In episode 108, this card is shown in Kaiba's hand during his Duel against Leichter. In the next episode, "Spirit Ryu" attacks "Injection Fairy Lily". Leicther then activates the effect of "Injection Fairy Lily", paying 2000 Life Points to increase the ATK of "Injection Fairy Lily" by 3000 during the Damage Step only. Kaiba then activates this card's effect to discard this card and "Cave Dragon" and increase the ATK of "Spirit Ryu" by 2000 (1000 for each Dragon-type monster discarded this way). "Injection Fairy Lily" then destroys "Spirit Ryu", but Kaiba wanted this to happen as he needed to make Leichter's Life Points low enough for him to destroy "Injection Fairy Lily" without a problem.
In the first above-mentioned episode, this card appears in a flashback explained by Leichter when he reminds Seto that his birthday gift from Gozaburo Kaiba was where all the mistakes made by Seto himself began.
In the second above-mentioned episode, this card appears in a flashback Leichter has when he explains to Seto that his treachery began when Gozaburo gave him a large amount of dollars to test Seto's business skills.
In episode 186, Yami Yugi uses this card during his Duel against the KC DuelTek 760 while the former was using Rick's Deck. He draws this card and five other Dragon-type monsters via the effect of "Heart of the Underdog". Yugi later discards this card and the five other Dragon-type Normal Monsters that he drew, so that "Spirit Ryu" would gain 1000 ATK for each Dragon discarded.
