We are introduced to Arthur Curry, the half-human, half-Atlantean son of the queen of Atlantis. Arthur has always struggled to find a place in both worlds, but when his brother Orm attempts to unite the seven underwater kingdoms and declare war on the surface world, Arthur is forced to confront his destiny and take up the mantle of Aquaman. Along the way, he teams up with Mera, an Atlantean princess, to find the legendary trident of Poseidon, which will give him the power to defeat his brother and save both worlds.
