Father Dagon, or simply Dagon, is (possibly) a Great Old One and one of the leaders of the Deep Ones. He is worshiped by the Deep Ones and several cults, amongst them the Esoteric Order of Dagon in Innsmouth.
He rules as a monarch of the Deep Ones alongside his consort Hydra (or Mother Hydra). He may have come from outer space along with Great Cthulhu. However, the Mythos doesn't clearly specify if Dagon or Hydra are actual Great Old Ones, or merely millennia old overgrown Deep Ones, as they are functionally immortal, never dying of old age.
Lovecraft probably took inspiration for Dagon through the ancient Mesopotamian deity of the same name, which was a god of fish, shipping and fertility.
Role in the game Edit
Dagon is one of the main antagonists of the game, being the leader of the Deep Ones who formed the Order. He is summoned by Robert Marsh on Devil's Reef during the US Marines raid on Insmouth and attacks the Cutter Urania while Jack Walters is onboard with a horde of Deep Ones. The two battle and Jack defeats him by shooting with the ships' main cannon at Dagon's head. It is heavily wounded and sinks down into the deep ocean, but not before taking the ship with him to the bottom of the seas. It is unclear whether Dagon was killed or wounded.
