Avengers: Doomsday cast
The roster spans three eras of Marvel cinema: the MCU regulars, the Fantastic Four cast from First Steps, and a Fox-era X-Men contingent that would have been unimaginable on one call sheet five years ago. Every name below is labeled by status, because the difference between announced and reported matters.

Reported, not on the official list
These names come from marketing appearances and trade reporting. Until Disney updates the cast list, treat them as very likely rather than confirmed. We label them because a cast page that fudges this is worthless.

- Ryan ReynoldsDeadpool
same marketing campaign as Jackman; widely accepted via trade reporting.

Where these characters come from
Nearly every name above traces to a title on our timeline. The Thunderbolts contingent (Pugh, Pullman, Stan, Russell) comes straight from Thunderbolts, the First Steps four from The Fantastic Four: First Steps, and the Fox cast from the X-Men saga. The prep list that covers all of them is on the Before Doomsday guide, and thetracker counts down your remaining hours before release.
Casting updates for a film this size keep moving. This page was last checked August 28, 2026; when Disney publishes an updated cast list, the reported section collapses into the announced section and the date at the top moves.
Common questions
Who is the villain in Avengers: Doomsday?
Doctor Doom, played by Robert Downey Jr. The Fantastic Four: First Steps post-credit scene introduces him with Franklin Richards; it does not show a crossing into the main MCU timeline.
Is Hugh Jackman in Avengers: Doomsday?
He and Ryan Reynolds fronted the SDCC and D23 2026 marketing for the film. Disney official cast list had not been updated to include them as of August 17, 2026, the day IGN covered the prep list.
How many actors are in the Doomsday cast?
25 announced names plus 4 reported. The three-eras framing is the story: MCU regulars, the First Steps Fantastic Four, and the Fox X-Men.
Is Robert Downey Jr. back as Iron Man?
He is back at Marvel, as Victor Von Doom. Everything announced so far points to Doom variants, not a Tony Stark resurrection.
