X-Men: Marvel Gives Charles Xavier a Dangerous Mister Sinister Connection

Longtime X-Men nemesis Mister Sinister has been trying to take out selected members of Krakoa’s governing Quiet Council — a body on which Sinister himself sits — in an attempt to reshape reality to his liking, as seen in the pages of Immortal X-Men. In doing so, the villain has just kicked off the pending Sins of Sinister event, and he’s begun by taking control of the X-Men’s founder himself, Charles Xavier.
