Iron Man becomes Doctor Doom

In one small iteration. I actually think it might be a red herring to be honest: I think RDJ is going to be a Doctor Doom variant from a timeline where Tony didn't become an Avenger (basically events of Iron Man 1 never happened).

But, I think it'll lead into the introduction of the "main" Doom, and RDJ returning as Iron Man for the 2nd Avengers in this phase. Maybe even RDJ's Iron Man killing off RDJ's Doom variant.
