Betty Babble -- no, seriously, Betty Babble -- is a stuntwoman turned movie star. When her leading man (and informant) is killed mid-scene, she sets out to find the killer.
Certain story elements suggest this is not her first adventure, although it's the only one ever published. She has fighting skills, probably from her time as a stuntwoman, and the crime-busting mentality of a young Jessica Fletcher.
Perhaps any future stories might have shown her in different attire. But we'll never know. Unlike Ghost Woman, poor Commandette doesn't even inspire a knock off.
