C4

The user uses their own mouth instead of the ones on their hands to create a giant doll in their image. When the doll ruptures, it releases a cloud of microscopic bombs that enter the bloodstream of anyone who inhales them. On the user's command, the micro-bombs' detonation causes the victims' bodies to disintegrate at a cellular level; literally turning them into dust. While fighting Ōnoki, Deidara utilized an alternate method of C4 by forming a small, chibi-like clay statue of himself with the mouths in his hands.
