If Scorpion had to be a skin, chains, guns, and grenades makes more sense than a grappling hook, batarangs, gliding, and the Batmobile.We don't even know how Lobo fights, so that seems too soon.
Killer Frost has some of the most feminine movements in the game which is why Captain Cold definitely isn't going to be a skin. Batman's animations are generic enough to work for Batgirl. I could see Supergirl and Power Girl working as Superman skins, too.I would hella be down for new 52 Captain Cold.
