Obito Uchiha was a member of Konohagakure's Uchiha clan. He was believed to have died during the Third Shinobi World War, his only surviving legacy being theSharingan he gave to his team-mate, Kakashi Hatake. In truth, Obito was saved from death and trained by Madara Uchiha, but the events of the war left Obito disillusioned with reality, and he inherited Madara's plan to create an ideal world. Resurfacing under the names of Tobi and Madara Uchiha himself, Obito helped Nagato reform Akatsuki from the shadows. Eventually, he went public with them and started the Fourth Shinobi World War. However, towards the war's conclusion, Obito had a change of heart and, as atonement, sacrificed his life to save the same world he sought to replace.
