Obito Uchiha (Japanese: うちは オビト, Hepburn: Uchiha Obito), also known by his alias Tobi (トビ), is a character in Masashi Kishimoto's manga Naruto. He is first introduced in a Kakashi Chronicle sidestory as a child soldier who sacrifices himself to save his friends (Kakashi Hatake and Rin Nohara, led by Minato Namikaze) from a rival group of ninjas. Although he was believed to have died, Obito is later revealed as the real leader of the terrorist organization, Akatsuki, mainly acting behind the scenes for a majority of the group's tenure. He uses the alias of his superior, Madara Uchiha, and conceals his true identity with masks as one of the primary antagonists in the series' second half. Obito and his varied personas have appeared in Naruto video games and animated adaptations.
