I’d put in Longshot and Madelyne Pryor too to finish off the 9 for Fall of the Mutants and then they can either add in the Adversary too or just make the boss event around him like the Galactus one so we could get a boss with all of them.
Cannonball is my #1 choice for the game. We’re sorely lacking in old-school New Mutants, and he’s been in the X-Men and Avengers, and I think they could come up with some fun mechanics for his gameplay.
Monet and Dani Moonstar would be fun and bring some more women of color, which would be nice.
Mimic – either the original or, even better, the Exiles version, could be really interesting if they could figure out some clever ways to make his powers work (i.e., copying and activating one of his opponents’ powers).
