Chazz Princeton

Chazz Princeton, known in Japan as Jun Manjoume, is an arrogant duelist who serves as one of Jaden Yuki's rivals throughout the series. Chazz is considered Jaden's main rival in the same similarity as Seto Kaiba being the main rival to Yugi Muto. He and Jaden have dueled one another several times throughout the seasons anime. Originally, he used to be a duelist who only respects powerful cards to a duelist who believes any card can be effective. Since being one of the main characters of Yu-Gi-Oh! GX, Chazz has been fighting alongside his friends against the various threats in Duel Academy. Chazz like Jaden also has the ability to see duel spirits, to which he was able to see Ojama Yellow who then becomes his first Spirit Companion and afterwards Ojama Black and Ojama Green after Chazz acquires them.

In the ''Yu-Gi-Oh! GX'' manga, he has the same role in the anime series, but later becomes a deuteragonist.
