The Kilaaks (キラアク星人 are a race of aliens which serve as the main antagonists of the 1968 film Kirāku Seijin, lit. "Planet Kilaak People")Destroy All Monsters. They hail from Planet Kilaak, an undiscovered planet somewhere within the asteroid belt.
The Kilaaks' Japanese name simply translates to "Kilaak Aliens," or more literally "Planet Kilaak People." Toho's English export trailer for Destroy All Monsters uses the spelling "Kilaacs," a possible indication of its originally-intended translation, although the October 1968 issue of UniJapan Film Quarterly refers to them as "beings from the planet Kilaak" and "the Kilaak girls." The 'K' spelling is today the most widely recognized, appearing in various home video releases' subtitle translations. However, the variant "Kilaakians" is also sometimes applied by English-speaking fans, and the Japanese book Godzilla 1954-1999 Super Complete Works gives them the English name Kiraaku.
The Kilaaks take the form of female humans wearing light blue robes that cover all except their faces. However, these forms are actually a disguise, as the Kilaaks' true forms resemble small metallic worms.
The Kilaaks were a race of female humanoids from the planet Kilaak, which was said to be between Mars and Jupiter. The aliens invaded Monsterland and assumed control of the kaiju and resident scientists. Soon the monsters were attacking cities across the globe - Godzilla attacked New York City, Rodan assaulted Moscow, Mothra invaded Beijing, Manda attacked London, and Gorosaurus destroyed Paris. Despite the military's efforts to stop them, the aliens remained unscathed until their base on the moon was destroyed by the rocketship, Moonlight SY-3. When humanity broke the kaiju from their control, the aliens pulled out their trump card - King Ghidorah. However, up against the combined might of Godzilla, Anguirus, Gorosaurus, Rodan, Mothra, Kumonga, and Minilla, Ghidorah was easily slain. Godzilla then destroyed the Kilaaks' base on Earth, ending their threat.

The Kilaaks attempted to conquer Earth in order to create a great scientific civilization, which they stated needed some death to create. The aliens thrived in high temperatures and were greatly susceptible to cold. When they were struck by low temperatures, they shed their human guises and reverted to their true forms: small, metallic worm-like creatures. However, in this form, the aliens are almost incapable of moving due to the form's sheer weight.
Aside from their mind control devices (that can enslave both humans and kaiju alike), the Kilaaks don't seem to possess any particularly notable technology, though they do have forcefields that can't be penetrated even by bullets. Their flying saucers aren't much of a threat in and of themselves, but they have the ability to engulf their outer hulls in flames, burning anything the ship may touch. This mode is called a "Fire Dragon."

- The Kilaaks are the second race of aliens to come from a planet somewhere near Mars and Jupiter. The first were the Xiliens, whose homeworld of Planet X is also said to be in the same region.
