Dororo (Japanese: どろろ) is a Japanese manga series from the manga creator Osamu Tezuka in the late 1960s. An anime television series based on the manga consists of 26 half-hour episodes that aired in 1969. It was also made into a live-action film in 2007. A 24-episode second anime television series adaptation by MAPPA and Tezuka Productions premiered on January 7, 2019.
During the late 1960s, manga featuring demons was popular among kids. Dororo was first serialized in Weekly Shōnen Sunday between August 27, 1967, and July 22, 1968, before being cancelled. Parallel to the anime broadcast the manga was then concluded in Akita Shoten's Bōken'ō magazine.
Tezuka's childhood memory of his friends pronouncing dorobō (どろぼう, "thief") as dororo inspired the title of this work. In the live action movie series, the name is explained to be a southern term for Hyakkimaru, meaning "Little Monster".
The anime series bears the distinction of being the first entry in what is now known as the World Masterpiece Theaterseries.
