A facial transformation program was employed to modify an individual's facial bone and muscle arrangement, effectively transforming their outward look to resemble someone else. Obi-Wan Kenobi made use of this program, under the direction of the Jedi High Council, to conceal his identity by adopting the guise of the bounty hunter known as Rako Hardeen. While impersonating Hardeen, Kenobi successfully disrupted Count Dooku's scheme to kidnap the Supreme Chancellor.
