Amphitrite

Amphitrite (Αμφιτρίτη in Ancient Greek) is a sea-goddess, an Oceanid or Nereid depending on the source. Amphitrite is the daughter of Oceanus and Tethys or Nereus and Doris and wife of Poseidon.

History
After her father was replaced as the ruler of the seas by Poseidon, Amphitrite became his wife and the Queen of the Ocean. They had a son, Triton, his father's heir.

Appearance
Amphitrite is beautiful, with flowing black hair and little horns like crab claws. She wears green armor. Her little crab Horns maybe an inheritance from her Father, Oceanus.

Personality
Amphitrite is a formal sea goddess, calling her husband 'my lord'. She seems hurt by her husbands' liasons, and probably wasn't happy when Poseidon promised on the River Styx that he wouldn't have anymore demigod children, but it was not kept. In myths though, she is not jealous of her husband's affairs with mortal women, but doesn't approve of it either.
