Peggy Carter

"The world has changed, and none of us can go back. All we can do is our best, and sometimes, the best that we can do, is to start over."

- Peggy Carter

Margaret "Peggy" Carter was one of the most prominent agents of the Strategic Scientific Reserve (SSR) before, during, and after World War II. Originally an officer of the British Armed Forces, at the beginning of the war she joined the Strategic Scientific Reserve (SSR), an Allied deep science agency formed to fight against HYDRA, the Nazi super weapons division. On the undercover mission in Germany she saved Professor Abraham Erskine from the villainous Johann Schmidt. The success of her mission enabled the SSR to start Project Rebirth, an effort to develop the Super Soldier Serum to make an army of Super Soldiers. During the project she met and befriended the frail Steve Rogers, the US Army soldier and one of the project's candidates.

In 1943, after the abrupt end of Project Rebirth and Rogers' transformation into the only Allied Super Soldier, Carter assisted him in becoming the world's first super hero―Captain America, 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 Strategic Scientific Reserve, Carter helped former colleague Howard Stark clear his name when he was accused of being a traitor, and later 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.

Early Life and Military Career
Margaret "Peggy" Carter was born to Harrison and Amanda Carter on Wednesday, April 9, 1919, in London, England. She received her education from.

By 1939, Carter was a member of the British Royal Military. She became an advisor to the Strategic Scientific Reserve.

Joining the Strategic Scientific Reserve
"Take your serum to the Allies, where it can be turned against HYDRA."

- Peggy Carter to Abraham Erskine

Peggy Carter was an agent of the British Secret Intelligence. In November 1940, she infiltrated Castle Kaufmann, the headquarters of the SS general Johann Schmidt, leader of HYDRA, Adolf Hitler's top secret science division. Disguised as a maid Eva, she freed the captured scientist Abraham Erskine, who created the Super Soldier Serum and escaped the castle.

Soon, Carter was assigned as a liaison from the British government to help the Americans combat against the Nazis. Carter served under Colonel Chester Phillips in the Strategic Scientific Reserve.

In the winter of 1942, Carter spent time in the sewers of New York City. Carter also spent time in the Soviet Union, learning local dialect which kept her from freezing to death.

Project Rebirth
"Faster, ladies! Come on! My grandmother has more life in her, God rest her soul. Move it!"

- Peggy Carter

In June 1943, she met Steve Rogers at Colonel Chester Phillips' training base and oversaw his and the other potential candidates' training for Project Rebirth. She smiled each time Rogers would do something smarter or braver than the other candidates, such as dispatching a flagpole to retrieve a flag or diving on a grenade, not knowing it was a dud, to protect others. When Rogers was selected as the candidate, she escorted him to the Strategic Scientific Reserve Brooklyn Facility under an antique shop. After Dr. Abraham Erskine was murdered by Heinz Kruger after Rogers' successful transformation, she followed Rogers and the spy into the streets of Brooklyn and fired several rounds into the car the spy was using to escape.

Colonel Phillips was given a new assignment to take the S.S.R. to Europe to take the fight directly to HYDRA and made Agent Carter and Howard Stark a part of his staff. In November 1943, Agent Carter and Howard Stark helped Captain Rogers get to his destination to the secret HYDRA base in Austria where allied POWs were held. Carter soon developed a crush for Rogers, though referred to it as "having faith in him".

Working with Captain America
Peggy Carter was present at the meeting of the senior staff of Strategic Scientific Reserve in London, along with Colonel Phillips. They discussed the best way to take down HYDRA bases scattered across the Nazi-occupied Europe. Carter became furious at Steve Rogers after she saw him being kissed by Colonel Phillips' secretary Lorraine.

Losing Steve Rogers
"I'll-I'll get Howard on the line. He'll know what to do." "There's not enough time. This thing's moving too fast and it's heading for New York. I gotta put her in the water." "Please don't do this. W-we have time. We can work it out."

- Peggy Carter and Steve Rogers

In May 1945, Carter was a member of a company of soldiers led by Colonel Chester Phillips to follow Captain Rogers into HYDRA's last base of operations. Carter was able to save Captain America's life when he was pinned back by a HYDRA soldier using flame throwers; Carter shot the enemy soldier in the back causing his equipment to explode. Johann Schmidt managed to get to his HYDRA plane and Captain America gave chase; seeing that he had no chance of catching up, Carter and Colonel Phillips stole Johann Schmidt's Coupe and gave Rogers a lift. Moments before he jumped aboard the Valkyrie, Carter kissed Rogers and told him to get Schmidt.

