31 Days of Monsters: Day Twenty-eight — A Zombie (Voodoo)

In Vodun (voodoo) it is believed that a person could be brought back from the dead to serve a Bokor. In reality, zombies were most likely people who had been heavily drugged as a form of punishment, and were held under the Bokor's power by repeated doses of the drug, strong cultural superstition and guilt over what had made them the target of zombification in the first place.

31 Days of Monsters: Day Twenty-six — The Nucklavee

A Nucklavee was one of the most horrible goblins of Orcadian folklore. A Nuckalvee appears as a strange melding of a horse and rider, with flipper-like feet, long clawed arms, and a gigantic lolling head on it's more human half. It would haunt lonely roads and tear unwary travelers to shreds and feast on their remains. A Nucklavee could only be outrun if its intended victim could manage to cross a freshwater stream. It is believed that the smoke that resulted from burning seaweed to create soda ash could drive a Nucklavee into a murderous rampage.

31 Days of Monsters: Day Twenty-five — The Rebobs

Napa natives know all about the rebobs, hideous flying monkeys that live in the cemetery at the end of Partrick Road. Doubters will claim it's all just a story made up to keep young lovers away from a known make-out spot. But there are people who claim to have been attacked by the beasts, and lived to tell the tale. Who's really to say what's truth and what's fantasy?

31 Days of Monsters: Day Thirteen — The Jersey Devil

The Jersey, or Leeds Devil is said to haunt the Pine Barrens of Southern New Jersey.
Legend says that a woman known as Mother Leeds had been burdened with twelve awful children. Upon finding out she was pregnant a thirteenth time, she proclaimed that she wished the next child would be a devil instead of another ungrateful child. Upon being born, the cursed creature flew up the chimney and disappeared into the sky.
Now and again, people claim to see the creature. Skeptics claim the stories are either fabricated urban legends, or misidentification of native species in the area.

31 Days of Monsters: Day Ten — The Night of the Demon

The "Night of the Demon" is one of my favorite horror films. It's a great story of skepticism vs. superstition. A professional skeptic, played by Dana Andrews, travels to a conference in England where he is caught in the web of an Aleister Crowley-like magician. A piece of cursed parchment marks Andrews for death, but he remains skeptical to Carswell's power. Will he face the truth in time, and how will he save himself from ... THE DEMON!
This drawing is really a little misleading. The demon isn't really the villain in the film, it's Carswell. But the image of the demon has been a horror icon since the film came out, so I went with it instead of Carswell.
If you haven't seen the film, do yourself a favor and check it out. "Night of the Demon" was the original UK title. It was edited down to 83 minutes for U.S. release under the title "Curse of the Demon."
As a special treat, here's the trailer:
