King Poseidon was the first king of the drowned Atlantis.
History
King Poseidon ruled Atlantis around the point when the Old Ones came. Knowing he could not defeat them alone, he drew all of the mystical energy in the world and forged it into a trident. He managed to defeat the Old Ones and the most powerful among them, Icthultu, but because he had taken all the mystic energy, he also drained the power that kept Atlantis afloat, and his city drowned.
Many years later, Poseidon's trident helped his descendant Aquaman and the Justice League defeat Icthultu once again.
