Abilities
Like all tailed beasts, Shukaku has an enormous supply of chakra compared to most ninja. However, it does not have as much as the Nine-Tailed Demon Fox. Shukaku has the power over wind, in which it uses to perform powerful attacks such as the Wind Release: Drilling Air Bullet; the ability to manipulate sand, using it as an effective weapon; and can perform the Tailed Beast Ball. At fully-released form, Shukaku's body is completely made of sand; as such he can ignore most damage that would otherwise be detrimental, as shown when he had one of his arms chopped off by Gamabunta and was still able to keep on fighting. Whenever Shukaku is sealed into its jinchūriki, it has the ability to eat away its host's personality, and influence him or her with its bloodlust behaviour whenever he or she sleeps, which leads its host to develop insomnia.
Activity inside Gaara
Main article: Gaara's Jinchūriki Forms As Shukaku's jinchūriki, Gaara has the ability to move and levitate sand at will. Shukaku was at first believed to be the source of the automatic Shield of Sand, however the Fourth Kazekage told Gaara that this was due to his mother's will being in the sand. When angry or in a state of bloodlust, Gaara can use the sand in his gourd to take on the form of a miniature Shukaku, or even create a giant copy of Shukaku's body.
