History NightmareFuel / The100

* You know the Grounders, those tough, ruthless warriors who view charging the 100 in their fortified position as a challenge worth taking? Who view the fact the 100 have automatic weapons as a minor hurdle to Victory. Stealthy, quick, strong and relentless? Meet the [[{{AlwaysABiggerFish}} Reapers, who view Grounders as walking meals.]] And who when even if their is a hint of them in the area , will cause the [[{{OhCrap}} Grounders to run for their lives, dignity be damned.]] The fact that they are animalistic, brutal and like their meat fresh may have something to do with it.

* The acid fog in "Earth Kills": A storm of toxic fog that viciously burns anyone exposed to it. It leaves [[spoiler: Atom]] in such unimaginable pain that he begs to be killed.

* Bellamy's vision of [[spoiler: Jaha and every single member of the Ark who was killed because he destroyed Raven's radio haunting him and calling him a murderer. The blood spilling out of Jaha's chest makes it all that much more terrifying.]]

* At the end of "We Are Grounders, Part Two", we finally get a look at the "mountain men" that The Grounders dread so much. [[spoiler: Men in sealed suits, wearing gas-masks, with knockout gas grenades and rifles with laser-sights. They capture The 100 and hold them prisoner inside Mount Weather.]] The fact that they appear to have treated the 100's wounds mitigates this slightly, but they're still scary as hell.

* Clarke herself in the first episode of season 2. [[spoiler:She holds one person hostage by the throat, cutting into it, and then tries to escape by opening a hatch, knowing that the radiation will kill them. Note that she doesn't have much reason to doubt their words, but her time outside had left her so paranoid that she kept trying to run.]]

** Jaha found a baby locked in a dresser of the Ark. [[spoiler: He's having a HelpfulHallucination of his son Wells.]]
** Raven needs surgery or runs the risk of never walking again. Unfortunately they don't have any equipment or way to numb the pain means its a MeatgrinderSurgery. ''Her screams echo around the camp the entire time.'' [[spoiler:And even with the surgery she's still crippled enough to need crutches.]]

** The secret behind Mount Weather's medical treatment? [[spoiler:They capture Grounders, harvest their blood, and then drop the corpses into the tunnels where the Reapers can get them. Worse, some of them are ''still alive'' when the Reapers get to them.]]

* Clarke spends the entire episode after she [[spoiler:kills Finn hallucinating him, but the worst time is the first. She's looking at his dead body when his eyes ''snap open'' and he stares at her as he is carried away by the Grounders.]]

* Anything to do with the [[spoiler:marrow transplants conducted by Doctor Tsing]] can be pretty terrifying. [[spoiler:Seeing some of the scars on one of the survivors and seeing the blood-soaked wrappings covering bodies of the deceased is absolutely revolting, especially considering the implication that the victim is alive and conscious throughout the process. In addition to their Grounder farming and the Reaper training, it's made pretty clear that Mount Weather is perpetrating some serious MedicalHorror to achieve their goals.]]
** It was worse in Second Season Finale. [[spoiler:We see them going through the remaining kids one-by-one without remorse, leaving corpses behind despite them screaming for the pain to stop.]]
** Especially because this is usually accompanied by a close-up shot of [[spoiler: the drill boring into the flesh.]] Being ''stabbed'' would be bad enough. Having the knife ''twisted'' would be worse. But having a [[spoiler: piece of metal whirring through your flesh into your bone, so they can kill you piece by piece?]]
* [[spoiler: Dr Tsing dying of radiation poisoning in the corner of an elevator, cornered by Jasper and his friends.]] Yes, it was incredibly cathartic, not to mention [[KarmicDeath deserved]], but still...

* The last moments of Season 2 [[spoiler: Murphy finds a video recording of a man claiming it was his fault that she got the launch codes before shooting himself in the head. Then Jaha finds a women in a red dress in the mansion who is a projection created by a AI which thanks him for his gift. Jaha enters the next room and finds the missile he used to get to earth with the AI calmly stating they have work to do]]

