Michael O'Toole, also known as Steamroller, is a member of the U.L.T.I.M.A.T.U.M., an anti-nationalist organization led by Karl Morgenthau's daughter Karli. As a right-hand man, he was involved in helping Karli in her plan to return Earth's governments and society to how it was in between the Snap and the Blip. Eventually, Michael would go on to assist in Karli's attacks against the C.S.A. across Europe and later the United States of America. He was apprehended in New York City after the failed attack on the C.S.A., but was able to escape with the help of Paulus.
Following the apparent death of Karli Morgenthau, Michael abandoned his allegiance to the U.L.T.I.M.A.T.U.M. and would go on to walk a different way since he had been furious over Karli's brutal tactics.
