Origin
Kitty Kelly was a woman who discovered that she had remarkably strong adrenal glands so that whenever she became angry or excited she gained fantastic strength and endurance. Deciding to put this to use to fight crime and/or evil she designed a costume, but could not come up with a name so just put the initials of her name on her costume and let the criminals figure out who she was, their usual response to her bursting through the door of one of their hideouts was “who’s this dame?” just before she picked one of them up and used him to clean the floor with the rest of them.
Not to be confused with another character at another company who was a stewardess also called Kitty Kelly.
