Cancer is a FM-ian based on the constellation Cancer, the crab. He is partnered to Claud Pincer and the two can wave change into Cancer Bubble.


Compared to fellow FM-ians, Cancer is rather small in appearance with only Crown being comparable in term of size. His body is composed of teal-colored wave and red armor as his main body and pincers. The main body also has a small mouth and a crab-shaped emblem on it with a pair of eyes extending from the top. Each of the pincers also have blue stripe on it. Unlike normal crab, Cancer only has two legs.


Game History
