Then there’s the Thunderbolts* (aka New Avengers): John Walker/US Agent (Wyatt Russell), Yelena Belova (Florence Pugh), Bob/Sentry (Lewis Pullman), Red Guardian (David Harbour), and Ghost (Hannah John-Kamen). And the Fantastic Four: Reed Richards (Pedro Pascal), Sue Storm (Vanessa Kirby), Ben Grimm (Ebon Moss-Bachrach), and Johnny Storm (Joseph Quinn). We’ll also see Charles Xavier (Patrick Stewart), Beast (Kelsey Grammer), Magneto (Ian McKellen), Mystique (Rebecca Romijn), Nightcrawler (Alan Cumming), and Cyclops (James Marsden).

For good measure, Marvel threw in Gambit (Channing Tatum) and Xu Shang-Chi (Simu Liu). There will be plenty of cameos, like Steve Rogers (Chris Evans), revealed in one of four sneak teasers last year. We can also expect to see (at least briefly) Peggy Carter, Spider-Man (Tom Holland), Hawkeye (Jeremy Renner), Doctor Strange (Benedict Cumberbatch), Thor’s adopted daughter Love (India Rose Hemsworth), and Scott Lang’s daughter Cassie (Kathryn Newton).

So what’s in the trailer? A heck of a lot of cameos, mostly, as the superheroes from the three universes meet each other over an ominous voiceover by Thor warning of an unprecedented threat. “I’ve fought with many warriors in my time,” we hear Thor say. “They were far stronger than all of us put together. And they died. They died facing enemies and threats that scared me far less than this one. Everything that they sacrificed will be for nothing if we do not stand together. Put aside your petty squabbles and presume nothing except this. If you return, you will return as brothers and sisters. But mark my words, we’re going to need a miracle.”

OK, not exactly the St. Crispin’s Day speech, but the trailer ends with the return of Steve Rogers—and guess what, he’s still worthy of Thor’s hammer, Mjölnir. Could he be the miracle they need? Or is another miracle waiting in the wings?

Avengers: Doomsday hits theaters on December 18, 2026. Avengers: Secret Wars is currently slated for release on December 17, 2027, and will mark the conclusion of the MCU’s Phase Six.
