History NightmareFuel / TheFlash2014

* Eobard stabs Simon Stagg and holds the knife in him when he tries to withdraw. His motive for doing this? [[PoisonousFriend "The Flash must be kept safe."]]

* For some AdultFear, Joe being helpless to watch as Clock King drags Iris away. This man has already proven himself to be a clearly unhinged gunman and now he has your daughter!

* The moment when Weather Wizard puts his hand on Joe's broken leg and Joe cries out in pain. It's horrible to witness a beloved character in such pain, and then Weather Wizard says it could be worse--when he survived the plane crash, [[AdultFear he broke nearly every bone in his body]].

* Imagine looking on helplessly at your adopted child of a different race as doctors try to restart the kid's heart to no avail. Suddenly, the person whose catastrophic scientific failure put the kid in the hospital to begin with, someone who you've never spoken to before in your life, suddenly comes rolling in wearing a devious-looking smile. They talk about how they know what's going in the kid's body and only they have the tools to save the kid, and despite the fact they've never spoken to you before and thus shouldn't know you from a hole in the wall, they even actively call you and the kid by name and address the kid as your child without you ever telling them this. All the while you're looking between this person and the emergency room and you see just how futile the doctors' attempts to save your kid really are. [[ParanoiaFuel You're now faced with knowing that your only hope to save the kid's life is to turn them over to this person who you already every reason in the world not to trust]] [[AdultFear and hope that this person is both truly willing and somehow able to carry out their promise]]. This was Joe West's experience when he was approached by Eobard Thawne with a comatose Barry Allen's life on the line. [[ProperlyParanoid NO WONDER he never trusted him.]]

* Some major AdultFear for Earth-2 Wells; first, he hears about a metahuman attack at his daughter's college, then he tries to call her, only to see [[OhCrap her phone in the rubble]] on the news. The fact that it's [[TheDreaded Zoom]] holding his daughter hostage is even more horrifying.

* The AdultFear of the Trickster, dressed as Santa, giving children all over the city bombs disguised as presents.

* Harry's monologue/journal entry about [[AdultFear losing Jesse]] at the planetarium, and how this experience awoke some sort of dark instinct within him, an instinct that told him that with absolute certainty, he would do ''anything'' to get her back all the while we watch him perform a lobotomy on Turtle.

* AdultFear for Barry -- when he and Nora manage to get the device that allowed Zoom to obtain Barry's speed, Zoom returns and then notices ''Nora'' and now wants to take his daughter's speed. And after they managed to get away from him, Zoom still goes after the both of them with the intent of gaining their speed. A Time Wraith manages to stop this, but who knows what the hell Zoom was going to do to the both of them if he eventually caught up with them, which he ''nearly'' did.

* AdultFear again for Barry and Iris: Being forced to watch as the BigBad ''breaks your daughters back!'' right in front of you.

** His CreepyMonotone and ruthlessly logical calculation abilities mean that he's basically turned into ''DeVoe.''

* Eva confirms that Kamilla and Singh are alive. Not that it's fully recomforting, since they are still in a mind damaging dimension.

* Despite the name, Prism is an utter nightmare. All he has to do is look at you and bam! You're evil now! A woman even goes so far as to try and shoot an innocent man. When the effect wears off, her near MyGodWhatHaveIDone reaction is horrifying.
** Because he's normally so nice, when Barry is affected by Bivolo's rage power, his anger is frightening by contrast, from lashing out at his friends to attacking Eddie (who has no idea who he is or why he's being attacked), to completely ignoring Iris and Oliver's attempts to talk him down.

* Vandal Savage is both deadly and very quick to kill, having had thousands of years of practice. His mystical nature is enough to make Barry decide Team Flash needs help, and in one timeline he's able to kill Team Arrow, Kendra and Carter with a magic staff.
* For Kendra, Vandal is a very potent source of nightmare fuel: this is a man who can ''not'' take no for an answer who is willing to follow her to the ends of the Earth and brutally murder her and any one else who gets in his way due to his lust-fueled obsession with her. And unlike most creeps or stalkers, he's ''immortal'', and even death won't save her since he'll just repeat the process with any future reincarnations of her, like he's done over two hundred times already.

* TheReveal that Flashpoint is ''way'' worse than anyone realized. Barry's meddling with time didn't just alter the present, it caused an impact that will be felt 40 years in the future, which is what his message to Rip Hunter was about.
* The Dominators. They look more like [[TheFaceless Slenderman]] than anything else; a single scout ship killed "hundreds" of soldiers in the 50s and almost took out the heroes. They're also frighteningly well-organized, setting up several ambushes within hours of touching down.
** Worse still, ''they exist in other universes''. They came to Krypton, killing and performing experiments before either leaving or being driven off.
*** Maybe in her universe they WERE driven off. After all, the Kryptonians had to have a reason to invent Medusa to only affect non-Kryptonians.

Everything about the whole scene where Barry describes his mother's death to Thawne is ''chilling'' if you go back and watch it after the reveal that Thawne killed Barry's mother.

* The DeletedScene of Cicada is frgihtening because of his VaderBreath.

[[/folder]]

* Wade Eiling's fate. The Reverse-Flash abducts Eiling and takes him to the Central City sewers. There, he unmasks himself and hands him over to a telepathic Grodd, who drags Eiling away. This is horrifying in two ways: it shows how far Wells is willing to go for those he cares for, and that he knows what happened to Grodd and they appear to be ''partners''.

* Nora '''''snaps''''' when she realizes that Barry didn't come with Iris and thus hasn't regretted his decision to exile her -- it's what gives her the push to access the Negative Speed Force: her best friend dying before her eyes, her complicated relationship with Iris and finally her father rejecting her are all laid out before her and a lifetime's worth of anger and resentment comes out. When she gets back to 2019 she's sporting [[[[RedEyesTakeWarning Red]] GlowingEyesOfDoom just like the Reverse-Flash.

[[folder: Episode 16: Failure in as Orphan]]
* Just as Dr. Ambres is stitching up Orlin, the power goes off and S.T.A.R. Labs is attacked by a hooded figure -- Cicada. Except it's not Orlin -- it's Grace .... from the future. She's just as dangerous as she was in Grace's mind, except she's a real person and she's come to Central City to continue her uncle's work.
