A fourth promotional trailer for 'Avengers: Doomsday' has reportedly leaked online, sparking fresh excitement and intense speculation among Marvel fans ahead of the film's December 2026 release. The leaked teaser surfaced shortly after the third official trailer and quickly spread across social media before being taken down. Interestingly, the footage does not feature a full reveal of Victor von Doom, despite widespread anticipation around Robert Downey Jr.'s casting as the iconic Marvel villain.
Instead, the teaser appears to focus on a potential crossover involving the Black Panther legacy and the Fantastic Four, hinting at major alliances forming in the Marvel Cinematic Universe's next large-scale event.
What the Leaked Trailer Shows
According to fans who managed to watch the leaked footage, the trailer includes several visually striking moments that suggest interaction between Wakandan characters and members of the Fantastic Four. While exact scenes remain unconfirmed due to the clip's swift removal, the emphasis appears to be on world-building and cross-team dynamics rather than introducing the film's central antagonist.

The absence of Doctor Doom is particularly notable given earlier speculation that Marvel would heavily promote Downey Jr.'s involvement early in the marketing campaign. While his casting has generated enormous buzz, the studio seems to be taking a slower, more calculated approach by spotlighting its heroes first and leaving villain reveals for later trailers.
Fan Reactions and Online Buzz
The leak has triggered mixed reactions among Marvel fans. Online discussions have been filled with theories about the future of the Black Panther mantle and how the Fantastic Four will integrate into the 'Avengers' storyline. Many fans believe the decision to hold back Doom's full reveal may be intentional, designed to maintain suspense and deliver a more impactful moment when the character is officially unveiled.
