|Anime debut||Yu-Gi-Oh! GX episode 24: "The New Chazz"|
Czar, known in Japan as Yuri Edogawa「江戸川遊離」(Edogawa Yūri), is the top Duelist in North Academy until Chazz Princeton defeats and dethrones him, which earns Chazz the right to compete in the School Duel against Duel Academy.
Czar also appears in a few flashbacks showing events at North Academy, such as one in episode 91, in which he defeats Lucien Grimley. He is usually seen in a rocking chair when not dueling, with Chazz calling him "Grandma" for this in the English dub.
After his match with Chazz however, his personality changes and he becomes more soft-hearted as well as humbled, with him and the rest of North Academy fully supporting Chazz to the point of crying when Chazz decides to stay in Duel Academy.
In the English version, Czar speaks with a Russian accent.
In Russian, Czar's name means "emperor".
