Kilaak

The Kilaaks, also referred to as Kilaakians, were a species of sentient alien which appeared in Toho Studios' creature feature Destroy All Monsters.

Description
In their natural state, Kilaaks resembled small metallic maggot-like creatures, but they usually employed a device to make them appear as humanoid females. However, exposure to extreme cold would cause them to involuntarily drop this disguise. A highly technologically-advanced race, they were capable of creating machinery such as interplanetary spacecraft and mind-control devices. The Kilaaks hailed from Planet Kilaak, a world unknown to humans which rested in the asteroid belt between Mars and Jupiter.

History
The Kilaaks invaded Earth as part of their plan to create a civilisation with greater scientific potential. As part of this scheme, they established a secret base on the moon from which they employed their mind control technology to command the monsters of Earth - including Godzilla, Kumonga, Manda, Mothra and Gorosaurus - to attack major cities around the world.

Luckily, human scientists managed to locate their moon base and destroy it, after which the monsters were returned to their senses. In an effort to salvage their plan, the Kilaaks called upon their ally, the mighty King Ghidorah, to aid them, but the combined power of Earth's monsters was enough to see this threat off.

Subsequently, the King of the Monsters found and destroyed the Kilaaks secret base on Earth, and they were never heard from again.
