Cancer Bubble

Cancer Bubble (キャンサー・バブル) is the combination of the characters Claud Pincer and Cancer from the MegaMan Star Force series.

He is capable of the following abilities and attacks:
 * 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.
 * Tidal Wave : Cancer Bubble will summon a large tidal wave which must be blocked to avoid damage.

MegaMan Star Force
Cancer Bubble is an optional boss. Claud Pincer, his human form, is in the Big Wave Shop. His EM form can be fought at AMAKEN.

MegaMan Star Force 2
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.

MegaMan Star Force Anime
Cancer Bubble is a important FM. He, in the end of the series, the leader of most of the FM. He, with his Andromeda Key (fake) is trying to reborn Andromeda. He is a fan of Sonia Strumm.

Shooting Star Rockman Tribe
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.

Trivia

 * Cancer Bubble actually has a big fan base. Many say he is cute and loveable.
 * 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.
 * Cancer Bubble also bears a resemblance to Bubble Crab of Megaman X2
