Natasha Romanoff

Natalia Alianovna "Natasha" Romanova, also known as Black Widow (or Romanoff; Russian: Наталья Наташа Романоф Альяновна Романова), is one of the most talented spies and assassins in the entire world and a founding member of the Avengers. She is the wife of Captain Steven Rogers, the mother of James, Sarah, and Francis Rogers and the step-mom of Michael Fury.

Biography
Originally a KGB operative and dangerous assassin, Romanoff was recruited into S.H.I.E.L.D. by Clint Barton. Having extensive mastery in martial arts and armed with her Widow's Bite, Black Widow became one of S.H.I.E.L.D.'s most efficient agents.

During one mission, she was sent undercover into Stark Industries to watch Tony Stark due to the fear that he was dying. During this mission, Romanoff assisted Stark with defeating Ivan Vanko's terrorist plots against him.

When Loki declared war on the Earth, Black Widow was recruited into the Avengers after Hawkeye had just been enthralled by Loki. Romanoff assisted in recruiting Stark and Bruce Banner into the team while they tracked down and attempted to capture Loki, eventually saving Barton from his grasp. Once Loki's entire plan had been uncovered, Romanoff joined the team during the Battle of New York and was instrumental in destroying the portal over the city which had been created by the Tesseract, effectively ending the entire invasion while Loki was defeated and captured.

In the wake of the Avengers successfully defeating Loki, Romanoff had continued her work with S.H.I.E.L.D., this time working with Captain America. While working together, Romanoff and Rogers uncovered a conspiracy following an assassination attempt on Nick Fury, which had eventually led to them discovering that HYDRA had somehow been infiltrating their entire organization. Despite the efforts of the Winter Soldier to stop them, Romanoff helped expose Alexander Pierce's evil schemes to the world, which also resulted in all of her own morally dubious history being revealed. As a result, Romanoff was forced into dropping off the grid again and began rebuilding her cover.

Romanoff eventually rejoined the Avengers, working to bring down various HYDRA cells across the world and assisting in the capture of Wolfgang von Strucker. However, before she could form a romantic relationship with Banner, the rogue artificial intelligence Ultron was created by Stark and Banner, forcing Romanoff and the rest of their team to join together and defeat him. Despite being captured, Romanoff was able to inform the team of Ultron's location on Sokovia, resulting in a final battle in which the Avengers had defeated Ultron once and for all. Unlike most members of the original Avengers, Black Widow remained a member while forming the second incarnation of the team.

As many of the governments of the world had demanded the Avengers to sign the Sokovia Accords in the wake of their recent battles, Romanoff agreed to their terms and signed the Accords. She later joined Iron Man in a fight against Captain America due to his disagreements with the Accords and his criminal activities with the Winter Soldier who Rogers was attempting to protect. As the two Avengers' factions fought against each other, Romanoff betrayed Iron Man's team to assist Captain America to find the instigator of the team's fight. As a result, Black Widow had to escape from the government for aiding Rogers, while being on the run, Romanoff soon joined him and Wilson in stopping terrorists.

When the threat of Thanos approached Earth, Romanoff, Rogers, and Wilson protected Vision, who had the Mind Stone, which Thanos was after. They later defended Wakanda from the attack, but were ultimately defeated when Thanos destroyed half of all life with the Infinity Gauntlet, where Romanoff emerged as one of the survivors. Romanoff was part of the Ambush on Thanos in an effort to retrieve the Infinity Stones and undo the Titan's snap, with no success.

Five years later, Romanoff led the Avengers alongside Captain America, now formed by Okoye, Rocket Raccoon, Nebula, War Machine, and Captain Marvel. To undo the Snap, the remaining Avengers split up into teams to retrieve all Infinity Stones from several alternate timelines in the Time Heist. Sent to retrieve the Soul Stone on Vormir with Barton, Romanoff, against Barton's insistence, willingly jumped off the Vormir mountains into the abyss below, sacrificing herself in the process in order to obtain the Soul Stone for the Avengers.

When Steve returned the stones, he found a way to bring Natasha back along with Tony. The following year, Steve and Natasha started a relationship. Steve proposed to Natasha and before their wedding, Natasha discovered that they are expecting a child. In January 2025, Natasha gave birth to twins, James Rogers and Sarah Rogers.

While on a mission, the twins were staying with Bucky Barnes and Wanda Maximoff. Sarah was taken along with Evie. She spent the next five years trying to track the people who took Sarah. She became obsessed with getting Sarah back that she left Steve practically alone to raise James. Three years after Sarah was taken, Bucky was taken by the same people but the trail went cold again.

Soon after Sarah was taken Natasha was at the New Avengers facility with Nick when a baby was dropped off at the door, Nick had a DNA test ran on through the Database and Natasha was furious when she discovered that the baby when the results came back positive to Steve and Sharon. Natasha left the facility and stormed into her house, she attacked Steve when she entered their house. Bucky, Sam, Tony, and Pepper had to pull her off of him. Steve tried to talk to Natasha but she started to yell in Russian which only Bucky understood. Bucky defended Steve saying "He would never do that". To which Natasha yelled at him to shut up the baby she dropped off to Fury told a different story. Steve tried to calm Natasha down but she pushed him away. He asked her what was going on and she told him about the baby before she slammed the results against his chest and went up stairs to James's room, she locked his door and started crying. Steve walked up to James's room and heard Natasha crying. Steve tried to get her to open the door swearing that he didn't cheat on her.

Natasha left Steve upstairs and went downstairs to hear the others theory that Steve's genetics were stolen while he was in the hospital.
