Marvel fans are buzzing after new reports suggested that Marvel Studios’ Avengers: Doomsday may resurrect two beloved MCU icons. These are Steve Rogers (Chris Evans) and Peggy Carter (Hayley Atwell). Marvel has not officially confirmed their return. However, a trusted scooper shared intriguing details on how these heroes could rejoin the action
Steve Rogers & Peggy Carter’s Pivotal Role in Avengers: Doomsday
Insider sources claim that Steve and Peggy leave retirement to help the Avengers, X-Men, and Fantastic Four. Moreover, they join forces to face the menacing Doctor Doom (Robert Downey Jr.). As a result, this points to a substantial story arc rather than a brief cameo. Ultimately, the theme makes it clear — “a hero’s job is never done.”
If true, this would mark the first time Chris Evans has stepped back into the MCU since Avengers: Endgame. Furthermore, it would also be the first instance of Peggy Carter joining a live-action Avengers crossover — a moment that, unsurprisingly, many fans never thought possible.
Casting Secrets and Avengers: Doomsday Ensemble
Reports suggest that Evans and Atwell quietly joined the cast in December 2024. However, their names were noticeably absent from Marvel’s massive March 2025 casting livestream, which revealed 27 other actors. Consequently, this secrecy has only fueled further speculation about the scale of their involvement. In addition, fans have been eagerly analyzing every casting update for potential hints.
The confirmed cast is already a powerhouse lineup. Returning MCU veterans include Chris Hemsworth, Anthony Mackie, Sebastian Stan, Paul Rudd, and Letitia Wright. Newer stars like Vanessa Kirby, Tenoch Huerta Mejía, Ebon Moss-Bachrach, Simu Liu, and Lewis Pullman will also join the cast.
Six X-Men legends — Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden — return to the franchise, and Channing Tatum makes his long-awaited debut as Gambit.
Which Versions of Steve Rogers and Peggy Carter Could Appear?
Steve Rogers was last seen in Endgame, choosing to live out his days in the past with Peggy. This means the Steve we meet in Avengers: Doomsday could be an older but still capable fighter, possibly mirroring his comic book “Elder Captain America” persona.
Peggy Carter, on the other hand, has appeared across multiple variants — including the fan-favorite Captain Carter in both live-action and animation. Her latest appearance in What If…? Season 3 proved she remains a character with limitless storytelling potential.
Production, Release Date, and Story Scope
Directed by the Russo Brothers (Joe & Anthony), Avengers: Doomsday is set to hit theaters on December 18, 2026, as part of Phase 6 of the MCU. The story promises an epic, universe-spanning battle where Earth’s mightiest heroes unite with mutants and Marvel’s first family to face the threat of total annihilation.
If these rumors pan out, the film will not only deliver jaw-dropping action but also emotional reunions that tap into the MCU’s rich history — making it one of the most anticipated ensemble blockbusters of all time.
