Still paying for last night, I'll make this quick.
Female Villain will be
Madelyne Pryor
Evil clone of Jean Grey.
From Wiki
As a clone of Jean Grey, Madelyne Pryor also possessed mutant abilities of
telekinesis and
telepathy. These powers remained latent while she was believed to be a baseline human, but later manifested in ways that Jean's never had. As the Goblin Queen, her mutant powers were exponentially enhanced by demonic eldritch magic to the point where she could
warp reality within a localized area.
Pretty sweet. Story has been retconned a lot, but I'm going with the Goblyn Queen version, that's what I remember.
