The essentials in 30 seconds: Peggy Carter begins as an elite spy during World War II, becomes the co-founder of SHIELD, and embodies one of the most respected figures in the Marvel universe. In the multiverse explored by the animated series What If...?, an alternate version of her receives the super-soldier serum and becomes Captain Carter, a hero in her own right wielding the vibranium shield. A complete look back at her journey, her missions with the SSR, the birth of SHIELD, and this variant who won over fans.
Long before Steve Rogers became the symbol of the Avengers, a woman was already fighting in the shadows to change the course of the war. Margaret "Peggy" Carter never carried the star-spangled shield in the main MCU continuity, yet her influence far surpasses that of many costumed superheroes. A British intelligence officer, SSR (Strategic Scientific Reserve) agent, and later co-founder of SHIELD, Peggy Carter is living proof that one can make history in the Avengers universe without superpowers.
But the Marvel universe never stops at a single version of events. Thanks to the multiverse, an alternate reality gave Peggy Carter what destiny had denied her in the main timeline: the super-soldier serum. As a result, Captain Carter was born, shield in hand and ready to defend her world. In this article, we trace Peggy's entire journey, from her beginnings at the SSR to her heroic alternate version, including the founding of one of the most powerful organizations in the Marvel universe.
Who Is Peggy Carter? The Origins of an Exceptional Spy
Margaret Elizabeth Carter is born in England and joins the British intelligence services at a very young age during World War II. Her discipline, composure, and tactical sense quickly propel her within the SSR, the secret American agency tasked with countering the scientific advances of HYDRA, the Nazi paramilitary branch led by Johann Schmidt, also known as Red Skull.
It is in this context that Peggy crosses paths with Doctor Abraham Erskine and his Rebirth project—the very one that will transform a frail young man from Brooklyn into Captain America. Far from being a mere observer, Peggy actively oversees the trials, trains recruits, and commands respect in a military world largely dominated by men. Her reputation as a formidable and incorruptible agent follows her across every European theater of operations.
A Strategic Ally for the Howling Commandos
Once Steve Rogers is transformed, Peggy becomes a key figure in coordinating the operations of the Howling Commandos, the elite unit that hunts down HYDRA's secret bases across Europe. She handles intelligence, plans infiltrations, and never hesitates to go into the field when the situation demands it. This combination of tactical skill and physical courage makes her a figure feared by the enemy as much as she is respected by her peers.

View productPeggy Carter and Steve Rogers: A Story Suspended in Time
The relationship between Peggy Carter and Steve Rogers is one of the most moving threads in the MCU. Partners from their very first missions, the two characters develop a rare chemistry built on mutual trust and professional respect that gradually gives way to deeper feelings. But war leaves little room for peaceful love stories.
When Steve Rogers sacrifices his freedom by crashing the Red Skull's plane into the Arctic ice, Peggy loses not only a valuable ally but also the man she loved. Yet she continues on her path with unwavering determination, refusing to let grief dictate the course of her career. It is this resilience that leads her to the next stage of her life: building a new agency capable of protecting the world from the threats to come.
Decades later, fate would still offer them one final chapter, when an aging Steve Rogers chose to return to the past to live the life they had never been able to have together, thus closing a particularly touching time loop for longtime fans.
The founding of SHIELD: Peggy Carter's second wind
After the war, Peggy Carter refuses to settle for a secondary role. Alongside Howard Stark and other former SSR members, she actively participates in the creation of SHIELD, the agency that will become the backbone of global security in the Marvel universe. Her vision: an organization capable of anticipating extraordinary threats in a world that has just discovered the existence of super-soldiers, alien artifacts, and technologies capable of overthrowing entire governments.
A Pioneer in a Man's World
Peggy Carter rises through the intelligence ranks at a time when women were systematically excluded from positions of power. She must constantly prove her worth, outmaneuver the schemes of jealous colleagues, and face the skepticism of her superiors. This tenacity makes her a timeless role model, long before the term "empowerment" became popular in popular culture. Her career would directly influence the structure of SHIELD, later led by figures such as Nick Fury, who would inherit her methods and high standards.
It is also this agency she built that, much later, would establish the Avengers Initiative, bringing together scattered heroes to form Earth's first great superhero team. Without Peggy Carter, there probably never would have been Avengers as we know them.

View productCaptain Carter: When the Serum Changes Its Recipient in the Multiverse
It is in the animated series What If...? that the general public discovers Captain Carter for the first time. The premise is simple but fascinating: what if, at the crucial moment of Doctor Erskine's experiment, it had been Peggy Carter who received the super-soldier serum instead of Steve Rogers? This divergence creates a new branch of the multiverse, an alternate Earth where Peggy herself becomes the super-soldier the world was waiting for.
Equipped with a vibranium shield bearing the British flag, Captain Carter fights HYDRA with the same determination as in her original timeline, but this time with superhuman strength and endurance worthy of the greatest heroes in the MCU. She becomes a direct inspiration for what would later become the Zola-verse, as the HYDRA organization survives far longer in this reality thanks to the persistence of Doctor Zola's consciousness.
The central role of the TVA and the multiverse
This alternate version of Peggy Carter exists only because of the mechanics of the multiverse, a concept explored in depth by the TVA (Time Variance Authority), tasked with monitoring divergent timelines. Captain Carter is thus the most iconic proof that every decision and every pivotal moment can generate an entirely different reality in which the heroes we think we know take on unexpected roles.
Her selflessness, loyalty, and sense of sacrifice remain unchanged regardless of which version of the timeline is explored, proving that Peggy Carter is intrinsically heroic, with or without superpowers.
Peggy Carter versus her variants: a comparison table
| Version | Status | Powers | Main role |
|---|---|---|---|
| Peggy Carter (main timeline) | SSR agent and later SHIELD co-founder | None, human excellence | Strategist and institution builder |
| Captain Carter (What If...?) | Super-soldier of the multiverse | Superhuman strength, speed, and endurance | Fighting heroine facing HYDRA |
| Elderly Peggy (main timeline) | Retired SHIELD director | None | Mentor and historical figure |
A close connection with Bucky Barnes and the legacy of World War II
Peggy Carter does not work alone during the war. She regularly crosses paths with Bucky Barnes, Steve Rogers's best friend, during operations carried out by the Howling Commandos. This close connection further strengthens the web of relationships linking the Avengers' origins, where every character—even those who were secondary at the time—would play a decisive role in the organization's future.
This period of war, often summarized in the MCU phases as a simple starting point, is actually the foundation on which the entire Avengers narrative is built. Without the SSR, Peggy Carter, and this generation of heroes operating in the shadows, there would be no SHIELD, no Avengers Initiative, and no coordinated response to the cosmic threats that would follow.

View productWhy Peggy Carter remains an everlasting icon
What sets Peggy Carter apart from most MCU characters is that she never needed superpowers to make her mark on history. Her influence can be felt in every corner of the Avengers universe: in SHIELD's structure, in the respect Captain America inspires, and in the way subsequent generations of agents and heroes were trained. Even her alternate version, Captain Carter, merely confirms what we already knew: Peggy's courage and loyalty transcend timelines.
She also represents a major cultural evolution within the MCU, at a time when superhero stories were beginning to embrace strong, complex female figures who were independent of the men around them. This shift can also be seen in the portrayal of other multiverse characters, where individual origins and decisions completely redefine the fate of the Earth in question—a theme central to stories exploring the chaos of the Marvel multiverse.
