Cthulhu is a creation of famed horror author H.P. Lovecraft, first appearing as the main antagonist in the 1928 story, The Call of Cthulhu​. He is one of the primary Great Old Ones of Lovecraft's Cthulhu Mythos, a race of alien deities that are comparable to cosmic beings and archdemons in other works of fantasy, and is the titular character of the Cthulhu Mythos. Cthulhu is infamously known for his grotesque appearance and gigantic size, as well as his ability to drive any human that gazes upon his form to insanity.