After a brutal fight to the death on a HYDRA plane, Johann Schmidt was finally defeated, along with his soldiers. Knowing that the plane Rogers was on would cause a lot of trouble for America, he was left with one option; forcing the large plane to land on the waters of the Northern Atlantic Ocean. Carter, knowing that this would result in his death, did not give up hope. She pressed on the matter, implying that there would be time for them to sort the situation out, even if Howard Stark had to be called. However, Rogers claimed that there was not enough time, and proceeded with the landing. As the plane made its final descent, Peggy and Steve set a date where she would teach him how to dance. All communications with the plane were then lost, and all Carter could do was cry.

The Obelisk
"These assets are now under the protection of the Strategic Scientific Reserve. They'll be relocated and hidden out of sight, indefinitely, as will you." "Cut off one head, two more shall grow in its place." "Then I guess we'll keep cutting them off."

- Peggy Carter and Werner Reinhardt

Later that year, Peggy Carter led a Strategic Scientific Reserve team that included Jim Morita and Dum Dum Dugan into the last HYDRA base, commanded by General Werner Reinhardt. After arresting him, she had everything in the base confiscated and labelled. The label 0-8-4 was placed on an alien artifact in Reinhardt's possession that was shaped like an Obelisk. Carter discussed with Dugan that, with the war ending, a peace time organization was needed to protect the innocent from dangerous technologies and to supervise people like Howard Stark.

No Deal for the Devil
"It's true, I wanted to find out what kind of a man you were. You didn't use the pen. So, now I know." "Pens are also used for signatures." "You want a deal. How terribly shocking." "The US Government has recruited many German scientists."

- Peggy Carter and Werner Reinhardt

After his capture, Reinhardt was taken to the Rat, a secret SSR facility. Seeking to find out more information, Carter visited the Rat to interrogate him. They talked about the pen that she had left in his cell to find out what he would do with it. As many former Nazi scientists were already recruited by the US Government, Reinhardt expressed the wish to be recruited as well, as he considered himself far more valuable than those who would make parlor tricks by sending rockets into space. Agent Carter then mentioned his many war crimes, but he offered to help her understand the items the SSR has confiscated from his last commanding post. He told her about the myth about the "stars" and revealed that the artifacts were of extraterrestrial origin.

The disdain that Carter had for Reinhardt outweighed her curiosity about the "blue angels" he described so she sentenced him to a life term in the Rat, promising him that as long as she had a say, he would never be freed.

Stark's Problem
"I figured you'd never have a problem finding a man." "The trick is finding the right one."

- Howard Stark and Peggy Carter

Becoming a Double Agent
Following the end of the war, Carter found herself still working for the SSR under the cover of working for a phone company. Having few friends in New York City, she moved in with her friend Colleen O'Brien. Despite her work during the war, many of the men at the office still viewed her as nothing more than Captain America's "liasion". At one meeting, SSR agents discussed Howard Stark being accused of selling his weapons to enemies of the U.S., and though Carter tried to defend Stark based on their past relationship, the other agents rebuffed her. When Agent Ray Krzeminski insulted her, Agent Daniel Sousa came to her defense; Carter thanked him but told him she did not need his help. Later at the L&L Automat, Carter found a note that told her to go into the back alley where Carter met with Stark and his butler Edwin Jarvis. In the car, Stark told Carter he was being framed claiming that someone had stolen his "bad babies", weapons he considered to be too dangerous for anyone to possess, while he was vacationing in Monaco. He told her that he ran because he knew that the SSR would consider him guilty. Stark asked Carter to help him clear his name and find the true criminals behind the theft. As he departed for Europe to track down some of the stolen items, Stark told her to find a document with the formula of one of his inventions, molecular Nitramene, hopefully before it could be sold on the black market.

In searching for the stolen weapons, Carter balanced actively investigating the theft while avoiding SSR scrutiny and other agents looking for the same clues without similar motivations concerning Howard Stark. Carter, disguising herself with a wig and sparkling evening dress, went to a known fence, Spider Raymond, paid to sell the Nitramene formula. Sneaking her way into the office where the formula was being kept, and avoiding SSR agents as she went, Carter discovered that the formula had been used to create a bomb. Racing home, Carter disarmed the weapon, rendering it harmless. Upon entering her bedroom, she found her roommate murdered and was attacked by the killer. Carter fought him off, injuring him in the process, and went to mourn the death of her friend.

