This technique is a 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 this technique are reduced to faceless corpses atrocious even to look at. The user can change their voice to be like that of the victims, making a very convincing copy. Orochimaru uses this ability at various points in the series to assume different identities, particularly to make his host bodies look like his actual body.
