As a result of the fact Star Trek is a television show, a low information density medium, we often end up not learning much about any of the alien races and their culture. Sure, the Klingons got their "Heart of Glory," where we learned exactly how they thought, how they looked at the world and behaved, but there are many other races that didn't receive that kind of characterization or development. For instance, despite their regular and persistent use, I don't think the Romulans have ever received their "Heart of Glory." This, despite the fact they have been a part of the Star Trek universe from the beginning (they've actually been around slightly longer than the Klingons!) and were the main villains of
two movies.
1. Deltans
It's easy to overlook the Deltans, because they never made any appearances beyond their initial one. For one thing, the idea was modified and became the Betazoids for TNG. Second, they are associated with "The Motion Picture," a very unpopular part of Trek lore.
But the Deltans are interesting and shouldn't be discarded. For one thing, they are a culture that considers humans to be "sexually immature." What exactly does this mean? What would a "sexually mature" society, one that has "grown up" about sex, actually be like?
Consider: there are a ton of euphemisms in our language for sex and sexual body parts (penises, breasts), and also for death. This isn't a coincidence, since cultures always create a myriad of terms to not directly discuss something they're not comfortable with.
As fundamentally sensual beings, the Deltans were actually very different from Betazoids. For one thing, according to the Gene Roddenberry novelization, Kirk always periodically imagined Ilia naked uncontrollably, for instance. No wonder they had to take a vow of celibacy!
2. Zakdorn
We first see the Zakdorn in "Peak Performance," and we learn almost everything we know about them from that episode: they're considered the greatest natural tactical minds in the universe, yet they haven't been in an actual combat for a very long time, because their reputation prevents possible aggressors from attacking them.
Mr. Worf contemptuously said, "If it isn't tested, their reputation is meaningless." Perhaps Worf is right, but I would have liked to see.
It's hard to say what the Zakdorn are actually like, or what a "garden variety" Zakdorn temperment is, as we've only really seen two: one was the swishy, excitable, arrogant Kolrami from "Peak Performance," and the other was a completely heterosexual junkyard owner in "Unification" that seemed like he was perpetually on Valium. Kolrami was able to defeat Data at a game like Stratagema because there were only a limited number of moves possible and Kolrami could antipate them all...however, when Data redefined his objective (to just fight to a draw) the game continued perpetually because Kolrami couldn't figure out his opponent's intentions.
This seems to be the way to defeat the Zakdorn, despite their very scary tactical edge: their weakness isn't so much that they are startled by unexpected tactics, which doesn't seem like a problem they'd have, but rather, their ability to out-think enemies comes from understanding their motives. If you can "fake out" a Zakdorn, or make them think you want something other than what you really want, you could probably out-think them.
One possible opportunity to use the Zakdorn emerged during Deep Space Nine: what if the Zakdorn, like the Breen and Cardassians, defected to become members of the Dominion? Now that would have been terrifying, to have the Dominion charging into battle led by the greatest strategic minds. For that matter, where were the Zakdorn, anyway? You'd imagine the Federation would have asked for their help in the greatest military problem
in Federation history.
One thing I loved about Deep Space Nine was the feeling that during the Dominion War, there was a feeling a million things were going on at the same time. For the first time, the Trek universe acquired
scope. This was in contrast to Voyager, where I never really
believed in the Delta Quadrant; it was like the space Voyager passed through ceased to exist after they left!
One of the more impressive opportunities not pursued was the conquest of Betazed. I mean, here's a famous planet known for being sensualist and sexy, and they've been taken over by a group as ruthless as the Dominion. Surely there's a story there...
3. TholiansThe Tholians, like the Breen, were
mentioned far more than they actually
appeared. Which is a shame, because they're a fascinating opportunity, a "villain" race with a pedigree going back to the Original Series. This is extremely rare, because the overwhelming number of recurring alien races the original Trek gave us were usually pretty ridiculous looking, to the point where later incarnations of Trek went out of their way to not use or even mention them.
