Agent Peggy Carter, born in England, was a member of the British Royal Military before joining MI6 and then going on to join the Strategic Scientific Reserve under Colonel Chester Phillips. She is highly intelligent, with a knack for code-breaking, and is an expert in espionage. Her training has also made her a crack shot and a powerful hand-to-hand combatant. She was also assigned to infiltrate early HYDRA research facilities and retrieve Dr. Erskine.

In 1943, Cater was one of the agents assigned to Project: Rebirth to help Dr. Erskine choose the right candidate for the experiment. During this period, she met Steve Rogers, a young, frail man that she began to develop feelings for. Soon after, he was given Erskine's super soldier serum, and became Captain America. During a later encounter, she encouraged him to become more than the U.S. Army's mascot, and helped push him into the position of power that he's in now. Due to a misunderstanding, Carter ended up giving Steve the cold shoulder for much of the war, but warmed up again in the final stretch.

When Captain Rogers was lost in the ice, Carter continued to help the S.S.R., joining the Howling Commandos in raids and interrogations, and once the war was over she found a desk job with the agency in New York. She used her position to leverage help for Howard Stark when he was framed for putting out his weapons on the black market.

Peggy Carter is an incredibly strong-willed individual, but this strength is also one of her greatest weaknesses: she constantly takes on challenges alone that would be far better be served with a team, and is extremely determined to overcome the adversity she faces due to her gender—to the point that she can sometimes go overboard. This pride can lead her to take action that most wouldn't, including threats (that she could more than likely execute if she wanted to) and some violence.

Later in life, she helped Howard found S.H.I.E.L.D., and remained active in some capacity well into old age.

EDIT: I forgot to mention that Infiltrator is a custom Edge that I came up with, particularly for these folks in the MCU with all their spies and shit.

Infiltrator
Requirements: Novice, Smarts d6+, Knowledge (Espionage) d6+, Notice d6+, Persuasion d8+, Streetwise d6+
Infiltrators specialize in going undercover, or otherwise assuming a new identity. They are normally trained by government agencies, or perhaps simply have a natural predisposition for lying. Infiltrators add +2 to all Persuasion and Streetwise rolls made to lie or otherwise deceive those around them, including maintaining a disguise or cover.
Note that this is a direct bonus to the Persuasion skill and not additional Charisma, meaning that it applies to rolls made against lie detectors (which generally ignore Charisma modifiers).

This may prove as a useful Edge for any other Super Spy characters out there, though the numbers are still prone to being tweaked down the line.
