History NightmareFuel / Pokedex

* While Hatenna will merely run away in order be left alone, Hattrem will actively and violently try to silence anyone who brings strong emotions near her by PUMMELING them with her braids which can knock out a professional boxer in a SINGLE PUNCH. Hatterene will straight up tear people apart with her claws if they're too loud.

[[folder:Seventh Generation Pokémon (#722-#802)]]

** Malamar gets another one in ''Shield'', reading: "It's said that Malamar's hypnotic powers played a role in certain history-changing events." If that's true, then... [[FridgeHorror what did it cause?]] What would've happened if it didn't aid those it was helping? Considering what the above said, about being used for nefarious schemes, could they have caused catastrophic events in the world? That is, if they even exist in the Pokémon world?

* Cofagrigus, Yamask's evolution, 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 it: in other words, ZombieApocalypse. According to its Pokédex entry, it pretends to be a fancy coffin so it can punish grave robbers. It's entry in ''Sword'' also states that, in contrast to Yamask weeping over its past life, Cofagrigus has completely forgotten that it was once human.

* Cofagrigus, Yamask's evolution, 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 it: in other words, ZombieApocalypse. According to its Pokédex entry, it pretends to be a fancy coffin so it can punish grave robbers.

* Gourgeist, the evolution of Pumpkaboo. Its ''Y'' dex entry states [[{{Sadist}} it sings joyfully while watching its prey suffer]].

* Despite its cute appearance, Vileplume is carnivorous. It uses toxic and hyper-allergenic pollen to paralyze its victims, then ''eats them.''

* Primeape is a [[IncrediblyLamePun prime offender.]] Pretty much every Pokédex entry mentions its Creator/JoePesci[[HairTriggerTemper -like tendencies]]. As in, it can be pissed off by pretty much anything.

Its ability, Mummy, gives the same ability to anyone hitting it: in other words, ZombieApocalypse. According to its Pokédex entry, it pretends to be a fancy coffin so it can punish grave robbers.

* Amoonguss uses its Poké Ball mimicry to lure prey, but Pokémon aren't usually fooled by it. Humans, on the other hand, might not know better...

** Jellicent's (Frillish's evolved form) ''Black'' Pokédex is highly 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. In ''Black 2 and White 2'', the Pokédex states that it has an undersea castle made from the remnants of 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.
** After Groudon/Kyogre's appearance in ''Omega Ruby'' and ''Alpha Sapphire'', Frillish start appearing in the [[MemeticMutation infamously]] water-heavy Hoenn, and ''Ultra Sun'' and ''Ultra Moon'' introduced them to the seas of Alola — there's even a small side quest where you have to save some Swimmers from them. Better hope they never become as common as they are in Unova, or those two regions could be in some serious trouble.
* 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 [[RunningGag Ghetsis also has one]]. It also has no weaknesses in the games. Its type's only weakness, Ground, is canceled out by its ability, Levitate.

** Litwick is a cute little Fire/Ghost candle, but the Pokédex 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". It's made even creepier in ''Black 2/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. That's right, kids — even ''your own'' Litwick will leech off your soul, so being its owner doesn't even make you safe! Made better by the fact that she goes to the Pokémon Center afterwards to rest, but it's still creepy.
*** The ''White 2'' entry outright states that, "Its flame is usually out, but it starts shining when it absorbs life force from people or Pokémon". Its sprite always has the flame lit. So either it's feeding on the Pokémon it faces, or Nate/Rosa are going to end up lethargic...
*** Which kinda makes it all sad, too, because it's possible [[PowerIncontinence it can't]] ''[[PowerIncontinence stop itself]]'' [[PowerIncontinence from draining the souls of living creatures]] (much like how Darkrai can't prevent itself from giving nightmares to anyone nearby), so the little Hinkypunk-based buddy might be unintentionally [[Franchise/HarryPotter Dementoring]] its beloved trainer. After all, you can max out your friendship with one just by levelling it up from a Litwick to getting its immediate evolved form Lampent to learn its last attack at level 69. Litwick are found in places where there aren't usually a lot of other living creatures apart from other Litwick, and Litwick is always the most common Pokémon in the area if it's not exactly equal to the rest. It's a toss-up to see if this is because Litwick have killed everything else[[note]]which begs the question of how three different Psychic Pokémon can live beside them despite being very weak to them and why they haven't evolved into Lampent or Chandelure[[/note]] or because they've purposely put themselves away from others so all they have are the souls of the already-deceased to eat (which makes sense, as the places they go are haunted) and others joined them because of one thing or another.
*** YMMV on whether this is better or worse, but evidently the souls they consume are neither [[AndIMustScream trapped within them]] nor [[CessationOfExistence destroyed]]; rather, they are [[BarredFromTheAfterlife stuck in limbo for eternity]].

* The Dark/Dragon line of Deino-Zweilous-Hydreigon starts with one head, grows a second one as 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.
** 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. According to its dex entry, "The heads on its arms lack brains." One of the heads loses its ''[[DeathOfPersonality brain.]]'' Alternatively, its brains merge and it's driven insane, accounting for its "brutal" nature. Even better (or worse), wild ones will SWOOP AT YOU FROM OUT OF NOWHERE on the Kalos Victory Road. And to make things even more worse, [[RunningGag it's another creepy Pokémon that Ghetsis has in his possession]]. [[WeaponOfChoice It's the cornerstone of his team.]]
* While Volcarona is mentioned as having been deified as a bringer of light, it still is an enormous (as in, 5 feet tall and weighing a ''hundred pounds'') 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. One has to wonder what would happen if Volcarona encountered anything WeakenedByTheLight...