Enlisting the aid of Jarvis, Carter followed up a lead concerning the production of the Nitramene weapon based on information from one of Stark's associates, Anton Vanko. Tracking production to the Roxxon Refinery, Carter and Jarvis stumbled upon a whole production line of the weapons. Carter confronted Leet Brannis who told her she could not stop Leviathan before setting one of the Nitramene bombs to go off. He escaped in a milk truck filled with a new batch of the Nitramene bombs while Carter raced back to Jarvis's waiting car. They barely escaped as the bomb went off and the resulting implosion reduced the Roxxon factory to rubble.

Further Investigation
Following the explosion, Carter then went to Howard Stark's Penthouse to rest. The next morning, posing as a health inspector Ruth Barton, she finds the name of the owner of the milk truck, Sheldon McFee. She was then called in to help in discovering who was involved in the explosions besides by using the Vita-Ray Detector.

While scanning Roxxon employees Carter recognized one of the men as a guard she encountred while infiltrating the refinery. Carter then suggested to Roger Dooley that they scan the workers clothes for traces of Vita-Rays the employee then tried to flee only to be easily incapacitated by Carter. While interrogating the employee identified as Miles Van Ert, Dooley allowed Carter to take the rest of the day off.

Carter and Jarvis went to the residence of Sheldon McFee where Carter encountred him and defeated him as she tied him up. Brannis attempted to flee in McFee's milk truck only for Jarvis to disable it. As Carter and Jarvis drove back to Manhattan with Brannis in tow they were attacked by the Man in the green suit again. Carter engaged him on top of the truck and after a brutal fight Carter managed to defeat him and stuck his hand to the truck as she and Jarvis escaped with Brannis while the milk truck which was full with Nitramene safely exploded inside the ocean. Back at Stark's Penthouse Jarvis tended to her wounds and told Carter that despite all her skills she could not handle everything by herself. When Carter argued that Steve Rogers could Jarvis reminded her that Rogers would often rely on her for moral guidence and strength. and asked her to let him help her more, Carter agreed and told him to continue stitching up her wound. Carter then decided to accept the invitation by her friend Angie Martinelli to have an interview at the Griffith Hotel. Martinelli introduced Carter to the other tenants before her interview with Miriam Fry. Carter worked out the sort of women Fry wanted at the hotel and lied about her dependance on men and desire to be married. Pleased with these answers Fry told Carter the rules of the hotel and allowed her to move in next door to Martinelli.

The Heartbreak
Carter and Jarvis investigated the vault where Stark's weapons were stolen but, before they could begin, Thompson and Sousa knocked on the door. The two agents questioned Jarvis and took him in for further interrogation. When Jarvis was brought in for questioning, Carter took the police theft report of Stark's car and later told Dooley that she mistakenly took the report in Jarvis' presence, thus freeing him from his interrogation. After being reprimanded by an angry Dooley she and Jarvis continued their investigation and found the ship that had some of Stark's stolen inventions. Finding the weapons, Carter prepared to call this find in, but Jarvis told her it would be too risky, and he called it in himself as an anonymous tipster. While waiting for Jarvis on The Heartbreak, Peggy was confronted by Jerome Zandow who attacked her. Jarvis came to her aide and together the two managed to subdue him and escape.

The next day Carter found out that Agent Ray Krzeminski had been killed. Deeply saddened by his death, she went to Angie Martinelli and confided in her and told her that despite all of Krzeminski's flaws, he was still a man good at his job.

Betrayal
Carter and Jarvis snuck Howard Stark back into the states through a train car by making a deal with two subordinates of smuggler Otto Mink, the deal went south when one of the men decided they should get paid more, forcing Carter to knock them out and free Stark. Carter attempted to take Stark to his penthouse, but it was being guarded by an SSR agent. Thinking of nowhere else to safely put him Carter snuck Stark into her apartment at the Griffith Hotel. The next day Stark gave Carter a camera pen to take pictures of the devices the SSR had confiscated. Later that day Stark revealed to Carter the reason he came back was because the SSR had one of his most dangerous inventions : The Blitzkrieg Button a device capable of causing a massive blackout and asked Carter to retrieve it and return it to him so he could deactivate it. On the way to the SSR Carter started to get suspicious when she noticed Jarvis nervous behavior. Discovering the device Carter against her better judgement decided to activate it only for the device to open revealing a vial before leaving Thompson confronted her a coldy told her that no matter how hard she tried no man would treat her like an equal.

