Natalia Alianovna Romanova

Natalia Alianovna Romanova a.k.a. Black Widow was a former Russian KGB agent. She was trained by the "Red Room" as part of the Black Widow Ops Program to be the ultimate "Super-Spy". She defected to the United States of America from the Soviet Union to join S.H.I.E.L.D. Later Black Widow would then become a member of the Avengers and has been on the team on multiple occasions. She is a woman with a mysterious past which few know about. Natasha is a professional and sly agent who will get any job done regardless of the difficulty. She went from being one of the best operatives in S.H.I.E.L.D. to a super hero. She held her own as a part of the Avengers for years, even leading them for a time. However, she doesn't belong with the super hero set due to her helping with S.H.I.E.L.D. Nevertheless, she will keep her word by being behind the scenes or assist the Avengers if needed. Despite Natasha being a super hero, she will always resume her mission to be a spy. Nick Fury commented on Natasha that "running in the shadows is what she was born to do."
