Shield of Sand

A technique that is unique to Gaara. Whenever Gaara is about to be harmed, a shield of sand will automatically surround and protect him. The sand will react regardless of Gaara's will, even protecting him from self-inflicted injuries. This was first believed to be enacted by Shukaku's desire to survive, although it was later revealed that it was Gaara mother's love for her son that moved the sand to protect him, thus forcibly using Shukaku's sand manipulation ability to protect her son for the rest of his life.

In Part I, the shield was formidable in both speed and strength- capable of withstanding considerably strong attacks and blocking fast projectiles. However, it could be defeated with extreme speeds and a great amount of brute force, as was the case with Rock Lee's Reverse Lotus. Later, in Part II, Gaara's sand shield became so fast that even Amaterasu failed to breach it, and his sand shield became so strong that even the extreme force of A's Guillotine Drop failed to crush through it. The Shield of Sand and the Armour of Sand together were known as Gaara's, well known and praised by even Naruto, who had just witnessed the Third Raikage's defences. Gaara can completely surround himself in the shield to further increase his defensive capabilities. 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. This formation can be used in mid-air. In Part I, Gaara can use this technique to shield himself from his opponent long enough to perform his transformation into Shukaku, though with sufficient force, this defence can be breached.

Trivia

 * Despite that Shukaku was stated to be the source of this technique, it has remained with Gaara even after the beast was extracted from his body. Both Gaara's father and uncle have stated that it is his mother's will that moves the sand to protect him and not Shukaku.
