A Skin Walker, also known as a "yee naaldlooshii" (Navajo for "by means of it, he/she/it walks around on four legs") is ''usually'' a person with the supernatural ability to [[{{Shapeshifting}} change their form]] into either [[{{Animorphism}} an animal]] or [[{{Doppelganger}} another human being]].

Being very similar to [[OurWerewolvesAreDifferent Werewolves]], and other paranormal shape changers, most skin walkers' abilities are largely powered by [[BlackMagic dark ritual]], and the breaking of native taboos (Such as cannibalism, incest and murder, especially of family members) or are heralded to create them. Each tribe's version differs in details. Most Skinwalkers are differentiated from their brethren by being able to take multiple shapes, but are not free-form shapeshifters. The myths usually describe them as humans who wear only an animal skin, or an abomination of human and animal forms.

Primarily detailed in many Native American tales, these entities are sometimes portrayed as either practicing witches, or aspects of the trickster deity (Coyote) or something [[EldritchAbomination worse]], from the shared mythology of many indigenous American peoples, Skinwalkers are considered one of the most fearsome monsters from NativeAmericanMythology. In those myths, they have a few extra powers, including {{Telepathy}}, VoiceChangeling (mimicing animal and human sounds) and the creation of poisonous/disease ridden "Witch Powder" or the MagicalEye. Some cannot fully shift into their animal forms and have a [[GlamourFailure deformity]] (awkward gait, over-sized feet, etc.) revealing their true nature.

Killing one is either simplified to accusing the creature in public while in human form (which robs it of power and it dies in 3 days) or an involved, lengthy ritual.

* In the anecdotes of ''Manga/SaintSeiyaTheLostCanvas'', there are the [[OurWerebeastsAreDifferent Beast Warriors]].

[[folder: Fanfic ]]


* John Manuelito from the FanFic/AlexandraQuick series is a fairly well-researched depiction of this.

[[folder: Film ]]

* ''Film/{{Werewolf}}'' (1996) purports to be a skinwalker, instead of "the white man's {{werewolf}}." No, it's the white man's werewolf, complete with silver bullets.
** No, the thing in that film was a "yetiglanchi". [[SarcasmMode Completely different, really.]]
* Same as the film ''Skinwalker'' (2006).

[[folder: Literature ]]

* Part of the Navajo cultural background of some of Creator/TonyHillerman's Leaphorn and Chee mysteries, particularly the novel ''Literature/{{Skinwalkers}}''.
* The protagonist of the ''JaneYellowrock'' series is a skinwalker of Cherokee descent. The first book is, appropriately enough, called ''Skinwalker''.
* ''Literature/TheDresdenFiles''
** A skinwalker appears in the novel ''Literature/TurnCoat''. It mentions the classic version, the human witch, but also mentions the entities which teach them the trade: quasi-divine beings that grow more powerful the more they are feared and have an innate ability to know how to cause the maximum suffering in their victims. Gets into a CrazyAwesome ShapeshifterShowdown with [[MagicalNativeAmerican Listens-to-Wind]] (who kicks its ass in a manner most [[CrowningMomentOfAwesome righteous]]) at the end of the book. The book also presents an alternate method of killing a skinwalker, forcing it back to where it came from: [[NukeEm point-blank nuclear annihilation.]]
** The [[Series/TheDresdenFiles TV Show]] also had a Skinwalker -- which literally [[{{Squick}} stole skins]] to assume its new forms.
** ''Literature/ColdDays'' revealed that [[spoiler:there are at least six more skinwalkers currently imprisoned on the uppermost level of the supernatural jail under the Demonreach island -- and that whatever else is imprisoned below them is ''even worse'']].
** ''Literature/SkinGame'' has [[spoiler: Goodman Grey, who is part-skinwalker (apparently on his father's side). Unlike the one seen in ''Turn Coat', Grey is at least trying to be a decent person, as is shown by his helping Dresden to break into the underworld for the [[ComicallySmallDemand massive sum]] of one dollar.]]
* Mentioned, but never seen, in the ''Literature/MercyThompson'' novels. They are evil shamans who wear the skin of an animal to assume its form, and spread disease and death.
* A mutant at SuperheroSchool Whateley Academy in the ''Literature/WhateleyUniverse'' has this power, only he can move his consciousnes into an animal and take it over. He can do the same to any person he sees. He even uses the codename 'Skinwalker'. His dormmates had to devise a protocol to keep him from doing this to any of them.
* Two skinwalkers are the primary antagonists for the fourth book in the ''Literature/IronDruidChronicles''. The protagonist is tricked into dealing with them by [[PhysicalGod Coyote]], who doesn't want to risk dealing with them himself in case he fails and they get hold of his skin.
* Featured as the main antagonists in Preston and Child's ''Thunderhead''. However, [[spoiler: it ends up being a case of DoingInTheWizard as the skinwalkers gain their powers from creative use of poison and [[PsychoSerum drugs]].]]

[[folder: Live Action TV ]]

* An early episode of ''Series/TheXFiles'' called ''Shapes'' features a Native American werewolf which, during its transformation, sheds its skin in a snake-like manner. Had the episode been made today it seems likely that the monster would be called a skinwalker, but the writer instead called the beast a Manitou. This is a case of SadlyMythtaken, as a Manitou is a class of Algonquin nature spirit, while the episode treats the term as referring specifically to a lycanthrope.
* An episode of ''Series/{{Smallville}}'' has another Wolf-shifter named after these creatures, but...yeah. Not really.
* ''Series/LostTapes'' devotes an episode to it, and it is both chilling and surprisingly accurate to the legend.
* Skinwalkers are brought up in ''Series/TrueBlood'' among the "Shifters" who can change into animals they have touched. True Blood skinwalkers are shifters who have killed an immediate family member. From then on, they can take on the appearance of other people, but using this ability more than a few times is invariably fatal.
* Skinwalkers also show up on ''Series/{{Supernatural}}'' as people who can turn into various dogs and can be killed by silver.
* ''Series/{{Haven}}'' has a SerialKiller known as the Bolt Gun Killer, who has the ability to wear other people's skins after killing them and then transform into that person. The main characters suspect that the Native American legends of the Skinwalker may have been based on the Bolt Gun Killer's ancestors, as Trouble abilities are hereditary.

* [[spoiler: The Hag]] in ''VideoGame/{{Thief}}: Deadly Shadows''.
