  • In episode 45, Nelson uses this card during his Duel against Nistro. After Nistro activates the effect of "Heroic Challenger - Spartan" to make it gain ATK equal to the ATK of all other face-up copies, Nelson activates "Change to Jet Iron" to Tribute this card, "Esper Star Sparrow", "Phoenix Beast Gairuda", and "Ironhammer the Giant" in order to Special Summon "Dimensional Jet Iron". After Nistro equips "Heroic Retribution Sword" to "Heroic Challenger - Spartan", Nelson activates the second effect of "Dimensional Jet Iron" to Tribute itself and revive this card, "Esper Star Sparrow", "Phoenix Beast Gairuda", and "Ironhammer the Giant". Later "Heroic Challenger - War Hammer" attacks and destroys this card. Nistro then activates the effect of "War Hammer" to equip this card to it and increase its ATK by this card's ATK. Later Nelson activates the effect of "Superdimensional Robot Galaxy Destroyer" to destroy all of Nistro's Spells and Traps, which returns the ATK of "War Hammer" to its original value.
    • This card also appears in a flashback Astral has when he recognizes this card and his fellow comrades used by Nelson. Astral states that recalling that match makes his heart be filled with joy.
