Suigetsu Houzuki

Suigetsu Hozuki is a former experimental subject of Orochimaru. Suigetsu once trained to be one of the Seven Swordsmen of the Mist and as such has a number of traits consistent with other known members. In addition to having sharklike teeth Suigetsu enjoys killing Kisame Hoshigaki one of the Seven Swordsmen claims Suigetsu is a prodigy at the art of murder as he has a habit of chopping off his victims limbs before beheading them. He is also very confident in his abilities since he has threatened Sasuke Uchiha on more than one occasion. Not afraid to speak his mind and always doing as he pleases Suigetsu clashed with Sasuke at first but eventually came to accept Sasukes position and even put himself in harms way to protect him. After joining Hebi Sasuke takes Suigetsu to retrieve Zabuza Momochis giant Kubikiri Hch from his graveside. Suigetsu can wield the weapon with relative ease despite its enormous size and weight. In his allegiance with Sasuke Suigetsu hopes to acquire the sword of Kisame as well which Karin assumes to mean that he wants to collect all of the swords of the Seven Swordsmen. Suigetsu is able to reduce himself to liquid form and return to bodily form at will. This ability also allows him to change his body shape giving him the ability to increase the size of his limbs proportionally increasing his strength if necessary. It also makes striking him somewhat difficult since he is made of liquid any sufficiently powerful strike will go right through his watery form. Suigetsu is the first ninja seen carrying water bottles on his outfit. Given his somewhat frequent desire to consume water it is suggested that Suigetsu requires regular hydration to sustain his watery form.
