Sharon Carter (Marvel Cinematic Universe)

Sharon Carter, alias Agent 13, is a supporting character from 2014 film "Captain America: The Winter Soldier" and 2016 film "Captain America: Civil War.

Sharon Carter was a field agent with S.H.I.E.L.D. who was given a mission to discreetly monitor and protect Steven Rogers at his home when he was off duty. She adopted a cover as a nurse and moved into an adjacent apartment to further her assignment.

The assignment came to an abrupt end one night when she heard gunshots, and crept into Steve apartment to find not only her charge, but also her commanding officer Nick Fury, who had been shot and grievously wounded by sniper fire from a nearby building. Carter called in support and administered first aid, while Rogers left to pursue the shooter.

The incident proved to be part of a sequence of events leading to a coup engineered by hidden elements of Hydra. At first she was alarmed by orders to S.H.I.E.L.D. agents for the capture of Steve Rogers, demanded to Agent Sitwell as to why they were issuing a manhunt. World Security Council secretary Alexander Pierce walked in and claimed that Rogers withheld information about Fury's death.

Later at the Triskelion, she overhears Rogers revealing that Hydra had infiltrated S.H.I.E.L.D. and were planning on using Project Insight to commit mass murder and urged every clean agent to stand up. She bore witness to an armed takeover in an operations room, and while she did her best to prevent Hydra's plans from coming to fruition, a gunfight erupted that gave Hydra the chance to commence a launch sequence for Project Insight.

Carter got through the ordeal of S.H.I.E.L.D.'s subsequent collapse, and turned instead to the Central Intelligence Agency where she could continue to use her skills to best effect.

She is portrayed by Emily VanCamp.
