Robert Downey Jr. is returning to the Marvel superhero world after five years, but not as Iron Man. Instead, he will portray Dr. Victor Von Doom, a significant villain in the comic book series. Downey Jr. will appear in Avengers: Doomsday, set to release in May 2026, followed by Secret Wars a year later. The announcement was made at Comic Con in San Diego, where Downey Jr. appeared on stage dressed as Doctor Doom before revealing himself.
