Valerie Vaughn was a pampered rich girl who wanted to do more, and she did by seeking out danger and adventure wherever she could find it, jumping into deep-sea diving, solo aviation, and daredevil stunts. During this she also ran into a number of villains whom she took down.
Soon she became known as Lady Danger, eventually, because of a challenge from her father, she decided to do more than just look for danger, instead she became a newspaper reporter and sought danger while also looking for a story.