* Kyurem. Apparently, it would actually hunt and consume humans and Pokémon alike. Worse still, it's a Legendary.
** It gets worse in ''VideoGame/PokemonBlack2AndWhite2''. You know its badass new formes of Black/White Kyurem? They're caused by Kyurem [[AndIMustScream turning Reshiram/Zekrom back into the Light/Dark Stone]] and [[TheAssimilator using them as mere powerups]] [[FusionDance for itself]]. And if that isn't enough, it turns out that the fusion isn't even a complete one, since N outright says [[AndIMustScream 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). This is particularly scary if you watch the fusion cutscene, and makes you shed a tear or two for N's poor dragon. ''And'' it makes you [[YouBastard feel guilty afterwards]] if you capture N's dragon and Kyurem and want to recreate Kyurem's new forme. Slightly subverted in that Kyurem and the other two dragons were once one being, and Kyurem is just trying to become whole again.

** It gets worse when you consider why it might have gone extinct in the first place. 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.
** Genesect, as a Mythical Pokémon, has no real residence like most Legendaries, so it's not unlikely that it roams the planet. If its instincts and nature haven't changed much post-upgrade[[labelnote:*]]or have gotten ''worse'', considering the group that revived it[[/labelnote]], woe be to anyone living near wherever it may currently be...

* 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.

\n
In fact, several of Paras' entries identify the fungus as the tochukaso, which is a subspecies of the real-life cordyceps fungus. Be our guest and look it up, but depending on how you feel about BodyHorror, you may want to keep a vomit bag handy.

* Bug Pokémon. While Misty's phobia of bug Pokémon is PlayedForLaughs in the anime, the fact of the matter is that they are often [[BigCreepyCrawlies at least the size of car tires]].
* The [[FeatheredFiend flying-type birds]] are the counterparts of pigeons, 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 ''Film/TheBirds'' 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 GiantFlyer ones.

* Nidorino's horn is "strong enough to pierce diamonds", and he's a Poison-type.

* 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.

** You wanna know the worst part? This type of thing [[TheFourthWallWillNotProtectYou happens to real insects.]] [[https://www.youtube.com/watch?v=XuKjBIBBAL8 Case in point...]]
*** In fact, several of Paras' entries identify the fungus as the tochukaso, which is a subspecies of the cordyceps fungus. Be our guest and look it up, but depending on how you feel about BodyHorror, you may want to keep a vomit bag handy.
** You know what? The cordyceps' real-life victims have it easy — if nothing else, the fungus will eventually kill them off. And then there's Parasect, who, for all we know [[AndIMustScream could still be alive and possibly even aware of what's happening to it.]]
** Can we just take a moment to appreciate the fact that this is ''Parasect'' we're talking about here? You know, that innocuous little thing that you always just glanced over as a kid because Scyther and Pinsir looked cooler? The one you had no idea was basically possessed? ''That'' Parasect? Well, good luck '''ever''' looking at it the same way again.

*** [[FridgeHorror It is possible that Machoke's bulging, overextended muscles are]] [[BodyHorror the early phase of its arms splitting apart before evolution.]]
* Bellsprout's Generation I [[http://archives.bulbagarden.net/media/upload/8/86/Spr_1b_069.png sprite]] looks like a skull on a plant.
** 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''.
** 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". Suddenly, James's RunningGag of being eaten by his Victreebel in the anime doesn't sound that funny, isn't it?
*** Also, its hunting method is... disturbing. Taken from its ''Soul Silver'' entry: "This [[LampshadeHanging horrifying]] plant Pokémon attracts prey with aromatic honey, then melts them in its mouth." Not to mention it's based off of a real plant that hunts with this exact same method.

* Hypno, a Child[[spoiler:'s Dream]]-Eating Pokémon. It leads children away by hypnotizing them and they're never seen again. [[MemeticMolester The child abduction/molestation undertones are rampant]] (even the anime did an episode about it; it was toned down, of course, but that doesn't make it any better). There [[http://i99.photobucket.com/albums/l302/Chris_Lv255/hypno062608.png is an official shirt that plays on this, featuring a photorealistic Hypno leading away silhouettes of actual children]]. And a [[https://www.youtube.com/watch?v=FT_ZpHgiIKo song]], courtesy of {{Creepypasta}}.

* Voltorb and Electrode [[ChestMonster 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.

** One possible explanation is that it comes with a skull at birth. But when its mom dies, it replaces its natal skull with [[TragicKeepsake its mother's skull]] to never forget her. Considering how most of the entries take about how it never stops [[TheEeyore crying about its lost mother]], this would actually [[FridgeBrilliance make a lot of sense]].

* Starmie's Pokédex entries suggest that it might be an alien species and that its core sends radio signals into space. Then there's the fact that Staryu and Starmie are among the very, '''very''' rare Pokémon with virtually nothing in their appearance to mark them as living creatures: no eyes, no mouths... for all intents and purposes, they look like inanimate objects with a jewel for a core. StarfishAliens taken to a literal and rather unsettling extent.
* [[https://www.youtube.com/watch?v=-7ZV8AN-lJ0 Mr. Mime's laugh]] in ''Pokémon Stadium''.

