Cthulhu Mythos deities
Writer H.P. Lovecraft created a number of fictional deities throughout the course of his literary career, including the "Great Old Ones" and the "Outer Gods", with sporadic references to other miscellaneous deities (e.g. Nodens). The Elder Gods are a later creation of writers such as August Derleth, who is credited with forming the Cthulhu Mythos.
Great Old Ones 
An ongoing theme in Lovecraft's work is the complete irrelevance of mankind in the face of the cosmic horrors that apparently exist in the universe, with Lovecraft constantly referring to the "Great Old Ones": a loose pantheon of ancient, powerful deities from space who once ruled the Earth and who have since fallen into a deathlike sleep.
Lovecraft named several of these deities; Azathoth, Cthulhu, Ghatanothoa, Shub-Niggurath, Yog-Sothoth, Nyarlathotep and Yig. With the exception of Cthulhu, this loose pantheon apparently dwelled in deep space. Worshipped by deranged human cults, these beings are currently imprisoned (beneath the sea, inside the Earth, and in distant planetary systems) and apparently eagerly await the time of their release. Although Lovecraft did establish this premise in his 1928 short story, The Call of Cthulhu with reference to the eponymous creature, it was Derleth who applied the notion to all of the Great Old Ones.

In Joseph S. Pulver's novel Nightmare's Disciple several new Great Old Ones and Elder Gods are named. The novel mentions T'ith and Xu'bea, The Teeth of the Dark Plains of Mwaalba. Miivls and Vn'Vulot, are said to have fought each other in southern Gondwanaland during the Cretaceous period, whereas Rynvyk has been one of the mates of Cthulhu's sister Kassogtha who bore him three sons (one named Ult), and now rests in a crimson pool in the Hall of Tyryar, somewhere in Norway.
Outer Gods 
The Outer Gods are ruled by Azathoth, the "Blind Idiot God", who holds court at the center of the universe. A group of Outer Gods dance rhythmically around Azathoth, in cadence to the piping of a demonic flute. Among the Outer Gods present at Azathoth's court are Lesser Outer Gods, the entities called "Ultimate Gods" in The Dream-Quest of Unknown Kadath, and possibly Shub-Niggurath, the "Black Goat of the Woods". Yog-Sothoth, the "All-in-One", co-rules with Azathoth and exists at all places and in all times in the cosmos, yet is somehow locked outside the mundane universe. Nyarlathotep, the "Crawling Chaos", is the avatar and soul of the Outer Gods, and serves as an intermediary between the deities of the pantheon and their cults. The only Outer God to have a true personality, Nyarlathotep possesses a malign intellect and reveals a mocking contempt for his masters.
List of Outer Gods 
Aiueb Gnshal 
Aiueb Gnshal (The Eyes Between Worlds, The Child-Minded God) is a mysterious Outer God which has his abode in a forgotten temple located somewhere in Bhutan. He appears as a formless black void with seven pulsing orb-like eyes and is mainly worshiped by ghouls which tribute him a defiled cult described in the mysterious Cambuluc Scrolls of the wizard Lang-Fu, dating back 1295 AD. Peering through the eyes of this god, after a hideous and devastating ritual, allows to see straight into Azathoth's court. It is rumoured that the power of Mongolian warlord Temujin had the favour of Aiueb Gnshal.
Azhorra-Tha is an Outer God imprisoned on planet Mars as it fled from Earth after the imprisonment of the Great Old Ones. Its appearance is that of an insectoid to toad-like squid, but its shape continuously changes emitting an awful buzz. The Mi-Go discovered the prison of Azhorra-Tha millennia after and made everything to not reveal its location to any human being.
The Blackness from the Stars 
The Blackness from the Stars is an immobile blob of living, sentient darkness, torn from the primal fabric of the cosmos at the center of the universe. It is distinguishable in darkness only as vaguely shimmering oily pitch. Although intelligent, it speaks no known language and ignores attempts to communicate.
The Cloud-Thing 
A man-eating, cloudy mass, unnamed Outer God at the court of Azathoth.
