Nightmare Fuel / Final Fantasy V
You said that being a tree equals being Laughably Evil. Say it again now.

It has been said that most of the fun in Final Fantasy V comes from the way it doesn't take itself too seriously. This doesn't mean the cheery tone can be taken for granted.

After Final Fantasy IV's utter horrors and after its After Years, this is the next step into the darkest depths of the pants-shittingly scary Final Fantasy series.

The fact it's a short walk compared to the rest of the series barely reflects the game's nature as a Breather Episode for the series — just as the sequel will quickly tell you.

  • Castle Exdeath, the Disc-One Final Dungeon, starts off as a fairly standard-looking castle. But when the illusions are dispelled on the second visit, it becomes a horrifying Womb Level. 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 darkens the tone of the game whenever he's around, despite having a second-in-command who is a walking, talking Funny Moment. 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 Eldritch Abomination 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 Fight Woosh 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 And I Must Scream! 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?
  • In the Great Sea Trench, there are four types of enemies you can fight. All four are called "Unknown". Here's how they look. What are these?!?! Undead, mutated corpses whose main attacks are to vomit on you, and kill you instantly! Their existence combined with the hazardous floor of that dungeon and the annoying boss compound to make the area terrifying. These monsters wouldn't be out of place in a Splatterhouse game, yet here they are in a fantasy RPG like FFV.
  • 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.
  • Omega and Shinryu, both of which are implied to be the strongest beings in the franchise.
  • Before beating the game, the door to the Bonus Dungeon in the GBA version isn't locked. Instead, opening the door will result in an unnerving noise, the screen going dark, and a dialogue box saying only "It is pitch black inside. You cannot enter." And then there is the dungeon itself. Remember feeling nervous when trying to sneak past Omega? Here, have an entire floor full of them!
  • There is a family of undead enemies that take the form of a floating head with the face ripped off and floating in front of the skull and an elongated tongue feeding from the skull's mouth through the mouth of the face in front (and little stringy bits connecting it to the rest of the flesh on the skull).
  • If you've never played the 2D versions of Final Fantasy IV or Final Fantasy III, you might get an Uncanny Valley 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.)
