Top 20 Sci Fi Anime You Need To Watch ( Updated 2021 )

From interstellar adventures and intense space battles to alien invasions and AI taking over the world, sci-fi shows give us everything our minds envision outside the bounds of everyday science. And while live-action series and movies take most of the praise in the genre, sci-fi anime has proven on multiple occasions that it can be just as good if not better.

Today, we countdown the 20 best sci-fi anime of all time in no particular order.

1. Ergo Proxy

2. Planetes

Amazon.com: Planetes Anime Songs: Appstore for Android

In 2075, advancements in science and technology have made space travel just another part of everyday human life, allowing for large space corporations’ formation. In the Debris Section of one such company, a new employee Ai Tanabe is about to realize how underappreciated, underfunded, and understaffed her space garbage department is. Meanwhile, she becomes acquainted with other department members, each with a unique personality, hopes, and dreams.

Planetes approaches the sci-fi world differently, telling a fascinating story of ordinary people’s dreams in space rather than the soldiers, scientists, and explorers we are used to.

3. World Trigger

World Trigger follows humanity’s fight for survival and the adventures of Osamu Mikumo when he gets involved with a mysterious new student who happens to be a Neighbor in disguise.

Although this Shonen anime starts off slow in the first couple of episodes, it tells an exciting story by introducing a protagonist who struggles with himself and his mistakes.

4. Psycho-Pass

When Akane Tsunemori joins the inspector-enforcer world, she soon learns the Sibyl System is not as perfect as previously assumed.

Following the story of Akane Tsunemori and her quest for justice, Psycho-Pass showcases that the concept of a perfect society is just but an illusion.

The world is invaded by a parasitic alien species that infiltrate humanity by taking over vulnerable individuals’ brains, obtaining complete control over their hosts.

Realizing that the city’s fate rests on their shoulders, the duo embarks on a mission to save Lux from all-out war and total collapse.

Luckily for him, a series of mysterious events lead the trio to realize that the device can send emails to the past.

Steins: Gate is an excellent piece of work, with a complex plot that unfolds bit by bit towards a satisfying ending. And while its art is pretty good, the fantastic plot is backed up by well-written and easily likable characters that make the story more compelling.
