Aquaman and the Lost Kingdom

Black Manta, who failed to defeat Aquaman the first time, will stop at nothing to defeat Aquaman once and for all with his desire to avenge his father. This time, Black Manta is a tougher enemy than ever; In his hand is the legendary Black Trident, which unleashes an ancient and malevolent power. To defeat this powerful foe, Aquaman chooses to form an unlikely alliance with his imprisoned brother Orm, the former King of Atlantis. To protect their kingdom and save Aquaman's family and the world from irreversible destruction, the two half-brothers will have to put their differences aside.
