Gozu (Earth-2213)

Gozu was a chunin, who, alongside his twin brother Meizu, defected from the Kirigakure and started working as a missing-nin 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.

Personality
Gozu had little patience to failure and the patience of his brother, Meizu, which made the siblings be in constant state of conflict.
