Sephiroth has long platinum hair and bright cyan eyes with cat-like pupils, and is depicted in a black coat decorated with metallic pauldrons. Since appearing as Safer Sephiroth in the final battle of the game, Sephiroth has had a single black wing on his back, referencing his theme music "One Winged Angel". When "" was released, the staff stated that the reason the wing was black was to suggest evil. Nomura has stated that Sephiroth was made to be a complete contrast to the game's main protagonist, Cloud, who was originally designed to have slicked-back, black hair with no spikes. His weapon, the "Masamune", which has been featured in numerous "Final Fantasy" titles, is an elongated nodachi that he learned to use during his days in SOLDIER. The Masamune is named after the famous Japanese swordsmith Goro Nyudo Masamune, whose blades are considered national treasures in Japan today. When designing Cloud and Sephiroth, Nomura was influenced by his view of their rivalry mirroring the legendary animosity between Miyamoto Musashi and Sasaki Kojirō, with Cloud and Sephiroth being Musashi and Kojirō respectively. Sephiroth's look was defined as ""kakkoii"", a Japanese term combining good looks with coolness.
