Gozu

is a shinobi who appears in the second Naruto Shippūden filler arc. He is a subordinate of Guren.

Personality and Abilities
He's unsociable and quiet, making people unable to figure out what he's thinking, but his battle skills are without a doubt very good. He's the power type and prefers fight alone. He seems to hold a special sentiment towards Guren. His body was altered by Orochimaru, giving him great physical strength and the ability to turn his body into mud. He seems to be quite strong since while his comrades were fighting in groups in the battle royal, he held is own by himself.

Hunt for the Three-Tails Arc
After the selection battle Kabuto Yakushi and Guren held in the hideout, Gozu becomes Guren's subordinate. He seems to fight Hinata in later episodes.

Trivia

 * His name is sometimes confused with Gouzu's of the Demon Brothers (in the English dub, Gouzu's English name is romanized as Gozu, making the confusion with the names understood).
