who will be in avengers doomsday

For Avengers: Doomsday , Marvel has already lined up a huge ensemble cast, so we have a pretty clear picture of who will be in Avengers Doomsday , even though more surprises and cameos are very likely.

Who will be in Avengers: Doomsday?

Below are the major confirmed and strongly reported characters and actors as of early 2026.

Core Avengers and Allies

These are the familiar MCU heroes forming the backbone of the team.

  • Chris Hemsworth – Thor Odinson.
  • Anthony Mackie – Sam Wilson / Captain America.
  • Sebastian Stan – Bucky Barnes / Winter Soldier.
  • Paul Rudd – Scott Lang / Ant‑Man.
  • Letitia Wright – Shuri / Black Panther.
  • Winston Duke – M’Baku.
  • Tom Hiddleston – Loki.
  • Danny Ramirez – Joaquin Torres / Falcon.

Mini‑story angle: this lineup leans into a “new era Avengers” feel, with Sam’s Captain America and Shuri’s Black Panther stepping fully into the leadership spotlight while Thor and Loki bring the cosmic, mythic weight.

Fantastic Four in the Fight

The Fantastic Four are central to the story, especially with Doom as the big bad.

  • Pedro Pascal – Reed Richards / Mister Fantastic.
  • Vanessa Kirby – Sue Storm / Invisible Woman.
  • Joseph Quinn – Johnny Storm / Human Torch.
  • (A Ben Grimm / Thing casting has been widely discussed in fan lists, but is treated more cautiously in official-style roundups.)

In fan and forum discussions, people frame this movie as “Avengers + Fantastic Four + X‑Men vs Doom,” and the official casting strongly supports that vibe.

X‑Men and Mutants

One of the most hyped parts of Avengers: Doomsday is how many classic X‑Men it pulls in.

Confirmed and heavily featured mutants include:

  • Kelsey Grammer – Hank McCoy / Beast.
  • James Marsden – Scott Summers / Cyclops.
  • Alan Cumming – Kurt Wagner / Nightcrawler.
  • Patrick Stewart – Charles Xavier / Professor X.
  • Ian McKellen – Erik Lehnsherr / Magneto.
  • Rebecca Romijn – likely returning as Mystique (her involvement is listed among the ensemble).
  • Channing Tatum – long‑rumored as Gambit, now attached in cast lists for this film.

Forum and theory posts often describe this as the “true arrival” of the X‑Men into the main Avengers saga, not just multiverse cameos.

New Avengers / Next‑Gen Heroes

You also get the younger and “next‑wave” heroes, hinting at where Marvel wants to take things after Doomsday.

  • Florence Pugh – Yelena Belova / Black Widow.
  • Wyatt Russell – John Walker / U.S. Agent.
  • Iman Vellani – Kamala Khan / Ms. Marvel (mentioned in theory and cast-compilation lists).
  • Simu Liu – Shang‑Chi.
  • Hannah John‑Kamen – Ava Starr / Ghost.
  • India Rose Hemsworth – Love (Thor’s adopted daughter).
  • Cassie Lang / Stinger is also referenced via Kathryn Newton in fan and cast lists.

A lot of forum conversation compares this structure to Infinity War —with multiple squads operating in different corners of the story, then crashing together in the finale.

Wakanda, Talokan and Global Players

Doomsday pulls in more corners of the MCU to raise the stakes globally.

  • Tenoch Huerta – Namor.
  • Mabel Cadena – Namora.
  • Alex Livinalli – Attuma.
  • Winston Duke – M’Baku (also listed above with the core Avengers set).
  • David Harbour – Alexei Shostakov / Red Guardian.

These characters give the film that “worldwide crisis” feel rather than just being a New York‑centric showdown.

The Villain: Doctor Doom

The headline twist is who’s playing Victor von Doom.

  • Robert Downey Jr. – Victor von Doom / Doctor Doom.

Analysis videos and breakdowns point out the meta‑angle: casting the former face of the MCU (Iron Man) as the new ultimate villain plays right into the multiverse and “choice and consequence” themes.

What’s speculation vs confirmed?

  • Confirmed or strongly supported : Names that appear in official-style cast lists, major entertainment outlets, and credit pages (like Hemsworth, Mackie, Pascal, Kirby, Downey Jr., Stewart, McKellen, Grammer, Marsden, Cumming, Huerta, Harbour, etc.).
  • Fan-theory / forum speculation : Extra cameos, surprise Spider‑Man appearances, or deep‑cut mutants that show up mostly in theory subreddits and rumor threads.

Because Marvel loves late‑stage surprises, you can assume this isn’t the full picture yet—but if you’re wondering “who will be in Avengers Doomsday ,” the heroes and villains above are the core people you can count on as of now.
