Overseas Champions

The Overseas Champions are four duelists from four seperate branches of Duel Academy who debut in the third season. They were enrolled into the original Duel Academy in order to increase the school's expanding influence. The champions are the star duelists from their respective schools and therefore allowed to stay in the Obelisk Blue Dorm. These highly-skilled duelists serve as allies to Jaden Yuki and co., save for one, who eventually becomes a major antagonist of his own free will.

History
Arriving shortly after the start of the school year in the third season, they are introduced, along with Professor Thelonius Viper, to the students and faculty. Soon after, one the champions, Jesse Anderson, is selected to duel Jaden Yuki by Viper in a exhibition match, after which Viper introduces the concept of Survival Duels to the students.

During the Survival Duels, the champions act on their own agendas, during which, Jim Crocodile Cook and Jesse hang out with Jaden and the others. Axel Brodie, during this time, duels Jaden so Viper may extract all his Duel energy while another champion, Adrian Gecko, attempts to undermine Viper's operation.

When Duel Academy is transported to another dimension, they assist Jaden and co., except for Adrian who sticks to his own agenda, into finding way to return home by using the power of Rainbow Dragon. During a duel with the mastermind behind the Martin Empire, Yubel, Jesse finally uses Rainbow Dragon to restore Duel Academy to its original place.

They later assist Jaden and co. in their efforts to rescue Jesse who is still trapped. During this mission, Jim and Axel join forces with the few remaining main duelists to defeat Jaden, who had become the Supreme King after being possessed by Haou the Supreme King, although Jim and Axel are sucessful, they are incapacitated. After Haou's fall, Adrian establishes himself as an antagonist and intends to rule the alternate dimension while Jesse is possessed by Yubel.
