Gōzu

Gouzu, romanized in the dub as Gozu, is a Chunin from Kirigakure.

Personality
It is stated in the first fan book that Gouzu is the elder of the Demon Brothers. They also describe him as a cold-hearted and merciless killer.

5 Years Before Series Start
Gouzu and his brother Meizu were with Zabuza Momochi and Haku on the failed assassination of the Mizukage, and fled with them out of Kiri. Whether or not the Mizukage was Madara Uchiha or someone else is unknown.

Land of Waves Story arc
Five years later, Gouzu and Meizu formed the Demon Brothers. They were hired by Gato to kill the Bridge Builder Tazuna, and therefore stopping the work on the bridge from the Land of Waves, making all of the Wave Country's citizens lose all their hope. They both attacked Tazuna, who was guarded by Team 7. After a little quick battle, they were tied up to a tree and left there.

Abilities
Gouzu and his sibling are a paragon of coordination attacking. His large metal gauntlets house a retractable shuriken chain running between the two of them, which they can use to bind an enemy and then slice them to pieces. In the event that the shuriken chain is neutralized, Gouzu also has a release mechanism, to free him from Meizu for individual attacks. He uses the sharp, poisoned claws on his gauntlets to shred his foes. As a Kiri Chunin, Gouzu is renowned for his fighting resolve.

Trvia

 * The Demon Brothers are very popular with a lot of fans despite appearing in only one chapter / episode.
 * Some people get confused with the Gozu of Team Guren, a character from one of the filler arcs in the Shippuden series, and Gouzu's English name which is romanized as "Gozu".
