Kaiba's Intergalactic Duel Monsters Tournament was a Duel Monsters Tournament that was held in the entire galaxy. Unlike the Smash World Grand Prix, it only went on during Season 17. The tournament was eventually suspended due to the threat of Yami Bakura and, at the time, Samus Aran. After Zorc Necrophades was defeated, the final match of the tournament was Naruto Uzumaki and Sasuke Uchiha vs. Yugi Muto and Seto Kaiba, with both teams summoning their ace monsters. Naruto and Sasuke were declared the champions of the tournament even though the match was a draw. The prize was a box containing nearly every card in existence, the only exceptions being the Egyptian Gods, Blue-Eyes White Dragon, and Red-Eyes Darkness Dragon.
