Poseidon

Poseidon is one of the Big Three in Greek Mythology, the god of the ocean, seas, horses, and water. In this case, Zeus is trying to overthrow Poseidon and Hades and take ultimate power. Poseidon will give you his trident, which will aid you in battle with Zeus. To reach him, you must go to the Grove of Temples. In his temple, use the starfish. Go to his beach. Swim down to the ocean. Hercules must lift the rock that blocks the entrance. He also appears in Super Villain Island, where he rises out of the sea to give you his Trident, so you can defeat Zeus.
