Mi-go
Mi-go are a fictional race of extraterrestrials created by H. P. Lovecraft and used by others in the Cthulhu Mythos setting. The word Mi-go comes from "Migou", a Tibetan word for yeti. The aliens do not actually resemble yeti, and are instead fungus-based lifeforms that look like winged humanoid crabs.
Mi-go are first named as such in Lovecraft's short story " The Whisperer in Darkness" (1931). However this is considered an elaboration on earlier references in his sonnet cycle Fungi from Yuggoth (1929–30) to descriptions of alien vegetation on dream-worlds.
The Mi-go have appeared across a range of media set in the Cthulhu Mythos.