Take the Andorians, for instance. The writers of TNG deliberately stated in no uncertain terms
on a number of occasions that there were
no Andorians on the Galaxy-class Enterprise. There was even an interview with a head writer on TNG, when asked if any Andorians would show up on TNG, "Sorry, we don't do antennae on this show." I certainly don't mourn the loss of the Andorians, and in fact I'm a little baffled by their use in
Enterprise. No matter how much goodwill one has towards the original series, no matter how much fondness or admiration, it will not change the fact that the Andorians
look absolutely silly. A lesson on the dangers of nostalgia that many members of other fandoms have yet to learn, but I digress.
As for the Tholians, not only did they have a great look (or at least they were suggested to look really strange), they were sincerely menacing and mysterious, and had the good luck to appear in one of the most memorable episodes of the original series. The Tholians are, further, something very, very rare in Star Trek: an alien race that truly is alien. At times it seems that the "alien races" are just substitute human cultures. One critique of the Star Trek universe is, like the universes of
Foundation or
Dune, it could be rewritten so that all the alien races are different human civilizations spread across the universe, and very little of the Trek universe would have to be changed.
Often, real-world human cultures were used as the basis for Star Trek aliens: the Klingons are equal parts Japanese and Norse, and the Ferengi are even explicitly compared to 19th Century Yankee traders. While the Romulans derive their names from Rome, their culture is more like the totalitarian dictatorships of the 20th Century, a world ruled in equal parts by the military and the secret police.
The exception are the Borg, who have a radically different basis that is only possible by science fiction, who are much more what alien races are like in written, serious science fiction.
One of my favorite ideas for the Tholians came from Peter David's
New Frontier Trek novels. The Tholians experience time in a nonlinear fashion, radically different from other species. For instance, when the Tholians attack a ship without obvious provocation, it may be not be because of something they have done, but something that they are
going to do in the future.
Incidentally, I always thought the "updated" makeup designs in
Enterprise looked silly. The CGI "Jurassic Park" Gorn, for instance, looked especially laughable. But in the case of Tholians, they was nothing short of spectacular. My reaction was "oh, so that's what they looked like, all along!"
4. NausicaansThe Nausicaans made quite an impression when they showed up in "Tapestry" as the silent, brooding bruisers that stabbed Picard from the back and caused him to need his artificial heart. They were something that few Trek villains often become: truly intimidating, able to arouse fear. It would be fascinating to see them again. It was often mentioned in later series that the Nausicaans were used as hired thugs, bodyguards and muscle for criminal operations, a role that somehow suits them perfectly.
In fact, it's really very strange we haven't seen these guys much, considering how powerful their debut was, and how hard-up TNG was for new enemies. All but one of their appearances (just let me get to
that) featured the same Nausicaan hardcore mystique: my personal favorite was the scene in Quark's bar where the Nausicaans amused themselves by throwing darts at the chest of one of their own (who it should be said, took it like a champ)!
Yes, I am aware there was an episode of Enterprise that featured the Nausicaans, but like everything Enterprise, it took the potential of these new villains and squandered it. For one thing, they colored the Nausicaans
pink and made them much smaller! Even the makeup was different; they looked much more like ridiculous parrotmen.
5. BynarsWhat was really amazing was, the Bynars were pushed forward in a lot of early TNG promotional material as one of the new aliens created for the series, along with the Betazoids and Ferengi.
This makes their absence all the more puzzling from every episode except their debut. I mean, they couldn't just have a few Bynar pairs running around in a toolbelt fixing things in corridor shots, on starbases or ships? They couldn't put a couple Bynars in a Federation Council chamber or diplomacy room? (Yes, I'm aware it was never technically stated the Bynars were Federation members, but still.)
The reason I like the Bynars is because they have a truly alien culture and biology as opposed to just being Japanese Samurai or Communists in outer space. They view all information in terms of 0 or 1. All of them are linked to a massive computer network on their planet, and they live as identical pairs that complete each other's sentences, and even their names are in binary code. Surely
something can be done with a race that unique.
