Zabuza 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 zanbatō, 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. Z Being from Kirigakure, Zabuza excels in water-oriented jutsu, some of which are exclusive to him. In addition to the offensive capabilities of his water jutsu, Zabuza is very skilled in assassinations.
