C1
Deidara's most basic and versatile form of explosive clay, that is created from a single palm mouth. These are small animated dolls that often resemble animals. Depending upon which variation is created, they will retain the abilities of the creatures they were modelled after, i.e. those resembling birds can still fly. This feature combined with their little independent explosive power,
makes them excellent for covert operations. He can produce and release a significant number of them at high speeds.
He uses this everytime
C2
One of Deidara's specialities that requires the use of both of his palm mouths, creating a large dragon. The dragon itself is capable of flight, and, while Deidara is safely on its back, the dragon can spit out smaller clay figures that attack the opponent like guided missiles. These independent missile-like creatures take the form of a greatly reduced version of the larger dragon that created them, however, despite this decrease in size they are still relatively larger than a normal person. Each is
capable of tracking their intended target and producing a significant explosion proportional to size
upon contact but as they emerge, they consume a substantial amount of clay from the original dragon, initially extracting it from
the creature's tail. This ultimately limits the number that each C2 "Dragon" is capable of creating, before clay must be sacrificed from more vital areas, such as the body or wings. By using more
clay, the missile's size and
explosive power can be substantially increased.
Used against Kakashi and Naruto.
C3
Deidara's most powerful large
scale bomb, that once activated becomes an enormous statue that Deidara drops on his target from above. Its explosive power was
great enough to potentially
destroy a large portion of
Sunagakure. In its first known demonstration, Deidara had already prepared the explosive clay for this attack.
Once activated, the bomb
instantaneously increases its
proportions before being
subsequently dropped, where it extends both its "arms" outwards until they are completely horizontal.
C4
A technique 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 that 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 utilise an alternate method of C4 by forming a small, chibi-like clay statue of himself with the mouths in his hands.
This was used against Sasuke to counter his genjutsu.
C0
The highest form of Deidara's
explosive clay (his "Ultimate
Art" (究極芸術, Kyūkyoku Geijutsu)), C0 is a suicide-bomb
technique used as a last resort. 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 a ten kilometre blast radius.
This was used against Sasuke as his last move.
