History NightmareFuel / KingdomHeartsII

** Before that, at the beginning of the game, Roxas constantly being gaslighted by the people in the data Twilight Town. It’s especially jarring how cold, distant and inhuman they act compared to the real people in Twilight Town. The data town has a fake, empty feeling to it, especially on the final day, where the data people are ghosts who Roxas can no longer interact with and the entire town is just...[[NothingIsScarier empty]]. Doesn’t help that DiZ is toying with Roxas, not caring that he’s essentially exploiting a toddler in a teenager’s body for scientific purposes, considering Roxas is 1 year old by the time of Kingdom Hearts II.

* Losing to a Gambler or Luxord results in Sora being turned into a card or dice. [[AndIMustScream Just the look of his face when transformed]] is horrifying.
* [[VideoGame/KingdomHeartsBirthBySleep Terra's Lingering Will]] in ''VideoGame/KingdomHeartsII [[NoExportForYou Final Mix]]'' would be scary enough without any dialogue due to being a nigh-unstoppable force of destruction in battle, but he becomes far more unsettling because, presumably due to being a living armor, [[TheUnintelligible the guy's voice]] sounds like a distorted, metallic echo. (Though the real reason is far more mundane, as seen in ''VideoGame/KingdomHeartsIII'' where it had proper spoken dialogue: Terra, and any incarnations of him, hadn't yet been given a voice actor.)

* Not the creepiest thing in the game per say, but near the end of your first visit to the Land of Dragons the player is treated to a seen of some of Shen's remaining soldiers turning into heartless likely due to fatigue and despair. It's a pretty morbid reminder that Emblem Heartless were once actual people.

* It was easy to get MoodWhiplash when entering [[TheVeryDefinitelyFinalDungeon "The World That Never Was"]] at the end of the game. It gives off this bizarre feeling of family-friendly existentialism, with creepy background music and floors with names like "The Altar of Naught", "The Hall of Empty Melodies", and especially "Proof of Existence" -- the Nobodies aren't supposed to exist, and they believe their death means absolute CessationOfExistence, so that graveyard-like room is the only proof they ever existed.

** And near the end of the arc, when Sark is grown to a giant, he grabs Tron and tries to crush him. Just looking at Tron's face as he screams in pain over being crushed is enough for one's spine to freeze. Anyone who saw ''Film/TronLegacy'' or played ''VideoGame/KingdomHearts3DDreamDropDistance'' would really find this to be [[TooSoon just too upsetting]].
