Undoubtedly the biggest story to come out of this year's San Diego Comic Con was the news that Robert Downey Jr. will be returning to the MCU, albeit in a new role: Doctor Doom.
The mystery of how and why Doom will be played by the former Iron Man actor has stirred up much speculation, with some suggesting that this Doom will be a variant of Tony Stark, and others wondering if the forthcoming Avengers: Doomsday movie will draw on Brian Michael Bendis and Alex Maleev's Infamous Iron Man comic, which saw Victor Von Doom step into Tony Stark's metal shoes. Now one of Marvel's key writers has suggested that an answer to the mystery may be forthcoming in The Ultimates #4.
