History NightmareFuel / MyLittlePonyFriendshipIsMagicIDW

* Big Mac almost drowing when heavy rain causes the lake waters to swell up and engulf him.

* Even worse in issue #3 where Chrysalis and her minions utterly take over a village of [[TastesLikeDiabetes adorable, innocent cat-like creatures]] filled with WUB- errr love and ''[[http://derpibooru.org/209622 consume them!]]'' Remember: this is what they wanted to do to Equestria!
* [[EmotionEater Queen Chrysalis]] herself is a lot more frightening in the comic book version. Her looks [[{{Pun}} can especially kill]]. Particularly, her first appearances in Issues 1 and 2 are utter Nightmare Fuel showing off her demonic side (especially as Issue 2 has her angrily glaring with her teeth bared), although the rest of her expressions tend to be more comical. As of Issue 4, it's even implied that she's willing to '''consume''' the CMC regardless and things get a lot more scary as the story goes on. Even the covers featuring her of issue #4 is more frightening. [[ArsonMurderAndJaywalking And all of that drool and vampire teeth too!]].
* In issue #3, Chrysalis takes one of the left over kittens and in the next panel, all you can see is a white background splattered by black and the Cutie Mark Crusaders' screams, the implication being that she '''mauled it to death in front of them'''. See the page image at your own risk.
* The cover of issue #3, featuring the Mane Six minus Twilight as Changelings. Also the cover of issue #4, with the Mane Six trapped in Changeling goo as a giant Chrysalis in the background bares her fangs.

* The fact that, not only did the elements of Harmony not work on Accord, they worked in his favor and made him spread his mind control even further! He even got the rest of the mane six, Spike and Princess Celestia! If it wasn't for Starlight, he would've succeeded in his plan.

* Not all of Discord's rampage was done by Discord. There's another draconequus, Cosmos, and unlike Discord she's the spirit of MALICE. She's far more violent than Discord, finding the idea of setting an orphanage of fire to be a good time. Her cruelty is so bad that Discord is actively terrified of her, wanting to do nothing more than run away from her. She was beaten and her power sealed away in six crystal stars... which eventually find their way into the hooves of Celestia, Luna, Twilight, Zecora, Big Macintosh, and Cadance (in that order), all of the normally benevolent characters getting overwhelmed by Cosmos's personality, showing Cosmos's short temper and cruelty before merging into a terrifying fusion of her six hosts and Cosmos herself. She runs roughshod over everyone, at one point morphing into a horrific amalgam of all major villains from the series, before Discord manages to overcome his fear of her and fight back, giving the ponies a chance to defeat her, Spike devouring her power crystals and leaving her helpless, Discord trapping Cosmos on the moon. Beaten she may be, Cosmos left her mark as one of the most terrifying villains in My Little Pony history.

* Even worse in issue #3 where Chrysalis and her minions utterly take over a village of [[TastesLikeDiabetes adorable, innocent cat-like creatures filled with WUB- errr love and ''[[http://derpibooru.org/209622 consume them!]]'' Remember: this is what they wanted to do to Equestria!]]

* [[spoiler:NIGHTMARE RARITY.]] Especially after it's revealed she can control dreams and nightmares.
* The whole arc has some really dark imagery. When [[spoiler:Nightmare Rarity]] is trying to [[WeCanRuleTogether persuade Spike to join her]], she gives him a scepter and tries to place a crown upon his head. When he snaps out of the dream, it turns out the "scepter" is actually a broken stick. The "crown" is even more unsettling: it's a really creepy-looking mess covered in dust and cobwebs with a chain hanging off its side, emblematic of what Nightmare Moon II was about to do to Spike.

* Celestia disappears one day, with even her sister uncertain of what happened to her after seeing her vanish through a magic mirror. [[spoiler: At the end of the first issue in the arc, Celestia re-emerges from the mirror, battered and bruised, ultimately collapsing into her horrified sister's embrace...]] ''[[spoiler: [[OhCrap and the shadowy figure of King Sombra is shown in the mirror's reflection...!]] ]]''
** Worse? [[spoiler:It wasn't Sombra's fault, ''that'' Sombra is a ''good guy''. It was actually done by Mirror!Celestia and Luna.]]

** [[HarsherInHindsight Taken to a whole new level when back in the Season 4 finale]], [[spoiler:Tirek absorbs everyone's magic except the princesses'. When Twilight goes to face him, the sky is the same sort of red as Mirror-Equestria, showing just how close the nation was bought to the same level of ruin.]]
** UpToEleven with the Season 5 finale. [[spoiler: With Starlight undoing the Sonic Rainboom, we see several bad futures of villains winning. From the eternal night of Nightmare Moon to the ruins by Tirek, or even the [[NothingIsScarier horrific unexplainable wasteland]] near the end, it is truly frightening just how much is at stake each time our beloved protagonists fight.]]

* [[spoiler: AU!Sombra's]] FaceHeelTurn is brought about by an obviously very painful transformation thanks to the Elements of Harmony.

