Romanova grew up to serve as a femme fatale. She was assigned to assist Boris Turgenov in the assassination of Professor Anton Vanko for defecting from the Soviet Union, which served as her first mission in the United States. Natasha and Turgenov infiltrated Stark Industries as part of the plan. She attempted to manipulate information from American defense contractor Tony Stark, and inevitably confronted his superhero alter ego, Iron Man. The pair then battled Iron Man, and Turgenov stole and wore the Crimson Dynamo suit. Vanko sacrificed himself to save Iron Man, killing Turgenov in the process, using an unstable experimental laser light pistol. Romanova later meets the criminal archer Hawkeye and sets him against Iron Man, and later helped Hawkeye battle Iron Man.
