|Relatives||Slade and Jigger Princeton (Brothers)|

Chazz Princeton, known in Japan as Jun Manjoume (万丈目準, Manjōme Jun), and in the Philippines as "Shawn Banzaime", is an arrogant duelist who serves as one of Jaden's rivals throughout the series. Jaden has dueled him far more times (a total of six) than any of his other opponents in the series. Through his evolution, he goes from being a duelist who only respected powerful cards to a duelist who believes that there can be effectiveness in any card.
Chazz is considered Jaden's main rival in the same effect that Seto Kaiba is the rival of Yugi Muto. However, their rivalry has since lessened as Chazz's character evolved and he developed a begrudging respect for Jaden's abilities
Chazz's character design was overseen by Kenichi Hara. His usual outfit consists of a slightly tattered black jacket with grey trimmings and sharp edges, though he has also worn the standard Obelisk Blue uniform, flowing out the costume's lower back. His black hair is sectioned in two layers, his black eyes positioned directly beneath the bangs of the layer closest to his face. He carries an Academy-issued Duel Disk on his left hand.
