She was a spoiled child, more so then most as her parents were wealthy and there was nothing that she wanted that they could not buy. This would normally lead to physiological problems as the child grows up and learn that life in not like that. Her case was something else entirely.
If not for her upbringing, she may have become would of the most powerful superhero's ever, but as it is, when her powers manifested, her mind used them to again get everything that she wants.
She has the ability to create almost anything that she wants, however her power is controlled by her subconscious. What she wants right now is to meet her "knight in shining armor" or in today's language a superhero that will be her boyfriend. To do this her subconscious makes various things that would make a hero show up and save her. She is not a fighter by any stretch of the imagination, in encounter with Princess always has her in need of rescue from the grip of a horrifying monster.
Example: Woman attacked by giant fire breathing dragon. Once she feels that the dragon has had enough, it vanishes and she is left alone with the superhero, she may even faint and need a kiss to wake her up. Sometimes more then one monster is necessary to test the strength of the heroes love of Princess.
