King Neptune is a Triton and he is the King of the Seas of Andros.

Biography
He is the father of the twin brothers Nereus and Tritannus as well as the uncle of Aisha, and as such he could be the brother or brother-in-law of either King Teredor or Queen Niobe. Queen Ligea is his wife with whom he has three children, Nereus, Tritannus, and Tressa. It is revealed in the last episode of Season Five that Teredor is his brother, therefore making him Aisha's paternal uncle.

In Season 5, he decided to name Nereus as his heir but a jealous Tritannus disrupted the ceremony and was sent to prison. After Tritannus's escape, he disowned Tritannus and set out to hunt him down. He was later turned into a mutant along with Tressa when Tritannus invaded the palace. He made some minor appearances after the ceremony.

In the final episode, he and Ligea were relinquished from Tritannus' spell thanks to Bloom and Nereus. He then goes to the surface with his wife, Tritannus, Daphne, Bloom, Aisha and Nereus, and he was greeted by everyone as they rejoiced for their safe return. After Nereus gives Tritannus one more chance to redeem himself, Tritannus voiced out in bitterness that he did not succeed in annihilating them, leading Neptune to punish his son by sending him to Oblivion.

He then attends Andros' celebration party with his whole family.
