Karma vs. Gladiator
According to Professor X he could just shut anyone off if he felt like it.
Karma needs only to see someone or know where that person is to possess them.
I think Karma takes control of Gladiator and defeats any other enemies around her...except for Vulcan.
this Vulcan guy that Gladiator beat the first time seems to be the real deal. I think he can really defeat Gladiator only as he's new he's yet to learn what to expect and what he's capable of.
