Astro Boy has been adapted into three anime series produced respectively by Mushi Production and Tezuka Productions, with a fourth series in development. The manga was originally produced for TV as Astro Boy, the first popular animated Japanese television series that embodied the aesthetic that later became familiar worldwide as anime. After enjoying success abroad, Astro Boy was remade in the 1980s as New Mighty Atom, known as Astroboy in other countries, and again in 2003. In November 2007, he was named Japan's envoy for overseas safety. An American computer-animated film based on the original manga series by Tezuka was released on October 23, 2009. In March 2015, a trailer was released announcing a new animated series. The success of the manga and anime series led it to becoming a major media franchise consisting of films including a major motion picture, a number of soundtracks and a library of Video Games. The series was also among the first to embrace mass merchandise including action figures, collectible figurines, food products, clothing, stamps and trading cards. The franchise has earned 3 billion dollars making it one of the highest grossing anime media franchises.
Astro Boy has become one of the most successful manga and anime franchises in the world. The combined 23 tankōbon volumes have sold over 100 million copies worldwide making it the tenth best-selling manga series of all time. The 1963 anime series was an astounding success it became a mainstream hit on television in both Japan and the United States. Astro Boy has been praised for its importance in developing the anime and manga industry. It has been featured on numerous greatest anime of all time lists and has partially inspired other authors in the creation of influential manga.
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 (aka Dr. Astor Boyton II in the 1960 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 died in a self-driving car accident (first ran away, then died as he fell off a building 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 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 Toby; as a result, Tenma decided that he would readopt Astro.
After some time, Professor Ochanomizu, the new head of the Ministry of Science (co-head of the Ministry of Science in the 2009 film), notices Astro Boy performing in the circus and convinces Hamegg to turn Astro over to him. (In a retcon the story becomes far more violent and complicated). He then takes Astro in as his own and treats him gently and warmly, becoming his legal guardian. He soon realizes that Astro has superior powers and skills, as well as the ability to experience human emotions.
