Shapeshifting

Folklore and mythology

The popular shapeshifting creatures in folklore include werewolves and vampires (mostly of European, Canadian, and Native American/early American origin), ichchhadhari naag (shape-shifting cobra) of India, shapeshifting fox spirits of East Asia such as the huli jing of China, the obake of Japan, the Navajo skin-walkers, and gods, goddesses and demons and demonesses such as the Norse Loki or the Greek Proteus. Shapeshifting to the form of a wolf is specifically known as lycanthropy, and creatures who undergo such change are called lycanthropes. It was also common for deities to transform mortals into animals and plants.

The prefix "were-" comes from the Old English word for "man".

While the popular idea of a shapeshifter is of a human being who turns into something else, there are numerous stories about animals that can transform themselves as well.

Greco-Roman

Examples of shapeshifting in classical literature include many examples in Ovid's Metamorphoses, Circe's transforming of Odysseus's men to pigs in Homer's The Odyssey, and Apuleius's Lucius becoming a donkey in The Golden Ass. Proteus was known among the gods for his shapeshifting; both Menelaus and Aristaeus captured him to obtain information, and they succeeded only by holding on through his many transformations. Nereus told Heracles where to find the Apples of the Hesperides for the same reason.

The Oceanid Metis, the first wife of Zeus and the mother of the goddess Athena, was believed to be able to change her appearance into anything she wanted. In one story, her pride led Zeus to trick her into transforming into a fly. He then swallowed her because he feared that he and Metis would have a son who would be more powerful than Zeus himself. Metis, however, was already pregnant. She stayed alive inside his head and built an armor for her daughter. The banging of her metalworking made Zeus have a headache, so Hephaestus clove his head with an axe. Athena sprang from her father's head, fully grown, and in battle armor.

In Greek mythology, the transformation is often a punishment from the gods to humans who crossed them.

• Zeus transformed King Lycaon and his children into wolves (hence lycanthropy) as a punishment for either killing Zeus's children or serving him the flesh of Lycaon's own murdered son Nyctimus, depending on the exact version of the myth.
• Ares assigned Alectryon to keep watch for Helios the sun god during his affair with Aphrodite, but Alectryon fell asleep, leading to their discovery and humiliation that morning. Ares turned Alectryon into a rooster, which always crows to signal the morning and the arrival of the sun.
• Demeter transformed Ascalabus into a lizard for mocking her sorrow and thirst during her search for her daughter Persephone. She also turned King Lyncus into a lynx for trying to murder her prophet Triptolemus.
• Athena transformed Arachne into a spider (hence arachnid) for challenging her as a weaver and/or weaving a tapestry that insulted the gods. She also turned Nyctimene into an owl, though in this case it was an act of mercy, as the girl wished to hide from the daylight out of shame of being raped by her father.
• Artemis transformed Actaeon into a stag for spying on her bathing, and he was later devoured by his hunting dogs.
• Galanthis was transformed into a weasel or cat after interfering in Hera's plans to hinder the birth of Heracles.
• Atalanta and Hippomenes were turned into lions after making love in a temple dedicated to Zeus or Cybele.
• Io was a priestess of Hera in Argos, a nymph who was raped by Zeus, who changed her into a heifer to escape detection.
• Hera punished young Tiresias by transforming him into a woman and, seven years later, back into a man.
• King Tereus, his wife Procne, and her sister Philomela were all turned into birds (a hoopoe, a swallow and a nightingale respectively), after Tereus raped Philomela and cut out her tongue. In revenge she and Procne served him the flesh of his murdered son Itys (who in some variants is resurrected as a goldfinch).
• Callisto was turned into a bear by either Artemis or Hera for being impregnated by Zeus.
• Selene transformed Myia into a fly when she became a rival for the love of Endymion.

While the Greek gods could use transformation punitively — such as Medusa, who turned to a monster for having sexual intercourse (raped in Ovid's version) with Poseidon in Athena's temple. Even more frequently, the tales using it are of amorous adventure. Zeus repeatedly transformed himself to approach mortals as a means of gaining access:

• Danaë as a shower of gold
• Europa as a bull
• Leda as a swan
• Ganymede, as an eagle
• Alcmene as her husband Amphitryon
• Hera as a cuckoo
• Aegina as an eagle or a flame
• Persephone as a serpent
• Io, as a cow
• Callisto as either Artemis or Apollo
• Nemesis (Goddess of retribution) transformed into a goose to escape Zeus' advances, but he turned into a swan. She later bore the egg in which Helen of Troy was found.

Vertumnus transformed himself into an old woman to gain entry to Pomona's orchard; there, he persuaded her to marry him.

