Summary

  • Hattrem, a Psychic-type Pokemon, has the ability to emit powerful psychic energy that can cause intense headaches to deter others from approaching.
  • Milcery, known for its cream topping, has cream that is packed with ultranutrients. When it evolves into Alcremie, the flavor of its cream changes.
  • Cofagrigus, a Ghost-type Pokemon, has a dark ability. It has been rumored that it swallows those who come too close to its mouth and turns them into mummies.

While the world of Pokemon is most well known for its adorable electric mouse mascot, Pikachu, the Pokedex is home to several unexpectedly dark entries that add depth to its seemingly colorful and fun world by highlighting the cruelty and horror of the series.

From stealing souls to committing acts of violence for violence’s sake, some Pokemon naturally wreak havoc on the world around them, leading many to their doom. Still, whether their actions are intentional or not, trainers may want to think twice about adding these Pokemon to their team after realizing what they are capable of outside of battle.

Updated on January 15, 2025, by Ben Painter: With over 1,000 Pokemon in the franchise currently, there are bound to be some unsettling Pokedex entries, especially those involving Ghost-type Pokemon. But it doesn't stop there; even the most innocent of Pokemon have a dark secret hiding away. These entries can range from being creepy to downright depressing, and each Pokemon has a unique one for fans to familiarize themselves with. For those brave enough, this article has been updated to feature even more of the most horrifying Pokedex entries across the Pokemon games.

45 Vespiquen

National Dex Number: #0416

Vespiquen In The Pokemon Anime
  • "Commands its subjects to build its hive. It will dispatch any interlopers who dare sneak into its nest and use them as nourishment for itself."

The Beehive Pokemon evolves from a female Combee and, just like its real-life counterpart, the queen bee, has some disturbing character traits. The worst one of these is described in its Pokemon Legends: Arceus Pokedex entry, which states that it will eat anyone who disturbs its hive.

The thought of Pokemon killing and eating each other is very unsettling, as they are all lovable creatures, and the act is never shown in the family-friendly franchise. Most of its other Pokedex entries say that it uses pheromones to command Combee to do its bidding.

44 Malamar

National Dex Number: #0687

Malamar In The Pokemon Anime
  • "It lures its prey close with hypnotic motions, then wraps its tentacles around it before finishing it off with digestive fluids."

Malamar is just a freaky Pokemon to begin with. It doesn't need any evidence in the Pokedex to back it up; just one look at its appearance, and fans will have their minds made up. However, in Pokemon Y, it is presented as a creature that lures prey with its hypnotic motions and then finishes it off with 'digestive fluids.'

Pokemon: Every Pure Steel-Type Pokemon, Ranked

There may not be many pure Steel-type Pokemon in the world, but when trained well, they can be a force to be reckoned with. But which are the best?

That last part did not need to be included; it's simply far too much information. Malamar is presented as just an evil Pokemon by itself, especially during its appearances in the anime.

43 Jigglypuff

National Dex Number: #0039

Jigglypuff In The Pokemon Anime
  • "When this Pokemon sings, it never pauses to breathe. If it is in a battle against an opponent that does not easily fall asleep, Jigglypuff cannot breathe, endangering its life."

On the face of it, Jigglypuff is a cute, little, fluffy Pokemon, but fans of the anime will know that it certainly has a mean streak, which is tied to its song. When the Balloon Pokemon sings, it lulls opponents to sleep, which is a worrying thought in itself.

But it gets even worse when it is not able to put the opponent to sleep. Its Pokemon Sapphire entry states that when it is singing, it is not breathing. So, if the enemy Pokemon doesn't fall into this trap, Jigglypuff is putting itself at risk by running out of breath.

42 Jellicent

National Dex Number: #0593

Jellicent In The Pokemon Anime
  • "The fate of the ships and crew that wander into Jellicent's habitat: all sunken, all lost, all vanished."

As a Ghost Pokemon, there is bound to be something creepy going on. Jellicent is no exception to this, and its Pokemon Black entry states that if ships wander into their habitat, they become lost and simply vanish. But where exactly do they go, and what is Jellicent doing with them?

The Pokemon franchise is chock-full of powerful Pokemon, but some feature fewer weaknesses than others.

If the Pokemon world truly existed, then it would be a terrifying place, especially for sailors if Pokemon like Jellicent could just make entire ships disappear. Most of its other Pokedex entries say that it is actively looking for fishermen to make its prey. Though this Pokemon has a very regal theme, there is clearly nothing king or queenly about this.

41 Meowstic

National Dex Number: #0678

Meowstic In The Pokemon Anime
  • "When in danger, it raises its ears and releases enough psychic power to grind a 10-ton truck into dust."

