Specter(Dallas Gibson, Marvel)

Not much is known about Specter's past, but after he accidentally scared his grandfather to death, he ends up at Xavier's Institute. He has the power to turn into a living shadow, which affords him superhuman strength and speed, near invulnerability, night vision, and immunity to darkness-based attacks. He is a member of the first team of the Hellions Squad, but once the training squads are official he switches to the Paragon Squad, and then again to Cyclops's Corsair Squad.
