Kabuto's Sensei

This unnamed Jōnin led Kabuto's Genin Team during the Chūnin Exams. His Genin were all spies for Otogakure, so it is unknown if he was also spy. He is not seen again in the manga, but he appears in the anime attending Hiruzen Sarutobi's funeral and later as a member of the Nijū Shōtai.
