Card Appearances:Dark Blade the Dragon Knight
- In episode 126, Chazz Princeton uses this card during his duel against Jaden Yuki while the former was a Duel Ghoul. He summons this card via "Polymerization". Chazz then activates "Fusion Buster", equipping it to this card and increasing this card's ATK by 300. Chazz then activates the second effect of "Fusion Buster" to return "Elemental HERO Flame Wingman" to the Extra Deck and Special Summon "Elemental HERO Avian" and "Elemental HERO Burstinatrix" from Jaden's Graveyard to his side of the field. This card then attacks and destroys "Avian". On the last turn of the Duel, Jaden activates the effect of "Elemental HERO Grand Neos" to return this card to Chazz's hand (this card returns to Chazz's Extra Deck when this happens since this card is a Fusion Monster).
- Its attack name in both versions is Dark Sword Slash.
