“New mask, same task.” Avengers: Doomsday. In theaters May 2026.

The MCU has just cast its Doctor Doom for the upcoming film Avengers: Doomsday, and it's...wait, Robert Downey Jr.?

At San Diego Comic-Con during the Marvel Studios panel, it was announced that Downey Jr. would be returning to the MCU not as Iron Man, but as Doctor Doom in Avengers 5, which is now known as Avengers: Doomsday. Downey Jr. made an appearance at the end of the panel flanked by Doom Bots, saying he'd "see you in two years" with Doomsday. The film is slated for May of 2026.
