Yu-Gi-Oh! GX sports many different characters. The principal cast is composed of the series' hero Jaden Yuki (Judai Yuuki), the passionate Alexis Rhodes (Asuka Tenjoin) and her brother Atticus (Fubuki Tenjoin), the easily discouraged but determined Syrus Truesdale (Sho Marufuji), elitist Chazz Princeton (Jun Manjoume), the analytic Bastion Misawa (Daichi Misawa), the strong-willed Tyranno Hassleberry (Tyranno Kenzan), and the love-struck Blair Flannigan (Rei Saotome). Supporting characters often have connections to the educative or professional dueling worlds, and include Obelisk Blue professor Vellian Crowler, duelist-turned-Industrial Illusions designer Chumley Huffington, and Pro League powerhouses Zane Truesdale (Ryo Marufuji) and Aster Phoenix (Edo Phoenix). A group of foreign duelist champions, consisting of Jesse Andersen, Axel Brodie, Adrian Gecko and Jim Crocodile Cook, along with the new professor,
Thelonius Viper, would also find a place in Duel Academy's student body in the third year. In the fourth season a mysterious student named Yusuke Fujiwara appeared at the Duel Academy.
