Sekaikage

The Sekaikage (堺影, World Shadow) is a term used by Sasuke Uchiha to describe his role if he were to take over the ninja system. To obtain this position, Sasuke planned to drive the world into revolution, resulting in a Fifth Shinobi World War that would cause all the current ninja systems in all five of the main villages to collapse. As the people would begin to rebuild, Sasuke would emerge as the strongest human being and become the leader of the world in light of the death of Naruto Uzumaki. All subsequent Sekaikage would be descendants of Sasuke through an unspecified spouse. None of these plans ended up coming to fruition, however, as Naruto would defeat and redeem Sasuke shortly after Sasuke created these plans.
