Bijū

The Biju are colossally giant beings with different types of bodies, in total there are eleven in total until the present moment of the work, each with different skills.

Origin
The Biju (or Tailed Beasts) are nine beings of colossal sizes created by Hagoromo Otsutsuki, an alien son of Kaguya Otsutsuki. Using his mother's chakra (energy) that had become the Ten-Tails, he separated it and gave them form and life, creating the Biju.

Jinchuriki
Jinchuuriki are the containers, living humans used to contain the Bijuu, which are trapped/sealed within them. A jinchuriki may eventually use the power of his Biju, but that depends, he can only use all the power of his Biju if they control it, and this can be done through a simple bond of friendship or an agreement, or if they have not done one of these procedures, Biju can also try to take care of her Jinchuuriki's body through her anger, which weakens the seal that keeps her trapped, allowing her escape, as they generally prefer to be free rather than obey orders human beings and being locked inside someone, and if a Biju is removed from its Jinchuuriki, the Jinchuriki will automatically die unless he is a Uzumaki, a group of people who have a resistance beyond normal.

Biology
Because they are nine beings created in different ways, each has unique characteristics, although they are all pieces of the Ten-Tails chakra. Each Biju has a number of tails ranging from one to nine, the more tails, the stronger the Biju.

Shukaku
The one-tailed Biju, Shukaku (also known as One-Tailed, One-Tailed Shukaku, The Sand Incarnation, Sand Shukaku and Tanuki Monster) is the weakest biju, just as all Biju have a giant size, bigger than any building in Sunagakure (the village where it resides), its body is entirely made of sand created from the chakra and has several blue marks called Cursed Seal Pattern, which can be used have a sand brown color and small ears in relation your head. It has giant hands with five pointed fingers, its tail is giant and has several parts, its eyes are black with yellow pupils and it has no neck.

Shukaku, like all Biju, can create Bijudama, giant and destructive explosive spheres made of positive and negative energy comparable to atomic bombs, it can also shoot bursts of air known as Air Release: Piercing Air Bullet and Wind Release: Dispersion of Sand Bullets. He can also use the tattoos on his body which, through physical contact, are transferred to the target making him paralyzed. As expected he can also control sand, being able to make giant pyramids called Sealing of the Great Layered Desert Funeral to attach targets, also next to his jinchuriki Gaara, he can use the Sealing Technique in the Kettle. to protect himself inside a kettle by preventing him from being tracked, but he can still interact with the outside world, manifesting his head, arms and legs out of the kettle. He can also communicate telepathically with other Biju and transfer your chakra to others, increasing their strength. It can also control magnetism and the earth.

A few millennia ago, Shukaku was sent by Hagoromo Otsutsuki to live in a temple that would protect him. During the construction of the villages of the Five Great Shinobi Lands, Shukaku was the first Biju to be captured by disciples of the temple in which he slept and sent to be trapped. in Sunagakure, where he was sealed within a priest named Bunpuku. Bunpuku was constantly locked in a dungeon with many guards, and over time, because Shukaku stayed so long inside Bunpuku, the citizens of Sunagakure came to believe that Shukaku was the ghost of an evil monk because of Shukaku's behavior. Shukaku had another unknown jinchuuriki who, using his skills, inspired the Third Kazekage to create the Iron Release technique. Over time, the Shukaku was removed from his two jinchuurikis and both died. Later, Biju was sealed in Gaara Kazekage when he had just been born, he grew up hated and feared by everyone for always fearing the power of Shukaku, Gaara grew up without knowing why people hate him and avoided him and after several traumatic events, he ended up becoming a psychopathic maniac who could use Shukaku's power "at will" for having made a kind of agreement, and even called Shukaku a mother, years later Obito Uchiha exhorted him from Madara using the Preta Path and the Etheric Touch, together with Gyuki and sealed the two on himself, and then by order of Hagoromo, in Naruto Uzumaki. Nowadays after Gaara's redemption, Shukaku has become more likable and now lives well with both humans and his brothers.

Matatabi
The two-tailed Biju, Matatabi (also called Two-Tails or Monster Cat), he is a being made entirely of blue fire created from the chakra and together with Shukaku, are the only Biju made of inorganic materials, he is quite it looks like a cat and has black marks spread all over its body, it has a mouth with sharp white teeth and a pink tongue. He has heterochromia, that is, one eye of each color being the right yellow and the left green. It has two tails with the power level just above Shukaku, it has four legs each with five fingers with sharp, long claws.

