Gatton Bugster (ガットンバグスター Gaton Bagusutā) is the monster born from data of the fighting robot game Gekitotsu Robots, and is based on its final boss, Gatton.

Character HistoryEdit

He arose from Mai Yamato's infection, possessing her body without breaking out to dance the Robot through the streets, only fully emerging when confronted by the CR Riders. He overtook her body like a Bugster Union and fought Ex-Aid Robots Action Gamer Level 3. Overwhelmed by his use of Iron-Body and Muscular Energy Items, Gatton retreated into Mai's body to recover.

He later reemerged to target Mai's dance performance hall, but was brought into another battle with Ex-Aid before Genm Zombie Gamer Level X interrupted. Brave Fantasy Gamer Level 50 then entered the fight, throwing Gatton around with mystical telekinesis and various other attacks before hitting both him and Genm with Taddle Critical Slash, destroying Gatton and freeing Mai. Gatton's debris were collected by Genm into the Gashacon Bugvisor to help complete Kamen Rider Chronicle. A Sudden Fantasy!?


He acted like a robot much of the time, moving in short, jerky motions and saying his own "vree" sound effects in addition to the piston sounds his body already made while moving. He would also speak in a very technical manner, bluntly stating his action before taking it.

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).

Emerging from Mai Yamato's Bugster infection, he was visible in full form during the Game Scope's diagnosis, a first for Bugsters. Despite skipping the Bugster Union stage like other strengthened Bugsters, he took possession of his host like a Union would instead of forming a separate entity, another sign of the Bugster virus's evolution.

Appearances: Ex-Aid Episodes 19

Powers and AbilitiesEdit


Gatton is armed with the same right-hand fist as the Gekitotsu Collabos Bugster, as well as a left-hand piston that can fire energy blasts.
