Wind Release: Sand Buckshot

After Gaara forms and compresses numerous sand bullets, Shukaku expels a giant gust of wind from its stomach to increase the force of the bullets, creating a large-scale sandstorm. This attack is powerful enough to pierce through flesh with ease, and is difficult to dodge, due to both speed and size. An additional benefit of this attack is that Gaara can then use any of the sand left in his target's bloodstream to immobilise or manipulate them, leaving them vulnerable to follow up attacks.

After the technique was used on him, Madara stated that the attack lacked a 'killing blow', however Gaara revealed the true purpose of the attack afterwards; which was to inject his sand into Madara's bloodstream, in order to both sense and manipulate him.
