C0

Z0

The highest form of Deidara's explosive clay (his "SuperUltimate Art" (究極芸術, Kyūkyoku Geijutsu)), Z0/CZ is a suicide-bomb technique used as a last resort.It was only used in a non-canon filler arc. Deidara 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 that slowly cracks open and detonates, producing a unique explosion that covers half of the land of fire, land of lightning, mist village, and everything inbetween. It also sends millions of smaller C1 clay animals that explode throughout villages.

Trivia

 * The shape of the explosion bears a resemblance to Tarō Okamoto's Tower of the Sun.
