Astro Boy

Astro Boy was written by Osamu Tezuka. The series start around 1960's, 1980's and finally in 2003. A boy named Tobio died because of an accident and he's the son of Dr Tenma. Dr Tenma then created a robotic boy with his son image. After realized that this invention couldn't replace his son he sold the robot to the circus. Later, the robot saved by Dr Ochanomizu and taken into his care and give him name Astro. Astro become a robot who fight crimes. In 2003, the story nearly the same, only Dr Tenma destroy his lab and erase Astro memory after created him. After that Dr Ochinomizu, the head of the Ministry of Science revived him and gave him normal life as a 6th grade student. I'll say the series is recommended for all ages and I think it's quite good.
