Oceanus

Oceanus is the Titan of the Ocean. The Atlantic Ocean to be specific. Once ruling the Mediterranean Sea as well, he gave up his position as the ruler of the Mediterranean to his nephew Poseidon. Oceanus, along with his wife Tethys, remained neutral during the Titanomachy, and as such were not imprisoned in Tartarus like most of their siblings. With Tethys, he fathered many daughters known as the Oceanids.

Notable Oceanids include Doris (who with Nereus mothered the Nereids); Calypso (famous for the role she played in the Odyssey); Clymene (the wife of Iapetus); Electra (wife of Thaumas and mother of the Harpies, Iris and Arke); Metis (Goddess of Wisdom and mother of Athena); Peitho (Goddess of Persuassion); and many others.

He also fathered many sons known as Potamoi, or river gods, who in turn fathered the Naiads.

He remains distant from the other gods but has helped in small ways over the years, especially during the Titanomachy, and is undoubtedly one of the most important of the male Titans.
