An Atlantean criminal named Pomoxis lures Aquaman into a trap. He uses a device which sends the sea king backwards in time some 2,500 years. Aquaman encounters the armies of Greece, who mistake him for the sea god, Poseidon. Meanwhile in the present, Pomoxis attempts to conquer Atlantis. Aqualad fights against him until such time that Aquaman can return to the present. Commanding an army of fish, the two heroes manage to defeat Pomoxis' battalion and restore order to Atlantis.
