Astro Boy is the protagonist of the manga of the same name. He starred in the 55th episode of Death Battle, Mega Man VS Astro Boy, where he fought Capcom's Mega Man.


In the futuristic year of 2003, Astro Boy (dubbed the Mighty Atom in Japan) was created by Dr. Tenma to replace his son Tobio, who was killed in a car crash, in order to have a second chance of being a father. However, Dr. Tenma realized that Astro Boy would not truly replace his son, so he sold him to a robot circus. During this time Astro Boy was discovered and adopted by Doctor Ochanomizu, who would teach Astro Boy and help him save the world on multiple occasions.
