Astro Boy is a robotic child with exceptional abilities and a sophisticated AI system. He was created by Dr. Tenma, who designed him to replace his deceased son Tovio. Dr. Tenma later destroyed his laboratory and shut down Astro, but Dr. O'Shay revived him and tried to give him a normal life as a 6th grade student. Astro assists the police in their mission to prevent rogue robots and bigoted individuals from causing harm, while he also faces prejudice for being a robot and seeks the truth about his creator.
