Madara Uchiha is one of the founders of Akatsuki and its current leader, a descendant of the Sage of the Six Paths. Long ago, Madara became the first possessor of the Mangekyo Sharingan, a rare form of the eye condition unique to the Uchiha which gave him the strength to take control of the Uchiha clan, though it rendered him blind from overuse until he took his own brother's eyes in order to regain his sight.Madara eventually banded together with Hashirama Senju to create Konohagakure. The two founders disagreed on who should lead their new village, and after a momentous battle between the two it was believed that Madara had died,though he later revealed it was a ruse to copy Hashirama's powers.
