10 best sci-fi anime of all time
1. Outlaw Star (1998)
Gene Starwind and his young partner Jim Hawking are small-time freelancers who end up with an experimental ship they name the Outlaw Star. The show mixes treasure hunting, gunfights and comedy. It came out the same year as Cowboy Bebop and is a lighter companion to it.

2. Trigun (1998)
Vash the Stampede is a gunman with a huge bounty on his head who refuses to kill anyone. On a desert planet, he is followed by two insurance agents trying to limit the damage he causes. The series was rebooted as Trigun Stampede in 2023, and its continuation, Trigun Stargaze, was scheduled to premiere in January 2026.
3. Cowboy Bebop (1998)
Spike Spiegel and the crew of the Bebop hunt bounties across the solar system in 2071. Shinichiro Watanabe’s series is famous for Yoko Kanno’s jazz soundtrack and episodes that move from comedy to noir. Netflix’s 2021 live-action version was cancelled after one season, and the original remains the one to watch.
4. Dr. Stone (2019)
A mysterious flash turns every human into stone. Thousands of years later, teenage genius Senku Ishigami wakes up and decides to rebuild civilisation using science, starting from scratch. The final season, Dr. Stone: Science Future, airs in three parts, with the third part announced for April 2026.
5. The Promised Neverland (2019)
Emma, Norman and Ray live in a happy orphanage until they discover what the place really is. The first season is a tense escape thriller and one of the best single seasons of anime. The second season, which skipped much of the manga, was poorly received by fans.
6. Space Brothers (2012)
Brothers Mutta and Hibito Nanba promised each other as kids that they would go to space. Hibito becomes an astronaut, while Mutta, older and recently fired, decides to try again. It is a warm, slow-burning story about chasing a childhood dream in your thirties.
7. Planetes (2003)
In 2075, Hachimaki and his crew collect space debris, the junk floating in orbit that can destroy ships and satellites. Planetes is the most realistic show on this list, and its focus on orbital debris looks more relevant every year.
8. Mobile Suit Gundam (1979)
The original Gundam changed the giant robot genre by treating its mecha as weapons in a messy war with real casualties on both sides. Almost every anime fan has seen at least one Gundam series. The franchise is still active: Mobile Suit Gundam GQuuuuuuX aired in 2025.
9. Space Dandy (2014)
Dandy is a self-styled cool alien hunter who is not very good at his job. Each episode is a standalone adventure, often with a different style, from musicals to zombie stories. With Cowboy Bebop’s Shinichiro Watanabe as chief director, it is the funniest pick here.
10. Psycho-Pass (2012)
In a future Japan, the Sibyl System scans citizens’ minds and measures their likelihood of committing a crime. Rookie inspector Akane Tsunemori starts to question the system she enforces. Written by Gen Urobuchi, it is one of the sharpest dystopian stories in anime. The film Psycho-Pass Providence released in 2023.
