Card Appearances:Tristan, Knight of the Underworld

Manga

 * In Rank 39, Kyoji Yagumo uses this card during his duel against Shark. He Normal Summons this card. When Kyoji Special Summons "Isolde, Belle of the Underworld", this card gains 300 ATK through its own effect. Kyoji then uses "Belle's" effect on this card to double its Level, before overlaying this card with "Belle" (whose Level is also doubled) to Xyz Summon "Number 23: Lancelot, Dark Knight of the Underworld".
