Man, I LOVE this design for the nameless Two-Headed Mutant!
I combines two of the nameless punks in Rocksteady & Bebop's original gang, making me wonder if Playmates thought about using that design for a potential new character. Looks like the Mohawk guy with the metal straps got mutated with a Fish [EDIT: oh, maybe it's actually a lizard or snake] and the dopey looking guy in the Andy Capp hat & 50s leather jacket got mixed with an ant eater or something!
