Cthulhu

Cthulhu is a cosmic entity first reported by writer H. P. Lovecraft. It was first introduced in his short story "The Call of Cthulhu", published by the American pulp magazine Weird Tales in 1928. Considered a Great Old One within the pantheon of Lovecraftian cosmic entities, this creature has since been featured in numerous popular culture references. Lovecraft depicts it as a gigantic entity worshipped by cultists, in the shape of a green octopus, dragon, and a caricature of human form.

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. Cthulhu is said to resemble a green octopus, dragon, and a human caricature, hundreds of meters tall, with webbed, human-looking arms and legs and a pair of rudimentary wings on its back. Its head is depicted as similar to the entirety of a gigantic octopus, with an unknown number of tentacles surrounding its supposed mouth.
