* While Garon's [[MemeticMutation groans of increasing discomfort]] are basically just that, mild discomfort, on the ''Birthright'' route, on ''Conquest'' they descend straight into this, with Garon convulsing in pain as if having a heart attack or seizure, with a very UncannyValley expression on his face as he screams.

* While Garon is a source of enough NightmareFuel in the game, the manga takes it UpToEleven. His face is perpetually morphed into a creepy snarl and his eyes are almost always slit, giving him a demonic appearance. And mind that he's like this for all the manga. Hell, the one time his face is normal is when he mistook Leo for his mother.

* Always in the manga, Leo starts to smell ''rotting meat'' at Castle Krakenburg, which gets gradually stronger the closer he gets to the throne room. Reason for that is because Garon has been personally handling executions. You know what's worse? Leo pick up that smell...''outside'' the castle.

--> '''Corrin''': Everyone should just die.

* [[MyBelovedSmother Camilla's]] {{Yandere}} tendencies can easily veer into this territory. In both ''Birthright'' and ''Revelation'', she wants to be the one to [[IfICantHaveYou kill Corrin]] so she can have them back and [[CradlingYourKill hold their corpse]] afterwards, while one of her Private Quarters lines in ''Revelation'' and ''Conquest'' has her immediately offering to kill anyone Corrin wants if it would make them happy. Then there's her threatening to cut off Selena's legs if she tries to leave her and saying she has ''several'' ways of torturing Laslow if he turns against her.

* More mundane than some other examples, but ''VideoGame/FireEmblemFates'' is the first in the series to change the battle theme if one of your characters is likely to die in the ensuing fight, and [[https://m.youtube.com/watch?v=IMLO51LRewo this theme]] consists of PsychoStrings. Luckily, this happens only if you're playing Classic Mode or on your last unit in Casual Mode.

** Leo and Elise's reactions in ''Conquest'' and ''Birthright'' respectively ''really'' don't help: from their perspective, it would be very like [[AdultFear watching their parent having a stroke]].

** In addition to this, the first several episodes of the DLC show that the children's parents are all dead, and some of them even [[HarmfulToMinors died right in front of them]]! The very start of the first episode shows Female Kana holding the Yato in a fog-covered forest, lost and wandering around, having been traumatized by the Male Avatar's death. Like in ''Awakening'', the very idea of these children losing their parents and living during an apocalypse [[AdultFear is pretty unnerving]].

** And that brief image you get isn't anywhere near as bad as actually seeing him face-to-face. Slime Garon is '''huge''', much bigger than you'd expect from that crystal ball vision. And the first thing he does is try to murder his entire family [[HeKnowsTooMuch for seeing him in his true form.]] Not to mention [[https://www.youtube.com/watch?v=fr_eYcnSHX8 the boss theme]] that plays for him on ''Conquest'', which really sums up the feeling of "'''WHAT THE HELL IS THAT THING?!'''"

** Its truly horrifying nature is perfectly demonstrated with Takumi in ''Conquest''. He first becomes 'infected' by accidentally falling into the gap between the dimension and landing in Valla, which is under Anankos's rule. The possession first takes his already existing resentment and distrust towards the Avatar and [[MoreThanMindControl slowly twists it into homicidal hatred that begins to consume everything else about him]]. Throughout the route, it becomes worse and worse until Chapter 23, where after the party defeats him for the last time, Anankos ''[[PsychicAssistedSuicide forces him to commit suicide]]'' so he can take over Takumi's body entirely. In the last chapter, Takumi is nothing but a corpse held up only by Anankos's possession, forcing the party to MercyKill him. And the worst thing about this? ''[[AndIMustScream The poor guy is entirely aware of what is happening and is begging for death.]]''

---->'''Takumi''': Betrayal... betrayal... [[IAmTheNoun I AM BETRAYAL!!!]] ''[Nightmare Face]'' [[note]]If you take a good look when the screen zooms at his eye, you can see what can only be described as pure terror reflected in it. [[AndIMustScream Yes, he knows exactly what is happening and has no way of stopping it.]][[/note]]

** Related to the above, [[CameBackWrong Scarlet, who has a more subtle, but still very disturbing, portrait.]] And as this boss is nothing more than an EliteMook in terms of her map role, [[JumpScare you'll probably end up running into her portrait while casually scrolling through the enemies, not expecting it.]] And if you're feeling particularly cruel, you can still marry her on this route, recruit Kana, and force her to fight her zombified mother, knowing the ''only'' way to save her is to MercyKill her...

* Even when he's not possessing some poor soul, [[DraconicAbomination Anankos]] can be pretty terrifying. He's a dragon with enough power to practically be considered a ''god'' and, like all of the dragons that have lived too long in this series, has gone completely insane. He's masterminded the whole conflict between both Hoshido and Nohr, and creates entire armies of familiars and puppets, sometimes from the corpses of other people ''which still retain their memories'', to do his bidding. His real voice ranges from a very deep booming baritone to demonic growling as he rambles on about how he was left forgotten and betrayed by humanity. In chapter 27 of ''Revelation'', the first form he takes is a ''giant head'' of a stone statue of himself that is kept perfectly frozen while it talks, and cracks apart whenever he roars. Then his dragon form is revealed and it's ''freaking massive''. This quote from Chapter 18, when he shows up seemingly out of nowhere and tries to kill you, sums up just how terrifying he can truly be.
-->'''Anankos''': ''I AM THE FORGOTTEN DRAGON, THE BETRAYED KING, THE ENTOMBED GOD. IN THE NAME OF THE KING OF VALLA, I SENTENCE YOU TO DEATH!''

* Marry Peri to either Odin or Laslow. In their married ending, it's heavily implied throughout the game she's been abducting and murdering random civillians, before disposing of their bodies so well they're never even found. Yikes.
