We all know ''Franchise/{{Pokemon}}'', don't we?

You know Pikachu and all his adorable friends, battling each other in a [[CrapsaccharineWorld Crapsaccharine]] DeathWorld with soul-stealing monsters, horrifying ghosts, and terrorists worshiping [[ApocalypseHow apocalyptic monsters]], and [=NPCs=] that will stop at nothing to hunt you down and fight, where even the music itself is enough to give you nightmares... [[SchmuckBait On second thought, maybe not]].

The following works have their own page:

[[folder:Other Horrors]]
Anything else that doesn't fit in other categories.

* Attempting to capture Kyogre in ''Pokémon Sapphire'' is surprisingly scary enough, but the analogous bonus stage in the ''Ruby''/''Sapphire'' pinball game is much worse. The stage is nearly as dark as the ocean floor would be in real life, and the player initially only sees Kyogre's eyes, leading to the feeling of being menaced by an invisible predator. The minimalist eerie music aggravates the uneasiness.
* The [[RedEyesTakeWarning look in Entei's eyes]] when he puts a spell on Ash's mom in ''Spell Of The Unown''.
-->'''Entei''': [[PunctuatedForEmphasis You... are... MAMA!]]
* The eighth movie gives us a scene in which [[ItMakesSenseInContext the Tree of Beginning's]] antibodies consume both members of Team Rocket. Jessie's slowly pulled into an antibody's maw, screaming like mad and begging James to help her.
* ''VideoGame/PokemonSnap'':
** You can take a photo of anything in-game, including jewels: when their photos are developed, you get SpookyPhotographs as a reward. Also, [[http://www.youtube.com/watch?v=sGUEgFSm7Gk&feature=related Charmander]] can get pretty screwed up.
** The HeartbeatSoundtrack when you encounter Mew; it gets faster the closer you get to breaking it out of its bubble.
* In the Gen II games, the aptly-named [[ExactlyWhatItSaysOnTheTin Dark Cave]] can be accessed before getting Flash. It wouldn't be wise to do so, because it's easy to get stuck without knowing the way out. As a workaround, Generation 3 has a cave like this as well, where players actually can see, but only a small circle around them.
* The character "Imakuni?" (question mark included) in the Pokémon Trading Card Game for [=GameBoy=] is a pretty unnerving character who has scared quite a few kids, mostly because of his theme song, coupled with the lack of context: he's actually a cameo of a Japanese singer, his realistic-looking card not meshing well with the [=GameBoy=] style and he is labeled as "Strange Lifeform Imakuni?" which indicates he is a some kind of space alien. He's even ''worse'' in the sequel, where there's two of them. One has a red outfit and his portraits look like he's screaming.
* The church in Hearthome City [[NothingIsScarier lacks any BGM]], and is the only place in the city labeled as "Foreign Building". The people inside it and their NavelGazing come off as really creepy.
* [[http://www.youtube.com/watch?v=Fu0l2JOq_1Y Giratina's grand entrance in Platinum]], pictured above. It becomes even more nightmarish when Giratina turns its wings into giant claws and does a honest-to-goodness JumpScare at the screen. Even worse? ''[[Anime/PokemonGenerations It's been]] [[https://www.youtube.com/watch?v=UOIPUi5k6MA officially animated]]''.
* The Nurse Joys in the Pokémon Centers, whose "Hope to see you again soon" message, coupled with [[TraumaInn the reason you're in a Pokémon Center in the first place]], comes off as creepy. Probably, this is why the line has been changed to "come back anytime" in Heart Gold and Soul Silver, but it was changed back to "We hope to see you again" in both sets of Gen V games.
* Pokémon Crystal introduced moving Pokémon sprites. It was a neat idea, but can be creepy in the Silver and Gold remakes. For example, when Noctowl is sent into battle, it turns its head around. But not to look at its trainer...to look at the [[TheFourthWallWillNotProtectYou player]].
* Encountering the Legendary Beasts in Crystal and HGSS can be creepy: walking along in the tall grass, maybe to level grind, maybe to try and catch a few wild Pokémon, who knows, nothing out of the ordinary for a while, and then... another RandomEncounter, but [[http://www.youtube.com/watch?v=y8Pgfp4JYW0 the music]] is different. And then an enormous beast appears instead of a local Pokémon and disappears as quickly as it arrives.
