In the 50’s and 60’s Osamu Tezuka (who also made Black Jack) was making Astroboy.
Astroboy is known as Tetsuwan Atom/鉄腕アトム in Japan.
The animation series it started is thought to be one of the origins of Japanese animation as we know it today.
Astroboy is set in the future and Astroboy is a robot created by a scientist to take the place of his son.
He was rejected by his father – of course, you can never replace a lost loved one.
However, Astroboy ended up showing superior characteristics for a robot and fights crime and injustice.
It was made into an animation and even an American CGI film.
