Blonde Phantom

Introduced in All Select Comics #11 (cover-dated Fall 1946), the Blonde Phantom is the costumed identity assumed by Louise Grant, a secretary at the Mark Mason Detective Agency who secretly loves her boss. Motivated by assisting Mark Mason and solving cases he pursues, Louise removes her meek civilian trappings to become the glamorous masked heroine. The character headlined Blonde Phantom Comics (issues #12–22, Winter 1946 to March 1949) and served as a Timely Comics backup-feature through 1949. Modern Age revivals began with The Sensational She-Hulk #2 (June 1989), which reintroduced the character with metafictional awareness in later issues.

In civilian life Louise Grant is presented as a 'mousy' office secretary who wears glasses and behaves meekly. As the Blonde Phantom she becomes glamorous — letting her hair down, removing her glasses, and wearing a form-fitting evening gown often depicted with a high slit and high heels; some accounts describe the gown as floor-length. She appears wearing a domino-style mask (depictions vary) and is typically armed with a .45-caliber pistol as part of her crime-fighting equipment.

Portrayed as highly athletic and a skilled hand-to-hand combatant, the Blonde Phantom performs nightly vigilante activities to fight crime and rescue allies such as detective Mark Mason. She uses conventional firearms (notably a .45-caliber pistol) and displays agility and physical prowess consistent with Golden Age costumed heroines. In Modern Age appearances she has been written with metafictional self-awareness (including fourth-wall–aware moments) as part of later reinterpretations.
