I read in another topic here, I can't remember which, that mutants can't be added to the game because of the legal situation between Marvel and Fox. I understand that Fox owns the movie rights to anyone who is referred to as a "mutant" in the MCU, but not sure how this affects games. Does anyone know?
Beast is announced, so it seems possible. Maybe he was grandfathered in, I don't know, just curious. There are still a lot of Mutants I'd like to see. Bishop and Sinister already exist somewhat, Omega Red is a personal favourite, Holocaust from Age of Apocalypse, or even Apocalypse himself. There are tons.
