Star Trek: The Animated Series Episode Re-Watch: How Sharper Than a Serpent’s Tooth

A spoiler warning graphic.

Spoiler Warning: There are spoilers ahead for Star Trek: The Animated Series as well as The Original Series and Voyager Season 2.

I haven’t really talked about The Animated Series very much here on the website, but to mark the fiftieth anniversary of the episode How Sharper Than a Serpent’s Tooth – which premiered on this day back in 1974 – I thought it might be a bit of fun to step back in time to Star Trek’s first foray into the world of animation. It’s actually been a long time since I last watched this episode (or really any of The Animated Series), so we’re going into this re-watch almost completely blind!

I have to confess that I have a bit of a psychological block when it comes to The Animated Series. From the late ’80s to the early 2000s, the official line from Gene Roddenberry, Gulf+Western, Viacom, and Star Trek’s other corporate overlords was that the show was officially “non-canon.” For the purposes of The Next Generation-era Star Trek, nothing in The Animated Series happened, and that’s left me with a lingering feeling about that show that’s difficult to put into words. The era in which I became a Trekkie was the era in which The Animated Series was deemed to be “too low-quality” to be an official part of the franchise. I watched a few episodes here and there in the ’90s, but The Animated Series wasn’t a mainstay on terrestrial TV here in the UK at the time, so I didn’t see it in full until it arrived on DVD in the mid-2000s.

Remember when Star Trek DVD box sets came in chunky plastic cases that were awkward to open?

It was only when the DVD box set was being readied for release that CBS formally ditched the “non-canon” line, by the way, declaring The Animated Series to be a full and official part of the Star Trek franchise once again. At that time, with Enterprise being cancelled, it seemed as if Star Trek might’ve been over – so why not include The Animated Series if it helps shift a few more DVDs? I guess that was the thinking when that decision was taken!

So that’s my background with The Animated Series as we come to this episode re-watch! Although it’s a show I only occasionally dip into, the fiftieth anniversary is still a big deal, and it’s always worth keeping in mind the role The Animated Series played in the history of Star Trek. As re-runs of The Original Series gained traction in the early 1970s, calls grew for Star Trek to be brought back. The Animated Series was a compromise; a way to make new episodes and satisfy the growing fan community without having to commit the money required to re-start production on a live-action show.

And the lack of budget awarded The Animated Series… well, let’s just say it can be obvious! There is a distinctly old-school charm to parts of the show, and the low-budget animation of the time. But The Animated Series can also feel quite janky, especially if you aren’t used to it or if you prefer today’s slicker, computer-animated visual style. I think there’s a real warmth to this style of animation, and the obvious jank just adds to that in my opinion!

As the show that boosted Star Trek during what could’ve been its darkest hour, we owe a lot to The Animated Series for the franchise’s re-birth at the end of the 1970s. The Motion Picture and Star Trek’s subsequent renewal in the ’80s would arguably not have been possible without this show keeping things fresh and growing the audience. Bringing younger eyes to Star Trek through this “Saturday morning cartoon” style bolstered the franchise’s prospects and shouldn’t be understated.

By happy coincidence, the episode I picked for this re-watch happens to be the 100th episode of Star Trek! After 79 episodes of The Original Series there were 22 produced for The Animated Series across two seasons – this being the penultimate one. I know it isn’t a huge deal, but these milestones can feel important.

Onward, then, to the episode How Sharper Than a Serpent’s Tooth!

:-O

The first thing to note is the opening titles! A slightly jazzed-up version of The Orignal Series theme plays, heavy on the horns, and William Shatner gives his usual “these are the voyages” voice-over as Captain Kirk. Hearing it again after not watching either show for a while was a real blast of nostalgia… and we haven’t even got started yet!

The episode proper kicks off with a captian’s log, with Kirk narrating that the Enterprise is tracking a mysterious probe. Lower Decks and Strange New Worlds have brought back the captain’s log as a framing device after the likes of Picard and Discovery used logs much more sparingly, and I have to say I’m glad for that. The captain’s log is an integral part of the franchise, after all!

