Character Biographies

Zabuza Momochi was born in Kirigakure. During one of Kirigakure's annual events of pitting graduating ninja against each other, Zabuza singlehandedly killed all of his peers, bringing an end to the ritual and causing him to be called the "Demon of the Hidden Mist". Zabuza would go on to become one of the Seven Shinobi Swordsmen of the Mist where he acquired his zanbatô, and also became a member of the Kirigakure ANBU. At some point in time, Zabuza found a young boy named Haku wandering the countryside, and offered to take Haku in as his tool. Haku accepted and became loyal to Zabuza, learning from Zabuza and protecting him whenever necessary. Zabuza eventually attempted a coup d'état on the Land of Water by trying to assassinate the Mizukage. The coup failed, forcing Zabuza and his subordinates to leave the country. In the hopes of gaining funds for a second coup, Zabuza became a mercenary assassin, killing anyone if the price was right. Zabuza is hired by Gato to kill the bridge builder Tazuna. After his initial attempt fails to kill Tazuna and his escorts (Kakashi Hatake and his students) and leads to his defeat, Zabuza and Haku seek a rematch after he recovers. Once tracking down Team 7 again, Zabuza is drawn into battle with Kakashi while Haku deals with his students. Although he tries to avoid Kakashi, he is eventually restrained and Kakashi prepares to kill him with his Lightning Blade. Before he can land a blow, however, Haku appears to use himself as a human shield for Zabuza, fulfilling his promise of being a tool for his master. Zabuza is freed as a result of Haku's intervention and tries to attack Kakashi, though Kakashi is able to avoid the attack and disable both of Zabuza's arms. With Zabuza no longer able to fight, Gato arrives with his henchmen to finish the job instead, ending the battle between Zabuza and Kakashi. Naruto Uzumaki, however, is angered that Zabuza has yet to show remorse for Haku's death and explains Haku's devotion to him. Brought to tears by his words, Zabuza reveals that he did care for Haku and decides to repent for what he has done. After taking a kunai in his mouth, Zabuza charges through Gato's men, being stabbed multiple times along the way though eventually reaching and killing Gato. After collapsing due to his injuries Zabuza asks to be brought to Haku's side, wanting to be by his side in death as Haku was by him in life. Kakashi complies, and in his dying moments Zabuza wishes to go to the same afterlife as Haku

Zaku Abumi is one of the three Genin from Otogakure who entered the Chunin exam. Zaku is fitted with hollow air tubes that extend through his arms and open through his palms. With these tubes, Zaku can use his chakra to perform Decapitating Air Wave and the larger scale Extreme Decapitating Air Waves of air pressure and sound in various ratios that is strong enough to crack stone and wipe out anything in its path.

Zetsu A mysterious missing-nin. Not much is known about him, other than his allegiance to Akatsuki and his function as a spy. His head appears to be enveloped in a large venus flytrap, which can also envelop the rest of his body. The right side of his face and body is black in color while his left side is white in color. To go with this, Zetsu seems to have a split personality, as the black half of his face speaks only in Katakana while the white side uses Kanji and Kana. The two halves also seem to converse with each other, and occasionally differ in opinion, such as whether to allow Tobi to fill Sasori's place in Akatsuki. His eyes are yellow and pupil-less. Zetsu frequently uses Leech All Creation: Attack Prevention Technique, allowing him to merge with the ground, trees, and other plants to travel long distances fairly quickly. He has also shown the ability to move his body during the sealing ritual, which no other Akatsuki member is capable of. As such, he serves as a lookout during the ritual. To help with this task, Zetsu has increased vision that allows him to see further than most other characters. In addition to his role as a spy, Zetsu appears to function as Akatsuki's hunter-nin. He is sent to dispose of the corpses of those used for Pein's Shapeshifting Technique, as well as recover the rings of Sasori and Deidara. He performs the former function by devouring the corpses, which fits with his "venus flytrap" theme.

Zouri is one of many people Gato hired. He worked alongside Warahi and took Tazuna's daughter, Tsunami as a hostage, only to be defeated by Naruto.
