At the Ministry of Science, fervent Professor Ochanomizu alongside his coworkers strive to reactivate Atom—the first robot with a human heart. Atom is the masterpiece of enigmatic Professor Umatarou Tenma, who built the android to replace his deceased son Tobio. However, while Tenma inexplicably shut down his brainchild and disappeared, Ochanomizu refuses to let such a major breakthrough in science go to waste.

Despite having the appearance of a nine-year-old, Atom not only possesses incredible strength and intelligence, but he is also endowed with a remarkable conscience and compassion that rivals humans. Sadly, the mechanical boy soon faces rejection and learns that not everyone is as welcoming as Ochanomizu. Although automatons have integrated into society, they are accepted only as tools and even seen as an upcoming threat to mankind's dominion.

Dreaming of a world where people and robots can prosper together, Atom dedicates his existence to protecting the lives of both and inspiring them to form genuine bonds.

Astro Boy: Tetsuwan Atom was produced to celebrate Atom's birthday—on April 7, 2003—as well as the 40th anniversary of the original series. While it keeps Osamu Tezuka's art style, the remake features modernized animation and various new Western characters. The anime aired on Fuji TV in Japan; overseas, it was broadcasted on Animax and on local televisions such as Kids WB in North America and YTV in Canada. The series won the 2004 Tokyo Anime Award in the Television Category.

In Japan, 13 DVD volumes were released between October 3, 2003 and October 1, 2004. In addition, four limited-edition DVD boxes were made available from December 5, 2003 to October 8, 2004. The boxes included: three discs, three postcards, an action figure, and a 16-page booklet. The first box exclusively contained three additional trading cards. In North America, Sony Pictures Home Entertainment released a complete series DVD collection in 2005 and five single discs in 2009; Mill Creek Entertainment produced a complete series collection in 2015. Four episodes of the anime were included in the Pop Culture Bento Box DVD set released by Mill Creek Entertainment in 2019.

The series was adapted into two video games produced by Sega titled Astro Boy: Omega Factor and Astro Boy. The former became available on August 17, 2004 for the Game Boy Advance while the latter was released for the PlayStation 2 in 2004 in Japan and North America and in 2005 in Europe. Additionally, a clip named ROBOT - Yume no Astro Boy e, which presents actual robot technology with the digital animation of Atom, was screened at different science museums in Japan starting on April 15, 2004.

I watched this as a ten year old boy and have great memories of waking up at 5:30am to watch it. I was the only person I knew who'd watched it but it felt like my own secret show. Anyway, I picked up Pluto the manga and have almost finished it, and the memories came flooding back. From what I remember it was great, then again I was 10. If you know any 10 year old's i'm sure they'd love to watch it. Probably best to go with a manga like Pluto if you're older, as this show probably won't appeal to adults.

This anime is really one of my favourites, which can seem odd, especially if I add that I was 19 when I watched it.
I am really pained when I see people saying that it is a show enjoyable only by kids. It tackles so crucial themes with such an ease and a simplicity that it is able to touch deeply anyone, kids and adults alike. There are of course goofy moments proving that this show was mainly meant for kids. The moral of the show, however, is so righteous (in my opinion) that it would be a shame if only kids were to enjoy ...

I used to remember seeing an episode of this back when it was on Cartoon Network fifteen years ago. Never really known too much about the character back then, but it was one of the first animes I had the courtesy to watch. The story is simple to follow, despite a few filler episodes here and there. It's lighthearted but also dark to a certain degree. The animation looks pretty good and even beautiful at times and the sound design is top notch. I enjoy listening to the shows soundtrack so much, I might just buy the soundtrack for it if it's even a thing. ...
