Kurama

Kurama , more commonly known as the Nine-Tails , was 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 overturns its hatred and willingly strives to use its power for the world's salvation. 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 giving each a name. Some time 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.In the anime, 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. During the time of the founding of the shinobi villages, the Gold and Silver Brothers of Kumogakure were assigned to capture Kurama, but were both swallowed whole by the fox. However, the two brothers survived and gained some of its power by eating the flesh of its stomach for two weeks, forcing Kurama to regurgitate them. 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 period of time which included the first two 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 her life, Mito passed on this status and responsibility to another member of her clan, Kushina Uzumaki, who later became the wife of Minato Namikaze, the Fourth Hokage. Although Kushina was terrified with the responsibility of containing Kurama, Mito assured her successor that the fox's hatred was powerless against her love. 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 Kurama's chakra was too immense to be sealed within an infant, Minato first used the Dead Demon Consuming Seal to separate and seal its 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. Later, upon awakening within Naruto's subconscious and learning the reason behind Minato's intention, Yang-Kurama, though frustrated of being sealed again, decided to wait for the time to come when it would influence Naruto as much as it can to use its power to break the seal. Throughout the years, Kurama weakened the seal through the cracks of its formation by constantly leaking 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. In the anime, it was revealed that Kurama had left behind large amounts of its chakra during the attack. Kazuma, a former member of the Twelve Guardian Ninja, collected and sealed the chakra within his son, Sora, hoping to make use of its power for his own agenda. Kurama is widely known as the strongest of the nine tailed beasts. Hashirama Senju, who could subdue the fox, viewed it as too powerful and dangerous to be left roaming free. Even with only half its power, Kurama remained strong enough to defeat five other tailed beasts at the same time. After the Fourth Shinobi World War, Kurama's full power was restored once its two halves reunited inside Naruto, which could defeat Toneri's giant golem and Momoshiki Ōtsutsuki's elemental construct.[ Kurama later became able to manifest itself outside of Naruto, allowing the two to fight independently and away from each other. Even for a tailed beast, Kurama possesses massive reserves of powerful chakra, required to be sealed last into the Demonic Statue of the Outer Path to avoid overloading it. It can also accumulate a huge amount of chakra shortly after it has used up most of its own, enough to be passed on to the entire Allied Shinobi Forces and be felt countries away by non-sensors. Due to Naruto's compatibility with Kurama's chakra, any chakra it possesses is limited for its jinchūriki alone, unless it was moulded to fit the recipient's unique chakra signature. When used by others, the chakra becomes dense enough to be seen as a visible shroud than can further protect the wearer. Using its chakra, Kurama can shroud itself within its Nine-Tails Chakra Mode to increase its power. As a last-ditch ability, Kurama can enter Baryon Mode. In this state, similar to nuclear fusion, Kurama's chakra is consumed as raw materials to produce a new type of energy. When in use, it dramatically boosts Kurama's reflexes, raw might, and charka to extreme levels. Because all chakra is connected, the same power that is produced from bits of their lives also works to reduce the lifespan of opponents on contact. Due to its extreme energy consumption, Kurama must remain focused and not waste energy of extraneous thoughts and actions, to maximise the amount of time Baryon Mode can be maintained. Kurama has a great deal of brute force, reputedly able to raise tsunamis and flatten mountains with just a single swipe of a tail. Even with half its strength, it could overpower Obito's controlled tailed beasts, smash Madara's senjutsu-enhanced Susanoo with a tail, and with the Six Paths Chakra, battle Sasuke's Tailed Beast-enhanced Complete Body — Susanoo. Kurama is deceptively quite fast, able to catch Naruto in Sage Mode. The fox is also durable enough to withstand several senjutsu-enhanced attacks, and block a Tailed Beast Ball from the Ten-Tails' initial form. As a tailed beast, Kurama can create a Tailed Beast Ball, and is able to fire it as a beam or rapid blast of spheres. Unlike most tailed beasts, Kurama can supercharge it, creating one many times its own size for much greater power, even on low chakra. One of these was powerful enough to counter a collaborated Tailed Beast Ball from five tailed beasts. At full power, Kurama's Tailed Beast Ball could blast Toneri's giant golem through the moon and into orbit. Kurama can create destructive shockwaves, capable of dispersing a massive Rasengan, knocking back five tailed beasts at once, and destroying entire city blocks as shown when he used it against Konoha. Even when limited through Naruto's Version 1 and 2 states, they were strong enough to destroy an entire bridge and repel Pain's Shinra Tensei respectively. Kurama also had adept sensor skills, able to detect chakra from great distances and uniquely able to sense negative emotions, as well as natural energy, which it can accumulate and transfer to Naruto to create senjutsu chakra. In the anime, it is shown using Wind and Fire Release nature transformations, being able to generate twisters and breathe fire. Kurama is very cunning and can formulate strategies in the midst of battle. Through Naruto's body, the fox tricked Obito into using Kamui to absorb Kakashi into Kamui's dimension, only for Obito to become vulnerable to Kakashi's attacks as he phased through Naruto's punch. Kurama has also shown remarkable leadership skills, being able to calmly and effectively instruct its allies on how best to engage the Ten-Tails. In the anime, it has enough knowledge of fūinjutsu to determine the natures and weaknesses of the Eight Trigrams Seal that bound it inside Naruto. In addition, Kurama has an advanced understanding of nuclear physics, particularly the nuclear fusion that occurs within the Sun.
