The creature notable for its ability to shape-shift in mythology is often the werewolf, particularly in European folklore. Werewolves are humans who can transform into wolves or wolf-like creatures, usually under the influence of the full moon. This ability symbolizes the duality of human nature, illustrating the struggle between civilization and primal instincts. Other shape-shifters include deities like Odin in Norse mythology and various trickster figures in different cultures, who embody the fluidity of identity and the changing nature of reality.
