Cthulhu Mythos
Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn.
In his house at R'lyeh dead Cthulhu waits dreaming.
~ H.P. Lovecraft, The Call of Cthulhu


Cthulhu is an godlike alien entity of epic proportions. He is considered a Great Old One within the pantheon of Lovecraftian cosmic entities. While the Great Old Ones are not truly all-powerful gods as the Outer Gods are, they are nonetheless terrifying and godlike in mortal eyes. Originally from another universe altogether, Cthulhu and his kin arrived on earth billions of years ago filtering down from the stars. However, the planet had already been claimed by a species known as the Elder Things, leading to a war between Cthulhu's Star Spawn and the Elder Things' Shoggoth monstrosities. Eventually, an uneasy peace was reached and the two factions each claimed their own half of the world.

During this time, Cthulhu constructed the city of R'lyeh, a place composed of structures so complex, the human mind would be unable to fathom them. However, a change in the stars caused Cthulhu to fall into a deep slumber, his city, and the majority of his race sinking to the bottom of the ocean with environmental changes. Though the Elder Things' only adversaries had vanished, their victory was cut short when the Shoggoth slaves gained sentience, rebelling, and destroying them. With the masters of the old world gone, life evolved from the Elder Things' leftover experiments, and the war was forgotten with time. However, Cthulhu still lies dormant at the bottom of the sea, immune to the changing of the universe. Cults devoted to him can still be found at the darkest corners of the earth, whispering dark blasphemies that one day, when the stars are right, the sunken city will rise and its lord shall return to claim what is his.

Powers and Stats

Tier: Unknown

Name: Cthulhu, High Priest of the Great Old Ones, The Great Dreamer, The Sleeper of R'lyeh

Origin: Cthulhu Mythos

Gender: Genderless, referred to as Male

Age: Vigintillions of years old (It is implied that he has not been able to draw on his full power due to the stars not being right for vigintillions of years)

Classification: Great Old One, Alien Deity

Powers and Abilities: Superhuman Physical Characteristics, Immortality (Types 1, 3, 4, 5 and possibly 9), Regeneration (At least Low-Godly), True Flight, Telepathy, Dream Manipulation, Magic, Fear Manipulation (Can induce massive amounts of fear in people by spreading it through their dreams), some degree of Reality Warping (It created a city out of nowhere, and in that city, reality is strange and warped), possible Higher Dimensional Manipulation (The geometry of R'lyeh appears impossible and simply "all wrong" to humans who see it in their dreams), Shapeshifting, Plasma physique and manipulation, Mind Manipulation, Madness Manipulation (Type 3; Mortals are driven insane from the act of looking at Cthulhu's form), can travel between universes, Large Size (Type 3; stated to be miles high)

Attack Potency: Unknown

Speed: Massively FTL+ (He and his kin originally came from another space-time continuum, presumably the same one as the Mi-go. Like other lesser Great Old Ones, he should be capable flying between star systems without issue)

Lifting Strength: At least Class T due to its sheer size (He is as tall as a mountain)

Striking Strength: Unknown

Durability: Unknown. Its immortality and regeneration make it incredibly hard to kill. It should also be noted that Cthulhu and the other Great Old Ones are apparently not made of matter, but something else entirely. Thus, it can be assumed any damage to their physical forms is purely superficial.

Stamina: Extremely High

Range: At least Planetary (Cthulhu can mentally interact with anyone on the planet). Apparently Universal when not hindered (The Great Old Ones were said to know and influence all that happened in the universe before they were sealed away/began to slumber)

Standard Equipment: None, though he does have an army of Star Spawn at his disposal. Star Spawn apparently appear to look similar in appearance to Cthulhu himself, albeit smaller to varying degrees. Their capabilities are unknown, though they did wage war with the incredibly advanced Elder Things billions of years ago.

Intelligence: Nigh-Omniscient (According to Old Castro, Cthulhu, and the other Great Old Ones know all that is occurring in the universe due to being able to telepathically communicate with and control any sentient beings, regardless of location. However, from his sunken city, Cthulhu's reach is restricted by some "primal mystery" in the waters, allowing him only to know everything that is transpiring on earth)

Weaknesses: Unknown

Notable Attacks/Techniques:

  • Telepathy: Cthulhu has massive telepathic abilities that enable him to speak to individuals or groups of beings whether, in their subconscious or conscious mind, this also enables him to devastate minds of mortals, though he may be able to apply this to immortal creatures.
  • Mindmash: When mortals look at Cthulhu, they will go insane.
  • Unconventional Composition: Cthulhu's body is composed of an unknown material similar to plasma, it is described as "tenebrous", "slobberingly", "gelatinous", and "greasily", giving him an incorporeal quality, as such he is capable of withstanding solar heat, as well as shapeshifting into the three states of matter: Solid, Gaseous, and Liquid. The mere fact that this full physical form is (presumably) in another plane of reality makes this body undying and virtually immortal.

Note: It has been decided that the High 4-C Rating for Great Old ones is invalid due to being a semantic misinterpretation. More can be explained here.
