Dr. Margaret Elizabeth "Peggy" Carter, Ph.D., also known as Captain Carter, is the deuteragonist of the Disney+ animated series What If...?. She is a variant of Peggy Carter who took the Super Soldier serum instead of Steve Rogers, becoming a superhero to fight HYDRA. She would sent to the twenty-first century, where she became an agent of S.H.I.E.L.D. and was later recruited into the Guardians of the Multiverse to stop Infinity Ultron from conquering the multiverse.

Like her Earth-199999 counterpart, she is voiced by Hayley Atwell, who also played her Earth-838 counterpart in Doctor Strange in the Multiverse of Madness.
