Black Receiver

Nagato implanted chakra receivers into each of his Six Paths of Pain as body piercings. Doing so allowed him to transmit his chakra into the bodies and control them remotely as if they were his own. The many animals summoned by the Animal path also had a number of these body piercings, suggesting that Nagato controlled them as well. The Summoning: Demonic Statue of the Outer Path, when used, pierced many chakra receivers through Nagato's back which inturn allowed Nagato to control the statue.
