In the future, humanity has created robots that have feelings and are able to make decisions of their own; they have a soul. Mankind has become afraid of the dangers these new machines possess, specifically the super powered Astro Boy. Thankfully, Astro is kind and gentle and will only use his powers to defend the humans and protect them.

The anime follows Astro from his 'birth' up until the final episodes. There have been numerous mangas, animes, and other content on Astro Boy. This is the 2003 English version seen on Kids WB and Cartoon Network. 

Each episode usually has Astro learning a few new things along with protecting humanity from destruction either by cataclysmic events or robots who have gone berserk. Most of this is caused by the evil Dr. Tenma who actually created Astro but has come to hate the human race. 

Astro Boy is a classic and you should definitely check out a volume or two. Once you start watching one, you'll want to watch them all. You might notice some similarities between Astro and Mega Man, a video game robot designed by Keiji Inafune. Part of the fun for myself is pointing out all the similarities, which are numerous. If you're a fan of one then you'll definitely be a fan of the other.

Astro Boy is a more like a cartoon show than an anime but that shouldn't stop you. Whether adult or kid, you'll fall in love with all the characters. It's good, wholesome fun and not something you should miss.
