Duel Monsters Quest
20 February 2001 – 6 March 2001
Seto Kaiba went to fire The Big Five after finding out about their little scheme to take over KaibaCorp. The Big 5 challenge him to a virtual game, and if he wins, they will resign their posts. Unfortunately, inside the game Kaiba's Blue-Eyes White Dragon was captured by a "Dragon Capture Jar". Kaiba himself is then captured by the "Witty Phantom", who wishes to sacrifice him to the "Five-Headed Dragon".
Mokuba Kaiba runs to Yugi Muto for help. Yugi, Téa Gardner, Joey Wheeler, and Tristan Taylor all run to KaibaCorp. Yugi, Joey, and Mokuba get into the virtual pods, which transfer them to a virtual world. On the way, Joey is forced to duel with Mai Valentine. When she finds out her opponent is Joey (they were both masked), she joins in the search for Kaiba.
On the way they encounter a maze. Joey hears a girl crying and attempts to rescue her. (Mai disgustedly observes that Joey is too easily attracted to maidens in distress.) Joey finds a princess who looks like Mokuba. (Joey initially thinks that the princess is Mokuba, and asks why he is wearing a dress. Mokuba appears behind him and explains that he is there.) The princess says she is about to be the sacrificed to the Five-Headed Dragon.
The four become guests to a royal feast. The princess explains everything about the Five-Headed Dragon. When they are ready to go vanquish the dragon, the princess is suddenly captured. However it is actually Mokuba in disguise. The remaining three heroes give chase, destroying many obstacles in their way. Finally, they get to the Kaibas. But then, the Big 5 cheat by re-writing the program and summon the Five-Headed Dragon themselves. After many sacrifices leaving only Yugi and Kaiba standing, they finally vanquish the dragon, by fusing Kaiba's Blue-Eyes Ultimate Dragon and Yugi's Black Luster Soldier into the Dragon Master Knight.
A loose adaptation of this arc resulted in the video game Yu-Gi-Oh! The Falsebound Kingdom.