* Crobat, Golbat's evolved form, is rather creepy itself, being a 5 feet, 11 inches tall, 165-pound blood-sucking bat. ''Thankfully'', they can't be found in the wild until Generation V...
* Igglybuff's unsettling, enormous red eyes add an unnerving edge to an otherwise adorable Pokémon.

* 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 ''[[{{Hellfire}} 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 RealLife.
** Downplayed by [[http://bulbapedia.bulbagarden.net/wiki/EP180 one particular episode]] where a Houndoom went out of its way to help Misty's Togepi find its way back to Ash and company, protecting it and developing a bond with it on the way.
* Larvitar's Pokédex entry:
--> ''"A Pokémon that eats soil. Once it has eaten a large mountain, it goes to sleep so it can grow."''
** Larvitar and its evolution 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.
** The final evolution, Tyranitar, is strong enough to make entire mountains crumble: after one goes on a rampage, "maps have to be redrawn to account for the damage".
* 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 Pokémon 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 [[http://i73.photobucket.com/albums/i214/mountaindoozie/Lugia.jpg Lugia.]]
** And, to make Lugia even scarier? Meet [[http://i615.photobucket.com/albums/tt232/ZeroZilla67/shadow_lugia.jpg Shadow Lugia]]. It's basically a Lugia forcibly turned "evil" by turning it 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 [[Anime/{{Pokemon2000}} the second movie]], when another one serves as a guardian to Shamouti island.

* 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-lamprey'' [[HumanoidAbomination than other humanoid Pokémon]].
** Starting from Gen VI, Gardevoir is also Fairy-type. If that seems to lessen the effect, [[TheFairFolk fairies weren't always cute little winged harmless things.]] It's a good thing it wants to protect you rather than play nasty pranks or worse.

* Gulpin and Swalot play on the PrimalFear 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.
** Yes, there ''is'' [[https://funnyjunk.com/channel/pokemon/Pokemon+comp+e/DzdYLQm/51 vore art depicting Swalot.]] If you value your ability to sleep at night, it's best not to look at it.

* 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.

* 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.
* 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.

* Latios and Latias are found in the game carrying the item Soul Dew, which increases their stats. In the movie ''Anime/PokemonHeroes'', it's discovered that the Soul Dew is actually made from the soul of a dead Lati. So the Lati seen in the games [[SoulJar is carrying around a trapped soul to make it stronger]].

* 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.
* Drifloon, a cutesy balloon Pokémon, [[http://debureturns.deviantart.com/art/Drifloon-106464127 apparently]] tries to drag people to the underworld ([[NightmareRetardant but is so weak that it gets dragged along like a common balloon you see at birthday parties]]).
** For Drifloon, it was made [[SarcasmMode so much better]] in ''Sun and Moon''’s Pokédex entries:
--> '''''Sun'' Pokédex:''' Stories go that it grabs the hands of small children and drags them away to the afterlife. It dislikes heavy children.\\
'''''Moon'' Pokédex:''' If for some reason its body bursts, its soul spills out with a screaming sound.
** Drifblim, its evolution, is more successful at carrying kids off into the land of the dead.

* Froslass, Glalie's evolution counterpart, is based on the yuki-onna, a type of ghostly Yōkai 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. Because of this, there's the implication that Froslass is not above having sex with her victims before said actions (or it would, if this wasn't a family-friendly video game).
** There's also the fact that, in order to get a Froslass, you need to evolve a female Snorunt (an Ice type) by exposing it to a Dawn Stone. Froslass is an Ice/Ghost type, so this means that she melted.
** And then there's her Pokédex entry...

*** This gets ''explicitly shown'' in ''VideoGame/PokemonMysteryDungeonExplorersOfTimeAndDarkness''. Poor Scizor...
* Regigigas, the Regi "boss", has been rumored to move entire continents. In Platinum, the fact that he is encountered at Level 1 makes it NightmareRetardant.

*** One of the most infamous owners of Cofagrigus is Ghetsis. The best it can hope for is [[PragmaticVillainy for Ghetsis to treat it well so that it's a powerful ally.]] [[FridgeHorror But considering who he is...]] [[UpToEleven and that's not even getting into]] [[AndIMustScream what Cipher would do.]]

** 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. According to its dex entry, "The heads on its arms lack brains." [[FridgeHorror One of the heads loses its]] ''[[DeathOfPersonality brain.]]'' Alternatively, its brains merge and it's driven insane, accounting for its "brutal" nature. Even better (or worse), wild ones will SWOOP AT YOU FROM OUT OF NOWHERE on the Kalos Victory Road. And to make things even more worse, [[RunningGag it's another creepy Pokémon that Ghetsis has in his possession]]. [[WeaponOfChoice It's the cornerstone of his team.]]

* Honedge, a possessed sword. Looks like an EquippableAlly, right? Wrong! In fact, it is an ArtifactOfDeath that punishes those who try to invoke it; those who dare to wield Honedge like a sword will find its tassel wrapped around them and sucking their life force dry. [[FridgeHorror Now]] ''[[FridgeHorror how]]'' [[FridgeHorror would 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 ruthless leaders.

