The Lunarvilles are nearly-independent cities on Luna, where humans live and work. As of 2068, there were seven of these, all of which were under the administrations of "lunar controllers."

In 2068, in an unsuccessful attempt to bring themselves closer to Earth and facilitate their war of nerves, the Mysterons took over the controller of Lunarville Seven and built a complex in crater 101 of the Humboldt "Sea" of Luna. But Captain Scarlet, Captain Blue, and Lieutenant Green successfully destroyed the complex, and deprived its component matter of the capability of self-reversal, not too long afterwards in the same year.
