jeebs growing a new head

Jack Jeebs is a bizarre humanoid alien from both men in black movies. He works in a pawn shop and can alter his face to look like someone else and regrow his head after K shot it off. The only drawback to jeeb's abilities are his head never looks exactly the same after regrowing, he can't change his body or his voice, and his head takes several days to regrow and looks freakish during regrowth.
