Evil Xavier

"Evil Xavier" is the un-official name of a villainous alternate-version of Xavier who appeared in an Exiles storyarc - he was a deranged anthrophobic terrorist who sought to commit genocide against the human race and was imprisoned as a result: when the Exiles came to his world they believed that he was a victim of human oppression and set him free only to get a nasty surprise when they realised they had unleashed a monster - "Evil Xavier" proceeded to knock the group out using his powers and went on a rampage.
