Father Dagon

Dagon, also known as Father Dagon is a Great Old One and the consort of Mother Hydra, together they rule over the Lovecraftian race of the Deep Ones. Dagon is depicted as a gigantic Deep One (around 30 stories tall) and first appeared in the short story "Dagon" - since then he and his consort have more or less been established as the official rulers of the Deep Ones, though Mother Hydra seems to gain a slightly larger following.
