Dazzler is a mutant with the ability to transduce sonic vibrations which reach her body into various types of light. This ability seems to operate over a great range of frequencies, including the audible spectrum, and a great variation of sound pressure levels regardless of the complexity, dissonance, or randomness of the sound. For example, a car crash and a symphonic passage of equal duration will both produce usable incoming acoustic vibrations.
Dazzler, however, prefers utilizing the sound of music, particularly that which is rhythmically sustained. Not only is music more pleasant to her ears, but the steady beat of contemporary music provides a more constant source of sound to convert. The precise means by which this conversion process works is as yet unknown. Left undirected, Dazzler's light will radiate from her body in all directions, producing regular flashes of white light. By conscious control over the light she produces, she can control its direction, frequency (color), amplitude (intensity), and duration.
