The Sharingan Revived!!

Synopsis
Zabuza is forced to release Kakashi in order to avoid Naruto's attack. Enraged by Naruto's actions, Zabuza tries to attack him, but is topped by Kakashi. Kakashi congratulates Team 7 on their success and promises to start pulling his own weight. Zabuza attacks Kakashi with his Water Release: Water Dragon Bullet Technique, and Kakashi instantly copies it with his Sharingan. As the two identical jutsu collide, Zabuza prepares another attack, only to realize that Kakashi is mimicking everything he does. Kakashi attacks with Zabuza's own Water Release: Great Waterfall Technique, something Zabuza had only been thinking of doing. After landing the attack Kakashi prepares to finish off Zabuza, but a masked boy beats him to it by seeming to kill Zabuza.
