A tail of an echidna, ears of a bat, claws of a demon, fur off a bear, long red hair, he is amess, but since he was a lab rat for non stop expriments, he wasn't gonna turn out pretty, the gates that seperate the realities/universes in mobius is what he is after, destroys the reality around them and goes from one to the other, with his calm but vicious voice sends a chill down your back as he mocks the reality around you and destroys it with ease, his hatred goes deep and can't be swayed, the obvious heroes stop him and sonic, shadow and silver chaos control to warp them back before he existed and stopped the scientists but not before one of them self destruct the lab, along with karawan = the name they gave him, he can't remember his real name but names were not important to him.

Also this is his first form.
