History NightmareFuel / FinalFantasyV

** There's one enemy (and a BonusBoss in a few versions) that will use an attack named Paraclete on any KO'd characters to turn them into a zombie. This attack's animation is like the one for the Raise spell, except the angel reviving the character is zombified in a similar manner.

* Castle Exdeath, the DiscOneFinalDungeon, starts off as a fairly standard-looking castle. But when the illusions are dispelled on the second visit, it becomes a horrifying WombLevel. The thirteen story-tall castle is constructed entirely out of the breathing corpses of Exdeath's victims. The walls visibly pulsate and the background music changes from the heroic "The Dawn Warriors" associated with Galuf to its own sinister tune.

* Castle Exdeath, the DiscOneFinalDungeon, starts off as a fairly standard-looking castle. But when the illusions are dispelled on the second visit, it becomes a horrifying WombLevel. The castle is constructed entirely out of the ''breathing corpses'' of Exdeath's victims. The walls visibly pulsate and the background music changes from the heroic "The Dawn Warriors" associated with Galuf to its own sinister tune. Also, this monstrous construction is thirteen stories tall and one of the biggest structures on the overworld. All made out of fused corpses. This also emphasizes the next point....
* Exdeath himself pretty much [[KnightOfCerebus darkens the tone of the game whenever he's around]], despite having a [[TheDragon second-in-command]] who is a walking, talking SugarWiki/{{Funny Moment|s}}. He's a tree. Seems harmless enough. Except that he's a tree that was used to seal countless monsters and demons. The souls of these demons became ''so smashed together and compact'' that they fused into one blasphemous warlock that was so powerful, the four greatest warriors in the world couldn't even kill him and had to settle for sealing him somewhere else.
* Pictured is Exdeath's form once he gains the power of the Void: An EldritchAbomination of a tree that looks more like brain matter than wood, with an inhuman face on the trunk and his familiar torso armor sticking out of his head, giving the impression that he's taken root. After the Void turns against him, his body implodes and then spills out with a legion of demonic horrors fused together that could either be his original demons or the other horrors sealed in the Void, or both. And it takes up most of the battle screen.
* Mirage Village is a village that is trapped between dimensions. No time passes inside, and the village itself is hidden in a lush forest with no sprite on the overworld that indicates its existence, but when you step on its tile on the overworld, you don't simply enter it -- the game's FightWoosh plays beforehand. But, if you go to the place through the Rift, you will see ''every single'' being that lives inside are frozen; not by ice but by time. And from some NPC, it can be indicated that their frozen selves are their original form and they are aware of the phenomena. The village is one big habitat of the AndIMustScream! And the creepy "Book of Sealings" music that plays in the background of what otherwise looked like a perfectly normal town....
* Moogle Eaters. Does somebody have to explain why they might have that name?

* The Interdimensional Rift can get incredibly creepy at times, especially thanks to the music. Though it's not as mindbending or disgusting as some of the things detailed above, the Castle area should be mentioned--most players will have the Thief's Find Passages as a passive ability by this point, showing all the paths around the floating platforms in the sky. But it's a little unsettling not to have it and imagine how it must be for the characters, walking around on invisible paths over a bottomless sky.
* [[WeaponOfMassDestruction Omega]] and [[CrystalDragonJesus Shinryu]], both of which are implied to be the ''strongest beings in the franchise''.
** Shinryu is an immensely powerful dragon that traverses the various worlds, either searching for Omega or [[FateWorseThanDeath pulling a]] [[VideoGame/DissidiaFinalFantasy Dissidia]] on whatever place he ends up in.
** Omega was created by a civilization from another world specifically to destroy Shinryu. Only problem; it was so powerful and dangerous that [[SealedBadassInACan it was banished to the Rift]] [[KillThemAll after causing mass destruction on the world it originated in]].
** [[FromBadToWorse For added nightmares]], [[OhCrap these things travel the entire Final Fantasy multiverse in search of each other.]] [[FridgeHorror Should they ever]] [[ApocalypseHow come in contact...]]

* If you've never played the 2D versions of ''VideoGame/FinalFantasyIV'' or ''VideoGame/FinalFantasyIII'', you might get an UncannyValley feeling off of Krile's 3/4 view battle sprite. (But if you have... well, you still might, but you'll also know it's their standard child sprite.)
* The mobile versions renders the monsters in high-quality sprites that fully match their original concept artwork. This allows players to see a number of ''really horrifying'' details that had previously been obscured by pixellation.

* The method to finding hidden character Gogo. You '''literally''' have to allow this worm to swallow your entire team up and then venture through [[WombLevel its stomach until you find the aforementioned character, who apparently has been living here for quite some time]].
