What are some of the authentic American Indian vampire-like creatures?

Windigo: Windigos are cannibal ice giants of the Chippewa and other northern Algonquian Indian tribes. (They are also known as Chenoo in the Micmac language, Giwakwa in the Abenaki language, and a few other names in other tribes.) In most versions of the legend, Windigos were once humans who had committed cannibalism or some other terrible sin, causing their hearts to turn to ice. In other legends, people are turned into Windigos by evil wizards. Either way, the monsters are then doomed to wander the wilderness devouring every human they meet until they are killed. A few legends do have happier endings where the Windigo is able to be transformed back into a human.

Similarity to vampire legends: Used to be human, preys on humans, immortal until killed, associated with sin

Skin-Walker: Skin-walkers are fearsome shapeshifting monsters of Navajo legend. They are created when humans use forbidden evil magic and/or commit terrible crimes such as killing their own parents. Perhaps they resemble European legends of werewolves somewhat more than vampires, since skinwalkers are best known for assuming the form of animals at night to prey upon humans, then returning to human form during the daylight hours. But they also have some behaviors reminiscent of vampires, chiefly an avoidance of sunlight, immunity to normal weapons, mind-reading ability, and the ability to hypnotize and exert control over people who look them in the eyes. The best way to kill a skinwalker is to determine his secret identity, which then leaves him vulnerable to defeat during the daytime. In some stories, medicine men can also prepare sacred weapons that can be used to kill a skinwalker.

Mosquito Man: Many tribes have legends about man-eating monsters that were turned into mosquitoes, thus continuing to feed on people but in a merely annoying way rather than deadly. The Northwest Coast tribes have some particularly gruesome variants where the original monster, Mosquito Man, thrusts his proboscis into a person's head and sucks their brains out, often so surreptitiously that the people around him don't even notice their companion is dead. Here is a typical Haida version of such a legend, in which a baby is being passed around at a party and Mosquito Man stealthily sucks its brains out before passing it to the next person, who is horrified to find the child brainless and dead.

Similarity to vampire legends: Preys on humans, drains bodily fluids

Two-Face: These monsters come to us from the Sioux and other Plains tribes. They resemble humans but have a second face on the back of their heads. Making eye contact with them either strikes you dead or paralyzes you, enabling them to come back and stab you to death with their sharp elbows. The only escape is to avoid ever meeting their eyes.

Rolling Head: According to the Iroquois and other Woodland tribes, this monster is created when an unfaithful wife is killed by her husband. She returns as an undead, disembodied head, which either flies or rolls to move about. The heads usually revenge themselves on the men who killed them, but are defeated once they start terrorizing the couple's children and/or neighbors.

Similarity to vampire legends: Undead creature, used to be human, preys on humans, flies, associated with sin

Bukwus: Sometimes mistakenly identified with Sasquatch (Bigfoot), Bukwus is actually a kind of ghost of a drowned human in the folklore of the Kwakiutl and other Northwest Coast tribes. It resembles a stylized skeleton with long tangled hair and bloated facial features, and it tries to tempt humans into eating food that it offers. Any unwary traveler who partakes of its ghost food will be transformed into another undead Bukwus.

Skadegamutc: Ghost-witches of the Wabanaki tribes of New England. They are usually said to be created when an evil sorcerer dies, at which point he begins rising from the dead at night to kill and eat humans. During the day, a ghost-witch appears to be an ordinary corpse. It can only be permanently destroyed by fire.
