Gozū (Earth-2165)

Gozu was a bender chūnin, who, alongside his twin brother Meizu, defected from the Kirigakure and started working as a rōnin at the side of Zabuza Momochi.

Biography
At a young age, Gozu and his twin brother Meizu abandoned the Kirigakure after a failed coup against the Mizukage Yagura Karatachi, leading them to start a new life as mercenaries and assassins.

In 189 AG, the siblings were sent by Zabuza to kill Tazuna. Using the Hiding in Water Technique to do so, they took Team 7 by surprise in a stealth attack. The pair was seemingly able to kill Kakashi Hatake without much effort, but as they approached Naruto Uzumaki, they were stopped by Sasuke Uzumaki, who broke a chain that connected the siblings. Kakashi then appeared and revealed he had his body replaced with a Body Replacement Technique. Beaten and defeated, the twins were tied to a tree so they could later be collected by authorities.
