Metropolis , also known as Osamu Tezuka's Metropolis or Robotic Angel, is a Japanese manga by Osamu Tezuka published in 1949. It has been adapted into a feature-length anime, released in 2001. It has some parallels to the 1927 film of the same name, though Tezuka stated that he had only seen a single still image of the film in a magazine at the time of creating his manga.

Osamu Tezuka was a Japanese manga artist, cartoonist and animator. Born in Osaka Prefecture, his prolific output, pioneering techniques and innovative redefinitions of genres earned him such titles as "the Father of Manga" , "the Godfather of Manga" and "the God of Manga" . Additionally, he is often considered the Japanese equivalent to Walt Disney, who served as a major inspiration during Tezuka's formative years. Though this phrase praises the quality of his early manga works for children and animations, it also blurs the significant influence of his later, more literary, gekiga works.
