Card Appearances:D/D/D Chaos King Apocalypse

Yu-Gi-Oh! ARC-V

 * In episode 99, Declan Akaba uses this card during his duel against Jean-Michel Roget. Declan Special Summons this card from his hand using "Forbidden Dark Contract with the Swamp King", then uses "Forbidden Dark Contract's" other effect to immediately fuse it with "D/D Lamia" to Fusion Summon "D/D/D Dragonbane King Beowulf". Then, with the Pendulum Scales set at 6 and 8, he Pendulum Summons this card from his Extra Deck. Declan then tunes this card with the revived "Lamia" to Synchro Summon "D/D/D Cursed King Siegfried". When Roget rejoins the duel, Declan uses the Pendulum Effect of "D/D Savant Thomas" to add this card in his Extra Deck to his hand. This card subsequently forms part of the controlled loop where:
 * Declan Special Summons this card from his hand by destroying "Thomas" and "D/D Savant Nikola" in his Pendulum Zones.
 * "Nikola's" effect then activates, returning this card to Declan's hand and allowing Declan to place two face-up monsters in his Extra Deck onto his Pendulum Zones, but their effects are negated for the rest of the turn. Declan places "Thomas" and "Nikola" back on the Pendulum Zones.
 * Declan then activates the Continuous Trap "Dark Contract with the Swinging Abyss" to inflict damage to his opponent equal to the DEF of a "D/D" monster that was just returned to the hand. Since this card has 2000 DEF, Roget would lose no matter how many times he rejoins the duel.
