The Keymaster appears like a normal human, pale grey skin and teal-colored eyes. He has long, unkempt wiry black hair, and a light amount of facial hair. His figure is tall yet slim (standing at 6'10 feet), and he wears form-fitting attire, enclosed within an old-fashioned black leather trench coat. The trademark of his appearance is a large ring of distinctive Level Keys attached to his right hip. A dark mist of indeterminate properties proceeds his movements at waist-height.