* The [[http://www.youtube.com/watch?v=8SMzP7svTOE "bus driver" ad]] that played in Western countries is downright horrifying. Well, okay, just how malevolent that guy is can be [[{{Narm}} hilarious]], but considering how buses are a regular part of many schoolchildren's lives...
-->''Hey, little buddy. Wanna ride?''
* In the manga, being possessed by the Red or Blue Orbs for too long can turn your body to dust. While this is creepy in itself, here's the catch; in [=HeartGold=] and [=SoulSilver=], they're key items. They're key items in Ruby and Sapphire as well, though the one you get calms the version mascot rather than awakening it.
* In the anime movies, each and every time Mew is involved, something bad happens:
** The first time Mew was seen in the Anime. It was by a scientist who wanted to bring his deceased daughter back, to that end, he was hired by Team Rocket to make a clone of Mew. The clone: Mewtwo, has cloned other pokemon as a result and fought mew to such a standstill that it took a HeroicSacrifice to stop the fighting.
** Then there's the Mirage Mew. Created as part of a plot to create the ultimate army of pokemon in an allegory of hacking. This one pulled a HeroicSacrifice to stop the villain's plot.
** Then finally we have Lucario And The Mystery of Mew. In which the mew featured there was the guardian of an ancient tree (and syncronized with said tree). One filled of antibodies that captured the human charaters. When the mew fixed that little issue It got itself sick in the process whoch got the tree sick and caused worse things to happen. It took a HeroicSacrifice from Lucario to avert the disaster.
** Noticing a pattern? The Mew that were featured were neutral at best. But they were always involved with some disaster that needed a HeroicSacrifice to avert. Mew maybe very well be an extreme UnwittingInstigatorOfDoom, capable of bringing disaster without knowing it. Dooming someone or something to kill itself to stop this disaster. Even when its cameo was that card, it caused trouble because it's what set one man off on a quest to get four unrelated OlympusMons and throw nature out of whack as a result.
* Type effectiveness
** Ever wonder why Fire is super effective on Steel-types? Because metal warms up pretty fast, and sometimes it can even melt. Even assuming it doesn't liquefy though any significant heating seriously weakens most metals.
** Bug type's weaknesses are Flying, Fire and Rock, respectively symbolizing they're being eaten by a bird, burned alive, or being smashed by... well... [[ShapedLikeItself a rock.]]
** Dragon's weakness to Ice makes little sense... until realizing that most dragons are reptiles: cold blooded. You're shutting down its metabolism by freezing it half to death.
** Psychic being strong to Fighting seems like simple "brain vs. brawn". That, or trying to resist telekinesis using sheer brute force at the expense of the body. Or perhaps even more horrifying--Psychic-types tend to be mind-readers and future seers. A Fighting-type likely spends days training and coming up with strategies against their opponents. Pit against a Psychic-type, however, and all of that practice and strategy is immediately turned against it; the Psychic-type [[ParanoiaFuel can see everything the Fighting-type is going to do before it does it]] and can now counteract everything its opponent throws at it.
** Ice types are weak against Fire, Fighting, Rock, and Steel. Fire melts ice, and the later three are about breaking ice, then realized that some Ice Pokémon, are made of ice, hence you are destroying their bodies, which are easy to break.
* Trying to print something from ''Gold/Silver/Crystal'' with no GameBoy Printer attached results in an error screen and start playing a strange, haunting and slightly depressing little melody.
* [[VideoGame/PokemonGoldAndSilver HeartGold and SoulSilver]]. Arceus event. [[ArtShift Real-life images in a sprite-based game.]] Cue the MindScrew.
* Some of the Pokémon card images from the early sets were rather disturbing. Particularly [[http://bulbapedia.bulbagarden.net/wiki/Gastly_(Base_Set_50) Gastly]] from the Base Set.
** There was always something unnerving about the [[http://bulbapedia.bulbagarden.net/wiki/File:PorygonBaseSet39.jpg Porygon]] and [[http://bulbapedia.bulbagarden.net/wiki/File:ClefairyDollBaseSet70.jpg Clefairy Doll]] cards as well. Also, there's [[http://bulbapedia.bulbagarden.net/wiki/File:BS73ImposterProfessorOak.jpg Impostor Professor Oak]] and [[http://bulbapedia.bulbagarden.net/wiki/File:Imposteroaksrevenge2.jpg his revenge]] from one of the later sets.
