Poseidon

Poseidon Named after Greek Sea God, is the Protective Star of Neptune. He is a guard star made to Ultron's wishes and assists the man who defeated Sauron and his minions. After separating the stars of his protective career, he set out to search for Apollo. During the search, he stumbles upon Ares who is fighting Arrest in the orbit of Mars. After seeing that the Martian defender is losing, he rescued by dragging people after the fight and he was unknowingly in Mars' suspension net.

After leaving Ares in Mars, he found a way to infiltrate the Great Void Star by disguising himself as a normal robot grunt. However, during his infiltration, he was given a shard of Dark Ice after Sauron ordered all of his minions to strengthened by it. The Dark Ice corrupted Poseidon but not enough to follow Sauron. Poseidon went berserk, due to him fighing the effect of the Dark Ice. He went on a search to find Apollo, nonetheless, and refused anyone from coming near the sun guardian.

Poseidon's personality is somewhat playful. It is also shown that Poseidon is quite close to Apollo. Poseidon uses a trident like weapon in combat. Upon summoning his star energy, he performs his special attack called Sea Lord Thunder, which consists of a high jump and hurdling his weapon towards the enemy.
