Marvel Studios officially released the first public trailer for Avengers: Doomsday on Monday, July 20, 2026. Following its exclusive debut at CinemaCon earlier this year, the footage finally gives fans a direct look at Robert Downey Jr. stepping into the role of Victor Von Doom. The internet immediately fixated on one specific climax in the footage. Thor leaps into the air and strikes Doom with a lightning-charged Stormbreaker. Doom doesn’t dodge. He just stops the axe with two fingers and barely reacts.
The display of power completely rewrites the MCU’s current hierarchy. Fans instantly drew comparisons to Avengers: Infinity War, where Thanos took a devastating blow to the chest from that exact same weapon. Eitri forged Stormbreaker specifically to kill the Mad Titan. Having Doom block it effortlessly establishes him as a distinctly superior physical threat, drawing direct parallels to Hela catching Mjolnir in Thor: Ragnarok.
We also finally heard Downey Jr.’s Latverian accent. It cuts completely through the old Tony Stark persona. But that wasn’t the only major reveal. Chris Evans officially returns as Steve Rogers in the footage, proving his identity across the multiverse by summoning Mjolnir on screen. Social media quickly erupted over the reveals, praising RDJ’s distinct voice and the updated character designs. Still, some viewers argued the pacing feels rushed. Doom is stepping in as the main antagonist for the Multiverse Saga following Jonathan Majors’ exit as Kang, and he hasn’t had the decade-long build-up Thanos enjoyed.
Directed by the Russo Brothers, the film hits theaters on December 18, 2026. It promises a heavy crossover event pulling heroes from three distinct universes, bringing the Fantastic Four and the X-Men into the fold. The studio is clearly accelerating its slate of interconnected team-ups, especially after the recent Brand New Day trailer teased Peter Parker recruiting Hulk and the Punisher. The multiversal stakes are officially set. Doom is here, and he isn’t sweating the Avengers’ heaviest hitters.
