Marvel's Agent Carter

Part 1: The Dossier: An At-a-Glance Summary

Part 2: Origin and Evolution

Publication History and Creation

Peggy Carter made her first appearance in the comics in Tales of Suspense #77, published in May 1966. She was created by writer Stan Lee and artist Jack Kirby. Critically, she was introduced not in a contemporary story, but in a flashback sequence detailing Captain America's exploits during World War II. Her creation served a specific narrative purpose: to give Steve Rogers a lost love, a tragic romantic figure from his past that would deepen his “man out of time” pathos. In these early appearances, she was not even given a name, referred to simply as a beautiful and capable agent Captain America worked with in the French Resistance. It was only later that she was named Peggy. For decades, her character remained a relatively minor footnote in Captain America's history, primarily defined by her relationship with him and a subsequent, prolonged bout of amnesia. Her true ascension to iconic status began with her portrayal by actress Hayley Atwell in the 2011 film Captain America: The First Avenger. The on-screen chemistry between Atwell and Chris Evans, combined with a script that presented Carter as a competent, formidable character in her own right, resonated powerfully with audiences. This popularity led to the Marvel One-Shot Agent Carter, which directly spawned the ABC television series of the same name. This massive expansion of her character in the MCU retroactively boosted her significance across all media, leading to new comic book series and alternate reality versions, most notably Captain Carter.

In-Universe Origin Story

The origin of Peggy Carter differs significantly in its scope and detail between the primary comic continuity and the massively expanded narrative of the MCU.

Earth-616 (Prime Comic Universe)

Margaret “Peggy” Carter was born into a wealthy family in Richmond, Virginia. As a teenager, she was filled with a sense of adventure and a fierce spirit, inspired by the heroic tales her grandmother told her. When World War II erupted in Europe, she was determined to contribute to the war effort. She left her comfortable life behind and joined the French Resistance, becoming one of its most effective and celebrated freedom fighters. It was during her time in France that she first met and fell in love with Captain America. They worked together on numerous missions, fighting against hydra and the forces of the red_skull. Peggy proved herself to be an expert marksman and a brilliant field agent, earning Captain America's respect and affection. Their romance was intense but tragically cut short. Near the end of the war, an exploding shell knocked her unconscious, and the shock of the event, combined with the subsequent news of Captain America's supposed death in the North Atlantic, triggered a profound case of amnesia. She was found wandering the streets of Paris with no memory of her identity. She was eventually returned to her family in Virginia, where she lived for years in a state of quiet confusion, haunted by fragmented memories of a lost love she couldn't name. Her story was largely one of tragedy and loss, a character defined by what was taken from her. Much later, after Captain America's return, she would eventually regain her memories and join S.H.I.E.L.D. for a time, but her most formative years were spent in a fog of amnesia, a stark contrast to her MCU counterpart. Her niece, Sharon Carter (Agent 13), would later follow in her footsteps and also become a love interest for Steve Rogers.

Marvel Cinematic Universe (MCU)

In the MCU (designated as Earth-199999), Peggy Carter's origin is far more detailed and central to the universe's history. Born in London, England in 1921, Peggy's older brother, Michael, encouraged her to be independent and find her own path, which led her to join the British military. A gifted codebreaker at bletchley_park, her talents were recognized, and she was recruited into the Special Operations Executive (SOE) and later the American-led Strategic Scientific Reserve (SSR), the precursor to S.H.I.E.L.D. She was a supervising agent for Project Rebirth, the program that created Captain America. From the very beginning, she saw the potential in Steve Rogers, not because of his physique, but because of his character and courage. She was one of the few who believed in the “skinny kid from Brooklyn” before he ever held the shield. Throughout World War II, she was Captain America's primary mission handler, strategic partner, and romantic interest. She was not a damsel in distress but a highly trained soldier and spy who fought alongside him, leading the howling_commandos on missions and proving herself to be one of the SSR's most capable assets. After Steve Rogers was lost in the ice, Peggy, along with howard_stark, continued the fight against HYDRA's remnants. The post-war era, as detailed in the Agent Carter television series, saw her facing a new enemy: the pervasive sexism of the 1940s American workplace. Despite her impeccable war record, she was relegated to administrative duties at the New York SSR office, treated as little more than a secretary. The series follows her as she secretly works with Howard Stark's butler, edwin_jarvis, to clear Stark's name when he is framed for treason. In these missions, she combats threats like the Soviet espionage agency leviathan and scientific geniuses like Whitney Frost, all while outsmarting her dismissive male colleagues. Her career culminated in her co-founding S.H.I.E.L.D. with Howard Stark and other SSR allies, becoming one of its most influential leaders, known as Director Carter. She lived a long and full life, eventually marrying an Allied soldier whom Steve Rogers had saved (though her final dance was ultimately with Steve, thanks to time travel in Avengers: Endgame) and passing away peacefully in her sleep at the age of 95, having shaped the world's premier intelligence agency from the ground up.

