Deidara

was a member of the Akatsuki and was partnered with Tobi and Sasori before his death.

Background
Deidara was originally from Iwagakure, although he readily abandoned the village for the opportunity of using his "art" more frequently. Deidara became an assassin bomber for hire, not caring who he worked with so long as he could use his artwork. Sometime after Orochimaru left the organization Akatsuki, Deidara was located by Itachi Uchiha, Kisame Hoshigaki, and Sasori, who were under the orders of the leader Pein to recruit him. Although, at first, Deidara refused, he quickly got into a small confrontation with Itachi, where Itachi forced Deidara to join by almost fooling Deidara into killing himself with his own clay explosives via genjutsu. Deidara, having been forced into Akatsuki and taking a huge blow to his ego, carried a loathing for Itachi throughout all of his time in Akatsuki, though he was intelligent enough to recognize Itachi as a more powerful opponent.

Personality
Quick to anger and annoy (if the right buttons are pushed), Deidara is a very hot-headed man. Something of a sadistic arsonist, he is not above relishing a good fight, and he often blows up his opponents in a very brutal fashion. Deidara's most distinctive trait, however, is his love of art. He will respect any form of it, even if it disagrees with his own. Deidara also has a habit of ending his sentences with nasal "un" sound, roughly translated as "yeah".

Deidara refers to his explosive ninjutsu as art, believing each bomb he makes to be a significant accomplishment. He refers to his style as superflat (refering to certain types of manga), and claims pop (another manga style) is dead. One of Deidara's catchphrases, "Art is a bang!" (or variations therein), was originally coined by famous Japanese abstract artist Tarō Okamoto (several of Deidara's explosives have resembled Okomoto's works too). Deidara is very proud of his art, to the point that he is simply unwilling to accept that anything could defeat it, leading to frequent overconfidence in battle.

Deidara refers to his partner Sasori as out of respect for him as a fellow artist. He also admits, at least outwardly that Sasori was more powerful than he was due to the respect he had for him. In spite of this, Deidara wasn't above goading his partner, and they frequently squabbled over the nature of true art (Deidara holding that art is transient and departing quickly; Sasori believing fine art is something wonderful that's left long into the future). This reflects their individual natures (Deidara makes clay sculptures that explode; Sasori makes long-lasting puppets out of humans). Deidara outwardly seems to respect Sasori's beliefs, but couldn't resist getting a final jab in after Sasori's death: "Like anything that is left for the future as a thing of eternal beauty... He got killed straight off!"

Deidara's partnership with his second partner Tobi, however, was very different. Tobi apparently held a great respect for Deidara and frequently called him "senpai" (senior). Tobi's carefree and goofy personality did not please Deidara, who believed that all Akatsuki members should be serious and calm. Tobi frequently and unintentionally angered Deidara, which usually resulted in him attacking Tobi in a comedic fashion (e.g., blasting him with his exploding clay or strangling him with his feet). In battle, however, the two easily set aside their differences and worked well together. Deidara also seems to have a minor respect for Tobi, as shown when he apologizes to his partner in his thoughts before he initiated his Self-Destruction.

Gender Issue
Deidara's gender is sometimes confused, due to the Japanese language's sparse use of third person pronouns, which forces translators to use their own ideas of Deidara's gender to make sentences flow smoothly. This caused a lot of confusion, since both "he" and "she" were used to refer to Deidara in early English fan translations. However, Deidara speaks of himself using male pronouns and was initially given a very deep, male voice in the anime. His current anime voice is significantly lighter, but still clearly masculine.

Rescue Gaara arc
Deidara, when partnered with Sasori, travelled to Sunagakure to capture Gaara and extract the Shukaku within him. When they got inside the village, Deidara was greeted by the Fifth Kazekage himself, and the two began to fight. Deidara's left arm was destroyed during the fight. Despite the fact that he had lost one arm, Deidara still managed to defeat the Kazekage by using the safety of Gaara's village as a distraction. Deidara then took the unconcious Gaara out of the village where his partner - Sasori was waiting. The two Akatsuki members then took their captive to their hideout where they began the three day long jutsu to extract the tailed beast out of its host while Team 7, and Team Guy attempted their rescue operation. By the time they broke into the hideout, the jutsu was completed and Gaara was dead. Naruto was enraged and began to chase after Deidara with Kakashi following him, leaving Sasori to deal with Sakura and Chiyo.

In the chase, Deidara first tried to seperate Kakashi from him and Naruto by dropping explosive clay. When the attempt failed, he simply went faster, baiting Naruto. When Kakashi revealed his Mangekyo Sharingan, destroying Deidara's right arm, Naruto finally caught up with him. Deidara dodged the attack Naruto threw towards him and Naruto's shadow clones managed to tear Deidara's clay creation(which held Gaara within it) apart. Naruto then proceeded to attack Deidara up but he only managed to destroy Deidara's Clay Clone. Deidara meanwhile hid himself and learned that Sasori was dead, killed by Sakura and Chiyo. Team Guy found out Deidara's hiding place with Neji's Byakyugan.

