Deidara

Deidara (デイダラ, Deidara) was an S-rank missing-nin from Iwagakure. During his time in the village, he was a member of the Explosion Corps. After defecting from the village, he was forced into the Akatsuki and was one of its youngest members. There he was partnered with Sasori until the latter's death, and later with Tobi before his own death.

Background

During his time as an Iwagakure shinobi, Deidara was a pupil under the Third Tsuchikage: Ōnoki. He possessed the Explosion Release kekkei genkai which enabled him to become a member of the Explosion Corps. Though praised highly for his clay sculptures, Deidara's desire to reach even greater heights in his art, resulted with him stealing a kinjutsu that allows one to knead their chakra into substances. Using explosive clay to take out his pursuers, Deidara found the art he had desired: the Art of a Single Moment (一瞬の芸術, Isshun no Geijutsu). In the anime, Deidara left Iwagakure in shambles by blowing up several structures in the village. Remembering the first moment whenever he detonated his explosive clay, he recalls the process that allowed him to reach this art. Since then, Deidara became a missing-nin and offered his services as a bomber to insurgents in various countries.

Deidara's exploits eventually caught the attention of the Akatsuki, and Itachi Uchiha, Kisame Hoshigaki, and Sasori were sent to recruit him after Orochimaru left their organisation. Deidara refused at first until he accepts a challenge from Itachi on the condition that the Akatsuki let him be if he won. However, Deidara was easily defeated by Itachi's Sharingan and begrudgingly joined the organisation. His ego crushed since then because he admitted to himself that the Sharingan was a work of art, Deidara carried a murderous loathing for Itachi and the Sharingan for the rest of his life. Knowing that Itachi as a more powerful opponent, Deidara took steps during his time with the Akatsuki to get revenge on Itachi, such as training his left eye to counter genjutsu, and devising the means to create C4.
In the anime, Deidara and Sasori met with Hidan and Kakuzu to discuss their new missions and decide which team would take which mission. Deidara and Sasori were chosen to take the war-mission. The duo then went to the Land of This, a small nation, with the intent of destroying it to spread the Akatsuki's reputation. Deidara then handled the initial attack, setting off a series of explosion to scar the population. To his annoyance, Sasori then took over to finish the job, only agreeing because Sasori complemented his performance. By dusk, the nation was destroyed, making Sasori and Deidara's mission a success.

Personality

During his partnership with Sasori, Deidara usually showed a cool, and relaxed attitude, never losing his smirk even while fighting an intense battle or when being blamed by his partner. However, his personality seemed to change to some extent after being partnered with Tobi, as he would easily get mad at his partner’s childish and sometimes disrespectful behaviour. He also had something of a sadistic arsonist nature, rather he was not above enjoying a good fight, and he often blew up his opponents in a very brutal fashion. Deidara's most distinctive trait, however, was his love of art. He would respect any form of it, even if it disagreed with his own. Deidara also had a habit of ending his sentences with nasal-like grunts (…うん, …un), roughly translated as "yeah" or "hm". The latter of which is used in the VIZ version. Deidara also seemed to respect the ideals of others as he allowed Gaara to move the sand he used to protect his village into the desert before kidnapping him, even going so far as to admiringly call him noble.
Deidara referred to his explosive ninjutsu as art, usually quoting "Art is an Explosion!" (芸術は爆発だ, Geijutsu wa Bakuhatsu da) and seeing each bomb he made to be a significant accomplishment. He referred to his style as superflat (referring to certain types of art), and claimed pop (another art style) is dead. Deidara's pride as an artist makes him simply unwilling to accept that anything could defeat it, leading to his abandonment of strategy during his battle with Sasuke Uchiha, in favour of tactics that let him show off his art. He was able to recognise stronger opponents like Itachi, although he felt that the Sharingan was inartistic, and despised the fact that he had been enthralled by its genjutsu.
Deidara referred to his partner Sasori as Master Sasori (サソリの旦那, Sasori no Danna; English TV "Sasori, my man"), out of respect for him as a fellow artist. He also admitted, at least outwardly, that Sasori was more powerful than he was. In spite of this, Deidara wasn't above goading his partner, and they frequently argued over the nature of true art (Deidara holding that art is what lasts within a moment while Sasori believing fine art is something that lasts for all time). This reflected their individual fighting styles (Deidara made clay sculptures that exploded; Sasori made long-lasting puppets out of humans). Deidara outwardly seemed to respect Sasori's beliefs, but couldn't resist getting a final jab in after Sasori's death.
Deidara's partnership with his second partner, Tobi, however, was very different. Tobi apparently held great respect for Deidara, and frequently called him "senpai" (先輩, senior). The idiotic front Tobi put up greatly irritated Deidara, who believed that all Akatsuki members should be calm, talking less and acting serious. This in turn results in unintentionally angering Deidara to attack Tobi in a comedic fashion (e.g. blasting him with his explosive clay or strangling him with his legs). But in battle, Deidara puts his issues with Tobi aside to work well with him, telling him to get away when he was about to do a more dangerous attack. Deidara also seemed to have a minor sense of appreciation for Tobi, as shown when he apologised to his partner in his thoughts before he initiated his self-destruction technique.

Appearance

Deidara's Akatsuki attire.

