She first appeared as a masked woman in a heavy dress. She could throw the roses that adorned her dress and use them as explosives. Her second form was quite different, and she had a handle on her hip and a gramophone on her shoulders. She could literally fling huge musical notes, or play music that was apparently very painful to those who heard it.
After her record of that music was destroyed by Tuxedo Mask, she attempted to throw her gramophone's bell at him, but realized that the last of her weapons were now gone. She was then destroyed by Sailor Moon.
