Hiruko (shinobi)

is a puppet used by the Akatsuki ninja, Sasori. As a puppet, he served as Sasori's "puppet armor", as Sasori was capable of hiding inside of it. Sasori even adorned Hiruko with the Akatsuki's robes, and hid inside it so often that others came to recognize him only when he was wearing it.

Chiyo stated that Hiruko had changed since she saw it twenty years ago. After all of it's strikes failed due to Chiyo's manipulation, Sakura Haruno destroyed the puppet.
