It’s always been a voyage of discovery withStar Trek, which means it wasmore about exploration and diplomacythan blowing things up. The adventures of the Federation and their dedicated officers have included several races other than humans, and there are so many throughout the universe that it’s impossible to tell the story of every single one.

There are a few alien races inStar Trekthat might have been intended solely for plot development or to help make the setting more immersive, but those few moments on screen were compelling enough to make the viewer want more lore, more history, and maybe even a more prominent role in a modern series. Here are a few of the alien races from theStar Trekuniverse that deserve more attention.

7The Deltans

The Deltan race, represented in the first movie in the franchise by a character named Ilia, doesn’t appear as part of Starfleet crews very often. Their near-supernatural powers of sexual attraction make it mandatory that they take a vow of celibacy before serving on a starship.

The script ofStar Trek: The Motion Picturehas an interesting history. It stands in for what would have been the fourth season of the originalStar Trektelevision series, and alsoserved as a template for the settingand how several characters inThe Next Generationwould look. That’s partly why the Deltans share certain distinctive traits with the Betazoids, such as deep intuitive abilities and increased powers of physical persuasion.

6The Children of the Horta

As for an interesting race, how about one that proves sentient life doesn’t have to be carbon-based? In the TOS episode “Devil In The Dark,” the Horta first appears as a malevolent force harassing a mining colony, but further study on the part of the science officer of the USS Enterprise discovers its secret.

The Horta is a silicone-based life form, one that is able to move through, eat, and even breathe rocks and other solid or toxic matter. When the Enterprise left the colony, the miners and baby Hortas were just getting started on what looked like a beautiful friendship, but viewers never heard about them again. It’s high time audiences checked in on this species.

5The Reman

Viewers heard a lot about the Romulan race as distant relatives of the Vulcans and one of Starfleet’s sworn enemies, but not nearly as much about the Reman. They’ve only appeared in one movie thateveryone wants to forget aboutand two episodes ofStar Trek: Enterprise.But considering how close they are to some of the most dangerous villains in the franchise, there should be more for them to do.

The Reman are residents of the Romulan star system, and have been forced to work as slaves in the Romulan dilithium mines. According to some lore, they occasionally rebel and take over old or abandoned Romulan settlements. Perhaps if they wanted to join the Federation and be free of the Romulans, Starfleet would be willing to help them, which could be a plot point in a movie that people might actually want to see.

4The Whale Singers

There’s a lot of weird stuff out there in the galaxy that defies explanation, and this is the extent of information the viewer ever gets for the Whale Singers fromStar Trek IV: The Voyage Home.This race is never even named, and their odd, faceless spacecraft is only ever referred to as “the probe.”

After the humpback whales confirm that rumors of their extinction have been greatly exaggerated, the probe quietly returns to deep space from whence it came. Humanity was so grateful to be left alone that no further questions were asked. As theStar Trekuniverse continues to expand into the Delta Quadrant and beyond, however, how cool would it be to find the Whale Singers?

3The Orions

These characters always seem to get shoved into a script as sex objects or background decor, so how about a real story to even out the negative attention? ModernStar Trekseems to have recognized that the Orions haven’t been given any kind of history or backstory considering their screen time, and there are new characters that do more than gyrate to dramatic music.

The fact is, though, that the Orions are a race of adventurers, pirates, smugglers,and other exciting professionsthat are always fun characters in stories. The Orion Syndicate was the closest they ever came to a functioning government, butDiscovery’s storyline involving the Emerald Chain and Minister Osyraa gave some more depth to this race that audiences would love to see continue to evolve. There are a few male Orions — maybe fans can get a story about them, too?

2The Jem’Hadar

One of the more aggressive and generally unpleasant races that were introduced to theStar Trekuniverse viaDeep Space 9, the Jem’Hadar are from the Gamma Quadrant and represent the Dominion. Not as just another race, however, but as their genetically engineered shock troops. They are trained and bred to see the shape-shifting rulers of the Dominion as gods.

Originally designed as clones, the Jem’Haddar were later given more individual personalities, and by the time they appeared in the DS9 episode that was also named after them, each had individual traits. An interesting story about the Jem-Hadar could be one of freedom and rebellion.

1The Organians

This alien race makes one appearance in the classic show in an episode called “Errand of Mercy.” Captain Kirk and his crew have arrived at the planet of Organia, which isn’t exactly primitive, but seems to be arrested in a state of cultural stagnation and looks similar to the Middle Ages of Earth.

This makes the population vulnerable to the marauding Klingons, who are on the verge of starting an intergalactic war, and the Enterprise is sent to intervene and secure Organia for its strategic importance. The Organians turn the tables on the less advanced races, however, and compared to their power that includes everyone. Could this race of pure energy be related to other powerful races in theStar Trekuniverse, like the Q? It would be interesting to find out.
