Medusa, a Greek gorgon, is known for one pretty distinctive feature: instead of a head full of hair, she has snakes. The snakes aren't what you need to worry about, though, because if you happen to catch so much as a glimpse of Medusa's face, you'll turn to stone.

   Midgarðsormr
2. Scylla
   Nessie

Named for Loch Ness, its home, Nessie is a long-necked, aquatic monster that many cryptozoologists believe to be a plesiosaur. Although Nessie rose to fame in the '30s when the image above was faked, records of its supposed existence go as far back as the year 565 AD.

1. Unicorn

   Tiamat
2. Troll
   Capricorn

If the ceasg looks familiar, there's a reason -- you probably know it as a mermaid. Although it goes by a different name, being Scottish, the ceasg is functionally the same; it's half-human, half-fish (specifically, salmon), and anyone who captures it will receive three wishes.

Sirens are the ultimate femme fatale. A Greek monster, sirens use their voices and alluring looks to trick sailors into wrecking their ships on the rocky islands the sirens call home. The number of sirens in existence varies from author to author, but there's usually only a handful around at a time, meaning you're likely safe if you want to venture into Mediterranean waters today. Just don't pay heed to any melodies you may hear while on the waves.

1. Griffin
   Basilisk
2. Dragon
   Wyvern

Capable of killing a person with a single glance, the basilisk is no small threat. Despite this, the legendary reptile has one peculiar weakness - the scent of a weasel, which can kill the basilisk on its own, although the weasel will also die in the process. Mythology experts suspect that the weasel being the basilisk's weakness may have something to do with European snakes and the fact that weasels are often their natural predators.

1. Chupacabra
   Jackalope
2. Jersey Devil

1. Zombie
   Nosferatu
2. Jiangshi
   Draugr

The zombie as we know it is pretty recent compared to other legends of the undead. These shambling monsters are the dead reanimated, and they survive on human flesh - most famously, brains. Their origins are traced to Haitian folklore, which involved magic; something modern western iterations tend to skip.

1. Mummy
   Sasquatch
2. Yeti
   King Kong

The Nepalese Yeti, also known as the Abominable Snowman, is usually thought of as Bigfoot's chilly cousin - and it's easy to see why, with all that pristine white fur. Folklore states that the Yeti lives in the Himalayans across Nepal, Bhutan, ​and Tibet, but Americans have also adopted the beast.

1. Fairy
   Orc
2. Dwarf
   Redcap

The orcs you're familiar with may have taken inspiration from ancient mythology, J.R.R.

   Oni
2. Kitsune
   Ogre

1. Mothra
   Chinese dragon

1. Incubus
   Baphomet
2. Succubus
   Azazel

The sexy succubus is one lady whose sheets you don't want to find yourself tangled up in. While they may appear to be beautiful, succubi are actually demons who want to steal the souls of men, and they usually get what they want through sex. If you take a second look, though, you might notice something off about a succubi's human form; for example, she may have claws ​or even a tail. Steer clear if that's the case.

1. Incubus

1. Changelings
   Spriggan
2. Red Hats
   Loki

Folklore describes the changeling as a creature that has been left in the place of a human child, which has been stolen by fairies.

1. The Bell Witch
   Circe
2. Loogaroo
   Baphomet

A large statue of the beast now sits in front of the Rhinelander Chamber of Commerce.

   Skunk Ape
2. Mothman

If they're caught by humans, they sometimes grant three wishes.

1. Tsuchigumo
   Mothman
2. Kuluwajak
   Mothra

As a more recent monster, the Mothman can be traced back to November 16, 1966, when the Point Pleasant Register published a story about its first sighting. Later novelizations and films, including John Keel's "The Mothman Prophecies," further popularized the creature, which is sometimes confused for a large bird with red eyes, the Mothman's second best-known​ feature.

1. Jötnar
   Grendel
2. Ogre
   Bluebeard

An ogre, or ogress if female, is an uncouth monster seen widely across western mythology and folklore. Most often, it is larger than the average human - bulky, misshapen, with discolored skin. They also have a habit of munching on humans, so steer clear -- Dreamworks Pictures' "Shrek" was one of the nice ones.

1. Shapeshifters
   Werewolf
2. Nypmh

1. Qiqirn
   Ghast
2. Skinwalkers
   Swamp-Woman

The Navajo people have a scary creature of their own: skinwalkers. Skinwalkers are witches who can either transform into animals or disguise themselves as such, and they always come bearing ill will unto those unfortunate enough to see them. The Navajo are notoriously tight-lipped about skinwalkers, and so information about them is scarce among outsiders.

1. Lusca
   Moby Dick
2. Leviathan

Children are especially vulnerable to its wiles.