In other tales, the woman appealed to other gods to protect her from rape, and was transformed (Daphne into laurel, Corone into a crow). Unlike Zeus and other gods' shapeshifting, these women were permanently metamorphosed.

In one tale, Demeter transformed herself into a mare to escape Poseidon, but Poseidon counter-transformed himself into a stallion to pursue her, and succeeded in the rape. Caenis, having been raped by Poseidon, demanded of him that she be changed to a man. He agreed, and she became Caeneus, a form he never lost, except, in some versions, upon death.

Clytie was a nymph who loved Helios, but he did not love her back. Desperate, she sat on a rock with no food or water for nine days looking at him as he crossed the skies, until she was transformed into a purple, sun-gazing flower, the heliotropium.

As a final reward from the gods for their hospitality, Baucis and Philemon were transformed, at their deaths, into a pair of trees.

Eos, the goddess of the dawn, secured immortality for her lover the Trojan prince Tithonus, but not eternal youth, so he aged without dying as he shriveled and grew more and more helpless. In the end, Eos transformed him into a cicada.

In some variants of the tale of Narcissus, he is turned into a narcissus flower.

Sometimes metamorphoses transform objects into humans. In the myths of both Jason and Cadmus, one task set to the hero was to sow dragon's teeth; on being sown, they would metamorphose into belligerent warriors, and both heroes had to throw a rock to trick them into fighting each other to survive. Deucalion and Pyrrha repopulated the world after a flood by throwing stones behind them; they were transformed into people. Cadmus is also often known to have transformed into a dragon or serpent towards the end of his life. Pygmalion fell in love with Galatea, a statue he had made. Aphrodite had pity on him and transformed the stone into a living woman.

British and Irish

Fairies, witches, and wizards were all noted for their shape-shifting ability. Not all fairies could shape-shift, some having only the appearance of shape-shifting, through their power, called "glamour", to create illusions, and some were limited to changing their size, as with the spriggans, and others to a few forms. But others, such as the Hedley Kow, could change to many forms, and both human and supernatural wizards were capable of both such changes, and inflicting them on others.

Witches could turn into hares and in that form steal milk and butter.

Many British fairy tales, such as Jack the Giant Killer and The Black Bull of Norroway, feature shapeshifting.

Celtic mythology

Pwyll was transformed by Arawn into Arawn's shape, and Arawn transformed himself into Pwyll's so that they could trade places for a year and a day.

Llwyd ap Cil Coed transformed his wife and attendants into mice to attack a crop in revenge; when his wife is captured, he turns himself into three clergymen in succession to try to pay a ransom.

Math fab Mathonwy and Gwydion transform flowers into a woman named Blodeuwedd, and when she betrays her husband Lleu Llaw Gyffes, who is transformed into an eagle, they transform her again, into an owl.

Gilfaethwy raped Goewin, Math fab Mathonwy's virgin footholder, with help from his brother Gwydion. As punishment, Math turned them into different types of animals for one year each. Gwydion was transformed into a stag, sow, and wolf, and Gilfaethwy into a hind, boar, and she-wolf. Each year, they had a child. Math turned the three young animals into boys.

Gwion, having accidentally taken the wisdom from a potion that Ceridwen was brewing for her son, fled from her through a succession of changes, which she answered with changes of her own. This ended when he turned into a grain of corn and she turned into a hen and ate him. She became pregnant, and he was reborn as a baby. He grew up to be the bard Taliesin. In the Book of Taliesin, he mentions many forms which he is able to take, including that of lantern-light.

Tales abound about the selkie, a seal that can remove its skin to make contact in human guise with people for only a short amount of time before it must return to the sea. Clan MacColdrum of Uist's foundation myths include a union between the founder of the clan and a shape-shifting selkie. Another such creature is the Scottish selkie, which needs its sealskin to regain its form. In The Great Silkie of Sule Skerry the (male) selkie seduces a human woman. Such stories surrounding these creatures are usually romantic tragedies.

Scottish mythology features shapeshifters, which allows the various creatures to trick, deceive, hunt, and kill humans. Water spirits such as the each-uisge, which inhabit lochs and waterways in Scotland, were said to appear as a horse or a young man. Other tales include kelpies who emerge from lochs and rivers in the disguise of a horse or woman to ensnare and kill weary travelers. Tam Lin, a man captured by the Queen of the Fairies is changed into all manner of beasts before being rescued. He finally turned into a burning coal and was thrown into a well, whereupon he reappeared in his human form. The motif of capturing a person by holding him through all forms of transformation is a common thread in folktales.

