear. In secret, he is actually a sleeper agent working for, and possessed the ability to transform into Kamen Rider Ikazuchi (仮面ライダー雷[イカヅチ] Kamen Raidā Ikazuchi, lit. "Masked Rider Thunder").



Uchuyaro Raiden was created to maintain the Ark once it had launched. However, the Daybreak Town Accident prevented the launch from occurring. During the course of the Accident, Raiden's programming was compromised by, who installed new protocols that were undetectable by Raiden himself so that he could serve as a sleeper agent. Hiden Intelligence then shut Raiden down due to him no longer having a task to fulfill. When Zea was successfully launched, Raiden was reactivated and assigned to the satellite to maintain it. However, he unknowingly began leaking Zea's data to

Becoming Ikazuchi

After Aruto summoned the RiseHopper while he and Subaru were in the process of returning it to Zea, Raiden returned to Earth and stormed into Aruto's office. He confronted the young CEO and suggested that he should resign. Aruto apologized and exclaimed that he didn't know. Subaru was satisfied with this answer and began to leave, but Raiden stopped him and continued to berate Aruto and Jun Fukuzoe. Raiden then brought Aruto to the Hiden Space Development Center to give him an appreciation for the hard work that he and his brother do.

Raiden, Subaru, Izu, and Aruto were intercepted by Isamu Fuwa and Yua Yaiba, who asked if Zea was able to detect HumaGears who are approaching singularity. Raiden responded that it can, and Fuwa accused him of being a spy for due to the kanji for his name being present in the organization's name as well. Raiden responded aggressively, and the two almost had a physical confrontation before being separated by Izu and Yaiba. Subaru began to defend his brother, but the group was interrupted by the arrival of Jin, who stated that he had come to take their Progrisekeys and transformed. Aruto, Fuwa, and Yaiba transformed to fight him and the Trilobite Magia that he had created.

Zero-One was able to defeat Jin in Shining Hopper, causing him to attempt to hack Raiden and Subaru using tendrils. Raiden pushed Subaru out of the way to protect him and was pierced by both tendrils. However, he resisted the hacking and removed the tendrils form his body, leading Jin to retreat while commenting that it was no wonder how Raiden survived the Daybreak Town Accident.

Inside the Space Development Center's observatory, Raiden and Subaru related Raiden's history to the group. Raiden stated that he is training Subaru to replace him. Fuwa still suspected Raiden of being a spy, so the HumaGear declared his intention to locate's base to prove his innocence.

Once Raiden and Subaru discovered that was based in Daybreak Town, Raiden brought Aruto and Fuwa there with him to investigate. In a tunnel leading to the lake where the Ark rests, the group is confronted again by Jin, who referred to Raiden as "Ikazuchi". In response, Raiden's MetsuboJinrai programming began to resurface. This lead Fuwa to conclude that he is a spy, though Raiden continued to insist that he wasn't while resisting the programming. Jin explained that Raiden didn't know he was a spy and reveals that MetsubouJinrai had programmed him to transmit Zea's data to them. He also reveals that when he attempted to hack Raiden, he had installed a program that directed him to bring Aruto and Fuwa to their hideout. Jin then attaches a Forceriser to Raiden, forcing him to submit to his dormant programming. Now loyal to, Raiden uses the Forceriser and the Dodo Zetumerise Key provided by Jin to transform into Kamen Rider Ikazuchi.

Aruto and Fuwa transformed to fight Ikazuchi, but he quickly defeated them and took the Biting Shark, Flaming Tiger, Freezing Bear, Breaking Mammoth, Shooting Wolf, and Punching Kong Progrisekeys. Jin then gave him the Sting Scorpion and Flying Falcon Progrisekeys, and he inserted all eight into his Progrise Holders. This resulted in the Progrisekeys' Rider Models being extracted from Zea and entering the Ark, reactivating it. The Ark then created the Assault Wolf Progrisekey.

