Steelman of Earth-X
When Jimmy Olsen is accidentally teleported to a parallel world called Earth-X, thanks to Professor Potter, he gains Superman-like powers and fights crime as Steelman, who wears a costume that is a combination of Superman's and Batman's costumes. Superman eventually takes Jimmy back to Earth-1 (SPJO No. 93, Jun 1966: "The Batman-Superman of Earth-X!" and "Steel-Man's Last Stand!").
