Warning: This article contains spoilers for What If...? episode 9.
In Marvel's What If...? finale, Captain Carter fights to save the Multiverse and may also have shown she's worthy of wielding Mjolnir before her return in Doctor Strange 2. The What If...? season 1 finale shook up the Marvel Cinematic Universe. In the final episode, the Watcher (Jeffrey Wright) gathered the various superhero variants revealed throughout the season, and he brought them together to take on Ultron (Ross Marquand). The final team consisted of Captain Carter (Hayley Atwell), T'Challa's Star-Lord (Chadwick Boseman), Gamora (Cynthia McWilliams), Killmonger (Michael B. Jordan), Party Thor (Chris Hemsworth), and evil Doctor Strange (Benedict Cumberbatch). Black Widow (Lake Bell) eventually joined as well. Together, the heroes separated Ultron from the Infinity Stones and saved the Multiverse.
Peggy Carter had a drastically different story in What If...? as opposed to the main MCU timeline. Though, her story in Doctor Strange 2 is yet to be uncovered. In What If...? episode 1, Marvel changes the events of Captain America: The First Avenger. Instead of Steve Rogers (voiced by Josh Keaton) receiving the Super Soldier Serum, Peggy Carter does. She soon takes the name Captain Carter and puts the war effort into her own hands. On the other hand, Rogers becomes the first Iron Man, and the pair take on Hydra together. Unfortunately, it didn't last. They are eventually separated when Carter fights a monster summoned by Hydra back through a portal. She disappears for years.