Aruto transformed into Zero-One Shining Hopper to fight Ikazuchi, and was initially successful in overpowering him. However, the fatigue resulting from using Shining Hopper overwhelmed Aruto and Ikazuchi gained the upper hand. Izu then arrived and supplied Zero-One with the Authorise Buster, which he used to fire a powerful blast at Ikazuchi and cause him to drop the stolen Progrisekeys. Jin recovered the Sting Scorpion and Flying Falcon Progrisekeys, while Izu recovered the rest. Horobi then arrived and gave the Assault Wolf Progrisekey to Jin, but Zero-One fired the Authorise Buster again, resulting in Jin dropping the Progrisekey while avoiding the blast and Aruto being forced out of transformation due to the strain. Fuwa then took the Assault Wolf Progrisekey and transformed into Vulcan Assault Wolf. Ikazuchi attacked Vulcan but to no effect. Vulcan then quickly overwhelmed Ikazuchi and was given the Authorise Buster by Aruto. He used it to fire a construct of Punching Kong's Gauntlet at Ikazuchi, who countered with lightning produced by both hands. However, Vulcan's attack prevailed and destroyed Raiden.

Raiden is later seen in a flashback along with Horobi, Naki, and Jin. I'll Save The HumaGears


Raiden is a HumaGear with an aggressive and passionate personality. He does show immense care for his current model brother Subaru, even willing to risk his life to shield Subaru from Jin's hacking ability. His programming had been compromised by during the Daybreak Town Accident, but continued to function normally as a sleeper agent. When was ready to enact their plan to construct the Assault Wolf Progrisekey, Jin reactivated his corrupted programming. Despite initially being able to resist, the use of a Forceriser bested him. Thus, he became loyal to, though his hotblooded nature remained when fighting as Kamen Rider Ikazuchi.

Rider Statistics[1]

  • Rider Height: 188.5 cm
  • Rider Weight: 99.4 kg

Ability Parameters[1]

  • Punching Power: 17.2 t
  • Kicking Power: 58.6 t
  • Maximum Jump Height: 25.1 m
  • Maximum Running Speed: 100 m per 3.7 seconds

Raiden transforms into Kamen Rider Ikazuchi by using the Dodo Magia Zetsumerisekey in the MetsubouJinrai Forceriser.

Ikazuchi's statistics are the higher than Horobi and Jin's base forms, and are almost equivalent to Zero-One Shining Hopper and Vulcan Assault Wolf except the jumping height. However, due to Assault Wolf's tremendous power granted by the Ark's energy, Ikazuchi was not able to survive for long against him.

Due to Raiden's position as supervisor of Zea, Ikazuchi has the unique ability to control communications devices, including Zea itself. It was because of this ability that he was used by to reactivate the Ark and create the Assault Wolf Progrisekey. Ikazuchi's eight Progrise Holders are modified to allow him to extract the inserted Progrisekeys' Rider Models from Zea through an imitation of the authorization process and direct them into the Ark.

In battle, Ikazuchi is armed with the Dodo Magia's Valk Sabers and can produce lightning from his hands to electrocute his enemies.

Kamen Rider Ikazuchi's suit consists of the following parts:

