Cthulhu is a fictional cosmic being introduced by H. P. Lovecraft in his 1928 short story "The Call of Cthulhu", first published in Weird Tales, apart of the wider Cthulhu Mythos. Portrayed as a powerful, octopus-like Great Old One, Cthulhu is said to dwell in a death-like sleep within the sunken city of R'lyeh beneath the Pacific Ocean. As the central figure and namesake of the Cthulhu Mythos, he has become one of Lovecraft’s most iconic creations, later appearing in various works by other authors and becoming a prominent figure in popular culture.
Cthulhu’s physical form is most frequently described through depictions found in statues and idols. One such sculpture, created by the artist Henry Anthony Wilcox following a series of disturbing dreams, portrayed the being as a hybrid of octopus, dragon, and man, with a bulbous, tentacled head, a grotesque, scaly torso, and small, wing-like appendages. Another idol, discovered during a police raid on a cult, depicted a vaguely humanoid figure with an octopus-like head, a rubbery, scaled body, sharp claws, and narrow wings.
Cultists of Cthulhu and his kind—referred to as the Great Old Ones—believe that their power is tied to the positions of the stars. When the stars are aligned correctly, these entities are said to awaken and spread across the cosmos. When the stars are misaligned, they lie dormant, not dead but suspended in a deathless slumber maintained by Cthulhu’s powerful spells.
The only direct account of Cthulhu’s living form comes from the sailor Gustaf Johansen, a survivor of an expedition that briefly encountered the risen city of R’lyeh in 1925. He describes Cthulhu as a towering, gelatinous green mass with immense flabby claws, a cephalopod-like head, and writhing facial tendrils. The creature’s sheer scale led Johansen to remark that it was as though “a mountain walked or stumbled.” His account is echoed by Wilcox’s dreams, which spoke of a “gigantic thing” miles tall, lumbering across alien landscapes.
Johansen recalls that two of his crew died from sheer terror upon seeing the monster, while others were physically seized by its enormous claws. One man vanished within an impossible architectural anomaly of R’lyeh, described as a non-Euclidean angle. The ordeal ended with the death of William Briden, who lost his mind after witnessing Cthulhu chasing their ship and succumbed to madness soon after.

Cthulhu is described as an alien entity who arrived on Earth during the Paleozoic era, accompanied by his Star-Spawn.
The classification of Cthulhu within the mythos varies between sources. In one quote from the Necronomicon, he is referred to as a "cousin" to the Old Ones, though he is said to perceive them only faintly. In this context, "Old Ones" refers specifically to beings of Yog-Sothoth’s kind, suggesting a familial connection but a clear difference in nature. The Call of Cthulhu roleplaying game reflects this distinction by listing Cthulhu as a Great Old One, while Yog-Sothoth is classified as an Outer God.
In At the Mountains of Madness, explorers in Antarctica discover the ruins of a city built by the Elder Things, crinoid-like beings who once waged war with Cthulhu and his spawn. Notably, these Elder Things are the ones referred to as "Old Ones" or "Great Old Ones" in this narrative. The explorers decipher a visual history from carvings, revealing that Cthulhu's race came from the stars and initially forced the Elder Things into the sea. A truce was eventually reached, allowing Cthulhu's kind to inhabit newly formed landmasses, while the Elder Things retained dominion over the oceans. However, when the Pacific landmasses later sank, they took the city of R’lyeh and Cthulhu’s spawn with them, allowing the Elder Things to reestablish their supremacy.
One of the expedition members, William Dyer, remarks on the Star-Spawn’s strange and unfamiliar matter, which differs even more from known earthly substances than that of the Elder Things. He observes that Cthulhu’s kind were capable of undergoing transformations that their enemies could not, implying that they originated from even farther regions of the cosmos. Dyer also speculates that the Elder Things may have devised a cosmic mythology to explain their occasional defeats, though this framework appears in the narratives of their enemies as well.
Other sources hint at two mythic cycles—the Yog-Sothoth and Cthulhu traditions—predating humanity’s arrival on Earth. (HPL: The Whisperer in Darkness) In this tale, the alien Mi-Go are said to revere Cthulhu and possibly share a similar unknown material composition with his spawn. The narrative also links Cthulhu’s arrival to the appearance of certain historical supernovae—or possibly metaphorical "stars", such as influential individuals—stating: "I learned whence Cthulhu first came, and why half the great temporary stars of history had flared forth." Some humans are said to call the Mi-Go "the old ones", adding further confusion to the terminology.