Matatabi like all Biju, can create Bijudama, giant and destructive explosive spheres made of positive and negative energy comparable to atomic bombs, it can also control blue fire by creating a technique called Scorching Flames of Hell, or spitting normal fire with a technique called Fogfire of the Flame Cat. He can also communicate telepathically with other Biju and transfer your chakra to others, increasing their strength.

A few millennia ago, Matatabi was sent by Hagoromo Otsutsuki to live in a temple that would protect him. Over the years, the world started to think that Matatabi was also a ghost of an evil man. Hashirama Senju, the first Hokage (leader of Konohagakure) with his immense power, managed to capture eight of the nine Biju, minus Shukaku for having already been captured, and in the first Meeting of the Five Kages (meeting of all the leaders of the five great nations, the Hokage, Mizukage, Tsuchikage, Raikage and Kazekage) to balance the military power of all nations and prevent a First Shinobi World War, he sold each village with Biju, so that it would not be bad for the villages. Matatabi was sold to Kumogakure along with Gyuki, the eight-tailed biju. Much later, unable to contain it, they sealed it in Yugito Nii, their first Jinchuriki who, like everyone, grew up humiliated and rejected, despite never having become like Gaara. Later Matatabi is extracted from Yugito's strength by Akatsuki, who plans to extract the Biju, from the Jinchurikis, and then fulfill Akatsuki's plan, bringing them all together to give life to the Ten-Tails monster to Juubi, resulting in the death of Yugito Nii, and later by order of Hagoromo, Matatabi is sealed in Naruto Uzumaki, and then he returned to the temple where he rested.

He can also jump while in ball form (Tower Shell Bouncing Projectile), can create a mist to hide and communicate telepathically with other biju, and transfer his chakra to other beings.

A few millennia ago, Isobu was sent by Hagoromo Otsutsuki to live in a temple that would protect him. Hashirama Senju, the first Hokage (leader of Konohagakure) with his immense power, managed to capture eight of the nine Biju, minus Shukaku for having already been captured, and in the first Meeting of the Five Kages (meeting of all the leaders of the five great nations, the Hokage, Mizukage, Tsuchikage, Raikage and Kazekage) to balance the military power of all nations and prevent a First Shinobi World War, he sold each village with Biju, so that it would not be bad for the villages. Isobu was sold to Kirigakure along with Saiken, the six-tailed bijuu. Decades later, he was sealed in Rin Nohara, with an obscure objective of ambushing them where they would kill her and in Konohagakure, causing Isobu to appear there and destroy everything, which ended up not happening because on the way there, Kakashi Hatake, Rin's best friend appears to save her, however, Rin throws himself into his Chidori, being pierced in the chest and causing his death before arriving at Konohagakure, causing irreversible trauma to Kakashi and Obito, his other friend who accidentally saw the death of Rin, who was also his beloved. All of this was orchestrated by Madara Uchiha, to make Obito a bad guy, to help him with the Eye of the Moon Plan. After being released, Isobu is again captured and sealed in Yagura Karatachi, this time with the aim of controlling him to the instead of destroying Konoha. Yagura ends up becoming the Fourth Mizukage (leader of Kirigakure) and gains complete control of Isobu but unfortunately, Obito Uchiha disguised as a masked man returns to the village that killed his beloved to have his revenge, putting Yagura in a mind control, and at the same time time controlling Isobu, causing Yagura to be extremely tyrant in his village, making her known as Blood Mist Village, several times overpowering people for revenge against the village, only years later when Ao realized this control and freed the Mizukage of him, Yagura mysteriously died and until today has not been revealed as, but it was probably suicide after knowing everything he did and that they would never accept him again. Then he was captured by Akatsuki, to recreate the Ten-Tails while resting at the bottom of a lake and later by Hagoromo's order, he was sealed in Naruto Uzumaki, and then he returned to the temple where he rested.

Son Goku
The 4-tailed bijuu, Son Goku (also known as Four-Tails, King of the Sage Monkeys, Beautiful Monkey King and Great Sage of the Unparalleled Heavens), looks very much like a red-haired monkey throughout his body except for the region of the abdomen, feet, hands, eyes, nose and ears.