* [[spoiler:Murphy going crazy from the isolation of being sealed in the bunker for over 80 days is nothing short of disturbing.]]
* We actually do see the City of Light... [[spoiler: It's a drug-induced hallucination, leaving Jaha and two Grounders he "recruited" in an eerily relaxed state. The AI from the end of season two, Alie, even speaks to Jaha through the hallucination, asking him to bring "his people" to the city. Murphy was right for not buying into it.]]
** How quick [[spoiler: Otan was ready to kill Emori, his own ''sister'', after a single trip to the City of Light speaks volumes about how powerful A.L.I.E's control over her recruits is.]]
* [[spoiler: Gina gets brutally murdered by an Ice Nation warrior, stabbed multiple times in the stomach. It only gets worse from there: The warrior activates Mount Weather's self-destruct sequence, killing all the Farm Nation survivors inside. Gina doesn't even die right away - she dies slowly, weeping, trying in vain to hang on long enough for Raven to call back with the deactivation code.]]
* [[spoiler: Emerson survived after the irradiation of Mount Weather... And is now working with the Ice Nation.]]
* Charles Pike is about to start a war [[spoiler:against the combined might of the Twelve Clans. He's basically signed Arkadia's death warrant, since even with guns and ammo, the Clans can still overwhelm Arkadia with [[WeHaveReserves their much larger numbers]].]]

* Jaha reveals just how the City of Light tablets remove people's pain: [[spoiler:they rewrite people's brains so any physical or mental pain simply has no way to get in. And just how bad this can be is shown immediately afterwards when Abby asks if he would let his long dead son take them, and Jaha responds like he's never heard the name before.]]
* The flashbacks revealing how the world ended as it did: [[spoiler: Becca informed by aide Chris that Alie has gotten loose and hacking defense systems. Remembering Alie's words of "too many people," Becca tells Chris to send out the killer virus to wipe out Alie only for Chris to choke out that "I did that 10 minutes ago" and it's not working. He goes to shelter as Becca is informed of massive nuclear launches and looks down from the space station to watch as her creation destroys humanity.]]
* ALIE shows just how thin her conception of free will actually is [[spoiler:when she utterly breaks Raven by repeatedly torturing her with the memories of losing Finn, her surgery with no anesthetic, and being drilled into for her bone marrow at Mount Weather.]]
** And how this changes [[spoiler:Raven.]] She's just... gone. And instead, ALIE is puppeting her body. [[spoiler: Lindsey Morgan (Raven)]] perfectly imitating ALIE's body language, with Creator/EricaCerra's (ALIE's) voice coming from her body, is complete uncanny valley nightmare fuel. This while ALIE makes [[spoiler:Raven]] slit her own wrists to force [[spoiler:Abby]] to take the City of Light pill. Her behavior when tied up at Nylah's house is especially creepy, in a distinctly exorcist sort of way.

* In the season 3 finale, we finally learn why ALIE has done what she's done. She's not attempting to control humanity or start another war, [[spoiler:she's giving humanity a MercyKill. The nuclear power plants that she hit in the first nuclear war have begun to melt down, and within six months the Earth will become uninhabitable due to the radiation. At least seven are already burning. And with ALIE gone, there might be no way to stop it.]]

* Season 4 introduces the black rain, which burns on contact. Lengthy exposure results in radiation poisoning and death. [[spoiler: Roan's]] death via black rain is particularly horrific, as he had previously been [[spoiler: beating Luna, but since she is a Nightblood and is immune to the rain, he is ultimately taken down by nature. She finishes him off by drowning him in the poison rain ''which is simultaneously burning his skin and poisoning his lungs.'']] Not a fun way to go.

* In what Wonkru called the "Dark Year," those who were waiting out Praimfiya in the bunker had to [[spoiler: resort to ''cannibalism'']] in order to survive after a food shortage.
** Not only that, but one Grounder was forced by Octavia to [[spoiler: eat his own brother]] at ''gunpoint''.

* [[spoiler: Clarke's 'death']]. She is paralyzed and unable to do anything but watch as Russell thanks her for her (completely unwilling) sacrifice and plunges a needle into her neck.

** And how this changes [[spoiler:Raven.]] She's just... gone. And instead, ALIE is puppeting her body. [[spoiler: Lindsey Morgan (Raven)]] perfectly imitating ALIE's body language, with Erica Cerra's (ALIE's) voice coming from her body, is complete uncanny valley nightmare fuel. This while ALIE makes [[spoiler:Raven]] slit her own wrists to force [[spoiler:Abby]] to take the City of Light pill. Her behavior when tied up at Nylah's house is especially creepy, in a distinctly exorcist sort of way.