* [[spoiler:Radiant Hope]] JumpingOffTheSlipperySlope with [[spoiler:her]] plan to [[spoiler:bring King Sombra back]]. A dark {{Deconstruction}} of [[spoiler:ThePowerOfFriendship]] if ever there was one.
* And speaking of [[spoiler:Sombra]], [[spoiler:his]] LivingShadow NightmareFace just before [[spoiler:Hope revives him]] practically screams ThePowerOfHate.
* Sombra [[spoiler:turning Celestia and Luna to stone]] with minimal effort, abruptly subverting their BigDamnHeroes HopeSpot and effectively putting them on the receiving end of [[spoiler:the way they defeated Discord]].
* TheReveal of [[spoiler:the Umbrum's true identities -- ''not'' the pixie-like beings that Hope has grown accustomed to over the centuries, but {{Shinigami}}-like {{Eldritch Abomination}}s that wouldn't look out-of-place in something like ''Manga/AttackOnTitan'' or ''Manga/{{Bleach}}''.]]
** Not only that, but the sheer MoodWhiplash as soon as [[spoiler:Cadance uses her magic and inadvertently reveals them. Up until then, they're nothing but friendly (or even AffablyEvil, provided that you shared Chrysalis's suspicions all along).]]
** Furthermore, the fact that [[spoiler:Hope lived with these things for over a millennium. Imagine your best friends, neighbors, etc. turning out to be EvilAllAlong and cruelly shattering your entire worldview in an instant.]]

* In Issue #39, [[spoiler:after Diamond Tiara and Apple Bloom are saved,]] the foals become trapped by a thunderstorm which starts washing away the ledge where they are standing.

* The very hot spring that [[TheCorrupter corrupts the Mane 6]]. You could just be stumbling along it one day and decide, "hey, I could totally take a dip in this", and then wake up the next morning doing horrible things to those around you. In fact, that's ''exactly'' what happens! Oh, and it makes you able to resist the powers of a PhysicalGod! Seriously, imagine how much of a threat Applejack would be if she didn't KnowWhenToFoldEm.
** Even worse, it's implied that the Mane 6 [[AndIMustScream were fully aware and in absolutely no control of their actions]]. As soon as they come to, [[MyGodWhatHaveIDone they immediately regret their actions and remember everything they did]]. Bonus points for Rarity, who already suffered this kind of fate less than 40 issues ago, and [[spoiler:Luna, who has to deal with becoming [[StarterVillain Nightmare Moon]], an event so traumatic for her that [[Recap/MyLittlePonyFriendshipIsMagicS5E13DoPrincessesDreamOfMagicSheep she felt the need to psychologically torture herself]], ''again''.]]

** She also creates water balloons filled with the tainted water, which can turn anypony hit with it evil a lot faster than the spring in its natural state, resulting in [[spoiler:the rebirth of Nightmare Moon]], if only for a little while.
** On that subject, [[spoiler:Nightmare Moon]] does quite a number on Pinkie Pie. Any more, and there wouldn't even be a party after the threat is taken care of...

* Corrupted Fluttershy, basically the pony equivalent of ComicBook/PoisonIvy, shows just what could happen if [[HeartIsAnAwesomePower the talent of taking care of animals was taken full advantage of]]; [[WouldHurtAChild she even sics them on the Cutie Mark Crusaders]]! And by the time of the final issue of the arc, the animals are about to go to '''war'''.

** Combining the Pinkie Pie entry with this one, if [[spoiler:Nightmare Moon]] actually offed Pinkie Pie, [[FridgeHorror the chain of events that leads to the other ponies getting cured wouldn't have happened]]. Even if it somehow did, Twilight would be impervious to any and all other plans. If there was no more Pinkie Pie, [[TheBadGuyWins nothing would stand in her way]].

* Corrupted Twilight Sparkle gets it the worst, so much so that the Crusaders and Spike declare her the most immediate threat. She declares herself Empress of Ponyville, is obsessed with intelligence to the point where she drains it out of other ponies (except [[DumbMuscle Bulk Biceps]]), is more than capable of overpowering Rarity and [[DidYouJustPunchOutCthulhu Luna]], and is CrazyPrepared to the T! Many fanfics declared that a [[FaceHeelTurn face-turned]] Twilight Sparkle would be one of the worst threats Equestria would know, and this comic proves them all right; the only thing that did her in was ''[[NoNonsenseVillain her own lack of a sense of humor]]''.

* [[VileVillainSaccharineShow Almost everything the Changelings do]]. When they're not acting like the aliens from InvasionOfTheBodySnatchers, they're acting like just-this-side-of-kid-friendly [[Film/TheThing1982 Things]]. "Infected" indeed.

* Everyone in Ponyville is being mind controlled by the villain of the story and now they are tearing apart a dam to flood their own town. Worst of all, the Mane Six are among them. It’s pretty disturbing to see the heroines who usually save the day as mindless thralls, especially since one of them is an Alicorn princess.

* The fact that, not only did the elements of Harmony not work on Accord, they worked in his favor and made him spread his mind control even further! He even got the rest of the mane six, Spike and Princess Celestia! If it wasn't for Starlight, he would've succeed in his plan.

* Corrupted Pinkie Pie is basically ComicBook/TheJoker. [[FauxAffablyEvil Funny, but purely psychotic to the core]]...also, her antics result in [[spoiler:the rebirth of Nightmare Moon]], if only for a little while.

** Heck, the entire concept of the Mane 6 suddenly turning evil makes for some great ParanoiaFuel, especially if one of more is your favorite character.

* Adding to the above, corrupted Rarity is essentially a fashion-obsessed ComicBook/DoctorDoom, mask and all!
