There have been several versions of him appearing on worlds like Earth-Three, the Antimatter Universe, and the Crime Society universe. Each version has equivalent powers to Superman, but opposites reflected in their personal story. These include changes such as becoming stronger through Kryptonite as a Kryptonian. He's also been portrayed as a human astronaut named Clark Kent who receives power from aliens. His nemesis is the genius Alexander Luthor, and he's usually shown in a love triangle with Owlman and Super-Woman.
