Hiruko (shinobi)

was once a great shinobi of the Sand Village. 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 20 years ago. After all of his strikes failed due to Chiyo's manipulation, Sakura Haruno destroyed the puppet.

Sasuke and Sai arc
Later, during the "Search for Sasuke Saga", Tenzo (under the codename Yamato) used a Hiruko disguise to fool Kabuto Yakushi into giving information on Sasori's former partner, Orochimaru. However, after Orochimaru, who had been observing the conversation the whole time, appeared before them, Kabuto revealed that he had been dispelled of Sasori's power for a while and destroyed the Hiruko disguise (though he didn't know about Tenzo being the one manipulating the puppet).
