Shukaku and the tailed beasts first came into being in the waning days of Hagoromo Ōtsutsuki, who used his Creation of All Things Technique to divide the Ten-Tails' chakra into nine separate bodies and giving each a name. Shukaku is characterised as a childish and short-tempered individual, and often speaks in a bombastic and incoherent manner. Shukau's very prideful of its own abilities. Shukaku can use Earthand Wind release, and a unique power named Magnet Release.
