Uchiha Madara

  Madara Uchiha  is one of the co-founders of the Hidden Leaf Village along with Hashirama Senj.Though he was a childhood friend of Hashirama during the endless conflict, their friendship ends as a result of the war. As the leader of the Uchiha clan, Madara's overuse of Mangekyo Sharingan blinds him, forcing him to take the eyes of his late younger brother Izuna. This allows Madara to use his newly awakened Eternal Mangekyo Sharingan to continue the ongoing war between the Uchiha and the Senju.
