Sharon Carter

Sharon Carter is the great-niece of legendary S.H.I.E.L.D. founder and Director Peggy Carter. Following in her aunt's footsteps, Carter became an agent of S.H.I.E.L.D., although she never revealed her relation, not wanting to be put under the pressure of living up to any expectations.

Under direct orders from Nicholas Fury, Carter was tasked with going undercover as a nurse, living next to Steve Rogers. When Fury was attacked, she blew her cover to Rogers. After HYDRA was revealed to have been operating within S.H.I.E.L.D., Carter chose to stay loyal to her organization, and fought during the Battle at the Triskelion, facing off against Brock Rumlow to protect millions of lives.

In the aftermath of the HYDRA Uprising, Carter left the disbanded S.H.I.E.L.D. and joined the CIA, before being stationed at the Joint Counter Terrorist Centre. In 2016, her aunt passed away, and Carter gave Peggy's eulogy at the funeral, where she revealed her true identity to Rogers. When the Vienna International Centre was bombed, Carter returned to the JCTC after giving Rogers information on Bucky Barnes. When Barnes was arrested and brought into the JCTC, Helmut Zemo reactivated his mental programming, causing Carter to try and stop him, to no success. She later assisted Rogers in handing over his team's equipment, which would indirectly spark the devastating Avengers Civil War. Her involvement in helping Rogers would cause Carter to go on the run.

In 2018, when Thanos obtained all of the Infinity Stones, he snapped his fingers, wiping out half of all life across the universe. Carter was amongst the victims in this catastrophic event, suddenly turning to dust. Fortunately, five years later, after the Avengers stole the Infinity Stones, Bruce Banner successfully brought everyone who had died back to life, returning to where they had disappeared.

She hooked up with Bucky Barnes when she leaned that Steve and Natasha were expecting a child. After her night with Bucky, she discovered that she was pregnant so she told him about the baby and told him that she didn't want the baby. After she had the baby and gave her to Bucky who Bucky named Stevie Barnes.

Sharon later worked with HYDRA and they used her to try and create a baby with Super Serum but they failed. While there they used Sharon to create Michael Fury but he only had a small amount of Super Serum and not enough for what they needed. Sharon escaped with the baby after she discovered they was just going to kill him and dropped him off at the New Avengers Facility before she disappeared, she later sent an email to Natasha explaining what happened and that she saw Sarah at HYDRA and what they wanted with Sarah.