Hashirama Senju, the first Hokage (leader of Konohagakure) with his immense power, managed to capture eight of the nine Biju, minus Shukaku for having already been captured, and in the first Meeting of the Five Kages (meeting of all the leaders of the five great nations, the Hokage, Mizukage, Tsuchikage, Raikage and Kazekage) to balance the military power of all nations and prevent a First Shinobi World War, he sold each village with Biju, so that it would not be bad for the villages. Son Gokū was sold to Iwagakure along with Kokuo, the five-tailed bijuu. Decades later, Son Gokū would eventually be sealed within Rōshi, who left his village on a journey to gain better understanding and control of the Biju. After a battle against Kisame Hoshigaki and Itachi Uchiha, Roshi is captured and Son Goku is taken out of Roshi, causing the death of his Jinchuriki and later by order of Hagoromo, being sealed in Naruto Uzumaki, and then he returned to the temple where he rested.

Kokuo was sold to Iwagakure along with Son Gokū, the four-tailed bijuu. Decades later, Kokuo would eventually be sealed within Han, but he ended up dying in a battle against Akatsuki and his Biju was extracted.

After its creation, Hagoromo sent Gyūki to live in a temple built with the aim of protecting it in an enclosed forest area covered with moss. Hashirama Senju, the first Hokage (leader of Konohagakure) with his immense power, managed to capture eight of the nine Biju, minus Shukaku for having already been captured, and in the first Meeting of the Five Kages (meeting of all the leaders of the five great nations, the Hokage, Mizukage, Tsuchikage, Raikage and Kazekage) to balance the military power of all nations and prevent a First Shinobi World War, he sold each village with Biju, so that it would not be bad for the villages.

Gyūki would eventually be sealed within on Blue B's father, then on his uncle, and finally on Blue B, with none succeeding in controlling him, despite this the Third Raikage continued to seal Gyuki on other Jinchurikis, until one day the beast got out of hand and the Third Raikage faced it one by one, breaking one of its horns however, leaving dead but containing the beast, this event was orchestrated by Orochimaru who gave Blue B illusion-inducing pills to extract Gyūki. Due to the pills, Gyūki had no recollection of the massacre. Gyūki was later extracted from Blue B and sealed in Killer Bee using the Iron Armor Seal when he was five years old for being considered a prodigy, later, training rigorously at the Waterfall of Truth, managed to be the first Jinchuriki to dominate Gyuki. One day Taka, a team formed by Sasuke Uchiha, Karin, Suigetsu and Jugo joins Akatsuki and tries to capture Killer Bee and extract Gyuki, however, they were being extremely humiliated in combat because Killer Bee was extremely superior, Sasuke then using his Mangekyo Sharingan, managed to defeat a fake Killer Bee clone that he had used as a distraction because he got tired of fighting and “leaving those suckers thinking he died”. During yet another Meeting of the Five Kages, Kisame Hoshigaki, one of the strongest members of Akatsuki fights Killer Bee, who uses only half of Gyuki's power, however, Kisame absorbs that power with his sword and disagrees with Killer Bee, but at that time the Raikage and his bodyguards appear and help Killer Bee to "kill" Kisame. In the countdown to the Fourth Great Ninja War, a giant squid ends up attacking the boat where Gyuki, Naruto and Yamato were, where Killer Bee turns into Gyuki and defeats squid, impressed, Naruto the current nine-tailed beast Jinchuriki asks Kurama to Killer Be training him to be able to transform into his Biju, with Killer Bee refusing but later being convinced by Gyuki.

Years later Gyuki and Killer Bee are captured by the aliens Momoshiki and Kinshiki Otsutsuki and taken to another dimension, where he steals Killer’s Gyuki chakra and Killer is thrown into a river to drown, later revealing that they both survived.

Kurama
Kurama, the nine-tailed Bijuu (also called Nine-Tails, Monster Fox and Nine-Tailed Demon Fox) is extremely similar to an orange-colored fox, with the differences that it is colossally larger, has very large ears with a band black that extends from your eyes to the tip of the ear, has scratches on the cheek and of course, nine very large tails. It is considered the strongest Bijuu of all.

