While Star Trek is known for its vast `and expandable universe of interrelated shows, films, and spin-offs, there are still a few areas from the canon world that remain untouched.
Many stories from the ST universe plant seeds for convincing follow-ups, only to be left behind as the franchise moves on to bringing out new stories and adventures. Given how the series has restored some of its older characters and plots time and again, it’s unexpected that these five storylines never got their due sequel.
With various series airing today, there’s no better time for Star Trek to go back and revisit these five overlooked gems.
1. Revisiting Eminiar VII’s War Games
“A Taste of Armageddon” to this date is one of Star Trek's strongest social commentaries. It confronted the emotionless, motorized way of war, depicting two planets confined in a computer-simulated dispute, with real fatalities willingly walking to their deaths.
While Captain Kirk’s intrusion brought a momentary stop to the fatal arrangement, what became of Eminiar VII and Vendikar later? Did true harmony follow, or did the standard already established warfare return? This momentary ceasefire left persistent questions that would be suitable if explored in today’s time.
2. The Lucifer encounter that changed everything for Star Trek
One of the boldest stories in Star Trek's animated chapter, "The Magicks of Megas-Tu," risked to venture where no live-action other story of its time could go.
Here, the Enterprise meets Lucien, an alien whose story joins back to Earth's Salem witch trials, with humans labeling him Lucifer. In an unforeseen twist, the episode spins the common "god-as-alien" motif, portraying Lucien not as a devious villain but as a misjudged figure shielding humanity's evolution.
It’s astounding that Star Trek never went back to explore how Lucien’s story interlinks with larger human views. Modern Trek series could effortlessly renew this storyline, using it to draw links with modern-day ideas about faith and worry.
3. Enterprise’s Forgotten Space Vampires
Early in Star Trek: Enterprise, Hoshi Sato’s fears about space travel were at the forefront in "Fight or Flight." Nevertheless, the episode’s most alarming element was the finding of an Axanar vessel full of victims emptied and bled dry of life by an enigmatic alien species.
The attackers, whose worrying actions suggest classic vampire lore, disappeared after this meeting. Though trivial sources later tried involving them with other species, the universe never gave a conclusive answer. Were they wanderers preying all across the galaxy, or part of roughly bigger?
Their quietness since leaves a provoking gap in canon—one that truly warrants a deeper dive.
4. The Dominion’s Unstable Genetic Foundation
During Deep Space Nine, the Dominion’s grasp on the Jem’Hadar and Vorta seemed stiff, thanks to hereditary engineering and psychological rule. However, gaps infrequently showed. One Jem’Hadar lacked reliance on ketracel-white, while Weyoun clones exhibited opposing traits.
These subtle distinctions implied susceptibility in the Dominion’s power structure, yet the universe never fully dealt with the probable outcomes.
What if Sisko or Starfleet scientists pushed more, trying to interrupt the Changelings' power by shifting their creations' genetic code? Such a plotline could have put more layers to the moral intricacies of the Dominion War, and it boils down to an interesting “what if” situation that is worthy of attention.
5. The Vanishing of the Remans
Star Trek: Nemesis gave us one of the franchise’s most visually notable rivals in the Remans—bat-like, Nosferatu-like beings existing in the shadow of Romulus.
Once their upheaval under Shinzon crumpled, they effectually vanished from the universe. With a few series and timelines hardly mentioning them, this leaves fans to question whether they were smeared out or simply overlooked.
Given how rich their story could be, it feels like a wasted occasion that they’ve yet to resurface, specifically in newer Star Trek series that investigate post-Romulan politics.
Star Trek has always outdone itself by looking at broader and more interesting storylines—but occasionally, some of the stories felt as though they were left mid-way without a definite conclusion.
Whether it’s overlooked characters, civilizations on the edge, or unanswered moral problems, these five stories offer prime openings to revisit the past and give fans the sequels they’ve long been waiting for.
