Once freed from the Water Prison, Kakashi uses his Sharingan to replicate many of Zabuza's water-based attacks, causing him to become agitated and is easily defeated. At the last second, Zabuza is seemingly killed by a young masked hunter ninja from the Hidden Mist Village. Naruto is angry and jealous that someone so young could easily defeat an opponent that gave Team 7 so much trouble, but Kakashi says that there are many ninja younger than Naruto yet stronger than himself. The hunter-ninja leaves with Zabuza's body, and Kakashi then collapses from fatigue as a result of using his Sharingan for too long.