Kurama like all Biju, can create Bijudama, giant and destructive explosive spheres made of positive and negative energy comparable to atomic bombs.

You can feel, detect and track chakra, the Tailed Beast's Beam, where it shoots a thin but powerful beam of energy and communicate telepathically with other Biju and transfer his chakra to others, lending his strength.

After being raised, Hagoromo sent Kurama to live in a temple built to protect him in a mountainous forest region, passou-se anos  years passed Kurama changed places, and gained fame as a being who represents the earth's natural disasters suddenly appearing to attack fertile lands and evil men, during the village formations, the Kumogakure Brothers Gold and Silver were sent to capture Kurama, failing miserably and being swallowed by the fox, however, they survived by eating the meat from the fox's stomach, thus gaining part of their powers and then being vomited. After that when Madara Uchiha, the Konohagakure leader's best friend became a renegade and fled the village, used his Sharingan to control the fox, he then returns to try to take control of the village, being confronted by Hashirama Senju, the village leader, who freed Kurama from Madara's control and "killed" him, since Kurama was too dangerous, Hashirama asked Mito Uzumaki, his seal specialist wife, to seal Kurama herself, she agrees and becomes Kurama's first Jinchuuriki. At all times, Kurama was very well contained within Mito, never had any chance to leave, as Mito never had an emotional imbalance or a weakening of the seal, aside from the time of his birth which naturally weakens the seal, but Kurama never released when he was in Mito. When it was time for her death, she passed Kurama's responsibility to Kushina Uzumaki, who was reluctant at first, but who later accepted the proposal, becoming Kurama's second jinchuriki. Later Kushina falls in love with Minato Namikaze, who becomes the Fourth Hokage. After the end of the Third Great Ninja War, Kushina would give birth to a son, which would weaken the seal, so the Third Hokage together with Kushina made the preparations, however, everything went wrong when a masked man, Obito Uchiha appears and steals the son of Kushina, Naruto Uzumaki from his arms, and promises to kill him, in the end, he does not kill him, but captures Kushina and removes the seal that trapped the fox, releasing her in Konohagakure and causing mass destruction. The Fourth Hokage and Kushina sacrificed themselves to save the village and their son, and on their last sigh, Minato separates half of Kurama's power and seals on himself, and the other half on his son, thus becoming Kurama's third Jinchuriki, and Naruto the fourth. During this attack, some of the Kurama chakra had leaked, that chakra was stored in a container and later sealed in a young apprentice ninja monk, Sora. Naruto grew up like Gaara, hated by everyone who participated in the Demon Fox Attack, without even knowing why. Although it is a tradition for the son to inherit his father's name, Naruto has the surname Uzumaki, his mother's surname to prevent his father's former enemies from recognizing the surname Namikaze and trying to kill Naruto. Despite growing up like Gaara, Naruto never became a psychopathic killer, he managed to make friends who were similar to him, who also suffered from loneliness. The next time Kurama appears was on the first mission of Naruto and his team outside his village, where to avenge his supposedly dead friend, Naruto uses a small portion of the nine-tailed chakra to kill Haku, the one who had supposedly killed his friend Sasuke. In the Attack of Pain, the Akatsuki boss, wanted to capture and extract Naruto's Kurama, Naruto was the only one who could stop him, but his power was not enough, so after seeing his friend Hinata Hyuga sacrificing himself to prevent his death, his anger over the highest levels and he unleashes power from four of Kurama's nine tails at once, instead of releasing one at a time as he did before. The number of tails of Naruto grew very fast, and with a few minutes of fighting, he already had seven tails, if the number reaches nine, Naruto will be killed and Kurama will