Plot
After the shocking murder Atlantis' King Arthur—known to the world as the Justice League's Aquaman—life in the undersea kingdom has been radically transformed. Former terrorists have replaced the Atlantean police, crime lords control huge swaths of territory, and a deadly arsenal trained on the surface world is all at the command of King Roth, who has sworn to make Atlantis the greatest it has EVER been.
But rumors spread of a rebel in the sun-starved slums of Atlantis: an oddly familiar hero who, joined by a mysterious and powerful woman named Dolphin, becomes central to intrigues that forebode civil war! And when hints of King Arthur's return reach the surface, the exiled Lady Mera vows to find him—but with the Justice League unable to join her cause, will the Titans' Tempest help her return to Atlantis and learn if "the Aquaman" is who he seems?
