C4

A jutsu he created to counter the Sharingan and the genjutsu it produces, Deidara uses his own mouth instead of the ones on his hands to create a giant doll in his image. When the doll ruptures, it releases a cloud of microscopic bombs then enter the bloodstream of anyone who inhales them. On Deidara's command, the mirco-bombs' detonation causes the victims' bodies to disintegrate at the cellular level; literally turning them into dust. While fighting Ōnoki, Deidara utilize an alternate method of C4 by forming a small, chibi-like clay statue of himself with the mouths in his hands.
