Aquaman and the Lost Kingdom

After an unsuccessful attempt to defeat Aquaman, Black Manta is still unwilling to give up avenging his father and vows to destroy Aquaman. This time, he finds the legendary Trident of Darkness and unleashes an ancient evil force that is more menacing than ever. To contend with this, Aquaman turns to his imprisoned brother Orm (also the former king of Atlantis) for help and forms an unexpected alliance. They must put aside old enmities and fight together to defend the kingdom, save their families, and save the world from the impending disaster.
