The Sky Sand Defensive Wall is a sand jutsu unique to Gaara. It works by him using a huge amount of his chakra to animate and lift an immense amount of sand from the desert and using it as a giant shield with incredible defensive capability. The jutsu was so powerful it easily blocked Deidara's C3 bomb without even receiving any damage, which amazed all onlookers. The power of it increased massively as Gaara's power did, as he could later use it to block incredibly powerful meteorites falling off the crumbling moon two years after the Fourth Great Ninja War.