The opening scene on the bridge sets the stage for the episode – a second probe is coming in, following the same trajectory as the first. Characters created specially for The Animated Series are present: the three-armed, three-legged Arex being a personal favourite of mine! Ensign Walking Bear – a Native American – is at the helm. Both characters (and many others in The Animated Series) were voiced by the late James Doohan, better known for his role as Scotty.

On the viewscreen, the alien probe appears as little more than a smudge of yellow-green – and waddles unconvincingly toward the Enterprise! This is a great example of what I mean about finding charm in the jankiness of The Animated Series; by anyone’s standards, even in the ’70s, this doesn’t look great! But part of the fun of fantasy and sci-fi is getting lost in the setting, looking past things like that, and even using one’s imagination to help suspend disbelief. Sure, the alien probe looks like something you might find in a newborn’s nappy… but so what? It’s an alien probe, dammit, and that’s that!

The alien smudge… I mean probe.

As the Enterprise becomes trapped in a “globular force-field” – which looks like a snow-globe or Christmas bauble from the outside – Spock proclaims it is “fascinating” while Scotty reports to Kirk that he doesn’t know how long the ship can take the strain! Classic lines from the classic crew, and I’m right back there with them. The ship comes to a complete stop while Kirk and the crew decide how to proceed.

The smudge “de-cloaks” to reveal a beautiful spaceship that could be right out of a dozen or more mid-century sci-fi properties! The vibrant shades of red, purple, and blue give it a striking appearance, and the glittering panel at the front makes the vessel stand out. It really is a beautiful ship – and clearly more than a match for the entrapped Enterprise. Though you might not assume so from appearances alone! I love this kind of design; a pre-Star Wars retro sci-fi look, bold in its colour choices. They don’t make ’em like that any more!

I really like this spaceship design.

The Animated Series was also pretty limited with its soundtrack. At this point in the episode, with the Enterprise under attack by the beautiful alien vessel, the show’s only “action theme” plays – and I’d forgotten just how much I love this piece of music, too. It seems to perfectly capture the danger that the crew are in… even if, by this point in The Animated Series’ run, we’d have heard it twenty times or more!

Kirk tries everything – reversing the engines, powering up the shields, and hailing the ship – but running out of options and limited by the globe preventing the Enterprise from moving, he reluctantly orders phasers to fire. Although this also proves ineffective, I like how The Animated Series was still true to Kirk’s character: he was never spoiling for a fight and would look for a peaceful way out where possible.

Kirk only fired on the alien ship when he’d tried everything else.

The new character – Ensign Walking Bear – recognises the ship when it projects a dragon-like design (using something like an early holo-projector, perhaps?) and this seems to give the attacker pause. Pleased that at least one human “remembers” them, they give the crew a chance to succeed – but warn that failure will mean death.

Now we see why Walking Bear was on the bridge, eh? Star Trek always finds uses for redshirts and always has! Even classic episodes like Balance of Terror put secondary characters like this in just the right place to contribute to the story or to building up the lore of the franchise. I’ve been critical of modern Star Trek, sometimes, for nakedly shoehorning in some piece of backstory to a secondary character solely for the purposes of connecting to the main narrative… and I guess in some cases it works better than others. But it’s worth remembering that it’s something the franchise has always done in one form or another.

Kirk and the crew received a message from their attacker.

This Kukulkan – described by Walking Bear as an ancient legendary god of the Aztecs and Mayans – is who’s attacking the Enterprise. I’m reminded of two episodes – one from The Original Series and one produced much later during Voyager’s run. Who Mourns for Adonais? during the second season of The Original Series introduced Kirk and the crew to the “gods” of Ancient Greece. And Tattoo, the Voyager Season 2 episode that saw Chakotay encountering an alien race that his people called the “Sky Spirits.” The stories aren’t identical by any means, but there’s a similarity in the underlying premise of all three.

