This here's Scrounge, he's an obscure Transformer from the 80's Marvel comics.
He is basically a cannon-fodder character who gets his arm ripped off, and then gets melted. Poor guy. He transforms into a wheel. Ooh.
As far as I know, noone has ever made a toy of this guy.
(Forgive the roughness of the pic, it's only a pencil sketch, I rarely get round to inking my stuff, and tend to destroy them when I get round to colouring)
