Kurama (new host)

Kurama more commonly known as the Nine-Tails, is one of the nine tailed beasts. Centuries of being regarded as a mindless monster and sought after as a tool for war caused Kurama to hate humans. After being sealed into Naruto Uzumaki, Kurama attempts to maintain its cynical perspective about the world, but with Naruto's insistence on treating it with respect, the fox slowly overturns its hatred.

Kurama and the tailed beasts first came into being in the waning days of Hagoromo Ōtsutsuki, who used his Creation of All Things Technique to divide the Ten-Tails' chakra into nine separate bodies and give them each a name. Sometime after being created, the Sage explained to the young tailed beasts that a link existed between them despite their separation. He also foretold of a day when they would be brought together again—though not as they were—and that at that time someone would emerge to show them what true power is. Before his death, Hagoromo sent Kurama to live in a temple built for the purpose of protecting it in a forest region with mountains that would later become part of the Land of Fire. Over time, Kurama gained a fearsome reputation as a natural disaster that can desolate areas where the darkest aspects of human nature collect and fester.

After Madara Uchiha's defection from Konohagakure, he found Kurama and used his Sharingan to control it, forcing the fox to help him fight against Hashirama Senju, the First Hokage. The epic battle left a colossal scar in the earth that would come to be called the Valley of the End. After his victory over Madara, Hashirama's wife, Mito Uzumaki, sealed the fox within herself, becoming its first jinchūriki.

Over the long period of time that included the First and Second Shinobi World Wars, Mito kept Kurama at bay except when the seal nearly broke when she was going through childbirth. Towards the final years of Mito's life, it was decided that a new jinchūriki would have to be found, and that was another member of her clan, Kushina Uzumaki. Although Kushina was terrified when she learned of it, Mito comforted her young successor by telling her that by filling herself with love, Kushina would overcome the fox's hatred. This was shown years later that despite Kurama's constant attempts to destroy her hope for happiness as its jinchūriki and coerce her to break the seal, Kushina's love for Minato Namikaze and his love for her were proven to be strong enough to contain the fox.

Soon after the end of the Third Shinobi World War, the Third Hokage made special arrangements for Minato to ensure that Kurama would remain sealed inside Kushina while she gave birth to Naruto on the night of October 10. However, despite keeping the childbirth a secret, a masked man called Tobi tracked down their location, killed their escorts, and held Naruto hostage, forcing Minato to quickly rescue him and teleport him to safety. Right after Tobi captured Kushina, he extracted and seized control of Kurama and tried to have the fox kill its barely surviving jinchūriki, but Minato made it in time to save her. Soon afterwards, the masked man summoned Kurama into Konoha and ordered it to destroy the village.

While Kurama was rampaging in the village, Minato fought against Tobi and soon managed to place a Contract Seal on him, which freed the fox from his control. Despite that, Kurama still harboured resentment against Konoha for sealing it away and continued decimating the shinobi forces that tried to repel it. As it prepared a Tailed Beast Ball, Minato summoned Gamabunta on top of the fox and quickly teleported it to Kushina and Naruto's location, letting its Tailed Beast Ball detonate away from the village. Already dying from the extraction, Kushina used her remaining strength to restrain Kurama, planning to seal the fox back inside her so it would die with her. However, knowing that Kurama would revive without a host and how great a threat Tobi was Minato instead came up with a plan to give his son the means to combat the masked man in the future.

Because it was impossible for Minato to seal Kurama entirely on his own, he first used the Dead Demon Consuming Seal to separate and seal the fox's Yin half within himself and then prepared the Eight Trigrams Seal to imprison the Yang half within Naruto. Realising what they were planning, Kurama attempted to kill Naruto, but both of the parents used themselves as shields and completed the sealing. Although greatly frustrated of being sealed again, Kurama decided to wait for the time when it could influence Naruto to use its power to break the seal. Throughout the years, Kurama weakened the seal through the cracks of its formation by constantly sending out small portions of its chakra, which had positive side-effects on Naruto, such as amplifying his naturally large chakra reserves and healing ability, being able to heal from minor wounds within seconds to major injuries within a day.

Kurama is characterised as a snarky and shrewd individual. It uses "elder fox" when referring to itself, which is generally used by older men. Kurama expresses great pride in its power, believing itself to be the strongest of the tailed beasts due to its belief that their strength is determined by their number of tails, which earned Kurama nothing but disapproval from its brethren, especially Shukaku. The fox would also react out of jealousy whenever Naruto was not using its power. Conversely, Kurama openly acknowledged the fact that it alone doesn't stand a chance against the Ten-Tails,band from its past experience with Madara, the fox knew full well he was not an opponent to be underestimated, even when he was seemingly pushed into a corner. Kurama holds great respect to Hagoromo Ōtsutsuki; during the tailed beasts' youth, the fox shed tears after the Sage had imparted his final words to them. Kurama's manner of speech is often harsh, but deep down it has a supportive disposition, an ability to express concern for its allies and give some words of encouragement. In addition, thanks to its exploits during the Fourth Shinobi World War and working alongside Naruto, Kurama's peaceful existence expanded to the Five Great Shinobi Countries, as it would talk directly to the other Kage and assist over important matters.

Kurama also has a comical side; the fox brazenly teases his hosts.

Kurama is a red-orange coloured kitsune with black fur around its red eyes that stretch up to its ears, and nine long swiping tails. It also has an upper-body structure of a human, complete with opposable thumbs on its clawed hands. His current self is an old fox who lived many long years. The old fox is the strongest tailed beast with a vastly large amount of chakra and pure physical strength.

Now after many long years after Naruto's passing kurama has chosen a new host using a tailed beast sealing art to seal itself into a new host, the seal allowed the host to use new jitsu and a manifest skill that can summon a smaller version of the fox that's weaker but still strong enough to wipe a whole mountain off the map. In this form kurama is 9ft.

Kurama being a fox means he is a natural predator that is fully capable of using Vore to swallow others whole with ease to fill his belly and absorb his opponents chakra while digesting them.
