Foxx (Mystique)

Mystique has long dislike Remy, more likely than not because of his interest in Rogue and the fact that she does not think that he is good enough for her adopted daughter. She has tried to kill Remy more than once and he returned the favor after Mystique had killed Moira McTaggart.

All of this came to a head recently when Mystique infiltrated the Xavier Mansion disguised as Foxx, a new student, aiming to drive a wedge between him and Rogue. At first she tried to seduce Remy as Foxx, however when that didn't work she offered Remy the one thing she thought that he couldn't refuse, a night with her in Rogue's form. It isn't known whether Remy actually took her up on that offer, however Mystique’s plan succeeded and she managed to set Rogue and Remy against each other once more.
