Card Appearances:Grave Squirmer
- In episode 150, Jesse Anderson uses this card during his Duel against Adrian Gecko while the former was possessed by Yubel. He Normal Summons this card in Attack Position. This card then attacks Adrian's "Fog King". The latter monster then destroys this card, but this activates the effect of this card, allowing Jesse to destroy "Royal Sword". Adrian then activates "Crest Burn" to place three Beacon Counters on "Fog Castle" since "Royal Sword" had three Crest Counters. This sends "Fog King" to the Graveyard as there were no more Monster Card Zones for it to be on.
- In episode 155, Yubel uses this card during her duel against Jaden Yuki. After Yubel activates "Chain Material" to allow her to banish monsters in her field, hand, Deck, and Graveyard and use those monsters as Fusion Material Monsters when she performs a Fusion Summon this turn, she chooses twelve monsters (which were this card, "Giant Germ", "Chaos Core", "Phantom of Chaos", "Dark Summoning Beast", "Infernal Incinerator", "Maju Garzett", "Lava Golem", "Infernal Flame Emperor", "Raviel, Lord of Phantasms", "Gate Guardian", and "Yubel - The Ultimate Nightmare") each with a consecutive Level from 1 to 12 from her field and hand as Fusion Material Monsters for "Super Fusion God". Yubel then activates this card to banish her twelve selected monsters from her Deck and field in order to Fusion Summon "Super Fusion God" (whose Summoning would unite the twelve dimensions into one), but Jaden activates "Spiritual Fusion" and selects to use "Super Polymerization" to fuse his soul with Yubel's. By doing this, Jaden frees Yubel from the Light's influence and unites her with the Supreme King forever.
- Its attack name is "Struggle Claw" in the Japanese version.
