Mad scientist Dr. Lamprey has created an underwater Trojan Horse--actually a huge replica of a Portuguese Man-O-War, surrounded by a force field which "entrances" its victims. Lured to the gigantic structure, Mera is compelled to open it up Pandora-style, thereby unleashing thousands of deadly radio-operated robot fish. As the tiny mechanical army threatens to destroy the dome surrounding Atlantis--thus destroying the city and everyone in it--Aquaman and Aqualad conduct a frantic search for Dr. Lamprey's hidden radio transmitter. ~ Hal Erickson, Rovi