* Inkay and Malamar in ''X and Y''. To boot it off for a start, they are the first Pokémon to be typed [[DarkIsEvil Dark]]/[[PsychicPowers Psychic]]. They are {{Cthulhumanoid}}s who have the power to [[MindManipulation control others]]. And it's implied that people have tried to use them in the past for their own nefarious schemes. [[FridgeHorror Try not to think about that too hard.]]
** In the anime, one — a wild one uncontrolled by humans at that — wants to [[ApocalypseHow destroy the entire world with a virus that renders it fit only for Inkay and Malamar to live on.]] [[VideoGame/{{Splatoon}} Sound familiar?]]

** It can spit [[PoisonIsCorrosive acidic poison]] that's able to melt through the steel hull of a ship ([[GameplayAndStorySegregation And yet it has no effect on Steel-type Pokémon]]). [[FridgeHorror Imagine]] what it would do to a human or a Pokémon.

** And the fact that the Pokédex knows that this will happen implies that [[FridgeHorror it has happened before.]] Anyone notice how empty the Kalos region is in terms of unique Pokémon? Or how a good chunk of the Pokémon are ghosts... [[FantasticNuke it's happened before, killing everything in the region, removing the original species.]] All the Pokémon in the game are either new species, legendary, or imported from different regions.

* Bounsweet is certainly a cute Pokémon that's also relatively harmless, but what about the dex entry in ''Sun'' where it says it is often ''[[SwallowedWhole swallowed whole]]'' by other Pokémon? Or the entry in ''Ultra Moon'' where it says it tries to resist this fate by spinning its sepals (usually without success)? And it's all thanks to [[BlessedWithSuck its sweet-smelling scent it constantly produces]]. The best part about it is that [[NothingIsScarier we aren't told what happens to the Bounsweet]] [[FridgeHorror after it's been swallowed]].

* [[WhyDidItHaveToBeSnakes Ekans and Arbok]] [[ReptilesAreAbhorrent are pretty much giant, poisonous snakes.]] It's a cobra and a python mixed into one frighteningly lethal package.

* 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.

* Wobbuffet (plus its Gen III pre-evolution Wynaut) is cute, funny, and, starting from Gen III, [[LethalJokeCharacter surprisingly]] [[GameBreaker awesome]]. But the issue 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 Wobbuffet looks and acts like an inflatable punching bag, because it actually is (and, in the ''VideoGame/SuperSmashBros'' games, it acts exactly as such). The 'eye spots' 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.

* Scyther's evolution, Scizor, is pretty much the same, but is coated in metal armor and has ''metal pincers for hands''. Ouch.

* Aggron (a fellow beastly-looking Pokémon who's a bipedal metal Triceratops) lives around mountains and will savagely protect its territory from all comers, and repairs any damage to its home.

* [[WhyDidItHaveToBeSnakes Seviper]]: same deal as with Ekans and Arbok, [[ReptilesAreAbhorrent a giant, poisonous snake.]]

* 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 Pokédex entry of it being formed during the Ice Age.

* As if the Pokédex was not already dark enough, ''VideoGame/PokemonSunAndMoon''[='=]s Pokédex has entries that would top even the most graphic entries from previous generations.

* Magneton: the Pokédex says that 3 Magnemite join together to form one of these. However, GameplayAndStorySegregation 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.

* 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 [[DittoFighter transform]], Ditto might well be a failed clone of Mew (which explains why it's a melted blob).

** The ''Ultra Sun'' dex entry describes it as "vicious". It also says it [[NightmareRetardant gets along]] [[OddFriendship very well]] with Dhelmise.

** One possible explanation is that it comes with a skull at birth. But when its mom dies, it replaces its natal skull with its [[TragicKeepsake its mother's skull]] to never forget her. Considering how most of the entries take about how it never stops [[TheEeyore crying about its lost mother]], this would actually [[FridgeBrilliance make a lot of sense]].

* Regigigas, the Regi "boss", has been rumored to move entire continents.

[[Franchise/{{Pokemon}} 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 InUniverse rumours and stories, and thus should be taken with a grain of Shoal Salt.

** The most horrifying thing about them isn't the fact that they're horrendously strong, but by how just ''existing'', they are a WalkingDisasterArea. [[spoiler:The previously-mentioned purpose of Type: Null turns out to be fighting them off.]] Two Ultra Beasts stand out in terms of the havoc they wreak: Celesteela, which is basically a ''huge bamboo rocket mecha'' who causes firestorms ''just by moving normally'' due to the exhaust from its rockets, and Guzzlord, ''who never stops eating and once ate an entire ocean'' ([[spoiler:and is heavily implied to have eaten a woman who was originally part of Looker's beast-stopping team]]), and can convert anything it ate so perfectly, '''there is no waste.''' It's even more terrifying to think just what kind of places would require anything to evolve into things like these.

** Its ''Sun'' Dex entry tells how it came from another world in ancient times. Sounds just like Solgaleo and Lunala, doesn't it? Which raises the question; just ''when'' did it come, and what did it do when it arrived given the aforementioned vicious nature? Is it related to Cosmog?
* Bounsweet is certainly a cute Pokémon that's also relatively harmless, but what about the dex entry in ''Sun'' where it says it is often ''[[SwallowedWhole swallowed whole]]'' by other Pokémon?

