Chariots of death for the female silver-draped aliens, the Kilaak UFO has the ability to generate a wall of heat, thereby incasing the spacecraft in a living sheet of flame. A flying projectile that can destroy anything it touches. However, with all their ingenuity, the aliens underestimated the will of human kind. As Godzilla ripped into the exterior of their base, dropping the temperature and forcing the Kilaakian into hibernation, the SY3 hunted down and destroyed the last saucer of the alien race.

Having their trump card, King Ghidorah, get slain by several other Earth monsters, the Kilaakian tried a last ditch effort. Threatening humankind that the "Fire Dragon" would blaze a path of death across their cities, the Kilaakian strived for control again. As a show of power, the aliens sent the flaming mass against the terrestrial kaiju. Rodan was sent in retreat as Godzilla fired his beam into the creature. However, not even his might could stop the "Fire Dragon". Sending their rocket ship, the Moonlight SY3, the humans launched an all out assault with freezing missiles against the Kilaak monster. However, during the battle, it was evident that the "Fire Dragon" was nothing more than a Kilaak UFO incased in a barrier of flame. Finding the truth, it was not long before they dispensed with the craft, ending the Kilaak threat forever.
