Inherent Abilities:The Jinchuuriki has access to the chakra stores of his or her Bijuu, thus greatly increasing their overall capacity. They also gain an ability to move and levitate sand at will, and is protected at all times by the Shield of Sand, regardless of his will (even self-inflicted injuries are prevented by the sand). He also suffers from lifelong insomnia, a side effect of being Shukaku's host. Should he fall asleep, Shukaku would eat away at his personality.

Tailed Forms:
Note: In all tailed forms, power, defense, and stamina are increased with each stage.

• Half Tail: The Jinchuuriki transforms into a human-sized version of the Shukaku by layering sand over it’s body. The sand takes on the appearance of the Shukaku, and enhances his abilities greatly. The weak point of this transformation is at the base of its tail, where any strong enough blow (such as an exploding note) will cause severe damage to it. He can also stretch his sand limbs as he does with his regular sand, the primary difference being that his limbs remain just as strong as when they are retracted. This transformation seems to occur very slowly.
  
  
• One Tail: In desperate situations, the Jinchuuriki would instantly create a giant copy of Shukaku with himself hidden inside. While he is awake, the Jinchuuriki still has control of Shukaku's body and can fight "normally" with it. While in this form, Jinchuuriki transfers his eyesight to that of Shukaku's body in turn resulting in his own eyes losing their pupils. Unlike his smaller Shukaku form, this seems to be less able reform itself if damage, if it can at all. When the Jinchuuriki needs Shukaku's full power, he would expose his upper body on top of Shukaku's head and use the Feigning Sleep Technique, which allows Shukaku to take full control over its body. While taking over the body, Shukaku's eyes will become more apparent, changing from a simple light brown pupil, to its original version of a yellow pupil with a small black star with four blue dots around it. Shukaku can use Wind Release: Drilling Air Bullet, by pressing compressed air out of it's stomach, to cause major blunt damage to its opponents. The major weak spot of the Full Shukaku Form is as expected by the Jinchuuriki himself being Shukaku's chakra that keeps the large creation going.
  

Jutsu:

Name: Suna no Tate - Shield of the Sand
Effect: Whenever the Jinchuuriki is about to come to harm, a shield of sand will automatically surround and protect him. The sand will react regardless of the user’s will, even protecting him from self-inflicted injuries. The shield is capable of withstanding considerably strong attacks and projectiles, and can be hardened to a point where it's stronger than steel. It can be defeated by avoiding it completely with extremely high-speed attacks, or merely overcoming the shield with incredible brute force.

Name: Sunata – Sand Manipulation
Effect: The Jinchuurki possessed the ability to manipulate sand, typically moving it through the air to serve various purposes. The amount of sand he can control at one time is fairly immense, as in Part II he is able to gather enough sand to cover Sunagakure as a shield. If sand is lacking in abundance, the Jinchuuriki can break down the earth minerals in the ground to create more sand.

Name: Renkūdan - Drilling Air Bullet
Effect: Taking in a deep breath and distending his stomach, the user will punch himself in the gut, shooting large balls of compressed air and chakra at an opponent, causing an enormous conflagration if it hits. As expected from a tailed beast, this attack is very dangerous as even the large Gamabunta was in danger from the attack. The extra wind created when the attack is released is enough to raze a forest.
