Glitch Pokémon are Pokémon that manifest through errors in the game's programming. The stuff they do to your file is all kinds of messed up. Perception through the reality of the game can result in plenty of Fridge Horror.
Many players don't ever want to surf up and down the eastern shores of Cinnabar Island or Seafoam Island in any version of Pokémon, due to the glitch "MissingNo." and its "twin" 'M from Pokemon Red And Blue, who on top of looking like garbled towers of pixels, had the potential to corrupt one's graphics, and, as well as an erroneous belief that they can corrupt your save. The battle music slows down or drops tracks. The text also becomes screwed up because these Pokémon have moves whose names seem to go on forever (or really weird names like "TM20").
Also unsettling is the Glitch City, a garbled mess of pixels which, if traveled into too far, will cause the screen to freak out and the game to freeze.
You can also get a different version of MissingNo in Pokémon Yellow, where encountering it becomes a lot more screwy. The aforementioned "perception through the reality of the game" results in the protagonist essentially walking around in the grass with the Pikachu that Professor Oak just gave him, dreaming about becoming a Pokémon Master, when suddenly he's attacked by a wild Pokémon and everything glitches out. After some screwed up noises, the game freezes.
Another Yellow glitch with a similar effect to the Yellow Missing No. is "Female Symbol", whose name isjust the symbol for "female". Just like the above scenario, except this time the Eldritch Abomination screams at the player, freezes the game and kick-starts a creepy remix of what appear to be multiple different musical tracks from Lavender Town, the Team Rocket hideout, and other places in RBY with creepy/scary music. Have a listen. Hell, even Female Symbol's sprite may be one of the creepiest things in the series, as it really does look something like a dimly lit Lovecraftian horror.
The worst part is how much it looks like Earthbound's final boss.◊
For a 10-year-old trainer (as in, the in-game character), finding himself in Glitch City would be horrifying by itself; however, as the player stares at it more and more, it becomes obvious that the whole place simply should not be. To escape you must Fly, Dig, Teleport, or fall in battle.
Missingno's stats imply he's almost as tall as Wailord (the biggest one), and heavier than Groudon (the heaviest one). However, this is the result of a mistranslation; in the Japanese version of Pokemon Blue, where Missingno. has a filler Pokedex entry, its height and weight are a much more reasonable 1 meter and 10 kilograms.
In Crystal (not Gold or Silver, since glitches are different there, like in case of Red/Blue and Yellow), Glitch Egg weighs even more, at 6146.5lbs (~2788kg; also about 300% of Groudon weight). Too bad it's remarkably small for its mass, at only 22 inches (55.88cm; technically should be foot and 10 inches, but game wrote it as 22 inches), making about 146 (147 with forme) real Pokémon smaller than it, most of them are at basic stage however.
Makes sense if you think of Glitch Pokémon as Eldritch Abominations from other dimensions where matter may be different, or at least cosmic (matter present at the core of a star can be so dense that a pin-sized chunk outweighs battleships).
Meeting not just Missingno and Pokémon over level 100, but glitched trainers as well (if one used grammatic symbols in the 3rd, 5th, or 7th part of their name) is another freaky experience. Example: a Channeller outside Cinnabar Island whose Pokémon were a mess of glitched names and graphics. The Pokémon also glitched the background music into a never-ending stream of randomly distorted sound effects. Also, the glitched trainers neither said anything nor rewarded money when defeated.
Missing No's most famous appearance that M' also takes is a bunch of pixels shaped like a backwards L. More people are scared by what a glitch Pokémon does than by what it looks like, but Missingno occasionally takes the shape of a Lavender Town ghost (Gastly and Haunter sans Silph Scope), a hollow shell of a Kabutops that hasn't been revived, or the skeleton of an Aerodactyl that hasn't been revived.
M', if it's level 0, and you send it to your PC, it destroys everything the trainer knows and loves just by existing (more specifically, by corrupting the PC and making it inaccessible).
The dead static that serves as 'battle music' for the Yellow Missingno.
4.4 is a Glitch Pokémon who initiates battle with the Critical Annoyance low health siren. Said music begins as soon as the Wild Pokémon Battle music starts and doesn't stop until the Pokémon appears, where it's replaced with a discordant glitchy sound that sounds like a mix of another Pokémon's cry and a telephone ringing. The glitch then goes very quiet and freezes the game. It can also cause the player character to disappear with clones of him through the air, apparently.
Hacking the life out of a older game can cause it to retaliate. When cheats are forced upon the game, it can still works until players "cross the line" and get to Pallet Town: then the screen freaks out alongside everything else until it turns into a pattern of white and black stripes.
The Glitch Pokémon named h POKe. It is harmless by itself, but what is creepy is its height and weight: a mess of garbled pixels, over 80 feet tall and 3 tons heavy. The garbled pixels are a result of the game trying to display more digits than it can display, meaning it's even bigger than that.
3TrainerPOKe in Pokémon Yellow Version, which amongst other things can really mess up the appearance of the player's◊ Pikachu◊.
There is one glitch in Generation 4 where when using the walk-through-walls with Action Replay and walk up through the Elite 4 blackness: this eventually results in the player arriving at Floarama Meadows. Trying to backtrack result in the player eternally stuck in the Elite Four door.
Third Gen (Ruby/Sapphire/Emerald) has the Bad Egg, which may be the game punishing the player for cheating. To elaborate, its a glitched Pokémon egg that shows up when one uses a Gameshark or otherwise screws with the game's data, and can either be benign and simply appear in an encounter as a "Not recorded yet" Pokédex question mark with the name ??? and caught as a bad egg, or turn one of your Pokémon in your current party into one that can not be removed, or worse, replace the first Pokémon in your active box with an egg (as well as any others you try to replace it with). When hatching, Bad Egg can actually erase the player's save file (maybe as a Shout-Out to the cruel Copy Protection in EarthBound), or sometimes, the glitch Pokémon does so without hatching at all.
A similar, but different, glitch from Generation II is the Glitch Egg. Acquired from doing the Celebi egg glitch improperly, the Glitch Egg appears to be nothing more than a normal egg; however, it hatches into another egg. And will continue an indefinite cycle of hatching into another egg forever. While Glitch Egg itself is harmless (other than hatching into itself and having a badly garbled Pokédex entry), it can be quite horrific for a player attempting the Celebi egg glitch, as the only way to truly know if the glitch was successful is for the egg to hatch, potentially rendering all their effort for naught.
In Pokémon X and Y, we get a lovely crossbreed of a Bad Egg and 'M: the Mystery Egg. Like the regular Bad Egg, Mystery Egg doesn't hatch. It was apparently laid at 0/0/0000. The Mystery Egg, like a Lv. 0 'M, corrupts the box it's in, taking all the Pokemon in there with it.
The ZZAZZ glitch. It gets rid of the in-battle music and replaces the cries with late-arriving, grating noises. It also changes the player's name to ZZDZZAZZ4ZZ Z ZIZZ9ZZ[box]ZZ. In addition, it makes the sprites of almost anything become garbage, and almost anything players do makes their Pokémon explode.
Thanks to a certain glitch, the real reason why trainers need Pokémon before going into the tall grass is revealed: this is why.◊ Based on the picture, a headless Pidgeotto attacks and morphs the player character itself into a shapeless mass of pixels, taking the interface with it.
A few glitch Pokémon have stats high enough to make even Arceus's pale in insignificance. To put that in perspective, Arceus is the Pokémon equivalent of God himself.
One of those is the terrifyingly powerful PokéWTrainer, which effectively has a 924 stat total. (Arceus has 720, so even if Arceus were to gain a Mega Evolution it would still not reach PokéWTrainer). It's not lacking in STAB moves to abuse it with, either.
There is a glitchy creature in Pokemon Red and Blue that looks like Charizard, but behaves like a horrifying glitch. Because of this, it has earned the nickname "Charizard 'M", often referred to as "The Final Boss of Pokemon". It was discovered that its in-game data matches that of the "cancel" button. That's right - that means it cancels everything it comes into contact with. If you store it in the PC, all your Pokemon will disappear. If you talk to Nurse Joy, the conversation will immediately end so you can't heal your Pokemon. It's nothing short of the embodiment of nothingness. If that weren't enough, battling it results in the TM Trainer effect, and it has 65,535 hit points, so there is no way that the player could actually beat it. And to really drive the point home, it has the same index number as the aforementioned ZZAZZ — the game can't start a Trainer battle within a Trainer battle, so it corrupts data that is already corrupt.
It gets worse from there. If you manage to get one of these abominations(which can be done by trading another glitch Pokémon, Qnote Which is a fairly easy-to-get glitch in Pokemon Yellow, but also qualifies as Nightmare Fuel due to being Yellow's version of the glitchy cancel button and ZZAZZ, to Red and Blue), don't let it fight or put it in an occupied PC box. Otherwise, the Charizard 'M will turn your Pokémon into even more Charizard 'Ms.
The Misery of Orre
The region of Orre from Pokémon Colosseum gets its own folder thanks to mad scientists that enjoy corrupting Pokémon, a barren wasteland, and thugs galore.
Orre is a Crapsack World compared to other regions, including Sinnoh and Team Galactic who attacked it. A region-wide Pokémon equivalent to Gotham City, which is saying something. See below.
Orre itself seems to be a rather darker setting than the other Pokémon games. Most of it is a desert wasteland, save for one little grove of trees that Celebi's power presumably keeps green. The wastes cut off a little further west in XD, but still, Fridge Horror kicks in when wondering how the rest of the region got that way.
Added on top of that, there's the little fact that things are so bad that not even wild Pokémon live there. Y'know, the creatures you've come to know and love that are widespread throughout every other region? It's remedied a little in XD with a few places where wild Pokémon can possibly appear, but still.
Phenac City, with Colosseum'sBig Bad Evice as its mayor. The fact that the chief of the biggest crime syndicate in Orre is running the city should give anyone nightmares, but XD manages to top that with not just the mayor, but nearly everyone in town - the real civilians are locked below the Gym, the Gym Leader included - being a Cipher agent in disguise.
The deserted cruiser S.S. Libra in XD, with no music but the sound of the wind and the sand pelting against the outside of the ship...
Also, how a ship got out in the middle of the desert in the first place - the Pokémon onboard were jacked by Cipher while the ship itself was being psychically carried by XD001. This time the syndicate doesn't fool around: they beach a ship as a weapons test.
They weren't even trying to beach the ship - they wanted it brought intact to their base so they could Mind Rape all the Pokémon inside. Lugia somehow wound up dropping the ship. Imagine being carried through the air on a terrifying voyage, only for gravity to suddenly reassert itself and send you hurtling to your doom.
Lugia dropped it there on purpose so Cipher could capture the Pokémon (but never found Bonsly) inside. But in the beginning, you can see two crewmen get thrown overboard as Cipher steals the ship. They're reported missing, but never found.
Cipher. "Seal the hearts of Pokémon" may be cheesy for an Evil Plan, but the real horror is what it implies - they Mind Rape a Pokémon by stripping it of all sense of compassion, emotion, and empathy, leaving nothing but a soulless, heartless killing machine behind. Any remotely "scary" Pokémon becomes suddenly even worse, much worse. It's also a Deadly Upgrade in XD, thanks to the Pokémon refusing to receive items from the trainer and sustaining damage at the end of each and every turn of the battle (when in Reverse Mode at least.) Not even Pokémon Centers can do anything about Shadow Pokémon other than healing them.
