Someone who is a master of disguise can change their appearance, whether by use of makeup, or face mask or other means. Characters who have the ability to shapeshift are excellent at disguising themselves.
Doctor Rebos was constantly disguising himself. He disguised himself as a caterer for Eats and Drinks, and a journalist that worked for Bow-Wow Magazine. His car even had the ability to disguise itself with the push of a button.
