Shapeshifting, transformation or transmogrification refers to a change in the form or shape of a person. It primarily refers to:

• a change from human form to animal form and vice versa
• a change in appearance from one person to another

Although shapeshifting is not believed to be scientifically or medically possible, it is a common theme in myth and legend and a popular theme in science fiction and fantasy stories.

"Shapeshifting" often refers to characters who change form on their own, whether voluntarily or involuntarily, while "transformation" refers more commonly to externally imposed change of form, whether by magic or sufficiently advanced technology. However, there is no settled agreement on the terminology.

Shapeshifting in myth

Popular shapeshifting creatures in myths and legends are werewolves and vampires (mostly of European, Canadian, and Native American/early American origin), the kitsune or were-foxes of Japan, and the gods and goddesses of numerous mythologies, such as Loki from Norse mythology or Proteus from Greek mythology. It was also common for deities to transform humans into animals and plants.

Although shapeshifting to the form of a wolf is specifically known as lycanthropy, and such creatures who undergo such change are called lycanthropes, those terms have also been used to describe any human-animal transformations and the creatures who undergo them. Therianthropy is the more general term for human-animal shifts, but it is rarely used in that capacity.

Other terms for shapeshifters include metamorph, skin-walker, mimic, therianthrope, and were.

Almost every culture around the world has some type of shapeshifting myth, and almost every commonly found animal (and some not-so-common ones) probably have a shapeshifting myth attached to them. Usually, the animal invovled in the transformation is most likely indigenous to or prevalent in the area from which the story derives.

Also, it is worthy to note that while the popular idea of a shapeshifter is of a human who turns into something else, there are numerous myths about animals that can transform themselves as well.

Examples of shapeshifting in classical literature include many examples in Ovid's Metamorphoses, Circe's transforming of Odysseus' men to pigs in Homer's The Odyssey, and Apuleius's becoming a donkey in The Golden Ass.

Notable mythological shapeshifters

• werewolves -- humans who turn into wolves
• vampires -- corpses who can turn into wolves and/or bats
• Bouda -- hyena-men of Africa

Shapeshifting in fiction

Shapeshifters appear in many fantasy and science fiction stories.

The word "transmogrification" has been popularized by the transmogrifier used in Calvin and Hobbes.

• Many of Jack L. Chalker's novels involve one or more transformations; he wrote an essay on physical transformation as a metaphor for various psychological changes, included in his short story collection Dance Band on the Titanic. This theme is used several times in the Jerry Cornelius stories by Michael Moorcock, as well as in works by Robert Sheckley, Nina Kiriki Hoffman and others.
