Sasori is a master of the art of puppets. not only is his body a puppet, but he can create puppets made from other humans and harness their Bloodline traits, keeping them in such a way that the puppet can use the original ninja's bloodline techniques.
The Legend of Everlasting Art.
At the start of Part II, Sasori, hidden in his puppet, Hiruko, returned to his former village, Sunagakure, with Deidara to capture the One-Tailed Shukaku's jinchūriki, and the Fifth Kazekage, Gaara. Both the Akatsuki members easily penetrated Suna's defences, as the village was betrayed by one of Sasori's own subordinates, Yūra. After Deidara captured Gaara, the Kazekage's elder brother, Kankurō, attempted to stop the Akatsuki duo from fleeing. But Sasori confronted him so that Deidara could go on ahead unopposed and made quick work of Kankurō, poisoning and nearly killing him, and easily destroying his puppets, as he had pre-existing knowledge of their secrets. After the Akatsuki members extracted and sealed the One-Tailed Shukaku from Gaara at the Akatsuki hideout, Sasori and Deidara were left in charge by their leader of defeating the pursuing Team 7 and Sasori's grandmother, Chiyo. As Deidara led Naruto Uzumaki and Kakashi Hatake away using Gaara's dead body as bait, Sasori was left to face Sakura Haruno and his grandmother Chiyo.

Soon after the battle began, with Chiyo controlling her as a puppet, Sakura was able to destroy Sasori's puppet, Hiruko. As Sasori emerged from Hiruko's remains and revealed his true self, Chiyo and Sakura were shocked to see his youthful face, considering that he had left Sunagakure over twenty years ago. Not wasting any time, however, Sasori brought out his Third Kazekage puppet, who he revealed to be his favourite, as the Third was the hardest to kill and add to his collection. Since the Third Kazekage was a human puppet, Sasori was able use its various Iron Sand abilities to attack and overwhelm Chiyo and Sakura. To try and combat the Kazekage, Chiyo brought out the first puppets Sasori ever created Mother and Father. Although Chiyo had since equipped them with extra weapons and defences, the Kazekage's puppet's Iron Sand quickly disabled the two puppets, and Chiyo's arm as well. Acting on her own, Sakura demolished the Kazekage puppet after picking up on its movements and using herself as bait to lower Sasori's guard.

With the loss of the Kazekage puppet, Sasori revealed the reason behind his eternal youth: his own human puppet body, which itself was fitted with numerous weapons and traps laced with poison. Sakura eventually managed to break apart his puppet body, but missed his core, allowing him to reassemble himself. Chiyo then brought out her own ten puppets in an attempt to level the playing field. Sasori used his Red Secret Technique: Performance of a Hundred Puppets, allowing him to control ten times as many puppets as Chiyo. Since Chiyo's puppets were designed to work together, a trait lacking with all of Sasori's puppets, her puppets fared far better than his, although they were eventually overwhelmed by Sasori's sheer numbers. During the battle, Chiyo attempted to seal Sasori's chakra with a special orb from one of her puppets, but missed his core — the only living part of his body and the source of his chakra — and only trapped his puppet body. As Chiyo and Sakura were distracted by his summoned puppets, Sasori was revealed to have transferred the cylindrical container housing his core, into another one of his own puppets, possessing his face's likeness, before the seal nailed his original body to a wall.

Using the seal as a distraction, Sasori, in his new puppet body, attempted a sneak attack on Chiyo. However, Sakura took the sword's attack from Sasori for Chiyo. Sasori's katana pierced Sakura's abdomen, and since the blade itself was coated in poison, Sasori stated that she would either succumb to the poison or bleed to death.

Sasori had the same birth date as Masashi Kishimoto.
