Natalia Romanova (Earth-1356)

"How many more jobs... How long will it take... I don't know if I can do it... Even if I could forgive myself... This is what I am now. And you'll never know who I was before."

- - Black Widow to Captain America

Natalia Romanova is the greatest spy and assassin in the whole world. Kidnapped by the KGB to serve in the Red Room, she outdid all of her fellow child competitors, gaining the chance of becoming the KGB's number one super soldier, the Black Canary, trained by the former Red Army sniper Ivan Petrovich, who raised her as his own daughter until his death. Enhanced with a special serum, she gained longevity, strength, and the ability to generate sonic screams. During a mission to Budapest, Canary was set to be assassinated by S.H.I.E.L.D. agent Hawkeye, but was instead given the chance to join S.H.I.E.L.D., which she accepted, becoming romantically involved with the archer.
