Bijū
Bijū (尾獣, Tailed Beasts?) is the name used to refer to ten demons in the Naruto manga and anime. They are differentiated by the number of tails they have, which range from one to nine. Tailed beasts are living forms of chakra, sometimes referred to as Chakra Monsters (チャクラ のバケモノ, Chakura no Bakemono?), giving a ninja more power in battle. The chakra of the beasts are characterized by being red.
The immense strength that beasts possess is tempered by their bestial nature, which prevents them from being intelligent enough to use it effectively, thus when beasts are sealed within humans, they can benefit from knowledge of their users, giving them the ability to make better use of their powers. However, this has been proven to be false, tailed beasts are in fact intelligent individuals with their own personalities and emotions, and due to their power, they have been sought after by countless humans over the years, and were generally treated as mere instruments to be used, a sentiment they absolutely loathed. Furthermore, they are well aware of their origin and the state of the ninja world.
They also have the ability to communicate telepathically between themselves and their jinchūriki, and have different levels of consciousness. There is the initial level, in which the animal can appear in a species' habitat seemingly trapped, somehow, by whatever fūinjutsu sealed it away. The second level is where all tailed beasts can summon, free of restrictions. and communicate with each other. The jinchūriki can also enter there, but to do so, they must be fully connected to their demon.
Tailed beasts can also freely transfer their chakra to whomever they choose, and as Kurama pointed out, it's a less complicated process for them than it is for humans.
History
At the beginning of ninja history, centuries before the founding of the villages, there existed an entity known as the Ten-Tails, which attacked the land until the Sage of Six Paths defeated and sealed the beast within himself., becoming the first jinchūriki. However, knowing that his death would free the Ten-Tails, the sage used the creation of all things justu, to split his chakra into nine parts and create the nine tailed beasts, before using Chibaku Tensei (地爆天星, Chibaku Tensei? ) to seal his body in the moon. Time after he was created, the sage gave each of the young beasts a name and told them that they would always be together, even when they were apart. He also told them that one day they would become an entity again with a different name, as well as the forms they had at that time, when the time came for them to understand what true power was. Despite the close relationship between them, there is a lot of friction. One cause was due to Kurama's belief that his strength was determined by the number of tails.
At the time of the formation of the ninja villages, Hashirama Senju, the first Hokage, used the Wood Release to capture and deliver the various beasts to other villages as peace treaties, in order to balance power between them. each village. However, after Hashirama's death, the villages had trouble containing the beasts and began to run rampant, so the villages decided to seal the beasts within the humans. To ensure that the jinchūriki does not become a traitor, it has been common practice to choose one who is part of the family of the Kage of the village. The strength of the jinchūriki would be used to protect the village. Throughout history, very few people have gained full control of one of the beasts. Despite this, some have been able to use the power of beasts without becoming a true jinchūriki. The Gold and Silver Brothers became Kurama's pseudo-jinchūriki, having already been devoured by him, but managed to survive by consuming some of their own normally deadly flesh, tinging themselves with his chakra.
With the power of the Sharingan, Madara Uchiha was able to control the Nine-Tails and use it during his battle with Hashirama. During the fight, control of the beast was wrung out, and Madara pretended to be defeated in the Valley of the End. However, it is later revealed that he had in fact survived the fight and obtained Hashirama's DNA, his true purpose behind the fight. By integrating Hashirama's DNA into his wounds, Madara awakened the Rinnegan, just before the end of its natural life. Thanks to that, he was able to summon the Demon Statue of the Outer Path, the empty shell of the Ten-Tails.Living through the use of artificial means to expand his life, Madara was unable to carry out his plan to revive the Ten-Tails. devil. As such, he passed this goal on to Obito Uchiha, who began to share the same ideology after witnessing the death of his partner Rin.
With the help of Akatsuki, during the Fourth Ninja World War, seven of the nine tailed beasts were sealed into the statue. Later, all the beasts were sealed into their respective users, reincarnated as the Six Paths of Pain through Edo Tensei. Angered by the slow progress of the plan, Tobi, accompanied by the statue, entered the battlefield to obtain the crimson gourd and amber vessel containing the Gold and Silver Brothers. Although he did not seal Kurama and Gyuki completely, he only sealed them. possessed parts of its power, Tobi decided to start the plan when the statue undergoes a painful regeneration for the Ten-Tails. When Madara realized that the plan had started without two of the nine demons being extracted, he tried to fix this. situation. Despite Naruto and Killer Bee's attempt to destroy the statue while it was in the midst of transformation, it was successfully restored to the Ten-Tails, albeit incompletely.

