From within his Sea Saucer, Black Manta sends electronic signals to a killer whale to attack Aquaman, Mera and Aqualad. Using his telepathic powers, Aquaman is unable to stop the rampaging behemoth of the depths!
When Aquaman notices an antenna on Black Manta's ship as well as on the whale, he commands a hammerhead shark to disable the antenna.
Black Manta counters by sending his Manta Men after Aquaman and Aqualad. When they fail, Black Manta turns his ray on sea anemone to ensnare the pair. Aquaman uses his powers to a man-o-war render the anemone still.
A chase through an undersea canyon follows, suddenly Black Manta crashes his saucer into the canyon and attempts to escape. He and Aquaman begin a hand-to-hand fight when, out of nowhere, Black Manta is engulfed in a whirlpool and dragged down into the abyss. Aquaman and Aqualad return to Mera knowing they haven't seen the last of Black Manta.
