With Zigfried and Leon ready to square off in the KC Grand Championship finals, Kaiba appears and announces that the match is invalid and proclaims Leon Wilson to be the winner of the duel. Then he tells Zigfried that he knows that his true identity is Zigfried Von Schroeder, CEO and President of Schroeder Corp and challenges him to a duel. As Kaiba and Zigfried begin their duel, Zigfried starts off by playing his magic card Ride of the Valkyries on his first turn. Throughout the rest of the duel, he continues to pummel Kaiba with his Valkyrie monsters, but Kaiba remains unaffected and counters all of Zigfried's main offenses. However, things begin to turn in Zigfried's favor, as he plays Nibelung's Ring on Kaiba's XYZ Dragon Cannon and then plays Fortune Chariot, which lets him bypass Kaiba's monsters and directly attack him.