Investigations into the Esoteric Order of Dagon in Innsmouth revealed that the Deep Ones also worship Cthulhu. Although a 1928 government raid suppressed their activity, Robert Olmstead believed they would eventually return to continue offering sacrifices to Cthulhu, claiming that the next uprising would involve a city even greater than Innsmouth. (HPL: The Shadow Over Innsmouth)
A possible earlier incarnation of Cthulhu appears in Robert E. Howard’s Skull-Face under the name Kathulos, a sorcerer from Atlantis. Lovecraft affirmed that Kathulos and Cthulhu were the same entity. (HPL: Selected Letters 3.421, The Whisperer in Darkness) In the story, Kathulos is portrayed as a "Son of the Ocean" who possesses hypnotic powers and commands a worldwide network of followers. The term "tentacles" is often used metaphorically to describe the reach of his influence.
Appearance
General Description:
Cthulhu is depicted as a squat, monstrous being with a grotesque, vaguely humanoid form. Its posture is hunched, and it appears perched or seated atop a stone pedestal etched with strange runes.
Facial Features:
The creature has a bulbous, octopus-like head with numerous thick tentacles hanging from its lower face, obscuring its mouth. Its eyes are wide and dark, conveying an unblinking, alien stare.
Clothing/Outfit:
None. The creature is entirely nude, its body covered in rough, scaled textures.
Special Features:
Cthulhu’s most distinctive features include its cephalopod-like head, its draconic wings protruding from its back, and clawed limbs. The sketch includes non-human text or symbols carved into the base beneath it, implying arcane or alien origins.
Personality
Apathetic and Alien: Cthulhu exists beyond the comprehension of mortals, its mind alien and detached from human concepts of morality or civilization. It is indifferent to human suffering or welfare, viewing humanity as a fleeting curiosity or as tools to further its own return.
Harbinger of Anarchy and Madness: Cthulhu embodies a vision of cosmic anarchy, where the structures of human morality and law dissolve into primal chaos. Its presence encourages the shedding of conventional ethics, inviting madness and violence in a delirious celebration of existence free from constraint.
Catalyst of Liberation: While monstrous, Cthulhu’s influence promises a kind of freedom—albeit one that is savage and unrestrained. In the age of its return, humanity would cast aside inhibitions and embrace a wild, lawless ecstasy.
Worshipped but Indifferent: Though revered by cultists who echo its ancient ways and prophecies, Cthulhu does not reciprocate devotion. Worshippers are mere echoes of its distant, timeless power, keeping alive the promise of its return without any true understanding of its motives.
Embodiment of Cosmic Freedom: Ultimately, Cthulhu personifies a freedom unbound by human limitation—a freedom that strips away reason and sanity in favor of primal instinct and boundless, joyous violence.
Relationships
Cthulhu's Cult
The size and structure of Cthulhu’s cult are not clearly known, though it is widely spread, with numerous cells operating across the globe. Its members are known for repeating an iconic chant: "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn," translated as "In his house at R'lyeh, dead Cthulhu waits dreaming." A common shortened form, "Cthulhu fhtagn," is often interpreted to mean "Cthulhu waits," "Cthulhu dreams," or "Cthulhu waits dreaming." This phrase is believed to be in R’lyehian, a language said to have been brought to Earth by Cthulhu’s Star-Spawn.
The cult of Cthulhu is described as having a global presence, with central activity in Arabia and additional followers in remote places such as Greenland and Louisiana. Reports also mention immortal leaders dwelling in the mountains of China. Within the faith, Cthulhu is referred to as the high priest of the Great Old Ones—ancient entities that arrived on Earth from the cosmos before the existence of humankind.
Worship of Cthulhu does not exclude devotion to other cosmic beings. The famed occultist Abdul Alhazred, for instance, is said to have venerated both Cthulhu and Yog-Sothoth. Cultists believe that when Cthulhu and his kin return, humanity will be transformed into beings like them—rejecting order and morality in favor of chaotic celebration and violence. They anticipate being taught new ways to indulge in ecstatic destruction, ultimately leading to a planet consumed by frenzied freedom.
