A new report suggests that a fan-favorite Marvel character could be stepping into a more prominent role in Avengers: Doomsday. As anticipation builds for the movie, speculation indicates that Peggy Carter may be gearing for her most significant appearance yet in an Avengers film.
Peggy Carter rumored to have her biggest Avengers movie role in Doomsday
Fresh speculation suggests Hayley Atwell could play a significant role in Avengers: Doomsday, potentially making her most substantial appearance yet. According to industry scooper Daniel Richtman, Atwell’s Peggy Carter is expected to feature more prominently than in any of her previous MCU films. However, as of now, Marvel Studios has not officially commented on the claim.
Adding to the speculation, scooper MyTimeToShineHello previously claimed that Atwell could portray multiple versions of Peggy Carter in Avengers: Doomsday. This includes the timeline version introduced at the end of Avengers: Endgame, where Steve Rogers chose to remain with Peggy after returning the Infinity Stones. Another potential appearance involves Captain Carter, the super-soldier variant introduced in What If…? and later seen in Doctor Strange in the Multiverse of Madness.
A recently released teaser trailer has also fueled social media discussion. The trailer shows Steve Rogers living a quiet life with Peggy Carter and their young son following the events of Endgame (via CBR).
The speculation follows earlier report from Deadline in December 2024, which stated that Atwell was set to reprise her role as Agent Carter in Avengers: Doomsday. For now, all details surrounding Peggy Carter’s role remain unconfirmed. Until Marvel Studios offers official clarification, these reports should be treated as speculation.
Avengers: Doomsday is scheduled for release on December 18, 2026, with Anthony and Joe Russo returning to direct after their work on Avengers: Infinity War and Avengers: Endgame. The film will be followed by Avengers: Secret Wars on December 17, 2027.
