The Fire Dragon is a Kilaak UFO and a supporting antagonist of Destroy All Monsters.
While flying around its lunar base, the Moonlight SY-3 sighted a Kilaak UFO flying around the moon.
After Godzilla and the other monsters defeated King Ghidorah, a Kilaak UFO, identified as a kaiju called the "Fire Dragon", emerged from the Kilaak base. The ship caught Rodan on fire and flew around, destroying a building as well as some planes. However, Godzilla was able to find their base and so ripped into it, dropping the base's temperature and having the Kilaaks be forced into hibernation. Shortly afterwards, the SY3 found and took down the last one of the Kilaaks' spacecraft.
- The Fire Dragon can create a lot of heat, covering itself in flames. Like this, the spaceship can ravage anything in its path. This fire is strong enough to even set kaiju such as Rodan ablaze. When on fire, this mode is referred to as the Fire Dragon.
