Table of contents

Like any form of visual media, there are countless genres and sub-genres of anime shows and films. With no limits to the amount of creativity a writer can have when creating an animated piece of work, anime has been able to cover a wide variety of topics, themes, and cultures. One of the most popular genres is science fiction anime, with a few of the highest-rated movies and series being categorized as sci-fi.

Those looking for adventures that explore the far reaches of space or ask the big what-if questions of life in the future will find that Japanese animation has them covered. What are the best sci-fi anime ever?

Each anime's MyAnimeList score is included as a reference; however, it is not the ranking's only determining factor since things like genre influence will also be taken into account. Some shows also blend sci-fi with other genres, with the former taking a backseat at times.

Best Winter 2024 Sci-Fi Anime

Winter 2024 has been fantastic so far, arguably exceeding expectations. While not introducing as many huge names as Fall 2023, the current quarter is jam-packed with good series that are just a joy to watch. Solo Leveling is the season's biggest show, and the manhwa adaptation has generally lived up to expectations. Although leaning into fantasy territory, the anime feels separate from the genre's many Winter 2024 stories due to its modern setting. In general, action is well-covered thanks to Blue Exorcist, Ishura, Sengoku Youko, High Card, Undead Unluck, Shangri-La Frontier​​​​​​, and Kingdom.

As always, sci-fi is not omnipresent in Winter 2024; however, the selection is wider than most recent seasons. Synduality: Noir Part 2 is paying off the previous cour's decent work, while Brave Bang Bravern! is a fun and weird Mecha project. What are the season's best sci-fi anime​​​​​​?

Winter 2024 Anime Lineup: Where To Watch Every Series
The Winter 2024 anime lineup is split across Crunchyroll, HIDIVE, Hulu, Netflix, and more. Here is where every show will be airing.

Studio
E&H Production, Sola Entertainment

Max , Adult Swim

A late arrival to the party, Ninja Kamui is shaping up to be among Winter 2024's better shows. The story follows a ninja, Joe Logan, who sets out to massacre his former clan after they kill his family. While that premise might be the definition of basic, the series makes up for it with some intriguing world-building and a lot of visceral action. Due to being associated with Max and Adult Swim, Ninja Kamui appears to have fewer restrictions than most other anime, paving the way for gory fight sequences that don't seem to hold anything back. Now, blood is hardly a shortcut to success, and a series would not be worth recommending if it did not have anything else to offer. Fortunately, Ninja Kamui has consistently high production value along with an engaging story that seems to have more depth than might initially appear to be the case.

Although not as aggressively "sci-fi" as some other properties, Ninja Kamui fits the genre nevertheless. The series appears to take place in the near future, presenting a version of Earth that has more advanced AI and cybernetics. Over-the-top as the show might be, its technology is not that far removed from reality.

Crunchyroll

Created as a Bones celebration, Metallic Rouge has the production value to back that up, along with a story that can feel directionless. Launching with a great first episode that concluded with a pretty fun fight, since then, the anime has been somewhat frustrating with moments of brilliance. Set in a world where artificial intelligence has advanced enough to create humanoids, the central story follows Rouge and Naomi as they seek the Immortal Nine, androids they must kill.

As far as premises go, this is pretty simple, which is not a bad thing; however, Metallic Rouge is shockingly convoluted, to the point of diminishing returns. Each episode seems to introduce new characters and ideas without fleshing either of them out, and things seem to just happen. All that being said, the anime might still bring everything together, and most episodes have enough positives to be worth watching. The series has just not been able to create a cohesive experience yet.

A sci-fi comedy classic, Urusei Yatsura is a sitcom about a perverted guy who winds up with an alien fiancée. Lum loves her darling with all her might, while Ataru mainly wants to flirt with girls and do his own thing, two acts that normally result in a quick electrocution. Urusei Yatsura is a sitcom that resets at the end of most episodes. The anime has a well-established status quo that paves the way to plenty of laugh-out-loud moments courtesy of its larger-than-life protagonists and a plethora of quirky secondary characters.

Sci-fi is associated with heavy social themes and lofty concepts, but the genre can get silly as well. Urusei Yatsura represents that side of the equation, and there is a reason the property has been around since the late '70s.

Now, here are the best sci-fi anime of all time...

