Tobi (Madara Uchiha) (Not a Member)

Tobi was initially seen as an associate of Zetsu. He appeared clumsy and was very polite in his speech. After Sasori was killed in battle, Tobi was eager to replace Sasori as a new member of Akatsuki. He eventually succeeded and took over Sasori's position in the group. He was then partnered with Deidara. After Deidara's death, it was revealed Tobi gave direction to Pain as leader. He was also revealed to possess the Sharingan and claimed to be Uchiha Madara. When Tobi revealed his true nature to Kisame, the man recognized him both as Madara and as his village's Mizukage. The full nature of Tobi and Madara's full identity is unknown.
