Xavier Demon is one of at least ten corrupted alternate-reality Charles Xaviers that serve as the primary antagonists of the X-Force and is a demonic version of the mainstream Xavier that has wiped out all life in his native reality, luring new victims in by casting the illusion of friendly unicorns to distract from his true nature.


  • The idea of Xavier Demon populating his world with illusionary unicorns may be a tongue-in-cheek reference to the My Little Pony craze, though this has not been proven thus should not be seen as "official".
