The Mi-go or Fungi from Yuggoth are a race of extraterrestrials spoken of in the Cthulhu Mythos by H. P. Lovecraft and first described in his sonnet cycle "Fungi from Yuggoth" (1929-30). They first became known as "Mi-Go" in Lovecraft's short story "The Whisperer in Darkness" (1931)
The Mi-go are large, pinkish, fungoid, crustacean-like entities the size of a man with a convoluted ellipsoid composed of pyramided, fleshy rings and covered in antennae where a head would normally be. According to two reports, their bodies consist of a form of matter that does not occur naturally on Earth. Interestingly, they are capable of going into suspended animation until softened and reheated by the sun or some other source of heat. They are about 5 feet (1.5 m) long, and their crustacean-like bodies bear numerous sets of paired appendages. They also possess a pair of membranous bat-like wings which are used to fly through the luminiferous aether of outer space. Their wings do not function well on Earth however. Several other races written about in Lovecraft's Mythos have wings like these as well.
The Mi-go can transport humans from Earth to Pluto (Yuggoth) and back again by removing the subject's brain and placing it into a "brain cylinder", which can be attached to external devices to allow it to see, hear, and speak.
The Mi-go previously worshiped the beings Yog-Sothoth, Nyarlathotep, and Shub-Niggurath, among others, although it is acknowledged that the Mi'Go are now at war with the Elder Gods. Their moral system is completely alien, making them seem highly malicious from our human perspective.
One of the moons of Yuggoth holds designs that are sacred to the Mi-go. The symbols inscribed upon the moon are useful in various processes mentioned in the Necronomicon. It is said that transcriptions of these designs can be sensed by the Mi-go, and those possessing them shall be hunted down by the few remaining on earth.
Hastur despises the Mi-go,and his cult, servants of "Him Who Is Not to be Named", are dedicated to hunting them down and exterminating the fungoid threat. However, in the original story a human ally of the Mi-go mentions "Him Who is not to be Named" in the list of honored entities along with Nyarlathotep and Shub-Niggurath. It is possible that their alliance has broken down as of late.
They are distinguished by their mastery in various fields of science, especially surgery. Although they originate from beyond our solar system, they have set up an outpost on Pluto (known as Yuggoth) and sometimes visit Earth to mine for minerals and other natural resources. The Mi-go normally communicate by changing the colors of their orb-like heads or by emitting odd buzzing noises. They can also speak any human language upon receiving the appropriate surgical modification.