* Giratina was banished to [[{{Hell}} another dimension]] for its extremely violent nature by [[{{God}} Arceus.]] During its time in that dimension, its presence reformed the dimension into the [[MirrorUniverse Distortion/Reverse World.]] In its home world, Giratina "silently gazed upon the old world" through [[ParanoiaFuel reflective objects, such as mirrors and still pools of water.]] Until recently, it can be seen appearing in an ancient cemetery, said cemetery being the entrance to his home dimension. So there you have it, a violent, 22'08" tall SatanicArchetype can appear anytime into the real world when it's not grudgingly watching you from its [[EldritchLocation home dimension.]] There's no way of killing it since it's [[{{Dracolich}} already dead (Ghost-Type).]]

* 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 do it on purpose or out of malice; it's a defense mechanism that it can't control.
** 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.

* Seismitoad 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 [[OverlyLongGag Ghetsis has one.]]

* Yamask's Black Pokédex entry says that the mask on its sprite is actually its former human face, and the Pokémon weeps over memories of being alive. It was apparently born from the spirit of someone buried in an ancient grave.
** Cofagrigus, its evolution, 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, ZombieApocalypse. According to its Pokédex entry, it pretends to be a fancy coffin so it can punish grave robbers.

* Archeops may be [[{{Adorkable}} endearingly pitiful]], but its Black Pokédex entry shows that it's a clear case of NotSoHarmless: "They are [[ItCanThink intelligent]] and [[ZergRush will cooperate to catch prey]]. From the ground, they use a running start to take flight." And according to other Pokédex entries, it can [[SuperSpeed run 25 miles per hour]]. Oh, and the Moon Pokédex entry for it states that "when one Archeops had the prey cornered, another would swoop on it". That's right: Archeops are basically the Pokémon equivalent to the ''Velociraptors'' from ''Franchise/JurassicPark''... but unlike those raptors, Archeops can ''fly''...
* 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 [[YouWillNotEvadeMe Shadow Tag]] and its pre-evolved form is known for obsessively staring at people. The final evolution in the line, Gothitelle, manages to be creepy in a [[AdultFear different]], [[TearJerker heartbreaking]] way, as it's perfectly capable of determining someone's lifespan through the stars. The B&W2 entry specifically notes that it starts crying once it discovers how long its Trainer has.

** Jellicent's (Frillish's evolved form) 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. In ''Black 2 and White 2'', the Pokédex states that it has an undersea castle made from the remnants of 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.
** After Groudon/Kyogre's appearance in ''Omega Ruby'' and ''Alpha Sapphire'', Frillish start appearing in the [[MemeticMutation infamously]] water-heavy Hoenn, and ''Ultra Sun'' and ''Ultra Moon'' introduced them to the seas of Alola - there's even a small side quest where you have to save some Swimmers from them. Better hope they never become as common as they are in Unova or the two regions could be in some serious trouble.

** 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". It's made even creepier in ''Black 2/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. That's right, kids — even ''your own'' Litwick will leech off your soul, so being its owner doesn't even make you safe! Made better by the fact that she goes to the Pokémon Center afterwards to rest, but it's still creepy.
*** The White 2 entry outright states that, "Its flame is usually out, but it starts shining when it absorbs life force from people or Pokémon". Its sprite always has the flame lit. So either it's feeding on the Pokémon it faces, or Nate/Rosa are going to end up lethargic...
*** Which kinda makes it all sad, too, because it's possible it can't ''help'' but suck out souls with so many living creatures (much like how Pichu can't help but shock itself when it uses its abilities), so the little Hinkypunk-based buddy might be unintentionally [[Franchise/HarryPotter Dementoring]] its beloved trainer. After all, you can max out your friendship with one just by levelling it up from a Litwick to getting its immediate evolved form Lampent to learn its last attack at level 69. Litwick are found in places where there aren't usually a lot of other living creatures apart from other Litwick, and Litwick is always the most common Pokémon in the area if it's not exactly equal to the rest. It's a toss-up to see if this is because Litwick have killed everything else (which begs the question of how three different Psychic Pokémon can live beside them despite being very weak to them and why they haven't evolved into Lampent or Chandelure), or because they've purposely put themselves away from others so all they have are the souls of the already-deceased to eat (which makes sense as the places they go are haunted) and others joined them because of one thing in another.
*** YMMV on whether this is better or worse, but evidently the souls they consume are neither trapped within them nor destroyed; rather they are [[BarredFromTheAfterlife stuck in limbo for eternity]].

* 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!
* Heatmor's dex entry. It grabs a Durant, blows fire on it until the heat melts its exoskeleton into metallic goo, 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 ArchEnemy is a fire-type anteater, akin to the Zangoose/Seviper rivalry and Zangoose's Immunity.
* Durant: Ants that are thirty centimetres tall (roughly 11 inches), with steel covered skin that would make it nigh impossible to stomp on them.
* The Dark/Dragon line of Deino-Zweilous-Hydreigon starts with one head, grows a second one as 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.
** 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. According to its dex entry, "The heads on its arms lack brains." [[FridgeHorror One of the heads loses its]] ''[[DeathOfPersonality brain.]]'' Alternatively, its brains merge and it's driven insane, accounting for its "brutal" nature. Even better (or worse), wild ones will SWOOP AT YOU FROM OUT OF NOWHERE on the Kalos Victory Road. And to make things even more worse, [[RunningGag it's another creepy Pokémon that Ghetsis has in his possession]]. It's the cornerstone of his team.

