Card Trivia:Fortissimo the Mobile Fortress
- The fortress in this card's artwork also appears in the artwork of "Meklord Astro the Eradicator".
- "Damage Boost", two copies of "Level Cannon", and a very small and faint image of Aporia (merged with this fortress) appear in this card's artwork.
- Fittingly, in Yu-Gi-Oh! 5D's episode 141: "Duel of Despair! Fortissimo the Mobile Fortress!", when this card was activated, Aporia merged with this fortress and later used "Damage Boost" and "Level Cannon" while this card was active.
- This card's name is based on "fortissimo", a musical dynamic that indicates something should be played "very loud."
- Fittingly, the Japanese names of Aporia's three embodiments of despair are named after The Three Tenors, a popular operatic group who originated from Italy.
- This card has a counterpart fused with "Meklord Astro Mekanikle": "Meklord Army Deployer Obbligato".
