Game History
Cancer Bubble is an optional boss. patrick rudolph, his human form, is in the Big Wave Shop. His EM form can be fought at AMAKEN.

Cancer Bubble returns as an optional boss. Claud once again shows up in the Big Wave shop and must be talked to fight his EM form, which appears at the Bunny Slopes ER. His attack pattern has not changed much since the previous game. Fighting him at least once grants MegaMan an Ability that modifies his Charge Shot.

Anime History
Cancer Bubble is an important FM-ian. He, in the end of the series and in episode 17, is the leader of most of the FM. He, with his Andromeda Key (fake) is trying to reborn Andromeda. He is also a fan of Sonia Sky.

Cancer Bubble appears in Tribe as Sonia's assistant, often attempting to help her deal with things while she is gone. He is more of a comic relief character, as his attempts to assist Sonia often fail humorously, and he fails badly in battle.

Attacks and Abilities

 * Bubble Pop - Cancer Bubble floats to and fro across the rows, firing a bubble along each column. The bubbles can be destroyed with a single Buster shot, and if they connect they induce a Bubble effect. In the second game, Cancer Bubble even hides crabs in some of his bubbles, and if broken the crab will rush down the column, dealing breaking damage.
 * Boomerang Cutter - Cancer Bubble stands at the back of the battlefield, and launches his claws at the player from the side, one at a time. The claws cannot be blocked and inflicts Bubble.
 * Tidal Wave - Cancer Bubble will summon a large 3x2 tidal wave which must be blocked to avoid damage. This attack inflicts Bubble.

Trivia

 * In the Japanese versions, Cancer Bubble has a habit of ending most of his sentences with "-buku", which is an onomatopoeia for a bubble being burst. This is probably a reference to BubbleMan.EXE from Battle Network, who ends his sentences with "-puku" in the Japanese versions.
 * In the anime, Cancer Bubble is distinctive among the FM-ians for wearing human clothes (not counting when they FM-ians are in their human form disguises); in addition to his natural appearance, he has also worn a number of extra outfits, including Claud Pincer's clothes, a medical mask, and even a trenchcoat.
 * Cancer Bubble has an attack called "Boomerang Cutter," which coincidentally is one of the abilities of X in Mega Man X.
