|Anime debut||Yu-Gi-Oh! GX episode 02424: "The New Chazz"|
Czar, known as Yuri Edogawa (江戸川遊離 Edogawa Yūri) in Japanese, was the top Duelist in North Academy. Chazz Princeton challenges and defeats him, which earns Chazz the right to represent North Academy 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; in the English dub, Chazz calls him "Grandma" for this reason.
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.
Czar means "emperor" in Russian.
