In episode 134, Yami Yugi uses this card during his Duel against Seto Kaiba. He summons this card via "Polymerization" (which Yugi activated via "Double Spell"). Since two Dragons were face-up on the field, this card gained 1000 ATK. On Kaiba's next turn, he uses "Blue-Eyes Ultimate Dragon" to attack "Red-Eyes B. Dragon", but Yugi activates "Magic Formula" to equip the latter to this card and increase this card's ATK by 500. Kaiba then activates "Absorb Spell" to change the target of "Magic Formula" to "Blue-Eyes Ultimate Dragon" instead. Yugi then activates "De-Fusion" to return "Blue-Eyes Ultimate Dragon" to the Extra Deck and Special Summon the three "Blue-Eyes White Dragons" in Kaiba's Graveyard to his side of the field. Since there are now four Dragon-type monsters on the field, this card's ATK increased to 4900. On the last turn, Yugi activates "Diffusion Wave-Motion" to allow this card to attack all monsters Kaiba controls once each. This card then attacks and destroys all three "Blue-Eyes White Dragons", winning Yugi the duel.
