Slade Princeton

Slade Princeton, known as Chosaku Manjoume「万丈目長作」(Manjōme Chōsaku) in the Japanese version, is one Chazz's two older brothers. Slade is at the top of the political world; while his brother Jagger is at the top of the financial world. They wanted Chazz to make the two of them be at the top. When it came to the duel-off against North Academy and Duel Academy, he and Jagger wanted Chazz to use their rare and powerful dragon cards that they provided him only to discover that he used the Armed Dragon deck he got at North Academy. After Chazz loses to Jaden, both of them get mad at Chazz. After some words from Jaden, both Slade and Jagger tell him and his friends that they are disowning him.

Near the middle of the 1st season, he and Jagger make a deal with Seto Kaiba that if he is able to defeat one of Duel Academy's students, they'll be allowed to buy the academy from him and do whatever they wish with it. Slade then challenges Chazz to a duel under the conditions that Chazz must use an extremely weak deck while he himself may use one filled with rare and powerful dragon cards (the same ones that Chazz didn't use when he was representing North Academy). However, he is defeated with the help of the Ojama Trio. Afterwards, Slade along with Jagger leave Duel Academy. Seto Kaiba got word of Slade's defeat and told one of his workers that Slade and Jagger have a long way to go if they want world domination.

The last time he is seen is after the Sacred Beasts crisis when their cards came back.

His English name is most likely a based on the Rockstar Slade.
