Sharon Carter

Sharon Carter (also known as Agent 13) is a fictional character appearing in American comic books published by Marvel Comics. She is usually depicted as a secret agent, an ex-field agent of S.H.I.E.L.D. under Nick Fury, and a love interest of Steve Rogers / Captain America.

In the original comic book continuity, Sharon was the younger sister of Peggy Carter, the possible wartime love interest of Captain America. She was later retconned as Peggy's grand-niece because of the unaging nature of comic book characters.

Emily VanCamp portrays the character in the Marvel Cinematic Universe films Captain America: The Winter Soldier (2014) and Captain America: Civil War (2016), and returned to play the character in the Disney+ series The Falcon and the Winter Soldier (2021). VanCamp also voices alternate versions of Carter in the animated series What If...? (2021).
