Background: Madara Uchiha is the founder and benefactor of the high caliber criminal organization, Akatsuki. He is the first to use the revered technique among Uchiha clan, the Mangekyo Sharingan. He is once a great man of virtue but greediness got the best of him.
The Deal with him: As the founder, his ultimate goal is to gain the enormous power of the tailed beasts and further strengthen his Eternal Mangekyo Sharingan. He has calm disposition and a cunning villainous personality.
He appears before the group as Tobi and becomes Deidara's partner. In this disguise, he portrays a carefree almost childish personality. He wears a swirling mask with a left eyehole.
Though Pain acts as the leader, his decisions are still based on Madara's opinions. Madara is not at all impressed with Pain and often picks on him. Either he's secretly insecure with Pain or he just loves power tripping.
