Poseidon was the god of the sea.
Brother: Zeus Mother: Rhea Father: Cronus
Poseidon was worshipped.
Poseidon was not at all jealous of his brothers powers. He did not want to be in charge of the underworld. And certainly did not want the responsibilities his brother Zeus had shouldered. Poseidon was happy to be the king of the sea.
