Card Appearances:Guardian Elma
- In episode 174, Rafael uses this card during his Duel against Yami Yugi. He was able to summon this card since "Butterfly Dagger - Elma" was on the field. Rafael then uses this card's effect to equip the "Guardian Shield" in his Graveyard (it was there because Rafael previously discarded it through the effect of "Guarded Treasure") to this card, increasing its DEF by 300. Rafael then uses "Backup Gardna's" effect to equip "Butterfly Dagger" to this card instead, increasing its ATK by 300 and decreasing the ATK of "Backup Gardna" to its original value. This card then attacks and destroys "Queen's Knight". "Guardian Grarl" then attacks and destroys "King's Knight". Later Yami Yugi's Kuribabylon attacks "Guardian Grarl" (Whose ATK was 1000 due to it being affected by "Kuriboo's" effect and Yami Yugi destroying "Gravity Axe - Grarl" with "Mystical Space Typhoon"), but Rafael sends "Guardian Shield" to the Graveyard in order to prevent "Guardian Grarl" from being destroyed, but he still takes Battle Damage. Rafael later activates "The Seal of Orichalcos". In the next episode, this card gained 500 ATK due to "The Seal of Orichalcos". Later "Guardian Eatos" attacks "Dark Magician", but Yugi activates "Magical Hats" to hide "Dark Magician" and "Big Shield Gardna" within two of four hats. "Guardian Eatos" then destroys a hat and it's revealed to contain "Big Shield Gardna". This card then attacks and destroys an empty hat. "Guardian Grarl" then attacks another hat, but it's revealed to be empty. Later the darkness in Rafael's heart corrupted him after "Eatos" was destroyed and "Guardian Dreadscythe" was summoned. On Rafael's turn, he activates the third effect of "Guardian Dreadscythe" to destroy all of his other monsters and increase the ATK of "Guardian Dreadscythe" to 5500. In the following episode, Rafael regains control over his emotions when "Dreadscythe" was destroyed. Rafael then activates the effect of "Underworld Circle" to revive "Guardian Grarl". He then activates "Soul Charge" to revive "Backup Gardna", this card, and "Guardian Kay'est" and take 500 damage for each monster revived this way. Since three were revived this way, Rafael takes 1500 damage which wins Yami Yugi the Duel. Rafael did this on purpose so that he could empty his Graveyard until there were no more monsters in it.
- In the second above-mentioned episode, this card appears in a flashback Yami Yugi has when he notes to Rafael his heart was crying when this card was destroyed and he ruthlessly sacrificed his monsters.
- This card appears in the GX Japanese closing song, Borderline Battle.