** It gets worse in ''VideoGame/PokemonBlack2AndWhite2''. You know its badass new formes of Black/White Kyurem? They're caused by Kyurem [[AndIMustScream turning Reshiram/Zekrom back into the Light/Dark Stone]] and [[TheAssimilator using them as mere powerups]] [[FusionDance for itself]]. And if that isn't enough, 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). This is particularly scary if you watch the fusion cutscene, and makes you shed a tear or two for N's poor dragon. AND it makes you [[YouBastard feel guilty afterwards]] if you capture N's dragon and Kyurem and want to recreate Kyurem's new forme. Slightly subverted in that Kyurem and the other two dragons were once one being, and Kyurem is just trying to become whole again.

* Honedge, a possessed sword. Looks like an EquippableAlly, right? Wrong! In fact, it is an ArtifactOfDeath 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. [[FridgeHorror Now]] ''[[FridgeHorror how]]'' [[FridgeHorror would 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 ruthless leaders.
** 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 either: bristles furiously and makes as if to unsheath itself if it loves you, or takes pleasure in sucking you dry if it's a stranger to you. Doublade is much more easygoing.
* Inkay and Malamar in X and Y. To boot it off for a start, they are the first Pokémon to be typed [[DarkIsEvil Dark]]/[[PsychicPowers Psychic]]. They are {{Cthulhumanoid}}s who have the power to [[MindManipulation control others]]. And it's implied that people have tried to use them in the past for their own nefarious schemes. [[FridgeHorror Try not to think about that too hard.]]

* Trevanant is based on a kodama, a type of spirit that inhibits trees. Not only does it have menacing looks, but it can trap people who harm the forest so that it can never leave.

** Its pre-evolution, Phantump, is scary for a completely different reason: the dex entry states that they are the ''ghosts of children'' who got lost in the forest.

* While Xerneas may seem like the benevolent counterpart to Yveltal, after hearing about the extent of it's life-giving abilities, you'll be ''thankful'' that Yveltal's around to help balance it out. Xerneas is capable of sharing everlasting life. As in ''immortality.'' While this may seem like a good thing, keep in mind that Pokemon X & Y have two characters who became immortal due to the use of the Ultimate Weapon, those being AZ and the Eternal Floette, and up until their reunion, they were both miserable because of it. The former of which [[WhoWantsToLiveForever has been wandering the region for centuries unable to die,]] and the latter [[ImmortalityHurts has already experienced the pain of dying before.]] The worst part? In Pokemon X Version, as a last-ditch attempt after beating him, Lysandre plans on using the Ultimate Weapon (which had been sapping Xerneas's power) to curse both you and your friends with immortality.
* And rounding out the Kalos Legendary Trio is Zygarde, who is single-handedly the most bizarre and otherworldly Pokémon in existence. It is a Pokemon [[TheWormThatWalks composed of numerous Cells and Cores]] that [[TookALevelInBadass take on stronger and more disturbing forms the more cells it has.]] At 10% of its power, it resembles an alien doberman dog. In its default 50% form, it resembles a monstrous serpentine creature. And then there's its Complete Form, which is a {{Kaiju}}-sized HumanoidAbomination with a BellyMouth, a tail, and four cape-like wings. However, according to the Pokédex, it's actually a GentleGiant that is quite content to be left alone... [[BerserkButton until you mess with the environment.]] [[GaiasVengeance That's when things get really ugly.]]
** Despite its Complete Form being its most powerful form, [[GodzillaThreshold Zygarde thankfully only uses this form when its back is to the wall and there's no other choice.]] Episode 43 of the XY anime finally showcases just how powerful it is in this form and... Well, let's just say [[spoiler:[[BigBad Lysandre]] [[KilledOffForReal learned the hard way]]]] that it's '''''never''''' a good idea to mess with a force of nature.

* A walking volcano is a terrifying thought, right? Well, meet Volcanion, a [[PerpetualFrowner nigh-perpetually pissed off]] creature with enough power to blow up an entire mountain. And if its personality in [[Anime/PokemonVolcanionAndTheMechanicalMarvel its movie]] is reflective of its personality in the games, it doesn't like humans one bit. Thankfully, it keeps to itself within mountains away from mankind, but it's not hard to imagine what it'd do to a human settlement if it was pissed off with one.

** If you want an extra layer of horror, the dex entry for Moon says that inside Palossand you can find the ''dried-up bones of its past victims''.

* Female Salandit can produced pheromones that can hypnotize humans and Pokémon alike. Then it becomes Salazzle, who travels everywhere with a "reverse harem" of hypnotized male Salandit. It's basically the Pokémon equivalent of a ''[[HornyDevils Succubus]]''.
* Wishiwashi. Tiny little fish that according to Pokédex entries, are cowards, weaklings, and [[BreadEggsMilkSquick tasty]]. However, they have the Ability Schooling, which makes them gather in great numbers until they form a giantic, scary-looking fish with multiple GlowingEyesOfDoom. According to the Pokédex entry, even ''[[HorrifyingTheHorror Gyarados]]'' are scared of school form Wishiwashi.

