Who Is in the Avengers: Doomsday Cast? All the Confirmed Actors So Far
The Avengers Doomsday cast has been officially revealed, and it features some of Marvel’s biggest names, shocking character revivals, and the return of legendary actors from past franchises.
Marvel Studios president Kevin Feige unveiled the film’s new title, Avengers: Doomsday, during San Diego Comic-Con in July 2024. Directors Anthony and Joe Russo, famous for helming Avengers: Endgame and Infinity War, are back to lead this massive crossover, set to release on May 1, 2026.
Perhaps the most jaw-dropping announcement was Robert Downey Jr.’s return to the MCU—not as Iron Man, but as Doctor Doom, the film’s central villain.
With the X-Men, Fantastic Four, and Thunderbolts joining the Avengers, Doomsday is shaping up to be the most ambitious Marvel movie yet. Here’s the full list of confirmed cast members.

Robert Downey Jr. as Doctor Doom – Marvel’s Boldest Move Yet
Downey’s casting as Doctor Doom is one of the most surprising changes in the MCU. Instead of reprising his role as Iron Man, he will now play one of Marvel’s most iconic villains.
At Comic-Con 2024, Downey stepped on stage wearing Doom’s green robes, teasing his role with the phrase:
“New mask, same task. What did I tell ya? I like playing complicated characters.”
The Russo brothers have since praised Downey’s dedication, revealing that he has been deeply involved in shaping Doom’s backstory.
Notable Absences – Who’s Missing from the Cast?
While Avengers: Doomsday is packed with stars, some major Marvel characters were not included in the announcement:
- Spider-Man (Tom Holland) – Currently filming another Spider-Man movie
- Doctor Strange (Benedict Cumberbatch)
- Star-Lord (Chris Pratt) and the Guardians of the Galaxy
- Hulk (Mark Ruffalo)
- Hawkeye (Jeremy Renner)
It’s unclear whether they will join the film later, but their absence has sparked speculation.
What This Means for the MCU
With the Fantastic Four, X-Men, and Thunderbolts now joining the Avengers, Avengers: Doomsday is set to reshape the Marvel Cinematic Universe.
This all-star ensemble marks a new era for the MCU, setting the stage for Avengers 6, which is expected to follow Doomsday in 2028.
