This particular monster was created by horror write HP Lovecraft, and they’re called Cthulhu.
Cthulhu is a god like being from another planet. Neither Male or female, Ancient and forboding.
Cthulhu is infamously known for his gigantic size and grotesque appearance, as well as his capacity to drive any human that looks upon his form to madness.
Cthulhu is High Priest of the great Old Ones, a group of god like monsters who are waiting to rise up and destroy the human race so they can rule the planet.
The Old Ones are neither good or evil, they do not hate humans, they simply do not care about them. They think of humans like ants. Small and inconsequential.
Cthulhu lies in a dream like state in the underwater city of R’lyeh waiting for the time for the Old Ones to rise again. When he fully awakens he will rise from the depths and end the world. Thankfully he has yet to do so… let’s hope he slumbers in peace for all time