*** That's subverted when you find that Type: Null's owner, Gladion, is hardly considered a true member of Team Skull. However, [[spoiler:when you go to the Aether Foundation to rescue Lillie, you can find out many things concerning Type: Null (then called Type: Full), including the fact that the artificial Pokémon went berserk when scientists of the Aether Foundation tried to force the RKS System into it, causing it to go berserk and the project to be deemed a failure. Since then, only three were made, with Gladion stealing one and running from the foundation's president and his mother, Lusamine, with the other two remaining in cryogenic sleep.]]

* Tapu Lele. It's an [[RidiculouslyCuteCritter adorable little pink, feminine, butterfly creature]] with a curious nature that stopped an entire war just by soothing the warriors with its rejuvenating scales. [[TemptingFate Not scary at all, right?]] Well, for starters, despite its appearance, the Pokédex states that it is "guilelessly cruel". Its scales, while very useful for healing, can be very dangerous if taken in large amounts, ''[[ItAmusedMe and it scatters them everywhere]] [[JerkassGods on a whim]]''. And that part where it stopped a war by healing the warriors?? That's just one side of the story. [[spoiler:This thing has destructive capabilities rivaling even ''Yveltal''. While the English website for ''Sun and Moon'' simply states that it stopped the war by healing the soldiers, the Japanese website reveals a horrifying truth: contrary to popular belief, it actually ended the war by ''[[FinalSolution killing all the soldiers]]'' with its dangerous scales.]]

** The most horrifying thing about them isn't the fact that they're horrendously strong, but by how just ''existing'' they are a WalkingDisasterArea. Even more so with Celesteela, which is basically a ''huge bamboo rocket mecha'' who causes firestorms ''just by moving normally'' due to the exhaust from its rockets, and Guzzlord, ''who never stops eating and once ate an entire ocean'' ([[spoiler:and is heavily implied to have eaten a woman who was originally part of Looker's beast-stopping team]]), and can convert anything it ate so perfectly, '''there is no waste.''' It's even more terrifying to think just what kind of places would require anything to evolve into things like these.
*** Nothing natural, that's for certain.. The horror of Guzzlord [[spoiler:or more specifically, where they originate from,]] is expanded upon in ''VideoGame/PokemonUltraSunAndUltraMoon'', when you visit [[spoiler:their home dimension, the Ultra Ruin, which is itself implied to be an alternate universe Hau'oli City. From gathering information, it's heavily implied that a power plant suffered a disaster of apocalyptic proportions, destroying the world. Whether Guzzlord arose from this disaster, was specifically created to deal with the fallout, or somehow already existed is unknown, but while the place was so mutilated the inhabitants seemingly had to be evacuated to other ''planets'', the Ultra Beasts were left behind to devour the remains. Even worse for the planet, the same person notes the numbers of Guzzlord have been decreasing as of late. In other words, they've destroyed the world so thoroughly that there's nothing left for [[ExtremeOmnivore even them]] to eat, let alone for any hope for any other type of life.]]

* [[WhyDidItHaveToBeSnakes Ekans and Arbok]] [[ReptilesAreAbhorrent are pretty much giant, poisonous snakes.]] It's a cobra and a python mixed into one lethal package.

*** [[FridgeHorror It is possible that Machoke's bulging, overextended muscles are the]] [[BodyHorror early phase of its arms splitting apart before evolution.]]

** [[http://www.suruga-ya.jp/database/pics/game/978006477.jpg This promotional photo]] for ''Anime/PokemonTheFirstMovie''. Notable in that it depicts Mewtwo with his mouth open (and Pikachu with no mouth), despite the fact that he never does so in the actual movie. Which makes the image all the creepier.

* Wobbuffet (plus its Gen III pre-evolution Wynaut) is cute, funny, and, starting from Gen III, [[LethalJokeCharacter surprisingly]] [[GameBreaker 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 ''VideoGame/SuperSmashBros'' games, it acts exactly as such). The 'eye spots' 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.

* Larvitar's Pokedex entry:

* 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 [[http://i73.photobucket.com/albums/i214/mountaindoozie/Lugia.jpg Lugia.]]
** And, to make Lugia even scarier? Meet [[http://i615.photobucket.com/albums/tt232/ZeroZilla67/shadow_lugia.jpg 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 [[Anime/{{Pokemon2000}} the second movie]], when another one serves as a guardian to Shamouti island.

** 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.
** 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".

* Shedinja looks like a cicada skin, but, according to legend, 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.
* 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. [[EyeScream Sadly, doing the math is not for the best here.]]

* Carvanha and Sharpedo: the former can tear through boat hulls and attack in swarms while the latter can destroy a supertanker with its sharp teeth; now imagine coming face to face with them.

* 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.

* Glalie freezes its victim, not unlike Froslass, but instead of being displayed like a trophy of some sort, the poor creature is ''eaten''. And to top it off, some of Glalie's entries state that it does such in "a leisurely fashion", possibly implying that either Glalie does this even when it isn't feeling particularly peckish or doesn't experience hunger at all and just does this for kicks and giggles.

* 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".

** For Drifloon, it was made [[SarcasmMode so much better]] in Sun and Moon's Pokédex entry:
--> '''Sun Pokedex:''' Stories go that it grabs the hands of small children and drags them away to the afterlife. It dislikes heavy children.\\
'''Moon Pokedex:''' If for some reason its body bursts, its soul spills out with a screaming sound.

* 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 were the only combination that's not weak to any attack until Fairy-type was introduced.

