Steel

Steel is a movie starring Shaquille O'Neal, Annabeth Gish, and Judd Nelson. A scientist for the military turns himself into a cartoon-like superhero when a version of one of his own weapons is being used against enemies.
When a renegade military reject puts new superweapons in dangerous hands, John Henry Irons becomes Steel. Wearing body armor, wielding a fearsome electrohammer and riding a gadget-packed motorcycle, he's ready to wage war... if he can fix the untimely glitches in his untested gear.