Midway through a conversation with Kirk, Walking Bear vanishes – as do Scotty, Dr McCoy, and eventually Kirk himself. Spock assumes temporary command of the Enterprise, before the action switches to the kidnapped men aboard Kukulkan’s ship. They seem to be in some kind of holodeck – the room, while plain silvery-grey at first – soon morphs into a landscape filled with trees, and then ultimately a city. There was a vaguely Mayan or Aztec look to this city, which was adorned with several statues of Kukulkan. The statues themselves, though, almost gave me a Chinese or East Asian vibe; dragons are a big part of the folklore of that part of the world, too.

Back on the Enterprise, we get a short scene with Spock and Uhura. Uhura wants to do something to help Kirk, but Spock insists that their priority is to free the Enterprise from Kukulkan’s clutches. It isn’t easy to convey facial expressions with such limited animation, but I think we’re meant to understand that Uhura isn’t thrilled with this response!

Kirk, Walking Bear, and the others try to puzzle out what Kukulkan wants. Using Walking Bear’s knowledge of history, they piece together that Kukulkan tried to instruct several ancient cultures, but that none of them did exactly what the entity wanted. Kirk heads to the top of an Aztec pyramid that has appeared in the middle of the city – which seems to be comprised of elements from several different cultures. For its time, this is a pretty sensitive and historically accurate depiction of Native Americans, Maya, Aztecs, and others. There’s even a mention of the Mayan calendar… giving me flashbacks to the 2012 phenomenon!

Maybe it’s an old memory bubbling under the surface from when I last watched How Sharper Than a Serpent’s Tooth some years ago, or perhaps it was just a pretty obvious story beat, but the fact that the statues could be rotated to generate the signal Kukulkan was looking for wasn’t exactly a surprise! It seemed like something the crew figured out pretty easily, so maybe I shouldn’t be patting myself on the back too hard for figuring it out. It felt like a puzzle you might have to solve in a video game like Tomb Raider!

Kukulkan makes their appearance after Kirk solved the (easy) puzzle, but complains yet again that they have been forgotten. I like the design of Kukulkan – appearing as a colourful winged snake with a kind of mane or frill. I wouldn’t say the design was “intimidating” as it appears in the show, but I daresay if I came face to face with a real-life Kukulkan I’d be quite frightened! It was neat, at any rate.

Kirk and the others are then transported to a “zoo,” one populated by a number of other aliens and animals. Kukulkan’s convoluted explanation is that they’re the last member of a race that wiped itself out, and that they keep these creatures in cages, using technology to create “mental worlds” for them to inhabit. Dr McCoy is shocked that one of the creatures is a Capellan power-cat – an animal that’s notorious for hating being kept in captivity. The power-cat is adorable, by the way, and I won’t hear a bad word said about it.

Kirk argues that Kukulkan has no right to interfere with humanity or any other culture – but all this does is enrage them. Kukulkan hisses like a snake and seemingly attacks the crew, while back on the Enterprise Spock seems to have found a way out of the globe force-field. I wasn’t wild about Kukulkan’s explanation here; it seemed a bit basic. And it runs into the problem that other, similarly powerful aliens encounter in other stories: it should be clear that humanity has changed a lot over the centuries, growing, evolving, developing new technologies – and in this case, becoming more peaceful. Sure, the Enterprise fired phasers – but as Kirk points out, only in self-defence.

Spock’s plan works – because of course it does! – and the Enterprise is able to break free from the trap. It’s always fun to see Arex in action on the bridge, and at the time this three-limbed alien could really only be created for animation. The Animated Series, in that sense, gave Star Trek a chance to branch out beyond the make-up and basic prosthetics of its original incarnation. Kukulkan is also a great example of this: live-action couldn’t really have made a similar-looking alien – not with the budget usually set for a single episode of Star Trek, at any rate!

