The nine tailed beasts and their most recent jinchūriki.

The tailed beasts (尾獣, bijū), sometimes referred to as "Chakra Monsters" (チャクラのバケモノ, Chakura no Bakemono),[1] are the nine titanic living forms of chakra created by the Sage of the Six Paths.[2][3] They are differentiated by the number of tails they have, ranging from one to nine.

The young tailed beasts with the Sage of the Six Paths.

Long before the founding of the hidden villages, the Sage of the Six Paths saved the world by sealing the Ten-Tails into his body, becoming its jinchūriki. Sometime later, the Sage was inspired by his youngest son, Asura, to use his Creation of All Things ability to divide the Ten-Tails' chakra into nine living entities, what would become the tailed beasts.[4][5] The Sage named the nine and explained to them 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.[6] After the Sage's death, the tailed beasts drifted apart, apparently due to Kurama's belief that their number of tails was an indication of their strength.[7]

Over the centuries, humanity failed to recognise the tailed beasts as sapient individuals, instead seeing them only as monsters, demons, or mindless beasts worthy of fear and disdain. Because of their immense power, the tailed beasts were sought out by humans to be used as weapons in times of war. The beasts resented this treatment and came to hate humans, at times willingly becoming the monsters they were viewed as.[8] Shortly after the hidden villages were created, Hashirama Senju, who had captured several of the tailed beasts with his Wood Release, distributed the beasts amongst the new villages in order to stabilise the balance of power between them.[9] In order to harness the beasts' power, the villages began sealing them into humans, creating their own jinchūriki.

Decades later, after the Third Shinobi World War, an organisation known as Akatsuki begins capturing the villages' jinchūriki in order to extract their tailed beasts and seal them into the Demonic Statue of the Outer Path for the purposes of reviving the Ten-Tails. By the time of the Fourth Shinobi World War, Akatsuki has captured the first seven tailed beasts.[10] In order to capture the last two, the Eight-Tails and Nine-Tails, Tobi seals the beasts back into their reincarnated jinchūriki and forces them to fight the Eight-Tails' and Nine-Tails' jinchūriki: Killer B and Naruto Uzumaki, respectively. From Naruto's determination to free them from Tobi and his desire to learn their names, the tailed beasts collectively decide that Naruto is the person the Sage of Six Paths foretold of. They give him portions of their chakra, enabling him to release them from Tobi's control.

Tailed Beast Reunion

The tailed beasts reunite with Hagoromo and Naruto.

Tobi is able to reclaim the freed tailed beasts and, using fragments of the Eight-Tails and Nine-Tails' chakra,[11] prematurely revives the Ten-Tails.[12] Tobi then becomes the Ten-Tails' jinchūriki, but he is defeated by the Allied Shinobi Forces and the tailed beasts are removed from his body.[13] The nine tailed beasts join forces against Tobi's co-conspirator, Madara Uchiha, but he quickly defeats them all and seals them, including the Eight-Tails and Nine-Tails, into the Demonic Statue and reforms the Ten-Tails yet again.[14] Madara becomes the Ten-Tails' jinchūriki and attempts to use Infinite Tsukuyomi on the world. Naruto uses the tailed beasts' earlier donations of chakra to try and defeat him, but is unable to do so in time. Madara is afterwards unwittingly used to restore Kaguya Ōtsutsuki, who tries to take what portions of the tailed beasts' chakra Naruto still has.

In one of Kaguya's dimensions, Naruto and Sasuke Uchiha seal Kaguya away and the tailed beasts are extracted from her body, ending the war. Sasuke, however, realising that the struggle for the tailed beasts started the war in the first place, imprisons them with Chibaku Tensei and intends to kill them so the world can't fight over them any longer. Naruto convinces him not to in the end and the tailed beasts are finally released for good.[15] The tailed beasts spread out through the world, free to live as they want; both Gyūki and Kurama decide to return and stay with B and Naruto. However, though they are apart, the tailed beasts' chakra fragments remain within Naruto, allowing his body to act as their "meeting ground".[16]


Tailed Beast Balls

Tailed beasts are widely believed to be bestial in nature, incapable of the intelligence needed to fully utilise their immense strength. It is thought that only when sealed within humans are they able to benefit from the knowledge of their jinchūriki to use their powers effectively.[17] This is not actually true. However, unless sealed within a human, tailed beasts tend to make wanton use of their powers, not focusing their abilities towards whatever end would be most advantageous to them.[18]

Each of the tailed beasts have their own unique abilities, but they all share the same attributes: they have massive quantities of powerful chakra - coloured red - far greater than what most shinobi have, can easily transfer their chakra to whomever they choose,[19] and can use the Tailed Beast Ball.[20] Because the tailed beasts are pure chakra, they cannot actually be killed; if they or their jinchūriki die, their chakra will re-coalesce in time.[21] In addition, if a large portion of a tailed beast's chakra is separated from it, that chakra becomes a separate, sentient copy of the tailed beast.[22]

Tailed beasts can communicate telepathically with one another and their jinchūriki, and possess several levels of consciousness. In the initial level, the beast appears to be in a habitat of sorts, typically imprisoned in some way by whatever fūinjutsu was used to seal them.[23][24] The second level is where all the tailed beasts can convene and communicate with one another, free of any restrictions. Jinchūriki are also able to enter this level, but in order to do so, they must be completely linked with their tailed beasts.[25]

The Tailed Beasts

The tailed beasts in order of their number of tails:

  1. Shukaku
  2. Matatabi
  3. Isobu
  4. Son Gokū
  5. Kokuō
  6. Saiken
  7. Chōmei
  8. Gyūki
  9. Kurama
  10. Ten-Tails

Similar Cases


  • Shukaku, Matatabi, Gyūki, and Kurama are based on popular animal yōkai from Japanese myth (tanuki, nekomata, ushi-oni, and kitsune respectively). The others are original creations by Masashi Kishimoto, mixing together various elements from certain species of animals.
  • While most of the tailed beasts have conventional tails, Chōmei and Gyūki differ; Chōmei has one regular tail and six wings that make up its seven tails, while Gyūki has eight cephalopod limbs that serve as tails.
  • Despite having names, the tailed beasts do not generally use them, either for themselves or for each other, instead referring to each other by how many tails they have. Son Gokū is the only consistent exception, taking offence to the monikers.
  • There have been cases that both the tailed beasts and their jinchūriki are affected to a certain degree during a full moon:
    • According to Gaara, Shukaku's blood-lust is especially strong during a full moon.[26]
    • In the anime, Blue B, during his time as Gyūki's jinchūriki, noted that he would have trouble sleeping during the nights of the full moon, because anytime he would stare at it, it would reflect the loneliness in his heart. Gyūki would take advantage of those moments of weakness and try to control over Blue B's body. Blue B was also shown to take sleeping pills to help with this side-effect.[27]
  • Several non-jinchūriki shinobi have been said to hold chakra levels or strength comparable to that of a tailed beast. Such individuals include Kisame Hoshigaki,[28] Madara Uchiha,[29] Hashirama Senju, the Third Raikage, and the Fourth Raikage.
  • In the anime, the six tailed beasts that were used by Tobi shared a voice actor with one of each other's respective jinchūriki.
  • How the tailed beasts speak has been depicted inconsistently throughout the series, where sometimes their mouths move with their words and sometimes they don't.
