Sasori

Sasori of the Red Sand was a legendary puppet master from Sunagakure and a member of the Akatsuki. Orphaned as a child when his parents were killed by Sakumo Hatake, Sasori was raised by his grandmother Chiyo, who taught him the art of puppetry. His obsession with eternal beauty led him to develop human puppets — converting defeated opponents into combat puppets that retained their abilities. Sasori eventually converted his own body into a puppet, achieving a form of immortality with only his core heart container remaining as his sole human element. His most infamous achievement was single-handedly conquering a nation using his Third Kazekage puppet. Partnered with Deidara in the Akatsuki, Sasori met his end battling his grandmother Chiyo and Sakura Haruno, ultimately choosing to let himself be killed — the puppet master's final, most human act.
