Astro's parents

Background
Astro has a dad, the famous scientist Dr. Tenma. Dr. Tenma created him to replace his son Toby. However, Dr. Tenma saw that Astro couldn't ever be Toby, so he abandoned him to a robot circus. Professor Ochanomizu adopted him then made him robot parents.

As Professor Ochanomizu described his creations, his father was a strong man, and Astro had a beautiful mother.

In the 1980 version of Astro Boy, these parents were abducted by the power hungry Atlas, in an attempt to force Astro to help him in his plot to overthrow the humans.
