Noah Black was a brilliant geneticist who was awarded a Nobel Prize in the 1930s. He exiled himself to a deserted island, where he created his own Valhalla from evolutionary experiments. Convinced that the Earth had to be rebooted, he developed a plan to assail the world with radioactive radiation, eliminating all life on earth and then recommencing the evolutionary process. He was defeated by Nick Fury and Jimmy Woo.
He was remanded to the superhuman prison The Raft, where he is being considered for the Thunderbolts back-up team.
