Abbey Chase is a champion marksman, virtuoso of languages, scholar of world history, and (most widely) a heart-stopping femme fatale. Though spending the majority of her young life as a loner, Abbey is both a team player and a natural leader. She began her career as a freelance treasure hunter working under the radar and outside the law. And to this day, Abbey still finds herself trying to elude the many villainous characters she'd crossed and outwitted in her pre-Danger Girl days. After bumping into the Danger Girls during one of her adventure-filled hunts, Abbey shepherded the ladies to victory in their first battle against the menacing Hammer Empire. Soon after, Abbey became a full-fledged member of this international covert-operations unit. She replaced Natalia Kassle as DG's field-commander.
