History NightmareFuel / FinalFantasyX

* It may be more funny or sad to some, but Rikku's Thunder Plains laughing breakdown and then spider-walk was creepy. It even startles the party.

* [[spoiler:Yunalesca's profoundly creepy OneWingedAngel]].

* [[http://images.wikia.com/finalfantasy/images/d/d3/FFX2-Anima.png Anima]]. Just... every last thing about her. A massive, twisted humanoid giant, chained and hideous. Its appearance is disquieting, but the real nightmare fuel comes when you learn what Anima is: [[spoiler:Seymour's mother, who gave herself as Seymour's aeon because she saw no other way to redeem Seymour in the world's eyes - and later, when Seymour made his FaceHeelTurn, she couldn't stop him from using her as a weapon. Now look at Anima again, and see the pain and helplessness in her face... and then watch her [[https://www.youtube.com/watch?v=LbJJCZQ3hso Overdrive,]] and see her '''anger...''']]

* ''[[DemonicSpiders Freaking]]'' Greater Malboros. Giant desert worms are relatively common. Giant flesh-eating tentacular blobs with dozens of eyes? Not so much, outside Creator/HPLovecraft.
** Malboros are a common enemy across all FF games. The regular Malboros are at least manageable, as they attack normally and only use Bad Breath about 1/3 of the time. The Greater Malboros found in the Omega ruins ''always'' strike first (unless you have someone specifically equipped with a First Strike weapon), and ''always'' open with Bad Breath. And their Bad Breath attack causes many more status ailments (including ones that make you lose control of your character, like Confuse and Berserk). Pretty much the only guaranteed way to survive one is to have at least one character have confuseproof AND berserkproof armor on, or to have a first strike weapon and the flee command.

* The second half of the final dungeon, ''especially'' if you [[NothingIsScarier use No Encounters to prevent random battles from breaking the suspense]]. The sudden blocks that shoot up to bar your path don't help.

* The Farplane. First time through it could seem...only sad. But it's a place where people can see their dead loved ones, or at least their memories of them. It's a [[HarryPotter Mirror of Erised or Resurrection Stone]] type situation. It could be possible that some Spirans have been so broken about losing loved ones that they spend all their time in the Farplane, forgetting their lives for possible mere memories they can't even have a mutual conversation with. The forms of lost loved ones just....stare. It's like looking into the abyss more than seeing a loved one.

* Seymour is a Maester, a powerful Summoner and a calm and collected leader. Then why is the music that plays when the party goes to meet him in Guadosalam, his home, so strangely unsettling? And why is that pendulum so freaky, reminiscent of [[FIlm/ThePitandthePendulum The Pit and the Pendulum]] by Edgar Allen Poe? [[spoiler: It's because he actually was barely hiding the fact that something was a little wrong with him by that point, and indeed, it doesn't take long after that for the truth to be revealed about him. His theme is called "Seymour's Ambition" and later "The Unsent Laugh". Brrrrr.....]]

* Sometimes when Petrified characters get hit, they shatter. They're not dead forever (somehow) so it's [[GameplayandStorySegregation]], but it's still horrifying to see someone burst into a million pieces.

* The Farplane. First time through it could seem...only sad. But it's a place where people can see their dead loved ones, or at least their memories of them. It's a [[HarryPotter Mirror of Erised or Resurrection Stone]] type situation. Could it be possible that some Spirans have been so broken about losing loved ones that they spend all their time in the Farplane, forgetting their lives and anyone alive for possible mere memories they can't even talk to?

*** There's also the small matter of it [[spoiler:vaporising the crusaders and Al Bhed during Operation Mi'henn.]] Which, by the way, [[spoiler:is the same attack it uses to cause the aforementioned NonStandardGameOver]]. One can assume that the party then suffers a similar fate

* Seeing the characters get SwallowedWhole by the Worm type enemies is really disturbing. Seeing them get regurgitated back out is even more disgusting and nightmare fuel inducing.

* While inside the core of Sin just moments from the final battle [[spoiler:in Jecht/Yu Yevon's version of Dream Zanarkand, after sharing some warm words with his son and begging Tidus and his friends to kill him and put an end to Sin, Jecht falls completely under Yu Yevon's control once again. The entire party is freaking out, but it's the fact that [[TheStoic Auron]] shows visible concern and makes a slight gasp of unease at the situation that you know '''Shit Just Got Real!!!''']]

* While inside the core of Sin just moments from the final battle [[spoiler:or at least the first phase, in Jecht/Yu Yevon's version of Dream Zanarkand, after sharing some warm words with his son and begging Tidus and his friends to kill him and put an end to Sin, Jecht falls completely under Yu Yevon's control once again. The entire party is freaking out, but it's the fact that [[TheStoic Auron]] shows visible concern and makes a slight gasp of unease at the situation that you know '''Shit Just Got Real!!!''']]

** [[spoiler:Then, breaking the deathly silence that has fallen over the party, [[JumpScare up pops a humongous mutilated hand covered in flames]], as Jecht pulls himself up and reveals his gigantic final aeon form, complete with pulling out a sword from his abdomen as blood sprays and he groans in pain.]]]]

* Yu Yevon. [[spoiler:He created Sin as sort of an 'object lesson'; it was never meant to be permanent. He also created Dream Zanarkand. Unfortunately, he did both at once and it wiped his mind clean, overwriting it with his instructions for Sin. He can't stop. Ever. He's been rendered braindead to the extent that he's essentially a machine following a program. He died at some point. ''He never noticed.'']]

