Description Mutant GI Mauler and Shredder’s #1 Thug Rocksteady’s tough rhino body makes him a turtle-bashing powerhouse. His lack of smarts makes him dangerous. This mutant mammal is big trouble with his Retro-Mutogen Gun: one shot can level a whole building or a shelled turtle. Off-duty, Rocksteady loves to fry up a mess of juicy Turtle burgers for the whole hungry Foot clan. Rocksteady’s fieldglasses survey the area for anything that looks like a Turtle. (He’s mistakenly blasted six soccer balls). This G.I. rockhead blatantly displays his victory kills with the Turtle scalps he wears around his belt. 1988
