Do you like sci-fi or sci-fi anime? In this guide we are going to share the best of the genre, along with a complete list of good anime that end up going unnoticed by people.
Sci-fi, or science fiction, is a genre of speculative animes that is based on imagination. Generally, they explore a new world, whether in the future or in the past, as well as 他の惑星 and alternative lands.
The genre commonly showcases humanity's curiosity and innovation as they struggle with new technologies, new societies or new frontiers in space. Most of the time these anime are theoretically possible by science.

Steins;Gate - The best time travel Sci-Fi anime
Without a doubt, the best science fiction anime involving time travel is called Steins;Gate. A perfect work with a lot of psychological thriller, mystery, and filled with references to the otaku world, in addition to references to the real world.
The anime tells the story of a group of young people who end up creating a time machine using a microwave, it seems confusing and crazy but WATCH! This is undoubtedly the best anime I have watched in my entire life! It's hard to give a synopsis without spoilers.
The anime consists of 24 episodes plus an OVA, followed by a movie and a spin-off second season that shows an alternative timeline that is relevant to the main story, where the events lead to the results of the first season.

Gintama - A Sci-Fi Comedy
Gintama is a huge success in Japan, being one of the greatest comedy animes of all time, focusing a lot on making parodies and references. In this anime, we have a universe full of samurais, alienígenas, and other eye-catching creatures.
Several space races collectively known as the Amanto arrived in the age of the samurai. Amanto's highly advanced technology resulted in total conquest and severe economic change. Now, former samurai like Gintoki fend for themselves to survive.
Gintoki's profession is that of a yorozuya, which consists of doing any job for money. However, he is unmotivated and spends most of the day on the couch reading the latest edition of Jump while being tormented by his employees Shinpachi and Kagura.

Sidonia no Kishi - Knights of Sidonia
An alien race called the Gauna has destroyed Earth, leaving humanity struggling to survive, aboard the starship Sidonia. Even though a century has passed since the last encounter with the Gauna, military service is mandatory.
For Nagate Tanikaze, whose grandfather has secretly hidden him in Sidonia's forgotten bowels, it's a strange new world as he is forced to come to the surface. However, their recruitment arrives just in time, as the Gauna have suddenly reappeared.
Despite the CG, once you get used to it, the anime holds you and takes you to great emotions, with a good dash of action, romance and twists. Give this great sci-fi anime a try.
In addition to Sidonia no Kishi, I want to make honorable mentions to other anime involving space battles and meka, in order to avoid similar anime on the list. Please give a chance to the anime Tengen Toppa Gurren Lagann and Aldnoah Zero.

Yakusoku no Neverland - The farm anime
Emma, Norman, Ray and many other “siblings” live in an orphanage isolated from the outside world. They live an enchanted life surrounded by friends and protected by Mama, their caretaker, all in the hope of finding a home by the age of 12.
The only rule is that they should never venture outside the gate that isolates them from the rest of society, for dangers await them. But one day, the children learn the true horror of what is reserved for their short lives...
In this universe, creatures evolved and became predators of humans, through an agreement between them, these creatures grow children on farms similar to daycare centers in order to market them as food.

Code Geass - Overthrowing an Empire
In this universe much of the world is dominated by an empire called the Britannian. Japan is one of its domains, it receives the name of area 11 and the Japanese suffer prejudice in such a way that they are not called Japanese, but the eleven.
The forgotten son of Emperor Lelouch who is very intelligent, outraged by all the events of the world, one day ends up rebelling against the empire, engaging in a vast battleground mental using the power that was granted to him.
In this universe full of Mekas, Lelouch receives a power that allows him to give an order to a person by looking into their eyes. He uses such an ability to manipulate people on both sides, creating a massive rebellion under the name of a masked man named Zero.

Boku no Hero Academia - The world of heroes
In this universe, more than 70% of the population has some special ability, some use these abilities to become heroes. The protagonist Midoriya Izuku was born without any ability, but he is passionate about heroes and really wants to be one of them.
One day the super hero most powerful and famous in the world, All Might, offers a golden opportunity to the boy. Midoriya has the chance to inherit All Might's power to be trained and become his successor.
With that, Midoriya will study at the greatest Hero school in order to enhance his skills and fight against villains. Boku no Hero is a highly successful anime with several seasons that you probably already know. Otherwise... Hurry up and watch it!
It's worth noting that there are other anime in the fiction genre with heroes. We can briefly mention the case of One Punch Man, an anime with a lot of comedy and action. I decided to mention it briefly here to avoid listing several similar anime.

Dr.Stone - If the world loses everything?
Several thousand years after a mysterious phenomenon that turns all of humanity to stone, the extraordinarily intelligent and science-oriented boy Senku Ishigami awakens.
Facing a world of stone and the total collapse of civilization, Senku decides to use science to rebuild the world. Starting with his super strong childhood friend Taiju Oki, who awakened at the same time, they will begin to rebuild civilization from scratch...
The anime portrays human evolution and inventions well, has a very exciting story involving conflicts with people who don't want human evolution, natives who survived the freezing and much more.

Space Brothers - Uchuu Kyoudai
One of my favorite animes and one of the most popular in Japan that goes unnoticed by Western society. In this everyday story, we are in the shoes of Mutta, a 30-year-old unemployed man with a childhood dream of going to space.
His younger brother Hibito was able to fulfill that dream by becoming an astronaut. Mutta, despite being old, tries to reach his brother by enlisting to be an astronaut in order to go to Mars. It sounds like a different theme, but it's very exciting.
With the synopsis alone I'm not able to hold your attention, but this anime is simply epic! Mixing different genres, with a lot of drama and psychological, with a more realistic comedy and footprint. Watch the anime that won the Japan Weekly TOP1 several times.

Psycho-Pass - Controlled by a system
In Psychi-Pass a system called Sibyl is responsible for the security of Japan. through its technology it manages to identify people's criminal coefficient, preventing them from committing crimes before they even think about doing so.
This creates an entirely different universe where people need to avoid stress if they don't need to go to the hospital. An all technological world, Dark and Punk, where a kind protagonist ends up being recommended to serve as inspector.
Inspectors work alongside latent criminals called executioners, who need to capture potential criminals, using a weapon that only fires if the person's coefficient is high. The weapon can stun or kill according to value.

Kiseijuu - The sci-fi anime of parasites
In this anime, parasites invade the 人間の脳, taking over their lives and living in hiding while feeding on other humans. Thousands of murders have been happening and worrying society.
In the meantime, a young man named Shinichi Izumi ends up being attacked by a parasite, but manages to defend himself using a headset, causing the parasite to lodge only in his right hand.
For Shinichi's survival and the parasite itself lodged in his right hand, they both agree to coexist and work together to fight the parasites that are murdering humans. Will this work?
