5 Hidebehind

A hidebehind is a nocturnal fearsome critter from American folklore that preys upon humans that wander the woods, and was credited for the disappearances of early colonial loggers when they failed to return to camp. As its name suggests, the hidebehind is noted for its ability to conceal itself. When an observer attempts to look directly at it, the creature hides again behind an object or the observer, and therefore can’t be directly seen; a feat it accomplishes by sucking in its stomach to a point where it is so slender that it can easily cover itself behind the trunk of any tree. The hidebehind uses this ability to stalk human prey without being observed, and to attack without warning. Their victims, including lumberjacks who frequent the forests, are dragged back to the creature’s lair to be devoured. The creature subsists chiefly upon the intestines of its victim. Tasty.
4 Bakeneko

Cats are meant to be furry and cute – but not when it is five feet high and shoots fireballs! A bakeneko (“monster-cat”) is, in Japanese folklore, a cat with supernatural abilities akin to those of the fox or raccoon dog. A cat may become a bakeneko in a number of ways: it may reach a certain age, be kept for a certain number of years, grow to a certain size, or be allowed to keep a long tail. A bakeneko is a cat that gains paranormal powers after certain circumstances. They also have the ability to eat (bigger or smaller) anything in its way, no matter what it is. Poison is its main food. A bakeneko will haunt any household it is kept in, creating ghostly fireballs, menacing sleepers, walking on its hind legs, changing its shape into that of a human, and
even devouring its own mistress in order to shapeshift and take her place. When it is finally killed, its body may be as much as five feet in length. It also poses a danger if allowed into a room with a fresh corpse; a cat is believed to be capable of reanimating a body by jumping over it.
3 Draugr

A draugr is an undead creature from Norse mythology. Draugar were believed to live in the graves of dead Vikings, being the body of the dead. As the graves of important men often contained a good amount of wealth, the draugr jealously guards his treasures, even after death. Draugar possess superhuman strength, can increase their size at will, and carry the unmistakable stench of decay. The draugr’s ability
to increase its size also increased its weight, and the body of the draugr was described as being extremely heavy. Thorolf of Eyrbyggja Saga was “uncorrupted, and with an ugly look about him… swollen to the size of an ox,” and his body was so heavy that it could not be raised without levers. In folklore the draugar slay their victims through various methods including crushing them with their enlarged forms, devouring their flesh, devouring them whole in their enlarged forms, indirectly killing them by driving them mad, and drinking their blood. Animals feeding near the grave of a draugr may be driven mad by the creature’s influence.
2 Monstrous Races

Pliny (in his Natural History, 77AD) gives us the first accounts of monstrous races in his attempt to describe the various unknown peoples of foreign lands. Some of the races he describes are hairy choromandae, which make a terrifying gnashing noise, half-beasts and half men created by the gods to terrify men for their amusement, and perhaps most horrifyingly a race of creatures who feed exclusively on the milk of dog-headed men (cynocephalae). In medieval history we find men with chests in their heads, and gigantic men who roam about on one leg, but prefer to lie on their back using their giant foot to protect them from the sun (sciapods). Pictured above is a weird mix of a man with a head in his chest, mixed with a bird.
1 Tiamat

We are all familiar with dragons from various historical tales and myths, but Tiamat really takes the cake for inspiring terror. Tiamat comes to us from Babylonian mythology. She is often wrongly described as being a sea-serpent or dragon, but it
is far worse than that. First, here is a description: “[Tiamat had] a tail, a thigh, “lower parts” (which shake together), a belly, an udder, ribs, a neck, a head, a skull, eyes, nostrils, a mouth, and lips. She has insides (possibly “entrails”), a heart, arteries, and blood.” She was made up of such a jumble of things that she truly was a creature of chaos. But it gets worse. Tiamat was so horrifying, so monstrous, and so dread-inspiring because, from her bizarre pseudo-human cum cryptozoological body, she gave birth to dragons,
scorpion-men, merpeople (yes, that is a real word), and countless other horrifying things. The
Tiamat myth says that she was eventually killed by the god Marduk, who then split her body in two forming heaven and earth.
