The sliding timeline is a funny thing. You can go from being someone’s younger sister to someone’s niece. Introduced in Tales of Suspense #75 (1965) by Stan Lee, Jack Kirby and Dick Ayers, Sharon is the niece of WWII freedom fighter Peggy Carter. Sharon grew up listening to her aunt’s stories of the War and her adventures with Captain America. Her admiration for these stories led her to join SHIELD. Rising quickly through the ranks and earning the codename Agent 13, she was assigned to receive a canister from THEM. However, she was attacked by Batroc and was saved by Cap. After working side by side and revealing who she really was, Sharon and Cap fell in love.

After a brief leadership role with the Femme Fatale, she retired to spend time with Cap. After rescuing her aunt from Dr. Faustus, Sharon was seemingly killed after being brainwash by the doctor. It was later revealed that Nick Fury staged her death to allow her to go deep undercover but because only Fury knew she was alive, when he died, she had no choice but to join with Red Skull. She was rescued by Cap and would investigate Nick’s death only to find out it was also staged. This would lead her to travel back in time to WWII where she confronted Fury. After returning, she would be assigned as Director of SHIELD. She would later return to the field work and was assigned as Cap’s liaison for SHIELD.

She would later come under the control of Faustus, who used his hypnosis to make her assassinate Cap when he was arrested after the Civil War. She would find out she was pregnant with Cap’s child but would be kidnapped by Red Skull, who planned to transfer his mind into the baby. She managed to escape but a fight with Sin saw her being stabbed in the stomach, losing her child. She would be rescued by Falcon and would help in bringing Steve back to life. They would resume their relationship, and both would help set up the Secret Avengers.

After Steve returned to the role of Cap, he was trapped in Dimension Z for what seems like decades. However, Sharon travelled to the dimension and revealed that it had only been a few minutes. They worked together to defeat Arnim Zola but seemingly died for Cap and Jet Black to travel to the Prime universe. Sharon survived and took to raising Steve’s adopted son, Ian, until Arnim Zola traveled to the real world for an invasion. Ian, now Nomad, went to get his father to rescue his mother, who had aged since they last saw her. Steve, now aged because of the Iron Nail, retired but being Cap and continued their relationship. After Pleasant Hill, she was nominated to the Director of SHIELD again but refused the role and nominated Steve. However, this turned out to be a Hydra doppelganger from an alternate universe. After he was defeated, she was reunited with Steve and has since been de-aged.

As one of Cap’s main supporting characters and his main love interest in the comics, Sharon has been requested by fans for years. She would receive a few figures over the years. Her first ML was part of 2-part with Iron Man, though it was a hard-to-find variant set. She would receive another figure as part of the Red Onslaught wave.
