The son of an ordinary man and a daughter of Atlantis, Aquaman finally dared to accept responsibility as ruler of his people. With the help of a trident, he manages to handle most of the dangers. until a powerful villain appears, the pirate Black Manta, who also brings with him an entire army. Aquaman calls for help from Bethman, who responds immediately, but this is little, since this time the enemy is actually incredibly strong.
Aquaman feels his responsibility as ruler of Atlantis and therefore makes an alliance that he does not like, but that will benefit the underwater kingdom – with his cousin Orm. Former enemies have to learn to negotiate with each other to give the enemy a worthy rebuff. They fight together because they separate them so they cannot win even with the great power of the trident. But Aquaman’s human side also helps in this more difficult battle.
