Gozu

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.

Hunt for the Three-Tails Arc
After the selection battle Kabuto Yakushi and Guren held in the hideout, Gozu becomes Guren's subordinate.

Trvia

 * 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).
