Unable to defeat Aquaman the first time, Black Manta, still driven by the need to avenge his father\'s death, will stop at nothing to defeat Aquaman once and for all. This time, Black Manta is more formidable than ever, wielding the power of the mythical Black Trident, which unleashes an ancient and ominous force. To defeat him, Aquaman will turn to his imprisoned brother Orm, the former king of Atlantis, to form an unexpected alliance. Together, they must set aside their differences to protect their kingdom and save Aquaman\'s family and the world from irreversible destruction.
