• In episode 195, Zigfried drops this card after he lost his Duel against Kaiba.
    • It is odd that this card was in Zigfried's hand as he had no cards in his hand at that point.
  • In episode 196, Zigfried gave this card to his brother Leon von Schroeder for his Duel against Yugi Muto.
    • This card is also shown within Leon's backstory flashback when he explains how he became fascinated into Duel Monsters after discovering the game.
      • There are strangely multiple copies of this card shown during this flashback even though there should only be one copy.
  • This card was a prototype, but was never completed, so Zigfried hacked into KaibaCorp and altered the text and effect of the card as well as ensnare it with a virus that would destroy all files in the KaibaCorp mainframe.
  • In episode 197, Leon uses this card during his duel against Yami Yugi. After this card is activated, Leon activates this card's first effect to Special Summon "Cinderella". Later Leon found out that this card was not legal until his brother made it so through tampering and that he just activated a virus that was destroying all files in the KaibaCorp mainframe. Leon then activates "Mystical Space Typhoon" to destroy this card, but it didn't work. In the next episode, this card forces "Dark Magician Girl" to attack "Pumpkin Carriage". This card's fourth effect then activates, destroying "Dark Magician Girl" and inflicting damage to Yami Yugi equal to half of its total ATK. On Leon's Standby Phase, Yugi was forced to send half of his deck to the Graveyard as per this card's Maintenance Cost. Leon then activates this card's first effect to Special Summon "Forest Wolf". This card then forces "Cinderella" to attack directly. "Forest Wolf" then attacks directly, but Yugi activates "Dark Magic Retribution" to revive "Dark Magician Girl" and use it to intercept the attack. "Dark Magician Girl" then destroys "Forest Wolf". Later Yami Yugi activates the effect of "Royal Straight Slasher" to destroy all cards on Leon's side of the field. Although "Iron Hans", "Pumpkin Carriage", "Cinderella", and "Glass Slippers" were destroyed, this card wasn't due to its own effect. On Leon's next Standby Phase, Yugi revealed he had only one card left in his Deck which made it impossible to pay the Maintenance Cost for this card. As a result, this card was destroyed and the virus that this card created in the KaibaCorp mainframe stopped.
    • In the first above-mentioned episode, this card appears within a flashback Leon has when he remembers Zigfried giving him this card.
