Kinkaku

was one of Kumogakure's infamous Gold and Silver Brothers alongside his brother Ginkaku.

Background
The Gold and Silver Brothers are the most notorious criminals in the history of Kumogakure. Once, they were assigned to capture the Nine-Tailed Demon Fox, but were swallowed whole. However, they survived, and thrashed inside the tailed beast's stomach for two weeks, eventually forcing the Nine-Tails to regurgitate them. While in its stomach, they survived by eating the flesh of the beast. An elderly Kumo-nin noted that when the fox finally regurgitated the brothers, 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 Kumogakure's Second Raikage, the brothers staged a coup d'état that left the Second Hokage on the brink of death. At some point in his lifetime, he met Kakuzu.

Personality
Kinkaku and his brother are considered disgraces to Kumogakure due to their underhanded natures. They use deceit and betrayal indiscriminately in battle and will even attack their own comrades. He is also very prideful, and became angry when Darui chastised them, proposing to his brother that they decimate their opponent; though he seemed to be more composed than Ginkaku. One of the few things that Kinkaku did seem to care about was his brother's well-being. During their fight with Darui, Ginkaku was sucked into the Benihisago, and in response Kinkaku went into his Version 2 state out of rage.

Appearance
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. Like Naruto Uzumaki, he 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 was tattooed upon the shoulder of his exposed left arm.

Abilities
During their lifetime, Kinkaku and his brother were well-known for their prowess, members of the Allied Shinobi Forces trembled in fear when he saw them. Their presence provoked the Fourth Raikage enough that he nearly disregarded his duties as leader of the Allied Shinobi Forces in order to personally confront the pair. Kinkaku's power alone nearly demolished the entire First Division and inflicted massive casualties.

Treasured Tools
The brothers wielded the five Treasured Tools of the Sage of the Six Paths, all of which cost a large amount of chakra: enough to kill normal humans before they can utilise the tools properly. Therefore, Kinkaku is considered a weapon specialist. The brothers can use them due to the combination of their high chakra level and the Nine-Tails' chakra. By combining the Benihisago, Kōkinjō and Shichiseiken, they can capture their opponent's and body, sealing them away for good. The Bashōsen allows them to create any of the five basic elements.

Jinchūriki Transformations
According to Ao, Kinkaku possesses enormous chakra reserves with traces of the Nine-Tails' chakra mixed in due to them being swallowed and regurgitated by the Nine-Tails after surviving two weeks inside its stomach by eating some of its chakra-imbued flesh. Despite not being an actual jinchūriki, his chakra has similar potency to the Nine-Tails', making him a pseudo-jinchūriki. Having eaten so much of Nine-Tails' flesh, Kinkaku is able to shroud himself in a demon cloak at any time and even enter a Version 2 form. In this form, can produce six tails with one tail vastly longer and thicker than the others. He also retains his consciousness, unlike most jinchūriki, who lost to their bestial instincts in this form.

Kinkaku can use his chakra tails to strike with great force and range, block a torrent of kunai with his tails, throw a giant rolling tank aside and easily break out of the Shadow Imitation Technique in seconds. In the anime, he emerged unharmed from a combined barrage of various elemental ninjutsu and also displayed great speed and strength, being able to cut down several allied shinobi in an instant along with destroying the platform they were standing on. However, despite its similarity to Naruto's higher forms, it seems to lack the corrosive chakra cloak that Naruto gains in Version 2 and beyond.

Fourth Shinobi World War: Confrontation
In preparation for the Fourth Shinobi World War, Kinkaku is reincarnated by Kabuto Yakushi to fight against the Allied Shinobi Forces. Emerging from the sea near the Land of Lightning's coast, alongside his brother and among the White Zetsu Army, the two engage the opposing First Division. Confronted by Darui, he recognises that he had inherited the Third Raikage's techniques, indicating to Kinkaku that he must be rather strong.

In response to Darui's remark, he says that, since time had passed, even those from Kumogakure had lost respect for them. After Atsui and Samui arrive, Kinkaku retrieves the Bashōsen and Shichiseiken from his mouth, giving the latter to his brother, whilst the Kōkinjō wraps around his arm. Hitting both siblings with the rope, he draws out their word souls, so that Ginkaku can curse them. Reading the special word from the thrown sword, Kinkaku burns Atsui's arm, which forces him to say his forbidden word, causing him to be sealed. While his brother takes Samui hostage, Kinkaku attempts to attack Darui, only to have his arm cut off. Darui then attacks both brothers, freeing Samui, but coming into contact with the rope around Kinkaku's severed arm, which Kinkaku had kicked. He then cuts Darui's word soul and Ginkaku records it.

When Darui mistakenly utters his taboo word, he was inadvertently able to change his most said word whilst being sucked into the Benihisago, cancelling the sealing, unbeknown to the brothers. Disarming Ginkaku and knocking him into Kinkaku, Darui then commandeers the other tools. Launching his blade at the latter, he deflects the sword, only to be struck by another bombardment. Darui uses this opportunity to curse and seal Ginkaku, causing Kinkaku to go berserk and enter into his six-tailed form.

Although Darui apologises for Ginkaku, Kinkaku wreaks havoc on the battlefield, killing many despite Chōza Akimichi's efforts. Observing the Kohaku no Jōhei in Darui's possession, he concludes that they were planning to seal him within it, before ambushing and almost killing Darui if not for Kitsuchi's strike. Deflecting a barrage of kunai, Kinkaku fails to see Chōji Akimichi's approach, but he repels his attack using strength alone. However, this was merely a distraction, so Shikamaru Nara could bind his shadow.

Breaking free with ease, Kinkaku is instead taken control of by Ino Yamanaka, when he tried to kill Shikamaru. Forcing him to respond to Darui's call, he begins to be drawn into the pot, just as Ino returns to her own body. As Kinkaku is being sealed, he laments how such fools could defeat him and his brother, but Darui retorts that even though gold and silver may shine brighter, a mass of copper coins can be worth more than one gold coin.

By nightfall, Tobi arrived at the battlefield and took both the Benihisago and Kohaku no Jōhei, each containing one of the brothers inside, intending to use their Nine-Tails chakra to help enact his Eye of the Moon Plan. During the fight between Tobi and Naruto, Tobi decided to move ahead with his plans and tossed the Kohaku no Jōhei with Kinkaku still inside the pot into the Demonic Statue of the Outer Path.
