Is the real Tony either dead or in a coma? If so, who is this Tony that we saw in Secret Empire? It seems to be some kind of A.I (Artificial Intelligence.) version of him, how did this come about? I assume that the original Tony will come back in the near future, but I'm confused about the Tony that we currently have. Thanks.
Stark is in a coma. He endured injuries that would have killed a human, but Stark has performed multiple experiments on himself, making him something of a de facto Frankenstein. The A.I. was, irrc, something Stark invented to help Riri in the event of his death or debilitation.
