The Atom

With the character getting more recognition these days thanks to DC’s Legends Of Tomorrow, adding The Atom to the game just seems smart. Like Beast Boy, he also has a very refreshing power that would be fun to play. Being able to change your size mid fight from big to small could make him one hell of a combatant.

Something tells me NetherRealm would make the character look similar to the one in the show. I personally hope they go with more of the comic book look.
