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. Sounds as different as a car crash and a symphonic passage both produce convertible incoming acoustic vibrations.
Dazzler 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. Dazzler has been shown to create a "null space" of sound in a certain radius of her person, as a result of "pulling" the sound in her area to her person, to either protect a crowd of people or to supercharge her power reserves.[31]
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.
Dazzler can produce numerous effects. She can create simple patterns out of rays of light or combinations of patterns which produce trance-like effects in her targets. She can create a pulse of light on the order of several thousand watts of power, which temporarily blinds people with its brilliance. She can create a chaotic cascade of sparkling lights and colors that severely upsets other people's equilibrium, or a pulsating strobe-light effect. Dazzler can generate a coherent beam of light, approximating a laser beam.
Dazzler has polarizing eyes and cannot be blinded or dazzled by light.[32]
With effort, she can create holograms of human beings and other three-dimensional beings and objects.
She generally directs lasers from a single finger when she requires precision. She most often uses her hands for directing her light effects, but she could also use other parts of her body. Since studying with the X-Men, she has become adept at directing her blinding strobe light blast from her eyes.
