An offshore oil rig in the Gulf of Mexico is attacked by the scurrilous Scavo and the Sea Scavengers. Swimming to the rescue, Aquaman and Aqua-lad discover that Scavo has outfitted himself with a "mech", namely a Subma-Robot which rips things apart and spews out deadly steel bubbles. For bad measure, Scavo deploys a thermal ray gun, rendering the ocean boiling hot! But Aquaman is able to telepathically summon his finny friends to help him save the day. ~ Hal Erickson, Rovi