be free. Pain was no longer taking the fight and tried to seal Naruto in his Chibaku Tensei, trapping him in the center of a giant satellite, which was in vain, Naruto already had eight tails and that power was enough to get out of there, until that at the last minute, Minato Namikaze, his father, appears to stop Naruto who inside his subconscious was about to release Kurama completely, he tells Naruto not to worry because the hatred of the fox will always be overcome if he remembers that he is not alone, he remakes the seal, and returning to normal, Naruto convinces Nagato, the one who was controlling Pain to resurrect everyone he killed and regret his mistakes. In the Countdown to the Fourth Great Ninja War, Naruto training with Killer Bee, a jinchuuriki who knew how to control his beast, needs to defeat Kurama in a fight, where Kurama almost takes control of Naruto, however, his mother Kushina appears who advises him, after that he defeats her, Kurama disappears into his subconscious and says he will never forget that defeat. In the Confrontation of the Fourth Great Ninja War, Kurama calls his jinchuuriki into his subconscious and tries to persuade him to use his chakra, so that he can take control. She also says that Naruto's attempt to stop his friend's hatred is futile, and will never work. Angry Naruto, catches Kurama on the Torii Seal and says that one day, he will not only end his friend's war and hatred, but also Kurama's own hatred. In the climax of the Fourth Great Ninja War, Madara Uchiha reincarnated in her own body, tries to summon Kurama with her fight against Hashirama, but fails because she is protected by a seal inside Naruto, which makes Madara realize who Jinchuuriki is, Kurama recognizes Madara's chakra trying to summon her, and tells Naruto that this would be the strongest enemy he has ever faced and tries to lend some of his chakra to Naruto, this time without the goal of taking care of his body, claiming who prefers to help Naruto rather than serve Madara, later in a fight against the reincarnated Jinchurikis Akatsuki had killed, Kurama seeing that Naruto was struggling, decides to lend more of his chakra to Naruto, Naruto says that he really recognizes Kurama as one valuable companion, then opening the seal that held Kurama trapped, finally being able to use all of Kurama's power at no cost. At the Birth of Jinchūriki of the Ten-Tails, Minato Namikaze the father of Naruto, reincarnated, shares the chakra of the half of the Kurama that was sealed in it with that of Naruto, and vice versa, making the two much stronger than they were, later, Madara summons the Demonic Statue of the Outer Path, which repels the Biju which repels all the Biju, and Madara quickly chains them and begins to steal his entire chakra, if he continued, Kurama would be extracted from naruto and he would die, then, Kurama tells Gaara to speak in order for Minato to transfer his part of the fox to Naruto, however, Black Zetsu falls between Minato and Naruto, causing Kurama to be transferred to black Zetsu, becoming his Jinchuriki. Black Zetsu tries to return to Madara, however, he was sharing a body with Obito, who decides to help Naruto, taking Naruto and himself to another dimension, where he transfers Kurama to Naruto. Long after the war was over and everything was at peace, Toneri's plan for the Fall of the Moon begins, Naruto then goes to the Moon to stop Toneri, who summons a giant golem, causing Kurama to fight against him. When they beat Toneri, Kurama writes in very large letters on the Moon, "Complete Mission" for everyone on Earth. Years later, in a fight against Shin Uchiha and his sons, Naruto is stabbed by one of his sons, who makes this son enter his subconscious, visiting Kurama with an extremely frightening face, making all his children surrender. Nowadays in a fight against Isshiki Otsutsuki, Naruto and Sasuke the two strongest men alive are being slaughtered by the alien, Kurama then says that he has a hope, a new transformation combined with it, however this may cause his death, Naruto says that he does not cares about it and turns. (It was not revealed what happens next, we have to wait for the next chapter)

