A seventeen year old orphan from the streets of Gotham City, Costner was infected with the O.M.A.C. Virus. As he lived off the grid, he wasn't activated during Brother Eye's endgame in Infinite Crisis. Michael wasn't activated until Brother Eye's last moments, but unlike other agents, he retained some control of his own will.
