I would go with the Choctaw shadow demons:
The Choctaw have stories about
shadow beings.
Nalusa Chito, also known as a
Impa Shilup, was the soul-eater, a great black being.
[3] If individuals allowed evil thoughts or depression to enter their minds, Impa Shilup would creep inside them and eat their souls. Many people of Choctaw Nation will not say his name, in fear of summoning the spirit.
Nalusa Falaya (long black being) resembled a man, but with very small eyes and long, pointed ears. He sometimes frightened hunters or transferred his power of doing harm. Some believed that
Nalusa Falaya preferred to approach men by sliding on his stomach like a snake.
Hashok Okwa Hui'ga (Grass Water Drop) was believed to have a connection to what is termed
will-o-the-wisp. Only its heart is visible, and that only at night.
Hashok Okwa Hui'ga leads astray anyone who looks at it.
The
Kashehotapolo is a creature that is neither man nor beast. While having the legs and hoofs of a deer, its body is that of a man. His head and face are small and shriveled, and it is said that a person who looks at it will be visited by evil. When hunters go near the swamps it inhabits, it sneaks behind them to call loudly before quickly fleeing. Although it does not harm man, it takes delight in their fright as it yells a sound that resembles a woman’s scream. For that reason it was named
Kashehotapolo (
kashesho, “woman”;
tapalo, “call”).
These would make the Duke Blue Devils look like kindergarten teachers.