The Mind Rape can also be seen as an unnervingly accurate metaphor for real-life cases of shock and self-injury stemming from abuse or trauma. Multiple continuities show Pokémon having personalities similar to young children, especially Togepi who is said to share its happiness with others: this doesn't keep an ex-R&D Hordel in XD from giving players a Shadow Togepi with a request of purifying it.
It also is highly disturbing when one realizes that Shadow Pokemon include such peaceful, naturally kind creatures such as Miltank, Chansey, and Kangaskhan. The idea of them being turned into horrible, heartless monsters is not something one wants to comprehend
Another thing to consider. Pokémon Colosseum was released in the early 2000s. Pokemon Black And White was released 2010-2011. Cipher was the undisputed bottom of the morality barrel for nearly a decade, and even with Ghetsis showing up, all that's changed is the "undisputed". And not even Ghetsis has dared to challenge their title as the patron saints of Paranoia Fuel.
The actual owners of Shadow Pokémon fall into four categories - people who want to set them right (Wes, Rui, and Michael), people who don't know the bum deal they got, people who want them for their power, and the members of Cipher. Ranks in said organization are typically indicated by how many Shadow Pokémon the members possess - lowly grunts typically have one or two, with higher-ups having up to four. Greevil has a grand total of seven, four of which are legendaries, and one of which (XD001, that is, Shadow Lugia) is so thoroughly corrupted that its physical appearance even changed to reflect this. Considering Cipher is one of those Names to Run Away From Really Fast, it's easy to see how the whole group beats out Cyrus in terms of sheer evil.
Nascour◊. His white hair is Medusa-like, he wears a skirt along with his uniform, and he was toting the red iris/black sclera look before Master Albert on top of that. He's essentially the face of Cipher in Colosseum (Evice, aka Es Cade, is the real boss, but Nascour runs things overtly to keep heat off him). He also promises, before your fight with him, to show you "the humiliation of total domination" before the spectators at the Realgam Colosseum.
Also, when fighting him there is no music at all. All that can be heard is the crowd chanting "BATTLE! BATTLE! BATTLE!" endlessly. Every time you faint his Pokémon, they boo as one voice; every time the player's party suffers a defeat, they all cheer for him. Basically, the definition of Villain with Good Publicity taken to a ridiculous extreme.
His theme sounds like the general villain overture, only this guy has a background of cheering fans to go with it. The chants even sound like they're shouting "Kill!" over and over again. He's Obviously Evil, and yet everyone loves him...
In Pokémon XD, there is a video where Dr. Kaminko's eager assistant Chobin details the inventor's creations. While some of these inventions are either completely useless, such as light bulbs that consume ten times as much power, there is one particular invention called the "Haunted Radio". Works like a normal radio, except when tuning in at 2 a.m. and listen very closely, you are said to be able to hear a tiny voice moaning "Please help meeeeeeeee." However, it's just a joke of the professor's.
The Ceiling Peon is the last thing players need when their team is on its last legs. Struggling through some abandoned complex looking for a healing machine, and a Peon drops right in front of trainers, pulls out his Pokémon, and wipes theirs out. Unlike the other teams, Cipher employs Ceiling Peons regularly in all of its installations. Taking this even further, one Ceiling Peon ambushes the player on the elevator during the ONBS raid.
Here's a list of some Shadow Pokémon owned by Cipher's higher-ups: Raikou, Entei, Suicune, Zapdos, Moltres, Articuno, Lugia, Dragonite, Tyranitar, Salamence, Metagross. 7 Legendaries and 4 "semi-legendaries". Cipher was able to not only CAPTURE what equates to gods and demi-gods (something any Pokémon player knows is not easy), but also corrupt them.
Since Cipher uses Team Snagem to capture Pokémon for them, and before he quit, Wes was known as one of the best they had, there's a good chance he's partly responsible for the Mind Rape of those Pokémon. Not to mention all the destruction they've caused.
Ardos is one of the big reasons the people of Orre have trouble sleeping at night.
He set a record for his time as to how low a villain will stoop to deal with the player trainer — whereas the leaders of Teams Rocket, Magma, and Aqua all ceded when their plans tanked, he suggested to Big Bad Greevil that they take off and detonate Citadark Isle with you on it! He advised mass murder (the Peons still on Citadark are apparently expendable) as a way of dealing with you. Only Ghetsis would even get close to this level of depravity.
The Orre Colosseum has rematches against the Cipher Admins, and all of them give out titles when you defeat them. Ardos' is "Cipher's Biggest Enemy" — and the message bearing that title basically amounts to a death threat!
Ardos also vows to rebuild Cipher after Greevil gets vanned, and this is after the group's second collapse. Considering that only Team Rocket and Team Plasma ever managed a second attempt, and Team Rocket ceded for good after its second fall, this means Cipher's going for round three, and very well could make good on that threat.
Cipher's last appearance was back in Generation III. Who knows what havoc they could wreak if they manage to make Shadow Pokémon out of stuff like Hydreigon, Haxorus, Chandelurenote already has a reputation for burning people's souls, Darkrai, Heatrannote the embodiment of volcanoes — which means they might use it to bury towns under magma flows, or, Heaven forbid, Arceus?!? Or any of the other nightmarish Pokémon mentioned further down the page?
Gen VI gives us such pleasantries as the aforementioned Phantump; its evolved form Trevenant; Honedge, a possessed sword that can drink the life force of others; Clawitzer, the "BFG Shrimp" Pokemon; and mental manipulator Malamar. Shadowing any of those is bad enough, and that's not even going into Mega Evolution. On top of that, Yveltal can desoul entire towns, Primal Kyogre can wash Orre away, and Primal Groudon can melt it to the consistency of glass; giving those latter three to the likes of Cipher equates to handing the worst people in the world a WMD and the carte blanche to use it. Sweet dreams.
Pokémon are often fighting in battles for their trainers, but players can forget how painful being at the receiving end of an attack can be just as often.
Curse, Ghost-specific version: it involves the user shoving a nail, slowly, into its own face, then doing the same thing to its opponent.
Mean Look: erratically blinking eyes in Generation II, Giant Eye Of Doom in Generation IV. Either way, it makes you too scared to move.
Screech: a screech that's actually more of a chime from Generation III onwards, but relies on scary sounds in Generations I and II.
Dark Void: a move that (supposedly) puts the opponent to sleep forever, when combined with Darkrai's ability to cause nightmares accidentally. Also, the animation◊ is scary on its own, with the opponent being slowly dragged in the titular void.
Any one-hit-KO move: being sliced in half (Guillotine), frozen to death (Sheer Cold), being drilled into (Horn Drill), and being hurled into a near-endless abyss (Fissure).
Crunch: a more powerful version of the Dark-type Bite attack. Its attack animation in Gen II has the screen turning dark, and a massive pair of jaws gnashes down on the Pokémon with tremendous force.
Pokemon Stadium takes most moves Up to Eleven: Horn Drill's animation is a giant drill on a black background, and if it connects, the screen and the hit Pokémon flash blood red.
Stadium's description of Lovely Kiss notes in brackets that the target actually passes out/faints, depending on which one you use.
Leech Seed: innumerable seeds burrow themselves into the opponent, and before the victim can brush them off, they sprout and suck the target's life force.
Perish Song: three turns after the move is used, both contestants faint unless either one is swapped. This is accompanied with an animation meant to represent a Last Note Nightmare.
Nightmare: it damages sleeping Pokémon through a smiling winged demon.
Destiny Bond: This attack is what happens when "If I die, I'm Taking You with Me" is actually more than just an empty threat, especially when coupled with Mean Look or any other move where you can't switch your Pokemon out.
Extrasensory: it basically overloads the brain functions of the target by giving the other Pokémon a sense they're incompatible with.
Some Psychic attacks can realistically be considered Mind Rape. Dream Eater is the best example. Others use telekinesis (Confusion, Psychic), which is slightly tamer, but the idea of throwing a helpless opponent around with the power of one's mind alone is terrifying enough of its own, as any horror movie involving Psychic Powers will be happy to remind you.
Sludge Wave: Imagine a tidal wave, itself a terrifying sight and frightful experience, strong enough to crush bones even as it swallows a victim and drowns them in its roaring depths. Now imagine that the wave isn't water, but poisonous chemicals, corrosive fluids, and liquid pollution. That's Sludge Wave.
Scald: burns the opponent with searing water.
Shell Smash: shatters its own shell for a power boost.
Sky Drop: grabs the opponent, flies upwards, and drops them.
Guillotine: a vicious, tearing attack with pincers. The foe will faint instantly if this attack hits.
Final Gambit: the user loses all of its of HP, and the foe takes an equal amount of damage.
Metronome: uses a random attack, which includes any of the moves described here.
Inferno: a massive Zap Cannon-ish fire attack that always burns.
Horn Leech: pierces the foe with a wooden antler and sucks them dry. And that sound effect...
Glaciate: signature move of Kyurem, whose dex entries state that it harnesses amazing ice powers. The move freezes it alive. It does not help matters that Ghetsis attempted to freeze the Player Character with this move, which comes off as outright impalement compared to freezing.
Icicle Crash: impales the opponent with a giant icicle.
Spacial Rend: signature move of Palkia. It rips apart the literal space around the target as an attack.
Roar of Time: signature move of Dialga that "distorts even time". The most common explanation for how this works is to make time move at different rates for different part of the target's body. Imagine your heart suddenly becoming 1000 years old and crumbling into dust, while your brain spontaneously reverts to the stage of an infant.
Shadow Force: whereas the other two signature moves of the Creation Trio invoke Body Horror, this one is all about the Paranoia Fuel. Imagine if you will that you're a Pokémon locked in battle against Giratina, when suddenly your foe just vanishes into thin air. You panic and start frantically looking around trying to find it, and then it appears from behind you and mangles you, and there's not much you can do about it — Protect won't save you from this one.
Crush Grip: gets stronger the more health the target has. This implies that it squeezes the life out of the opponent while it tries to escape.
Struggle: only used when a Pokémon has no more options left and can only helplessly flail around in full panic mode. In-game reason: this only happens when your Pokémon runs out of all of its points for all four attacks it has.
Night Slash. The move itself isn't the problem, it's where its name comes from. The English name of the move still alludes to this, though it's not as explicit as the Japanese version.
Autotomize, or as it's called in Japan, 'Body Purge'. It refers to autotomy, the ability of certain animals to deliberately shed parts of their own body, usually to escape from a predator. The Pokemon is literally ripping/tearing/slicing/whatever parts of their body off in order to move faster.
Power Whip: A mass of vines or tentacles violently lashing out. Its animation in Gen VI depicts the vines/tentacles brutally ravaging the silhouetted target.
An odd one. The signature move of Helioptile is Parabolic Charge. It basically acts as an electric type Absorb... except from everyone surrounding it. Now then, hypothetically speaking, every single living thing has electricity in their bodies, through some sort of... electromagnetic... pulse... Or whatever. Basically, everything has electricity to allow it to function. It's what sends messages to the brain about what's happening in the body. It's even how the mind itself works. This might mean that, well you're sucking the electricity out of the opponent. You're sucking what allows them to function out of them.
There is Yveltal's signature move Oblivion Wing. It flies into the air and drops a beam onto the opponent that deals massive damage to them while restoring more than half of the damage dealt back to its own HP. If that's not bad enough, Yveltal's backstory mentions how it absorbs the lives of every thing around it to extend its own life; hell, its Japanese name is "Death Wing". Yveltal is essentially killing its opponent and absorbing its life force into itself. And to make matters even worse, it bears a striking resemblance to a Reaper'sWave Motion Gun.
