Chuukaku (中覚, Chūkaku) was a ninja monk from the Fire Temple and the mentor of Chiriku. A ninja monk and scholar, Chuukaku taught Chiriku sometime before his death and was eventually interred at the cemetery in the Fire Temple. Kabuto would later reincarnate him by accident while looking for Chiriku. During the Fourth Shinobi World War, Kabuto deployed Chūkaku, who he saw as one of his weaker assets, in an attempt to unseal his other, stronger pawns. While attempting to undo the seal holding the Third Raikage, Chuukaku was attacked by Temari and sealed by the Fourth Division. Later, when the Impure World Reincarnation Technique was canceled, Chuukaku's soul returned to the afterlife. Anime Debut: Naruto Shippuuden Episode #316 (Source: Narutopedia)
