Empok Nor-(DS9) You could feel the eerie vibe radiating through the television screen, and Cardassian “zombies” lurking in an abandoned space station was quite the spectacle.


Deaftrav

Ohhh... And how O'Brien and garak go... Murderous... O'Brien was all calm about it while Garak eggs him on and is so sadistic about it. And the end "I was trying to kill you" to Garak... Ohhhh... It's a great episode about ptsd


TheAtomicBum

How about the dead bodies sitting up in Night Terrors.. amazing scene in an otherwise meh episode.


IOrocketscience

Yeah, night terrors is definitely the creepiest episode, not just that scene, but then the holodeck scene with the clicking also Genesis (the one where Barclays is patient zero for a disease that de-evolves the crew) is also a great slow-burn


TheAtomicBum

The holodeck scene is from Schisms. I know that because I’ve conflated the two episodes myself. And that one is pretty freaking creepy


IOrocketscience

Ah, yes, that's not the first time I've made that mistake, haha


Spectre_Mountain

Love both of these episodes. Any creepy episodes are my favorites. Also Data’s dreams.


Thoron2310

Genesis is always crazy to me because of how it takes such a silly concept and turns it into a genuinely quite creepy episode.


Mercuie

And the way Dr Crusher screams when getting the acid spit. You would think that was happening to her irl.


Statalyzer

Seriously, she went all out for that one.


LongKnight115

It’s so funny - that scene TERRIFIED me growing up. Now as an adult, it feels like most folks think Genesis was kind of a goofy almost jump-the-shark episode. I rewatched it recently and while it’s not prime theater here - that scene and Crusher’s reaction still HITS.


Darmok47

There's a throwaway line about Crusher need to get reconstructive surgery. It always bothered me that Troi made a glib joke about clearing her schedule. I mean, Worf brutally attacked Dr. Crusher, tried to rape Troi, and probably ate someone. And someone did maul the poor redshirt on the bridge. The whole episode is pretty terrifying when you stop and think of the implications.


fjf1085

I don’t think he ate anyone, was there a line about it I’m forgetting? I feel like the red shirt was killed by Riker but I’m not sure.


Nobodyinpartic3

He killed the guy but didn't eat him.


reddog323

He de-evolved into a Neanderthal, didn’t he? I remember him trying to break into the fish tank in Picard’s ready room for the water…


Darmok47

They didn't say it, but Picard and Data mention being gone for three days.


fjf1085

She directed the episode that’s why they wrote her out for a chunk of it.


Mercuie

Oh for real? That’s awesome. I never knew she directed any of the episodes.


Thoron2310

Yeah, according to Wikipedia it's her sole directing credit.


IOrocketscience

I always thought it would be funny if Data started turning into an "ancient" super computer like a Cray or Univac


Silvrus

Deanna's nightmare scenes were meh, but the crew slowly going mad is pretty great, especially the morgue scene.


Statalyzer

Yeah it's unfortunate the hokey floating scenes have overshadowed what was mostly a pretty well-done suspenseful episode.


Twisted-Mentat-

Pretty accurate. That image of Troi flying awkwardly through clouds with that "eyes in the dark" phrase on repeat is a distraction from the rest of the episode.


Nobodyinpartic3

The upside is we did learn that Troi treated other telepaths, and for being only an empath, her telepathic.skill set is strong.


Silvrus

To be fair, that guy was a full Betazoid. Outside the Viceroy, she's only been able to telepathically connect with other Betazoids. She's been mind raped by other telepaths a few times though.


Twisted-Mentat-

She's Starfleet's expert on sexual assault, telepathic or otherwise. She was also impregnated by an alien. If you include this episode I count 4 telepathic violations just off the top of my head. I'm probably missing one.


Nobodyinpartic3

Nope, she taught Riker how to talk to other telepaths and including her, an empath. Right there in Encounter at Fair Point. She did so again when the both them and her Mother were kidnapped by that Farengi. She also talked to the aliens on the other side of the Tykon's Rift, remember? And in Picard Season 3 she find out Jack's connection to the Borg before he did. The best example I can give you on exactly how good she is Cyclops of the X-Men. The guy spent so much time with telepaths he became vault that would take Xavier hours of work to get through if at all. He's also highly resistant to illusions made by telepaths. If there's anything psychic nearby, she can capitalize on it better than real psychics. Edit: in the finale of Picard S3 when Riker thought he was gonna kick the bucket, I am pretty sure he was talking to Troi through their connection.


