(Suiton: Suikōtoppa) – Water Release: Water Shark Breakthrough
Zabuza walks to a nearby water source. As he gets there, he begins to perform the technique. He began to convert his raw chakra in to suiton chakra and then channeling it into the water source next to him. Once he channeled enough chakra into the water source he began to use shape manipulation. The water source he was using started to rise, and form into a shark that was jumping outward, being manipulated so it targets the dummy set up for the technique.
(Suiton: Suiben) - Water Release: Water whip
Finally some hand signs come into play, my boy. Alright first off, Zabuza takes a stance where his legs are spread out and slightly bended and begins to perform three hand seals (Rat, Dog Ox) and channels his water chakra after converting his raw chakra into it, to his hands and released that chakra into the grip of his hands and begin to shape it, taking the form of a whip of water.
(Suiton: Mizuame Nababara) - Water Style: Starch Syrup Capture Field
This is one of my more "liked" jutsu in the category of water. Very versatile and can be used with many techniques in combos. Zabuza begins this technique by performing the hand seals Ram and Tiger and begins to channel a vast amount of chakra into his mouth and converts it into his water chakra. After gathering enough chakra into his mouth he released that chakra into a stream, releasing a sticky adhesive liquid aimed at the targeted dummy.
(Mizu Bunshin) - Water Release: Water Clone
Getting by a nearby water source Zabuza begins instruction by performing the Tiger handseal. Channeling his suiton chakra into the water source, after gathering an amount that equals up to his body, he begins to use shape manipulation to form a clone of himself that looks exactly like him, a replica you can say. However it is substantially weaker than the original and has to be maintained.
(Suiton: Suigandan) - Water Release: Water Fang Bullet
Zabuza gets on a water source and then afterwards channels his water chakra into the water source which he then manipulates that water to shoot up as two masses aimed for the dummy.
Suiton: Kirigakure Shiryoku Hakudatsu) - Water Release: Hidden Mist Eye Sight Deprevation
Zabuza uses the hiding in the mist jutsu beforehand. He then focuses his water chakra throughout his body and breaks it down in his body to small droplets of water which he begins to exhale out of his mouth to have them suspended in the air so a mist gets created that becomes bigger and bigger by focusing more chakra into it untill you can't see anything but the mist. Then he concentrates more chakra to channel into the formed mist and position it by the angle where the sun is in order to cause a bright light in the mist that blinds you.
