Poseidon is one of Dr. Gaia's Mythos Cyborgs, introduced during the Mythos arc of Cyborg 009: The Cyborg Soldier. He's essentially an unstoppable force in his element—the ocean—and won't hesitate to take down anyone who ventures into his underwater territory. As a member of the Mythos team, he's among the series' most formidable aquatic threats.
