History
Redstone was a member of Earth's super hero team, the Squadron Supreme led by Hyperion. He and his fellow Squadron members were sent to stop the incursion of their world from colliding with another Earth. By the time the two worlds were about to touch, solar flares engulfed every member of the team including Redstone which resulted in their death. Hyperion was the only survivor as he was pulled from his universe into that of Earth-616.[1]
