Kinkaku

Kinkaku was a burly shinobi with a muscular build and towering stature. He had light-coloured eyes with dark-coloured sclera, grey-toned skin (depicted as fair-coloured in the anime), as well as long, blond hair with prominent dark tips, arranged in a style reminiscent of a Native American headdress. These features are accentuated by the presence of two distinctive horns that emerge from the abundant hair on his head, as well as a rectangular marking on his nose. He also had whisker-like marks on his face. His typical attire comprises of a standard Kumogakure flak jacket that is black on the edges and worn over a purple, high-collared, sleeveless uniform. He wore a purple forehead protector and a pair of simple wrist-guards. The kanji for "gold" (金, kin) was tattooed upon the shoulder of his exposed left arm.

During the First Raikage's reign, he and Ginkaku were part of a team that was assigned to capture the Nine-Tailed Demon Fox, but the two were swallowed during the confrontation. However, they survived by eating the flesh of the beast, and thrashed inside the tailed beast's stomach for two weeks, eventually forcing the Nine-Tails to regurgitate them. Upon their escape, they both came out looking like miniature versions of the beast, due to having acquired a portion of the fox's chakra. During a peace treaty ceremony between Konohagakure's Second Hokage and Kumo's Second Raikage, the two brothers staged a coup d'état that left the Hokage on the brink of death. During the First Shinobi World War, the Kinkaku force cornered the Second Hokage and his Escort Unit — an altercation which ended in Kinkaku killing the Hokage. At some point, he met Kakuzu, and he was still alive after the appointment of the Third Raikage. For his crimes, he became one of the most notorious criminals in the history of Kumo.
