Cthulhu

Cthulhu is a cosmic entity created by writer H. P. Lovecraft. It was 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 pop 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. It is the namesake of the Lovecraft-inspired Cthulhu Mythos.
