Having failed to defeat Aquaman the first time, Black Manta, still driven by the need to avenge his father’s death, will stop at nothing to take Aquaman down. This time, Black Manta is more formidable than ever, wielding the power of the mythic Black Trident, unleashing an ancient and evil force. To defeat him, Aquaman will turn to his imprisoned brother Orm, the former King of Atlantis, to forge an unlikely alliance. Together, they must set aside their differences to protect their kingdom and save Aquaman’s family, and the world, from irreversible destruction.
