Vanishing Facial Copy Technique

This technique was developed for spying with grisly effects. The user applies their hand onto the subject's face, stealing its features and making it their own. Since what is stolen is the face itself, the disguise achieved through facial features alteration won't reveal the tiniest flaw. The victims of this technique are reduced to faceless corpses. The user can even change their voice to sound like that of the victims, making a very convincing copy. However, with enough force, the face can wrinkle and tear to the point of the user's actual face being shown underneath. The face can be peeled off at any point.
