Kokuō (True-Clown-Prince)

Kokuō (穆王, Kokuō), more commonly known as the Five-Tails (五尾, Gobi), is a tailed beast once sealed within from Iwagakure. It had been captured, extracted, and sealed by. After the it was returned to.

Kokuō first came into being in the waning days of the Sage of the Six Paths' life; to prevent the Ten-Tails' resurgence, the Sage split up its chakra and used his Creation of All Things (万物創造, Banbutsu Sōzō) ability to create nine separate constructs of living chakra, which would become known as the tailed beasts. Some time after being created, the Sage sat down with all the young tailed beasts and told them that they would always be together even when separated, and that one day they would become one entity again with different names as well as forms than they did then when the time came for them to understand what true power was. Kokuō eventually fell into the possession of Iwagakure and was sealed into Han.

Appearance
Kokuō primarily resembles a white horse, but with a dolphin's head. It has two pointed long horns and three shorter horns in front. The ends of its horns, hooves, and tails are light brown, with some of the same-coloured spots before the brown areas of its horns and hooves. It also has red markings under its dark blue-green eyes. During the last remaining days of the Sage of the Six Paths, Kokuō was much smaller than it is now and its horns were also shorter.
