After a precipitous fall down an escape chute, Megan and party land in a kind of warehouse, where they are again attacked by the pursuing Dark-01. Another pitched battle takes place. Back at Zentrix, meanwhile, OmicronPsy prepares new robots and summons Silver-General. Deep in the Pyramid foundations, Megan locates the mini-submarine, in which they make good their escape. Diving into deep ocean, Megan and Zeus are chased all over by Dark-01, but at the last minute, the sound of torpedoes exploding rouses a gigantic fish-the Monster-which saves Megan by swallowing Dark-01 whole. The action is so violent that Megan and her friends all black out. Local resident, 11-year old Nick, whilst out in his submarine, rescues Megan and party and takes them in tow.
