Hell no to any Marvel characters being added to the roster. Instead of trying to appeal to over zealous fan boys they should include characters like Vixen, Steel, Power Girl, Mr. Terrific, Doctor Fate, Silver Banshee, Gorilla Grodd, Atrocitus, Kalibak, and Cheshire.
Yeah, I just got the game, and with the "Ultimate Edition" it kind of looks like they are done with the game, but I would love to see more characters, I would buy them. I want Duela Dent (Ame-Comi) and Supergirl, plus as another said, Black Canary and Poison Ivy. :D
