Sharon Carter

"Move away from your station!" "Like he said, Captain's orders." "You picked the wrong side, agent." "Depends on where you're standing."

- Brock Rumlow and Sharon Carter

Sharon Carter is the great niece of legendary S.H.I.E.L.D. founder Peggy Carter. Following in her aunt's footsteps, Carter became an agent of S.H.I.E.L.D. who briefly worked undercover as the neighbour of Steve Rogers under the direct orders of Nick Fury. She fought on the side of S.H.I.E.L.D. during the Battle at the Triskelion, facing off against Brock Rumlow to protect millions of lives. In the aftermath of the HYDRA Uprising she was forced to leave S.H.I.E.L.D. and instead joined the CIA. She continued to have a close relationship with Rogers and sided with him when he chose to protect Bucky Barnes from the government, sparking the Avengers Civil War.

Agent of S.H.I.E.L.D.
The great-niece of S.H.I.E.L.D.'s co-founder Peggy Carter, Sharon grew an interest in the agency, and followed Peggy's advice to join despite her mother's protests to the contrary. To ensure she would not be on her famed ancestor's shadow, Sharon refused to disclose her surname while at S.H.I.E.L.D.

Undercover Mission
"Captain, I'm Agent 13 of S.H.I.E.L.D.'s Special Service. I'm assigned to protect you." "On whose order?" "His."

- Sharon Carter and Steve Rogers

Sharon Carter was assigned by Nick Fury to protect and monitor Steve Rogers in his home apartment and was given the apartment opposite to his, acting as a nurse going by the name Kate. She would report back to Fury to ensure that Rogers was not a threat to S.H.I.E.L.D. and could be trusted. Over her tenure as his protector, Carter became well acquainted with Rogers, and would talk to him whenever they met, often flirting with Rogers in order to gain his trust. One day, Sharon Carter met Steve Rogers outside their respective apartments; after a brief chat, Rogers shyly asked Carter if she wished to join him for coffee, which she politely refused, noting she had to do her laundry. Before she left, Carter informed Rogers that he seemed to have left his radio on as it was still playing music. When Nick Fury was attacked by the Winter Soldier in Rogers' apartment, Carter burst in to aid Rogers, informing him that she was a member of the S.H.I.E.L.D. special service and had been assigned by Fury to protect him. She stayed with Fury providing medical attention while Rogers attempted to apprehend the attacker.

Meeting with Alexander Pierce
"Captain Rogers." "Neighbour."

- Sharon Carter and Steve Rogers

When Fury was declared dead after surgery failed to save him, Carter met with Alexander Pierce inside the Triskelion, who questioned her about the incident and reassured her by saying that she had done everything she could have done to save the Director. As she exited Pierce's office, she passed Rogers who was also on his way to meet with Pierce; as they passed Rogers nodded to her and called her neighbour.

Project Insight
"With all due respect, if S.H.I.E.L.D. is conducting a manhunt for Captain America, we deserve to know why." "Because he lied to us."

- Sharon Carter and Alexander Pierce

When Jasper Sitwell ordered all S.H.I.E.L.D. agents to join the manhunt for Captain America after he escaped the Triskelion, Carter questioned his orders, demanding that if they were going to hunt down Captain America, they should learn why. However, Alexander Pierce arrived and told the staff that Rogers was withholding information from S.H.I.E.L.D. making him a threat.

HYDRA Uprising
Carter was working in the central control room for Project Insight when Captain America revealed the infiltration of HYDRA. Brock Rumlow and STRIKE walked into the control room and Rumlow threatened to kill Cameron Klein, the agent in charge of the launch, unless he began the launch sequence immediately. Klein refused, saying that he would not put the Helicarriers in the air. Rumlow ordered him to step away from his station but Carter then intervened. She pointed her gun at him telling him to stand down; as she did this, the other loyal S.H.I.E.L.D. agents in the room pointed their guns at STRIKE and a gunfight broke out. Rumlow, despite Carter's best efforts, managed to put the Helicarriers in the air.

Working for the CIA
With S.H.I.E.L.D. having been dismantled after the events of the HYDRA Uprising, Sharon Carter was left without employment. Seeking to still have a job which involved helping people, she joined the CIA as an agent given the skills she possessed as a spy. To prove herself as an expert marksman as well, she demonstrated her abilities at a shooting range, scoring top marks with minimal effort.

Peggy Carter's Funeral
"Margaret Carter was known to most as the founder of S.H.I.E.L.D., but I just know her as Aunt Peggy. She had a photograph in her office: Aunt Peggy standing next to . As a kid that was pretty cool. But it was a lot to live up to, which is why I never told anyone we were related."

- Sharon Carter

At Peggy Carter's funeral in London, Carter gave a eulogy for her aunt; while giving the eulogy, Sam Wilson who attended the funeral, noticed Carter and told Steve Rogers, who was also in attendance and realized that Carter was related to his former love. In Carter's eulogy, she explained that she could never live up to her aunt so that was why she never revealed to anyone that they were related to each other.

Arresting Captain America
Carter met up with Steve Rogers, who had noticed her at the funeral, and the two talked for a bit about her work for the CIA. The two were interrupted by Sam Wilson who informed Steve that the International Centre in Vienna had been destroyed. Carter, Rogers, and Wilson all watched the news report saying that the bomb was set by James Barnes. Carter told Rogers and Wilson she had to get back to Berlin and left the two of them behind. While Rogers and Wilson planned to go and find Barnes, Carter met up with them at a cafè and gave them some information about Barnes, including that her CIA team had orders to kill him.

Fighting Winter Soldier
Together with Everett Ross, Carter greeted Steve Rogers, Sam Wilson, Bucky Barnes and T'Challa, who were all brought to the Joint Counter Terrorist Centre. Rogers and Wilson were taken to Tony Stark who informed them of the situation. Carter gave them the receipt for their equipment. When Barnes was being interrogated by Helmut Zemo, Carter disabled the restrictions so Rogers could eavesdrop on the conversation. When the electricity in Berlin went off due to Zemo's e-bomb, Barnes, under the control of Zemo, made his escape. While escaping, Bucky engaged in a fight with Stark, Carter and Natasha Romanoff. Barnes defeated Stark and Carter started to fight him, but got thrown away, smashing into a table.

Aiding Fugitives
While Steve Rogers, Sam Wilson and Bucky Barnes were all being hunted by the government, Rogers called Carter and got her to retrieve their equipment for them. She met up with them in a secret location. Rogers thanked Carter for risking her job for them and the two shared a passionate kiss that Rogers stated was late. After they kissed Carter left and Rogers turned around to find Wilson and Barnes smiling at him.

Sharon is guided by a strong moral compass and is not afraid to speak out when her ethics are challenged.