Also, unlike other demons, he is capable of sucking the soul out of its wielder when the latter sleeps. Because of this, Gaara suffers from insomnia.Shukaku deeply hates Kurama because the fox bases his strength level based on the number of tails, so he considers Shukaku the weakest of all.

In the anime, a boy named Yūkimaru is able to control him through some drugs that Kabuto provided.
Unlike the other demons, he did not possess his jinchūriki at the time of his capture and is therefore very similar to a wild animal in behavior. According to Deidara, in the absence of a user, the beast is weaker as it cannot use its powers to its fullest. He is captured by Akatsuki and sealed inside the demonic statue, along with the Four-Tails.In the anime Orochimaru with Kabuto and Guren, a ninja from the Hidden Sound Village, try to capture him without success.

The two get along well in combat, so much so that Gyūki transfers her own chakra to Bee, who is able to partially and fully transform into the demon.

Kurama
Jūbi
The Ten-Tailed Beast (十尾の尾獣 , Jūbi no Bijū ?) or just Ten Tails (十尾, Jūbi ?), is the tenth and last ancestral tailed beast, the unification of all beasts. It was originally a divine tree that it contained all the chakra in the world, which humans venerated through sacred rites. Every thousand years this tree produced a fruit that no human could touch. One day, a woman, Kaguya Ōtsutsuki, ate the fruit, becoming the first living being to possess the chakra. Later the woman, now eager for power, wanted to recover the chakra inherited from her two children and for this reason she merged with the sacred tree giving life to the demon, to later attack them. Kaguya's son, Hagoromo Ōtsutsuki, better known as the Sage of the Six Paths, helped by his brother Hamura Ōtsutsuki, managed to defeat her and seal her in his body, becoming the first jinchūriki. Dying, the Sage decided to split the demon's chakra into nine parts and, through a jutsu called Creation of All Things, gave birth to nine demons into which he infused all of their mother's chakra. Eventually, he sealed the body. soulless of the Ten-Tails with the Chibaku Tensei, trapping him in a huge mass of rocks, which would later be known as the Moon.
His body was returned to Earth by Madara and was renamed the Outer Path Demon Statue, and was used as a container for the extracted demons. During the Fourth Ninja War, Obito and Madara awaken him and, after causing numerous deaths, he was first absorbed by Obito, who becomes his new jinchūriki and transforms him back into the divine tree, and then by Madara, who also absorbs the tree. Later, Madara is betrayed by the Black Zetsu, who uses him for the purpose of reviving Kaguya. After the defeat of the latter at the hands of Naruto and Sasuke, the beasts return to freedom while the demonic statue is imprisoned in a new Chibaku Tensei, thus finally ending the threat of the Ten Tails.
Being the beast the fusion of all demons or more precisely its progenitor, it preserves in its being the very essence of the entire planet. Kurama points out that it is impossible to perceive the negativity of the monster, since it is not endowed with emotions or ideals, like the energy present in the air and on the earth; however, Naruto, upon entering sage mode, realizes that the Ten-Tails' power is immeasurable. Unlike the other demons, the Ten Tails is not a sentient being since his entire existence is linked to the fact of wanting to destroy everything and everyone to take revenge for the chakra that humans stole from him. Therefore, it is the only creature that needs a jinchūriki in order to unleash its immense and unlimited potential. In conclusion, sealing the Jūbi in a human body means that the Jūbi will evolve beyond human and become a god.
