Card Appearances:Meklord Army of Wisel
- In episode 141, Aporia uses this card during his Ground Duel against Jack Atlas, Leo, and Luna. He Special Summons this card via the effect of "Fortissimo the Mobile Fortress". After Jack Synchro Summons "Red Dragon Archfiend", Leo activates "Power-Up Adapter" to equip it onto "Morphtronic Staplen" and increase the ATK of "Red Dragon Archfiend" by the ATK of "Morphtronic Staplen", but Aporia activates "Power Gravity" to equip the latter to this card, decrease the ATK of "Red Dragon Archfiend" to 0, and increase this card's ATK by the amount "Red Dragon Archfiend" would have gained. On Aporia's next turn, this card attacks and destroys "Red Dragon Archfiend". After "Meklord Army of Skiel" attacks and destroys "Armored White Bear" (whose DEF was halved due to the effect of "Meklord Army of Granel"), Aporia activates this card's effect, allowing "Meklord Army of Skiel" to inflict piercing damage to Luna. In the next episode, "Power Gravity" is destroyed during the End Phase due to its last effect. This decreases this card's ATK to its original value. Later "Meklord Army of Skiel" attacks "Clock Resonator", but Leo activates "Block Lock" to redirect the attack to "Morphtronic Staplen". Due to the effect of "Morphtronic Staplen", it is not destroyed by battle, but Aporia activates this card's effect to allow "Meklord Army of Skiel" to inflict piercing damage to Leo. After that happens, the second Defense Position effect of "Morphtronic Staplen" switches "Morphtronic Staplen" to Attack Position and switches "Meklord Army of Skiel" and "Meklord Army of Granel" to Defense Position (which decreases the ATK of "Meklord Astro Dragon Asterisk" to 1800). This card then attacks and destroys "Morphtronic Staplen". The Attack Position effect of "Staplen" then activates, decreasing this card's ATK by 300 (which decreases the ATK of "Asterisk" by 300). In the following episode, this card remained on the field until the Duel was over.
- In episode 153, this card appears in a series of flashbacks Leo has when he notes that it was because of Yusei Fudo and Jack that he was able to gain the feelings of never giving up until the very end.
