Honorable Mentions
Before we reveal the number one sci-fi series every anime fan must watch, here are some honorable mentions.
Outlaw Star (1998)
MyAnimeList Score: 7.8 / 10
Studio: Sunrise
Another fantastic Studio Sunrise space adventure series that is often overlooked when talking about anime classics.
Girls’ Last Tour (2017)
MyAnimeList Score: 8.2 / 10
Studio: White Fox
A wonderful slice-of-life sci-fi series that follows two girls that do whatever they can to survive after a brutal war left them as the sole survivors of their country.
A Certain Scientific Railgun (2009 – 2020)
MyAnimeList Score: 8.2 / 10
Studio: J.C. Staff
One of the longest-running sci-fi series of all-time, very few series can immerse you in a huge world as the Certain series can.
*Note: This is a trailer from the series’ most recent season. The series is a spin-off of the original A Certain Magical Index. However, Railgun is highly favored over Index. If you need the watch order, you can use this very helpful video here as a guide.
FLCL (Fooly Cooly) (2000)
MyAnimeList Score: 8.0 / 10
Studio: Production I.G
A relatively short sci-fi series that every anime must-watch down the line. I guarantee it is unlike any other series you’ve seen and it’s an absolute blast to watch.
Now it’s time to reveal the number one sci-fi series every anime fan must watch. Although the show just recently finished, I believe it was a big sci-fi hit and that it deserves the spot. Hopefully, you’re new to a lot of these series on this list and will watch them in the near future. And if you’ve watched any, or all, of the series listed, definitely leave your comments at the very end of the article!
