Natalia Alianovna "Natasha" Romanoff (Russian: Наталья Альяновна "Наташа" Романов) was one of the most talented spies and assassins in the entire world and a founding member of the Avengers. As a child, she was indoctrinated into the Red Room. Having extensive mastery in martial arts and armed with her Widow's Bite, Romanoff became one of S.H.I.E.L.D.'s most efficient agents, using the title given by her former organization as her codename, Black Widow.