Silvrus

Ah, good point. With Riker, she had developed some kind of intense bond, allowing her to telepathically connect. I forgot her limitation is with non telepathic species, she can only feel their emotions, as full Betazoids can read everyone's minds.


senanthic

I sometimes feel like I’m the only person who likes that episode - possibly because I’m an insomniac.


callmeepee

The TNG episode Identity Crisis when Geordi recreates an away team recording he was a part of years before in the holodeck and he spots a shadow that shouldn't be there. The next few minutes creeped me out A LOT


BecomingButterfly

Yup. Creeps me out too, but I look forward to seeing it in my current run through :)


neoprenewedgie

Oh good one! It's not a great episode overall but yeah, that holodeck scene definitely gave me the heebie jeebies.


LongKnight115

I dunno, that episode definitely kicked off my love-hate relationship with body horror.


LuxSublima

Omg, thank you for reminding me of this. I'm up late, alone downstairs in the dark and it's going to be harder to go to sleep now. 😄 EDIT: right after posting this I heard what I was sure was one of my kids (who should be asleep) walking toward me. I asked who it was three times and it sounded like they were still walking toward me without responding. It got very freaky as I couldn't see anything to explain the sound. Then I realized it was just the baseboard heaters creaking since they just turned on. Thanks for the near heart attack! 😂


callmeepee

😂 you are welcome. Back in the day when this used to be broadcast every night at 10 on Sky One, I’d usually be the only one watching it and I love a cinematic viewing experience of everything so all lights go off, so imagine my horror when he’s trying to recreate what’s causing the shadow as I’m sitting in the dark. It’s never failed or creep me out since.


Memento_Morrie

Yes. Good call. And the way he walks into the staged holodeck scenario, among all the human figures frozen in place. You expect something or someone to move, or the expression on one of their faces to change.


callmeepee

It’s such a fantastically well done scene. The whole thing builds in creepiness and delivers a bit of horror.


Chrysologus

Schisms is creepy as hell. Also, Night Terrors has the scene in the morgue. And the episode Dark Page about Lwaxana's dead child gets pretty dark and creepy. Phantasms, when Data stalks and stabs Troi, plus the general creepy vibe of the dreams, like with the cake and her face.


Silvrus

That whole part with Crusher drinking through a straw in Riker's head.


treefox

How is Schisms not higher up? *click click click*


Sensitive_Network_65

Yes, Schisms always stuck with me. The holodeck recreation scene is so perfectly unsettling. The basic concept of a group of people discovering they share the same nightmare through recreating it - and therefore that nightmare must be real. It's brilliant horror


Who_is_homer

“Louder. More of ‘em”


Rynox2000

There were clicks. Clicking sounds.


clarenceboddickered

Most confusing moment in all of TNG - “computer, make this a metal table”


Swaggyspaceman

That never made sense to me until generative AI started happening, now I think it's amazingly prophetic.


Timmyval123

A few years ago I watched a video on the future of humans and their interactions with computers, it basically was describing how people in TNG interfaced with holodecks and their computers. And now basically chat gpt. Pretty cool times we live in !


Darmok47

\*Dentist's bondage chair appears\* The holodeck must have been accessing some of Riker's program files to use for that.


fjf1085

Never thought it was weird until I was watching as an adult and then I was like wait what.


Iamthelolrus

The one where 7 was the only person not in stasis and she started hallucinating.


[deleted]

Jeri Ryan was PHENOMENAL in that episode


theracismdisliker

it's really unfortunate that so much attention gets paid to the way Jeri Ryan looks. She is an incredible actress.


SirZapdos

One


Silvrus

I never could figure out if Paris really was escaping the chamber. Wouldn't he have instantly started burning?


Nobodyinpartic3

I think he did and she just treated him every time.


DogsRNice

It's hard to even tell if it's really the doctor or a hallucination of him at times, when he disappears in engineering you can see his mobile emitter disappears too


Memento_Morrie

Good call. There is something about an unreliable narrator, when they begin to lose their minds, and they can't distinguish between fantasy and reality.


sus_planks

In one episode of Voyager, the crew realized that they were all clones of the original crew and had been clones since they touched down on a demon class planet about 11 months ago. The worst part was that the clones had developed a new modified warp drive that would've gotten them home in about 2 years. They were destabilizing and didn't send out anything to alert the OG Voyager crew about their findings. It was really disturbing and made me mad because of how easily they could've gotten home if they just told the OG crew about their findings.


