In episode 16, this card is shown in a flashback Seto Kaiba has when he explains to Yugi what happened at the Intercontinental Tournament in New York City. Sam was shown using this card during his Duel against Bandit Keith (it was originally Maximillion Pegasus vs. Bandit Keith, but Pegasus later wanted Sam to duel in his place as he wanted to prove that a child can beat Keith). After Keith Normal Summons "Garnecia Elefantis", his opponent summons this monster, which causes Keith to lose. How it happened is unknown due to this monster having 550 less ATK than "Garnecia Elefantis".
It is possible that the flashback tournament played by a set of "Attribute rules". Flying Elephant was a WIND monster, which could defeat EARTH monsters like "Garnecia Elefantis". But how it depleted Bandit Keith's life points to 0 remains unknown as well.
This card can also be seen in Kaiba's briefcase when he takes out a Duel Disk from his briefcase and tosses it to Joey Wheeler.
In episode 108, 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 episode 109, 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.
