History:
Margaret Elizabeth "Peggy" Carter was one of the most prominent agents of the Strategic Scientific Reserve during and after World War II and one of the founders of S.H.I.E.L.D.. Originally a code-breaker working at Bletchley Park, she joined the Special Operations Executive following her brother's death. Carter later joined the SSR, formed to fight HYDRA. On the mission in Germany she saved Abraham Erskine from Johann Schmidt. The success of her mission enabled the SSR to start Project Rebirth and develop their Super Soldier Serum to make the army of Super Soldiers. During the project she had befriended Steve Rogers, one of the project's candidates. In 1943, after the abrupt end of Project Rebirth and Rogers' transformation into the only Super Soldier, Carter assisted him in becoming the world's first superhero, and eventually fell in love with him. After Rogers' disappearance in 1945, she continued the SSR's fight against HYDRA, capturing the last high-ranking HYDRA officer Werner Reinhardt, and continuing her service in the SSR once the War ended. As an agent of the SSR, Carter helped former colleague Howard Stark clear his name when he was accused of being a traitor, and later traveled to Los Angeles where she clashed with Whitney Frost over the extradimensional Zero Matter. She helped Stark found the new peacekeeping organization, the Strategic Homeland Intervention, Enforcement and Logistics Division, better known by its acronym S.H.I.E.L.D. She eventually married a former Allied soldier and became a mother of two children, though she would continue her service in S.H.I.E.L.D. during the turbulent years of the Cold War. Eventually Carter retired and saw her niece Sharon Carter follow in her footsteps. During her retirement, Carter learned that Rogers had survived all these years, but by this time she had been diagnosed with Alzheimer's disease and struggled to take in the news. She died peacefully in her sleep in 2016.

Powers:
 Carter was able to infiltrate Castle Kaufmann and free Abraham Erskine with her disguise as "Eva". Likewise, she was able to flawlessly mimic other accents. She knew how to manipulate the sexist stereotypes of her time to her advantage by bringing coffee to a meeting in order to spy on it and seducing a man to gain information. She also spent time at Bletchley Park during the early years of World War II, learning code breaking skills.  Carter was able to solve the Leviathan case very efficiently, including deducing that the person who manipulated Stark would be one of the women he had been with, and that that woman would likely have scars on her wrists from years of handcuffing herself to a bedpost. In a lot of cases Carter was able to connect evidence or spot things that her colleagues missed.  Carter was a highly skilled martial artist. Carter used her fighting skills to defeat Sasha Demidov before he could kill her. She was able to defeat several highly skilled agents with little effort. Despite initially being overwhelmed, Carter managed to defeat Dottie Underwood, a highly trained Red Room assassin. Carter was also able to silently subdue the guards of the Zodiac. Carter used a direct and highly versatile fighting style; she was adept at constantly using her surroundings to her advantage. Carter was able to quickly use the weapons or clothing of her opponents against them. Highly opportunistic and able to improvise quickly, Carter could use nearly every item available to her as an improvised weapon.  During the assassination of Abraham Erskine, Carter was able to kill the driver of Heinz Kruger, as he drove towards her, without fear of being hit. She chided Rogers for interrupting her shot when she aimed for Kruger. While trying to obtain Zodiac, Carter shot at a steel door multiple times hitting the same spot to create a hole large enough for the gas grenade she had planned to drop.  Though they were all seasoned war veterans, the Howling Commandos took instruction from Carter on how to infiltrate the Red Room Academy, following her leadership on how to divide the men and what to do in a given situation. Though both leaders of their respective branches of the SSR, Thompson and Sousa referred to Carter's plan to fight Whitney Frost.  Carter had knowledge of chemistry, knowing how to use simple household items to create a compound necessary to defuse a bomb.  Carter was able to pickpocket an access card from an employee of Isodyne Energy with ease; however, she was not successful in using her Brooch Key to access Daniel Sousa's desk because he was too close to her.  Carter could speak and read English, Russian and German fluently.