The cult has been implicated in ritual sacrifices, although some detained members have claimed the actual acts were carried out by entities referred to as the Black Winged Ones. These beings are distinct from the Star-Spawn, and little is known about their true nature or their connection to Cthulhu.
In addition to human worshippers, the aquatic beings known as the Deep Ones also venerate Cthulhu. Like their human counterparts, they are known to perform sacrificial rites in his name. While they also revere Father Dagon and Mother Hydra, the nature of these figures’ relationship to Cthulhu is unclear. Some later interpretations, such as those by Lin Carter, suggest Dagon and Hydra may serve Cthulhu.
The K’n-yanian species, a subterranean humanoid race, also revere Cthulhu—whom they call Tulu—alongside the deity Yig. According to their traditions, Cthulhu transported them to Earth from the stars. They also venerate a substance known as Tulu-metal, a mysterious alien material believed to have been brought by Cthulhu.
Other alien species in the Mythos are associated with Cthulhu as well. The Mi-Go, along with their human followers, are recorded as invoking "Great Cthulhu" in religious ceremonies. Another race, the Fishers from Outside, may also have ties to Cthulhu (referred to as Clulu) and the deity Tsathoggua, as suggested by relics found in the African wilderness.
After Johansen rammed the Alert into Cthulhu, the creature's body ruptured like an "exploding bladder" and turned into a "blinding green cloud," which soon began to reform itself.
Shapeshifting
In At the Mountains of Madness, the artwork of the Antarctic Elder Things shows that the Star-Spawn of Cthulhu (and presumably Cthulhu himself) are composed of a type of matter unlike anything on Earth. This matter allows them "to undergo transformations and reintegrations" that are impossible for life forms made of traditional matter, such as the Elder Things.
Psychic Abilities
Castro, a Cthulhu cultist, reports that the Great Old Ones are telepathic and "knew all that was occurring in the universe." They communicated with the first humans by "moulding their dreams," thereby establishing the Cthulhu Cult. After R'lyeh sank beneath the waves, "the deep waters, full of the one primal mystery through which not even thought can pass," cut off this spectral communication.
It is important to note that the "Great Old Ones" Castro refers to correspond only to the Star-Spawn of Cthulhu, not to other entities called Great Old Ones elsewhere in the Mythos. This is supported by Castro's claim that "They all lay in stone houses in Their great city of R'lyeh." In the story, Cthulhu is also identified as the "priest" of the Great Old Ones.
When a portion of R'lyeh, believed to be Cthulhu's citadel, briefly surfaced in 1925, Cthulhu's influence was felt worldwide by psychically sensitive individuals. Artists and asylum patients were particularly affected. Globally, there were "cases of panic, mania, and eccentricity," including suicides.
Death-like State
Most sources agree that Cthulhu and his Star-Spawn currently exist in a death-like dormant state, possibly akin to suspended animation, aestivation, or hibernation. They cannot awaken without external assistance from their cultists. Rituals to release them may involve opening dimensional gateways, as suggested in The Trail of Cthulhu series. It is often assumed they can only return to life when "the stars are right."
This state between life and death is reflected in Lovecraft's statement that "dead Cthulhu waits dreaming," and poetically expressed in the couplet by Abdul Alhazred:
"That is not dead which can eternal lie,
and with strange aeons even death may die."
Other
Standard Tactics: Cthulhu speaks to people in their dreams to convert them within its cult to have them prepare the ceremony of resurrecting him.
Upon being removed from this state, Cthulhu goes around attacking with his claws, his mere existence can also send madness and fear that results in death in beings that cannot grasp his form.

Trivia
Despite the name of the mythos, Cthulhu is not the main cosmic entity within it and it is actually one of the lower hierarchy as can be seen within the family tree.
↑Weird Tales Volume 11 Issue 2 "The Call of Cthulhu": ""Of such great powers or beings there may be conceivably a survival . . . a survival of a hugely remote period when . . . consciousness was manifested, perhaps, in shapes and forms long since withdrawn before the tide of advancing humanity . . . forms of which poetry and legend alone have caught a flying memory and called them gods, monsters, mythical beings of all sorts and kinds. . . ." —Algernon Blackwood."
