Shapeshifting

Shapeshifting is the ability to change one's physical shape or appearance, including mimicking another species of living beings.

In the EMPATH: The Luckiest Smurf story series, the Morphs are shapeshifting spirits that inhabit blue clay and can morph into any species of living beings at all, having no specific gender as they reproduce asexually. Smurfette was originally a Morph spirit that was taken by Gargamel and made into the form of a female Smurf in order to seduce the Smurfs so that she can destroy them. Papa Smurf used his magic to transform Smurfette into a real Smurf, though years later the spell wore off and Smurfette found out her true abilities and original identity as a morph. Baby Smurf eventually changed Smurfette permanently into a real Smurf when she was abducted by the Morphs and forced against her will to stay with them, though a spirit that was trapped in her form as a real Smurf eventually emerged in the form of Smurfette's original un-Smurfy self, now called the Morphette.