C'thalpa (The Internal One) is a huge mass of living, sentient magma, located in Earth’s mantle. She is mother of the Great Old One Shterot and other five unnamed hideous children. The Outer God is served by a race of mole-like humanoid burrowers named Talpeurs.
Cxaxukluth (Androgynous Offspring of Azathoth) is one of the Seeds or Spawn of Azathoth, grown to adulthood and monstrous proportions and power. In appearance, Cxaxukluth resembles something of a cross between Azathoth and Ubbo-Sathla: an amorphous, writhing mass of bubbling, nuclear protoplasmic gel. It normally dwells alone in some unnamed place beyond time and space, unless disturbed or summoned away.
D'endrrah (The Divinity) is sort of blurry female entity of supernatural beauty living inside a dark palace located on Mars' Moon Deimos. She lives in a hall with myriads of mirror altering her actual image, which is that of a tentacled dark abyss. This Mythos entity is somewhat inspired to C. L. Moore's Shambleau, illusionary Martian she-vampires of lust.
Gi-Hoveg (The Aether Anemone) is a cosmic entity manifesting as a gigantic spongy and fleshy mass covered in myriads of eyes and spines. It is said to be the archenemy of the Outer God Uvhash, usually summoned to contrast this deity.
Haiogh-Yai (The Outsider) is a monstrous, amorphous, whirling thing living on a wandering black hole named Vix’ni-Aldru, which also hosts a monstrous city made of titanic blocks at its center. There is served by strange, crawling creatures which resemble worms or lizards.
Huitloxopetl (The Haunter of Dreams) is part of the innumerable spawn of Azathoth but for some reason it has not taken part to the battle between the Outer Gods and the Elder Gods and has chosen to live in Sygroth, a dark-laden galaxy located at the outermost rim of the universe. It usually manifests in dreams. This entity has been introduced in a round-robin story so far composed of 15 or more chapters and probably yet to be finished.
The Hydra 
Ialdagorth (The Dark Devourer) is cousin and servant of Azathoth and appears as black, shapeless, malevolent cloudy thing.
Kaajh'Kaalbh is a lesser Outer God servitor of Azathoth but secluded in a parallel chaotic dimension where everything is instable. The god itself is constantly formed and disrupted and has no true form at all. Anyway whoever attempts summoning this entity needs the aid of a Dimensional Shambler and the deity may manifest in variety of forms, often as an immense lava lake or a vast pool of solidified quicksilver.
Lu-Kthu (Birth-womb of the Great Old Ones or Lew-Kthew) is a titanic, planet-sized mass of entrails and internal organs. On closer examination it appears a wet, warty globe, covered with countless ovoid pustules and spider-webbed with a network of long, narrow tunnels. Each pustule bears the larva of a Great Old One.
An invisible wolf-like fiend similar to Fenrir of Norse mythology (if not coincident). Mh'ithrha (Arch-Lord of Tindalos) is the lord of the Hounds of Tindalos and the most powerful. Although not an actual Outer God as such, its form and awesome powers defy standard classification. Mh'ithra's eternal battle with Yog-Sothoth is said to be legendary.
Mlandoth and Mril Thorion 
Mother of Pus 
A Lesser Outer God composed of slime, tentacles, eyes, and mouths. The Mother of Pus was spawned through an obscene mating between a human and Shub-Niggurath. When summoned to Earth, the Mother of Pus seeks refuge in pools of stagnant, foul water.
The Nameless Mist 
The Nameless Mist (Nyog' Sothep?) is a misty, shapeless thing.
Ngyr-Korath (The Ultimate Abomination or The Dream-Death) is a dark blue-green mist which causes a sense of terror as it approaches. Once close, an eye of flame forms within. It spawned by fission the Great Old One ‘Ymnar and its nemesis is the Elder God Paighon. It may coincide with the entity known as the Magnum Tenebrosum.
