"The figure, nearly ten feet in height, was taller by a full yard than the average Aihai, but presented the familar conformation of massively bulging chest and bony, many-angled limbs. The bead was featured with high-flaring ears and pit-like nostrils that narrows and expanded visibly in the twilight. The eyes were sunken in profound orbits and were wholly invisible."--Clark Ashton Smith, "Vulthoom"

An alien race, presumably from Mars, with advanced technology and an association with Vulthoom..

"There flapped rhythmically a horde of tame, trained, hybrid winded things... not altogether crows, nor moles, nor buzzards, nor ants, nor decomposed human beings, but something I cannot and must not recall."--H.P. Lovecraft, "The Festival"

An interstellar race often serving Hastur the Unnamable.

"Men of broader intellect know that there is no sharp distinction betwixt the real and the unreal..." --H.P. Lovecraft, "The Tomb"

Composed of dozens of human faces set into a thickly cylindrical, worm-like mass of sickly, purple-veined muscle, the Chakota's faces weep, shout and cry out with great woeful feeling. Whenever it devours a new victim, it grows in size and sprouts a new face to match that of the victim it just consumed.

"Cursed the ground where dead thought live new and oddly bodied, and evil the mind that is held by no head. Happy the town at night whose wizards are all ashes. For it is of old rumor that the soul of the devil-bought hastes not from his charnel clay, but fats and instructs the very worm that gnaws; till out of corruption horrid life springs, and the dull scavengers of earth wax crafty to vex it and swell monstrous to plague it. Great holes secretly are digged where earth's pores out to suffice, and things have learnt to walk that ought to crawl."-- H.P. Lovecraft, "The Festival"

Composed of thousands of worms and maggots, each individually alive and constantly moving, though they generally hold the shape of a human body. They are formed when a powerful wizard is buried and not burned, as the worms and maggots absorb the dead wizard's consciousness as they consume its body.

"Something black in the road, something that wasn't a tree. Something big and black and ropy, just squatting there, waiting, with ropy arms squirming and reaching... It came crawling up the hillside... and it was the black thing of my dreams -- that black, ropy, slimy jelly tree-thing out of the woods. It crawled up and it flowed up on its hoofs and mouths and snaky arms." --Robert Block, "Notebook Found in a Deserted House"

The servants of Shub-Niggurath. They are the "young" referred to in Shub-Niggurath's epithet, "Black Goat of the Woods with a Thousand Young".

"I think their predominant color was a greyish-green, though they had white bellies. They were mostly shiny and slippery, but the ridges of their backs were scaly. Their forms vaguely suggested the anthropoid, while their heads were the heads of fish, with prodigious bulging eyes that never closed. At the sides of their necks were palpitating gills, and their long paws were webbed. They hopped irregularly, sometimes on two legs and sometimes on four. I was somehow glad that they had no more than four limbs. Their croaking, baying voices, clearly used for articulate speech, held all the dark shades of expression which their staring faces lacked ... They were the blasphemous fish-frogs of the nameless design - living and horrible." --H.P. Lovecraft, "The Shadow Over Innsmouth"

An amphibious race who have mated with humans to create Deep One Hybrids, which eventually transform into Deep Ones themselves. At one time, they supposedly had an undersea city near Innsmouth, Massachusetts, but after a Federal raid on Innsmouth in 1928, the town was all but abandoned.

"As for the Innsmouth people - the youth hardly knew what to make of them. They were as furtive and seldom seen as animals that live in burrows, and one could hardly imagine how they passed the time apart from their desultory fishing. Perhaps - judging from the quantities of bootleg liquor they consumed - they lay for most of the daylight hours in an alcoholic stupor. They seemed sullenly banded together in some sort of fellowship and understanding - despising the world as if they had access to other and preferable spheres of entity. Their appearance - especially those staring, unwinking eyes which one never saw shut - was certainly shocking enough; and their voices were disgusting. It was awful to hear them chanting in their churches at night, and especially during their main festivals or revivals, which fell twice a year on April 30th and October 31st. They were very fond of the water, and swam a great deal in both river and harbour. Swimming races out to Devil Reef were very common, and everyone in sight seemed well able to share in this arduous sport. When one came to think of it, it was generally only rather young people who were seen about in public, and of these the oldest were apt to be the most tainted-looking. When exceptions did occur, they were mostly persons with no trace of aberrancy, like the old clerk at the hotel. One wondered what became of the bulk of the older folk, and whether the "Innsmouth look" were not a strange and insidious disease-phenomenon which increased its hold as years advanced." --H.P. Lovecraft, "The Shadow Over Innsmouth"

Bred of human and Deep One, the hybrids slowly begin to show signs of the change that will transform them into Deep Ones usually around middle age. This was so predominant in Innsmouth, that the appearance became known as the "Innsmouth Look". Innsmouth was once supposedly overrun with Hybrids until the Federal raids in 1928 ended with over 200 arrests and the small fishing town nearly collapsed.

"Vast, Polyphemous-like, and loathsome, it darted like a stupendous monster of nightmares to the monolith, about which it flung its gigantic scaly arms."--H.P. Lovecraft, "Dagon"

Father Dagon is a unique servitor of Great Cthulhu. He is a Deep One which is perhaps millions of years old, although some stories claim that he is a Star-spawn of Cthulhu. With Mother Hydra, he actively seeks to aid and protect the Deep One race.

"It was a colossal and nameless blasphemy with glaring red eyes, and it held in bony claws a thing that had been a man, gnawing at the head as a child nibbles at a stick of candy. Its position was a kind of crouch, and as one looked one felt that at any moment it might drop its present prey and seek a juicier morsel. But damn it all, it wasn't even the fiendish subject that made it such an immortal fountain-head of all panic—not that, nor the dog face with its pointed ears, bloodshot eyes, flat nose, and drooling lips. It wasn't the scaly claws nor the mould-caked body nor the half-hooved feet—none of these, though any one of them might well have driven an excitable man to madness."--H.P. Lovecraft, "Pickman's Model"

Hairless creatures with long canine muzzles, pointed ears and clawed feet that have almost become hooves, they inhabit networks of underground tunnels and crypts and eat the corpses of dead humans.

"The nightmare, plastic column of fetid, black iridescence oozed tightly onward... A shapeless congerie of protoplasmic bubbles, faintly self-luminous, and with myriads of temporary eyes forming and unfomring as pustules of greenish light all over the tunnel-filling front that bore down upon us, crushing the frantic penguins and slithering over the glistening floor that it and its kind had swept so evilly free of all litter. Still came that eldritch mocking cry -- "Tekeli-li! Tekeli-li!"--H.P. Lovecraft, "At the Mountains of Madness"

Shoggoths are often found as servants of Deep Ones and other races and are amphibious. The mad Arab, Abdul Alhazred himself attempted to desperately claim that there were none on Earth itself save for in crazed dreams. They communicate in whatever form their master race wishes, forming special organs for the purpose, but are known for their madening cry, "Tekeli-li! Tekeli-li!"

"They all lay in stone houses in their great city of R'lyeh, preserved by the spells of mighty Cthulhu for a glorious resurrection when the stars and the earth might once be ready..."--H.P. Lovecraft, "The Call of Cthulhu"

These gigantic octopoid beings resemble Cthulhu himself, but are smaller. Not all of the inhabitants of R'lyeh were trapped when it sank and some live on in the deep trenches beneath the ocean, where they are tended by Deep Ones.
