Astro is feeling extremely lonely. He wants a family of his own and Dr Elefun agrees to help. While the robot factory is building Astro's parents, an unfinished robot named Colosso is activated prematurely. When Colosso meets a gang of thieves, they enlist him to commit their crimes. Aware only that a robot is responsible, Inspector Gumshoe blames Astro for the crime wave.
**Special Note: in the original Japanese version, Colosso was named "Frankenstein"
Astroboy fights Colosso, who's not all bad, just not all there.
