Card Appearances:Rivals Unite

• In episode 61, this card is shown in Yuma Tsukumo's hand during his Duel against Shark. In the next episode, Yuma activates this card 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 his set "Heraldry Catastrophe", which will destroy both "Shark Drake Veiss" and "Utopia" and inflict their combined ATK to Yuma as damage to save his friend, 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 this card 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.
