Motors Bugster (モータスバグスター Mōtasu Bagusutā) is the monster born from data of the racing video game where anything goes, Bakusou Bike. As recorded by CR, Motors is part of the Low Tier of Bugsters within Kamen Rider Chronicle: alongside Salty, Aranbura, Revol, and Charlie. The Forbidden Continue!?

Character History


The boss of the Genm Corp. game Mighty Action X, the character of Motors was conceived by Kuroto Dan, the teenage son of Genm CEO Masamune Dan. As a Bugster, Motors's origin is traced to the Y2K bug, which left what would be known as the Bugster Virus on the younger Dan's computer shortly following New Year's 2000. Secretly incubating the virus by infecting the young Emu Hojo with it, Kuroto Dan would arrange for its matured form to be extracted by Michihiko Zaizen ten years later, using it to execute the Zero Day incident in the following year.

Initial Emergence

Five years after Zero Day, the Motors Bugster emerged from Game Disease victim Yoshitaka Nishiwaki, who had been directly infected by Graphite upon his sister Riko's kidnapping. The stress over this eventually led to the Bugster virus taking hold into a giant wheel-like Bugster Union. The Union was destroyed by Level 1 Kamen Rider Lazer, the Motors Bugster forming and summoning a motorcycle, the Motors Viper, racing off.

He appears again when Emu and Kiriya attempt to reclaim Riko by winning the game in Kiriya's Bakusou Bike Gashat. He races Ex-Aid riding on Lazer, dropping spiky virus bombs and shooting exhaust flames. He pulls ahead at the end, but is knocked off his bike by an energy slash from Ex-Aid's Gashacon Breaker Blade Mode, being defeated by Ex-Aid using Lazer's Gashat for a Bakusou Critical Strike.

After the fight, the Motors Bugster is lying on the ground, smoking but alive (seemingly contradicting Yoshitaka's recovery), but before Kiriya can "examine the specimen", Kamen Rider Genm arrives and destroys him for good. An Operation Called Dash!

Level 5

He reemerges in a Level 5 form from Tsukuru Koboshi after he was forcibly infected by Kuroto Dan. Escaping the scene by outracing Ex-Aid despite him using a Speeding-Up Energy Item, he later attacks Genm Corp. headquarters to stress Tsukuru. Confronted by Ex-Aid again, he is told to step aside by Kuroto, watching him defeat Ex-Aid without transforming. Annoyed, he complains to Kuroto, only for Kuroto to assume Genm Zombie Gamer Level X, quickly dispatching the Bugster with a Critical End, absorbing his debris with the Gashacon Bugvisor. The Truth Exposed

The Bugster Horde

Motors was part of an perpetually reviving army of Bugsters which emerged in the real world as a result of Kuroto Dan's plot to revive in the Game World. This endless horde was held off by Kamen Riders Brave and Snipe, sharing the Gashat Gear Dual β and Hunter Gamer between each other, while Emu was sent from CR to the Game World to stop Dan. Maze 2: Escape Ultimately, the Bugster horde was suddenly dissipated in an instant as the destruction of the Game World brought about by Kazuma Kenzaki thwarted Dan's ambition to revive. Maze 3: Gorider Forever

Level 20

"I've evolved to Level 20, I'm super-supersonic now!"
―Motors Bugster Level 20[src]


Like his game character basis, Motors is arrogant and only cares about winning, using any sneaky trick to do so.


Bugster (Bacteria)

Bugster Virus bacterium.

The Bugsters originate as the microscopic Bugster Virus (バグスターウイルス Bagusutā Uirusu), a result of humans being contaminated by the Bugster, thus developing the condition known as the Game Disease (ゲーム病 Gēmu-byō).

Ex-Aid EP 4 Giant Virus

The spiked wheel-like Bugster Union that became the Motors Bugster.

The Bugster Union (バグスターユニオン Bagusutā Yunion) is the monster form of a Bugster-infected patient when the virus first flares up. When a Bugster-infected patient experiences enough stress, the Bugster Viruses inside multiply rapidly and overtake the patient's body, forming a giant orange virus form around it; the Union's shape seems largely irrelevant to the Bugster's appearance. Bugster Unions can only be defeated by a Kamen Rider in Level 1; the reason why is unexplained, though it may be because other Levels are too strong and may injure the patient inside the Union.

Powers and Abilities


Behind the Scenes


  • to be added


  • His personal motorcycle, Motors Viper is based on a Honda XR 250.
  • The Motors Bugster's tortoise motif is an irony, as tortoises are rather slow animals.
  • He is currently the only Bugster to have both an initial appearance and a Leveled-Up return each lasting only one episode.
  • When his Level 5 form was destroyed, there was no "Game Clear!" announcement. This may either be a production error or stem from the fact that defeating him in a race instead of destroying him is how Bakusou Bike was intended to be and was initially cleared.
  • His head slightly resembles GorminIcon-crosswiki's head from Kaizoku Sentai GokaigerIcon-crosswiki.
  • Coincidentally, both Motors and Lazer, the Bugsters and Riders from the same game are known for being manipulated and killed by Kuroto once their deed done. The former two's deaths as well are catalysts of Emu Parad to further resented Kuroto to the point of revenge. As of episode 29, this trait may not be a coincidence.