Once an Elder God, Nyctelios has been punished by his peers - especially Nodens - for having created a race of foul servitors. He has been permanently banned from the Elder God's olympus and imprisoned beneath the eastern Mediterranean Sea, near Greece, in a dark, basalt-built citadel named Atheron. However the exiled deity is not dead, but just sleeping and one day he will rise again from his abyss manifesting himself as a dark blue, 6-meters tall cyclops-like monstrosity with the bulk of his body entirely covered in crawling worms.
Olkoth (God of the Celestial Arcs) appears as a demoniacal god-like entity able to reincarnate in human bodies as the stars are right (sort of a "Cthulhian" Antichrist). Olkoth may emerge in our dimension through an eyeless, grotesque statue of the Virgin Mary.
Shabbith-Ka appears as a shapeless, roughly man-sized purplish aura, spitting and crackling with powerful electrical arcs. A sense of power, malignancy, and intelligence accompanies it and persons able to gaze at its form long enough can see a rudimentary face or faces within the glowing mass.
Star Mother 
The Star Mother appears as a chunk of yellow-green stone about the size of an infant. Its shape suggests a plump, huge-breasted, faceless female figure. From it extend dozens of pencil-thin root-like strands. It is one of the Larvae of the Other Gods and has no cult, although served by zombie slaves.
Tru'nembra (The Angel of Music) is the name given in Malleus Monstrorum Call of Cthulhu roleplay game guide to the entity described in Howard Philips Lovecraft's novel "The Music of Eric Zahn". It has no shape, but manifests as a haunting music.
Tulzscha (The Green Flame) is the name given in Malleus Monstrorum Call of Cthulhu roleplay game guide to the entity described in Howard Philips Lovecraft's story The Festival. Tulzscha appears as a blazing green ball of flame, dancing with its Lesser Outer Gods at the court of Azathoth. Called to our world, it assumes a gaseous form, penetrates the planet to the core, then erupts from below as a pillar of flame. It cannot move from where it emerges.
Uvhash (The Blood-Mad God of the Void) appears as a colossal, vampiric, red mass of tentacles and eyes. It dwells in the realm of Rhylkos, which matches with the red planet Mars and whoever summons Uvhash witnesses an atrocious doom. It seems having affinities with the star vampires and is rumoured to have been one of mad emperor Caligula's eldritch sponsors too. There is enmity with the Elder God Nodens and the Outer God Gi-Hoveg.
Ycnàgnnisssz is a black, festering, amorphous mass that constantly blasts and erupts violently, spewing out bits of churning lava-like material. It spawned the Great Old One Zstylzhemgni by fission.
A gigantic, bat-winged humanoid with detached eyes, wearing a green robe. This horrible deity sees all time and space as it slowly rotates in the centre of its clearing in the 'Jungle of Kled', in Earth's Dreamlands. Beneath its billowing cloak are a multitude of nightgaunts, suckling and clutching at her breasts. Having a close connection to the Great Old One Bugg-Shash, so should Yibb-Tstll be regarded as a Great Old One - specifically in the Drowners group introduced by Brian Lumley, parasitic alien entities which thrive vampyrizing the Great Old Ones themselves - though in RPG materials she is classed as "Outer God".
Yidhra (The Dream Witch or Yee-Tho-Rah) usually appears as a youthful, attractive, earthly female, though her shape may vary.
Yidhra has been on Earth since the first microorganisms appeared and is immortal. To survive in a changing environment, she gained the ability to take on the characteristics of any creature that she devoured. Over time, Yidhra split herself into different aspects, though each part shares her consciousness.
Yidhra is served by devoted cults found in such widely separated places as Burma, Chad, Laos, Sumer, New Mexico, and Texas. Members of Yidhra's cult can gain immortality by merging with her, though they become somewhat like Yidhra as a consequence. Those who serve her are also promised plentiful harvests and healthy livestock. She usually conceals her true form behind a powerful illusion, appearing as a comely young woman; only favored members of her cult can see her as she actually is.
