Charlie Bugster (チャーリーバグスター, Chārī Bagusutā) is the monster born from the data of the bike-themed video game, Shakariki Sports. As recorded by CR, Charlie is part of the Low Tier of Bugsters within Kamen Rider Chronicle: alongside Salty, Aranbura, Revol, and Motors. The Forbidden Continue!?



Charlie is the boss of the Genm Corp. game Shakariki Sports, conceived by Kuroto Dan. As a Bugster, Graphite'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.

Initial Emergence

Over five years after Zero Day, the Charlie Bugster emerged from Kuroto Dan himself, having infected himself with the Bugster virus to get away from the Ministry of Health raid on his hideout. Charlie overtook his body and rode around a skate park on a bicycle to attack the Ministry personnel until Ex-Aid Double Action Gamer Level XX arrived. Ex-Aid was unable to catch up with Charlie, so Level XX L distracted him while on the Sports Gamer with an Instigate Energy Item, leading him around the park and back into Level XX R, who knocked Charlie down with the Gashacon Key Slasher. Charlie retreated back into Kuroto, but later resurfaced to face Ex-Aid Level XX again, this time being quickly defeated by Mighty Double Critical Strike. His debris were immediately collected by the freed Kuroto with the Gashacon Bugvisor.

Kamen Rider Chronicle

Charlie was revived among an assembly of all component Bugsters through the Gashacon Bugvisor by Parado as he commenced Kamen Rider Chronicle, in which Charlie would serve as the boss representing Shakariki Sports.

Charlie was engaged by Teruyo Izumi, who became a Ride-Player to restore her son. Charlie easily overpowered the Ride-Player but was intercepted by Ex-Aid, who pursued him with the Maximum Gamer before Nico Saiba arrived to defeat the Bugster with the Nico Critical Punch, claiming the Gashatrophy of Shakariki Sports.


Charlie is very energetic and often shouts short English phrases. He is very skilled at biking, but can be distracted easily, not noticing Ex-Aid Level XX R waiting for him when chasing Level XX L, though the effects of the Instigate Energy Item may have affected his focus in this instance.


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).

Concept Art

Charlie Bugster concept art

Charlie Bugster was designed by Katsuya Terada (寺田 克也, Terada Katsuya).


  • Charlie is so far the only Bugster from an armor-themed Rider Gashat not to be used or inheriting his feats to a Collabos Bugsters.
  • Charlie's host is Kuroto Dan, the initial user of the Gashat whose game he is taken from. In-universe, however, this is merely a coincidence.
