The name Sanzyudai appears to be a pun on Judai, which is Jaden Yuki's given name in the Japanese version. The name 十代 (jūdai) literally means "teenage" or "ages 10-19", befitting Jaden Yuki's youth. On the other hand, Sanzyudai appears to be significantly older than Jaden, which is reflected in the name 三十代 (sanjūdai), meaning "the thirties" or "ages 30-39".
In Yu-Gi-Oh! GX Tag Force 2 , to Sanzyudai's annoyance, he is partnered with Emperor.Umiuma, and in order to be allowed to change partners, he must duel at least once. He challenges the player and his partner to a Duel, and upon victory, he allows the player to partner with him. He appears during a Random Event at the Main Gate after the player has completed the Story Mode with 4 or more Page 1 Characters, and have beaten both Jaden and Yusei Fudo 15 or more times each.