** [[http://24.media.tumblr.com/83d6e109559defa58bc702c90970e81a/tumblr_mp83vtUc6e1rzb9yvo1_400.jpg Dark Omastar]] will eat your face.
** Some of the sketchier art, such as the Diglett in the Rocket set.
* ''[[Anime/PokemonZoroarkMasterOfIllusions Zoroark: Master of Illusions]]'', when Kodai edits the movie clips out (where Suicune's surf may have killed sleeping Pokémon, and Entei's paws burning everything below it). What might have happened is [[NothingIsScarier even worse when left to the imagination.]]
* In Black & White, there is a post-game town known as "Lacunosa Town". The people there say that thousands of years ago, a meteorite crashed in the Giant Chasm. In it, it contained a monster (Kyurem). The monster (Kyurem) was said to have eaten both Pokémon and people.
* The Thundarus/Tornadus event in Pokémon Black & White, where a route attendant says that there's a huge storm going on at Route 7. For those unsettled by storms in the first place, just how huge they are is unpleasant. Then, players have to actually chase the storms, and when the legendary Pokémon is met, they're rewarded with [[https://www.youtube.com/watch?v=QCkmgssjhvo this battle music.]]
* In the anime, the character J is a bounty hunter who turns Pokémon into stone to sell to her clients for a high price. One of the episodes she appeared in, ''Pokémon Ranger and the Kidnapped Riolu! (Part 2)'' shows that a Riolu she'd [[TakenForGranite captured]] was still able to reveal its location to Ash using their aura connection. This means that [[FridgeHorror when J turns Pokémon into stone,]] [[AndIMustScream they can still think and are fully aware of it.]] One of the targets she petrified wasn't even a Pokémon at all, but Pyramid King Brandon. J also tried to murder Ash. Most villains in the anime would try to push him to the side to continue their plans, but J, on the other hand, tries to kill him. It seems that in every episode she appears in she tries to murder Ash, if he messes in her plans. She's almost like the anime version of [[TheSimpsons Sideshow Bob]].
* Almia Castle in the second Pokémon Ranger game. An abandoned castle up north that's literally frozen. And it's kinda easy to get lost. Additionally, its kitchen is messy.
** The Chroma Ruins, which are filled with ghost type Pokémon. The fields around it are constantly covered in dark mist, which is made by a Murkrow that's been hypnotized and forced into it.
* At one point in ''VideoGame/PokemonRanger: Shadows of Almia'', you have to save the Cargo Ship from sinking with you, Barlow, and all the Pokémon on board. If you fail the TimedMission, all you get a single chilling line of text over a black screen. That's right; you can '''die''' in a ''Pokémon'' game.
--> The ship slid beneath the waves...
* Black 2 and White 2 take the ''very'' idea of StockholmSyndrome and abusive Trainers and chillingly twist it just a little bit. In PokéStar Studios, the movie series Timegate Traveler introduces this concept. Particularly with an evil Ledian of the Future, who explains that in this future, Pokémon catch humans (no, this isn't Soviet Russia). They're forced into Human Balls and made to do whatever their Human Trainers tell them. Sound disturbingly similar? Yep, the plot to the game, just twisted into a movie N could probably appreciate. It's made worse by the fact that Ledian is a jerkass, threatening to kill it's Human if it doesn't obey orders, the fact that the Human can STILL TALK AND REASON, but has no choice but to obey, and, if the player character ''loses'' the battle, they're forced to run from Ledian and other Pokémon that may try to capture them, thus living exactly like the Wild Pokémon do, and in constant fear. Another installment features a possible ending where the player character is ''captured'' and, much like a captured Pokémon, becomes perfectly obedient...
* Speaking of Timegate Traveler, how about the bad ending of the first movie? If the Temporal Transport knocks out your Solosis (which will most likely happen if you pick either of the bad dialogue options), the Temporal Transport explodes, leaving your experiment a failure, and then you find out that you've merged with your Solosis, thus marking the end of your research for good. Another bad ending turns out that once the character does manage to get back to his own timeline. He unknowingly takes a stone back with him, which Ledian had already purposely slipped into his pocket. Having already expositioned that the stone was what caused the Pokemon to evolve and overthrow the humans. In other words, Ledian and yourself just created a paradox dooming the future.