After Bones and Kirk free the power-cat from captivity, it runs wild. Using its high-voltage fur(?) it threatens Kukulkan, whose ship’s power has been damaged following an attack by the Enterprise. Kirk intervenes, subduing the power-cat with a hypospray, demonstrating to Kukulkan that he doesn’t wish the entity any harm, despite the damage that has been caused.

What follows is a fairly typical Star Trek dialogue, with Kirk and the others emphasising how much humanity has grown since Kukulkan visited centuries earlier. Kirk rejects the idea of being caged or led around like the animals in the zoo, and Kukulkan capitulates, realising that humanity no longer needs or wants to associate with them. I actually felt a bit sad for Kukulkan in this moment – their dreams of having sentient companions instead of just animals seemed to be shattered, and being told “we no longer need you” is just harsh to hear!

Kirk says that the price for Kukulkan sharing its knowledge was too high, and back on the Enterprise he and Spock ponder the implications of several of Earth’s civilisations having contact with this ancient alien – as well as the irony that, at the end of the day, Kukulkan was just lonely and seeking companionship. The danger averted, Kukulkan withdraws, and the credits roll.

All in all, this was a fun episode to re-visit. I adored the designs of Kukulkan’s ship and the entity itself, as well as some of the very alien critters in the zoo. The power-cat is something I’d love to see make a re-appearance in modern Star Trek; I can see it being a ton of fun to depict in live-action! But then again I’m a cat lover, so I suppose I would say that.

This was a story that felt very “Star Trek.” An ancient alien visited humanity in the past, and returns only to be disappointed with the war-like nature of humans. Kirk and the crew had to intervene to show that their perceptions weren’t entirely right, and that humanity has developed beyond the need for gods and deities. It’s far from the only episode to touch on themes like this – but something about the design of Kukulkan as this winged, dragon-like serpent, and its connection to real cultures like the Maya and Aztecs, gave the story some more depth. At the very least, Kukulkan stands out from the pack of Star Trek aliens with prosthetic noses and foreheads!

As a bit of background, How Sharper Than a Serpent’s Tooth was submitted as the episode to be assessed when The Animated Series was nominated for a Daytime Emmy Award in 1975; the series would go on to win that award. It’s the only time a Star Trek show has won the award for “Best Series,” so this episode turned out to be quite influential! It also marks Spock’s 100th Star Trek appearance, and as noted above is the franchise’s 100th instalment.

It was a blast to go back to The Animated Series for the first time in years, and I’m glad that I got to mark the milestone anniversary of at least one of its episodes. Very few TV shows – and even fewer cartoons – can claim to have such a legacy half a century after their first broadcast, but The Animated Series really does occupy a unique place in Star Trek’s history. I hope you’ll join me in celebrating this fun show as we mark the fiftieth anniversary of the episode How Sharper Than a Serpent’s Tooth.

So which episode of The Animated Series should we look at next? I’ve always had a soft spot for the frankly bizarre episode The Magicks of Megas-Tu… a story that no other franchise would dare attempt, especially not nowadays! I’ve also never written a proper episode re-watch for The Original Series here on the website, despite being up and running for almost five years. We’ll have to rectify that one day, too. But for now, I hope you’ve enjoyed stepping back in time with me. And until next time: Live Long and Prosper!

Five planets that Star Trek probably won’t revisit any time soon!

Spoiler Warning: There are spoilers ahead for the following Star Trek productions: The Original Series Season 2, The Animated Series, The Next Generation Season 1, Voyager Season 2, Star Trek 2009, Picard Season 1, Discovery Season 3, and Lower Decks Season 2.

I wouldn’t even like to guess how many different planets (and other planetary bodies) have been visited across all 800+ episodes and films in the Star Trek franchise! It must be a lot… maybe someone has been keeping a tally, but I certainly haven’t! There are some worlds that we’ve visited more than others – Bajor, Qo’noS, and of course Earth all spring to mind. But there are some planets that, for one reason or another, are best left behind in the franchise’s past.