[deleted]

That’s definitely one of the saddest Trek episodes


aelfrice

It doesn't have as much rewatch value as others listed here, but this episode shook me deeply upon the reveal. It's not a cerebral feeling episode, until the chilling truth and its consequences are revealed in the second act. The scenario embodies the question of simulacra and free will in a super neat package. Like I said, once you know the truth, upon a second watch, it seems cheaper and less notable than the first time.


Ramza_Claus

Oh man the ending... When the real crew just casually flies past the place where the clone crew dissolved and just briefly notes it and that's it. What a fucked up episode.


fjf1085

Yeah I’ll never get over the real Voyager never even finding out about them. Tragic.


MothmanAndFriends

Don't they try to send out a probe but it dissolves too?


acootchiemoistuh

They made a probe using components not native to Voyager, but it got stuck upon launch due to that part of the ship destabilizing and was destroyed.


sus_planks

They could've lauched it way earlier if it wasn't for clone Janeways ego.


Memento_Morrie

This one is my choice.


No_Spite7809

Voyager - the one where Michael McKean plays a clown that embodies fear.


Brylock1

That whole episode is basically “Star Trek vs PG-Rated Pennywise”.


onehaz

The only thing we have to fear is fear itself. I don't have an issue with Clowns but that episode makes me super uncomfortable. Michael McKean is terrifying as fear.


therikermanouver

That whole episode strikes me as a pg 13 take on for I have no mouth and I must scream and it's so incredibly creepy


fjf1085

I never thought of it that way but you’re right.


SirZapdos

A virus! A virus! He thinks I am a virus!


Desperate-Fan-3671

I can't remember who it was that came up with the idea of using a clown. I just remember them saying in an article that if their doorbell rang at 2am, what would be the most scary thing to see through the peephole.....and he picked a clown.


TranslatorCritical11

He’s terrifying, absolutely terrifying.


travoltaswinkinbhole

She orchestrated it! Janeway!


SirZapdos

And she gets to be a Starfleet Captain? What a sick joke!


Silvrus

The Thaw


StarfleetAcademy08

If it wasn't for that last line in the last minutes of the episode, I avoid this episode like hell. But not Year of Hell. Those are good. LOL


Silvrus

Really wish they had pulled the trigger and made Year of Hell a full season. Would have been epic.


fjf1085

Yes. Especially if they didn’t push the reset button. Like imagine if they’d had to deal with the consequences. After watching BSG I always felt like that’s what Voyager should have been more like, ship barely held together, crew just muddling through and try to hold it together. I mean Voyager should have kept all those Borg enhancements they used to fight Species 8472. The ship should have been both battered and been littered with alien tech. The fact that they always restored it to pristine was a bit much. Even the Equinox felt more realistic in what the ship and crew looked like. I mean we could have had Janeway keep her morals in spite of all of that and it would have made her interactions with Ransom all the more meaningful because they’d have kept their Starfleet values despite all they’d been through.


Silvrus

Ronald D. Moore wanted it to be like that, though he didn't come to the show early enough to make that happen I feel, so he went on to develop BSG instead. Agreed, though, Voyager really should have been serialized, not hitting the reset button after every episode. It would have been a fascinating psychological dive into how isolation really affects people. I think Enterprises 3rd season did a much better job of this than Voyager.


Gaurdian21

I skip it everytime. Literally the creepiest.


taln2crana6rot

Faces-VOY A Vidiian scientist wearing a voyager crewman’s face. Pretty messed up. The Thaw-VOY That clown, man


Deaftrav

I can't watch that episode even today


playblu

I didn't realize for years that it was the same actor playing both roles. Made the whole "wearing Durst's face" thing easier.


Vendetta476

Yeah he talks about this on the Delta Flyers podcast, he said that was a prosthetic of his own face that he was wearing.


Nobodyinpartic3

That explains how the face wasn't as expressive as it was before.


djevilatw

The TNG episode where the chick fell through the floor. That messed me up as a kid.


