There was a lab accident, I think, and Tony is thrown into an alternate universe. In that universe Steve was the ultimate leader and he had lost Tony. He had Tony fitted with Extremis (I think) or had it rewritten somehow and he became pretty much a slave to Steve. He ends up back in his own universe but the changes were there to stay. Does that sound familiar? Thanks much.
