Who is madara Uchiha?

Answer 1

Madara Uchiha is one of the founders of Akatsuki and its current leader. 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.In later years, the Nine-Tailed Demon Fox attacked Konoha, an act Minato Namikaze and others said to have been Madara's doing, though he denies it. Once the fox was sealed by Minato, Madara infiltrated Konoha in secret, and subsequently assisted Itachi Uchiha in assassinating the Uchiha clan. Kisame Hoshigaki, upon seeing his face, recognizes him as a former Mizukage.

Much of Madara's role in the series has been under the guise of Tobi , who replaces Sasori in Akatsuki after Sasori's death. While acting as Tobi he is carefree and goofy as opposed to Madara's usual serious self. Tobi's tendency to take credit for other's work and undermine his superiors annoys his partner, Deidara, who either blows up or strangles him in comical fashion as punishment. After Deidara dies during a battle with Sasuke, the Tobi persona is discarded as Madara takes a special interest in Sasuke's development. However, Madara has not completely outlived the use of his guise as he reassumes Tobi's personality on occasion, such as to delay a group of Konohagakure ninja.

Though Madara's face as it appeared during Konoha's founding has been shown in full at various points in the series, he always wears a mask in the current Naruto storyline. The mask features a swirl pattern focused around his right eye. His black hair (cut back from his earlier years) is the only constantly visible part of his face. When asked how Madara could have survived since Konoha's founding generations ago, Itachi Uchiha states that Madara is immortal. The specifics of his immortality have yet to be touched upon, though Madara implies the potency of his chakra has something to do with it. In battle he has been shown capable of making his body intangible, leaving him visible but otherwise impervious to most forms of damage. He can also teleport over great distances at will.

Answer 2

Madara Uchiha is the Leader of the Uchiha clan [which is said to be immortal].

He is also the Co-founder of Konoha.

When he was young he and his brother used to compete all the time.

They were the first in the clan to awaken their Mangekyo Sharingan.

However Madara Uchiha overused his Mangekyo Sharingan, resulting in him being blind.

Every Uchiha tried to heal him but nothing worked.

Madara claims that his brother willingly gave his eyes to him, but Itachi denies this. So Madara took his brothers eyes to restore his eyesight and gained an Eternal Mangekyo Sharingan[which also said to be making him immortal].

He is the founder of Akatsuki and also goes in as Tobi.
