• In episode 25, this card appears in a flashback Kite Tenjo has when he notes the nearby auditorium building is where the memory of the fourth "Numbers" took place.
  • In episode 45, Nelson uses this card during his Duel against Nistro. He Special Summons this card via "Change to Jet Iron". Due to this card's first effect, its ATK becomes 8000 (which is equal to the combined ATK value of the monsters Tributed for the activation of "Change to Jet Iron". This card then attacks and destroys one of the weaker "Heroic Challenger - Spartan", but Nistro activates "Heroic Guard" to Tribute the "Heroic Challenger - Spartan" with 4800 ATK and gain Life Points equal to its ATK before the damage is subtracted from his Life Points. Nistro then activates "Heroic Retribution Sword" to equip it to the remaining "Heroic Challenger - Spartan" and target this card. Nistro explains that if "Heroic Challenger - Spartan" battles this card, the second effect of "Heroic Retribution Sword" will destroy this card and Nelson will take damage equal to its ATK. Nelson then activates this card's second effect to Tribute itself and revive "Esper Star Sparrow", "Beast-Warrior Puma", "Phoenix Beast Gairuda", and "Ironhammer the Giant". As this card left the field, "Heroic Retribution Sword" is destroyed due to its last effect.