Returning to the hotel Carter asked Howard what was in the vial and after some reluctance revealed it to be Steve Rogers blood. Angered Carter punched Stark and berated him despite Starks attempt to justify himself Carter accused him of only wanting to make money and decided to cut all ties with him.

One of The Guys
"I am a federal agent, Mr. Jarvis." "Yes. Finely trained and skilled in the art of fetching coffee."

- Peggy Carter and Edwin Jarvis

Carter headed to work when Edwin Jarvis tried to apologize for Howard Stark's lying to her; however, Carter refused to forgive Stark or Jarvis. Jarvis pointed out that the SSR would never treat her like an equal; Carter told him that she will make them change their minds.

At the New York Bell Company Office, the office was busy as Daniel Sousa told Carter that the Remote Typewriter had activated and that they had a decoder working on it. The decoder however proved to be having trouble decoding the message. Carter saw that the original language was Russian and easily decoded it revealing to the others that the message was apparently Leviathan making a deal with Howard Stark for weapons in Belarus.

Chief Roger Dooley quickly told Jack Thompson to prepare a team to go Belarus. Carter insisted that she come along much to Thompson's and Dooley's chagrin. Carter pointed out that she had decoded the message and knew the way of the land in Russia including knowing skills of how to survive in the mountains. Dooley acquiesced however when Carter got them the assistance of the Howling Commandos. In Russia Peggy met up with the Commandos which consisted of her old friend Dum Dum Dugan, Happy Sam Sawyer, Pinky Pinkerton and Junior Juniper. As the two groups rested for the night they shared stories. When Thompson sat down they encouraged him to share one of his war stories. After some reluctance, Thompson told them the story of how he killed Japaneses soldiers that were attacking his unit while they were asleep.

The next day the group arrived at the Red Room Academy where they split up. Carter, Juniper, and Dugan realized that the facility was a school where they encountered a little girl who quickly became hostile, stabbing Dugan and killing Juniper. Carter met up with Thompson's group and together they decided to leave. On their way out they came upon two prisoners named Nikola and Ivchenko. The two had revealed that had been kidnapped because of Nikola's intelligence and Ivchenko's status as a doctor to treat Nikola. They also revealed that Levithan had stolen weapons from Stark. Freeing them, the group was pinned down by reinforcements and Agent Mike Li was shot. When Nikola attempted to bargain Sawyer for his freedom, Li used the last of his strength to shoot him and the group escaped. Parting ways, Carter said goodbye to Dugan and Ivchenko, having nowhere else to go, decided to go back with Carter and the others to use what he knew to help the SSR against Leviathan.

On the plane ride home Carter tried to cheer Thompson up about freezing during the gun fight. Thompson revealed to her that the soldiers who seemingly attacked his unit were actually surrendering and told her that he has been struggling how to tell that story. Carter reassured him that he already did. Back in the U.S. Thompson and Carter reported to Dooley and told him of their findings. Thompson then invited Carter for some drinks.

On the Run
With Ivchenko now with the SSR, Carter, Thompson and Dooley began to question him about Levithan. Carter showed particular interest in Levithan's training of young female assassins, as she believed a female had killed Ray Krzeminski and had possibly seduced Howard Stark to steal his weapons. Dooley ordered her to dig deeper and learn more about the Levithan's female assassins.

Carter called on Edwin Jarvis for assistance again and together they visited many of Stark's former lovers of the last six months to see if they could be an assassin. Carter believed that they would have scarred wrists from being handcuffed to beds their entire lives. In the end there was only one woman named Ida Enke they were unable to locate.

Carter and Jarvis visited the L&L Automat to discuss their next move. While there, Carter realised that many SSR agents had arrived and ordered all civilians to safety. Knowing she was about to be arrested, Carter and Jarvis fought off the agents and tried to escape. Outside they were cornered by Jack Thompson; however Carter was able to disarm him and knock him out. Next, Daniel Sousa tried to arrest her but Carter told him that he would never be able to shoot her; he let her go, promising her that she would be caught. Carter ran back to the Griffith Hotel in order to collect Steve Rogers' blood. She made it to her room but the SSR was quickly behind her. She collected the blood and decided to hide on the ledge outside the building. Thompson and Sousa searched her room. She was spotted by Angie Martinelli; when the agents went into Martinelli's room to question her, she helped Carter escape by distracting the agents. After they left, Martinelli helped Carter into her room and arranged for a car to take out of town. Carter said goodbye to her friend and promise to one day to tell her eveything. With the coast clear, Carter tried to make her escape from the Griffith but was stopped by Dottie Underwood. At first, Underwood seemed concerned for Carter's safety, but when she tried to get past, Underwood grabbed her and kissed her. Carter quickly recognised her own Sweet Dreams Lipstick and began to fall unconcious. Moments before she collapsed, she looked at Underwood's wrist and saw her scars, knowing she was the assassin.