Introduced in Generation 6, the Psychic cat looks to be another cute Pokemon, but it has a particular power that results in it having one of the most horrifying Pokedex entries across the Pokemon games.

This comes in Pokemon X, and it says that it has enough psychic power to grind a 10-ton truck to dust. If it could do this to a truck, what could it do to a human? Just imagine a Pokemon trainer trying to catch a Meowstic in the wild and instead being turned 'into dust' by its psychic power. It's truly a terrifying thought.

40 Vullaby

National Dex Number: #0629

Vullaby In The Pokemon Anime
  • "It protects its plump posterior with the bones of prey it has consumed. As it grows, it replaces the bones."

The Diapered Pokemon is a Dark type, and, as a whole, this type's Pokedex entries are all unsettling. Vullaby is no exception, with its Pokemon Sun entry stating that it protects itself with the bones of the prey it consumes. Pokemon eating other Pokemon is a sad thought, but in reality, it makes sense that this could happen.

When it is time to evolve, it discards the bones, as it is now ready to fly and become a Mandibuzz. Pokemon-wearing bones of other Pokemon is not uncommon, and it even happens in the animal kingdom in the real world, too, but it's still a pretty disturbing concept. This Pokedex entry proves that Pokemon can be terrifying creatures.

39 Shedinja

National Dex Number: #00292

Shedinja In The Pokemon Anime
  • "Shedinja's hard body doesn't move - not even a twitch. In fact, its body appears to be merely a hollow shell. It is believed that this Pokemon will steal the spirit of anyone peering into its hollow body from its back."

Shedinja is a downright creepy Pokemon, even its in-game origin is disturbing. When Nincada evolves into Ninjask, if the player has a spare slot in their party and an unused Pokeball, Shedinja will appear.

Every hero in Pokemon games has a rival who challenges them throughout their journey. These are the best rivals that Pokemon trainers will ever face.

Its Pokemon Ruby Pokedex entry states that it doesn't move at all and that it will steal the spirit of anyone peering into its hollow body. This Pokemon is essentially the lifeless remains of the Nincada shell after its evolution, a reference to the husk that is left when a cicada goes through metamorphosis. Shedinja definitely has one of the creepiest origins and one of the most horrifying Pokedex entries across the Pokemon games.

38 Eevee

National Dex Number: #0133

Eevee In The Pokemon Anime
  • "Its genes are easily influenced by its surroundings. Even its face starts to look like that of its Trainer."

Most of Eevee's Pokedex entries state that its genes are unstable and that it can adapt to any environment. This is why this Pokemon can evolve into a wide range of different types using a variety of different evolution methods.

But its Pokemon Ultra Moon Pokedex entry takes this one step further. It explains that its face starts to look like that of its trainer. This highlights just how unstable Eevee's genetic makeup truly is. The fact it can change its appearance to look like its trainer is very unsettling. Just imagine an Eevee with a human face. It's a very creepy thought indeed.

37 Ninetales

National Dex Number: #0038

Ninetales In The Pokemon Anime
  • "Very smart and very vengeful. Grabbing one of its many tails could result in a 1000-year curse."

Considering Pokemon are meant to live among humans in the Pokemon world, it is quite disturbing that Ninetales can put a '1000-year curse' on someone by simply grabbing one of its tails, as explained in its Pokemon Red & Blue Pokedex entry.

Pokemon: 10 Rare Moves You've Probably Never Heard Of

There are dozens of iconic Pokemon moves, but for various reasons - though never the fault of the Pokemon themselves - these moves are rarely used.

Its Pokemon Stadium entry gives a little more background on this, stating that it will know the trainer's intention 'if its tail is pulled as a joke.' Still, the fact that it is 'very vengeful' means that it is best to not cross a Ninetales if the option ever arises. Trainers would do well to keep on the right side of this Fox Pokemon.

36 Gyarados

National Dex Number: #0130

Misty's Gyarados In The Pokemon Anime
  • "Once Gyarados goes on a rampage, its ferociously violent blood doesn't calm until it has burned everything down. There are records of this Pokemon's rampages lasting a whole month."

Gyarados is one of the best and most loved Pokemon, especially in Generation 1, where it was considered the cream of the crop among the original 151 Pokemon. A lot of its Pokedex entries explain that this Pokemon is vicious, violent, and capable of causing mass destruction.

Its Pokemon Sapphire entry takes the cake on this one: "Its ferociously violent blood doesn't calm until it has burned everything down." So, if this Pokemon is angry, it goes on a rampage and does not stop until everything is destroyed. Why do people of the Pokemon world even want to control one of these Pokemon?