This horror anime will make viewers' skin crawl. Following a group of orphaned children being cared for by their appointed Mother, this series shows the traumatic experiences of intelligent kids trying to escape the deadly home they're trapped in.

The Promised Neverland's soundtrack is chilling, the characters are wonderful, and the villains are too creepy to handle. The first episode alone will get audiences hooked. For anime fans looking to get scared out of their pants, this spooky sci-fi anime's first season needs to be a priority. Unfortunately, the second season is underwhelming and rushed, to the point that skipping it might be the better option.

Heavenly Delusion is drenched in mystery. The anime envisions a post-disaster world filled with monstrosities and the scattered remains of human civilization. Maru and Kiruko travel across Japan in search of a place called "Heaven," a journey defined by frustration, near-death experiences, and constant terror. As this unfolds, the anime also follows a group of children living within a research facility that seems to be a safe haven but is likely anything but.

Heavenly Delusion Season 1 Review
Beautiful visuals, mysteries galore, and fantastic characters make Heavenly Delusion one of the most enjoyable shows of the year.

Production I.G's anime has only started to pull back the curtain on the manga's lore and mysteries, allowing viewers to immerse themselves in widespread uncertainty alongside the main characters. So far, Heavenly Delusion has raised way more questions than answers, and if the latter eventually arrive via a sequel, this sci-fi anime could turn out to be one of the greats.

Made in Abyss ranks low because it is more fantasy than science fiction, however, the anime sprinkles just enough elements from the latter to qualify. In this world, adventurers turn to The Abyss in search of glory, descending its numerous layers filled with wonder and horror. The young Riko yearns to follow her mother to the bottom of the Abyss, a seemingly impossible journey that becomes only improbable once the girl befriends Reg, a boy with a body seemingly modified by science.

Young kids going on a wild adventure might sound like a pleasant time, and while Made in Abyss is certainly fantastic, the show is anything but lighthearted. The anime deals with abuse, sacrifice, and human experimentation, just to name a couple of themes.

Academy City is home to espers, people who possess special powers that can range from incredibly potent to harmlessly mundane. As its name suggests, this city houses various schools that seek to teach their students how to control and maximize their abilities; unsurprisingly, there are also plenty of people who want to take advantage of these same children.

A spin-off of A Certain Magical Index, A Certain Scientific Railgun pushes Mikoto Misaka to the forefront, a teenager deeply embedded into Academy City's public guide and underground experimentation. Although the powers are just straight-up fantasy, this anime tackles classic sci-fi themes such as cloning really well. While the first season is pretty forgettable, A Certain Scientific Railgun S and T are both considerably better, delivering compelling character-driven drama along with intense action and even the occasional laugh. The Sisters arc is comfortably among the best sagas in the sci-fi anime genre.

Shonen has hundreds of power fantasies, but very few stories harness the power of science. Set thousands of years after humanity was suddenly frozen, Dr. Stone follows the revived Senku as he tries to use his scientific knowledge to survive in a world that has reverted to the Stone Age. More importantly, he wants to return humanity to its technological heights, a goal that not everyone agrees with.

Dr. Stone's Senku is a brilliant scientist, but he is not infallible or psychic.

Starting strong and improving with each new cour, Dr. Stone manages to juggle drama, humor, action, and even a hint of education. While the premise is outlandish and leans heavily into fantasy, Senku's science is grounded in reality, with the "fiction" part largely stemming from the protagonist's near-unlimited knowledge and the speed at which scientific breakthroughs are achieved.

This exciting space anime is widely loved for its quirky, funky vibes, lovable characters, and fantastic animation. The amount of detail that went into Space Dandy's story and lore is enough to keep viewers glued to the TV until they've binged it all.

The series follows the eccentric Dandy, a space explorer on the hunt to discover new alien species with his energetic team of sidekicks. It's the perfect anime to put on for a good time with plenty of laughs. Along with all the comedy and parody aspects of the show, there are beautiful animation styles, charming dialogue, and amazing storylines.

This fan-favorite sci-fi space western came out over 20 years ago but still continues to hold a big place in the hearts of classic anime lovers. The story follows the fun-loving crew on the Outlaw Star, a ship led by Gene Starwind, on their hunt for the legendary treasure called "Galactic Leyline."