Punishment, a move that deals increasing damage based on the amount of times the target has boosted its stats. The name, the Dark typing, and the fact that the animation looks like a scythe-like guillotine tearing into the target from above make it a bit unsettling.
Meta-example, and downplayed: Expecting the CPU opponent's Pokémon to lose miserably to you, due to type-advantage, only for them to attack you with a super-effective move from a TM, breeding, a move tutor, or even cheating. Especially distressing if said move was 4x effective, and/or OHKO-ed your Pokémon.
Every game has them to some extent, whether they're in-universe (canon) or based on the games.
The Desert Resort in Black and White has Yamask inside: those are Pokémon based off of Egyptian souls combined with death masks. The White Dex Entry states "These Pokémon arose from the spirits of people interred in graves in past ages. Each retains memories of its former life." A Pokémon from the spirits of the dead, in a wrecked tower. Alternatively, the Black dex entry states "They look at their mask and cry". Apparently, the mask is an exact replica of that person's face when they were human
In Black and White, there is a bridge that lies in between Route 16 and 15 called Marvelous Bridge. At the end, a man and a woman can be seen. When talking to the woman, she will disappear before the player's eyes. The man beside her is just as shocked as players are.
That's nothing compared to what happens in the sequels. For instance, we find out who this girl is, and what her story is: In one of the new areas, you find an abandoned house, and as you go through the various levels, you find furniture rearranged when you weren't looking. Once you near the end, you catch a glimpse of the girl from the bridge, crying out for her mother, father, and her Pokémon. Then, you enter the final room, and find the Lunar Wing... upon which the girl reveals she's been protecting it. The description says the house was the victim of a strange and sad accident... What the hell happened here?!
A bit of thought may shed a possible answer to that. The Lunar Wing that you find is used to call the Pokémon Cresselia, which is the only Pokémon known to counteract the effects of the Pokémon Darkrai's nightmare-inducing abilities. Now, knowing that about Darkrai and judging by how hell-bent this girl is on protecting the Lunar Wing, as well as her dialogue about being in an "endless dark dream" calling for her family, it's implied she fell victim to Darkrai and the Lunar Wing wasn't brought to her in time — and as such, she either ultimately died in her sleep or her parents may have taken extreme measuresto end her misery. Again none of this is confirmed, but still a chilling thought.
Additionally, in Black and White 2, she reveals that the reason why she was haunting the Marvelous Bridge was so that she could get Cresselia's attention and return the Lunar Wing, because she knew it could no longer help her. But that's not the chilling part. She also states that in the dark dream, she could hear her dad's voice saying "Forget about the Lunar Wing..." Now, normally, Darkrai's (literal) Nightmare Fuel abilities are seen as a defense mechanism, and most people believe that it doesn't actually mean to cause harm. However, the girl's statement seems to suggest that this particular Darkrai actually wanted her to stay trapped in the dark dream, perhaps because it was lonely, OR because it had more... malicious ends in mind.
The B2/W2 guide book confirms that she died in her sleep from her dark dream.
In Black and White, the Litwick/Lampent/Chandelure evolutionary line sucks out people's souls.
Oh, they don't just suck out the soul; that'd be too simple. Chandelure sucks out the soul, and BURNS it!
Black and White 2 expand on this: Litwick's flame is only lit when it is absorbing souls. It's always lit when you view it. We could have done without that dex entry, Game Freak!
There's a little girl in the Celestial Tower with a Litwick. If you talk to her after battling her, she says that whenever she sends her Litwick out, she immediately feels really tired — implying that this 5-year-old little girl is being slowly killed by her own Pokémon, and she has no idea that that's what's happening to her.
Some of the Pokédex entries mention that Chandelure "leaves the body behind." But it doesn't say anything about whether or not they die. Your body can still function without a soul, but Chandelure rips out your soul and just leaves your empty body to wither. That's right; Chandelure is the Pokémon equivalent of a dementor!
A NPC in Lavender Town in Red/Blue and Yellow Versions provides the following exchange just to screw with players:
"Do you believe in ghosts?"
"Haha, I guess not. That white hand on your shoulder, it's not real."
Lavender Town's Pokémon Tower in the original Pokémon games was a creepy tower full of ghosts that your own Pokémon - without exceptions - were afraid to battle. The music was scary as well, and old channellers shout creepy things at players when they engage them in a Pokémon match (because they're possessed by their own Pokémon). There are very good reasons that most Pokémon Creepy Pasta centers around this place.
"Give me blood!"
The ghosts themselves without the Silph Scope: in the remakes, they look misty, but the originals are quite creepy, as well as one of Missing No's forms.
The music was also was VERY creepy, being in a stark contrast to all the upbeat and happy music of the rest of the game.
The battle with the rival on the S.S. Anne? He had a Raticate. Players' next bump into him is in the Pokémon Tower, this time without a Raticate; he is seen staring at a lone grave stone. And he questions "why you're even here" when none of your Pokémon are dead. The implications speak for themselves.
In order to catch Rotom, players must go there at real-time night. The fact it comes out of a haunted television may count as a Shout-Out to The Ring.
Escape Ropes do not work in the Old Chateau. Lost explorers can only get out by themselves.
In Diamond/Pearl/Platinum, when heading up Route 217 to Snowpoint City, there's an old woman sitting alone in her cabin with all the lights off, telling trainers about the lack of visitors. After giving trainers the Spell Tag - a Ghost-type enhancing item - she's not there anymore when the house is accessed again. A trainer that's near the cabin actually mentions legends of hauntings in the area.
Although it's not a straight haunting, at the Ruins of Alph in the HG/SS remakes, if the player talks to his party members, they'll remark the place is freaking them out.
The same thing happens when you're inside Mt. Silver: the player's Pokémon suddenly freak out and howl, and occasionally "sense something" and nervously call out. Also, most of the mountain, the route leading up to it, and the Pokémon Center at its base are totally devoid of trainers. * Except for Bonus Boss Red, whose Heroic Mime status and training-alone thing just makes things worse.
The Old Mansion in the third Pokémon Ranger game has plates that float up and launch themselves at the player.
Giratina's place in Diamond/Pearl. Unlike the equally scary Distortion World from Platinum, D/P things are a little closer to reality: Giratina lies in a hidden cave, called Turnback Cave, where supposedly the reality boundaries are distorted, and "dead Pokémon can come back to this world". It's literally the door to afterlife. The cave is hidden in a quiet forest, the "Sendoff Spring"; the creepy "Old Chateau" themestarts playing, giving the feeling that it's not a good idea to stay in the spring; and for good measure, the Japanese name for that place is "Funeral Spring Path", further implying that's where people's ashes are thrown.
It's still there in Platinum, and you can still enter it. In fact, you and Cynthia appear in front of there when you leave the Distortion World. So now we have two equally creepy locations connected to the same Pokémon, both accessible in Platinum, which makes you wonder if Turnback Cave is just an extension of the Distortion World.
It gets even more creepy when you consider that, upon arriving in the Turnback Cave via the Distortion world, Cynthia ponders how Turnback Cave is said to be the entrance to the afterlife. Which would imply that that creepy, Eldrich Location you just left is...
And it also says that Giratina was banished to the Distortion World for bad behavior. If the Distortion World is the afterlife, then that means Arceus actually killed Giratina for his bad behavior, and sent his spirit to the Distortion World.
Might be even worse than that. Giratina was banned to Distortion World for his behavior, by Arceus. Arceus is God. What other figure was banished when it caused trouble to God...? He also had all his limbs removed and became a serpent after his banishment from Heaven. In the Pokémon world, Giratina's "Altered Form" has legs, while his "Origin Form" doesn't. Giratina's "Origin Form" also has a pair of very large horns. Lastly, both forms have six claws, six "ribs," and six spikes/legs.
If it's of any comfort, Giratina is more aggressive than downright evil. However, it becomes more terrifying when you realize that Giratina is essentially an Eldritch Abomination akin to that of Yog-Sothoth (Both being inter-dimensional god-like beings that can barely (if at all) be comprehended by humans). It rules a world consisting of anti-matter (something we as humans have very limited understanding of as it is), can shift between two forms (one a six-legged dragon and the other a serpentine-looking...thing), is able to attack by hiding in the shadows and emerging from them (IE: Shadow Force), and has an obsession with maintaning balance to the point where it will gladly drag anyone (Cyrus found out the hard way) down into an alternate world where our understanding of physics and reality as we know it are thrown out the window. Giratina isn't just scary, it's something that would fit right in an H.P. Lovecraft horror novel.
In any case, it's still a Pokémon, and you can capture it. Imagine how people will react when you send said Eldritch Abomination into battle.
One episode of the anime revolves around an evil ghost girl who hypnotizes unsuspecting people and tries to lure them into the Spirit World. First, she tries to lure Conway into going off of a cliff. Then she scares the daylights out of Meowth. Finally, she appears at the entrance to the Spirit World itself and tries to pull in Ash, Angie, Pikachu, and Shinx, and the only thing that saves them is Professor Rowan's arrival. And when Dusknoir defeats her with a Psychic attack, she screams horrifically as she gets blasted into shadow and dissolves. Imagine if she had succeeded in her plans — would you want to be one of their parents on the other end of the phone, being told your child is never going to come home?
In the north side of Lumiose City there's a building with three floors with children playing around on the first floor and the dojo leader from Kanto starting up a gym on the third. The second floor? As soon as your step out of the elevator the lights go nuts, you're unable to move and a ghostly woman just slowly moves around you before stating that "You're not the one." and leaves. Who is the one, and what would have happened if it were you?
There's more creepy and unexplained intricacies in Lumiose City than the mysterious ghost girl. If you enter Lumiose Station and read the timetable at the far back from behind, you'll find an unnerving message.
Something is written on the back of the timetable.
"I'm going to go for help. Wait in the usual place."
On the fourth floor of Hotel Richissime, speak to the girl in the room to the right of the elevator (who shares the same model as aforementioned ghost girl):
Girl: "...If you do, I won't... ...hear the elevator..."
The Electric Tale of Pikachu gives us the Black Fog◊, a gigantic and ancient Haunter that was once worshipped as a god. Nowadays, it's taken to indiscriminately killing both people and Pokémon by devouring their souls. In the end, rather than being caught by Ash while severely weakened, it graphically committed suicide with Selfdestruct.
After the Delta Episode in ORAS, when you get to Room 4 in Sea Mauville, you will hear of a presence like you're being watched. If you check the top left bookcase, you will learn that the Odd Keystone was lost on Sea Mauville, and then get another note about being watched. Then, if you select a menu option such as Items, Pokédex etc., and then exit, the Odd Keystone will be behind you and Spiritomb will attack.
Every game or show worth its salt has music with that proper feeling: Pokémon has plenty of Awesome Music, but sadly part of that awesomeness is devoted to convey fear.
The Lavender Town music in the original game was really creepy. It got toned down and sounded almost touching in some of the later games, but it didn't stop fan remixes from cranking the scary aspect Up to Eleven.
The music played during the fight with Arceus in Diamond and Pearl is a mess of dissonance and thunderous MIDI-timpani. Fitting the situation, as Arceus is the Pokémon equivalent of God.
This music is reused in HeartGold/SoulSilver in an event involving Arceus creating an egg containing either Dialga, Palkia, or Giratina for the player. It's combined with strange geometric shapes and backgrounds made of actual photographs of the real world.
Arceus has a different theme in Pokémon Ranger Guardian Signs. It's just as eerie and appropriate for battling God, but in a different way. It sounds like depressing, melancholic church music, and several commenters aptly describe it as a theme song for an apocalypse. Instead of riling you up for battle, this theme is telling you, "you have already lost and there's nothing at all you can do about it."
