Peggy Carter’s great-niece is more than just a Marvel secret agent to the rescue.

Sharon Carter debuted in the Marvel Cinematic Universe as Agent 13 during the events of Captain America: The Winter Soldier.

Many people were already familiar with the actress who played her, Emily VanCamp, thanks to her leading role in the successful ABC drama series, Revenge.

As a highly-trusted S.H.I.E.L.D. agent, Carter was sent on an undercover mission by Nick Fury to keep tabs on Steve Rogers as he established a new life in the present.

She soon had to blow her cover when Fury was attacked and it was revealed that HYDRA had infiltrated S.H.I.E.L.D.

Carter helped thwart the HYDRA uprising, but when S.H.I.E.L.D. disbanded, she joined the CIA to help stop terrorist attacks.

Later, it was revealed that Sharon was the great-niece of Peggy Carter, Steve’s WWII-era crush.

When Steve, Bucky and Sam found themselves on the run during Captain America: Civil War, Sharon came to their aid, and seemingly began a new romance with Steve.

This storyline wasn’t popular with many MCU fans, but Sharon and Steve’s romantic relationship has long been established in the pages of Marvel Comics.

Carter returns in Marvel’s The Falcon and the Winter Soldier when Bucky Barnes and Sam Wilson need some serious help.

The duo would struggle to find a better comrade against the world’s villains than Carter, a trained martial artist with deadly espionage and weapons skills.
