When the animated series What If… ? first dove into the Marvel Cinematic Universe, one of the first character it introduced was Captain Carter. A variant of Peggy Carter from the Captain America franchise, Carter went on to take the super soldier serum instead of Steve Rogers.
Captain Carter made a surprise appearance in live-action in Doctor Strange in the Multiverse of Madness where she was a member of the Illuminati. Her character was the first to make the jump for animation to live-action, so her presence in the Doctor Strange sequel raised many questions. Primarily, fans have wondered if the Captain Carter seen in What If… ? was the same variant in Multiverse of Madness.
Marvel Studios confirmed at their animation panel at San Diego Comic-Con that the two Captain Carters are indeed variants of one another. Importantly, that means that the What If… ? Captain Carter did not die at the hands of the Scarlet Witch. It also means that both the animated and live-action future of What If… ?’s Captain Carter, voiced and played by Hayley Atwell, may be bright.
