Failing 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 down 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 evil force. To defeat him, Aquaman will turn to his imprisoned brother Orm, the former King of Atlantis, to form an unlikely alliance. Together, they must put their differences aside to protect their kingdom and save Aquaman’s family, and the world, from irreversible destruction.
