Born for the second time a million years ago, after being devoured by his father Kronos, Poseidon became the ruler of one third of the territory under the control of the Greek pantheon. He rules the Aegian Galaxy, which is frequently attacked by the Egyptian pantheon.
Poseidon attended an assembly of the Nine Gods at the Throne Of The Universe to judge Noriko Null's actions. A firm believer in the superiority of gods above mortals, he supported Hera's position in maintaining the status quo.
As one of the Nine Gods, Poseidon is one of the most powerful gods in the entire Universe, reaching or perhaps surpassing the power of a Primordial God.