* The entire idea of having "[[OurGhostsAreDifferent Gho]][[SoulPower st]]" as an elemental type is creepy. If their dex entries are to be believed, most of them are at least linked to afterlife in some ways, if not outright rumored to be dead people in Pokémon forms (as in the case of Yamask and Phantump, for instance). This puts a whole new spin to the very idea of the game, in that you aren't just capturing wild animals and use them in battle, but ''capturing souls of the dead or harbingers of afterlife or such and use them in battle'', and that's highly disturbing. It's no coincidence that ghost-types are disproportionately likely to be on this list.

* [[WhyDidItHaveToBeSnakes Ekans and Arbok]] [[ReptilesAreAbhorrent which are pretty much giant, poisonous snakes.]]

** You know what? The cordyceps' real-life victims have it easy - if nothing else, the fungus will eventually kill them off. And then there's Parasect who for all we know [[AndIMustScream could still be alive and possibly even aware of what's happening to it.]]

* Primeape is a [[IncrediblyLamePun prime offender.]] Pretty much every Pokédex entry mentions its Creator/JoePesci[[HairTriggerTemper -like]] tendencies. As in, it can be pissed off by pretty much anything.

* [[http://www.serebii.net/pokedex-rs/060.shtml Poliwag's]] cute spiral is, in fact, its [[{{Squick}} internal organs]], which can be seen though its skin (much like actual tadpoles). However, when evolving, the swirl changes direction.

--> ''"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. In fact, the Pokédex entries for Mega Alakazam confirm that it moves exclusively through telekinetic power because ''its muscles have completely atrophied''.
* [[http://bulbapedia.bulbagarden.net/wiki/Machoke_(Pokémon) 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.

** 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''.

*** Also, its hunting method is... disturbing. Taken from its Soul Silver entry: "This [[LampshadeHanging horrifying]] plant Pokémon attracts prey with aromatic honey, then melts them in its mouth." Not to mention it's based off of a real plant that hunts with this exact same method.

* Doduo and Dodrio seem okay at first glance--Doduo is a cute little ostrich-like bird with two heads, and Dodrio, its evolved form, as a more angry looking bird with three heads. But how does it get the third head? According to the Pokedex, one of its two heads ''[[BodyHorror splits in two!]]''
* 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 poisoned 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.

** Haunter, in the manga, had a tendency to use its Dream Eater attack to steal people's souls. Haunter's Pokedex entries in the games imply he's an EldritchAbomination slowly killing whoever it wants to kill.

-->'''Sun:''' "Should you feel yourself attacked by a sudden chill, it is evidence of an approaching Gengar. There is no escaping it. Give up."

* Hypno, a Child[[spoiler:'s Dream]]-Eating Pokémon. It leads children away by hypnotizing them and they're never seen again. The child abduction/molestation undertones are rampant (even the anime did an episode about it. It was toned down, of course, but that doesn't make it any better). There [[http://i99.photobucket.com/albums/l302/Chris_Lv255/hypno062608.png is an official shirt that plays on this, featuring a photorealistic Hypno leading away silhouettes of actual children]]. And a [[https://www.youtube.com/watch?v=FT_ZpHgiIKo song]], courtesy of {{Creepypasta}}.

* Starmie's Pokedex entries suggest that it might be an alien species and that its core sends radio signals into space. Then there's the fact that Staryu and Starmie are among the very, '''very''' rare Pokémon with virtually nothing in their appearance to mark them as living creatures: no eyes, no mouths, for all intents and purposes they look like inanimate objects with a jewel for a core. StarfishAliens taken to a literal and rather unsettling extent.

* Gyarados is infamous [[InUniverse 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.

* Kabutops' Soul Silver's Pokédex entry managed to make it outright horrifying. To clarify, [[http://cdn.bulbagarden.net/upload/2/29/141Kabutops.png Kabutops]] is a vampiric 4-foot tall bipedal horseshoe crab with scythes for arms.

--> ''[[ForScience "We dreamed of creating the world's strongest Pokémon...]] [[GoneHorriblyRight and we succeeded."]]''
** 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 scientist says they couldn't curb its viciousness) is enough to be creepy. Even worse - said scientist is implied to be Dr. Fuji, as seen in pictures in the Pokémon Lab and Blaine's Gym. Dr. Fuji, meanwhile, is implied to be [[spoiler:''Mr.'' Fuji. Yes, that sweet old man in Lavender Town who cares for orphaned Pokémon? It's very possible that once upon a time, ''he performed horrible DNA experiments to create Mewtwo'']]. and the TruerToTheText ''Anime/PokemonOrigins'' ''confirms'' all that. This is perhaps even worse for him than in the regular animé, since unlike there, [[MyGodWhatHaveIDone he lives with the knowledge of what he's created]].

* Crobat, Golbat's evolved form, is rather creepy itself, being a 5 feet, 11 inches tall, 165-pound blood-sucking bat. ''Thankfully'' they can't be found in the wild until Generation V...

* Gligar looks like an UglyCute 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.

* Elgyem, the alien Pokémon. 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.

* Crobat, Golbat's evolved form, is rather creepy itself, being a 5 feet, 11 inches tall, 165-pound blood-sucking bat. ''Thankfully'' they can't be found in the wild... until Generation V...

* Crobat, Golbat's evolved form, 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...
