Gozaburo Kaiba (Nightmare Troubadour)
|Video game debut||Yu-Gi-Oh! Nightmare Troubadour|
After the player defeats Noah Kaiba and he allows everyone to leave his Virtual World, Gozaburo reveals himself and blocks the way, intending to lock everyone inside until its incoming destruction. He duels the player in a Shadow Game under the effect of "Final Countdown", forcing the player to defeat him in 20 turns or less. After Gozaburo's defeat, Noah helps the player and everyone else escape, but Noah, The Big Five and Gozaburo himself all have their uploaded minds destroyed.
Gozaburo makes no other storyline appearances, but the player can Duel against him as part of the first Duel Course in the Duel Base after finishing the game and being at least Level 20. Finishing the second Duel Course earns the player Gozaburo's Deck Recipe.