Deidara had slanted blue eyes and very long blond hair which he wore drawn into a half ponytail with the rest hanging down freely. The bang hanging over his left eye is what concealed his scope signifying that he was a long-range fighter, but, as shown in his fight with Sasuke, it was not permanently attached to his face. He also had mouths in each of the palms of his hands which were used for moulding his clay and under his cloak he wore a utility belt with two bags where he carried all of his clay. Deidara had one of his arms crushed by Gaara's sand, and the elbow of his other arm was blown into another dimension by Kakashi's Kamui. Deidara had his arms restored by having Kakuzu sew what was left of his arms with what appears to be a transplanted arm. His transplant was dark brown and had several wrinkles on it. Under his cloak, he wore a V-neck, sleeveless, midriff shirt with mesh armour underneath it along with pants, stirrups, and sandals.
On the left side his chest he had a large, stitched-up mouth for setting off his self-destruct technique. On his right index finger was his Akatsuki ring, which bore the kanji for blue or green (青, ao) and was teal in colour. He wore black nail polish on his fingers and toes.

After Kabuto reincarnated him, Deidara displayed the black sclerae and darker irides seen in other reincarnated shinobi, due to the talisman placed into his head. Deidara no longer wore his forehead protector resulting in his hair being looser, although it was still kept tied into a ponytail. In place of his previous clothing, Deidara, like the other reincarnated Akatsuki members, wore a red cloak with white lining. During the anime-exclusive Chikara Arc, he originally wore a black robe with red lining before wearing the red cloak for the remaining of his servitude under Kabuto before and during the Fourth Shinobi World War.

Abilities

Deidara was a very powerful S-rank missing-nin whose abilities earned him recognition within Akatsuki, even being praised by the leader, Pain, who openly admitted that he was something unique, and that his loss was a major blow to the group. Acting on his own, Deidara was able to fight and defeat Gaara, the host of Shukaku and Fifth Kazekage, one-on-one. He also managed to fight on equal grounds against Sasuke Uchiha, a prodigy of the Uchiha clan.

Intelligence

One of Deidara's strong points was his intelligence, often using tricks, misdirection, and calculated gambles to get his explosives in range of an opponent, like he did in the fight against Gaara, putting clay into Gaara's sand as it destroyed his arm. During his battle against Sasuke, he also managed to trick him on a few occasions, such as trapping him between his C2 dragon in the sky and the landmines buried underneath the ground by Tobi, and again when he lured him into his C4 attack at point-blank. In the anime, Deidara managed to deduce a workaround to his weakness to Lightning Release by using a sword as a makeshift ground rod to siphon off the lightning-based attacks his explosive clay was weak against.
However, Deidara's obsession with his art can make him give up on strategy in exchange for tactics that allow him to show off. He was also prone to lack of preparation and recklessness as seen in his fights against Gaara and Sasuke respectively.

Nature Transformation and Explosive Clay

Deidara's explosive clay.

Deidara possessed the Explosion Release kekkei genkai. This allowed him — by simultaneously using two (currently unknown) chakra natures — to give his chakra explosive qualities. Deidara also possessed special mouths in the palms of his hands and on the left side of his chest as a result of stealing and using a powerful kinjutsu from his village on himself. By commonly using these two special abilities in unison, he could create explosive clay: clay infused with his explosive chakra that detonated with the command Katsu (喝) and the seal of confrontation. This clay could be moulded into a wide variety of shapes and forms, growing to large sizes when infused with chakra (with Deidara performing the necessary hand seals), and could be controlled at will. This allowed him to create living explosives to attack opponents at long-range.

Deidara's most powerful technique which resulted in his death.

Deidara could even create clones from the clay and named Suicide Bombing Clones, that could be a deadly surprise for opponents and if need be create clay minions to control with a cord from a distance. Deidara's clay creations ranged from microscopic to gigantic in size, allowing him to adapt to any situation from creating dragons to shoot smaller clay bombs, to working in conjunction with Obito to lay explosive clay landmines under ground to limit the opponent's movements. And, as an ultimate last resort, Deidara could turn himself into a bomb by devouring explosive clay that has a large blast radius in which he calls his "Ultimate Art". Deidara could also use the clay for other purposes, as he was frequently seen creating birds to be used for transportation which also function as a way to easily infiltrate villages on missions. It seemed he also knew standard earth-based techniques, as shown from his Earth Release: Hiding Like a Mole Technique, which he used to avoid damage from one of his mass-scale bombs. However, he could potentially run out of clay if he used too much of it, leaving him vulnerable. Since all of his explosives were earth-based, they were vulnerable to lightning, and most could thereby be defused with lightning-based attacks.
He can also create clones of himself which are incorporated into some of his techniques such as the Suicide Bombing Clone.

Eye Enhancement

Deidara's scope.

Deidara wore a scope on his left eye for long-range observation, and he had trained the eye itself to counter genjutsu, allowing him to see through and negate them. When he did this, his pupil would contract. This training was done in order to counter Itachi's powerful genjutsu skills, of which he had a considerable loathing, and wished to defeat if he got the chance. Deidara seems to be able to see long distances without his scope as after being reincarnated, he found enemy shinobi lurking near Tobi's hideout; he still needs to close his right eye in order to use his left eye for long distance vision.

Physical Prowess

As a long-range specialist, Deidara was weaker in close combat, but he was skilled enough to fend off a close combat battle against specialists like Team Guy, despite having lost both of his arms prior to their confrontation (albeit he was completely on the defensive), using only a kunai in his mouth and a variety of techniques in his arsenal to escape close-quarters when necessary. He could also avoid a blitz by Sasuke, though he noted the Uchiha's speed was too fast. Deidara also had great endurance to pain, being able to keep focused after having both his arms torn off. Along with his endurance to pain, Deidara also had great physical strength, able to pull himself free from Gaara's chakra-infused sand and sever what was left of his arm at the same time, and dislodge two giant shuriken from his arms using his feet.