Ten-Tails
The Ten-Tails (also called Jubi, God of an Eye, Datara or Deidarabotchi) is the seed of a Divine Tree, a tree that absorbs all the energy on the planet and turns it into a fruit. The tree is planted by an Otsutsuki on one planet and fed by another, when the tree grows, the seed comes off becoming the Ten-Tails, in which case, when Kaguya arrived on Earth with Isshiki to pick up the fruit, Kaguya ate the fruit later, when her children turn against her, she absorbs the power of the tree and becomes the Ten-Tails, until today we don't know how it happened. When she became the Juubi, Hagoromo and Hamura defeated her and Hagoromo separated her chakra into nine parts, creating the Biju, and her body became the Demonic Statue of the Outer Path and went with Hamura to the Moon. the Biju and depositing inside the statue, she becomes Juubi again, the strongest Biju of all, she has several forms, among them:

Millennia ago, a Divine Tree was planted on Earth, which ended up being venerated as a deity, every thousand years a fruit was generated, and although it was forbidden to consume the fruit, Kaguya Otsutsuki ate it to end a war, winning immeasurable power and putting everyone in an illusion. After her children discover what she has done and turn against her, Kaguya goes crazy from the head and absorbs the Divine Tree, becoming the Ten-Tails and fighting for months against her children, ending with the Ten-Tails' body sealed on the Moon, and its chakra being separated into 9 parts, creating the Biju. Millennia later, Madara and Obito Uchiha manipulated by Zetsu, a herald from Kaguya, created Akatsuki, a group to gather the Biju and deposit them in the Demonic Statue of the Outer Path, which is the body of the Ten-Tails, to bring Kaguya from return. They carry out the plan but only get fragments of the chakra of Gyuki and Kurama, so to compensate, Obito hands Benihisago and Kohaku no Jōhei, two weapons made by Kaguya's son, making the Ten-Tails transformation process begin. With the rebirth complete, Obito and Madara jump on top of the Ten-Tails and connect two cables around their neck to control it, and begin to test the powers of the beast, fighting against Gyuki, Kurama, Naruto, Kakashi, and the entire Alliance Shinobi. Already in her 2nd form and with Madara and Obito using Hashirama cells to improve control, she seemed invincible, but then after Naruto Uzumaki distributed his immeasurable amount of chakra combined with the Kurama chakra to all the shinobi of the war, the Nara clan specializing in paralyzing enemies through its shadow finally manages to contain the Ten-Tails, and Naruto with his Rasenshuriken rips off two of the ten tails of the beast, taking Madara and Obito out of her control, and now on its own will, Ten-Tails creates several natural disasters around her decimating everything around her, after feeling Naruto’s immeasurable chakra united with seven other Biju, she remembers her fight against Kaguya’s children, launching a much larger than normal Bijudama and launching her, destroying all the barriers that had been erected by the Alliance, however, it ends up being teleported by Minato Namikaze, after he arrives at the battlefield. After the four previous Hokages (leaders of the leaf village), the strongest shinobi that ever existed, they meet with Hashirama creating a barrier around Ten-Tails, she knowing she wouldn't run away easily, creates mini clones to fight them. Obito emerges from another dimension and I fell on top of Ten-Tails, which makes Madara try to control Obito so that he can resurrect Madara, since he was just reincarnated, Obito refuses and seals the Ten-Tails within himself, becoming his second Jinchuriki. Ten-Tails makes Obito suffer psychologically thanks to his immense power, however, he manages to control the power of the beast, Obito then projects the Ten-Tails out of himself and turns it into the Divine Tree, making the tree suck the energy of everyone present, speeding up the process of generating a fruit, but Naruto intervenes and together with Garra and Killer Bee, they manage to get all the Biju out of the Ten-Tails, preventing the birth of the fruit. Madara later manages to reseal the Biju inside the Statue, causing the Ten-Tails to be reborn and sealing it inside, becoming his new Jinchuriki, thus launching the Tsukoyomi INfinite on the Moon, trapping the world in a reality of endless dreams, where there would be nothing bad and after doing that, he is betrayed by Zetsu Negro, who uses Madara to absorb the chakra of the victims of the Infinite Tsukoyomi, making him transform into Kaguya, which transports Kakashi, Obito, Sasuke, Sakura and Naruto to a another dimension and starts a battle, which is finally sealed again by Sasuke and Naruto, ending the war and this Ten-Tails.

Isshiki's Ten-Tails
This is the most recent Biju and it is not part of the Biju made by Hagoromo, since the Ten-Tails are seeds of Divine Trees, there are many Ten-Tails spread around the worlds and this is one of them. Isshiki is a member of the Otsutsuki clan, an alien family from another dimension, who is said to be a Biju. It is similar to Earth's Ten-Tails, however, much smaller in size and has human-like teeth, it has small horns on its head.

The only skill she showed was Rinnegan, a technique that makes her iris purple with a pattern of black circles, gives her the ability to identify chakra, but she cannot see through things that obstruct her vision, she can recognize codes and languages that you don’t know and learn to use all five elements fire, water, lightning, earth and wind, even though she didn’t show any of Rinnegan’s skills.

She was first seen by Sasuke Uchiha as an adult, who was after information about the Otsutsuki and ended up finding Isshiki's Ten-Tails in the basement of an altar, before he could see with delicacy, a portal opens there, it was Isshiki that absorbs an amount of Ten-Tails chakra, indicating that he uses it as a source of power.
