30 Evil & Dangerous Mythical Creatures

Have you ever wondered what the most evil mythical creature is? The answer may surprise you.

There are many mythological creatures that are considered to be evil, but only one can be deemed as the most evil of them all.

Whether they live in a forest or deep underwater, there’s no denying that these monsters have been wreaking havoc for centuries and will continue to do so until we find out how to defeat them!

Top 30 Evil and Dangerous Mythical Creature List:

1. Cyclops

The word ‘cyclops’ is nowadays being used to describe any frightening creature with only one big eye, but the original cyclopses were called Arges, Steropes, and Brontes. It is debatable whether the originals could be considered dangerous, but the more modern versions certainly tend to be.

2. The Kraken

In the sea off the coast of Norway and Greenland, that’s where the Kraken lives. The myth dates back to a time when sailors were terrified to end up in the monster’s unforgiving grip, and the Kraken supposedly pulled whole fleets of ships down into the deepest waters.

3. Cerberus

Have you ever seen a three-headed dog in a movie or read about one in a book? The original name for this beast is ‘Cerberus’, and in most stories, it is a mythical (and monstrous) creature that guards treasures and more.

4. Dragons

Whenever you read about a dragon in storybooks and old tales, you can almost feel the horror of watching that massive animal come flying over the mountain tops – knowing it has the capacity to burn down villages and towns.

5. Goblins

Described as small, ugly, and malicious, Goblins are trouble-makers that bring little to nothing good with them, and they originate from old European folklore and myths. Goblins are considered selfish and greedy – always putting themselves first.

6. The Gorgons

The three gorgons in Greek mythology are Medusa, Stheno, and Euryale, with Medusa being the most famous (and potentially the most dangerous) gorgon. All three have snakes instead of hair, and they were all turned into gorgons after Medusa had a love affair with Poseidon.

7. Chimeras

There are many scary stories told of the chimeras. In real life, a chimera is a human or an animal with two sets of DNA, but in mythology – it is a vicious beast composed of parts from various different animals. Chimeras often have a lion’s body.

8. Dybbuk

When someone dies in Jewish mythology, there are supposedly cases where the soul of the deceased could get lost, and this is when a Dybbuk may decide to possess the body. Some believe firmly in the existence of these and it is not unusual to use exorcism to try and drive them out.

9. Bigfoot/Sasquatch

While this phenomenon and the mythical creature is best known in Canada and the United States. Many have heard the name briefly mentioned in movies or literature. Bigfoot is believed to be a massive ape-man living in the woods, and it is common knowledge that you don’t want to cross paths with him when you are out in nature.

10. Aqrabuamelu

Many mythical creatures have things in common, and this hybrid may remind you of a few others! In this case, the top half of the Aqrabuamelu is a man and the other half is a scorpion. Most stories describe him as extremely tall and dangerous.

11. Basilisks 

These giant snakes shouldn’t be forgotten when discussing the most dangerous mythical creatures out there, as all it takes for it to kill you is one single look. “If looks could kill” certainly fits this beast.

12. Medusa

While we have already covered the Gorgons, the worst and most dangerous of the three deserves its own spot. Medusa appears not only in old Greek mythology but in countless modern stories and tales. Crossing paths with her almost always meant certain death.

13. Golems

In Jewish folklore, Golems are creatures that can be summoned using certain Hebrew letters in a specific order, or through complex rituals. Once summoned, golems form from sand, rocks, and other objects.

14. Oni

The man-eating Oni is a Japanese mythical creature known for its terrifying appearance – often portrayed as a hunched over goblin-like monster with a horn and long fingers.

15. Pontianak

The Pontianaks are evil spirits that lure their prey by shapeshifting into stunning women. In the stories, they are sometimes explained as the lost souls of those women who never had children of their own.

16. Kappas

Have you ever heard about a polite and proper monster that is also evil and extremely dangerous? Kappas are just that. Reptile-type monsters with certain human features, that present immediate danger to both animals and humans alike.

17. The Sphinx

This is one of those monsters that are described as quite pleasant to look at, but if you failed to answer the impossible riddle of the Sphinx – it would viciously attack and kill without its victims standing a chance.

18. Centaurs

While centaurs are generally not considered evil, they are impulsive, unpredictable and as a result – unreliable. Half their body is human and the other part (usually the lower part of the body) is a horse, and you never really know what you are going to get with these wine-loving mythical creatures. 

19. Harpies

As if being sent down to Hades’ domain wasn’t bad enough, travelers also had to watch out for harpies – a creature with the body of a bird and the face of a human. These calculated hybrids would snatch any human they could get their claws on, and subject the individual to excruciating torture.

20. The Furies

The three furies only presented a danger to those who had committed some type of sin – men, in particular, as these creatures were the goddesses of vengeance. Any man who committed a wrongdoing, such as murder or an unforgivable crime against the gods, would fear the vengeance of the furies.

21. Echidna 

The wife of Typhon and a hybrid creature with a woman’s face and the body of a snake. Argus Panoptes was the one to eventually slay Echidna in her sleep.

22. Hydra

Hydra, or the Lernaean Hydra, was an almost impossible monster to kill. This water creature had many heads that would attack its victim simultaneously, and while some tried to chop the heads off one by one – they quickly discovered that when one of Hydra’s heads were cut off, two more would grow out in its place.

23. Typhon

The husband of Echidna and the father of many of the monsters found in Greek mythology. Like his wife, Typhon was also a snake-like creature and described as having 100 heads which would each breathe fire.

24. Banshees

Banshees appear in Irish folklore and is not necessarily evil or dangerous, but she is strongly connected to the death of someone in the family, and therefore considered both a bad omen and an unwanted visitor.

25. Charybdis

You can’t learn about Charybdis without learning about Scrylla, as the two are connected. Charybdis was believed to be a terrifying sea monster that would create whirlwinds out at sea and pull anyone (and anything into it), and he was considered worse than Scrylla, who lived on the other end of the same sea.

26. Lamia

Lamia turned into a monster after losing her children due to unfortunate circumstances, and she became an evil creature that would hunt down the children of others and kill them viciously.

27. The Aqrabuamelu

In Mesopotamian mythology, the aqrabuamelu is a terrifying creature that is half scorpion and half man. This type of hybrid is also found in other mythologies, but these were also claimed to be so tall they could reach the sky.

28. The Loch Ness Monster

The Loch Ness Monster can be described as a prehistoric type beast that lurks under the surface of lake Loch Ness. It is a long-lived myth and a monster that has never been proven to exist, even though it has been continuously spotted throughout the years.

29. Sirens

Sirens are sometimes described as a type of mermaid, but in Greek mythology, they were half-bird and half-women, and they would sing an enchanting song to lure sailors to their inevitable death and destruction.

30. The Nixie

There are many different versions of this Scandinavian mythical creature, but one is described as a naked man who presented a deadly threat to women and children. He would sit and play his violin in streams, lakes, and rivers, and the sound would bring his victims to walk into the water and drown.
