Kokuo

Kokuo (also known as the Five-tails) is one of the nine tailed beast. Kokuō primarily resembles a white horse, but with a dolphin's head. It has two pointed long horns and three (two in the anime) shorter horns in front. The ends of its horns, hooves, and tails are tan, with some of the same-coloured spots before the tan areas of its horns and hooves. It also has red markings under its dark blue-green eyes.
