In Greek mythology, the transformation is often a punishment from the gods to humans who crossed them. The Children of Lir, transformed into swans in Irish tales Athena sprang from her father's head, fully grown, and in battle armor. The banging of her metalworking made Zeus have a headache, so Hephaestus clove his head with an axe. She stayed alive inside his head and built armor for her daughter.

He then swallowed her because he feared that he and Metis would have a son who would be more powerful than Zeus himself. In one story, she was so proud, that her husband, Zeus, tricked her into changing into a fly.

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. Nereus told Heracles where to find the Apples of the Hesperides for the same reason. Proteus was noted among the gods for his shape-shifting both Menelaus and Aristaeus seized him to win information from him, and succeeded only because they held on during his various changes.

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. The prefix "were-", coming from the Old English word for "man" (masculine rather than generic), is also used to designate shapeshifters despite its root, it is used to indicate female shapeshifters as well. Other terms for shapeshifters include metamorph, the Navajo skin-walker, mimic, and therianthrope.

It was also common for deities to transform mortals into animals and plants. Therianthropy is the more general term for human-animal shifts, but it is rarely used in that capacity. Shape-shifting to the form of a gray wolf is specifically known as lycanthropy, and such creatures who undergo such change are called lycanthropes. Popular shape-shifting creatures in folklore are werewolves and vampires (mostly of European, Canadian, and Native American/early American origin), ichchadhari naag and ichchadhari naagin (shape-shifting cobras) of India, the huli jing of East Asia (including the Japanese kitsune and Korean kumiho), and the gods, goddesses, and demons and demonesses like succubus and incubus and other numerous mythologies, such as the Norse Loki or the Greek Proteus. 1722 German woodcut of a werewolf transforming
