History
Vision was the last member of the Avengers since Cerebro's genocidal campaign wiped out the other heroes in America. He allied with Machine Man and Ultron (whose electronic essence contained the life energy consciousness of Henry Pym) in saving humanity by fooling Cerebro in joining its cause and secretly modified the Machine Men armies in containing the life energies of every people killed in Cerebro's neutron-bombs. Vision and his allies planned in someday overthrowing Cerebro for good and restoring the energies of humanity into Life-Model Decoys. Though the task in defeating Cerebro proved barely impossible until the Exiles entered into their reality to stop the mad A.I.[1]