The Hall of Origin itself is designed to creep players out given the place's ridiculousheight and the eerie music, which is the title screen music, backwards.
The music from the Silph Co. building in the original Pokémon games, which has been taken over by Team Rocket.
In HeartGold and SoulSilver, most of the scarier themes have been toned down. However, the GB Sounds item will change the music back to its original 8-bit form, restoring the creepiness.
The music that plays when meeting the legendary birds in Platinum (Articuno, Zapdos and Moltres) is made unexpectedly disturbing by the fact they're roaming Pokémon in that game, and as such, they can appearanytime.
The Crystal legendary beast BGM. This song would be okay for the scripted event battle against Suicune, but not against against the roaming (read: randomly-appearing) Raikou and Entei.
The drought section in Pokémon Ruby, when Maxie disturbs Groudon and the sun's rays are magnified to a dangerous level. All the music that plays in outdoor areas (including the happy, upbeat surfing and bike riding sounds) is replaced with a morbid and minimalistic track. Coupled with the pulsating bright lighting, the effect is unpleasant.
In Sapphire, during that part the world begins to continually rain. In Sootopolis, everyone is inside their houses cowering, which makes sense as Sootopolis is pretty much a giant secluded basin about going to flood and drowning everyone in it. The moment where the Aqua leader goes "My God, What Have I Done?", the music that starts is one of the scariest things in any video game.
Emerald combines the best of both worlds because both teams wake up their mascots simultaneously: it goes back and forth between pulsing heat rays and flooding.
This creepy theme is also used for the inside of Shoal Cave (north of Mossdeep City,) causing the otherwise not-scary-in-the-slightest cave to take on a decidedly creepy atmosphere.
The third Pokémon Ranger game has an in-universe example; there was a song that was banned for being too scary for kids, talking about black clouds and lightning. Bonus points for the book containing it being found in a haunted mansion.
This unused Pokémon track from Pokémon Yellow, said to have meant to be used during a scene where players walk into the grass before getting their first Pokémon, and doing anything but run results in the message "Hurry, get away!"
The music used for the Distortion World really does capture the very separate-from-reality type of feel that the Distortion World (Or "Torn World" for the Japanese) is supposed to have. Despite being creepy in it's own right, it's also... eerily beautiful. Tranquil, even.
When you switch from Spear Pillar's music to Distortion World's upon arrival, you get the eerie feeling that reality just crashed right there.
The music used in the Old Chateau (among other places) in the Diamond and Pearl games is downright creepy: it has everything - including the mandatory piano - to fit the Haunted Mansion it plays in.
Considering how cute the Emotion trio from Diamond/Pearl are, their battle theme is surprisingly creepy.
That sound you hear in the song is technically Ghetsis' name. His name was made from that chord you hear- "G-cis".
Years after the release of Pokemon Red And Blue, an incomplete, unused track has been found in the game's coding. Although it sounds like it could have potential as an actual song (with fanmade restorations of it indicating such), the track almost seems like it could rival the Lavender Town theme in terms of creepiness. Listen to it in this video.
Black 2 / White 2 lets us revisit Team Plasma's castle which is located under Victory Road and almost completely in ruins. Of course, this also includes N's room, and while this has always been something to send shivers down the spines of several players, we are now greeted by this wonderfulremix of N's musicbox version theme. The key is off, you can clearly hear the musicbox not running smoothly anymore, and all in all, it fits to a room that is as devasted as the rest of the castle, complete with no lights, N's toys scattered everywhere. Brrr...
The music that plays after Opelucid City is frozen by Team Plasma in Black 2/White 2. To make this music seem even more depressing/disturbing is by imagining how many innocent people had probably died from that.
The Strange House. Not only does the furniture move as you traverse the building, the music that plays during it makes things very uncomfortable. It does not help when you learn about the vanishing girl on Marvelous Bridge from Black and White at the end of the maze.
Word to the wise, never go through the Strange House on max volume when you're home alone at night.
The Pokédex acts like a real world wiki: as such, there are some pretty scary things in there. It is worth noting that many of the entries are based on In-Universe rumours and stories, and thus should be taken with a grain of Shoal Salt.
Porygon-Z. It's a glitched version of Porygon2 evolved using a mysterious disc that was not approved by Silph Co., as a jarring metaphor for software piracy: "Porygon-Z can sometimes be seen shaking rapidly for a short time. Whether this is intentional or a glitch is unknown.".
Cacturne. It's a four-foot-tall-desert-crawling-cactus-turned-scarecrow that apparently stalks travellers (not Pokémon, not people, just "travellers") until they can no longer move, then it drains them dry.
It's also subtly implied that the whole "drains them dry" bit is preceded by a No-Holds-Barred Beatdown, so don't expect it to be quick or painless.
Banette, while creepy enough in appearance (a maliciously grinning, red-eyed, ghost-creature with a zipper for a mouth), are explained in the in-game Pokédex as being possessed dolls seeking revenge on the children that threw them away.
According to legend, Shedinja, which looks like a cicada skin, will steal the souls of those looking in its back. Too bad it's seen from the back when it's one belonging to the player.
Dusknoir is a huge cycloptic ghost with no legs, weird markings, and a rather haunting body, with a reputation of dragging people to the spirit world. The markings on its chest are actually a second mouth.
However, it is also said to guide lost spirits home. Furthermore, in its first anime appearance, it actually protected Ash and co. from being dragged into the ghost world.
Gengar, who appears at every full moon and scares people by pretending to be their shadow.
Haunter, in the manga, had a tendency to use its Dream Eater attack to steal people's souls.
When combined, Haunter's Pokedex entries imply he's an Eldritch Abomination slowly killing whoever it wants to kill.
Gastly. This adorably goofy-looking ghost head is cute, but also over four feet tall. And since it's made of gas, it can "sneak into any place it desires", according to several Pokédex entries, and can "envelop an opponent of any size and cause suffocation" as well.
Darkrai. The Pokémon that locks a small child in a perpetual nightmare until players find a MacGuffin. Its in-game ability is acting as literal Nightmare Fuel. However, Darkrai doesn't even do it on purpose.
To capture Darkrai, players must go into the previously locked Harbor Inn, where a 'hotel manager' says that he has been waiting for them, only to force them into a bed afterwards; the player character falls asleep, where he's transported to Newmoon Island. He or she will have to defeat or capture Darkrai to escape. When waking up, the man is nowhere to be seen, and out of the inn, a sailor will say to you that "you were asleep for a long time", and mention that no one's lived in that inn for 50 years.
Parasect, once a cute little Paras that becomes consumed and controlled by a fungus. The Pokédex entry says that in Parasect, the mushroom has grown so large that it literally sucks the nutrients from Paras' body to the point that it's stunted Paras' growth permanently. In other words, Paras is a larval stage insect, and Parasect is one as well. Only the mushroom has grown, making the timid Paras into a very aggressive, dead-eyed Parasect.
The Pokédex entry from Crystal is particularly creepy.
Pokédex: When nothing's left to extract from the bug, the mushrooms on its back leave spores on the bug's egg.
Mewtwo. He's essentially a genetically mutated feline created for the sole purpose of being used for Team Rocket's conquests. While all Mewtwo wants is to be left alone in peace, making him angry is still never a good idea.
The movies showed him using horrendously powerful telekinesis to all but murder everyone around him.
The games still have the implications, even if they don't outright say it like the movies do. Seeing the burnt out Pokémon Mansion and reading the journals of Mewtwo's birth (in which the scientists say they couldn't curb its viciousness) is enough to be creepy.
The Pokédex entries are none too reassuring. Putting them all together yields the picture that Mewtwo has been subjected to horrors and became violent as a result:
Red and Blue: It was created by a scientist after years of horrific gene splicing and DNA engineering experiments.
Emerald: [...] even though the scientific power of humans made its body, they failed to give it a warm heart.
Just to make your day worse, have you ever heard of Der Erlkönignote The elf-king or alder-king, depending on how far back your etymology goes? It's a poem by Goethe that depicts a father racing through the forest to get his sick child home; as they ride, the child relates how he's being tormented by the elf-king, which only he can see, and his father attempts to convince him he's only imagining things. When he gets home, however, the child dies nonetheless. To supplement this: the one time you ever fight a Hypno in the wild by way of story-event? It's the one preying on Lostelle in the Berry Forest.
Kadabra and Alakazam are said to have incredible intelligence and psychic abilities (more so with Alakazam) like telekinesis: nothing could stop them from doing whatever they want.
Pokédex entry: "It happened one morning - a boy with extrasensory powers awoke in bed transformed into Kadabra."
According to the old Red/Blue Pokédex entries, Alakazam's IQ is said to be 5,000 (compared to Stephen Hawking's 200-ish), and in Yellow, it states that Alakazam can memorize anything.
Alakazam is the embodiment of squishy wizard. It can't even move, having to telekinetically control his body parts. It could die just by having its muscles waste away.
Hitmonlee: Karate King of the Uncanny Valley, with mutated, short arms, no mouth or nose, just eyes that stare.
The Voltorbs and Electrodes disguised as item balls in the first-gen games. It should be noted that Voltorb and Electrode were only discovered after the creation of Poké Balls: their Pokédex entry for Ruby and Sapphire outright says they're Poké Balls that came to life.
Gorebyss: despite its beautiful looks, "it consumes its prey by sucking out the victim's body fluids". Or to quote Gorebyss's Pokédex entry from Emerald, "Its light pink body color turns vivid when it finishes feeding." Its name is a portmanteau of the words "gore" and "abyss".
Golbat. From the Pokédex, we learn that Golbat "feasts upon the blood of both people and Pokémon and does not stop until it is full", and Golbat is 1.6m tall and weighs 55 kilograms (5 feet, 3 inches, and 121 pounds). In caves and at night, they can be found everywhere.
Its evolved form, Crobat, is rather creepy itself, being a 5 feet, 11 inches tall, 165-pound blood-sucking bat. Thank Arceus they can't be found in the wild... until Generation V...
Grimer and Muk leak "horribly germ-infested fluid".
A single drop of Muk's fluid can turn a pool stagnant and rancid. Touching causes a fever and its footsteps leave behind poison ground that nothing will grow on for three years. Grimer, while less powerful, is more dangerous indirectly as it leaks more fluid than Muk which may eventually become more grimers. Grimer's germ-infested fluid can kill off all flora (including weeds) and make the land unfit for future plant life, touching it can either cause a horrible flu or fatally poison the victim. Basically, the "facts" imply a rampaging Muk is the Poké-verse equivalent to Chernobyl.
Gulpin and Swalot play on the Primal Fear of getting eaten. Swalot can swallow just about anything (the Pokédex says a car tire is the largest thing it can eat), except its own stomach. And a Swalot has no teeth, so whatever (or, Arceus forbid, whoever) it swallows goes down whole and gets broken down by its stomach acid, said to be powerful enough to melt iron.
Gligar looks like an Ugly Cute cross between a scorpion and a bat, but the Pokedex states it "swoops in silently, latches onto your face, and injects you full of poison". Basically, it's a flying facehugger Pokémon.
Bug Pokémon. While Misty's phobia of bug Pokémon is Played for Laughs in the anime, the fact of the matter is that they are often at least the size of car tires.
Beedrill are said to attack in big swarms, are as aggressive as hornets, have stingers for hands, and are 3-foot tall.
