History NightmareFuel / StarTrekEnterprise

* Most of "Strange New World" is creepy, but the worst is when they beam up Crewman Novakovich during a storm and he materializes [[{{Telefrag}} with sticks and debris embedded in his face and body]].
** Trip’s paranoid hatred of T’Pol (who is the only one not hallucinating and thus, not believed when she says there’s nothing) gets to terrifying levels, especially when he’s violent with her.
* The StarfishAliens in "Silent Enemy", pictured above. They come out of nowhere, [[TheVoiceless say nothing]], and are [[InscrutableAliens extremely unpredictable in how they act]]. They're also shown to be capable of [[CurbStompBattle effortlessly crippling and toying with Enterprise]]. When they actually board ''Enterprise'', we get to see them... And [[MushroomMan you'll wish]] [[BizarreAlienBiology you]] [[NightmareFace hadn't]]. One shudders to think what would've happened if they had [[FridgeHorror managed to capture the Enterprise crew...]]

** After the above encounter, ''Enterprise'' [[HopeSpot tests its new phase cannons]] on a nearby asteroid... only to suffer from ExplosiveOverclocking due to sabotage. The aliens ''knew'' they were building those cannons and wanted to taunt them with the knowledge it wasn't going to work!

** Their taunting message made from an edited version of Archer's own speech, showing whatever they are, they know damn well what they're doing.

* In "Fusion," we get one of the emotional Vulcans, Tolaris, and his MindMeld with T'Pol that quickly turns into a MindRape. She very plainly tells him to stop, [[MoralEventHorizon and he refuses]]. It's viscerally unpleasant to watch. ("Stigma" makes it worse with TheReveal that he infected her with the equivalent of an STD, like being raped and coming down with AIDS as a result.)

* "Shockwave, Part 2." T'Pol undergoes ColdBloodedTorture at the hands of Silik. Seeing the normally-composed Vulcan shivering and barely coherent is troubling.

* The automated repair station in "Dead Stop" that turned out to kidnap crewmembers and fake their deaths so it could [[PoweredByAForsakenChild use their brains in its computers]]. Archer blows it up in the end...but the final scene shows it beginning to put itself back together.
** Even more terrifying, in a [[FreezeFrameBonus blink-and-you'll-miss-it moment]], one of the species that is seen hooked up to the central computer is a Vaadwaur, a species from the ''Delta'' Quadrant that, according to ''Series/StarTrekVoyager'', went into prolonged hibernation in the 15th century following a war with the Turei and didn't wake until the 24th century. How did a Vaadwaur get aboard the automated repair station in the first place?!
* "Singularity" seems like a "Naked Time"-ish episode, where everyone is obsessed with tiny tasks and becomes extremely agitated. T'Pol is unaffected, so she goes to check if Phlox is also all right. He isn't. He has become so obsessed with Mayweather's headache that he's going to vivisect his brain, seeming ''identical'' to the MirrorUniverse Phlox, and threatens to kill T'Pol for getting in the way of his experiments.
* In "Stigma," in addition to what T'Pol's already going through after the events of "Fusion," the Vulcan doctors apparently think nothing of running tests on her without her knowledge or consent using a DNA sample they tricked her into giving. Her right to privacy seems to bear no weight at all, purely because Dr Phlox's questions made them ''suspect'' she has a particular illness. Which all raises serious questions about patient rights in Vulcan society.
* "Regeneration" presents a pair of Borg that are less formidable than in previous appearances, yet manages the feat of making them considerably ''scarier'' than they had been in quite some time. They almost reach a kind of VillainousValor as they attempt to make their escape, infecting anyone they can with nanoprobes (whose effect on Phlox is NightmareFuel all by itself) and cleverly disrupting ''Enterprise'''s systems in order to buy enough time for them to modify their obviously-inferior ship enough to pose a threat.
** What really makes the episode work is following the scientists for the first act as they investigate the Borg debris. It plays entirely like a horror movie, where the audience knows that the monster is coming and the characters are completely unaware. When one of them remarks that the unknown aliens could be entirely friendly with earnestness, the audience knows better, and every second something doesn't happen ramps up the tension for when it finally does.
** "Regeneration" works beautifully as an example of a perfect circle, acting at once as a {{sequel}} and a {{prequel}} not only to ''[[Film/StarTrekFirstContact First Contact]]'', but TNG's "Q, Who?" where the Borg signal penetrates deep into the Delta Quadrant. It begs an interesting question: Did Q simply drop the ''Enterprise''-D into Borg-controlled space, or did the ''Enterprise''-D meet a Borg cube that was ''already on its way to assimilate humanity''?

