Astro Boy is android boy fashioned after Tobio Tenma (Tenma Tobio; "Toby Boyton" aka Astor Boynton III), he possesses the strength of 100,000 horsepower (later
1,000,000) and the heart of gold. He has seven amazing powers: flight, multiple languages, analytical skills, headlight eyes, strength, hidden weapons in his back and the ability to tell what's right and wrong. In addition he has a built-in geiger counter and radio system plus hypersensitive hearing. He was in a car accident and died. But later, he was brought back to life by his father Dr. Tenma and Dr. Elefun. Now his new name is Astro. His father, Dr. Tenma, thought that Astro is just like Tobio. But instead he thought he created a monster. So instead he yells at him saying "you are not my son!" Hurt and all alone, Astro meets a ringmaster. He thought that the ring master was nice. But he was wrong. Poor Astro was kidnapped!! He yelled for his father, but he never showed up to rescue him.

Astro Boy was created by Doctor Tenma, and was meant to be a replacement for his deceased son named Toby (Tobiō in Japan). However, because Astro was not able to grow and age like a normal human child, Doctor Tenma abandoned him to a Robot Circus led by the cruel Ham Egg. At the circus, Astro Boy was found by Professor Ochanomizu and adopted. Professor Ochanomizu gave Astro a family with a robotic mother, father, sister (Uran) and brother (Cobalt). As head of the Ministry of Science, Professor Ochanomizu often calls on Astro to help resolve situations involving humans, robots and (on occasion) extraterrestrials.

Astro Boy has several capabilities to aid him in his adventures:

  • The ability to translate more than 60 languages
  • Strength equivalent to 100,000 horsepower (75 MW)
  • The ability to fly using jets in his legs and arms
  • Amplification of his hearing up to one thousand times

  • Guns deployed from his posterior
  • An electro-heart that can discern people's criminal intentions
  • Bright eye-lamps to assist his vision
  • Laser guns in his finger tips
  • Laser cannons in his arms
  • An extremely accurate electronic brain

Despite his abilities and work for good, Astro is often ostracized by the human race for being a robot. Since he is not officially considered a citizen, he often has to deal with the prejudice of humans against robots. Ultimately, Astro has to find a way to bring peace between humans and robots