Scyther is a bug the size of a person which is apparently permanently pissed off. It also has scythes instead of hands. Which, according to one of its Pokédex entries, get sharper as it cuts things, meaning it gets deadlier the more it kills.
Its evolution Scizor is pretty much the same, but is coated in metal armor and has metal pincers for hands. Ouch.
Beautifly is a three feet tall swallowtail butterfly whose multiple Pokédex entries say to be savage, and has few qualms about stabbing things with its proboscis and - like Gorebyss from further up - draining all their fluids.
One of the largest Bug-types out there is Yanmega, based on an actual prehistoric giant dragonfly, it is over six feet long, can dislodge trees when taking off, is capable of lifting a grown human off the ground, can shred its enemies' internal organs from the shockwaves created by its wings, and is known for "biting apart foes midflight". Its appearance is scary by itself as well.
Cascoon's Pokédex entries state: "Encased within its tough cocoon, it endures attacks. It never forgets the appearance of its foes.", and in Platinum, "It never forgets any attack it endured while in the cocoon. After evolution, it seeks payback".
Dustox, Cascoon's three-foot-eleven and Psybeam-firing evolved form, is a moth, and as such, it's only active at night, hunting people down while they sleep. And both this and Silcoon/Beautifly come from the same extremely common worm Pokémon, Wurmple.
Scolipede is an eight-foot-tall (not long, tall) centipede (beating out Yanmega's 6 feet) that "clasps its prey with the claws on its neck until it stops moving." Then, as if that wasn't enough, poisons them. And in case that didn't do the trick, it learns Steamroller, which essentially flattens the opponent just like the construction machine of the same name.
Combee are really cute, but being swarmed by a bunch of them would be frightening, which is what Vespiquen forces them to do. The Combee fly out of the honeycomb at the bottom of Vespiquen's skirt-like abdomen, which is exactly why it's shown lifting up its abdomen in its official artwork◊.
Nidorino's horn is "strong enough to pierce diamonds", and he's a Poison-type.
Pinsir apparently likes to grip its prey in his enormous pincers until it is torn in half. Said pincers are strong enough to shatter thick logs.
There are apparently some things Pinsir can't crush. So it just hurls them away instead.
Houndoom is basically a Hellhound, with a little skull pendant and a call that the ancients once imagined to be the call of Death itself. And to make matters worse, if left untreated, their fire attacks will never stop hurting if they hit you. And yet they're still capable of becoming the player character's loyal and trusted friend. They probably have the same problems as Rottweilers do in Real Life.
Latios and Latias are found in the game carrying the item Soul Dew, which increases their stats. In the movie "Pokémon Heroes", it's discovered that the Soul Dew is actually made from the soul of a dead Lati. So the Lati seen in the games is carrying around a trapped soul to make it stronger.
Vileplume is a carnivore. It spreads hyper-allergenic pollen that's also toxic, then chews on those who are immobilized by it.
Spiritomb. It's a Ghost/Dark-type that was sealed away for 500 years as punishment for misdeeds, made from 108 souls. Additionally, Ghost/Dark types have, so far, the only combination that's not weak to any attack.
Not true anymore as of Gen VI, as it's weak to Fairy. Still a nasty Pokémon, though.
Gyarados is infamous in-game for knocking down cities when berserk - that is, always. It also has the Intimidate ability, that has the in-game effect of scaring other Pokémon as well. It can be found in tons of bodies of water.
The flying-type birds are the counterparts of pidgeons, sparrows, starlings, and crows; yet in the Pokémon world, they're all big and pretty aggressive, attacking in flocks. In the anime, a swarm of Spearow were going to actually kill Ash and Pikachu as soon as the first episode. Alfred Hitchcock's "The Birds" inevitably comes to mind. Then there are bigger evolved form of said birds: pelicans that can launch tidal waves, the eagles that know kung fu, and even Giant Flyer ones.
Machoke's arms. "The skin has stretched apart because it can barely contain its huge muscles". Whether those lines are exposed muscles, veins, or stretch marks is never explained, and yet, Machoke somehow manages to smile about it. Manliness alone fails to justify it.
The Timburr line is pretty much 60% veins. Its muscular veins extend across it, which is pretty disturbing when you take a good look at it.
Machamp in general is also creepy. He grows extra arms out of nowhere, and his evolution before has no sign of 2 extra arms coming in from the back of his very spine.
Froslass is based on the yuki-onna, a type of ghost in Japanese folklore that appears during snowstorms and takes the form of a beautiful young woman without feet coming into being when a regular, foot-having young woman freezes to death in the mountains during frigid weather. Depending on the disposition of the ghost, which varies from story to story, it will either guide you to safety or get you hopelessly lost so that you suffer the same fate as she did.
Not to mention what you have to do in game to get a Froslass — they evolve from Snorunt, which is an Ice type. Upon exposure to a Dawn Stone, they become Froslass, an Ice/Ghost. Meaning she melted.
To top this off, because Froslass is based on a Yuki-Onna, this implies Froslass is not above having sex with her victims before said actions.
Not to mention its Pokedex entry...
Pokédex: "It freezes prey by blowing its -58 degree F breath. It is said to then secretly display its prey."
Kabutops' Soul Silver's Pokédex entry managed to make it outright horrifying. To clarify, Kabutops is a vampiric 4-foot tall bipedal horseshoe crab with scythes for arms.
Pokédex: "With sharp claws, this ferocious, ancient Pokémon rips apart prey and sucks their body fluids."
Kirlia and Gardevoir: apparently Kirlia can distort reality and create a rip in dimensions whenever they use their psychic powers. Gardevoir can do that, but are stronger to the point they can create black holes to protect their trainer. They also have more biologically in common with ghosts, walking sludge, and a floating electric viper lampreythan other humanoid Pokémon.
About the map changes, Tyranitar pre-evolutions (Larvitar and Pupitar) are found in the wild in Mt. Silver, near the Victory Road. A zone whose geography has severely changed from Gen I to Gen II, disappearing a whole route. A very transitated route, leading to the Pokémon League.
Larvitar's Pokedex entry describes it as "A Pokémon that eats soil. Once it has eaten a large mountain, it goes to sleep so it can grow."
This is made all the more humorous, considering that X and Y made the two Foils to each other.
Bellsprout's Generation I sprite◊ looks like a skull on a plant.
Victreebel is implied to be a man-eating plant: one of the Pokédexes mentions that "any and all explorers who have found Victreebel's secret society in the jungle never come back".
According to Weepinbell's Pokédex entries, it: a) is full of acid, b) catches prey by dousing it with a poisonous powder, then acid, c) has razor sharp leaves, which it uses to slice up prey, and d) apprently leaves nothing remaining. Oh, and it's a metre tall.
Giratina's overworld sprite in Lost Cave (moreso than in Distortion World) because it's there and you can be walked around. If it equated to actual size, and considering proportions to the player, Giratina is about six times taller than the player and just looks like some sort of Eldritch Abomination centipede/dragon/ghost... thing. It doesn't help how purely roar-like its ID cry is.
Wobbuffet and Wynaut are cute, funny, and surprisingly awesome. But the first is that they're usually banned in tournaments, due to their ability, Shadow Tag, which prevents the opposing Pokémon from switching out. Also, its tail: it's mentioned in the Pokédex that there's a secret about them, and that Wobuffet are oddly protective of their tails. Someone figured this out when looking at how Wobuffet looks and acts like an inflatable punching bag, because it actually is (and in the Super Smash Bros. games it acts exactly as such). The 'eyespots' on Wobuffet's tails may well be its real eyes, and the tail might well, in fact, be the actual Pokémon: the entire body is merely a protective decoy.
Dusclops is a cyclops shell with a giant glowing red eye; a shell as in, "it is a black hole on the inside", that can brainwash people just by waving its hands around. Duskull have always been creepy to some, despite the "But it's so cute!" found in much of the fandom; nevermind the Pokémon's very Grim Reaper-esque features.
Xatu is a clairvoyant Psychic/Flying Pokémon that the R/S Pokédex describes as silent and unmoving because "shocked by the terrible things it sees in the future". In other words, Xatu is a Pokémon that spends most of its life paralyzed in fear: a flying-type, paranoid bird with psychic powers.
Poliwag's cute spiral is, in fact, its internal organs, which can be seen though its skin. However, when evolving, the swirl changes direction.
Tentacool and Tentacruel are based on jellyfish. Jellyfish have tentacles lined with millions of tiny stinging structures designed to inject venom that, depending on the species, can cause incredible pain or death in humans (also mentioned in its Pokédex description). What makes this wores is Tentacool's status as Goddamned Bats in the water areas seen in the games.
As mentioned before, taking an Arceus (provided players own one) to the Ruins of Alph results in the most out-of-place, trippy cutscene ever; afterwards, Cynthia points out that "this is what happens every time an egg is created". As in, what always happens at the Day Care. According to Word Of God, the images you see are actually Arceus recreating the universe from scratch just to give that egg.
Gen V Pokémon Musharna, with pink smoke protruding from its head, who seems to be perpetually sleeping: this has the unfortunate effect of making it look as though it's suffered a grievous head injury.
Another GV Pokémon, Cofagrigus, is a sarcophagus with a malicious grin on its face and ghostly hands peeking out of the inside of the coffin. Its ability, Mummy, gives the same ability to anyone hitting him: in other words, Zombie Apocalypse.
According to its Pokédex entry, it pretends to be a fancy coffin so it can punish grave robbers. And also, its pre-evolution was apparently born from the spirit of someone buried in an ancient grave, and it still remembers its past.
Yamask's Black Pokédex entry says that the mask on its sprite is actually its former human face, and the Pokémon weeps over it. This brings many feelings.
Sableye. According to the Ruby Pokédex, they're thought to steal the spirits of people when their eyes glow in the dark. Their eyes are made of crystals. However, Sableye's eyes turned into gemstones because they EAT gemstones. Sadly, doing the math is not for the best here.
Magneton: the Pokédex says that 3 Magnemite join together to form one of these. However, Gameplay and Story Segregation makes it worse, as even with three Magnemites in the party, when one evolves, the others are still there, leaving the player wondering where did the others come from. (budding?)
Even worse: what happens to the other two when they evolve into Magnezone. They appear to be partially absorbed by the middle one.
The Dark/Dragon line of Deino, Zweilous, and Hydreigon is a dragon that starts with one head, grows a second one when he becomes Zweilous, and gains a third one as Hydreigon; while two of them become hands. The creepiness comes from the dex entries: It says that Zweilous's heads fight over food, which means that both of them are intelligent. According to Hydreigon's dex entry, "The heads on its arms lack brains." One of the heads loses its ''brain.''
Alternatively, its brains merge and it's driven insane, accounting for its "brutal" nature.
Hydreigon is also one of the few Pokémon who appears to be explicitly malevolent and destructive in nature. It's even called the Brutal Pokémon.
And to make things worse, it's another creepy Pokémon that Ghetsis has in his possession. It's the cornerstone of his team.
Litwick is a cute little Fire/Ghost candle, but the Pokedex says "It burns brighter when it absorbs a human soul", and that "It tricks people into thinking it's a helpful guiding light before doing so". Its evolved form "wanders the streets actively looking for the souls of the dead", as well as "appearing when you're on your deathbed and severing your immortal soul from your body".
Made even creepier in Black 2 and White 2, where a young girl challenges you in the Celestial Tower with one. After losing, she says that losing battles makes her tired. In other words, it's leeching off her life force, and she has no idea what's going on. Made better by the fact that she goes to the Pokémon Center afterwards to rest, but it's still creepy.
That's right, kids - even your own Litwick will leech off your soul, so being its owner doesn't even make you safe!
