I don't know if you guys like this sort of stuff, but:
D Fighter, a 2-D fighting game with 36 DC Characters if you count the secret ones, including popular picks such as Superman, Batman, and Wonder Woman, lesser known entities such as Captain Atom, Plastic Man, and Guy Gardner, and the downright obscure such as Felix Faust and Cir-El. Here's an easy way to access the secret characters: When you download the game, go into the 'Characters' folder, and then open 'clist.cfg'. Change the number at the top to '36'. Then add the following:
Characters\superrs.id
Characters\batrr.id
Characters\cirel.id
Characters\prime.id
Characters\para.id
Characters\rv2.id
