Card Trivia:Fortissimo the Mobile Fortress
- This card's artwork also appears in the artwork of "Meklord Astro the Eradicator".
- Two copies of "Level Cannon" and a "Damage Boost" can be seen in the artwork of this card.
- Aporia appears in this card's artwork, merged with the fortress. He can be seen as a very small human image just below the middle circle on the top part of the artwork.
- In this card's appearance in the Yu-Gi-Oh! 5D's anime, Aporia is able to merge with the card, something that has only been done with monsters in the anime prior, specifically "The Winged Dragon of Ra" and "Malefic Truth Dragon".
- The egg-like structure in the center of the card resembles the cores of the "Meklord Emperor" monsters, specifically "Wise Core".
- The "Fortissimo" in this card's name is named after the musical dynamic of the same name, which is Italian for "very loud". This is fitting, as 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".
- This is the third "the Moving Fortress" card, after "Stronghold the Moving Fortress" and "Gear Golem the Moving Fortress".
- However, this card is the only one whose TCG name is not "Moving Fortress", being "Mobile Fortress" instead.
- This card's effect is similar to the secondary effect of "Sargasso the D.D. Battlefield". Both cards are Field Spell Cards used by antagonists in their respective series that inflict effect damage during the End Phase if certain monsters are/are not on the players' field (i.e., this card if the player does not control a Machine-Type monster, and "Sargasso" if the player controls an Xyz Monster).
