Little is known about Psyback, except that he was kidnapped by Black Messiah at a young age and experimented upon for years. He was also forced to help them hunt down those whom Black Messiah deemed their enemies including James Cummings. Somehow, James convinced Psyback that helping stop Black Messiah would be the best way to help rid himself of his powers and help right the wrongs he's commited.
POWERS: Apparently Psyback is what some would call an anti-telepath! He can disrupt any form of telepathic commuincation or powers and create a psi-backlash. He also can create specialized weapons inwhich to add his own mental energy into to cause this effect also, even to non telepaths. His speed and endurance have also been enhanced to some degree, and he's been known to display some mental abilities like casting illusions of his own.