As Star Trek moves on to bigger and better things, some planets – and their inhabitants – seem outdated, or perhaps the concept behind the planet was never a good one to begin with. Today I thought it could be interesting to consider five examples of planets that Star Trek will almost certainly never revisit!

Planet #1:
Ekos

The USS Enterprise in orbit of Ekos (as it originally appeared).

Ekos was created for The Orignal Series Season 2 episode Patterns of Force, but you might know it better as “that Nazi planet.” There’s definitely scope for the Star Trek franchise to tackle authoritarianism, fascism, and even Nazism – and as recently as 2004, Enterprise put its own spin on the “Star Trek-versus-Nazis” concept. But there are a few deeply unsettling things about Ekos, and how its Nazi-inspired government came to power.

First of all we need a brief history lesson! In the 1960s, when Patterns of Force was created, some historians, economists, and other political scientists regarded Nazi Germany as an “efficient” state. Resting all power in a single individual, they argued, made for a powerful government that could be run very efficiently. In Patterns of Force, Federation anthropologist/historian John Gill cites this theory as the reason for introducing Nazism to the Ekosians.

Ekos is also known as “Planet of the Nazis.”

That theory was flat-out wrong, and even by the 1970s and 1980s, the flawed thinking that led to the myth of “Nazi efficiency” had been exposed and thoroughly debunked. In short, Nazi Germany was a very poorly-run government, with a handful of cronies of the führer wielding disproportionate levels of power, and micromanagement in certain departments and industries majorly hampering the state’s industrial output. How this myth ever came to be as widely believed as it was is, in some respects, a bit of a mystery. But suffice to say that the central conceit behind Patterns of Force has been exposed as a falsehood.

John Gill, the academic at the heart of the story, also represents a very distinct kind of betrayal of Federation values, taking things to perhaps the most unpleasant extreme possible. Star Trek has never shied away from showing us flawed human beings and Federation officials, but Gill is a step too far, and Patterns of Force can be an uncomfortable watch for many Trekkies.

John Gill, the Federation historian who became the Führer of Ekos.

Though it might be interesting, in some respects, to revisit Ekos in the 24th, 25th, or 32nd Centuries to see how things had progressed, in many ways it’s a planet – and a story concept – that should probably remain on the sidelines. Modern Star Trek can tell far more subtle stories about authoritarianism, racism, and the like without needing to resort to overt depictions of Federation-sponsored Nazism.

Patterns of Force is based on an outdated concept, and while it was brought to screen quite well by the standards of The Original Series, with some clever visual effects for the time and some surprisingly accurate costumes, it feels like an anachronism overall. This is one best left behind in the 1960s!

Planet #2:
Megas-Tu

The USS Enterprise near Megas-Tu.

The Animated Series had some very wacky sci-fi concepts. Taking Star Trek away from live-action meant that the franchise was no longer confined by the limitations of practical special effects, and thus it was possible to depict things like a 40-foot tall clone of Spock, an entirely underwater civilisation, or, in The Magicks of Megas-Tu, an alternate universe where magic is real and science is not.

I’ve always had a soft spot for The Magicks of Megas-Tu, and I think it’s an episode that every Trekkie should watch at least once. It’s an example of mid-century sci-fi at its wackiest, but it manages to retain a Star Trek tone throughout the very unusual adventure that Captain Kirk and the crew of the Enterprise find themselves on.

A group of Megans departing their homeworld.

With the possible exception of Lower Decks, which has been more willing to explore some of the stranger elements of classic Star Trek, I can’t imagine Megas-Tu ever making another Star Trek appearance. How would it fit in Discovery, for example, or Picard? The tone of modern Star Trek is just too different – and even by the time of The Next Generation, Star Trek had moved away from concepts like this. Megas-Tu feels homeless, in a sense, in a franchise that has moved on.

