Kinuta, Dosu

ドス・キヌタ

Dosu is a genin from the Sound Village and the leader of his squad. During the Chunin Exams, they operated under Orochimaru's direct supervision. Dosu employs a sound-amplifying device on his left arm, known as a melody arm, to intensify the vibrations generated when he strikes an object. This causes damage to opponents' ears and disrupts their sense of balance. He was the sole member of his squad to advance to the second stage of the Chunin Exams after defeating Choji Akimichi.
He demonstrated dedication to Orochimaru's mission to kill Sasuke Uchiha, but later became disillusioned upon learning that Orochimaru had bestowed a cursed seal upon Sasuke. Realizing that he and his team were merely pawns used to assess Sasuke's worth, Dosu's perspective shifted; he lost all loyalty toward Orochimaru and vowed to kill Sasuke to undermine him. Consequently, he attempted to take down Gaara before their actual match to reduce obstacles in advance, a rash decision that ultimately cost Dosu his life.
