Hiruko (shinobi)

was once a great shinobi of Sunagakure. However, once he died, he became one of Sasori's first Human Puppets and one of his favorites. As a puppet, he served as Sasori's "puppet armor" as he could hide inside of him. Chiyo stated that Hiruko had changed since she saw him twenty years ago. After all of his strikes failed due to Chiyo's manipulation, Sakura Haruno destroyed the puppet.
