In the English version, Chazz is voiced by Tony Salerno from episodes 1-89 and by Marc Thompson from episode 90 and onwards, while Taiki Matsuno takes the role in the Japanese version. Chazz is initially portrayed as an antagonist but eventually serves as one of Jaden Yuki's rivals throughout the series. However, it is revealed early in the first season of the series that his elitism stems from his older brothers who urge him to become a great duelist in order to have their family reign over the dueling world, as his brothers rule over the political and financial worlds. After becoming estranged with his brothers, Chazz decides to pursue a career in dueling without their help. It is revealed that Chazz has a soft side in the second season. When Alexis's brother arrives to take Alexis to make a band, they have a duel. During the duel, Chazz cheers on Alexis calling her "Lexi". Later during the second year in the Duel Academy, Chazz loses to a duel with Master Sartorius; duel manager of Aster Phoenix and becomes a member of the Society of Light.

He initially uses a power based deck, focusing on powerful monsters such as the Armor Dragons. Later on, he becomes able to see duel spirits and starts using the Ojama Trio, a trio of brothers with zero attack points but several uses.

His self-imposed nickname in the English version is "The Chazz" while his Japanese nickname is "Manjoume Thunder", which is spawned from the phrase . In the manga, Chazz is a more serious character than his anime counterpart, and his main spirit card is Light and Darkness Dragon.