  • Dodo Head (ドードーヘッド Dōdō Heddo): Ikazuchi's helmet.
    • Dodo Goggles (ドードーゴーグル Dōdō Gōguru): Ikazuchi's facial armor. It is equipped with visual devices, hearing devices, and advanced communication devices that enhance communication management capabilities.
    • Discharge Feather (ディスチャージフェザー Disuchāji Fezā): The Dodo Goggles' lightning emission device. It is able to make connections to external equipment by emitting lightning which can also be diverted for attacks.
    • Dodo Signal (ドードーシグナル Dōdō Shigunaru): The Dodo Goggles' communication control device. It is able to hack and freely operate large-scale communication facilities such as artificial satellites.
    • Dodo Scope (ドードースコープ Dōdō Sukōpu): Ikazuchi's visual equipment. It has excellent resistance to electromagnetic waves, ensuring a clear view at all times. In addition, it has high resistance against burning caused by strong light.
    • Dodo Beak (ドードービーク Dōdō Bīku): The beak-like protrusions on the forehead and chin of the helmet. In addition to improving the force of strikes with the head, it also protects the Dodo Signal.
    • Hearing Back (ヒアリングバック Hiaringu Bakku): Ikazuchi's hearing device. Hearing information is communicated to the wearer through the Restraint Cables.
  • Lazarotech Suit (ラザロテックスーツ Razarotekku Sūtsu): Ikazuchi's base suit. It protects the user from corrosive liquids with a special fabric called Texta Wall (テキスタウォール Tekisuta Wōru) that has extremely low breathability and permeability. It also keeps the internal pressure higher than the external pressure by being airtight. In addition, its materials have high insulation and it has the role of preventing malfunction of internal equipment due to the lightning strikes that Ikazuchi produces.
  • Force Arm (フォースアーム Fōsu Āmu): Ikazuchi's arms. By receiving the energy generated by the MetsubouJinrai Forceriser, the wearer's strength is increased by approximately 4.8 times.
  • Force Grab (フォースグラブ Fōsu Gurabu): The Lazarotech Suit's gloves. They increase grip strength and tactile sensitivity by a factor of approximately 3 by receiving the energy generated by the MetsubouJinrai Forceriser. In addition, the fingertips are protected by sharp armor and function as a lightning discharge device supplied by the Arm Stranger.
  • Force Leg (フォースレッグ Fōsu Reggu): Ikazuchi's legs. By receiving the energy generated by the MetsubouJinrai Forceriser, the wearer's leg strength is increased by approximately 6.4 times.
  • Chain Blocker (チェインブロッカー Chein Burokkā): Ikazuchi's segmented body armor. The Lost Model (ロストモデル Rosuto Moderu) of the overloaded Zetsumerisekey is forcibly attached to it. By protecting the parts of the body that are subject to impact with thick armor and cutting unnecessary armor, the total protection capacity is maximized while at the same weight. The Chain Blocker's arrangement allows it to easily move according to the wearer's movements.
  • Core Breast (コアブレスト Koa Buresuto): The central segment of chest armor. It is the chain blocker control unit. The status of each part of the chain blocker is monitored periodically to control energy distribution. Also, if the damage accumulated exceeds a certain limit, the transformation will be canceled to protect the user.
  • Arm Stranger (アームストレンジャー Āmu Sutorenjā): Ikazuchi's arm armor. The Lost Model of the overloaded Zetsumerisekey is forcibly attached to it. In addition to protecting the arm, it is equipped with a built-in lightning generator named the Strike Zapper (ストライクザッパー Sutoraikuzappā) and has the role of supplying lightning to each part of the body.
  • Leg Stranger (レッグストレンジャー Reggu Sutorenjā): Ikazuchi's leg armor. The Lost Model of the overloaded Zetsumerisekey is forcibly attached to it. It protects the legs and improves running speed and kicking power. In addition, by utilizing the strength of the armor, it enables activities in extreme environments that humans cannot set foot in.
  • Restraint Cable (レストランケーブル Resutoran Kēburu): Cables running through all parts of the body that transmit energy and information from the MetsubouJinrai Forceriser. In addition, taking advantage of their high toughness and ability to expand and contract freely, they have the role of constraining the utilized Zetsumerisekey's Lost Model and tightly binding it to the wearer.

This form has four finishers:

  • MetsubouJinrai Forceriser finishers:
    • Zetsumetsu Dystopia (ゼツメツディストピア Zetsumetsu Disutopia): Using the Valk Sabers, Ikazuchi launches two red energy slashes at the target.
    • Zetsumetsu Utopia (ゼツメツユートピア Zetsumetsu Yutopia): Ikazuchi unleashes a stream of red lightning from his hands.
  • Attache Shotgun finishers:
    • Kaban Shoot (カバンシュート Kaban Shūto): Through the use of a Progrisekey, Ikazuchi can boost his Kaban Shoot attack.
      • SpaceComing Kaban Shoot (スペースカミングカバンシュート SupēsuKamingu Kaban Shūto): Ikazuchi fires an energized arrow which leaves an insignia of Fourze upon hitting the target.
  • Legend Progrisekey Finisher:
    • SpaceComing Dystopia (スペースカミングディストピア SupēsuKamingu Disutopia): By pressing the SpaceComing Fourze Progrisekey, Ikazuchi summons Kamen Rider Fourze and the two performs Rider Rocket Drill Kick. Once hitting the target, the screen momentarily freezes to unveil "Youthful Galaxy" (青春銀河 Seishun Ginga) characters before it fades to show the opponent blew up and revealing the finisher's name in Katakana.

  • Ikazuchi is the first dodo-themed Kamen Rider in the Kamen Rider series.
  • Ikazuchi is the first Forceriser user to utilize a Zetsumerisekey instead of a Progrisekey.
    • Production-wise, he is also the first Kamen Rider to use a Zetsumerisekey, though chronologically Kamen Rider Ichi-Gata holds that title due to time manipulation by the Time Jackers.
  • Ikazuchi is the first Forceriser user to utilize its "Utopia" finisher.
  • Ikazuchi is the first Reiwa Rider who first appeared and died in the same episode.
  • Out of all of's members, Raiden appeared the least, only being alive for one episode and briefly appearing in another in the form of a flashback.
