Dosu Kinuta

was the unofficial leader of Team Dosu, though their team was officially led by Orochimaru disguised as a regular Sound ninja.

Personality
Dosu has demonstrated to be a very alert and logical ninja. He rarely rushes into anything before first observing and analyzing the situation. Dosu seemed very loyal to Orochimaru's cause, and to a lesser degree, his teammates. Though he claims that Sound ninja are willing to sacrifice their own teammates for their cause, he promises to avenge Zaku after his debilitating defeat by Shino Aburame. He showed dedication to Orochimaru's task of killing Sasuke Uchiha, but became disillusioned after learning that Orochimaru had given Sasuke a Orochimaru's Juinjutsu. Realizing that he and his team were pawns used to determine Sasuke's worth, Dosu becomes determined to undermine Orochimaru by completing the task of killing Sasuke.

Chunin Exam
Dosu passes the written portion of the Chunin Exams by interpreting the sound of other's pencil markings. During the second phase Dosu initiates his team's real mission: killing Sasuke Uchiha. While fighting Sakura, Rock Lee, and Team 10 in an effort to fulfill this goal, Dosu notices that Sasuke has received one of Orochimaru's cursed seals. Uncertain why Orochimaru has done this and otherwise outnumbered, his team flees. During the preliminaries Dosu defeats Choji Akimichi and is assigned to fight Shikamaru Nara during the first round of the finals. In an effort to make sure that Sasuke survives until they can fight so that Dosu can kill him personally, he challenges Gaara, Sasuke's first opponent. Gaara promptly kills him. But it was a genjutsu, and Dosu is currently Mist Hokage

Abilities
Dosu's battle style revolves around his ability to manipulate sound. Not unlike Zabuza Momochi he has a very keen awareness and understanding of soundwaves. During the first round of the Chunin Exams, he simply listened to the strokes of other ninja's pencils to determine the answers for the written test. His main attack is done with help of the "Melody Arm" on his right forearm, which he used to generate sound for his attacks. His abilities attack the inner ear, directing his sound deep into it, which would cause great pain, disorientation, and nausea. During their match, Choji attempted to block his attacks by pulling his head inside his Human Bullet Tank, only to be thwarted by the fact that by directing sound through the water in his body Dosu could still generate the effect. Choji was instantly defeated by the attack.
