Noah Kaiba (Nightmare Troubadour)
|Japanese translated||Noah Kaiba|
|Video game debut||Yu-Gi-Oh! Nightmare Troubadour|
Noah's event begins once the player is at least Level 12 and has defeated Yami Bakura for the first time.
When the last member of The Big Five is defeated, Noah summons the player to his Duel Base and challenges him to a Shadow Game through Mokuba. Once Mokuba is defeated and released from his control, Noah then duels the player himself.
After Mokuba expresses sympathy towards Noah, he admits everyone had their minds uploaded into his Virtual World at the mansion and gives up his plans, allowing everyone to leave. However, the player is forced to duel Noah's father, Gozaburo, in order to escape the Virtual World. Noah then stalls the weakened Gozaburo, sacrificing himself to make sure his father does not escape the Virtual World's destruction.
Noah makes no further appearances in the storyline, but the player can duel against Noah as part of the first Duel Course in the Duel Base, which becomes available after finishing the game and reaching Level 20. Finishing said Duel Course also earns the player Noah's Deck Recipe.
