Jacques "Jack" Duquesne is a wealthy socialite and talented swordsman who became engaged to Eleanor Bishop. In December 2024, Jack was suspected by Eleanor's daughter Kate Bishop when his uncle Armand Duquesne III was murdered. However, Eleanor did it and framed Jack for his death, and also pinned his name to a shell corporation that laundered money for the Tracksuit Mafia. Although Duquesne was quickly released and proven innocent, he learned Eleanor had deceived him and joined Kate, Hawkeye and their allies in fighting off the Tracksuits during the Battle at Rockefeller Center. In 2027, Duquesne came across someone in need of help and used his swordsmanship to rescue them, being dubbed Swordsman by the public. He continued his activities as a member of New York City's elite, attending fundraisers and balls held by mayor Wilson Fisk. Duquesne was skeptical of Fisk's involvement in the Red Hook Port Revitalization Project, although Fisk threatened to out Duquesne as Swordsman, leading him to support the project.
