Ultimately Hard Absolute Defence: Shield of Shukaku

This defensive technique is formed by Gaara to create a toy-like replica of Shukaku wearing a wide-brimmed rural hat, that is roughly thrice the size of Gaara. Because the replica is formed under extreme pressure and is built of the strongest minerals Gaara could derive from the earth, it is virtually indestructible, having yet to be penetrated by any force. As the name of the technique implies, this is Gaara's strongest defence.

Trivia

 * In the anime, the attack variant of the Shield of Shukaku is the Ultimately Hard Absolute Attack: Spear of Shukaku.
