The Sharingan Revived!! (蘇る写輪眼!!, Yomigaeru Sharingan!!) is chapter 15 of the original Naruto manga.
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 stopped 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 techniques collide, Zabuza prepares another attack, only to realise 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.
