North Academy

Chancellor Foster
Chancellor Foster, known in Japan as Ichinose (市ノ瀬) is the head of North Academy. Foster first appears to Chazz disguised, and gives him the Ojama Yellow card. Afterwards, he helps Chazz in gaining access to the school to duel its top duelist Czar and gives him the rare Armed Dragon series. Later on, Foster places a bet on the outcome of the duel between Chazz and Jaden with Chancellor Sheppard. The prize, however, turns out to be nothing more than a kiss from Ms. Dorothy.

In the English dub, Foster is voiced by Darren Dunstan, while Izumi Shoji takes the role in the Japanese version.

Czar
Czar, known in Japan as Yuri Edogawa (江戸川遊離, Edogawa Yūri) is the top duelist in North Academy until Chazz beats him. Afterwards, he and the rest of his gang fully support Chazz and cry when he decides to stay at Duel Academy. Czar's also seen a few flashbacks such as the one showing Lucien Grimley's defeat.

In the English dub, he's voiced by Sean Schemmel, while Yoshikazu Nagano is the voice actor in the Japanese version.

The Czar plays a Devil/Zoa Deck, which focuses on the summoning of the eponymous card and its upgraded Metalzoa form.

Lucien Grimley
Lucien Grimley, known in Japan as Ikaku Tachibana (橘一角, Tachibana Ikaku) is a duelist who enters the Genex tournament from North Academy. A failing duelist originally from North Academy, Lucien makes a deal with the malevolent spirit of the forbidden and cursed Grim Reaper (voiced by Scottie Ray / Shinobu Matsumoto) card sealed by the school, selling his soul to obtain incredible draw power. The reaper imbues his right hand with the symbol of himself. Although he claims that his goal is to be victor of the Genex tournament, his true wish was to experience a trusting bond with his deck. He duels Jaden and later discards the Reaper breaking his contract with him after getting enough faith in his deck to draw by himself. He eventually loses to Jaden but promises not to lose trust in himself again. To that end, he threw the Reaper's card away, committed to winning without its assistance.

In the English dub, Lucien is voiced by David Wills, while Kazuhiro Nakata takes the role in the Japanese version.

Lucien plays a Reaper Deck. Using various Spell Cards to force his opponents to automatically play or set cards on the field, he builds up to a certain number before activating Slash Draw to instantly wipe out his opponents' Life Points after he draws another copy from his deck. As a back-up, Lucein's Invincible Demise Lord can revive itself with near invincibility to destruction, allowing it to survive the effect of Slash Draw, which would destroy it under normal circumstances.
