Pain

Pain acts as the leader of Akatsuki and the partner of Konan, though he and Konan secretly report to Tobi, appearing in the form of six entirely different bodies that share the same mind, referred to as "The Six Paths of Pain". The only common physical characteristics amongst them are their orange hair color, a number of body piercings, and the Rinnegan ("Samsara Eye").
The Rinnegan, a unique eye technique (dojutsu) 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. Following the capture of one of the six bodies by Jiraiya, a new body appears to replace it. Pain's might was enough to overthrow Amegakure's former governmental body, giving Pain control of the village and god-like status amongst its citizens. He use “Rei” (Zero) ring on his right thumb.
