The Five-Tailed Horse, or Kokuo (The name given by the Sage of Six Paths), is one of the nine Bijuus in Naruto. It has made no appearance at all in the series but has been mentioned. It is one of the two bijuus that have been captured before the start of Part II.
Nothing is known about the Tailed Beast but like other bijuus it is assumed to have enormous amounts of chakra and brute strength with also the ability to use the Tailed-Beast Ball.
