Hayley Atwell’s Peggy Carter has been a recurring character in the MCU since her debut in Captain America: The First Avenger, with appearances in various films and her own series, Agent Carter. Atwell expressed her desire for Carter to return, emphasizing that the character is “underserved” and has much more potential, especially as she aligns with modern themes. She is eager for the opportunity to further develop Peggy, particularly in upcoming projects like Avengers: Doomsday (2026) and Avengers: Secret Wars (2027).
