Madara Uchiha ehk Tobi

(うちは　マダラ, Uchiha Madara?) is the founder of Akatsuki and the first possessor of the Mangekyo Sharingan, a rare form of the eye condition unique to the Uchiha.

Though it gave him the strength needed to take control of the Uchiha clan, overuse of the Mangekyo Sharingan left him blind, and it was only by taking his own brother's eyes that he was able to regain his sight.

Madara eventually banded together with Hashirama Senju (First Hokage) to create Konohagakure.
The two founders disagreed on how to run their new village, and after a momentous battle between the two Madara was expelled from Konoha.

In later years Madara sent the Nine-Tailed Demon Fox to attack Konoha, though the fox was sealed away by Minato Namikaze (Fourth Hokage).

Beaten once again, Madara infiltrated Konoha in secret, trained Itachi Uchiha, and subsequently assisted him in massacring the Uchiha clan.
