- The Warrior-Type monster shown on top of the Machine-Type monster, "UFOroid", is "Elemental HERO Tempest", which is appropriate, because the first Warrior to become "UFOroid Fighter" was "Elemental HERO Tempest" in the anime. The combined original ATK of "Elemental HERO Tempest" and "UFOroid" is 4000.
- It could be argued that this is GX's equivalent to "Dark Flare Knight" or "B. Skull Dragon" because it is the Fusion Monster of the main characters' cards, ("Elemental HERO Tempest" according to the anime), and his best friend's card ("UFOroid").
- This card shares more similarities with "B. Skull Dragon", as both monster made their debut appearance in a duel against the Paradox Brothers.
- This is the Machine-Type equivalent of 2 Fusion Monsters.
- "Dragon Knight Draco-Equiste": A Dragon-Type whose Fusion Materials require "1 Dragon-Type Synchro Monster + 1 Warrior-Type monster".
- "Elemental HERO Neos Knight": A Warrior-Type whose Fusion Materials require ""Elemental HERO Neos" + 1 Warrior-Type monster".
- Though not a required Fusion Material Monster, this card was released before "Elemental HERO Tempest" was, making it the first Fusion Monster to be released before a Material used to summon it.
