Not much is known of Sarah, not even her last name. It is possible that "Sarah" is a codename given by the Central Intelligence Agency, or it may be her actual first name.
The Central Intelligence Agency coined her as "18 years old, brown hair, skinny and tall, excellent fighting skills, familiar with weapons". In a small section of her dossier, it is also mentioned that she "co-created the ***** ******". The starred words are bolded out and are unreadable. It has been revealed that starred out words are "Sound Pistol".
