Who Is Gyūki?

Registry summary

Gyūki is the Eight-Tails, the second strongest of the nine tailed beasts. An ox-headed, octopus-bodied creature once infamous in Kumogakure for its rampages, it became — in Killer B — the first tailed beast in history to truly befriend its jinchūriki, a partnership that would later be the model for Naruto and Kurama.

Dossier · 03Origins

Background & Origins

Gyūki is one of the nine tailed beasts, created when Hagoromo Ōtsutsuki split the chakra of the Ten-Tails into nine separate creatures and gave each a name.

Its form is an ushi-oni — a creature out of folklore with the horned head of a bull and the body of an octopus, its lower half made of eight tentacle tails.

For a long time, Gyūki was infamous in Kumogakure. Every host before Killer B failed to control it, and the Eight-Tails rampaged each time — a beast that hated the humans who kept sealing it away.

Gyūki: Story Arc

  1. Born of the Ten-TailsDebut Arc · Five Kage Summit

    Named by the Sage

    Gyūki comes into being when Hagoromo Ōtsutsuki divides the Ten-Tails into nine beasts. Like its siblings, it is given a name and a self — not made a weapon, but made a being.

  2. The violent years

    The beast that rampaged

    For generations, Gyūki is infamous in Kumogakure. Every jinchūriki before Killer B loses control of it, and the Eight-Tails rampages — a creature whose hatred of its captors only deepens.

  3. Sealed and warring

    Passed from cage to cage

    Gyūki is sealed, broken loose, and sealed again, host after host. To the Eight-Tails, humans are only the ones who chain it — and it gives them, in return, only its rage.

  4. Bested by Killer B

    Beaten, and then respected

    Killer B defeats Gyūki in single combat — and then does what no host had: he treats the Eight-Tails as a partner, not a weapon. It is the first time anyone has offered it that.

  5. The first true partnership

    A beast with a friend

    Gyūki and B become genuine friends — the first willing partnership in history between a tailed beast and its jinchūriki. The rampaging Eight-Tails becomes calm, dry-humoured, and loyal.

  6. The war, side by side

    The model for Naruto

    Gyūki and B fight the Fourth Shinobi World War as one — and together they teach Naruto the same lesson, the bond that would let him reach the Nine-Tails in turn.

Dossier · 05Combat

Abilities & Signature Jutsu

Gyūki is the second strongest of the nine tailed beasts, and it fights with a tactician's head as much as a beast's power. It can fire the Tailed Beast Ball in volleys, as a wave, or supercharged to many times its size; it strikes and shields with eight octopus-arm tails; and, true to its form, it produces ink to blind enemies or shape into clones. It is also clever enough to coach its jinchūriki through a fight in real time.

Debut

Itachi Pursuit & Sasuke vs Itachi

Gyūki's Tailed Beast attribute is the giveaway — a column hit that only the nine tailed beasts on the board share. Its Village column reads None and its Ninja Rank reads None, and it has no clan and no Kekkei Genkai, so four columns turn grey at once. Its Nature Types column runs Water, Lightning, and Yang. It debuts in the Five Kage Summit era, a late arc, so the Debut Arc arrow points up toward it.
