The Irish (Original Sleepy Hollow).

Usually, the Dullahan is male, but there are some female versions.
The mouth is usually in a hideous grin that touches both sides of the head.
Its eyes are constantly moving about and can see across the countryside even during the darkest nights.
The flesh of the head is said to have the color and consistency of moldy cheese.
When the Dullahan stops riding, that is where a person is due to die.
The Dullahan calls out the persons name, at which point the person immediately perishes.
They are frightened of gold, and even a single gold pin can drive a Dullahan away.

The Wendigo
I like the Wendigo a lot.
There are a handful of different versions, but theyre all cool.
First is the spirit of cannibalism.
The definitive non-Native depiction of the Wendigo is from Algernon BlackwoodsThe Wendigo, which is a great story.

Each Uisge
Without question, the Each Uisge (pronounced something like ak ishka).
It can shapeshift into other things, but the Scottish Murderhorse aspect is easily the most metal.

Pesta was an old woman dressed in black, carrying with her a broom and a rake.
She travelled from village to village, bringing pestulance and death with her.
If you was carried the broom, she would take the lives of everyone at the farm.
There was a ferryman out in his boat one evening.
On his way across the water he could hear someone call out for him.
He looked towards the harbor and there he could see a old woman.
The ferryman called out with a trembling voice.
I will bring you across if you spare my life!
The old crone slightly tilted her head and reached for the big black book she hid within her clothing.
With a bony finger she read the names written within, her thin and pale lips muttering to herself.
She lifted her eyes towards the ferryman.
The old crone stepped on board the boat and seated herself in the prow.
When the ferryman came home later that evening, he felt very tired.
So he laid himself down in bed, and never woke up.

These days we use the word doppelgangerto reference someones non-related twin.
Someone who naturally looks exactly like someone else without any blood relation.
Its a rare coincidence, but thats not the words original definition.
It was said that the doppelganger consumed the original person once the transformation was complete.
This was used to explain early misunderstood cases of Alzheimers.

The Pukwudgie
The Pukwudgie.
An American criptid with a mythological history.
Its said to exist in the forests starting in the east coast mountains and all through to Kentucky.
Several Native American tribes describe these creatures.
They resemble small men, around a foot tall with gaunt features.
There most prominent attributes would have to be there unusually large noses and shaggy long moss colored hair.
Now they hate people with a passion.

And to be specific, slow zombies.
They endlessly creep towards you to eat your brains.
Sure, they are slow.
You board up your doors and windows, but their dead hands reach through any gap.
They keep pushing and trying.
All the while their desperate moans fill your ears driving your mind with fear to the brink of madness.
Yes, hell has been filled due to the evil of man and the dead now walk the earth.

Cthulhu
Its great and 99% of people who know about Cthulhu know the wrong thing about it.
They think its a bigmonster, that you could fight it, you could tame it, whatever.
It represents something so powerful that you just cant comprehend it, trying to understand it drives you mad.
We would just be these weird undulating shapes popping into and out of existence.
