Card Appearances:Heraldry Catastrophe


 * In episode 62, Shark sets this card during his Duel against Yuma Tsukumo, but did not activate it. On the last turn, Yuma activates "Rivals Unite" to take control of "Chaos Number 32: Shark Drake Veiss" after he uses the effect of "Number 39: Utopia" to negate the attack "Utopia" made against "Shark Drake Veiss". While this removes Shark from Vetrix's control and restores Shark's memories, it also causes "Shark Drake Veiss" to inflict great pain on Yuma due to the Emperor's Key unable to protect Yuma from the power of "Shark Drake Veiss". Vetrix tells Shark to use this card to win the Duel as it will destroy both "Shark Drake Veiss" and "Utopia" and inflict their combined ATK to Yuma as damage and save his friend (as Vetrix anticipated Yuma would use a strategy to remove "Shark Drake Veiss" from Shark's side of the field to save him), however Shark was hesitant on winning since that would also mean Yuma and Astral would lose all the "Numbers" they had obtained (and Astral would be destroyed as well). At the same time, Yuma had the idea of using the effect of "Traplin" to destroy "Rivals Unite" and return "Shark Drake Veiss" to Shark's side to prevent the power of "Shark Drake Veiss" from hurting him despite that would mean Vetrix would be able to control Shark again. In the end, Shark activates "Underwater Snow Prison" (which was the first card he set during the Duel) to banish "Shark Drake Veiss" and take 1000 damage as a drawback, thus winning Yuma the Duel.
 * This card was given to Shark by Vetrix.