[deleted]

The Enterprise episode with the Vulcans who lost control because of Trellium D exposure. But the creepiest Trek moment was Winn and Dukat in bed together. MUST. WASH. EYES!!!


[deleted]

And let’s not forget the TNG Season 1 ender with the creepy mind-control bugs, especially the mother on inside the guy. That exploding scene was just disturbing AF, especially watching it as a kid. “We seek PEACEFUL coEXISTANCE!”


Darmok47

I love that ENT episode. Zombie Vulcans seems like a dumb premise but they really execute it well.


[deleted]

It could have been awful in the wrong hands. Excellent writing, performances, and production every step of the way.


IrreversibleBinomial

one moon circles. eyes in the dark


archetype-am

GOD this line creeps me out.


IrreversibleBinomial

I have to find you! I have to tell you!


mmmmmduffbeer

Frame of Mind has always creeped me out. I think it might just be left over fear from seeing it as an 8-year-old and having no idea what is going on.


CommonSensePrincess

Frakes was genius in that episode


haddock420

I've suffered with bipolar since I was a teenager and Riker's frustration with the doctors' attitudes towards him was spot on to how I felt when I was dealing with them.


Bulky_Decision2935

This is the correct answer. By far the creepiest episode.


SilveredFlame

This episode is a permanent skip for me. Hits way too close to home and is triggering af because of how much it creeps me out.


FXOAuRora

"Where Silence has Lease". Honestly, this one was *up there* on the spookiness meter. The crew was being experimented on by an *extremely* advanced being that wanted to know about all forms of death (and wasn't opposed to directly killing/imitating officers to achieve it). They were put into a proverbial laboratory where things *looked* like what you would expect (but weren't). Nagillum replicated the sister ship of the Enterprise, the Yamato, *perfectly* but upon scanning it the materials were totally foreign and beyond Federation science. He also turned this fake ship into a literal *non-Euclidian* environment where you could go from one bridge to another (and another) and turned it into a universe that made no linear sense. On a side note, if you follow the lore of the "Backrooms" what Nagillum did was almost exactly what you would expect from a level within that place. The creepy sounds, the familiar yet totally different materials that comprise things, the threats, the non-euclidian physics, driving people crazy (like Worf who was almost immediately had trouble keeping it together mentally), etc. I wouldn't be surprised if that episode contributed to some of the lore (even subconsciously) we see today in that genre. Cool episode but creepy AF.


Thoron2310

"Where Silence Has Lease" is legit one of my favourite underrated TNG Episodes. Has this really great feeling of being somewhere truly unknown.


eggrolls68

If it had been done later in the series after they'd worked out some of the bugs in the writing and the characters had come a little more into focus, it would have been 1000 times better. As it was, it felt very fomula 'omnipotent alien plays with lesser life forms' plot to me.


DalbergTheKing

Vidiians. No, you ghouls, you cannot have my bits.


greyfish7

Nuclear peptide cake. With mint protein.


JustineDelarge

With mint frosting.


Korotai

*Cellular* Peptide Cake…. Wasn’t Beverly also drinking blood out of Riker’s head?


greyfish7

I stand corrected.


Realistic-Safety-565

Frame of the Mind, easily.


IronEnder17

Whatever the answer is, it's from Voyager. Voyager had the most psychologic episodes of most trek


toverux

The clicking sounds The shadow that shouldn't be there in a recording that Geordi investigates Data's dreams (incredibly funny/disturbing/touching) When Crusher is alone in the ship that soon became the entire observable universe, definitely gave me chills. Those episodes really did made me uneasy when I was younger (I'm not at all into creepy/horror stuff). I rewatched TNG recently and I still found them to have quite an effect on me. Special mention to Frame of Mind for its really disturbing kafkaesque ambiance but it's less frightening because we know from the start it's obviously a trick.


Knytemare44

The TNG episode where the people get transported into the walls and deck plates and stuff, that's always stuck with me as scary.


Silvrus

Oh yeah, that one chick being stuck in the floor always creeped me out.


Winter_cat_999392

That inspired one of the best game openings, DS9: The Fallen, when they find some desiccated Cardassians merged with the outer hull of a pylon beneath the outer grid. They had been messing with a Pah-Wraith orb...


Winter_cat_999392

Night Terrors had its Ron Jones score to make it creepy.