Part 3: Abilities, Equipment & Personality

Earth-616 (Prime Comic Universe)

Peggy Carter's abilities in the mainstream comics are those of a highly trained but non-powered human. Her portrayal is more limited due to her relatively few modern-day appearances where she is in her prime.

Her personality is defined by courage and a deep capacity for love. However, much of her character arc is tinged with the tragedy of her memory loss and the pain of believing her love was dead.

Marvel Cinematic Universe (MCU)

The MCU's Peggy Carter is one of the most skilled secret agents in the world, with a much more fleshed-out and diverse skill set.

Part 5: Iconic Events & Storylines

Captain America: The First Avenger

This film is the cornerstone of Peggy Carter's modern identity. Her entire MCU arc begins here. She is introduced not as a side character, but as a formidable officer in the SSR who immediately challenges Steve Rogers. Her key role was in selecting Steve for Project Rebirth based on his character, not his brawn. She trained him, fought alongside him, and fell in love with him. The climax of their story in this film is their final, heartbreaking radio conversation as Steve crashes the Valkyrie into the ice. Their promise for a dance becomes the single most powerful unresolved thread in Captain America's story for nearly a decade of films.

The //Agent Carter// Television Series

This two-season series is the definitive deep dive into Peggy's character. Set after The First Avenger, it explores her struggle for relevance and respect in a misogynistic post-war world.

Captain America: The Winter Soldier & Endgame

These films bookend Peggy's life in the original MCU timeline. In The Winter Soldier, a modern-day Steve Rogers visits an elderly Peggy, who is suffering from Alzheimer's disease. The scene is emotionally devastating, showcasing the depth of their bond and the tragedy of Steve's displacement in time. She recognizes him, telling him, “The world has changed, and none of us can go back… you have to start over.” In Avengers: Endgame, Steve Rogers makes the decision to go back. After returning the Infinity Stones, he travels back to the 1940s to live out his life with Peggy. The film's final shot is of them finally having their dance, a quiet, deeply satisfying conclusion to their epic love story and a direct answer to the question, “Who did Peggy Carter marry?”.

Part 6: Variants and Alternative Versions

Captain Carter (MCU - Earth-82111)

Perhaps the most popular alternate version of Peggy Carter, this variant was introduced in the animated series What If…?. In her timeline, Peggy chose to stay on the observation floor during Project Rebirth. When a HYDRA agent attacks and injures Steve Rogers, Peggy steps into the machine herself, emerging as Captain Carter, a super-soldier with abilities equal to Captain America. Wielding a vibranium shield emblazoned with the Union Jack, she becomes the Allies' champion.

Captain Carter (Comics - Earth-86315)

Following the immense popularity of the MCU's Captain Carter, Marvel Comics introduced their own version in a 2022 limited series. This version of Peggy Carter also became a super-soldier, but her story diverges. After the war, she was frozen in ice much like Steve Rogers, only to be thawed out in modern-day Britain. She finds herself working for S.T.R.I.K.E. (the British equivalent of S.H.I.E.L.D.) and struggling to adapt to a nation that she feels has lost its way, dealing with modern political intrigue and threats.

Marvel's Avengers (Video Game)

In the continuity of the 2020 video game Marvel's Avengers, Peggy Carter's legacy as a founder of S.H.I.E.L.D. is a central part of the backstory. She is mentioned frequently in collectibles and dialogue, cited as a hero and an inspiration to the modern generation of agents and heroes.

Notes and Trivia

1) 2) 3) 4) 5) 6)

1)
Peggy was originally intended to be a one-off character in The First Avenger, but Hayley Atwell's performance was so well-received by audiences and producers that her role was significantly expanded.
2)
The Marvel One-Shot Agent Carter, included on the Iron Man 3 Blu-ray, served as a proof-of-concept for the television series. It depicts Peggy retrieving the “Zodiac” serum, a mission that proves her skills and leads to Howard Stark asking her to co-run S.H.I.E.L.D.
3)
In the comics, Peggy's niece Sharon Carter becomes Captain America's primary modern-day love interest, creating a complicated romantic lineage. The MCU simplified this by having Peggy be Sharon's great-aunt instead of her sister.
4)
The question of who Peggy married in the original, unaltered MCU timeline is a topic of much fan debate. Captain America: The Winter Soldier co-director Joe Russo has stated that she married a soldier Steve Rogers saved during WWII, but this has never been explicitly confirmed on-screen. Avengers: Endgame provided a definitive answer for the new timeline created by Steve's return.
5)
Hayley Atwell has voiced Peggy Carter in multiple animated series, including Avengers Assemble and Marvel's What If…?, in addition to her live-action portrayal, making her the definitive actress for the character across the multiverse.
