*Sherry LeBlanc is a female Turbo Duelist of French origin. Competing in the WRGP, she seeks to defeat Iliaster who's behind the tournament and orchestrated the death of her parents. She attempts to recruit Yusei Fudo on her team, with the intention of uncovering Iliaster's schemes through the Signers. It was only after she learns the fate of the future that she shifts her allegiance to Iliaster, as she aided in Z-one's plan to destroy New Domino City in return for having her family brought back. After being defeated by Akiza Izinski and Crow Hogan, Sherry returns to help protect New Domino City, keeping her promise to her father to fight for justice.

Sherry has long blond hair reaching past her waist with bangs that curl away from her face in a horizontal direction and has emerald color eyes. Her Turbo Duel uniform is white with red accents that run along the outside of her arms, down the outside of her legs, and wrap around her calves. She also wears a red undershirt. Her uniform also consists of grey shoulder, knee, elbow, and shin guards, while she wears charcoal colored padding over her chest. Her helmet is also red with gold accents near the crown that run from front to back, while the open-mouthed mouth protector is grey, with an orange visor.

Since her defection to Z-one, Sherry's uniform has now changed radically from her old attire. It now consists of a black and white scheme that inverts from both sides of her suit, with grey pauldrons instead of shoulder pads and a black lining with white laces down the middle of her body. Her undershirt remains the same though.

Sherry has a fixation on getting vengeance against Iliaster due to them having killed her parents. To this end, she can be very ruthless in doing so, such as grabbing a person and throwing them out of a building. However her anger towards Iliaster vanishes when their leader shows her the ruined future caused by Ener-D, deciding to aid them in return that her family is brought back as well She shows remorse and cries after Akiza and Crow defeat her, realizing her mistake and sides with Team 5D's again. She displays new resolve when Z-one questions Sherry cooperating with Team 5D's, saying the past cannot be changed and that she's going to live for the future.*