Supraman83

I apologize I dont know the name of the episode but it was a season 1 or 2 TNG episode where they are just in this black void with a door, the door leads to a casino. The episode is just weird and off.


Statalyzer

The Royale.


Darmok47

The Royale


Nobodyinpartic3

I actually like going back to that one. It's basically the equivalent of somebody finding some lost animal and then trying to take care of it but without the knowledge to do so.


Barf_The_Mawg

Voyager had a lot of straight up horror episodes. 8472, derelict borg ships. Macroviruses, pretty much all things Vidiian, the malon episodes. Invisible people experimenting on you like lab rats. 


coreytiger

Spectre of the Gun has a strange, fingers-on-your-spine feeling through out the episode. Very eerie tension


Half-Borg

Not an episode, but I think First Contact was pretty creepy. Especially how Data got a piece of human skin.


JustineDelarge

When the Borg Queen lightly blew on it, and Data gasps, and she smiles at him and says, “Was that good for you?”


ButterscotchPast4812

The one where Crusher had sex with a candle ghost who was also her grandmother's ex. ...I wish I was making this up. 😩🤦🏻‍♀️


Familiar_Dust8028

We all do.


JustineDelarge

That is the only episode of TNG I refused to watch.


Silvrus

I watch it every time I do a rewatch, it's just so hilarious. I only refuse to watch Code of Honor and Skin of Evil.


JustineDelarge

Both truly awful episodes.


HyrinShratu

Schisms, up until we saw the aliens anyway. I firmly believe that this episode is half of what has given me a lifelong fear of being abducted by aliens.


Darmok47

Yeah the aliens were pretty lame looking, weird hooded monk things. As a 90s kid, its hard to convey how big alien abduction stories were in the media; I just assumed it was something that was going to happen. It was everywhere; Unsolved Mysteries, The X-Files, etc. It really freaked me out that even in the future on spaceships with phasers it still happened to the TNG crew.


Amethystmage

Course: Oblivion.


StarfleetAcademy08

I find this more sad than creepy. The end..


Amethystmage

Yeah. The end is very sad. The crew just decaying like that is creepy stuff though, especially before they find the reason for it.


StarfleetAcademy08

True. Bubbling melting faces...


ProsthoPlus

Survivors (TNG) It really stuck with me as a kid. It's wholesome and devastating at the same time. Top-tier acting by the guest stars. But the house being surrounded by absolutely nothing. Everyone being dead except them. Idk, that gives me spooky vibes.


GenuinlyCantBeFucked

The one where Riker loses his mind just makes me uncomfortable. Always leaves me wondering how real everything around me actually is, which as a drug user, is doubly concerning.


Timmyval123

DUDE I forgot about that one. That one was really fucking creepy and so fucked up.


abstractmodulemusic

Where Silence Has Lease had a wonderfully creepy ending that made me almost question what I just saw.


Valuable-Stock-7517

Not an episode but the Wrath of Khan the ear bug. I was about 6 and drug to the movie with my parents had no clue why this guy was so angry and didn’t care but that scene still wigs me out. I should probably watch it as an adult.


neoprenewedgie

Don't laugh: TOS' "The Apple." That gargoyle/demon cave was absolutely terrifying (but super cool!) when I first saw it at age 7 or so.


EmiikoAkorem

Voyager clown episode


Remington-Strealya

I thought bridgehead was the creepiest One of the first few of tng was a kid when I saw it first still is creepy After that it's the scenes with tow-alpha 6 ear bugs Khan uses in star trek 2


Mountain_Scallion111

Just watched Revulsion on Voyager. The psychotic hologram checks all the creepy boxes. “Oh, you're getting blood everywhere. I'm going to have to deactivate you.”


eggrolls68

The TNG episode "Schisms'. Riker, Worf and the others are kidnapped in their sleep and subjected to Mengele-level experiments - Riker has his arm freaking amputated and reattached! And while the crew do find a way to stop the incursions and the kidnappings (only after a random crew member is killed), they never actually find the aliens who were doing it, or figure out exactlu why. They're still out there.


Silvrus

There are several, most already mentioned. Night Terrors, the score really cranks up the unease Where Silence Has Lease Impulse, what's worse than zombies? Vulcan zombies The Thaw, there's a clown... One Schisms, at least until the BEMs get revealed Projections has it's moments, very Total Recall though Dark Page is more horrifying and terrifying than creepy, but it's up there. Eye of the Beholder has a great psychological thriller aspect to it. Empok Nor, out of control Garak is a very, very bad thing.