That isn’t to say that it was a bad concept when it was first developed, but like several ideas from The Original Series and The Animated Series, magic and fantasy just seem to be a step too far for a franchise that has retained its esoteric side and sense of fun, but refocused them into more science-based stories rather than stories that use literal magic and fantasy as core elements.

Cheers!

It’s hard to see how a story about Megas-Tu could fit in with modern Star Trek. Audience expectations have shifted when it comes to science-fiction, and with the Star Trek franchise moving away from stories like The Magicks of Megas-Tu, it seems very unlikely that we’ll see anything like it in the franchise anytime soon.

There’s also the in-universe problem of travelling to the Megans’ universe, and while technobabble can always be created to explain away these things, it seems like a bit of a stretch. It’s possible we’ll get more references to The Animated SeriesPicard Season 1 made reference to the Kzinti, for example. But a full revisit to Megas-Tu is probably off the table!

Planet #3:
Ligon II

Ligon II.

The planet that inspired me to put together this list, Ligon II was visited in Code of Honor, the notorious Season 1 episode of The Next Generation that has been widely criticised for its use of racial stereotypes. The Ligonians encapsulated stereotypes of Africans and African-Americans, and Code of Honor has to be one of the worst episodes of The Next Generation as a result.

Some stories from past iterations of the franchise are open to redemption; to being revisited to right the wrongs of the past. We’ve seen this, to an extent, with certain characters in modern Star Trek who saw much-needed development or expansions of incomplete arcs. We’ve also seen Lower Decks revisit planets like Beta III to comment on Starfleet’s somewhat chaotic approach to first contact.

Code of Honor has been widely criticised for stereotyping.

But Code of Honor and the episode’s depiction of the Ligonians feels so utterly wrong that it’s irredeemable. There are some parts of Star Trek’s past that the franchise brushes under the carpet, choosing to ignore and even overwrite things rather than try to fix the unfixable. Captain Pike’s “woman on the bridge” line in The Cage is such an example – overt sexism from a character that we’re now very excited to see return. Ligon II and Code of Honor are definitely in the “let’s all just pretend that never happened” category… for the good of the franchise!

It’s amazing, when you think about it, that Code of Honor was produced as late as 1987. It would still feel outdated had it been part of The Original Series in the 1960s, but to know that it was produced for The Next Generation – within my own lifetime – is one of those things that boggles the mind.

A ritual combat arena on the surface of Ligon II.

Code of Honor is an episode that I think Trekkies need to watch. It’s worth remembering that, despite its lofty ambitions and attempts to depict a better future, the people who create Star Trek can still make mistakes. This was an episode that Gene Roddenberry had some creative input in and signed off on – he was The Next Generation’s executive producer at the time.

The episode is noteworthy for its complete lack of awareness. The people who created this story, cast it, and put it to screen were so blind to the offensive stereotypes that it depicted that they allowed it to progress and even get broadcast. Star Trek may have made strides, even in its early years, in its attempts to confront and tackle things like segregation and race hate – but it was blind, at times, to subtler, more covert forms of racism and racial stereotyping.

Planet #4:
Uninhabited Delta Quadrant world

A hyper-evolved human on the surface of this unnamed planet.

This planet doesn’t have a name… but I vote we call it “Tom Paris and Captain Janeway’s sex planet.” That’s right, it’s the planet from Threshold! After crossing the Warp 10 barrier and experiencing hyper-evolution, Tom Paris kidnapped Captain Janeway and took her to this remote, uninhabited world somewhere in the Delta Quadrant. By the time Chakotay and the crew of the USS Voyager tracked them down, both Paris and Janeway had mutated into amphibious salamander-like creatures… and mated.

Although the crew of Voyager successfully recovered Paris and Janeway and the Doctor was able to revert them back to their human forms, for some reason they left their offspring behind. That means somewhere in the Delta Quadrant, little human-salamander offspring are polluting a perfectly innocent planet that was just minding its own business. I’m pretty sure that violates the Prime Directive… in the most disgusting way possible.

