First Appearance ???

 Brainmatter, pronounced bray-n-matt-ur, is a fusion of Grey Matter and Brainstorm's DNA. It can be accessed by any Omnitrix that allows fusions.


Brainmatter maintains Grey Matter's body build; he is extremely small and skinny. He has large, green eyes with horizontal lines as pupils. A black stripe with green in the middle runs down the middle of his face, all the way to his mouth, which is always a frown. He has six whiskers on his cheeks and chin. He has a black neck and black sockets that connect to his arms, which look like a crabs'. He wears a green omnitrix belt that resembles a jock strap, and has ankle braces on. His body is a brown metal.
