Robert Downey Jr. Rumored to Return as Doctor Doom in ‘Avengers: Doomsday’

The Doctor Doom character featuring Robert Downey Jr. in the upcoming Avengers: Doomsday movie has created an intense reaction among Marvel fans. The internet hosted photos on April 14, 2025 that showed Downey wearing Doctor Doom’s green costume including his hood, cape, and chest plate with power source design.

The piece presents an ingenious concept by transforming Robert Downey Jr. from Tony Stark to Victor Von Doom in an alternate timeline through his Marvel Cinematic Universe journey. This new concept fits with how Marvel uses their Multiverse Saga to investigate many worlds and their uncertain characters.

In a recent interview Kevin Feige confirmed Doctor Doom as Marvel’s number one villain and disclosed Robert Downey Jr.’s portrayal of the character. A new movie scheduled for 2026 will create a final superhero union between multiple teams.

Photos shared in public show that James Marsden and Ian McKellen will work on the film despite concurrent Doctor Doom information leaks. People become more eager to see major multiverse action because of this news.

Recent leaks give information about new Doom armor enhancements and two Downey renditions through platform artwork:

• New Doom armor borrows technology from Iron Man in its design for a modern approach.
• The depictions display Downey in his true appearance plus a version with white hair and beard.
• People spread the idea that Doom comes from his comic book roots as a stylish person who would wear highly fashionable outfits.
