Shukaku is cunning, but also incoherent, giving it the demeanour of a madman. According to Gaara, because of its innate rage and blood-lust, Shukaku relishes the opportunity to kill anyone in sight, even more so during a full moon. Shukaku can grant its Host the power to control sand as well as allow them to transform into it in a state of need and blood-lust. Gyūki mentioned that Shukaku hates Kurama for its beliefs that the tailed beasts' strength is measured by the number of tails and, as such, views Shukaku as the weakest.
Shukaku is a sandy-brown coloured tanuki, with black markings all over its face, body, and tail. It has a jagged, concave mouth and the sclerae of its eyes are black, with yellow irides and pupils that each takes the shape of a black four-pointed star with four black dots around it. During the last days of the Sage of the Six Paths, Shukaku in its youth looked the basically same as it does presently, only much smaller.
