Team Dosu

Team Dosu was one of two squads sent by Orochimaru to infiltrate the Chūnin Exams in Konoha. Whereas the other team disguised itself as Konoha ninja to spy on the participants, Team Dosu entered as Otogakure genin. Accordingly, all three members used sound-based techniques. Orochimaru instructed them to kill Sasuke Uchiha in order to test his potential host's abilities, the three losing his favor once defeated despite how Dosu fared in the exams while Kin and Zaku lost in their respective matches with Shikamaru Nara and Shino Aburame. Though he made through the preliminaries, wanting to kill Sasuke upon realizing that his groups were only his pawns, Dosu gets himself killed by Gaara while challenging him before the finals. Kin and Zaku, on the other hand, were later used as sacrifices for Orochimaru to reincarnate Hashirama and Tobirama Senju during the invasion of Konoha.
