PSI can make anyone she looks at experience their greatest fear or relive the most terrifying, traumatizing moment in their lives. This creates illusions within her victims, which will incapacitate them until the effects wear off. She is a sociopathic criminal, with her main motivation being money. She seems to have childlike glee in using her powers, taking sadistic pleasure in making the people around her submit to their worst fears, treating it like a "fun" game.
