How To Kill A Sea King! * Single Appearance's "ALIENA" and "Ka'arl" both Die
Ka'arl, a Venusian space pirate, uses his beautiful confederate Aliena to induce Aquaman into burying a lode of uritrium, an element whose rays are deadly to Venusians. When the task is done, Ka’arl gives Aliena orders to lure the sea king into a deathtrap. But Aliena is endangered by the trap herself, and Aquaman frees both her and himself. Finally, in a last battle between Ka’arl and Aquaman, Aliena uncovers the uritrium and uses it to kill both herself and Ka’arl, to save the life of Aquaman, with whom she had fallen in love.
