Even during his days as a ninja in his home town of Iwagakure , Deidara garnered high praise for his clay sculptures. However, he still desired to reach even greater heights. At first, he simply focused on creating more and more works, but before long, he started craving a forbiddened technique that was passed down in Iwagakure: a technique that allows one to knead chakra (ninja energy) into substances.He violated the law and stole the technique, causing him to be pursued. However, as the he had exploding clay used for the first time detonated and took down his pursuers, he saw the art he had desired: the Art of a single moment (一瞬の芸術, Shunshin no Geijutsu). Whenever he detonates his Exploding Clay, he recalls the process that allowed him to reach this art.This is how his exploding clay look like
The reason why like this character is that I find that his powers are very unique. I don't think there are any other super heroes or villans who have creating exploding clay as their powers. I also think that the clay he produces are very nice and yet very dangerous as during one episode he dropped a bomb, C3. Which would have tore the sand village into 2 if not for the protection of their leader. He is also a brilliant strategist. He camouflaged his explosives as sand so that he could attack the sand village's leader. Finally, I think that he is very powerful as he would not have been killed by Sasuke (naruto's best friend who went astray due to his craving of power) if not for his weakness to electricity. If you are wondering, the reason why sasuke, who was a villian attacked didera, who was also a villain was to find out where his brother, Itachi was. His catchphrase was "Art is an explosion!" and he died when he commited suicide by detonating him to form a massive yet beautiful explosion and the picture of the explosion is below. I hope now you all know why I like the character diedara.
