The Sea Dragon Scale (シードラゴンスケイル, Shī Doragon Sukeiru) is one of the Scales of Poseidon's Marina Generals. In both the original series and the Episode G prequel, it was worn by Kanon, who used it when he impersonated a Marina General in order to control Poseidon. In the manga The Lost Canvas, it was worn by Unity, the son of the leader of the Blue Warriors.
