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. The mouth on his chest has a direct connection to his heart so a large amount of chakra is built up. It then kneads chakra directly from the meridians of the heart and keeps doing it without interruption until the moment of the explosion. His explosive chakra then manifests itself in his veins, flowing through his body. These "veins" then condense into a sphere. The sphere will then crack open and detonates, producing a unique explosion that covers a ten kilometer radius.
