There are many super hero media and stories in world besides the main ones (DC and Marvel). The most common superhero people think of is Superman from DC comics. As super heroes media spread from comics, tv shows, video games, and even movies many tried to made characters with same appearance, powers, and even origins as a the Man of Steel himself. So my question is to think as many Superman like characters as you can. They can’t be in same universe as Superman (Shazam and Martian Manhunter) or have to make appearances outside of comics.
