In episode 104, Jaden Yuki uses this card during his duel against Sartorius. He Special Summons this card by Contact Fusing "Elemental HERO Neos" with "Neo-Spacian Grand Mole". This card then gains 500 ATK due to the effect of "Neo Space". Jaden then activates this card's effect to return "Arcana Force EX - The Light Ruler" to Sartorius' hand, but Sartorius activates "Reversal of Fate" to switch the direction of "The Light Ruler", making it upside down. Due to the Tails effect of "The Light Ruler", this card's effect is negated and it's destroyed. After that resolves, "The Light Ruler" loses 1000 ATK and Jaden draws a card. Jaden then activates "Reverse of Neos" to Special Summon "Neos" from his Deck with 1000 more ATK.
In episode 126, Jaden uses this card during his Duel against Chazz Princeton while the latter was a Duel Ghoul. He Special Summons this card by Contact Fusing "Elemental HERO Neos" with "Neo-Spacian Grand Mole". Jaden then activates this card's effect to return "Dark Blade the Dragon Knight" to Chazz's hand ("Dark Blade the Dragon Knight" goes back to the Extra Deck when this happens as it's is a Fusion Monster). This card then attacks directly, winning Jaden the duel. Chazz nearly falls into the abyss, but Jaden yells to this card to catch him. This card does so and sets Chazz on the ground before the former disappears.
Its effect name in the original is Nebulous Hole and its attack name is Nebula Shot.
