Prior Events
After the duel between Téa Gardner and Mai Valentine, The group climb to the top of the stairs. They are intercepted by Kemo, who informs them that only duelists with 10 star chips can enter, to which Yugi Muto, Joey Wheeler and Mai all qualify. Mai also distracts Kemo so Tea, Tristan Taylor and Bakura can enter. They soon run into Bandit Keith, and after a minor scuffle, they are greeted by Croquet, who tells them as congratulations for making it so far in the Duelist Kingdom tournament, Maximillion Pegasus has prepared some entertainment: An exhibition duel between the former champion Seto Kaiba and Duel Monsters creator Pegasus himself.

Kaiba was not pleased about what Pegasus had done and vows to save his brother Mokuba Kaiba. Joey and Tristan agree that even though Kaiba is a creep, anyone who stands up to Pegasus can't be all bad and Yugi thinks highly of Kaiba since he, like Yugi, is fighting for someone he cares for.

Kaiba proposes they use his Duel Disks but Pegasus goofs a little until he makes a counter-proposal: Have someone duel for him while he gives advice to his representative. He has one of his guards bring out Mokuba, whose soul was stolen by Pegasus. Yugi suddenly realized this was the reason why Kaiba risked his own life during their duel. Yugi tries to offer Kaiba help but the latter refuses. As Pegasus was about to finalize the terms of the duel, using the duel disk but having Mokuba operate it for him, Kaiba backs down refusing to duel his brother since he has been through enough. The duel then proceeds.

Turn 4: Kaiba Kaiba draws. He then tries to Normal Summon "Blue-Eyes White Dragon", but Pegasus activates his face-down "Prophecy" to let him predict if the ATK of Kaiba's card is more, equal to, or less than 2000. If he is correct, the card will be added to his hand. Pegasus guesses that the card Kaiba is trying to play has over 2000 ATK and guesses that card in question is "Blue-Eyes White Dragon". He is correct, so "Blue-Eyes White Dragon" is added to his hand. Kaiba switches "Rude Kaiser" to Defense Position.

Turn 5: Pegasus Pegasus draws. At this point in the duel, Pegasus uses the power of his Millenium Eye to see the cards in Kaiba's hand. He notices "Crush Card Virus" and "Saggi the Dark Clown" realizing Kaiba's endgame is to use them in a combo. Pegasus prepares a counter for this by setting a card and a monster.

Turn 7: Pegasus Pegasus draws. He then activates his face-down "Negative Energy" to double the ATK of every DARK monster on the field ("Saggi the Dark Clown": 600 → 1200/1500). Since the ATK of "Saggi the Dark Clown" is now over 1000, "Crush Card" cannot be activated. Pegasus then Flip Summons.

Now any monsters Pegasus controls can be transformed into Toon monsters. Also any monsters that are within the pages of "Toon World" cannot be attacked by Kaiba's monsters.

Turn 13: Pegasus Pegasus draws. He thinks to himself that since Kaiba abandoned his hand he can't look at any cards, but decides to peer into Kaiba's mind since he has memorized every card in his deck and prepares a counterattack.