Outlaw Star has a unique animation style and beautifully balances the drama, comedy, and mystery elements. Although its age shines through at times, the '90s series is still charming in its own right, and it has a pulp fiction-esque quality that adds an element of timelessness. While generally overshadowed by Cowboy Bebop, Outlaw Star is nevertheless a fun ride.

Based on CD Projekt Red's Cyberpunk 2077, Cyberpunk: Edgerunners was Trigger's best anime since Kill la Kill, and an argument could be made that the series represents the studio at its absolute peak. Right out of the gate, the anime immerses viewers in Night City, a dystopian metropolis driven by corporations and a clear social divide. This type of setting is everywhere in cyberpunk fiction, but Edgerunners' visual presentation helps set Night City apart from its contemporaries.

More importantly, the OVA series tells an engaging character-driven story that has very few lull moments. The anime follows David, a teenager with a lot of potential who gets dragged into the city's underbelly following a personal tragedy. David's journey is laced with tragedy and foreboding, along with a lot of action and suspense.

Sci-fi typically strives to strike a middle ground between fantasy and realism, although a number of stories prioritize one side over the other. Unlike most sci-fi anime, Space Brothers prioritizes realism above everything else, and the result is a grounded show about the hardship astronauts go through in pursuit of space travel.

The anime revolves around two brothers who, as kids, dreamed of reaching for the stars; one achieved this goal, while the other went down a different path. Now, the latter has a chance to put on that iconic orange suit, and he plans to not let this opportunity slip away.

This 2014 psychological sci-fi thriller gained critical acclaim from across the globe due to its impressive character development and stories within a new, unique world.

A hodgepodge of genres, Gintama mixes sci-fi, comedy, action, and fantasy to create a shonen anime quite unlike anything else on the market. During feudal times, Japan fell at the hands of aliens, who quickly outlawed samurai and started to reshape human society and its technology. Consequently, Edo transformed into a futuristic city with historical sensibilities.

Left with nowhere to go as a former samurai, Gintoki sets up a business designed to take on any requests, and he is accompanied by the straight-laced Shinpachi and the powerful Kagura. Together, they go on many inspired misadventures, producing plenty of laughs and tears along the way. Gintama's blend of genres means it does not fit into one category, and the anime only occasionally explores themes relating to sci-fi.

Astro Boy was about a highly advanced robot abandoned by its creator, and the heroic protagonist goes through many challenges in a timeline set 40 years in the future, being the year 2000. This classic series brings up themes of anti-war, the preservation of nature, and societal discrimination.

Undoubtedly the most highly-anticipated sci-fi anime of Fall 2023, Naoki Urasawa's Pluto manga finally received an adaptation. Based on an Astro Boy storyline, the story follows a detective as he tries to find the killer responsible for a range of murders with both human and robot victims. The manga is considered a masterpiece, so expectations were high for the anime, and it largely managed to live up to expectations.

Pluto envisions a world where humans and robots co-exist, and the latter are so advanced that they can replicate most human emotions. This setup allows the series to deliver realistic and socially relevant commentary on tough concepts like discrimination and PTSD, all the while telling an engaging murder mystery fueled by two gripping and complex figures (the aforementioned detective and Atom, a young robot boy).

When dangerous monsters appear on Earth with the goal to kill all humans, Shinji Ikari gets sucked into a world of mecha-fighting unlike any other. Neon Genesis Evangelion is applauded for its stunning artwork, complex plot, and deep characterization, particularly when it comes to Shinji and Asuka.

NGE has a dark, addicting story that examines the psychological trauma that children forced to carry the weight of humanity's future would naturally develop. The '90s series is ambitious, challenging, and grim, and End of Evangelion brings everything to a close in spectacular fashion. Rebuild of Evangelion is also worth a watch.

With so many books, films, shows, and video games all themed on this story, it's a no-brainer that Ghost in the Shell is one of the greatest sci-fi anime of all time. This Japanese cyberpunk anime is based on the highly-acclaimed manga of the same name, following the story of a technologically advanced cyborg public security agent named Mokoto who is faced with the psychological ideas of what makes humanity and self-identity.

Ghost in the Shell is powerful, beautiful, and filled with incredible music. The 1995 movie tends to hog most of the limelight, and it is the franchise's most artistic project; however, the Stand Alone Complex series arguably represents GiTS' peak in terms of writing and character development.
