|“||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.||„|
|~ Description of Deep Ones|
The Deep Ones, also known as Merrow, are arguably one of Lovecraft's most iconic monsters next to the legendary Cthulhu and have inspired innumerable parodies, rip-offs and homages in almost all forms of media imaginable.
They are semi-aquatic beasts under the command of Dagon and Mother Hydra, two ancient, oldest Deep Ones and lesser Elder-Things who are also worshipped by the dangerous religious cult known as the Esoteric Order of Dagon, and their sinister worship of the Great Old Ones often puts them at odds with humanity: however these devious creatures have a liking of interbreeding with humanity to produce monstrous offspring that will grow more and more alien as they grow older until eventually they return to the ocean to be with their own kind.
Through millennia humanity had advanced so much in terms of civilization that they can match Deep Ones in terms of firepower on even terms. So rather than confronting humanity outright, Deep Ones decided to conquer humanity with more subtle approach: infiltrating into human society and create hybrid races who would in time become Deep Ones themselves and overrun humanity's population. And Innsmouth, was merely Deep Ones' stepping stone of their expansionist plot.
Deep Ones are described as either a hybrid of man and fish or man and frog, regardless of their traits all depictions show them as followers of the Great Old Ones and they obey the whims of their king and queen without question (some sources have Dagon and Mother Hydra as lesser gods, others simply have them as powerful Deep Ones). Despite being primarily marine creatures, they can come to the surface, and can survive on land for extended periods of time.
All Deep Ones are immortal; none die except by accident or violence. They are said to serve the beings known as Father Dagon and Mother Hydra, as well as Cthulhu. They are opposed by mysterious beings known as the Old Gods, whose powerful magic can keep them in check. This detail is one of the vestigial hints that August Derleth developed as the mostly unnamed Elder Gods.
Appearance in Other Media
The Deep Ones play an important role as antagonists in the Call Of Cthulhu role-playing universe as well as videogames and literature based on this subgenre of Lovecraftian horror, such as the video game "Call of Cthulhu: Dark Corners of the Earth" where both the Deep Ones and their human cultist worshippers including the "Innsmouth Citizens" within the town of Innsmotuh are the main antagonists.
The are a gang of minor antagonists from the Lovecraftian video-game, Call of Cthulhu: Dark Corners of The World and as their name implies, are the citizens of the eerie town of Innsmouth. Like many of their fellow inhabitants of Innsmouth, they are allied with the Order of Dagon and may also be either Deep Ones in disguise or hybrid human/Deep One spawn.
