Hank McCoy (Beast) (you know its bad when only time-travel can resolve it)
Moira MacTaggert (she's basically a moustache twirling villain now)
Charles Xavier (this is still developing but I don't have hope)
Mr. Sinister (the current Gillen version of Sinister is more annoying than anything else and he's overexposed, the character was much more interesting when he was operating in the shadows)
