Cast out when he cannot meet the grieving father’s expectations, Astro Boy is dealt a cruel double blow – he is also crushed to learn he is a robot, not even a human being.

As Dr. Tenma, the man who created him, removes his energy source, Astro Boy forgives him for what he is doing.

In the climactic battle, the strands of the story come together as Astro Boy accepts his mixed human-robot nature and finds his destiny as mankind’s savior. (official distributor synopsis)
