In episode 162, Joey Wheeler uses this card during his Duel against Rex Raptor. He creates this card by merging "Red-Eyes Black Dragon" with "Claw of Hermos". Joey then equips this card onto "Gearfried the Swordmaster", increasing its ATK by 1000. Since Rex had a Dragon-type monster on his side of the field, this card increased the ATK of "Gearfried" by an additional 500. Since "Gearfried" was equipped with an Equip Card, its effect activates, allowing Joey to destroy Rex's "Tyrant Dragon". Since "Tyrant Dragon" was removed from the field, "Gearfried" lost 500 ATK. "Gearfried the Swordmaster" then attacks directly, winning Joey the Duel.