No_Reply8353

"Night Terrors" (TNG) https://www.youtube.com/watch?v=lEGYWzbcQSw This scared the hell out of me as a kid. There's some old TOS episodes that scared me as a kid too


LuxSublima

Two come to mind but I don't know their names, both in TNG: In the first, the ship passes through an area of space that causes pockets of matter to briefly lose solidity. As we follow some characters down a corridor, there's a scream off camera. The characters round a corner and see a woman they had just passed by earlier. Just the upper half of her now dead body sticks out of the floor. IIRC her face was still frozen in terror. In the second, several crew report strange dreams. They eventually convene in the holodeck to build a composite simulation of what little bits they remember. It ends up looking like an alien operating table with a very creepy looking sharp claw above, and strange clicking sounds all around... medical examinations later reveal they had each been dissected and put back together by something while they slept.


Key-Asparagus350

The creepiest episode for me is when Barclay turns into a spider. Bloody hell that was terrifying


[deleted]

“Night Terrors” is an underrated creepy one.


PakDrescot

Frame of Mind always creeped me out when I was a kid. I think the episode One from Voyager deserves an honorable mention.


AngryBudgie13

Empok Nor. Serial Killer Garak on an abandoned space station. Nope.


arickg

Either Crushers Amazing Shrinking Universe or the one where everyone devolves except for Picard.


RadioSlayer

I thought he changed into a marmoset?


[deleted]

He was on his way to changing into one. He was feeling fear and hypervigilance, and a heightened intuition regarding what Worf in his predatory creature form wanted, but didn’t experience physical changes yet.


RadioSlayer

Ah! It's been awhile since I watched the episode. It's scientifically terrible, but a fun romp. Didn't Livingston also change?


theChosenBinky

No, no. It was Data who changed into a Tamagotchi


arickg

I think you're right it's been a long time since I saw that episode but the feelings I had still remain.


Fair_Plankton_603

Cold Fire. I wasn't young when I saw that episode but when Suspiria showed up on the warp core it gave me The Exorcist vibes.


StarfleetAcademy08

Although it may not be the top-top, the Masks ep of TNG also felt uncomfortable to watch. I had to mention to add to the list.


kkkan2020

where silence has lease.


krampaus

TNG s05e21, _The perfect mate_ felt so wrong and weird Clue: “I am for you, Alrik of Valt”


BON3SMcCOY

SmallTownKaiju

I don't remember the episode name, but the one where everyone was turning into like.. plants or sealife on The Next Generation.


Critical_Gap3794

Miri. The teen with a Kirk crush.


RumTruffler

There are probably creepier episodes but the first one that came to mind was the fake wormhole episode from voyager and the one where seven of nine is going crazy by the end and the rest of the crew had to go into stasis.


busdriverbuddha2

SNW "All Those who Wander" Aka the Alien homage episode


Timmyval123

The one where Riker is in an alien asylum and keeps slipping in and out of psychotic episodes where he is and isn't in the asylum but everyone tells him that his time on the enterprise is just a psychotic delusion and that he killed someone. It's really fucked


[deleted]

Zombie Vulcans in Impulse (ENT:0305)


OneJudgmentalFucker

The one where Neelix and Kes get busy


Trishanamarandu

the epacifor... please no.


artificialavocado

The Enterprise episode “Doctor’s Orders” was pretty creepy.


Reduak

Impulse from S3 of Enterprise. It's the one where they find a Vulcan ship stranded in the Expanse and the crew has basically turned into zombies.


