We always talk about who's gonna get in, when we should talk about who SHOULD NOT get in.
My vote goes for Emma Frost, Selene or any of the other queens of the hellfire club. Mainly because they will be wearing a censored safehorny PoS costume that is not sexy at all.
I can forgive Kamala since she is still a relative newcomer and at least Gurihiru tried to make her cute instead of sexy, and Storm's costume is a good enough fusion of her 90's white bodysuit and the leotard one. But theres no way in hell Emma is gonna wear something like pic related, so its pointless for her to be in any game.