Outmatched by Lee and Guy's taijutsu and Tenten's long range attacks, and missing both arms, Deidara managed to escape by setting off another larger explosion by eating the clay of the remains of his clay bird (which Naruto had tore up earlier when he tried to save Gaara). Kakashi sent the explosion into another dimension using his Mangekyo Sharingan to protect the group. Deidara survived and went to find his missing arm and ring. He then became Tobi's new partner after Tobi retrieved Sasori's ring.

Deidara and Tobi arc
Deidara accompanied Tobi to capture the three-tailed beast, but noted that he did all the fighting. It is revealed in this period that Kakuzu had sewn his arms back on using his body threads.

Sasuke vs. Deidara arc
Deidara attacked Sasuke after hearing of his (seemingly) killing Orochimaru. Sasuke's lightning-elemental Chidori proved a good counter to Deidara's earth-elemental clay bombs, and Sasuke managed to survive each new bomb Deidara used against him; however, Deidara managed to counter Sasuke's newly realized genjutsu abilities by only viewing Sasuke through his left eye, which allowed him to pierce visual illusions; this led to Sasuke being forced to run his own Chidori Nagashi through his body to purge it of C4 particles, which caused him tremendous harm. Deidara created this counter to the Sharingan-based genjutsu of the Uchiha clan to defeat Itachi and found that it worked well against Sasuke. Deidara was eventually defeated, but rather than telling Sasuke where Itachi was, he decided to feed himself clay in an attempt to self-destruct and kill Sasuke. The attempt failed, though, and Deidara was killed in the blast, while Sasuke summoned Manda to protect himself at the cost of Manda's life. Later on Sasuke would find his team.

Abilities
A fancy and skillful fighter, Deidara posesses special mouths in the palm of each hand and one giant mouth on his chest, to create, chakra enfused clay that detonates on command, this usually being. This clay can be moulded into a wide variety of shapes and forms, growing to large sizes when enfused and can be controlled at will. This allows him to create living explosives to attack opponents at long range. Deidara can even create clones from the clay, named, that can be a deadly surprise for opponents. Deidara's clay creations can range from microscopic to gigantic in size, allowing him to adapt to any situation. Deidara can also use the clay for other purposes, as he is frequently seen creating birds to be used for transportation. It seems he also knows Earth Release:Inner Decapitation Technique, because he was seen underground after his suicide clone exploded. He is also seen using it during his fight with Sasuke, when Sasuke survived C4 and landed on his clay bird.

In addition to his clay based abilities, Deidara is very intelligent, often using tricks, misdirection, and calculated gambles to get his explosives in range of an opponent. Given his long range specialism he is weak at close range. He also wears a scope on his left eye for long-range observation, and he has trained the eye itself to counter genjutsu, allows him to see though and negate them. This was done in response to Itachi's powerful genjutsu skills, of which he had a considerable loathing and resolved to defeat if he got the chance. Deidara's abilities were well recognised within Akatsuki and the leader, Pein, openly admitted that he was something unique, and that his loss was a major blow to the group.

Clay Ranking
Deidara ranks his clay by number in a fashion similar to the C-4 explosive, the weakest being C1 and the most powerful being C4. The other clay ranks are much more dangerous than C1, and any foe that sees Deidara use any rank higher than C-1 is usually one Deidara sees as a worthy opponent: -
 * C-1: Deidara's most basic and versatile form of clay created from a single palm mouth. These are small animated dolls that often resemble small birds or insects. They have an explosive power similar to that of a hand grenade.  Despite being his weakest bombs they can still be lethal at close range and are very mobile and agile.
 * C-2: These are large living clay statues, created by using both palm mouths together. The best example seen was a giant dragon that could create numerous other explosives from its own body.
 * C-3 (A.K.A. Ohako): His most powerful large scale bomb, this was an large immobile clay statue that drops on targets from above. Its explosive power was great enough to apparently destroy an entire hidden village.
 * C-4: His most lethal explosive, Deidara eats and releases the clay out of his actual mouth, creating a giant copy of himself. This figure is actually a hollow shell that disintigrates, releasing a cloud of microscopic, tick-like bombs that invade the target though the lungs and the victim's skin pores and detonate inside the body, causing his victims to literally crumble to dust.


 * Ultimate Art/Self-Destruction: Deidara also has a "final attack", a suicidal technique in which he eats a large ball of clay with the mouth on his chest. This consumes his entire body, condensing the body into a large black sphere with jagged teeth and pupil-less eyes. The sphere then opens up and detonates, destroying everything within a ten kilometer radius.