This planet now belongs to the human-salamander babies.

As much as some fans (myself included) like to joke about Threshold – which is absolutely one of Voyager’s worst stories – I can’t see Star Trek ever doing anything more with this episode, this concept, or the planet visited in the final few minutes. For completely different reasons to those laid out above, this is another part of Star Trek’s past to simply ignore!

Again, the one exception could be Lower Decks, which has an irreverent take on these things. We saw mating mugatoes in the Season 2 episode Mugato, Gumato, so I wouldn’t put it past the Lower Decks team to dream up a reason to bring back the human-salamanders one day! After all, Tom Paris made an appearance in the show!

Tom Paris in Threshold.

To Threshold’s credit, it won an award for its prosthetic makeup, and while the story was undeniably ridiculous to the point of abject failure, it was at least an attempt to go into a little more detail about Warp Drive and the limits to warp speed. It never sat right with me that Warp 9.9999 was as fast as anyone could ever go… but Warp 10 was supposedly fast enough to travel anywhere in an instant.

However, as with many technobabble things in Star Trek, maybe the complexities of Warp Drive work better when they’re left ambiguous! Ambiguity and vaguery allow for the creative teams to take stories in wildly different directions, allowing for maximum storytelling potential without different writers and different shows being constrained or tripping over one another.

Planet #5:
Romulus

Romulus as it appeared in Nemesis.

What? Too soon?

Romulus was destroyed during the events of 2009’s Star Trek, and we got to learn a little more about this event and its aftermath in Star Trek: Picard Season 1. Though the Romulans survived – well, some of them did, anyway – their homeworld, as well as its sister planet of Remus, is gone. The surviving Romulans are living on a number of other worlds in and around the territory of their former Empire.

The destruction of Romulus was shown in 2009’s Star Trek.

Both Star Trek and Picard Season 1 were somewhat ambiguous on this latter point, though. We don’t know how many Romulans survived, where they went next, or even what became of their Empire. We do know that a faction called the Romulan Free State existed as of 2399, but that the Tal Shiar and Zhat Vash still existed in some form too, and were able to launch military operations on Earth, at the heart of the Federation.

Presumably Romulus’ destruction didn’t kill off either organisation, and the fact that they retained the capability to launch such powerful operations suggests that the Romulan government and its espionage operation still exist in some capacity, presumably having relocated to a different world. To what extent the Romulan Empire remains united is unclear, as is the fate of races like the Remans, who had second-class citizen status.

The Romulan capital city as it appeared in Inter Arma Enim Silent Leges.

With Star Trek: Picard Season 2 going in a different direction, I presume we won’t be in a position to learn much more about the Romulans for a while. But if there are future 24th and 25th Century stories in the years ahead, it would be nice to get some kind of closure; to fully learn what happened to the Romulans in the years and decades after the loss of their homeworld.

By the time of Discovery’s 32nd Century, at least some Romulans had relocated to Vulcan as part of a reunification project. The planet was renamed Ni’Var, and while tensions still existed between the Romulans, Vulcans, and Romulo-Vulcans, it seems that the Romulans got a happy ending of sorts – even if it took centuries to get there!

So that’s it.

The USS Enterprise in orbit of Earth.

There have been plenty of fun and interesting worlds that the Star Trek franchise has visited, with many making just one single appearance. Modern Star Trek has contained a number of references in dialogue or on-screen displays to some of these worlds, giving us tantalising teases about what became of them after we last saw them. Those references are always appreciated!

With over fifty-five years of history and more than 800 episodes at time of writing, it’s inevitable that not all of these planets (and the peoples who populated them) worked well or would be worth going back to. Fortunately it’s relatively uncommon for Star Trek to have made truly egregious missteps, but there are certainly some episodes – and the planets and factions they included – that are best left behind. I hope it was a bit of fun (or at least mildly interesting) to consider a few examples today!
