15 Best Supporting Characters In MCU Movies So Far
2. Peggy Carter
Peggy Carter may have only played a major role in one MCU movie, but she never strayed far from the minds of fans after serving as the single most powerful driving force behind Captain America's entire narrative arc for close to a decade.
While The First Avenger was the first and last time we really got to see the capable, determined soldier that she was in her prime on the big screen, the majority of Peggy's further appearances were usually closely linked to Steve Rogers, with the exception of Ant-Man's prologue, which still managed to add more layers to the character by establishing her as a founding member of S.H.I.E.L.D.
Peggy was a force to be reckoned with in her own right, and proved to be so popular that she was also made the star of a Marvel One-Shot and a TV show that ran for two seasons, and even featured in the last shot of the Infinity Saga as her story with Steve finally got a happy ending.
