In "Beyond the Poseidon Adventure," Aquaman is thrown into a mystery when he realizes the Black Manta he’s been battling isn’t the real threat. With Mera’s life hanging in the balance and her only hope tied to returning to her dying home dimension of Xebel, the two heroes set out to track down Ocean Master—only to lose him in the chaos of a sudden, violent confrontation.