The White 2 entry outright states that, "Its flame is usually out, but it starts shining when it absorbs life force from people or Pokemon". Its sprite always has the flame lit. So either it's feeding on the Pokemon it faces, or Nate/Rosa are going to end up lethargic...
Genesect, a Generation V legendary, was feared as the ultimate hunter, and as such, probably locked up somewhere for a really good reason, like Team Plasma boosting its strength to legendary levels.
It was feared as the ultimate hunter 300 million years ago, long before humans, when there were mostly small lizards, amphibians, and bugs. That overpowered monstrosity could have easily wiped out all life on the planet. And there wasn't just one of them, it was an entire species. So imagine hundreds of five-foot tall bipedal insects with cannonsnote Its Pokédex entry only says that Team Plasma powered up its gun running around killing whatever they want to, because their closest competition is some ancient lizards, frogs, and giant dragonflies (Yanmega). It's a good thing it went extinct.
It gets worse when you consider why it might have gone extinct. Species generally go extinct when the climate changes too much for them to adapt, their food source goes extinct, or something else outcompetes them. That provides two new horrors: Either Genesect wiped out the local ecosystem, or something even worse took over.
As if that wasn't enough, take a close look at Kabutops, an extinct Pokémon that's already creepy enough on it's own. Now look at Genesect again. Notice anything suspicious?◊
Seismitoad, another Gen V Pokémon, essentially looks like a Politoed, only blue and with a bunch of orbs around its skin: one of its available abilities, Poison touch, causes anything it touches to be poisoned. Oh, and it's said to spray acid from the orbs on its head. And Ghetsis has one.
Primeape is a prime offender. Pretty much every Pokédex entry mentions its Joe Pesci-like tendencies. As in, it can be pissed off by pretty much anything.
Frillish paralyze prey with poison, then drag them down to their lairs, five miles below the surface.
Jellicent. The line from its Black Pokédex is disturbing: "The fate of the ships and crew that wander into Jellicent's habitat: all sunken, all lost, all vanished." The white Pokédex mentions that "life energy" is its favorite food.
That's nothing. In Black 2 and White 2, the Pokedex states that it has an undersea castle made from the ships that it attacked.
This might be a bit problematic for the Unova region, given that Jellicent can be found readily in most bodies of seawater. No wonder they're so big on trains.
Elgyem, the alien Pokémon introduced in Generation V. It and its evolved form, Beheeyem, can completely rewrite a person's memories, and the fact that they're aliens and have seemingly attracted little attention from the scientific community means that they probably do this whenever someone sees them.
Durant: Ants that are thirty centimetres tall (roughly 11 inches), with steel covered skin that would make it nigh impossible to stomp on them.
Heatmor's dex entry. It grabs a Durant, blows fire on it until the heat melts its exoskeleton into slag, then delightfully cooks its internal organs and devours them one by one. Of course, given Durant is a bug- and steel-type, it's only logical that his Arch-Enemy is a fire-type anteater, akin to the Zangoose/Seviper rivalry and Zangoose's Immunity.
Eelektross is an enormous lamprey that is also a living dynamo. It hunts by slipping out of the ocean, grabbing its prey, shocking them, and chowing down. And Ghetsis has one.
It also has no weaknesses in the games. Its type's only weakness, Ground, is canceled out by its ability, Levitate.
While Volcarona is mentioned as having been deified as a bringer of light, it still is an enormous moth that spreads embers wherever it goes; one flap of its wings is enough to set vast swaths of land ablaze. And it's just one of many.
As far as openly malevolent Pokémon go, there are Tornadus and Thundurus, the storm djinns. These are pogeys who, for no apparent reason whatsoever, flew around causing massive, land-devastating storms at random. Thankfully, they have a mediator in Landorus.
That And I Must Scream bit is even worse that it sounds. It turns out that the fusion isn't even a complete one, since N outright says he can hear his dragon trying to speak to him. Plus, this makes one wonder if absorbing both Zekrom and Reshiram would actually allow it to be complete again (thankfully we never find this out).
Gothorita, the Pokémon that is known far and wide in Unova for hypnotizing people. Sometimes those people are never seen again. Its Dream World Ability is Shadow Tag and its pre-evolved form is known for obsessively staring at people.
Ditto. Found where Mew was cloned, with its same colors (both are pink normally, and blue when shiny), and the same weight. Adding the fact that both are the only Pokémon that can learn transform, Ditto might well be a failed clone of Mew (which explains why it's a melted blob).
Starmie's Pokedex entries suggest that it might be an alien species and that its core sends radio signals into space.
The Regi Pokémon: Regirock, Registeel, or Regice. They're giant, faceless stone golems that have been around for apparently an extremely long time, as indicated by Regice's pokedex entry of it being formed during the Ice Age. Not to mention their "boss" Regigigas, who has been rumored to move entire continents.
Zangoose, while badass, can be scary considering a closer look at its fur suggests the red markings are blood and scars. His paws appear to be blood soaked, too. And it's pissed off all the time.
Cherubi is a sentient cherry with eyes and a mouth. The fact that it has a second, smaller head it can eat for nourishment is even creepier.
Lampent hangs around hospitals waiting for people to pass on. It does WHAT?
Scolipede - It clasps its prey with the claws on its neck until it stops moving. Then it finishes it off with deadly poison.
Imagine this, a bird. Not that scary, right? Ok, now picture a bird that stands at 17 feet tall. Unnerving, but not that scary. Now, imagine this bird looks like some sort of draconian beast. Not only that, but said bird was once worshipped as a god and (accidentally) caused a terrible storm that burned down the tower it perched on killing three Pokemon inside due to it losing control of its immense power. Also, imagine that a single flap of its wings is enough to cause devastating hurricanes. Folks, say "hello" to Lugia.◊
And, to make Lugia even scarier? Meet Shadow Lugia◊. It's basically a Lugia forcibly turned "evil" by turning into a fighting machine. Did we mention that it's established that "Shadow Pokémon" in general are known to attack humans? Yeah, let that sink in.
On the bright side, Lugia isn't always Nightmare Fuel, as shown by a three episode story involving a baby Lugia and its parent and the second movie, when another one serves as a guardian to Shamouti island.
Behold Arceus◊. Doesn't look too scary, right? Just a weird-looking Kirin horse-thingy Pokemon, right? Nope. For one thing, its signature move "Judgement" is capable of destroying entire cities and taking out weaker Pokemon with ease. Not only that, but its "Multitype" ability allows it to become any of the 17 elemental types of Pokemon available (meaning it can also learn a wide variety of moves). Oh, but it gets better. You see, Arceus isn't just any run of the mill Legendary. It just happens to be the Pokeverse's version of God. Luckily for us, "God Pony" prefers to nap and not interfere with the Pokeverse directly. That is, unless you piss it off, then it will go so far as to destroy the entire world in its rage.
Pawniard and Bisharp. Carnivorous Pokémon that'll hunt their prey down, at which point the Pawniards will imobilize it by clinging to it sinking the blades their bodies are made of into the prey's body, followed by Bisharp making the final blow. And guess what? Ghetsis has one!
Spoink's Pokédex entries state that if it stops bouncing, its heart will stop and it will die. Its fainting animation in Colosseum and XD: Gale of Darkness have it falling onto the ground.
The worst thing about this harbinger of destruction is that, counter-intuitively, its existence and life are necessary for life on Kalos to continue. It's like a Keter-class SCP that you have to preserve at all cost lest it causes even more casualties.
Then there is Honedge, a possessed sword. Looks like an Equippable Ally, right? Wrong! In fact, it is an Artifact of Death that punishes those who try to invoke it and wield Honedge like a sword will find its tassel wrapped around them and sucking their life force dry. Nowhowwould Kalos' residents know this fact? It's a good thing that Aegislash, its final evo, is more benevolent. Except not in X, in which it's a mind-control tool for despots.
Many Pokemon have spots they don't like to be touched in Pokémon-amie. Honedge is fine with its hilt being rubbed, but if you touch its scarf-arm it bristles furiously and makes as if to unsheath itself. But you're its Trainer, so it settles back down. Doublade is much more easygoing.
For Adult Fear you couldn't go wrong with Phantump. Specifically, the part where they come from the souls of children who died in the forest (suddenly Yamask's backstory of how it's the soul of a person who carries the mask of its human face and cries over memories of being alive isn't that heartbreaking). Its evolution Trevenant is no less creepy — think of the evil tree from Poltergeist, only with spider legs and a big single eye. And you can encounter hordes of them. A tree stump haunted by a dead child, becoming someone's servant or pet. What Do You Mean, It's for Kids?
Gourgeist, the evolution of Pumpkaboo. Its Y dex entry states it sings joyfully while watching its prey suffer.
Whiscash looks goofy, but it's an extremely territorial Pokémon that will generate a three-mile-radius earthquake when in danger. It will also eat anything that's alive.
Amoonguss uses its Poké Ball mimicry to lure prey, but Pokémon aren't usually fooled by it. Now, what species goes around picking up any Poké Ball they see lying around?
Tyrunt and Tyrantrum are Pokemon based off of T-Rex. And they both have violent tempers. Tyrunt may be cute but it throws tantrums when it does not get its way. And Tyrantrum´s bite is so powerful that it lived as a king in its time because nobody could fight him!
Igglybuff's unsettling, enormous red eyes add an unnerving edge to an otherwise adorable Pokémon.
Canon adult horrors (that aren't the Pokédex entries)
This stuff really happens. Ain't no fanon here.
There is a house adjacent to Milstraton City in Pokemon Black/White. If you talk to the family inside, it sort of sounds like the father or the grandfather is abusing the little girl's mother.
At Celestic Town, another Galactic Grunt mentions a "package"- and he's open with it and going to destroy Celestic Town with it. They aren't just a crime syndicate, they are terrorists.
The package turns out to be an actual terrorist bomb designed to drain one of Sinnoh's sacred lakes.
Pokémon: Lucario and the Mystery of Mew, the movie featuring Lucario, confirms a terrifying fact: in ancient times, Pokémon used to go to war with their human trainers/soldiers, who used them instead of weapons. Considering what Pokémon have often been confirmed to be able to do, it could actually have been worse than nuclear warfare.
Considering what little of Lt. Surge's background is given and dialogue of a trainer in his gym "Gentleman Tucker", wars with Pokémon still happen in the present time..
X and Y outright confirm it. There have been wars in the past, that Humans and their Pokemon take part in. Most likely the only reason AZ didn't fight yet his Pokemon was enlisted was because he was King and literally could not even if he wanted to
Escalation of the villainy of the various teams: Team Rocket were generically nefarious, but mostly dim and restricted to ordinary organized crime; Team Aqua wanted to expand the oceans, which would have drowned coastal cities, and Team Magma wanted to expand the landmass, mostly by causing a volcanic eruption. Team Galactic wanted to summon a godlike being in order to destroy the universe and recreate it: they wanted to end existence and create their own, supposedly "better" universe with Cyrus as the supreme ruler. In Platinum, the "perfect world" Cyrus wants to create is a "world without spirit". He wants to unmake the world, and purge it of all traces of individuality, emotion, knowledge, and thought. And even after defeating him and pacifying Giratina, he says that he has not abandoned his plans, and leaves with this ominous line: "One day, you will awake in my world. A world without spirit."
Cyrus' fate in the anime is perhaps more disturbing than anything he did in the games. Basically, he walked into outer space, and the portal he used to do so was then destroyed by Dialga and Palkia. It's possible the whole thing went with it and he's dead now.
