Cthulhu
While the origin of Cthulhu is not definitively established, it is suggested that it is the planet Vhoorl,
with his advent somehow connected with stellar phenomena: "I learned
whence Cthulhu first came, and why half the great temporary stars of
history had flared forth". It is also suggested in both "At the Mountains of Madness" and “The Whisperer in Darkness” that Cthulhu is made up of some unknown and foreign matter.
The most detailed descriptions of Cthulhu appear in the short story "The Call of Cthulhu", and are based on the statues of the creature. One, constructed by an artist after a series of baleful dreams, is said to have "yielded simultaneous pictures of an octopus, a dragon, and a human caricature.... A pulpy, tentacled head surmounted a grotesque scaly body with rudimentary wings". Another, recovered by police from a raid on a murderous cult, "represented a monster of vaguely anthropoid outline, but with an octopus-like head whose face was a mass of feelers, a scaly, rubbery-looking body, prodigious claws on hind and fore feet, and long, narrow wings behind."
When the creature finally appears, the story says that the "thing cannot be described", but it is called "the green, sticky spawn of the stars", with "flabby claws" and an "awful squid-head with writhing feelers". The phrase "a mountain walked or stumbled" gives a sense of the creature's scale.
