Brandy Blumenthal serves as one of Norman Kingstadt's personal secretaries and bodyguards within Who's Who Inc. She is an elegant woman with wavy brown hair and minty blue eyes, dressed in a glamorous burgundy suit worn over a deeply cut black blouse and accessorized with black leather items featuring gold hardware. A chunky belt cinches the suit jacket at the waist, causing the hem to resemble either ruffles on a dress or the flared hem of a traditional women’s riding coat. Her suit pants are tucked into slim, calf-high riding boots reminiscent of equestrian dressage attire.

Though she maintains a calm and nearly nonchalant demeanor, she ensures that every task she begins is completed. She believes Norman would be an effective CEO if not for his preoccupation with the X-Playing cards, a habit that frustrates her yet does not diminish her respect for him. His actions often leave her dumbfounded, but her affection for him remains genuine.

She wields the 7 of Spades X-Playing card, designated "Interceptor," which grants her the ability to summon a high-performance motorcycle. This vehicle can be modified on the fly with assorted attachments including missile launchers, a sidecar, and machine guns.