* The animated trailer for ''VideoGame/PokemonBlack2AndWhite2'' confirms that the villains aim for the trainers when attacking. Makes the battles against them more serious, sure, but there's one time where it unambiguously happens in-game. When you happen on Ghetsis and Kyurem in the Giant Chasm, you're not challenged to a battle. No. He uses Kyurem to attempt to ''freeze you solid where you stand'', not even allowing you to let any of your own Pokemon out to defend yourself. Yes, Ghetsis ''forces'' Kyurem to [[CruelAndUnusualDeath murder you in]] cold blood [[CruelAndUnusualDeath with Kyurem's deadly signature move "Glaciate"]] while you just stand there, helpless to do anything. [[DarkestHour You're gonna die, and you can't do a thing about it...]] you just stand there, likely crying, [[HeroicBSOD paralyzed with fear,]] awaiting your inevitable death. Oh and that's not all. Ghetsis even states that he will freeze you first, likely to the point of near-death, but not quite since he's a butt, and while you're permanently frozen, you get to watch everyone and everything else freeze as well. He only freezes you first just so you can [[AndIMustScream watch everybody suffer and die while you are frozen forever, unable to scream, unable to cry, and unable to do anything about it.]] Unable to save your friends, family, anybody from Kyurem's icy wrath. Not to mention that you've worked so hard to defeat Ghetsis and he's about to kill you. Not defeat, using a Legendary Pokémon to actually [[KilledOffForReal end your life.]] That is the most sick, twisted, evil, demented, and all-around [[MoralEventHorizon CRUEL AS HELL]] action that any villain in Pokémon has ''ever'' done to somebody. It takes nothing short of a BigDamnHeroes moment from N to thwart the attack. The worst part is that according to N and Hugh, Kyurem sounded sad and was forced to do this ''against its own will''.
* The scene where Reshiram/Zekrom fuse with Kyurem is pretty horrific in itself. Then it becomes a complete '''''monster''''' And you have to fight, not capture because of Ghetsis' cane, ''fight'' Ghetsis' newly-created EldritchAbomination, newly named White Kyurem (If fused with Reshiram,) or Black Kyurem (If fused with Zekrom) once it is fused.
* The concept of reviving Pokemon from fossils. Doesn't help that the characters in Red and Blue don't say clone, but revive or resurrect, implying they're BackFromTheDead.
* And then, there's ''[[http://fc02.deviantart.net/fs71/f/2013/309/2/4/espurr_by_kawiku-d6t66gw.png Espurr]]''. With its ''[[ThousandYardStare eyes]]''. And the implication of being a psychic bomb ready to explode, ''at any time''....
* Accidental Nightmare Fuel: [[https://www.youtube.com/watch?v=gyrkENqw7Eg the Slowpoke Song]]. There is something [[UncannyValley unnatural]] about it.
* Takeshi Shudo's [[LightNovel/PocketMonstersTheAnimation novelizations]] depict the world of the anime as a CrapsackWorld, with Gym Leaders being fired if they lose three matches, 10-year-olds being legal adults and having to pay taxes, go to jail, or marry, and many, many fathers and grandfathers leaving their families only to get nowhere on their Pokémon journey. Shudo apparently wanted Pokémon to end with a revolt or rebellion of the Pokémon, who made Pikachu their leader and Meowth some ambassador or translator, and Ash would realize his dream of becoming a Pokemon Master was a childish dream that he needed to wake up from.
* The Drought effect in ''Omega Ruby'' is even more sinister when you think about it. During a Pokemon battle, instead of just shining the strong sun weather effect, the sky is a ''fiery orange'', accompanied by random sparks of embers. It's as if the sky is actually burning and the world will burst into flames at any moment. Have fun trying to unthink that while listening to the ominous Drought tune. Also, playing at nighttime will not save you, [[GameplayAndStoryIntegration the sky is still burning and it's still daytime.]]
* Zinnia from ORAS. Her childlike speech patterns and behavior as well as the strange and animalistic movements she makes at the start of her battles unnerved many. Never mind the fact that she's the one of the last survivors of an ancient tribe of Dragon-type masters and commands an entire team of them. And can use Mega Evolution.
