Before there was My Hero Academia, Attack on Titan, Dragon Ball Z and even Pokémon, there was Astro Boy.


Widely regarded as the first popular Japanese animation that embodied the aesthetic that would go on to be coined as 'anime' all over the world, the original manga, written by Osamu Tezuka, appeared in 1952 and ran until 1968, soon becoming a national - then global - sensation.

There have been a plethora of anime series based on Tezuka's original manga, first in 1959, then famously the 1963 titular series, followed by a number of additional series thereon - including the 2003 reboot, which is likely most familiar to millennials and Gen-Zers.

Astro Boy stands as one of the most successful manga and anime of all time, having sold over 100 million copies, the 1963 anime series becoming acclaimed in not just Japan but also the USA.

In fact, there are so many facts about Astro Boy's success, this whole article could be dedicated to them.

So it's no surprise that Pluto, a spin-off of Astro Boy created by Naoki Urasawa and Takashi Nagasaki, long-time fans of the original robotic boy adventures, has finally been picked up for an anime adaptation - and by Netflix, no less.

While it's noticeably darker than the original Astro Boy stories, it's nonetheless a faithful extension of the universe that fans will love diving into.

Read on to learn everything we know about Pluto, including a release date, trailer and cast announcements.

What is the plot of Pluto?

Pluto is specifically based on the The Greatest Robot on Earth arc from 1964's Astro Boy, and takes place in a neo-futuristic world where humans and high-functioning robots are able to co-exist.

However, after the world's seven most advanced robots and their human allies are slain in cold blood, it's down to Inspector Geischt to uncover the conspiracy that's afoot - all the while being a target himself.

Co-author Nagasaki spoke about how he and co-creator Urasawa incorporated the original messages of Astro Boy into Pluto: "PLUTO inherits the philosophy of Tezuka and does not only merely convey a message of anti-war, but reminds us that there is suffering on both sides... but still, the only remaining answer is peace."
