In episode 81, the Guard Robot uses this card during its Ground Duel against Yusei Fudo. It activates this card to prevent Yusei from attacking with Level 4 or higher monsters as it knew most of Yusei's strongest monsters were higher than Level 4. Due to this card's effect, "Junk Warrior" is switched to Defense Position. In the next episode, this card switches "Earthquake Giant" to Defense Position after Yusei Normal Summons it. This activates the effect of "Earthquake Giant", allowing Yusei to switch "Lock Dragon" to Attack Position. Yusei then activates "Panic Wave" to negate the effects of all Continuous Spell Cards, Continuous Trap Cards, and Effect Monsters the Guard Robot controls (which includes this card). This card remained on the field until the Duel was over.
