Romanova is later revealed as a traitor—claiming that she betrayed the Ultimates because she feels that America has turned her country into a collection of drug-runners and prostitutes—responsible for killing Hawkeye's wife and children, revealing Bruce Banner's connection to the Hulk to the public, helping to frame Captain America as a traitor, and collaborating with the Liberators in their invasion of the United States. After she murders Edwin Jarvis and holds Stark hostage in an attempt to extort his fortune, Stark activates the nanites in her bloodstream, freezing her body in place, before knocking her unconscious with a wine bottle. She appears later in an emergency clinic, having cut open her wrists to bleed out the disabling nanites. Hawkeye kills her in revenge for her part in the murder of his family.