One of her avatars is Madam Yi, appearing as a human female dressed in beautiful white and black robes which constantly billow on some unseen wind, on which she may hover or fly. Her beautiful face is like the painted face of a porcelain doll and her bloodred lips and closed almond-shaped black eyes are forever frozen on a smooth and bone-white face. Long black hair is braided into a single ponytail. The avatar’s hands both end in very long, razor-like black fingernails.
Yomagn’tho (The Feaster from the Stars, That Which Relentlessly Waits Outside) is a malevolent being who wishes nothing more than the destruction of mankind for unknown reasons. He waits in his home dimension in Pherkard, until he is summoned to Earth. When first summoned, Yomagn’tho appears as a small ball of fire that quickly expands to a large circle of fire with three flaming inner petals. The reptilian burrowing folk of the Rhygntu is known to worship this malignant deity.
Elder Gods 
In post-Lovecraft stories, the Elder Gods oppose the Outer Gods and the Great Old Ones. Some[who?] consider them to be non-Lovecraftian because they employ a good versus evil dichotomy which some[who?] see as contrary to the cosmic indifference of Lovecraft's fiction. Derleth attempted to retroactively group the benevolent deity Nodens in this category (who acts as deus ex machina for the protagonists in both The Dream-Quest of Unknown Kadath and "The Strange High House in the Mist").
As for Great Old Ones, Joseph S. Pulver mentions in his Nightmare Disciples (2006) a series of original Elder Gods, though lacking of any description about their true form. The story introduces entities as Adaedu, Alithlai-Tyy, Dveahtehs, Eyroix, Ovytonv, Urthuvn, Xislanyx and Xuthyos-Sihb’Bz'. Others have a cult title as Othkkartho (Sire of the Four Titans of Balance and Order), which is said to be Nodens's son, and Zehirete, who is The Pure and Holy Womb of Light. Sk’tai and Eppirfon are brothers and the former (female) has been Cthulhu's second bride who bore him a son, T'ith, now dead, murdered by Cthulhu himself.
Another Elder God with no description is Walter C. De Bill jr.'s Paighon, an extra-galactic entity which now dwells in Earth's core, said to be inimical of the Outer God Ngyr-Korath and its servitor 'Ymnar.
Bast (Goddess of Cats or Pasht) appears as a female human with a cat's head.
Drazet (The Unformed) is known only to those with access to the secrets found in the Ta’ge Fragments. It is said to be responsible for the legendary city upon which the fragments were first inscribed. Its servants are purportedly symbiotic creatures and more than likely the creatures that come down to bond with mortals in the Rite of Sacred Union.
See Brian Lumley deities.
Myrovh is inferred to be the great manipulator, pitting pawns against each other so that they will grow and change through conflict. Stories say that it maintains a Darwinistic view of life, believing that only the strong should survive, and that it takes a personal hand in those species to which it administers. Furthermore, they say that Myrovh is in some way linked with Yog-Sothoth.
Orryx (The Bright Flame) manifests as a giant pillar of blinding white and purple flames. Although its expression is bright and blinding, no one feels its heat. No one can look at Orryx more than a few seconds since the first assault, the eyes of anyone who looks sore and watery.
Oztalun (Golden and Shimmering One) is an Elder God introduced by James Ambuehl. It is symbolized by a seven-pointed star symbol, which is its own Seal.
Shavalyoth (Shadowy and Shapeless One) is an Elder God introduced by James Ambuehl, supposed to be dark and formless.
Vorvadoss* (The Flaming One, Lord of the Universal Spaces, The Troubler of the Sands, Who Waiteth in the Outer Dark) appears as a cloaked, hooded being, enveloped in green flames, with fiery eyes. He is described as son of the Elder God Nodens and the Great Old One Lythalia and has got a twin brother too, Yaggdytha.
See Brian Lumley deities.
Yaggdytha (The Incandescent One) is twin brother of Vorvadoss, manifesting as a great amorphous, incandescent ball of cyan living energy, spread itself into a web of giant talons of light.
Great Ones 
The Great Ones are the "weak gods of earth" that reign in the Dreamlands. They are protected by Nyarlathotep.
