Steropes is a sixteen-year-old cyclops under the matriarchy of Fotini. He is the one who captures the Klabautermann that Fotini sells to Water Zero and as a result of such he is considered to be a very important figure by Musashibō Uchibenkei. It should be noted that he is the main antagonist of One Piece of Music's Récit Arc du Justicier. Thus he is more of an enemy of Aharon than Thoosa.
