- The warrior shown on top of the machine is "Elemental Hero Tempest", which is appropriate, because the first warrior to become "UFOroid Fighter" was Tempest in the anime. If you add the attack of Tempest and UFO, the sum is 4000.(2800(Tempest)+1200(UFO)= 4000)
- It could be argued that this is GX's first documented Joint Fusion because it is the fusion of the main character's card (Tempest according to the anime) and his best friend's card (UFOroid).
