When the villainous group N.E.M.O. orchestrated a war between the United States and Atlantis, the Aquamarines were deployed under the leadership of Major Rhonda Ricoh, codenamed "Great White", to assassinate Atlantis' leader Aquaman. Invading Atlantis and killing two heads of state in their attempt, the Aquamarines were defeated by Aquaman and detained as prisoners-of-war.[2]
