Aeroika fought alongside the Defenders (Hulk, Namor and Dr. Strange) to rid the Tunnelworld of the threat of the Unnameable. He is a messiah figure in his race who figured into prophecies that would lead to his race freedom.
Aeroika possesses no known powers. The wings on his head are vestigial, a reminder that their vulture-men captors would never let them be free. He was skilled in melee combat.
