Deidara is a missing-nin from Iwagakure and the partner of Tobi. His 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 has caused a lot of confusion, since both "he" and "she" are used to refer to Deidara. However, Deidara speaks of himself using male pronouns and has been given a very deep, male voice in the anime. Deidara also has a habit of ending his sentences with "yeah" or "hmm" (depending on the translation). Deidara has become the most popular member of Akatsuki among fans in Japan. In the most recent character popularity poll, Deidara ranked in third place, even higher than Naruto Uzumaki.
Deidara was originally teamed with Sasori, whom Deidara referred to as Master Sasori. This is probably because Deidara had a lot of respect for his fellow artist. He also admits that Sasori was a lot stronger. Despite that, Deidara still argued with Sasori about what art is and directly disobeyed his command in spite of a threat to be killed. Deidara held that art is transient, departing quickly. Sasori believed that 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!"
A fancy and skillful fighter, Deidara uses special mouths in the palm of each hand to manipulate clay into many shapes, often making animals from it. He commonly creates a flight-capable clay bird as a mode of transportation. In addition to making animals from the clay, he can make the clay explode on command. He often molds the clay into smaller animals to make sneak attacks on unsuspecting opponents. He also has a scope on his left eye for long-range observation.
Deidara's first appearance is during his mission to kidnap Gaara from Sunagakure. Deidara initially seems to be no match for Gaara's powerful sand attacks. His forearm is even torn off by Gaara's Desert Coffin. The loss of his arm actually turns out to be part of his strategy. By threatening to destroy Sunagakure with a massive clay bomb, he successfully draws Gaara's attention away from the exploding clay that he had snuck into Gaara's sand through his mangled arm. Gaara is knocked unconscious by the subsequent explosion. Deidara remarked after winning that it was typical of a Kage to save his village over his own life.
Deidara later faces off against Naruto Uzumaki and Kakashi Hatake. Deidara loses his right arm to Kakashi's Mangekyo Sharingan, which Kakashi unveils for the battle. When Team Guy arrives to assist, Deidara attempts a last ditch attack on his opponents by having one of his clay clones swallow as much clay as possible, turning it into a massive bomb. Kakashi teleported the clone away from the scene while the real Deidara escaped. Deidara later returned to locate his right arm (specifically the ring on it), only to find Zetsu and Tobi next to it. Both express surprise that Deidara had managed to survive while Sasori had not. Tobi teases Deidara about his injuries then asks if he's alright, the answer being obvious with Deidara's missing limbs. Annoyed, Deidara threatens to assign Tobi a cause of death. Tobi asks if it's death by explosion again, having apparently already been assigned a cause of death once. In response, Deidara tells him death by suffocation and proceeds to strangle Tobi with his feet in a comical fashion.
Deidara has his arms reattached by Kakuzu sometime after this point, and now has Tobi as his new partner. Deidara gets impatient with Tobi fairly easily since Tobi rarely pays attention to what he is saying. Tobi also tends to take credit for their work, despite whatever Deidara did. After they capture the three-tailed beast, Deidara lectures Tobi about being too overconfident. He becomes greatly annoyed when he discovers that Tobi has fallen asleep and proceeds to "wake him" by blasting Tobi with his exploding clay.
