"Astro Boy" is a science fiction series set in a futuristic world where robots co-exist with humans. Its focus is on the adventures of the titular "Astro Boy" (sometimes called simply "Astro"): a powerful android created by the head of the Ministry of Science, Doctor Tenma (known as Dr. Astor Boynton II in the 1960s English dub; Dr. Boynton in the 1980s English dub). Dr. Tenma created Astro to replace his son Tobio ('Astor' in the 1960s English dub; 'Toby' in the 1980s English dub and the 2009 film), who was killed in a self-driving traffic collision (first ran away, then was killed in the accident in the 2003 anime; vaporized by the Peacekeeper in the 2009 film). Dr. Tenma built and adopted Astro in Tobio's memory and treated Astro as lovingly as if he was the real Tobio. However, Dr. Tenma 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 in the manga, 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 (the Great Cacciatore in the '60 English dub). In the 1980 edition, Hamegg kidnapped Astro while Tenma was trying to find him. In the 2009 film, Tenma rejected Astro part-time because he could not stop thinking about his original son, but later during the film, Tenma realized that Astro made credit to replace Tobio; as a result, Tenma decided that he would readopt Astro. None these events about Astro being rejected (completely or temporarily) or kidnapped in both the 1960 and 1980 cartoons as well as in the 2009 film happened in the 2003 cartoon as Astro's birth was given by Professor Ochanomizu (Dr. Elefun in the 1960 and 1980 cartoons, as well as in the 2009 film; Dr. O'Shay in the 2003 cartoon).
