Marvel Studios may have planned a slow burn for Avengers: Doomsday, but the internet appears to have other ideas. A reportedly leaked teaser has ignited widespread speculation, with fans dissecting every frame for clues. Chris Evans’ Steve Rogers at the center of the storm. Of course, many believed that he had closed his chapter in Avengers: Endgame; however, it appears that the MCU is bringing the fan-favorite character back in action. Add whispers of Peggy Carter’s presence and a cryptic tease from the Russo Brothers, and the MCU’s next event film has already become a cultural flashpoint.
Will Hayley Atwell’s Peggy Carter Return Alongside Chris Evans’ Steve Rogers?

The most talked-about detail from the leaked footage revolves around Steve Rogers, portrayed by Chris Evans. According to reports circulating across social media, the teaser opens quietly. Rogers rides a bike through what appears to be a distant past, steps into a modest house. The emotional beat lands when he is seen holding a baby, with fleeting images that also feature Hayley Atwell’s Peggy Carter.

The clip allegedly ends with the words, “Steve Rogers will return in Avengers: Doomsday.” If authentic, that single line reframes everything fans assumed about Rogers’ ending. Avengers: Endgame left him in an alternate timeline, choosing a life with Peggy Carter rather than the battlefield. This leaked teaser seems to lean into that decision, suggesting Steve’s story continued off-screen.
The idea also clashes with Evans’ repeated insistence that he is “happily retired.” Longtime MCU followers recognize the pattern. Actors often deny involvement until Marvel chooses the moment. However, nothing is officially confirmed as of yet.
Leaked Trailer Teases Insane Details About MCU’s Highly Anticipated Avengers: Doomsday

Reports claim Marvel prepared four short previews, designed for theaters only, attached to Avatar: Fire and Ash. Each teaser reportedly highlights a major player in Avengers: Doomsday. The first centers on Steve Rogers. The second shifts focus to Thor, played by Chris Hemsworth, shown alone in the woods, praying to Odin before a dangerous mission.
The third teaser reportedly introduces Victor von Doom. Robert Downey Jr.’s return to the MCU, this time as Doctor Doom, remains one of the boldest casting choices Marvel has made. After Tony Stark’s farewell in Endgame, Downey’s presence as a villain extends expectations for Phase 6.
Marvel’s aggressive copyright takedowns have only intensified belief in the leak’s authenticity. Fake trailers often linger online. These clips vanished quickly. A ratings board listing for an 85-second teaser further supports claims that official footage exists. Avengers: Doomsday now stands as a massive crossover event, reportedly uniting Avengers, Fantastic Four, X-Men legacy characters, and more against Doctor Doom.

Adding fuel to the fire, the Russo Brothers shared a cryptic Instagram image that fans immediately began decoding. The post shows a blurry black-and-white shape resembling a “V.” Some point to Victor von Doom. Others see the Roman numeral five, aligning with Avengers: Doomsday as the fifth Avengers film.
With Marvel remaining silent, speculation has filled the void. Between leaked teasers, cryptic posts, and long-denied returns, Avengers: Doomsday has already achieved what Marvel does best.
Avengers: Doomsday is scheduled for a December 18, 2026, release.
