Revol Bugster (リボルバグスター Riboru Bagusutā, Revolve Bugster) is the monster born from data of the shooting video game, Bang Bang Shooting. He is based on the data of Commander Revol, a boss from the stuck-in-development hell game.

Character HistoryEdit

First Fight with the Kamen RidersEdit

The Revol Bugster emerged when Yuki Kitami, a patient who was afraid of doctors, reached a high stress point by letting his fear overpower him. The situation was made worse by Emu, Hiiro, and Taiga trying to save him, scaring Yuki even more by transforming into Kamen Riders.

The infection spread as Yuki's fear reached its peak and nearly killed him, the Bugster becoming able to summon copies of himself to fight the Riders, but Ex-Aid risked his life and took on Revol's salvo of gunfire to convince Yuki to overcome his fear of doctors by telling him he was sincere about wanting to help him get better. After Yuki no longer felt stressed, the Bugster infection weakened; Revol was suddenly unable to summon more duplicates, and was seemingly defeated by Ex-Aid's Mighty Critical Finish. However, it was revealed that he had been a duplicate stand-in the whole time, and the real Revol was invisible and about to sneak-attack Ex-Aid, only for Kamen Rider Snipe to see though the monster's invisibility and shoot him down with his Bang Bang Critical Finish. BANG, That Jerk is Coming!

Level 5, Second AppearanceEdit

The Revol Bugster re-emerged when Nico Saiba, a patient with a vendetta against "Genius Gamer M", reached a high stress point when Taiga scolded her for stealing his Gamer Driver and Bang Bang Shooting Gashat. He summoned a group of his original Bugster Viruses, and they fought Brave and Snipe while Ex-Aid's attacks did nothing to him, likely owing to Emu being Nico's source of stress thereby rendering these Bugsters invulnerable to him alone. Genm Level X arrived to fight Ex-Aid, leaving Revol without an opponent, and then covered their retreat. Revol later tried to attack the Riders again, but was chained up on the sidelines by Parad to make way for his debut as Para-DX. A New Challenger Appears!

Revol and his soldiers later showed up to protect Emu from Brave trying to force out his Bugster infection, as Emu is the source of Nico's stress. Even when Emu joined the fight and attacked Revol, his attacks still miss. Revol escaped with Genm. He later reappeared to protect Emu from Snipe, attacking Emu only to draw out Revol, fighting him until Genm took over. Then Revol saw Para-DX defeating Ex-Aid Level XX. He reluctantly attacked Para-DX to defend the only thing that could lead to him becoming a complete being, but his attacks were too weak, and Para-DX destroyed Revol against Genm's order with a Knock Out Critical Smash for interfering with his "fun", his debris quickly being collected by Genm with the Gashacon Bugvisor. The Paradox Who Defeated M


Born from the data of Commander Revol, the Revol Bugster has great commanding skills. However, when comes the situation where things are beyond his control, he easily gets dumbfounded and confused. He's also scared of heights.

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).

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.

The Revol Bugster has a large machine gun named the Revol Arm (リボルアーム Riboru Āmu) on his right arm, a smaller machine gun over his left hand, and a canon on his back as his main weapons. He can turn his Bugster Virus soldiers into clones of himself, but only if the infection has enough of a grip on its victim. He also has the ability to turn invisible.

Revol later returns as a Level 5 Bugster, now with a new Gatling gun attached on the side of his face, manifesting into his monster form immediately from Nico Saiba, who has a deep hatred toward Emu Hojo. Since Emu was the one who gave her stress, he is the only one who cannot harm Revol and his Bugster Virus soldiers.

Appearances: Ex-Aid Episodes 15, 16
