His favourite jutsu is the C4-jutsu where his bomb would be enlarged , and be shaped like his body but it does not explode. Its bombs would only be like a small bacteria, if inhaled would break the person inhaling it. Its an aerial technique where nobody could escape.

Deidera killed himself using an explosive C2 clay jutsu in an attempt to kill Saskue Uchiha. His obsession with his "art" (C2 clay jutsu) was his own demise. As he was fighting, Saskue mocked Deidera saying the continous fight was useless because saskue would win any way. Out of anger Deidera took his strongest clay jutsu and blew up the entire area where the fight was held blowing himself up in the process but saskue escaped using a jutsu which quickly warped him out of the area, continuing on his quest which started the fight. He was searching for the murderer of his clan, his brother Itachi Uchiha. They would soon fight to the death and in the end Itachi would die as part of Itachi's master plan to ptotect Saskue.
