Chūkichi

was a former Kirigakure ninja, who has subsequently been resurrected by Kabuto in order to fight in the Fourth Great Shinobi War. He was apparently a very powerful and well noted shinobi during his lifetime, enough to warrant his inclusion as a sensor and a backup within Kabuto's ambush and distraction squadron, alongside both Deidara and Sasori.

Appearance
Chūkichi is depicted as a relatively tall man, wearing attire that is reminiscent of clothing associated with some individuals connected with Kirigakure's Hunter-nin, chiefly Ao and Haku. He is also observed wearing a pair of small glasses and a beaded necklace, with his broad face being further distinguished by the presence of three distinct stripes and his forehead protector, that he wears like a bandana.

Confining the Jinchūriki Arc
Shortly after his resurrection, Chūkichi was assigned to an ambush and distraction squadron alongside Deidara, Sasori and a deceased member of Konohagakure's Root named Shin at the behest of Kabuto. However; upon the realization that both of the two unknown individuals commanding him where affiliated with Akatsuki, Chūkichi was evidently outraged and swiftly refused to follow any of their demands, leading to the destruction of his personality.

Now suitably subdued and atop of one of Deidara's clay birds, Chūkichi manages to locate a number of infiltrating shinobi, before quickly alerting the remainder of his group to their presence.

Trivia

 * Chūkuchi bears numerous stark similarities in appearance to another unnamed character associated with the usage of Hiruko's Chimera Technique, during Naruto Shippūden 3: Inheritors of the Will of Fire.
