- In episode 131, Vector uses this card during his Duel against Dumon and Marin. Since Vector had two copies of this card in his hand, he Special Summons both via their own effects. After Vector Normal Summons "Umbral Horror Will o' the Wisp", he activates the latter's effect to make its Level the same as this card's. He then overlays both copies and "Umbral Horror Will o' the Wisp" in order to Xyz Summon "Number 96: Dark Mist". After "Dark Mist" is destroyed by the effect of "Number 103: Ragnazero", all Overlay Units of "Dark Mist" go to the Graveyard. During the End Phase, Vector activates "Nightmare Xyz" to revive both copies and "Umbral Horror Will o' the Wisp" and make the summoned monsters Level 3. Vector then activates the final effect of "Nightmare Xyz" to overlay the two copies and "Umbral Horror Will o' the Wisp" in order to Xyz Summon "Number 43: Manipulator of Souls". Two episodes later, the Overlay Units of "Manipulator of Souls" are attached to "Chaos Number 43: High Manipulator of Chaos" after the latter is summoned via the final effect of "Don Thousand's Throne".
