Avengers: Doomsday Update Unveils Captain America's Unlikely Dream Team

Marvel just slipped a pretty big tease overseas: at a Disney showcase in Italy, they put up slides for Avengers: Doomsday grouping heroes into teams. One of those teams? Sam Wilson leading a lineup that comes with a legit curveball.

So who is on Cap's team?

A slide at the event paired Sam Wilson's Captain America with Thor, Ant-Man, Shang-Chi... and Loki. Yes, Loki. The presentation also showed other groups like The Fantastic Four and the original X-Men, so this wasn't a one-off — they were clearly mapping out factions for the movie.

Wait, Loki?

That is the eyebrow-raiser. Last time we saw Tom Hiddleston's trickster, he wasn't exactly field-ready — he was parked at the Citadel at the End of Time, basically acting as the engine keeping the multiverse intact after Loki season 2. How he goes from cosmic time-weaver to boots-on-the-ground Avenger is unclear, but Doomsday is apparently where Marvel will lay out those receipts.

Where this came from

The footage and slides were part of a Disney event in Italy, with attendees noting the multiple team lineups and posting about it after. An Avengers fan account even flagged the Doomsday showcase on December 2, 2025. So this is one of those 'not a trailer, but not nothing' studio teases.

Who else is in this thing

Marvel has quietly (and not-so-quietly) stacked the cast. Here is everyone the studio has lined up or shown on those slides so far, grouped by how they were referenced:

• Officially on board: Chris Hemsworth as Thor; Pedro Pascal as Reed Richards; Vanessa Kirby as Sue Storm/Invisible Woman; Anthony Mackie as Captain America (Sam Wilson); Sebastian Stan as Bucky Barnes/Winter Soldier; Letitia Wright as Shuri/Black Panther; Paul Rudd as Ant-Man.
• Also in the mix: Wyatt Russell as John Walker/U.S. Agent; Tenoch Huerta as Namor; Ebon Moss-Bachrach as Ben Grimm/The Thing; Simu Liu as Shang-Chi; Florence Pugh as Yelena Belova; Kelsey Grammer as Dr. Hank McCoy/Beast; Lewis Pullman as Bob/Sentry; Danny Ramirez as Joaquin Torres/Falcon; Joseph Quinn as Johnny Storm/Human Torch; David Harbour as Alexei Shostakov/Red Guardian; Winston Duke as M'Baku; Hannah John-Kamen as Ava Starr/Ghost; Tom Hiddleston as Loki.
• Returning X-Men faces: Patrick Stewart as Charles Xavier; Ian McKellen as Magneto; Alan Cumming as Nightcrawler; Rebecca Romijn as Mystique; James Marsden as Cyclops; Channing Tatum as Gambit.

The takeaway

Sam Wilson captaining a squad with Thor, Ant-Man, Shang-Chi, and Loki is a fun, slightly chaotic combo — and the Loki piece is the weird wrinkle that could hint at how deep into multiverse mechanics Doomsday plans to go. Between that and Marvel dusting off classic X-Men alongside the Fantastic Four, this movie is clearly designed as a big tent crossover.

Release date

Avengers: Doomsday is currently set for December 18, 2026.
