History NightmareFuel / PokemonXenoverse

* The player's introduction to the first X Pokémon, [[PlayingWithFire Elekid X]], is to witness a wildfire ''in the middle of a city'' caused by it. While Aster is able to extinguish the fire before it causes any real damage, it's a stark warning that even the [[WarmUpBoss easiest X Pokemon to deal with]] can still be a major threat if left unchecked.

** Finally, after a BaitAndSwitchBoss fight against Team Dimension's Colonel Dahlia, Victor reveals that by unleashing your Alter, [[NiceJobBreakingItHero you've given him exactly what he needed]], and proceeds to transform his [[InfinityMinusOneSword Tyranitar]] into an X Pokemon... which then ''demolishes the Quasar express with a single attack''. While the main characters survive the derailing, the Quasar Express- which was explicitly referred to as a regional treasure- is demolished, marking Team Dimension's first real, unambiguous victory. '''Damn.'''

* While storming Team Dimension's spacecraft HQ, the protagonist has to fight A and B (who have [[FusionDance fused into a single robotic entity named S]]) and Dahlia again, and just like Victor, each of their their [[SignatureMon signature Pokémon]] has been transformed into an X Pokemon. While S's Bisharp X isn't too bad (it's a bulkier fusion of A and B's Bisharp), Dahlia's Scovile X is noticeably more unnerving- it's regressed from bipedal to quadrupedal, and its tail has become a roughly tail-shaped burst of electricity. Victor's Tyranitar X also deserves mention, as its hands have morphed into ''[[BodyHorror pincers]].''

* Over the course of pass 2, you have to face multiple Pokemon that have [[SuperMode Mega Evolved]] on their own, something that should normally be impossible. Special note goes to the 2 Mega Charizard you have to face in a burning-down Sunshine Circus. Oh, and to make matters worse, you have to fight new Mega forms of [[OlympusMons Raikou, Entei, and Suicune]].

* Pass 3 is where things really start kicking into high gear, where you must explore an AbandonedLaboratory with GEIST, Caspar, and Versil. The entire area has an ominous, tense atmosphere, and is infested with Ditto X, which are stated to be far more hostile than regular Ditto. And it shows, as you fight [[BossRush multiple Ditto X transformed into previous X Pokemon you fought as bosses]], up to and including [[OlympusMons Mewtwo X]].

** After finally reaching Versil and Dragalisk, the protagonist engages Dragalisk in battle... and it NoSells everything thrown at it. It's a good thing that [[GodOfGood Luxflon]] was able to intervene in time, or Dragalisk would have almost certainly killed everyone!

* After obtaining [[DropTheHammer Aegislash X]], you go back and enter [[EldritchLocation Altered Mt. Zodiac]], which has become a mess of weird environments and surreal imagery as a result of the [[OlympusMons X Tapus]] going berserk.

* [[spoiler: Dahlia ends up getting [[DemonicPossession possessed]] by [[HatePlague Fury Energy]], serving as Pass 3's last boss. It's a [[ThatOneBoss brutally hard fight]], and when you try to use the Fury Seal on her, [[OhCrap it breaks]], and she ends up in a coma.]]
* There's a side path in the bunker with a unique background music, consisting only of creepy noises and the giggling of a little girl. Not helping is the "RUN!" message written in [[CouldntFindAPen blood on the wall]]. You never find out the purpose of this place [[spoiler: until Pass 5, where it turns out to be where you can find and catch [[OlympusMons Mewtwo]].]]

* As you confront the Tapus, the Cardinals all speak ominously about some alien presence at the top, addind a sense of dread to the already chaotic situation.
* Upon reaching the peak, [[spoiler: you step through a portal to a place called the Event Horizon, where you meet the presence and discover that it is Vakuum, the entity fought at the end of the Team Dimension arc. This time however, it has taken on a [[BishonenLine human form]], and tells you its plan: it wants to pull a GrandTheftMe on you. This leads to you battling it, this time as a trainer, where it uses the game's resident InfinityMinusOneSword, Egorgeon, and then [[OlympusMons Tornadus, Thundurus, Landorus, and Enamorus]], all of them having [[TheComputerIsACheatingBastard illegal moves and abilities]].]]
* [[spoiler: After this, Vakuum uses the [[HatePlague Fury Energy]] to resurrect Dragalisk, resulting in a final battle against its new form, [[BishonenLine Dragalisk X]].]]

* The pass starts off rather innocuously, with you going to take part in a new tourney at the Apollo Tournament. [[spoiler: You face Looker, then Versil, who spends a suspicious amount of time talking about how he has repented for his actions. But the kicker is the last opponent, Trey. [[SpottingTheThread You know, the Trey who's supposed to be dead?]] After you beat him, he flat out points out to you that he shouldn't exist, revealing that you're in a LotusEaterMachine created by Vakuum as a last ditch effort to stop you from interfering with his plans!]]

