After months and months of waiting, the first official Avengers: Doomsday trailer is finally here, and it looks like a thrilling return to form for the MCU after years of wheel-spinning post-Endgame.
The trailer, which appears to be identical to the one shown behind closed doors at CinemaCon earlier this year, opens with the voice of Doctor Doom himself ominously intoning: "Something's coming, something we may not be able to deter." Clocking in at 2 minutes and 25 seconds, the extensive first glimpse features the Fantastic Four meeting the Wakandans, Yelena facing off against shapeshifting mutant Mystique, Gamit going toe-to-toe with Shang-Chi and, of course, the return of Steve Rogers, who is still worthy of wielding Mjolnir despite hanging up the shield.
Although this isn't the first we have seen of the new movie, after a string of teasers were released earlier this year, the new clip gives us our first real look at the battle against the MCU's newest villain. It seems fitting that the first official Doomsday trailer would hit the internet the same week as San Diego Comic-Con 2026, marking two years since Robert Downey Jr. was unmasked as Doctor Doom. Marvel is due to take over Hall H yet again this year, where we hope to see more of the new Avengers movie.
The trailer arrives not long after the new synopsis appeared on Fandango, teasing the Multiverse Saga's "final chapter" as "beloved heroes from three distinct universes will be set on a deadly collision course and ultimately face an existential threat unlike anything they've ever encountered." The listing states that the new Avengers movie "will lay the foundation for the future of the Marvel Cinematic Universe."
Alongside the Iron Man star, who makes his Marvel return as the formidable villain Doctor Doom, Doomsday's stacked cast list includes Chris Hemsworth as Thor, Chris Evans as Steve Rogers, and the majority of the original Fox era X-Men, including Patrick Stewart's Professor X and Ian McKellen's Magneto. The new Fantastic Four and Thunderbolts will also appear, as well as the Wakandans and so many more.
Doomsday arrives this December 18. For more on Marvel Phase 6, check out our guide to all the upcoming Marvel movies and shows.
