This version of the Venom Symbiote, is first seen in a test tube in one of Iron Man's labs at Stark Tower. Dr. Pym was in charge in finding a way to adapt it for use to outfit Stark's new armors with. Pym's experiments on the symbiote has pretty much destroyed what conscious it had left but it was able to retain its biological properties of replacing missing limbs. During the period where Stark held the Dark Avengers, June Covington telepathically manipulated Pym into helping her restore her teammates to fighting form. They took the symbiote and used it to replace John Walker's missing arm and leg allowing him to become U.S. Agent once again.
