C0

The highest form of Deidara's Exploding Clay (his ), C0 is a suicide technique used as a last resort. He reveals a mouth on his chest, which is stitched up. After undoing the stitches, Deidara feeds it a large ball of clay. His explosive chakra then manifests itself in his veins, flowing through his body. These "veins" then condense into a sphere. The sphere then opens up and detonates, destroying everything within a ten kilometer radius.
