This article is about a/an rider in Kamen Rider Ex-Aid.

Kiyonaga Hojo (宝生 清長 Hojo Kiyonaga) is the father of Emu Hojo and creator of the Bugster Virus.

Character History


Dr. Kiyonaga Hojo was the former president of a Medic Trick company that specialized in the manufacture of medical equipment. In anticipation of the Y2K bug and the possible effects it could have on his company's products, Dr. Hojo attempted to create a solution using samples of Bugster data. However after countless analytical simulations, Dr. Hojo would inadvertently create the original Bugster Virus.

At some point after the incident, Masamune Dan would contact Dr. Hojo with an offer to contract his company with the development of medical equipment which can be used to combat the Bugster virus if needed. Unfortunately for Dr. Hojo, Masamune would also obtain information connecting the doctor's involvement to the creation of the Bugster virus. Using this info, Masamune blackmailed Kiyonaga into assisting him in the development of "Kamen Rider Chronicle" which involved the release of his son Emu--Patient Zero--to Kuroto for Bugster separation surgery.

The series of events would cause Kiyonaga to separate himself from the situation, ending all association with the Dan family, including the Bugster virus and even his son. Dr. Hojo would remain missing ever since.


In a decisive confrontation to determine the fate of Mighty Novel X, Emu faced Genm Action Gamer Level 2 in a series of battles. Recalling the memories of his numerous encounters with Kuroto, Emu eventually realized that he was not facing the same person. Confronting this Genm with this evidence, the impostor declares in audacious tone, "I brought the Bugster Virus into this world! And I'll threaten many lives with it!"

Genm morphs, revealing himself to be Dr. Kiyonaga Hojo. He declares his intentions to defeat Emu and everything connected to the Bugster. But, in that moment, he expressed his remorse and guilt for his misdeeds; apologizing to his son at length, in an emotionally-charged dialogue.

The real Kuroto Dan II then appears, due to Kiyonaga halting the continuation of the game and using his Bugvisor II, vanquishes Kiyonaga.

Action Gamer Level 2 (アクションゲーマーレベル2 Akushon Gēmā Reberu Tsū) is Genm's primary fighter form, activated by inserting the Proto Mighty Action X Gashat and pulling the lever on the Gamer Driver.

Since he is a pallete swap of Ex-Aid, he shares the same ability parameters with Ex-Aid. However, Genm relies on brute melee attacks and long-range shooting rather than the agility and evasion seen with Ex-Aid.

This form has the following parts:

  • GM Head-ACT 2 (GMヘッド-ACT2 GM Heddo-ACT2) - Kamen Rider Genm Proto Action Gamer Level 2 Head.
    • Eye Light Scope (アイライトスコープ Ai Raito Sukōpu) - Kamen Rider Genm's "eyes". It can emit light for night battles and can also capture images comparable to a high- speed camera. It can also observe microscopic Bugster Virus.
    • React Signal (リアクトシグナル Riakuto Shigunaru) - It can capture and identify motion and set tracking markers automatically. The radar on the internal monitor shows the positions of enemies, allies and energy items.
    • Hard Ride Hair (ハードライドヘアー Hādo Raido Heā) - Kamen Rider Genm's "hair". It is modelled after the player character of Mighty Action X and is coated with a blast-resistant coating.
    • Dynamic Goggles (ダイナミックゴーグル Dainamikku Gōguru) - Kamen Rider Genm's goggles. It protects the visual sensors from shocks and dirt and is coated with a blast-resistant coating.
    • Sender Ear (センダーイヤー Sendā Iyā) - Kamen Rider Genm's hearing sensors. It filters surrounding noise so Ex-Aid only hears the necessary sounds. There is also a communication function for private conversations with specific parties.
    • Air Fresh Guard (エアフレッシュガード Ea Furesshu Gādo) - An intake system within the helmet that filters out harmful substances in the air. It also regulates the suit's temperature and allow for underwater breathing.
  • Mech Life Guard (メックライフガード Mekku Raifu Gādo) - Kamen Rider Genm's chest armor. It disperses damage throughout the body to protect the chest. It becomes more protective the lower the rider's health.
  • X Controller (エクスコントローラー Ekusu Kontorōrā) - Management module on the chest. It transitions to debug mode and systems control when activating the special attack.
  • Rider Gauge (ライダーゲージ Raidā Gēji) - A lifebar that shows the rider's health. When the gauge runs out, the rider will die.
  • Proto Gear Suit (プロトギアスーツ Puroto Gia Sūtsu) - Kamen Rider Genm's bodysuit. It increases the rider's physical capability by strenghtening the body. The agility focused adjustments increases the rider's reaction time and the rider's skills will be reflected as attack power. While it is possible to cancel the Strenghtening Limiter to become stronger, it will burden the rider's body.
  • Multi Unbreaker (マルチアンブレイカー Maruchi Anbureikā) - Kamen Rider Genm's shoulder armor. It injects a strengthening agent to raise the rider's defense for a short amount of time.
  • GM Growth Arm (GMグロウスアーム GM Gurousu Āmu) - Kamen Rider Genm's arms. It has a function called Gain Riser (ゲインライザー Gein Raizā) that increases combat capabilities based on the rider's level and combat experience. The arms allow for quick responses for complicated attacks.
  • Proto Fight Glove (プロトファイトグローブ Puroto Faito Gurōbu) - Kamen Rider Genm's gloves. It coordinates with the Gashacon weapons to optimize attacks. It also injects a Bugster removal program when executing punches to do more damage.
  • GM Growth Leg (GMグロウスレッグ GM Gurousu Reggu) - Kamen Rider Genm's legs. It has a function called Gain Riser (ゲインライザー Gein Raizā) that increases combat capabilities based on the rider's level and combat experience. Their high running speed allows the rider to attack quickly.
  • Proto Fight Shoes (プロトファイトシューズ Puroto Faito Shūzu) - Kamen Rider Genm's shoes. It enables acrobatic movement such as airborne flight, adjustment of drop timing, and two-step jumps. It also injects a Bugster removal program when executing punches to do more damage.
  • Mech Build Guard (メックビルドガード Mekku Birudo Gādo) - Kamen Rider Genm's grey guard pieces. The heat resistance rises when exposed to heat, and it becomes more durable by changing the structure of parts according to the damage received.

This form' finisher is the Mighty Critical Strike (マイティクリティカルストライク Maiti Kuritikaru Sutoraiku): Genm performs a series of kicks at the enemy.