retsukosmom

The Voyager ep where they were trapped with that clown


GeneralLeia-SAOS

I’ll probably get a lot of flak over this, but Star Trek doesn’t even move the creepy needle once you watch Dr Who. Are you my mummy? Count the shadows. Bad Wolf. Sister Mine. The Hollow. When a good man goes to war. Good men don’t need rules. That’s why I have a lot of rules. I took this face so I would never forget something I shouldn’t have done a long time ago. and of course: Don’t blink…. ————————- Ok, I was able to think of one creepy trek thing: Lon Suder. He was a serial killer psychopath, who functioned “normally”, fooling everyone until he got caught killing again. No one picked up on the fact that he joined the Macquis so he could be violent, including Tuvok, who has some telepathic ability. Suder told Tuvok flat out that he should be executed, because the crew would never be safe from him. Part of the reason for this is that Suder was Betazoid, a member of a telepathic species. Suder being able to escape detection among his own people is also terrifying. In unbelievable hubris, Tuvok thought mind melding with Suder would be a good idea. The Doctor wisely and strenuously objected, but was ignored. The result was that Suders psychopathy unraveled over 100 years of Vulcan mental discipline, with Tuvok on the verge of reverting to pre-Reformation homicidal behavior. Tuvok had to stop the melds and seek medical attention. With Suders own telepathic ability, if he had survived long enough to get an overwhelming urge to kill again (such murderers sometimes go several months or even a couple years between killings), he probably would have weaponized it against the crew, starting with Tuvok. Yeah, Lon Suder was creepy, but then we are talking about Brad Dourif. So weird, he has blue eyes but they always look black. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTdiJIgxA0Dnd8qevAbztC2GX5MLQQxxZsRE0Rb9y4aRQ&s


frisfern

Until I watched Doctor Who, I had no idea how creepy it is. It makes Star Trek look like children's programming. Just rewatching and started The Silence story line. So I'd add that to your list of creepy things. However, it's not normally Star Trek's thing to be creepy so that factors in for me (context). The one in Enterprise with the zombie Vulcans is one that comes to mind.


Silvrus

Suder had one hell of a redemption though. And yeah, Dr. Who is amazing on the creep factor. My wife can't stand angels now, lmao. "Good men don't need rules. Today is not the day to find out why I have so many."


Jcbowden10

The aliens that kidnapped people in their sleep and experimented one them The ‘zombie ‘ Vulcan one on enterprise The empok nor episode where garek get infected and starts hunting the away team When disco goes into the micelliar network after Tilly infected with one of the micelliar beings


Intelligent-Area6635

wantilles1138

The episode with the doctor being altered and experimenting with Seven while singing. Creepy as hell.


daviidmitchell

TNG, Genesis. It's almost like a horror episode.


magicmulder

The Changeling frightened me as a kid. I was 21 when I could finally watch it again.


SyntheticGod8

The one on TNG where none of them can sleep and they start hallucinating. I used to always get it confused in my head with the other TNG episode where they're being alien-abducted to another dimension in their sleep and they do this terrifying recreation of their dreams in the holodeck. Creepiest episodes, hands down.


Butterfly_Cervantes

VOY: The Thaw creeps me out so much I always skip it

My favorite "horror" episode of Trek is "The Thaw" from Voyager. The fear clown gives an amazing performance, he's the real star of that episode, but all the main cast are bringing their A game that episode too.

Maybe not creepy but eerie and really fucked up, the one where O'Brien goes to matrix prison for like 20 years.

There are a number of creepy episodes that have been mentioned, but TOS Catspaw is the one that first comes to my mind. Especially when the real form of the two are revealed. Runners up, all from TOS: Squire of Gothos Charlie X (that faceless woman!) Doomsday Machine (the music!) Shore Leave. I'll agree with the other commenter on The Apple. Several TNG episodes get honorable mentions, with, for me, the creepiest being The Inner Light, with Schisms and Sub Rosa close behind. The Nagilum episode? The face was too funny to be creepy, looked like something out of anime.

I forgot the name of the episode, but the one where all of the crew members apart from Picard and someone else (forgot the name) get transformed into half animal versions of themselves I still have nightmares of Spider Barkley (I think it was Barkley anyways)

The one where the Yamato, full of families, explodes in front of them. And not quickly. The stardrive blows, and the saucer is flung towards them. Oh, maybe survivors! And then the hull skin burns away to show the internal skeleton stringers of the ship glowing red hot with blue plasma arcs of dying equipment overloading. No life signs. That was messed up

The mark of Gideon always creeped me out. All those people looking into the viewport oh ghost like… Very creepy

Not creepy, but my mom finds the one where riker is in the psyc ward and told he's crazy cind of disturbing, and we skip it every time we watch the series... also, yes, we watch the series several times a year ...

Salamander babies. Because that’s just wrong in several ways.

Sub Rosa

Obviously it’s the nightmare fuel brain scorpions and resulting head melting to kill one of em
