After joining Hebi, Sasuke takes Suigetsu to retrieve Zabuza Momochi's giant Kubikiri Hōchō 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.
