Card Appearances:Number 17: Leviathan Dragon
Anime[edit]
- In episode 1, Shark uses this card during his Duel against Yuma Tsukumo. He Xyz Summons this card by overlaying "Big Jaws" and "Skull Kraken". Shark then activates this card's effect to detach "Skull Kraken" and increase its ATK by 500. This card then attacks and destroys "Gagaga Magician". In the next episode, "Gogogo Golem" (whose ATK was 2800 due to "Blustering Winds") attacks this card, but while Shark took Battle Damage, this card was not destroyed, as "Numbers" can only be destroyed by battle by another "Numbers". Later Shark activates this card's effect to detach "Big Jaws" and increase its ATK by 500. This card then attacks and destroys "Gogogo Golem". On Shark's next turn, this card attacks "Number 39: Utopia", but Yuma activates the effect of "Utopia" to negate the attack. On the last turn of the Duel, "Utopia" attacks this card and Yuma activates the effect of "Utopia" to negate the attack. Yuma then activates "Double or Nothing!" to double the ATK of "Utopia" and let it attack again. "Utopia" then attacks and destroys this card, winning Yuma the Duel. With Yuma's victory, Astral absorbs this card, freeing Shark from this card's influence.
- In the second above-mentioned episode, this card appears in Astral's thoughts when he explains in detail to Yuma about the "Numbers" and how they work.
- In episode 3, Yuma checks his Extra Deck during his Duel against Mr. Kay and finds this card and "Leviathan Dragon" inside, much to his relief (Yuma is surprised to see "Leviathan Dragon" inside his Extra Deck). Yuma wonders if Astral took those Numbers with him when he briefly disappeared. Astral explains that Yuma has access to the "Numbers" that he had absorbed.
- This card also appears in a flashback Astral has when he notes if humans operate in perfect combination through eating and using the bathroom why is Yuma's Dueling incompetent.
- This card also appears in a flashback Astral has when he notes even though his memories have been trapped in 99 different "Numbers" and then scattered, his memories won't return until he gathers them all.
- In episode 4, Yuma uses this card during his Duel against Mr. Kay. He Xyz Summons this card by overlaying "Zubaba Knight" and "Achacha Archer". Due to the effect of "Super Crashbug", this card's ATK and DEF are switched. After "Super Crashbug" is destroyed by the effect of "Overconfidence", the ATK and DEF of all monsters on the field return to their original values. This card then attacks and destroys "Number 34: Terror-Byte". This card remained on the field until the Duel was over.

After Flip activates the Flip Effect of "Flipangutan" to switch "Baby Tiragon" to Attack Position, this card attacks "Baby Tiragon", but Yuma activates "Half Unbreak" to prevent "Baby Tiragon" from being destroyed in battle this turn and halve all Battle Damage he takes this turn. After Yuma activates the effect of "Stinging Swordsman" to return "Ultra C" and "Traitor Fog" to Flip's hand, the second-to-last effects of both "Traitor Fog" and "Ultra C" give control of this card and "Utopia" to Yuma. This card then attacks and destroys Flip's Set "Flipangutan". This card remained on the field until the Duel was over.

- In episode 14, Yuma uses this card during his Duel against Kite Tenjo.

Yu-Gi-Oh! ZEXAL[edit]
- In Rank 2, Shark plays this card against Yuma Tsukumo. He overlays "Big Jaws" and "Skull Kraken" to Xyz Summon it. Using its effect, he detaches "Skull Kraken" to increase its ATK by 500. It attacks and destroys Yuma's "Gagaga Magician". In the next Rank, Yuma attempts to destroy this card with "Gogogo Golem", whose ATK was increased via "Blustering Winds". It does not work, as a "Number" monster can only be destroyed by battle with another "Number" monster. Shark detaches the overlaid "Big Jaws" to increase its ATK by another 500. It attacks and destroys "Gogogo Golem". In the next Rank, Shark attacks Yuma's "Number 39: Utopia" with this card. Yuma negates the attack with the effect of "Utopia" by detaching the overlaid "Ganbara Knight". On his turn, Yuma attacks this card with "Utopia", but negates his own attack by detaching the overlaid "Gagaga Magician". This lets him activate "Double or Nothing!", doubling the ATK of "Utopia" and letting it attack again. This card is destroyed and Shark loses. The card is absorbed by Astral afterwards.
- In Rank 6, Yuma plays this card against Tokunosuke Hyori. He overlays "Rai Rider" and "Gagaga Magician" to Xyz Summon it after changing the Level of the latter card to 3 via its own effect. Tokunosuke activates "Mistrust" to take control of it. Tokunosuke detaches an Overlay Unit to increase this card's ATK by 500 and attacks "Baby Tragon" with it, but Yuma protects it with "Half Unbreak".
