Head of State (Earth-2356)

Head of State is a title used to refer to the leader of a planet, corporation, or government. As leader of the Outer Rim planet Ame and the Confederacy of Independent Systems, Nagato possessed the title. As Pain, he determined the overall strategy for the confederacy military, served the leader of the Akatsuki and presided power over the Separatist Council, albeit never personally and never revealing his appearance outside of the Akatsuki members to keep Ame's government a secret.
