PEIN

Pain's six bodies
Pain (, is the leader of Akatsuki and the partner of Konan. "Pain" is not a single person, instead being six entirely different bodies that share the same mind. The only common physical characteristics amongst them are their orange hair color, a number of body piercings, and the Rinnegan (, Rinnegan lit. "Samsara Eye"). The Rinnegan, a unique eye condition characterized by a number of concentric circles around the pupil, allows the wielder to utilize any ninja ability. Pain uses it to share visual information amongst all six bodies, giving them the ability to coordinate offense and defense as if they were a single entity. Each body possesses a unique skill; the body with a large ponytail, for example, can summon a wide array of creatures, while the fat body is able to absorb attacks as a form of defense. The six bodies' combined might was enough to singlehandedly overthrow Amegakure's former governmental body, giving Pain control of the village and god-like status amongst the villagers in the process.
When first meeting Pain, Jiraiya assumes the entity to have once been Nagato , Nagatoan Amegakure orphan he trained in the past. Though Nagato was the first possessor of the Rinnegan that he encountered and Pain refers to him as sensei, Jiraiya begins to doubt this initial assumption when he sees Pain's six bodies. Realizing that all six bodies once belonged to ninja he encountered when he wandered the Naruto world, Nagato's body not being among them, Jiraiya risks his life to learn the secret of Pain. He succeeds and is able to send his, as yet undisclosed, discovery to Konohagakure, though is killed in the process..