The Distortion World, known as the Reverse World in the 11th film. The idea of a world where gravity shifts under your feet may or may not be frightening to some people, but it starts to get disturbing when platforms hovering above an endless void disappear right as players try to step on them... and when very tall sunflowers grow backwards into the ground when approaching them... and when people behave oddly and then suddenly disappear into thin air. That, the dark color scheme, the Eldritch Abomination that flies overhead every so often, and the creepy music add up to an overpowering feeling that this is a place man was not meant to see.
In Platinum, the new opening video and title screen got pretty... creepy. It ends with Giratina's wide red eyes and glowing red grin shining up from a swirling abyss. And while it happened back in Pokemon Red And Blue, this is the game that started the tradition of the Version Mascot'sscream as soon as players "Press Start".
The fate of the Cinnabar Islands and Blaine in the original Gold/Silver: Cinnabar blew up, almost everyone who lived there has left, and Blaine's become a recluse - yet still a gym leader — in the Seafoam Islands. Thankfully, following the eruption, as remarked by one guy found in the Cinnabar Pokémon Center (as of the remakes at least), everybody got away from the island safely.
The Lake Trio, Azelf, Mesprit, and Uxie, can turn people into stone, take their emotions, or wipe their memories, respectively, as each one acts as the deity in charge of each aspect. And none of this can be reversed for one thousand years.
How the researchers fill out these Pokédexes in the first place is a big source of Fridge Horror, as, for example, Houndoom's flames inflict never-ending pain, Muk's poisonous "skin" can turn a virgin lake into a stagnant swamp and whose toxicity can lead to death, Froslass ices her victims as trophies, Spoink's heart is dependent on it bouncing up and down constantly (and if it ever stops, it will die), Dusknoir sends souls to the spirit world, and the list goes on.
The manga is truly terrifying when it's not being awesome. Reanimated zombie Pokémon with half-rotted bodies (current page image, see above), an Arbok being sliced in half (with gratuitous blood), a kindly old man who becomes a psychotic ice demon upon donning a skull-like mask, said man kidnapping six young children to train as his personal faceless minions, crystal mirrors that trap people in a temporal river, a space-virus-turned-lifeform that contains the blood of the main character, Archie killing Maxie for an immortality-granting suit of armor, and then the same guy later dying when he loses that armor are just some examples.
What's worse is how Archie dies when he does lose the armor: he just fades out of existence, not leaving anything behind.
What happened to Giovanni in HGSS: beaten by a kid again, and apparently Driven to Suicide as a result, if the dialogue and the height of the waterfall are taken into consideration.
Gold and Silver has the Lake of Rage before thwarting Team Rocket, as Gyarados - normally - are described as being unable to control their power, and so they go absolutely crazy with it, vaporizing everything around them until there's nothing left to violatenote (Sapphire Dex Entry: rampages have been known to last for up to a month). They have also exhibited tendencies that suggest they are drawn to violence and rage. Apparently, this change in temperament is thought to originate in a Magikarp's brain cells rewriting themselves upon evolution. After these premises, in Team Rocket's hideout, a creepy little Easter Egg melody can be listened to, thanks to the PokéGear radio: it's a transmission that Team Rocket is using to evolve the Magikarp into Gyarados involving plenty of scary sounds. Team Rocket is impied to have planned to take it even further by having it driving every Pokémon in Johto crazy as well, near populated areas.
It's also explicitly mentioned that the Unown communicate using radio signals: Ruins of Alph is the only place to hear them, as that's where they live, only this time the scary noise can be listened to at will. It's not as hellish as much as it relies much more on scary vagueness.
Pokémon: Diamond and Pearl Adventure: When the heroes follow Charon and his goons into the Distortion World, they find not only a creepy landscape, but a creepy landscape littered with bodies. All the Galactic grunts are lying around with no signs of life. A moment before, they were screaming for help.
The end-game of Ruby and Sapphire: while Team Galactic didn't get to trigger the apocalypse they wanted, Team Aqua/Magma did. Of course, the hero saves the day, but a brief Darkest Hour actually happened for real this time.
The Trick House in R/S/E is an optional area that allows players to get rare, exclusive secret base items. It is run by a man who calls himself the Trick Master, who "welcomes" the player by saying "You're being watched" without actually being there. Pedophiliac implications are evident.
In N's Castle in B/W, trainers are given the chance to heal their Pokémon and access the Pokémon storage system. In the room allowing that, a scientist says that they "have successfully hacked the storage system, and can now release all the Pokémon stored within as soon as N gives the command". Suddenly, old foes like Team Rocket seem insignificant.
N's entire backstory has him isolated from any human contact (possibly from birth), housed only with Pokémon that had been abused and abandoned, groomed by Ghetsis to be pure and innocent in order to win over the Pokémon of legend and defeat the Champion so he could order the entire country to release their Pokémon, and when N had served his purpose, Ghetsis would have murdered him and taken over Unova. Going through N's room in the castle really brings it home, as many of the toys were quite recently played with. N was a pure, innocent Man Child being massively used.
Ghetsis himself: although the chanting of his name sounding like Dennis in his battle theme and his taste in clothing diminished this a bit at first, actual players found out that he was not to be laughed at. He is quite possibly the single most horrific character in the Pokémon franchise, and only the heads of Cipher, the Mystery Dungeon incarnation of Darkrai, Purple Eyes, and Grings Kodai can possibly rival him for that position. The sheer amount of fridge horror from the supplementary information in the post-game (what with being implied to not be N's real father and managing to somehow get the Adamant, Lustrous, and Griseous orbs) arguably puts him on a whole new low, even among the other villains of the Pokémon Universe.
One of the Seven Sages says that Ghetsis might not be N's real father. Then whatever happened to his real parents is never addressed.
Ghetsis' Pokémon party, coupled with the in-game Pokédex descriptions mentioned elsewhere in this page, implies heavily that their sole purpose is to be their trainer's instruments of murder: his plan to be the only trainer in the whole world pretty much confirms it.
In Black 2/White 2 when you confront Ghetsis in the Giant Chasm, he talks about how sick he is of you foiling his plan and he sets his mind controlled Kyurem to attack you by using glaciate, luckily N and his Zekrom/Reshiram swoop in and rescue you in the nick of time, but just imagine what would have happened if N hadn't saved you.
In one chapter of The Electric Tale of Pikachu Ash's Charizard is fighting Ritchie's. While in the anime he fights Ritchie's Charmander and falls asleep on Ash, in this manga he becomes violent to the point where he's using lethal force on Ritchie's Charizard. Ritchie is unable to call back his Pokémon and Charizard won't snap out of his rage so Ash has to put him into his Pokeball. The scene is quite bloody.
From the same manga, the designs for the Pokémon. When they aren't sickly cute they're often realistic and/or gritty. There's also a giant Haunter known as the "Black Fog" who murders people.
The ending of chapter 11 of Pokémon Special's Black and White arc is rather creepy. White jumps out of a Ferris Wheel while it's still on - though apparently it's not that far up. As her Tepig just betrayed her she's in tears - but she's lying down in an awkward position with Mind-Control Eyes.
In one How I Became a Pokémon Card oneshot the protagonist, Akane, is an orphan who was raised by Impostor Professor Oak. As his name says, he's an impostor of Oak. Nothing is verified about him in this man and in the source cards he's a Team Rocket member.
X and Y have the ultimate weapon, a machine of destruction and/or immortality, depending on the version. It's powered by the life energy of Pokemon. The game outright states that many lives were lost to charge it.
Team Flare Grunt:Nope! I can't hear them! I won't listen to the Pokémon's cries!
In Pokemon X Lysandre turns the ultimate weapon on the exact location you're battling, intending to render everyone present immortal. The entire area caves in leaving him and much of Team Flare trapped. Potentially forever. Assuming a direct hit isn't necessary for the effect to occur, a shockwave did pass over all of Geosenge Town, it's possible that everyone there is now like AZ including the player andtheir friends.
On the lighter side, at least you have your friends and Pokémon to keep you company for an eternity. Perhaps you all could just start up a permanent residence in Geosenge.
Also on a lighter note, AZ is over 3000 years old but doesn't look a day over 60. In fact he looks even younger, instead of shrinking and becoming a frail decrepit skeleton man, he is ten feet tall and very muscular/fit Apparently Age Without Youth is very kind in the Pokemon world. Or ImmortalityBeginsAt60
In Pokemon Y, Lysandre intends to destroy everything and rule over the remains. When that plan fails, he shoots the weapon straight up, destroying the base.
There's a small segment in Pokémon Platinum that is often forgotten but ranks easily as one of the most unnerving moments of the series. Right after the second battle agains Cyrus inside Galactic Hideout, you descend to the basement where the Lake Trio is held captive. Not only the theme played there is really unsettling, but you get to: 1)Talk with the scientists that worked on Cyrus' plan, and they are horrifiedwith the results of the research; 2) Find the Lake Trio trapped in machines being apparently tortured and 3) Go through a wing full of huge pods filled with green fluid with....something floating inside. We never find out what the "something" is. Considering the situation, just imagine what it could be. Science done wrong at its most real form.
Most evidence points to the fact that a Pokémon inside a Pokéball is simply shrunken down and confined to a very small space, while completely conscious. Stuffing a creature into a tiny confined space, only to let it out to battle other creatures? Certainly sounds like blatant animal abuse...
A meta example which applies to the first two generations: these games are based on battery-backed saves, rather than the flash memory that became standard starting with Ruby/Sapphire. These batteries have a finite amount of power, and when they run out, the data on the carts is reset. (In fact, many of those carts are due to begin running out of power soon.) And, more crucially, there is no way to transfer your old Pokemon off of, at best, Crystal to new generations with non-volatile memory. This means that, short of incredibly complicated dumping of a cart's SRAM, your old Pokemon friends are DOOMED TO DIE. You can't even change the battery to save them - if the current is interrupted even for a second, poof. They're gone. Forever. There's nothing you can do about it. Your old Pokemon are literally facing mortality, or at best an ethereal half-existence on your hard drive (since there's no easy way of dumping them back into a game after you change the battery).
And yes, even the N64 games are battery-backed. No help there.
It's really not so much being doomed to die as it is an irreversible Time Crash, especially if starting a new game can be considered "resetting" time to a certain point. That said, a Time Crash isn't a particularly pleasant concept either. Just think, your Pokemon essentially cease to have ever existed to everyone except you.
Granted, RSE and up also face the threat of bit rot and even slow degradation of the physical memory itself, though this should take much longer to happen, especially if you keep your carts in good conditions for long-term storage (not too much moisture, etc). And since every generation since III has made sure to feature full transfer upward between gens, it's much easier to keep your 'mons on new silicon.
The eShop version of X & Y features saving to the SD card, which will make it trivial to keep your mons on fresh silicon in foreseeable perpetuity, granting them proper immortality.
Pikachu"s fainting cry in Pokémon Yellow.
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 description for the Payapa Berry says "This Berry is said to sense human emotions for the way it swells roundly when a person approaches". Basically, sentient fruit: a vegetarian's worst nightmare.
Goes from Nightmare Fuel to Fridge Brilliance by understanding of botany and the purpose of fruit; The swelling is most likely to make the fruit appear more appealing and encourage consumption, since it's in a tree's best interest for animals to eat their fruit. It is most likely the tree sensing human emotion (Also fitting, since the berry is the one associated with the Psychic-type), not the fruit.
The look in Entei's eyes when he puts a spell on Ash's mom in Spell Of The Unown.
Entei: "You... are... MAMA!"
