Adopting the identity of the spiral-patterned Zetsu which served as his bodysuit during his recuperation, Tobi, Obito poses as the carefree flunky and becomes Sasori's replacement and Deidara's partner early in Part II. After Itachi's death, Obito takes a special interest in Sasuke Uchiha and takes him under his wing by revealing the truth about their clan's massacre. He presents himself as Madara after Nagato's death, revealing the "Eye of the Moon" Plan to the Kage and explaining his intention to become the Ten-Tails Jinchuriki to bring all life within an Infinite Tsukuyomi. After the Kage refuses to surrender to him, Obito declares the Fourth Great Ninja War and forms a reluctant alliance with Kabuto Yakushi, who blackmails him with the real Madara's body. Obito goes to retrieve Nagato Uzumaki's from his body. In the process, he is opposed by Konan. Their argument, in which Konan affirms her faith in Naruto, and Obito (still impersonating Madara) claims his original ownership of the Rinnegan, quickly evolves into a fight. Konan attempts to catch him in various large-scale paper bomb detonations, but he manages to trick her with the Izanagi technique, and stabs her in the back; he obtains the location of Nagato's body through genjutsu, and proceeds to choke her to death. He retrieves Nagato's body and Rinnegan successfully.
