Card Appearances:Number C65: King Overfiend
- In episode 102, Number 96 uses this card during his Duel against Astral. He Xyz Summons this card via "Rank-Up-Magic Barian's Force", which targeted "Number 65: Djinn Buster". Due to this card's last effect, the effects of "Swordsman of Revealing Light" are negated. Number 96 then activates this card's second effect to detach an Overlay Unit and reduce the ATK and DEF of "Swordsman of Revealing Light" by 1000. After "Number 96: Dark Mist" attacks and destroys "Swordsman of Revealing Light", this card attacks directly, but Astral activates "Xyz Reborn" to revive "Number 39: Utopia". A replay occurs and Number 96 chooses not to attack. Later Astral activates "Superior Overlay" to destroy Number 96's "Numbers" unless he detaches an Overlay Unit from them. Number 96 detaches the last Overlay Unit of "Dark Mist" to prevent its destruction while this card was destroyed.
- In episode 112, Vector obtains this card along with every "Number" in Number 96's possession after the power of Number 96 returned to Don Thousand.
- In episode 136, Vector uses this card during his Duel against Nash. He Special Summons this card from his Extra Deck via "Chaos Rising". Later this card attacks directly. Later Nash activates "Split Defender" to take control of the monster with the highest DEF (Vector's choice if it is a tie) with the intention of taking control of "Chaos Number 102: Archfiend Seraph" or "Chaos Number 103: Ragnafinity", but Vector activates "Guard Off" to reduce the DEF of all monsters he controls to 0 and inflict 400 damage to for each monster Vector controls that has 0 DEF. Nash activates "Xyz Charge Up" to reduce the damage he would take to 0. "Split Defender" then resolves and Vector chooses to give control of this card to Nash. Nash then activates the second effect of "Xyz Charge Up" to increase this card's ATK by the amount of damage "Xyz Charge Up" nullified (which was 1600). This card then attacks and destroys "Chaos Number 104: Umbral Horror Masquerade", revealing Vector's true memories. In the next episode, "Ragnafinity" (who Nash took control of via Vector's "Xyz Discharge"), attacks directly, but Vector activates "Trick Buster" to destroy all Attack Position monsters Nash controls and inflict 300 damage to Nash for each destroyed card. Nash then activates the effect of "Dream Shark" to make the damage he takes 0 and revive "Dream Shark".