** The knowledge that [[spoiler: one of your guardians has to die]] is withheld until you get to Zanarkand, unless you are a Maester or another prominent Yevonite.
* The Dark Aeons, corrupt versions of Yuna's regular Aeons. Specifically:

* [[http://images.wikia.com/finalfantasy/images/d/d3/FFX2-Anima.png Anima]]. Just...every last thing about her. A massive, twisted humanoid giant, chained and hideous. Its appearance is disquieting, but the real nightmare fuel comes when you learn what Anima is: [[spoiler:Seymour's mother, who gave herself as Seymour's Aeon because she saw no other way to redeem Seymour in the world's eyes - and later, when Seymour made his FaceHeelTurn, she couldn't stop him from using her as a weapon. Now look at Anima again, and see the pain and helplessness in her face...and then watch her [[http://www.youtube.com/watch?v=LbJJCZQ3hso Overdrive,]] and see her '''anger...''']]

* Speaking of Anima: Baaj Temple, the abandoned, ruined temple you can find her at, and also at which Tidus ends up at after being removed from Zanarkand early on in the game. [[NothingIsScarier Creepy music and absolutely no one present]] save for the resident Fayth ([[spoiler:the aforementioned mother of Seymour]]) as well as Geosgaeno, who terrorizes Tidus at the beginning of the game and nearly succeeds in swallowing him.

* Once you finally get inside Sin, there's a cutscene where the characters marvel at how surprisingly beautiful it looks in there...then suddenly it turns dark, an EvilLaugh is heard and you see a brief-but-horrible extreme close-up of [[spoiler:Seymour]], complete with GiantEyeOfDoom.

* The fact that the Fayth of Bahamut is just a kid. [[spoiler:Remember that the Fayths are actual people who sacrificed themselves to become weapons.]]

* Talk to Maechen at Mount Gagazet after getting the airship. If you take the time to listen to his exposition and put things together, you realize that [[spoiler:Yu Yevon basically rules the entire world with the power of fear and death...and he's been doing this for a ''thousand years'', with no one able to stop him completely until Yuna's party comes along.]]

-->'''Auron''': ''[[spoiler: Summoners challenge the bringer of death, Sin, and die doing so. Guardians give their lives to protect their summoner. The Fayth are the souls of the dead. Even the maesters of Yevon are unsent. Spira is full of death. Only Sin is reborn, and then only to bring more death. It is [[ViciousCycle a cycle of death, spiraling endlessly]]]].''

* While inside the core of Sin just moments from the final battle [[spoiler: Or at least the first phase, In Jecht/Yu-Yevon's version of Dream Zanarkand, after sharing some warm words with his son and begging Tidus and his friends to kill him and put an end to Sin, Jecht falls completely under Yu-Yevon's control once again.

* The Chocobo Eater. The idea that there is something out there that eats chocobos is terrifying, and just before the fight, it picks one up.

* [[VideoGame/FinalFantasyX2 Final Fantasy X-2's]] BonusDungeon has Elder Drakes which can wipe you out without breaking a sweat unless you've been LevelGrinding like mad. Normally, this wouldn't be a problem, as there's always the Flee command... except, it doesn't work on fiends you can see before you fight them. You have to time your run perfectly to avoid them, and they keep jumping out at you - and the ''noises'' they make as they pounce... *shudder*

* While inside the core of Sin just moments from the final battle [[spoiler: Or at least the first phase, In Jecth's/Yu-Yevon's version of Dream Zanarkand, after sharing some warm words with his son and begging Tidus and his friends to kill him and put an end to Sin, Jecht falls completely under Yu-Yevon's control once again. The entire party is freaking out, but it's the fact that [[TheStoic Auron]] shows visible concern and makes a slight gasp of unease at the situation that you know '''Shit Just Got Real!!!''']]
** [[spoiler: Then breaking the deathly silence that has fallen over the party [[JumpScare Up pops a humongous mutilated hand covered in flames]], as Jecth Pulls himself up and reveals his gigantic Final Aeon Form, complete with pulling out a sword from his abdomen as blood sprays and he groans in pain]]

* The fact that the Fayth of Behemoth is just a kid. [[spoiler:Remember that the Fayths are actual people who sacrificed themselves to become weapons.]]

-->'''Auron''': ''[[spoiler: Summoners challenge the bringer of death, Sin, and die doing so. Guardians give their lives to protect their summoner. The Fayth are the souls of the dead. Even the maesters of Yevon are unsent. Spira is full of death. Only Sin is reborn, and then only to bring more death. It is a cycle of death, spiraling endlessly]].''

* Listen carefully to the [[http://www.youtube.com/watch?v=TWVST7P37IM Hymn of the Fayth]] in each shrine. Near the end of the game, it becomes clear that the singer is the Fayth itself. Now listen to the version that plays in [[http://www.youtube.com/watch?v=fgnrXKSOd-Y Yunalesca's chamber]]. It's not only being sung by a full chorus, but they're ''off-key''. [[spoiler:It's all the guardians who sacrificed themselves to create the Final Aeons. And they're in ''despair''.]]
** Anima sounds like the singer is just ''barely'' holding back tears

** Dark Yojimbo. You're just exploring the Cave of the Stolen Fayth, when suddenly it starts CHASING YOU.