Carter awoke in the SSR's car being driven back to headquarters. She was put in the interrogation room where she began to be questioned by Sousa, Thompson and Dooley.

Interrogation
Roger Dooley, Daniel Sousa, and Jack Thompson took turns interrogating Carter using different methods; Dooley used disappointment, Sousa used friendship, and Thompson hoped that Carter would give them Howard Stark. Carter observed their methodology but none of them seemed to believe what she was trying to tell them.

Zodiac
"Agent Carter, it is my honor to inform you that you are going to run S.H.I.E.L.D. and I'd also like to assist you in carrying your personal items down to your car." "Thank you Agent Flynn, but as has always been the case, I don't require your help."

- John Flynn and Peggy Carter

Agent Carter eventually moved to Brooklyn, New York City continuing to work with the Strategic Scientific Reserve. Carter was stuck in an office run by Agent John Flynn who patronized her and only used her for code-breaking and analysis believing that as a woman, she should not be sent into the field.

Three months into her work there, after all of her fellow agents had gone out for drinks leaving her alone in the office, she received a call directing her to the location of the Zodiac and requesting agents to retrieve the substance.

Carter used the absence of her co-workers as an excuse to take the mission, and traveled to the Zodiac's location, carrying a briefcase full of field gear with her. With some trouble Agent Carter recovered the Zodiac and brought it back to the Strategic Scientific Reserve office. The next day at the office, Agent Flynn admonished Carter for her actions saying that the only reason that she was an agent was that people felt sorry for her after Captain America died. In the midst of his tirade, the office hotline rang and he was informed by Howard Stark that he was to give the news to Agent Carter that she would be running S.H.I.E.L.D.. Stark also ordered Flynn to "let her know you’re honored to bring her the news". Carter refused his offer to carry her things out of the office.

Later Life
"What is it?" "For as long as I can remember, I just wanted to do what was right. I guess I'm not quite sure what that is anymore, and I thought I could throw myself back in, follow orders, serve. It's just not the same." "You were always so dramatic. Look, you saved the world. We rather mucked it up." "You didn't. Knowing you helped found S.H.I.E.L.D. is half the reason I stayed."

- Peggy Carter and Steve Rogers

Peggy Carter continued working for the Strategic Scientific Reserve until 1949. After that, she became a full time S.H.I.E.L.D. Agent, working alongside Howard Stark. Sometime after the war she met and married a man whom Steve Rogers had saved throughout the course of the war. Together they had a son and daughter. In 1953, Peggy Carter was interviewed about Steve Rogers and their involvement in the war. This footage was on display at the Captain America Exhibit at the Smithsonian Institution.

Working with Ant-Man
"Sometime you won't know what you're working with until you're in the moment...so you have to improvise."

- Peggy Carter to Hank Pym

In the 1960s, Carter was still working as a S.H.I.E.L.D. agent. She met Dr. Henry Pym, a young scientist who invented a serum and a suit that could shrink a human being to the size of an ant, yet maintain his original strength. When a group or radicals in the Soviet-controlled East Berlin discovered a piece of an old HYDRA technology, the leaders of S.H.I.E.L.D. decided to send an agent to Germany and stop them from reverse-engineering it.

However, Pym was unwilling to give his suit to anyone else, so Carter convinced him to go to Berlin personally. To see if the suit actually works, she fired a few bullets at Pym, and he became small like an ant in the blink of an eye.

Retirement
"Steve?" "Yeah." "You're alive! You...you came, you came back." "Yeah, Peggy." "It's been so long. So long." "Well, I couldn't leave my best girl. Not when she owes me a dance."

- Peggy Carter and Steve Rogers

Before 2014, Carter had quit S.H.I.E.L.D. and retired. In her advanced age she now has which caused her to have to stay at a retirement home in Washington, D.C..

After Steve Rogers returned from being frozen for nearly 70 years, he was given files about his friends and allies from the 1940's, including Peggy Carter's. He thought about calling her but in the end decided against it, afraid of her seeing him still young.

Two years after he was saved, Rogers eventually went to visit her at the retirement home where she lived. She was lucid at first, but after a few minutes of conversation, due to her mental deterioration, she suddenly acted as if she met Steve directly after he had crash-landed after the Battle in the Valkyrie.
