Cthulhu (Lovecraft)

"That is not dead which can eternal lie, yet with stranger eons, even death may die."

Cthulhu is a creation of H.P. Lovecraft, first appearing in the story The Call of Cthulhu in 1928. He is one of the main Great Old Ones of the Lovecraft Mythos, a race of alien deities that are comparable to cosmic beings and archdemons in other works of fantasy.

Cthulhu is known for his grotesque appearance and gigantic size, as well as his ability to drive anyone that gazes upon his form to insanity. While he is not the most powerful of Lovecraft's creations, he is one of the most famous, and his name has become associated with evil and Lovecraftian horror ever since the creature was first brought to public attention.

Appearance
Cthulhu's appearance can change from story to story, but he is most often portrayed as a monster of vaguely humanoid shape with a squid-like face and wings. He is also considered terrifyingly large and apocalyptic, being the size of a mountain (or bigger in some accounts). Most descriptions of him stem from statuettes found in the possession of cult members; they are usually around a foot high and depict Cthulhu in a crouching position.

Following
Cthulhu is said to have a world-wide doomsday cult centered in Arabia, with followers stretching across the entire world. The supposedly immortal leaders of Cthulhu's cult are said to reside in the mountains of China. This cult is nihilistic in nature and seeks to awaken the Old Ones and bring about an apocalyptic age of darkness in which, according to some stories, men would be reduced to shouting and killing each other in fits of madness. Cthulhu is also worshipped by the horrific Deep Ones and the Mi-go, other alien beings in Lovecraft's world.

Cthulhu also has numerous "star-spawn" at his disposal; these creatures seem to share his general appearance but are much smaller and less powerful, though the nature of the "star-spawn" and their relationship with Cthulhu is not widely known.

He Waits Dreaming...
In most of the stories, Cthulhu lays dormant deep under the ocean within the sunken city of R'lyeh, but can still influence the world via many telepathic powers and, of course, his many cults and otherworldly minions. It is said that once Cthulhu is fully awakened, he shall rise from the depths and end the world; thankfully for humanity, Cthulhu has yet to do so. However, he came close in the 1920s when a group of sailors came across his sunken city of R'lyeh, which had been brought to the surface by the alignment of the stars. They opened up one of the strange buildings, only for Cthulhu to exit it and attack them. The creature only halted its attack when the sailors used their ship to cut him in half. As they sailed away, they could see Cthulhu reforming into a whole being again. The world would have ended then but for the fact that R'lyeh suddenly sunk as the stars moved out of position. The resulting powerful current not only dragged Cthulhu into the building he had been trapped in, but also closed the door behind him, thus trapping him yet again.

In other fiction
Cthulhu has appeared in pop culture many times:
 * In the online videogame AdventureQuest World, popularly known as AQ, Cthulhu is a major boss called a Chaos Beast, seemingly working for Chaos Lord Iadoa, under the name Kathool, while actually having ulterior motives, and wants the player to defeat him and Iadoa, so he can achieve his goals.
 * In the Grim Adventures of Billy and Mandy episode "Prank Call of Cthulhu", Cthulhu is literally called on a telephone by Billy, and uses him to start sending prank calls to people that turn them into squid monsters. He is seen playing miniature golf.
 * He appeared in the Real Ghostbusters episode "The Collect Call of Cathulhu" as "Cathulhu."
 * He was parodied in World of Warcraft as C'thun.
 * Leela goes on a date with it at the start of Futurama comics #58 story Dummy up which ends in him fighting with Bender and deleting his sense of humor.
 * In the videogame Castlevania: Symphony of the Night, Cthulhu is the name of a minor enemy with a strong fire breath attack and he is seen at the bottom of the Marble Gallery and again in various parts of the Inverted Castle. However, due to localization misplacing, this enemy is originally "Devil" in the Japanese release of the game while the enemy "Malachi" is the representation of the actual Cthulhu. Due to both monsters being minor henchmen for Dracula, technically Cthulhu does not qualify as a Castlevania villain.
 * One of the heavy metal band Metallica's popular songs in their album Ride the Lightning was a song called "Call of Ktulu," obviously referencing the beast. The named is intentionally misspelled due to the belief that if you say Cthulhu's name verbally, he will come closer to you.
 * Another song by Metallica that is inspired by Cthulhu is "The Thing That Should Not Be" from their album Master of Puppets.
 * Cthulhu shows up in Aoi House.
 * Two characters in the horror movie, The Cabin in the Woods, pays a homage on Cthulhu: the Ancient Ones, which are direct homage to him, especially being ancient deities & another one of the monsters bears a striking resemblance to him, as seen in the behind the scenes.
 * Cthulhu will appear in a future Rick and Morty episode considering that Rick, Morty, and Summer fly away from it holding a baby Cthulhu during the opening credits.
 * Cthulhu was the main protagonist in the Indie RPG "Cthulhu Saves The World", where he must do a great deed to get his godly powers once again.
 * When Bart Simpson rides his skateboard across Springfield, Cthulhu picks him up on its tentacles in the opening scene for the episode Treehouse of Horror XXIV. It is also the main antagonist from the story Cthulhu? Gesundheit! which is featured in a comic book The Simpsons Treehouse of Horror #19.
