Black Manta is consumed by a thirst for revenge after the death of his father, and he sets his sights on Aquaman as the one responsible. Armed with the formidable power of the Black Trident, a weapon of ancient and destructive might, Black Manta becomes an increasingly dangerous adversary. With the power to threaten not only Aquaman but the very stability of Atlantis itself, Black Manta’s vengeful quest turns into an all-out war.
To defend his kingdom and stop his old nemesis, Arthur Curry—Aquaman—must make an unexpected and difficult decision. In a desperate bid to protect Atlantis from Black Manta’s wrath, Arthur forms a reluctant alliance with his estranged and imprisoned brother, Orm, also known as Ocean Master. The two brothers, once bitter enemies, are forced to put aside their differences and unite against a common threat that could destroy everything they hold dear.
As the stakes rise, Arthur must confront not only Black Manta’s deadly plans but also the deep-rooted conflicts within his own family. Together, Aquaman and Ocean Master will have to navigate their fraught relationship while trying to safeguard Atlantis from the ultimate destruction. In a battle where power, loyalty, and bloodlines collide, the fate of Atlantis hangs in the balance.
