Marvel’s What If has introduced us to countless versions of old heroes, but the series hasn’t been shy about playing favorites: across its three seasons, one particular variant has played a larger role than the rest. Captain Peggy Carter (Hayley Atwell) was the first hero to get a major makeover in What If, going from Captain America’s steely love interest to a super soldier in her own right. Her adventures have brought her beyond the physical plane, face to face with Uatu the Watcher (Jeffrey Wright), and even into live-action with Doctor Strange in the Multiverse of Madness.
Captain Carter is by far the biggest success of What If, as she’s one of the series’ large cast to make the jump to the MCU proper. With Atwell joining the cast of the latest Avengers movie, many assumed that her variant would continue to play a major role in Marvel’s Multiverse Saga. Avengers: Doomsday could do what Doctor Strange couldn’t, and give the character a more worthwhile story in live-action. But as much as she deserves the spotlight, her latest What If appearance is already casting doubt on that theory; in fact, it may have removed her from the multiverse altogether.
