Metamorphosis

Metamorphosis was a form of shapeshifting based not on species biology, but the Force. Through primitive magic or Force-imbued artifacts, a being could change its shape into that of another person, creature, or entity through the use of the Force.

Apart from the masquerade technique, metamorphosis was uncommon among Force-using traditions like the Jedi and the Sith, but not among the mysterious witches known as the Nightsisters of Dathomir, who utilized Talismans of Transformation and traditional Dathomiri illusions to metamorphose.