* You then spend most of the pass playing as your [[EvilCounterpart Alter]], [[AnotherSideAnotherStory seeing the story from their perspective.]] The [[DarkWorld Xenoverse]] areas you traverse through are all thoroughly unpleasant and eerie. Small wonder your Alter was [[GreenEyedMonster jealous of you]].

* [[spoiler: Dahlia ends up getting [[DemonicPossession possessed]] by [[HatePlague Fury Energy]], serving as Pass 3's last boss. It's a [[ThatOneBoss brutally hard fight]], and when you try to use the Fury Seal on her, [[OhCrap it breaks]], and she ends up in a coma.

* After obtaining [[DropTheHammer Aegislash X]], you go back and enter [[EldritchLocation Altered Mt. Zodiac]], which has become a mess of Bizaarchitecture and surreal imagery as a result of the [[OlympusMons X Tapus]] going berserk.

** Even after Vakuum is unfused, Dragalisk still attempts one last push into Earth through the portal left behind by Luxflon, forcing Trey to preform a HeroicSacrifice by detonating a bomb implanted in his cyborg body as a failsafe. While just the idea that a person was rigged to explode as a last-ditch effort to stop an enemy is scary, it hits harder from Versil's perspective- [[AdultFear he's essentially watching his adoptive son die to fix a problem he recklessly caused]].

* The first encounter with Team Dimension at Newtron Campus is mostly silly thanks to the antics of the [[RidiculouslyHumanRobots Ridiculously Human]] MechaMooks, and even the higher-ups, the robotic twins A and B, seem more interested in giving the player their autographs than fighting them at first. Then you actually get into a battle with them... and it's a ''HopelessBossFight''. Oh, and not the [[LordBritishPostulate "winnable if you're sufficiently prepared and try hard enough"]] kind of fight- [[ControllableHelplessness the game is hard-coded so that they knock out your Pokémon in one hit, while your Pokémon are hard-coded to do absolutely no damage to them in return.]] It's only due to the [[PlotDevice Earth Plate]] they were trying to steal giving your starter a new form and a HeroicSecondWind that they are prevented from having their Pawniard straight-up ''execute'' you. It's a nasty wake-up call that [[BewareTheSillyOnes for all their silliness, Team Dimension is a credible threat]].

* During the events at the Shyleon Temple, Victor uses a Roserade X to brainwash the local guardians into giving him and Trey access to the temple's Xeno Gate so that Trey can harness Blue Energy. It's unnerving at first, but not too scary... until you catch the Roserade X and learn that it was controlling the locals not through PsychicPowers, but by using high-pitched sound frequencies to directly screw with their bodies and minds, with the PokéDex and Chuta confirming that the process is potentially ''fatal''. It's a good thing the protagonist and Ruta arrived when they did, or else Victor's ploy could have straight-up killed Chuta!
** Some additional FridgeHorror: Gengar X has showcased similar mass mind control abilities, and was being transferred by Team Dimension on the Quasar Express en route to the Shyleon Temple. It's likely that Gengar X was originally going to be used by Team Dimension to brainwash Chuta and his guards, but Team Dimension had to pivot to using Roserade X after the protagonist's actions on the Quasar Express led to Gengar X being freed. In other words: ''[[NiceJobBreakingItHero the protagonist is indirectly responsible for endangering Chuta and his guards]]''.

* After you defeat your [[EvilKnockoff Alter]] and gain the Xenoversal Core and Ring during the protagonist's visit to Starburst Mountain, you are instructed to give the Xenoversal Ring to power up your starter further. It works... but the Xenoverse's influence causes your starter to ''[[WithGreatPowerComesGreatInsanity go ballistic]]'', [[FightingYourFriend resulting in a boss fight against it]]. This hits harder when you realize the protagonist has lived with their chosen starter for years; to them, the experience would be like watching your pet get rabies and having to put it down. Fortunately, you're able to safely get it to regain control of itself after the battle, and it's able to utilize its Xenoversal Evolution without incident for the rest of the game.

* The encounter with [[BigCreepyCrawlies Galvan]][[AnIcePerson tula X]] in String Forest. When you first enter, it has already heavily affected the environment by its mere presence, with a permanent hailstorm covering the forest and several item chests being frozen over. Still, it's nothing too scary at first... until you get to a clearing at the end of the forest, where it has ''caught several humans in its freezing web'', one of who comes to and can only muster the strength to utter a simple "get out". Unfortunately, it's too late- the camera reveals that the Galvantula X and its Joltik X children have the player surrounded, complete with ScareChord. The even the splash screen for the battle (the current page image) is terrifying, with the Galvantula X and Joltik X [[TheDarknessGazesBack staring out from the gloom]].

* After you defeat your [[EvilKnockoff Alter]] and gain the Xenoversal Core and Ring during the protagonist's visit to Starburst Mountain, you are instructed to give the Xenoversal Ring to power up your starter further. It works... but the Xenoverse's influence causes your starter to ''[[WithGreatPowerComesGreatInsanity go ballistic]]'', [[FightingYourFriend resulting in a boss fight against it]].
