Akasuna no Sasori

Sasori (meaning scorpion) is a former ninja of Sunagakure. He was a legendary puppet master from Hidden Sand who left his village approximately 20 years before the start of the series. His parents died cause of the white fang (Kakashi's father) when he was young, leaving him in the care of his grandmother, Chiyo.
Lacking the love of parents, Sasori left Sunagakure when he got older and joined Akatsuki where he is initially partnered with Orochimaru. After Orochimaru's defection Sasori teamed with Deidara, who looks to him and his artistic knowledge with reverence. Sasori converted portions of his body into puppet parts, retaining a flesh and blood portion of his original self in a chest container. He used the "hitokugutsu" method to turn people into puppets while still alive, allowing him to use their jutsu even after their "death."
In time he even converted his own body into a puppet that has his heart in a container on the left side of his chest, which gives him eternal life and allows him to control hundreds of puppets at once. Each weapon in his puppets' extended arsenal is laced with a poison of Sasori's design that causes extreme pain to the inflicted until they die. He fell in battle to Chiyo and Sakura, hesitating to not avoid the lethal strike of his parents who had been made into puppets. He use “Tama” (Sphere) ring on his left thumb.
