Zabuza Momochi

Zabuza Momochi is a former special-ops commando with the Hidden Mist Village on loan to Kakashi Hatake in his efforts to capture Naruto Uzumaki better known as the Nine-Tailed Fox. Zabuza was injected with a small dose of the bastardization of the Shepard Serum and later was injected with Naruto Uzumaki's blood causing him to transform into a powerful daemon. He then proceeded to go on a rampage until he was defeated by Naruto and captured by the Anbu Black Ops.

Abilities
Physical Prowess: Zabuza was very physically strong, able to effortlessly wield the large Kubikiribōchō for long periods of time, even with one hand, as well as being fast enough to match Kakashi's speed. Zabuza has shown to be proficient in taijutsu, able to fight off and kill dozens of men, using well-coordinated kicks and a kunai in his mouth. At the same time, he showed remarkable levels of stamina and endurance, able to continue fighting effectively despite the injuries he received from Naruto. Zabuza could also take a direct hit from a powerful water technique seemingly without major damage and still move relatively normal shortly afterwards.

Zabuza was also a master of stealth and assassination. He was most renowned throughout all countries for his high skill in killing opponents through zero visibility. Kakashi noted that his Silent Killing prowess was second to none. This technique puts the victim under tremendous pressure before Zabuza even attacks, as it is noted that even the slightest movement of the eye was enough to alert Zabuza of his victim's location.

Guillotine Sword: During his time as a mist-ninja, Zabuza was one of the Seven Swordsmen of the Mist, a group composed of the village's top swordsmen. The generation of swordsmen he belonged to was noted as the strongest ever produced within Kirigakure, a further testament to Zabuza's impressive skills. Zabuza's signature weapon was the Kubikiribōchō, an over-sized broad sword, whose shape was thought to decapitate enemies. This large weapon has the unique ability to absorb and utilise the iron from all the blood it sheds, from whoever it cuts, in order to reform itself if damaged or broken. Zabuza was a master in its use, being capable of dispatching numerous enemies with a few slashes, and claiming that his sword "never cut a second time", implying to have killed a large number of people with a single attack.

The weapon's weight didn't seem to slow Zabuza down at all, as he could employ it in combat for extended periods of time with no visible strain on himself. Apart from handling it very skilfully, Zabuza could also throw it spinning at several enemies with enough power to lodge itself into a hard tree trunk.

Nature Affinity: Zabuza had great skill in Water Release techniques. He could perform several of them while keeping a separate one active. He could maintain several of these clones at the same time, often using them as diversions. He also showed proficiency in large-scale, highly destructive water-attacks from launching powerful torrents of water in the forms of dragon bullets and giant waterfalls at his opponents.

Zabuza was especially adept at the Hiding in Mist Technique, as it made his Silent Killing even easier to perform. By blanketing the area in a thick mist, Zabuza could blind his targets, making it even more difficult for them to defend against him. In this manner, Zabuza was capable of carrying out stealthy attacks even in completely open spaces, able to suddenly disappear from an enemy's sight and then strike unseen. His skill with this technique was such that he could create an impenetrable mist without the need of an immediate source of water nearby. Even Kabuto Yakushi kept Zabuza's use of the technique in high regard.

Intelligence: While he preferred using direct attacks, Zabuza was also highly capable at misdirections. From his Anbu days, Zabuza possessed extensive knowledge of the human body's pressure points and most vulnerable organs. Zabuza was also knowledgeable in foreign techniques and kekkei genkai, having knowledge of the Sharingan and instantly recognising the Shadow Clone Technique.
