Naruto (manga)
Nagato, called Pain.  He had Madara's eyes put in him when he was a child. He is the Akatsuki's leader and partner of Konan.  Nagato uses the dead body of his dead friend Yahiko in the Deva Path to be the "Pain."  Yahiko had helped start the Akatsuki with Nagato and Konan.  They learned ninjutsu from Jiraiya. Nagato was hurt after Yahiko's died. Then, he used six bodies known as the Six Paths of Pain. Each body used a sixth of his power. After he killed Jiraiya, Nagato led an attack on the Hidden Leaf. Naruto beat his Paths and restored Nagato's faith in Jiraiya's teachings.  Tobi later stole the Rinnegan from Nagato's resting place.  Madara took it back later. Kabuto brought Nagato back to life in the Fourth Great Ninja War. Then he was sealed by Itachi.
