Astro Boy (Tetsuwan Atomu"Mighty Atom") Astro Boy is a science fiction series set in a futuristic world wherein androids co-exist with humans. Its focus is on the adventures of the titular "Astro Boy" (sometimes called simply "Astro"), a powerful robot created by the head of the Ministry of Science, Doctor Tenma, to replace his son Tobio, who died in a car accident. Dr. Tenma built Astro in Tobio's image and treated him as lovingly as if he were the real Tobio, but soon realized that the little android could not fill the void of his lost son, especially given that Astro could not grow older or express human aesthetics (in one set of panels, Astro is shown preferring the mechanical shapes of cubes over the organic shapes of flowers). In the original 1960 edition, Tenma rejected Astro and sold him to a cruel circus owner, Hamegg. (C) by Osamu Tezuka, who is often reputed as the "god of manga."
