Suigetsu Hōzuki

Suigetsu is a lean-built young man of average height, straight white hair with a light-blue tint to it in the anime, almond shaped purple eyes, and like most of the members of the Seven Ninja Swordsmen of the Mist, he has pointed teeth — one of which sticks out even when his mouth is closed. He wears a purple, sleeveless shirt with blue pants, sandals and a belt around his waist with water bottles attached to it. He also wears another belt strapped to his chest which he uses to carry the Kubikiribōchō. Due to his special body, Suigetsu is able to alter his form at will, usually to aid in his techniques and when rendered unconscious, he is reduced to a jelly-like state. Whenever he is seen recovering from these unconscious states he is placed in a large tank of water and resembles a fish-like being. Years later, Suigetsu opted to wear a dark, high-collared button down attire which had light-coloured, upturned sleeves. He wore two belts around his waist, a simple one and another larger one with two pouches — one at each side.

Suigetsu was born in Kirigakure and was reputed alongside his brother, Mangetsu, to be the incarnation of the demon Zabuza Momochi. He and Mangetsu aspired to inherit the title of Seven Ninja Swordsmen of the Mist. This acted as their motivation to finish cruel missions day by day. While Mangetsu eventually became one of the seven, Suigetsu's motivation was shattered with the premature death of his brother, and he changed his ambition to "collecting all of the swords", in order to retrieve all seven original blades that have been passed down by the swordsmen, so that he could rebuild the group and become its leader. With the humiliation of being captured and experimented on by Orochimaru and Kabuto Yakushi, his ambition was put on hold. Through these experiments, Kabuto at least, was able to replicate Suigetsu's unique secret ability to liquefy himself at will. At some point in the past, he had to fight with Jūgo. In the anime, about two years after Sasuke joined Orochimaru, the young Uchiha delivered a vial for research on Suigetsu. Upon seeing the young Uchiha, Suigetsu asked Sasuke to free him, who simply said he had to prove his strength. As the medical-nin came in to begin their tests, Suigetsu noticed one of them was in a daze (unaware he was being controlled by Sasuke's Sharingan). The medical-nin then opened Suigetsu's chamber, allowing him to break free from the base. Soon afterwards, he was pursued by Sasuke and Karin. Using his various water abilities, he was able to fend off the duo. Taking Sasuke's sword and delighting in its design, he attacked Karin, only to be caught off guard and subdued by her chakra chain, allowing Karin to take him back to the base.
