Gaara surrounds himself with his Shield of Sand to guard against attacks. He then uses the Third Eye to watch his opponents' movements and control sand as necessary to battle them. In addition to being extremely dense, this sand-sphere can form spikes from its surface to spear any would-be attacker. Gaara can also use this technique to shield himself from his opponent long enough to perform his transformation into the One-Tailed Shukaku. With sufficient force, such as the Chidori, this defense can be broken through.
