The 1980s were a golden age for science fiction, with iconic movies like Back to the Future and books like Ender's Game defining the genre. But the small screen also had its share of gems, many of which have since faded into obscurity. While shows like Star Trek: The Next Generation remain beloved, a host of other series—from animated adventures to live-action oddities—have been largely forgotten. These shows may not have the name recognition of their peers, but they still hold up remarkably well today, offering a nostalgic trip back to a time when sci-fi was bold, experimental, and unafraid to be weird.
It's an exaggeration to say that nobody remembers these shows, but it's true that they've slipped from the mainstream consciousness. For those who grew up in the '80s, they might evoke fond memories of Saturday mornings or after-school viewing. For new audiences, they offer a chance to discover the creativity and charm of a bygone era. Here are ten forgotten '80s sci-fi shows that deserve a second look.
The Adventures of the Galaxy Rangers (1986)
This American cartoon was a trailblazer, blending sci-fi with Western tropes in a way that felt fresh and exciting. The Adventures of the Galaxy Rangers followed four elite rangers who used unique abilities to protect law and order across space colonies. It was one of the first U.S. shows to feature anime-style animation, with the actual animation done by a Japanese studio. Despite its intelligent writing and fun characters, the series was canceled due to poor viewership and toy sales—a common fate for '80s cartoons. Today, it's a cult favorite that deserves a revival.
Centurions (1986)
Another anime-influenced gem, Centurions started as a five-part miniseries before expanding into a 60-episode series. It followed elite soldiers who used powerful mecha exoskeletons to battle evil cyborgs. While the show was clearly designed to sell toys (Kenner produced a line of action figures), it was surprisingly well-written and visually appealing. The unique American take on mecha anime tropes makes it a fascinating watch for genre fans. It was canceled after one season, but its nostalgic charm endures.
Benji, Zax & the Alien Prince (1983–1984)
Not all '80s sci-fi was animated. This live-action family show featured Benji, the iconic dog, who befriends an alien prince and his droid on Earth. The story begins on a distant planet where a tyrant kills the king and imprisons the queen, forcing the prince to flee. Despite Benji's fame, the show was poorly received at the time and quickly forgotten. But with hindsight, it's a cute, imaginative Saturday morning classic that offers wholesome fun for the whole family.
Dr. Slump – Arale-chan (1981–1986)
Before Dragon Ball, Akira Toriyama created Dr. Slump, a whimsical manga about a quirky inventor and his android daughter, Arale. The first anime adaptation, Dr. Slump – Arale-chan, is a vibrant, high-energy comedy filled with slapstick, puns, and chaotic joy. Its timeless visual design and clever humor make it one of the best anime of the '80s, yet it remains overshadowed by Toriyama's later work. For fans of Dragon Ball, this is a must-see.
Guest from the Future (1984)
This Soviet miniseries was a massive hit in its home country but barely known elsewhere. It follows a schoolboy who finds a time machine and teams up with Alisa, a scientist from the future, to stop space pirates from stealing a mind-reading device. Part time-travel adventure, part detective story, it's a charming, high-stakes tale with a ton of heart. Even after 40 years, it remains perfect family viewing.
These shows are just the tip of the iceberg. For more hidden gems, check out our list of forgotten spy shows that aged like fine wine or explore Marvel's hidden gems.
