Archangel

Warren Worthington III was born to a wealthy industrial family. But when he hit puberty, large, bird-like wings began to grow from Warren's back. Naming himself the Avenging Angel, Warren began a short-lived superhero career, before joining the Uncanny X-Men!

Sick of the ridicule regular humans caused towards mutants like himself, Angel joined up with Apocalypse, who recreated the hero into his Horseman of Death, grafting metal wings upon him, and turning his skin blue. Upon escaping Apocalypse's clutches, Warren was the Angel, no more. He was now Archangel.

Archangel has since shown the ability to shift between natural and metallic wings, as well as changing his skin color from caucasian to blue, at will.

Archangel defeated Omega Red in the opening round, but tied with fellow X-Man Cyclops in the second, eliminating them both.
