Illusion of Face

Illusion of Face, also loosely known as Force shapeshift, was a dark side Force power that allowed a user to modify facial features such as scars, wrinkles, and eye color. Darth Plagueis and his apprentice Darth Sidious were the best known masters of this power. The Jedi Order forbade knowledge of the power after a rogue Padawan in c. 500 BBY used Illusion of Face to conceal his identity in a string of robberies and cold-blooded murders across Coruscant before finally being tracked and killed by another Padawan.