Perhaps the best-known Irish myth is that of Aoife who turned her stepchildren, the Children of Lir, into swans to be rid of them. Likewise, in the Tochmarc Étaíne, Fuamnach jealously turns Étaín into a butterfly. The most dramatic example of shapeshifting in Irish myth is that of Tuan mac Cairill, the only survivor of Partholón's settlement of Ireland. In his centuries-long life, he became successively a stag, a wild boar, a hawk, and finally a salmon before being eaten and (as in the Wooing of Étaín) reborn as a human.

The Púca is a Celtic faery, and also a deft shapeshifter. He can transform into many different, terrifying forms.

Sadhbh, the wife of the famous hero Fionn mac Cumhaill, was changed into a deer by the druid Fer Doirich when she spurned his amorous interests.

Norse and Teutonic

There is a significant amount of literature about shapeshifters that appear in a variety of Norse tales.

In the Lokasenna, Odin and Loki taunt each other with having taken the form of females and nursing offspring to which they had given birth. A 13th-century Edda relates Loki taking the form of a mare to bear Odin's steed Sleipnir which was the fastest horse ever to exist, and also the form of a she-wolf to bear Fenrir.

Svipdagr angered Odin, who turned him into a dragon. Despite his monstrous appearance, his lover, the goddess Freyja, refused to leave his side. When the warrior Hadding found and slew Svipdagr, Freyja cursed him to be tormented by a tempest and shunned like the plague wherever he went. In the Hyndluljóð, Freyja transformed her protégé Óttar into a boar to conceal him. She also possessed a cloak of falcon feathers that allowed her to transform into a falcon, which Loki borrowed on occasion.

The Volsunga saga contains many shapeshifting characters. Siggeir's mother changed into a wolf to help torture his defeated brothers-in-law with slow and ignominious deaths. When one, Sigmund, survived, he and his nephew and son Sinfjötli killed men wearing wolfskins; when they donned the skins themselves, they were cursed to become werewolves.

The dwarf Andvari is described as being able to magically turn into a pike. Alberich, his counterpart in Richard Wagner's Der Ring des Nibelungen, using the Tarnhelm, takes on many forms, including a giant serpent and a toad, in a failed attempt to impress or intimidate Loki and Odin/Wotan.

Fafnir was originally a dwarf, a giant, or even a human, depending on the exact myth, but in all variants, he transformed into a dragon—a symbol of greed—while guarding his ill-gotten hoard. His brother, Ótr, enjoyed spending time as an otter, which led to his accidental slaying by Loki.

In Scandinavia, there existed, for example, the famous race of she-werewolves known by the name of Maras, women who took on the appearance of huge half-human and half-wolf monsters that stalked the night in search of human or animal prey. If a woman gives birth at midnight and stretches the membrane that envelopes the child when it is brought forth, between four sticks and creeps through it, naked, she will bear children without pain; but all the boys will be shamans, and all the girls Maras.

The Nisse is sometimes said to be a shapeshifter. This trait also is attributed to Hulder.

Gunnhild, Mother of Kings (Gunnhild konungamóðir) (c. 910 – c. 980), a quasi-historical figure who appears in the Icelandic Sagas, according to which she was the wife of Eric Bloodaxe, was credited with magic powers – including the power of shapeshifting and turning at will into a bird. She is the central character of the novel Mother of Kings by Poul Anderson, which considerably elaborates on her shapeshifting abilities.

In the Finnish epic poem Kalevala of ancient folklore, Louhi, Mistress of the North, attacks Väinämöinen in the form of a giant eagle with her troops on her back as he tries to steal Sampo.

Indian

• Ichchhadhari naag: A common male cobra will become an ichchhadhari naag and a common female cobra will become an ichchhadhari naagin after 100 years of tapasya (penance). After being blessed by Lord Shiva, they attain a human form of their own and have the ability to shapeshift into any living creature, they can live for more than a hundred years without getting old.
• Yoginis were associated with the power of shapeshifting into female animals.
• In the Indian fable The Dog Bride from Folklore of the Santal Parganas by Cecil Henry Bompas, a buffalo herder falls in love with a dog that has the power to turn into a woman when she bathes.
• In Kerala, there was a legend about the Odiyan clan, who in Kerala folklore are men believed to possess shapeshifting abilities and can assume animal forms. Odiyans are said to have inhabited the Malabar region of Kerala before the widespread use of electricity.

Armenian

In Armenian mythology, shapeshifters include the Nhang, a serpentine river monster that can transform itself into a woman or seal, and will drown humans and then drink their blood; or the beneficial Shahapet, a guardian spirit that can appear either as a man or a snake.

