Black Widow  (Natalia Alianovna Romanova)
   
     Former member and past chair of the Avengers (tenth recruit); former founding member of the Lady Liberators; former founding member and leader of the Champions; past participant in the informal "Marvel Knights" vigilante alliance. 

     Formerly an infamous Russian spy, the Black Widow's brainwashed loyalty to her communist masters was broken by her love for the American adventurer Hawkeye, prompting her to defect. 

     After Hawkeye joined the Avengers, Black Widow enjoyed a lengthy vicarious membership of sorts since she often associated with the Avengers and sometimes assisted them in their cases. 
   

      She sought or was offered membership several times, but was initially rejected because of her communist past, and she later declined membership due to conflicts with her new activities as an American-based intelligence agent. She eventually ceased associating with the team after ending her romance with Hawkeye.

     Some time later, Black Widow finally accepted official membership in the Avengers but resigned almost immediately thereafter to concentrate upon her professional and romantic partnership with the adventurer Daredevil. After that alliance ended, she became a founding member and leader of the Champions, remaining with the group until it disbanded. She remained an Avengers reservist and assisted the team infrequently over the years, but eventually returned to full active membership when the group reorganized its roster under the auspices of the United Nations. This began a lengthy membership term which continued until the Onslaught disaster. Black Widow became close to team leader Captain America during that long stint, assisting him by assuming many of the team's organizational duties. When he took a leave of absence, she replaced him as team leader and retained the position until most of the Avengers seemingly perished in battle with Onslaught.

     The loss of almost the entire active roster under her leadership badly traumatized the Widow. She tried to rebuild the team, but her attempts to recruit new members and inactive Avengers were unsuccessful, and political pressure began building to suspend the group's operations. Finally, she formally disbanded the group, laying off its remaining staff and closing its hedquarters. When most of the Avengers lost in the Onslaught disaster turned up alive months later, the Black Widow helped reorganize the group and assisted the team against menaces such as the Deviants and Kang, though she declined full-time membership since she felt she was better suited to solo espionage than super-heroics. She has not served as a member of the Avengers since the team disbanded and reorganized following their clash with the insane Scarlet Witch.