* Also from the Delta Episode is Deoxys's entrance. Basically, Mega Rayquaza destroys the meteor... but in the debris, we see a floating triangle, which begins moving in the very same way the one on Birth Island did as it turns red... and then four black tentacles come out as Deoxys's battle music starts up, (Which has a rather unnerving beginning.) then it bursts open and Deoxys comes flying straight at us, leading into a battle against a ''Lv. 80'' Deoxys. [[labelnote: note]]This is the same level as Arceus in D/P/Pt and ''ten'' levels higher than the Rayquaza you just caught.[[/labelnote]] Anyone who did the original event will probably be shocked as the triangle begins moving and the music starts- Anyone ''without'' knowledge of it will probably be freaked out at the creepy tentacles and then be shocked as Deoxys appears.
* In ORAS, soaring on one of the Eon duo is relaxing... unless you have either a Castform or both Thundurus and Tornadus in your party, in which case, you get to see a giant, eerie thunder cloud which makes loud noises to boot, containing either Thundurus or Tornadus if you have Castform, or Landorus if you have the other two. It's reminiscent of running into a Bigocto in ''The Wind Waker''.
** Additionally, Dialga, Palkia, and Giratina appear in a ''massive'' rift in the sky, although whether or not that's creepier than the above is a matter of opinion.
* In Omega Ruby, right before you fight Tabitha at Mount Chimney, he opens his eyes for the first time. They are bright red, while at the same time he gives a slasher smile.
* Also in Omega Ruby: Courtney is freaking ''weird''. In the original Ruby, she was simply a GigglingVillain and laughed at virtually every time she spoke. Now, she's like an unholy mesh between a robot and some disturbed child, most of the time showing no emotion except for occasional outbursts of anger. Even her cute design doesn't take away from this. (It might even make it ''worse''.)

"Deleting..."\\
'''"[[PunctuatedForEmphasis Don't. Get. In. My. Way.]]"'''
* Pikachu's voice in Pokemon Yellow. Ikue Ōtani's Pikachu voice is normally cute as heck, but the Game Boy's extremely strict hardware limitations distorted it into a [[HellIsThatNoise horrific, staticy mess]] that WILL make you scramble to turn the volume all the way down.
* The animation for Snorlax's Pulverizing Pancake, especially the beginning, where it's just lying there...then suddenly lifts its head up and looks straight at the camera, [[GlowingEyesOfDoom eyes glowing]] and [[RedEyesTakeWarning briefly flashing red]] with a quick but echoing roar. Then, in an instant, it gets up and lunges at you. [[https://www.youtube.com/watch?v=CsTuHGpLJfM See it here.]] Better think twice before taking out that Poké Flute.
* For the 20th anniversary, someone made a series of videos focusing on different Pokemon types.
** [[https://www.youtube.com/watch?v=4ikvea42XCU Here's what they did for Ghost-types]]. It starts out okay, if a smidge ominous due to the Lavender Town theme...then it gets terrifying. The song slowly gets more and more distorted as various Ghost-types are shown attacking and sometimes ''killing'' humans (or just sneaking up on them) and it eventually seems to end with [[TearJerker Cubone and his mother]]...but then a Gengar shows up. After the Gengar, we see a Banette--a ''[[TheFourthWallWillNotProtectYou live-action]]'' Banette--get up and chase the viewer. And then, [[{{Satan}} Giratina]] emerges, gains a shadowy SlasherSmile and looms over the screen as the music gets more distorted...then, Giratina's wings envelope the screen and the song glitches to a halt.
** Somehow, [[https://www.youtube.com/watch?v=25T5U-Q_D2Y the one for Psychic-types]] is even worse. Like with the above mentioned video, it mostly just focuses on the Pokemon that make up this particular type, but they're showcased in terrifying ways. Ironically, the memetically creepy Mr. Mime only gets a cameo and is relatively tame. From there, we get such lovely gems as a pair of Meowstic who look like the [[CreepyTwins twins]] from ''Film/TheShining'', a Creator/{{Tim Burton}}-esque depiction of Gothorita luring a boy out of his bed to play with her, a Gothitelle [[TearJerker crying]] as she has a vision about a man (presumably her trainer) [[AdultFear growing old and dying]], Solrock and Lunatone doing...''something'', a brief close-up on a bouncing Spoink's heart (with the strong implication that it's ''about to stop beating'') and Jynx...oh sweet Arceus above, ''[[NightmareFace Jynx]]''...it's all peppered by a series of images that seem to be about Sabrina slowly going insane and eventually culminates in [[UltimateLifeform Mewtwo's]] creation and the birth of [[EldritchAbomination Deoxys]].
