Natalia Alianovna “Natasha” Romanoff, better known as Black Widow, is one of the most talented spies and assassins in the entire world and a founding member of the Avengers. Originally an agent of the Soviet agency for foreign intelligence, the KGB, she later became a member of S.H.I.E.L.D., the international counter-intelligence agency. 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 fears that he was dying. During this mission, Romanoff had assisted Stark with defeating Ivan Vanko’s terrorist plots against him.
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 fellow agent Captain America. While working together, Romanoff and Rogers uncovered a conspiracy following an assassination attempt on director 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 to the world. As a result, Romanoff was forced into dropping off the grid again to begin rebuilding her cover.
Romanoff eventually rejoined the Avengers, working to bring down various HYDRA cells across the world and assisting in the capture of their leader, Baron Wolfgang von Strucker. However, before she could form a romantic relationship with Bruce Banner, the rogue artificial intelligence Ultron was created by Tony 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.
