Father Dagon

Dagon is a minor 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 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.