Philippines

Philippine mythology includes the Aswang, a vampiric monster capable of transforming into a bat, a large black dog, a black cat, a black boar, or some other form to stalk humans at night. The folklore also mentions other beings such as the Kapre, the Tikbalang, and the Engkanto, which change their appearances to woo beautiful maidens. Also, talismans (called "anting-anting" or "birtud" in the local dialect), can give their owners the ability to shapeshift. In one tale, Chonguita the Monkey Wife, a woman is turned into a monkey, only becoming human again if she can marry a handsome man.

Tatar

Tatar folklore includes Yuxa, a hundred-year-old snake that can transform itself into a beautiful young woman, and seeks to marry men to have children.

Chinese

Chinese mythology contains many tales of animal shapeshifters, capable of taking on human form. The most common such shapeshifter is the huli jing, a fox spirit that usually appears as a beautiful young woman; most are dangerous, but some feature as the heroines of love stories. Madame White Snake is one such legend; a snake falls in love with a man, and the story recounts the trials she and her husband faced.

Japanese

In Japanese folklore obake are a type of yōkai with the ability to shapeshifting. The fox, or kitsune is among the most commonly known, but other such creatures include the bakeneko, the mujina, and the tanuki.

Korean

Korean mythology also contains a fox with the ability to shapeshift. Unlike its Chinese and Japanese counterparts, the kumiho is typically always malevolent. Usually its form is of a beautiful young woman; one tale recounts a man, a would-be seducer, revealed as a kumiho. The kumiho has nine tails and as she desires to be a full human, she uses her beauty to seduce men and eat their hearts (or in some cases livers where the belief is that 100 livers would turn her into a real human).

Somali

In Somali mythology Qori ismaris ("One who rubs himself with a stick") was a man who could transform himself into a "Hyena-man" by rubbing himself with a magic stick at nightfall and by repeating this process could return to his human state before dawn.

Southern Africa

ǀKaggen is a demiurge and folk hero of the ǀXam people of southern Africa. He is a trickster god who can shape shift, usually taking the form of a praying mantis but also a bull eland, a louse, a snake, and a caterpillar.

Indigenous American

A Pukwudgie is a human-like creature from Wampanoag folklore said to appear and disappear at will, and shapeshift.

South American

Amazon river dolphins, known by the natives as the boto, encantados or toninhas, are very prevalent in the mythology of the native South Americans. They are frequently characterized in mythology with superior musical ability, seductiveness and love of sex, resulting in illegitimate children, and attraction to parties. Despite the fact that the Encante are said to come from a utopia full of wealth which is also without pain or death, they crave the pleasures and hardships of human societies.

Transformation into human form is said to be rare, and usually occurs at night. The encantado will often be seen running from a festa, despite protests from the others for it to stay, and can be seen by pursuers as it hurries to the river and reverts to dolphin form. When it is under human form, it wears a hat to hide its blowhole, which does not disappear with the shapeshift.

Besides the ability to shapeshift into human form, encantados frequently wield other magical abilities, such as controlling storms, hypnotizing humans into doing their will, transforming humans into encantados, and inflicting illness, insanity, and even death. Shamans often intervene in these situations.

Along with shapeshifting, kidnapping is also a common theme in such folklore. Encantados are said to be fond of abducting humans with whom they fall in love, children born of their illicit love affairs, or just about anyone near the river who can keep them company, and taking them back to the Encante. The fear of this is so great among people who live near the Amazon River that both children and adults are terrified of going near the water between dusk and dawn, or entering water alone. Some who supposedly have encountered encantados while out in their canoes have been said to have gone insane, but the creatures seem to have done little more than follow their boats and nudge them from time to time. The myth is suggested to have arisen in part because dolphin genitalia bear a resemblance to those of humans. Others believe the myth served (and still serves) as a way of hiding the incestuous relations which are quite common in some small, isolated communities along the river. Legend also states that "if a person makes eye contact with an Amazon river dolphin, they will have lifelong nightmares".

Trinidad and Tobago

The Ligahoo or loup-garou is the shapeshifter of Trinidad and Tobago's folklore. This unique ability is believed to be handed down in some old creole families, and is usually associated with witch-doctors and practitioners of African magic.

Mapuche (Argentina and Chile)

The name of the Nahuel Huapi Lake in Argentina derives from the toponym of its major island in Mapudungun (Mapuche language): "Island of the Jaguar (or Puma)", from nahuel, "puma (or jaguar)", and huapí, "island". There is, however, more to the word "Nahuel" – it can also signify "a man who by sorcery has been transformed into a puma" (or jaguar).

Slavic mythology

In Slavic mythology, one of the main gods Veles was a shapeshifting god of animals, magic and the underworld. He was often represented as a bear, wolf, snake or owl. He also became a dragon while fighting Perun, the Slavic storm god.