* "Impulse" has a crew of Vulcans who have all gone insane, and T'Pol isn't getting much better, [[SanitySlippage getting more and more unhinged]] throughout the episode and even pulling a phase pistol on Archer. They manage to get her back to ''Enterprise'' and she's expected to make a full recovery, but she sees the dead Vulcans on the ship. One attacks her in the turbolift. And then she wakes up and '''ONE IS STANDING RIGHT OVER HER''' before she wakes up again. That last minute does a good job of making it clear that she'll recover, but it won't be a fun couple of days. Making it worse is the fact she never fully recovers, as her ensuing trillium addiction demonstrates.
* "Exile." Think SerialKiller drama combined with ''WesternAnimation/BeautyAndTheBeast''. First, Tarquin tries to entice Hoshi with a form he thinks will be attractive to her...while whispering in her skull, making her hallucinate him on all the viewscreens in the command center, and generally causing her to think that she's losing her mind (again). When he does make contact, he makes her stay in his house in exchange for his help and demonstrates that he's been rifling through her memories to the smallest detail (never once asking her permission to do this, even her more painful memories) and tries using them to convince her to stay. When that fails and she finds the graves of his previous "companions," he creates an illusion of Archer essentially ordering her to stay and then attacks ''Enterprise'' itself. She has to threaten to break his telepathy amplifier to make him let her go. FreudianExcuse or not, that is some major-league creepiness.
* In "Doctor's Orders," Phlox experiences hallucinations whilst he and T'Pol are the only members of the crew awake for a trip through radiation that is dangerous to humans, including a horrifically disfigured Hoshi and Xindi-Insectoids prowling the ''Enterprise'''s corridors. At the end, it's revealed that Phlox was hallucinating T'Pol as well. She was really sleeping along with the rest of the crew.
* The above two examples, Phlox's decision to support what is essentially genocide-by-inaction in "Dear Doctor" and his MirrorUniverse counterpart being one of the ''least'' radically different in terms of personality, has lead more than one viewer [[AlternateCharacterInterpretation to suggest]] that Phlox is actually a [[MadScientist dangerous nut]] seconds away from [[JumpingOffTheSlipperySlope cracking]] and going on a killing spree!

* Worst of all, though, is the ''much'' more graphic portrayal of what happens to victims of ExplosiveInstrumentation when the NX-01 gets attacked. Other ''Trek'' shows and movies have the StarTrekShake and the occasional sooty HesDeadJim person; ''Enterprise'' has things like [[ManOnFire people on fire]] and screaming, or [[ThrownOutTheAirlock crewmen blown out into space when the hull is breached]], twitching for a bit, and then stopping.
** The specific examples mentioned just above are shown in "Azati Prime" when the Xindi blast ''Enterprise'' into a floating wreck, perfectly demonstrating just [[DarkestHour how bleak things have become for our heroes]] in their search for the Xindi superweapon.

* "Storm Front": ThoseWackyNazis are ''winning'' UsefulNotes/WorldWarII. From [[DayOfTheJackboot the sight of the White House draped in swastikas]] to a newsreel of UsefulNotes/AdolfHitler in New York...''brrr''.

* "Cold Station 12" shows a man being subjected to ColdBloodedTorture via Symbalene blood burn. Between the BloodFromEveryOrifice and the agonized pleading for release, even Dr. Soong (who is allowing it to happen) is [[EvenEvilHasStandards disturbed by his suffering]].
* "In a Mirror, Darkly" takes the agony booth and shows what prolonged exposure can do to a person. Mirror!Archer is apparently insane after ten hours in Mirror!Reed's invention; it's just that the culture of that particular universe is so toxic nobody can tell, and even if anyone '''can''' tell, they dare not say so aloud; with Forrest dead, ''he's'' now captain.
* Trip and Hoshi's faces when they are sick in "Observer Effect." So was the possibility of them dying, and the non-physical aliens, but the biggest scare provider was ''Hoshi'' of all people. She was delusional, made speaking in foreign languages seem scary, ''threw up'' at one point, making it worse because Trip was also sick but he didn't throw up, and once mentioned that she ''broke somebody's arm''.

* "Regeneration" presents a trio of Borg that are less formidable than in previous appearances, yet manages the feat of making them considerably ''scarier'' than they had been in quite some time. They almost reach a kind of VillainousValor as they attempt to make their escape, infecting anyone they can with nanoprobes (whose effect on Phlox is NightmareFuel all by itself) and cleverly disrupting ''Enterprise'''s systems in order to buy enough time for them to modify their obviously-inferior ship enough to pose a threat.

* In "Doctor's Orders," Phlox experiences hallucinations whilst he and T'Pol are the only members of the crew awake for a trip through radiation that is dangerous to humans, including a horrifically disfigured Hoshi and Xindi-Insectoids prowling the ''Enterprise''s corridors.

--> '''T'Pol:''' ...the science Vulcan directorate has determined that time travel is...not fair.
* The Xindi-[[BugWar Insectoids]] are enormous [[SerkisFolk computer-animated]] ants. Industrial Light and Magic gives us all the detail on them you'll ever want and then some.

** Meanwhile, the novels, in their own separate cannon, make them slightly less unpleasant, but still creepy: There, they're called the Verians, and because they developed on a planet far from its star, they see and communicate very differently. From their point of view, they're experimenting on animals. All that fighting back? Basically a lion trying to claw your face off when you've upset it, not a sentient being trying to defend itself.

One shudders to think what would've happened if they had [[FridgeHorror managed to capture the Enterprise crew...]][[labelnote:Expanded Universe]]We indeed get to see what would've likely happened in ''VideoGame/StarTrekOnline'': These aliens, called the Elachi, reproduce by [[FaceFullofAlienWingWong infesting prisoners]] with [[FesteringFungus spores]], which proceed to [[CruelAndUnusualDeath consume the victim entirely (and slowly)]] and then use the accrued mass to merge into a new Elachi, a process that makes [[TheAssimilator Borg]] assimilation seem pleasant by comparison.[[/labelnote]]
