- In episode 4, Yami Yugi uses this card during his duel against Weevil Underwood. He equips this card to his "Feral Imp", increasing its ATK and DEF by 700. "Feral Imp" then attacks "Hercules Beetle", but the latter then destroys "Feral Imp" (which causes this card to be destroyed too). Weevil explains that monsters with a Field Power Bonus can negate the effects of Equip Spell Cards equipped onto monsters they battle.
- In episode 7, Yami Yugi uses this card during his Duel against Mako Tsunami. He equips this card to "Feral Imp", increasing its ATK and DEF by 700. Yugi believed that the electricity from this card should destroy Mako's monsters due to water conducting electricity. "Feral Imp" then attacks Mako's set monster, but it was revealed to be "Jellyfish", who isn't destroyed due to its immunity to electrical attacks. "Fiend Kraken" then attacks "Feral Imp". As "Fiend Kraken" had a Field Power Bonus, the effect of this card was negated. "Fiend Kraken" then destroys "Feral Imp". Since "Feral Imp" had been removed from the field, this card is destroyed.
