I think they could make a Green Arrow and Flash and Wonder Woman and Aquaman game pretty easily too. Especially Green Arrow.

Bizzaro could be one of the Superman villains, Mr. Mxyzptlk could be like Superman's Riddler. Depending on the story there could be a Phantom Zone breakout which would unleash evil Kryptonians and other criminals.