The eighth movie gives us a scene in which 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.
Exeggcute, the psychic swarm of sentient seeds.Sunkern (sentient sunflower seed), Seedot (sentient acorn), Ludicolo (sentient pineapple fruit), and Cherubi (sentient cherries) all are sentient edibles.
Then, in "Battling The Enemy Within" in the Battle Frontier saga. Ash gets possessed by an ancient evil king. Complete with mascara effects to better show the Demonic Possession.
In another example, in "Team Plasma's Pokemon Power Plot," Pikachu has brainwashed red eyes again, but these are much creepier. It's almost like they're not even there. Just two soulless red cavities in the face. See for yourself.◊
Pokémon Snap allows the player to take a photo of anything in-game, including jewels: when their photos are developed, players get Spooky Photographs as a reward. Also, Charmander can get pretty screwed up.
The Heartbeat Soundtrack when you encounter Mew; it gets faster the closer you get to breaking it out of its bubble.
The holes on the outside of the abandoned ship in R/S/E look human-shaped.
In the Gen II games, the aptly-named 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 Game Boy 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, 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 lacks any BGM, and is the only place in the city labeled as "Foreign Building". The people inside it and their Navel-Gazing come off as really creepy.
The Nurse Joys in the Pokémon Centers, whose "Hope to see you again soon" message, coupled with 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.
In Pokémon HeartGold and SoulSilver, the first Pokémon in the party gets to walk with his trainer (like in Pokémon Yellow). It can be talked to and it would be doing something cute depending on the area. One of the text will say "_____ poked your belly!" That sounds really cute if it's, say, a Pikachu... but if it's something like a Scyther, Fridge Horror ensues.
Players wandering through Victory Road who talk to their trailing Pokémon may get the message "___ cautiously eyes the trap".
Coupled with each Pokémon appearance, features, and Pokédex description, the Walking Pokémon feature is a Fridge Horror magner: "TYPHLOSION is having a fun time rolling around in the grass"; "WAILORD jumped for joy"; "MUK suddenly hugged you!"; "GYARADOS is making a face like it's angry"; "CHARMANDER is splashing around in the water"; "SHEDINJA turned its back to you defiantly"; and so on.
In the Anime, the episode Electric Soldier Porygon was banned from ever airing again, due to a bright flashing background at one point in the episode that reportedly gave over 600 children siezures, talk about super-effective. To this day, Porygon has only ever shown up once more as a short appearance in one of the movies, and niether Porygon-2 or Porygon-Z have ever appeared in the anime or movies even once. This is most likely due to fear of outraged parents.
Lorelei threatens some Rocket grunts with her Lapras' Ice Beam in FR/LG.
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 Random Encounter, but the music is different. And then an enormous beast appears instead of a local Pokémon and disappears as quickly as it arrives.
The "bus driver" ad that played in Western countries is downright horrifying. Well, okay, just how malevolent that guy is can be 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 implications of the random trainers that dot the landscape in these games: while they're generally implied to train Pokémon as well and battle each other, others outright say they've been waiting for the player.
Also, some trainers run around in circles, so they don't stand there ambushing people forever. Also, in Black and White, the NPCs actually walk around and sometimes come up to you to talk.
Some of those trainers are just children. Some trainers aren't. Like the swimmers, treading water in the middle of the deep sea, sometimes at night.
This includes one kid in Hoenn Route 102, who is seemingly doomed to stand in the middle of a grassy patch forever even though it sets off his hay fever.
Poison-types are weak to Psychics. The probable reason is, the psychic waves overload their senses and excretion of poison, making their bodies damage themselves.
Ever wonder why Fire is super effective on Steel-types? Because metal warms up pretty fast, and sometimes it can even melt.
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... a rock. In addition, 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. Finally, 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.
In the original Red and Blue, several Trainers carry whips. Among them are Rocket Grunts. They're abusing their Pokémon.
Not necessarily true; AJ of the anime series had a whip, but he used it to signal his Pokémon rather than to actually hit any of them with. Understandable mistake, though; Ash made the same assumption.
Realistically drawn Pokémon can actually be quite freaky in an Uncanny Valley kind of way.
Internal Clock Battery failure in Generation II games and not knowing about it before hand: it resulted in the save file Lost Forever, and the game forever losing its ability to save.
To a similar effect, clock failure in Gen 3. It's always the same time, the same day forever. It just goes on and on. Just like Groundhog Day, only worse.
Fortunately, there are ways to fix this, including replacing the battery, although some of these will erase your current data.
Trying to print something from Gold/Silver/Crystal with no Game Boy Printer attached results in an error screen and start playing a strange, haunting and slightly depressing little melody.
Actually, you might have some Fridge Horror or Fridge Brilliance going on there. All of the 'Creation Trio' (Dialga, Palkia and Giratina)'s cries sound like screams. Being the gods of such strong things (Time, Space, and Antimatter), some people probably died when Dialga, Palkia, and Giratina were just learning to use their powers. So what if their cries are the screams of the people they killed? It was the first thing they ever heard, so they associated it with themselves! Bonus points: Dialga's cry sounds like a mess of pitches, possibly symbolising someone going from adult, to infant, and then back before dying.
Some of the Pokémon card images from the early sets were rather disturbing. Particularly Gastly from the Base Set.
Some of the sketchier art, such as the Diglett in the Rocket set.
The idea of the Pokémon world actually existing, considering the aforementioned Pokedex entries.
The Zorua/Zoroark movie, 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 even worse when left to the imagination.
Sturdy lets a Pokémon survive OHKO attacks like being frozen at absolute zero or having its internal organs drilled into mush... or even just a stupidly powerful attack. By that time in real life, the Pokémon would have gone beyond pain, barely coherent and screaming at you to make it stop.
Pokemon with Sturdy take no damage from OHKO attacks, though
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.
Kakuna may look goofy, but cocoons look just like that.
The extent to which Pokémon are Serious Business in-story can get very disturbing. In Hearthome City, there's an NPC with a baby that says "Papa! Mama!", but the parent may actually be thinking about "I can feel the baby stroller getting heavier each and every day. I wonder what kind of Pokémon my child will become friends with first?".
Trainers forcing players to battle, whether they want or not. Case in point.
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 this battle music.
Just when the anime starts calming down on scary stuff, Ash and his friends (as well as Team Rocket eventually) find themselves in the Litwick Mansion. While the Pokedex entries state that Litwick, the little candle Pokémon, leeches off a human's life force, the Litwick in the episode actually try doing that to Team Rocket. Not only, Team Rocket's energy is drained slowly, over the course of the episode. Thus we see them become more and more lethargic as time goes on only to end up looking like zombies eventually.
It gets even worse at the climax, when the Litwick open a portal to a ghost dimension and try to suck everyone in. Eventually, Jessie loses her grip and goes flying into the portal. Ash saves her, but the look of absolute horror on her face when she's getting pulled in is just bone-chilling. And her line just before slipping.... ugh.
Jessie:(whimpers) "I-It's over..."
When Pokémon Hunter J tried to capture the Lake Trio, the remains of J's vessel are almost assuredly stuck at the bottom of the lake, and while the crew would have died quickly, her Pokémon's Pokéballs may have survived intact. Surrounded by rubble. At the bottom of the lake. For a long time.
Apparently, the original planned name for the starting town in Gold and Silver was supposed to be "Silent Hills". Given the similarity to, well, Silent Hill, that would have been a kinda rough way to begin an adventure.
Actually, Rogenrolla and Boldore's dents are ears. Gigalith's dents are also ears, but you can see eyes there too... so it has eyes inside its ears. Squick.
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 captured was still able to reveal its location to Ash using their aura connection. This means that when J turns Pokémon into stone,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 Sideshow Bob.
Almia Castle in the second Pokémon Rangers 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.
Black 2 and White 2 take the very idea of Stockholm Syndrome and abusive Trainers and chillingly twist it just a little bit. In Poké Star 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 "Red Fog of Terror" movie in Pokéstar Studios is riddled with Nightmare Fuel abound, as it's supposed to be a horror film.
In Black 2 and White 2, there's a Backpacker in the Lostlorn Forest who, if you answer yes to his question, gives you TM95, Snarl. He then starts on his way off and transforms into a Zoroark. That's pretty weird.
He probably was Zoroark using its illusory abilities.
The player character is actually visibly startled by this, making it even weirder.
That star-shaped marking on Accelgor's forehead is actually a gaping hole for where its shell used to be attached.
Jirachi, the wish-granting cute fairy, starred in one of the movies, with its voice actor being Tomiko Suzuki, whose role as Jirachi was her last: Suzuki died of a fatal heart attack only a week and a half before the film's theatrical release. Coincidentally, Suzuki passed away on the day of Tanabata, the Japanese star festival with which Jirachi is commonly associated. Additionally, Jirachi's signature attack is Doom Desire, which is highly volatile but has a delay before it strikes.
From Pokepark Wii: Wonders Beyond - The tradeable Spy-Scope item allows one to "see far and see too much," according to the description. It's the only tradeable item in the game with such eerie wording...
The animated trailer for Pokémon Black 2 and White 2 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. It takes nothing short of a Big Damn Heroes 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.
Sabrina. Just everything about her can be a bit disturbing for younger viewers of the Pokemon anime. A girl with Psychic Powers, Sabrina and her Pokemon all have Glowing Eyes of Doom for whatever reason, and she even has a doll of herself and her younger mother, and even possesses a doll to play with Ash and his friends, which almost feels like something from a Childs Play movie. And when she finally gets her emotions, her little doll mysteriously fades away.
While we're talking about Pokemon gym leaders, there's Lt. Surge. Before Ash and co. even meet him, they're greeted by a carnage of brutally defeated Pokemon that tried to fight his Raichu, so much so that the city's Pokemon center was overflowing by the time they visited it. Compared to many other leaders, Surge was positively ruthless.
Not to mention what his Raichu is capable at full power. Its Thunderbolt was capable of tearing the gym to shreds.
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 Back from the Dead.
In Generation I, running out of usable Pokémon causes you to pass out. One possible implication is that after you lose all of your Pokémon, the wild Pokémon or trainer that you were fighting then attacks you, the trainer, knocking you out.
Jossed, starting with Generation III, however, as the Trainer either pays their opponent prize money for a Trainer, or loses it in a panic for Wild Pokémon, then proceeds to scurry back to a Pokémon Center, while "protecting the injured Pokémon from further harm" - although the image of a person as young as 10 forced to singlehandedly fight off rabid beasts, and even criminal gangsters and terrorists with their bare hands is pretty damn scary in itself.
Razor Claw's description is "A wickedly sharp claw perfect for raking enemies. It allows a certain kind of Pokémon to evolve."; one of the definition of rake is "to claw at; to scratch". Now imagine doing that with sharp claws...
And then, there's Espurr. With its eyes. And the implication of being a psychic bomb ready to explode, at any time....
Malamar from XY's 19th episode. Its capable of hypnotizing people and Pokémon into doing its bidding. The thought of being mind controlled is horrifying enough, but being mind controlled into committing horrible actions like attacking innocent people and turning Pokémon against their trainers in the name of world domination is just terrifying. This Malamar was even working on a secret weapon to help in dominating the world. But this weapon is just as horrifying as Malamar itself!
The weapon itself doesn't even resemble anything man-made either, as it looks more like Meat Moss or something organic. No explanation is given to its function as it's quickly destroyed as soon as it's been discovered.
Takeshi Shudo's novelizations depict the world of the anime as a Crapsack World, 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.
I bet you could use a Cresselia right about now, eh?
