Sasori

Once a lonely child raised by his grandmother Chiyo, this legendary puppet master earned his "Red Sand" moniker through his bloodstained combat style. After murdering the Third Kazekage and fleeing Sunagakure, he joined the Akatsuki, initially partnering with Orochimaru before being paired with the volatile Deidara. To achieve near-immortality, he transformed his own body into a collection of deadly, ingenious puppets, leaving only his living heart protected within a mechanical chest.
