Astro Boy (アトム Atomu) known in Japan as 'Mighty Atom' or 'Iron Arm Atom' is a fictional character created by Osamu Tezuka. A robotic boy with human emotions created by Umataro Tenma. Tenma created Astro in the image of his deceased son Tobio Tenma. After learning that Astro is robotic and therefore cannot function like a biological human boy, Tenma sells Astro to a robotic circus out of a fit of rage. Astro forced into fighting other robots against his will in the robot circus is eventually rescued by Hiroshi Ochanomizu. Astro fits the embodiment of a hero, he has a strong sense of justice and is always willing to defend those who can't defend themselves. A natural pacifist, he always attempts to solve situations intelligently with diplomacy. He has an extreme care for the preciousness of life much like Tezuka.

Astro initially debuted in the 1951 manga Captain ATOM. His character was received so well by readers that by April of the same year he appeared in his own series, Tetsuwan Atomu, which later got a paperback release in 1975. The series proved such a success that it launched into an international franchise of anime, manga, films and video games. Tezuka, originally designed after traditional Disney characters of the time, Astro's style reflects that of Mickey Mouse. A simple cartoon style of character, although Tezuka would implement some of his own styles into the drawings that would become commonplace for most anime and manga that came after.

Astro became one of the first major manga characters in Japan to successfully adopt widespread merchandise. He has appeared on everything from food items, T-Shirts, mugs, calendars, and stickers. He also became a very successful line of toys and action figures. His success in merchandise continues today especially in items such as Funko's Pop figures.

Since his conception, Astro has become so popular in Japan that he has cemented a status as a cultural icon. Astro's influence as an illustrated character can be compared to others from separate countries such as MIckey Mouse, Popeye, Felix The Cat, Bugs Bunny and TinTin.

Creation and Conception


Tezuka was a lifelong fan of Disney and he styled many of his early characters based on famous Disney characters. Astro would continue this trend of characters designed after Disney characters, using a simplistic cartoon style. Astro bears a strong resemblance to Mickey Mouse Disney's most popular character. The most prominent feature of Astro's design that borrows from Disney is in the head. His head uses a large circular shape, also being used by many popular American animated characters at that time. Psychologically this suggests Astro's innocence, the spikes on his head also suggest an edge to his personality.

Astro Boy's most defining feature are his eyes, especially in the anime series due to the use of limited animation Astro's eyes were designed to be fully reactive to light and feel dynamic this would become a very common design aspect in anime and manga characters that would follow. The use of the eyes in this manner allowed the facial expressions ti use less animation yet seem more real.


Abilities and Powers

Tenma designed Astro to be the most advanced robot in the world. Potentially the most advanced feature included in Astro is his artificial intelligence which accurately simulates real human emotions. Astro was built with super strength, he possesses 100,000 horsepower, which at the time of his creation made him the world's most powerful robot. He also has super speed with two powerful jet engines built into his legs he has the ability to fly past supersonic speeds. He has also shown capabilities of super human intelligence able to solve even the most complex mathematics with the speed of a calculator he can even view objects down to their molecular structure,and even has the ability to translate over 60 different languages.
