Dosu Kinuta

Dosu is a genin from the Sound Village, and leader of his squad. They were under the direct supervision of Orochimaru during the chunin exams. Dosu uses a sound amplifying device on his left arm, called a melody arm, to increase the vibrations he makes when he hits something, causing damage to the opponents ears and messes up their sense of balance. He is the only member of his squad to advance to the second stage in the chunin exams after defeating Choji Akimichi. When he learns that Orochimaru favors Sasuke more than him, Dosu sets out to prove himself by killing Gaara. However, Gaara's demon quickly kills him with a sweep of its giant tail.
