Lightforce Manipulation: After making contact with the Lightforce and learning how to channel it, Alison developed light wielding abilities. She can produce numerous effects with the light she converts from sonic vibrations. She can create very simple patterns out of rays of light like circles, squares, triangles, and stars.
Light Projection: The Lightforce within her allowed Alison to gain the ability to possesses a body-wide energy field that controls the energy levels of the outer electron shells of her body in such a way as to cause the cascaded release of photons. In effect, this field is lasing, with the apparent efficiency of a laser (99.9%). The released energy is far greater than the incoming kinetic energy and therefore must involve an outside energy source, the nature of which is 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.
Blinding Flash: Alison can create a pulse of light on the order of several thousand watts seconds of power, which temporarily blinds people with its brilliance.
Lasers: By concentrating, Alison can generate a coherent beam of light, approximating a laser beam, with which she can cut through virtually anything. The field thus operates in a similar fashion as the process that creates a laser (Light Amplification by Stimulated Emission of Radiation) and apparently has the same efficiency as a laser (99.9 percent).
Photon Blasts: Alison can generate a blast of concussive solid light.
Light Mist: Alison can create a glowing or hazy almost fog-like effect that obscures the surrounding area.
Light Immunity: Her body, especially her eyes, shields itself against any injurious effects of her light transducing abilities, and against those of bright lights in general.
Resurrection: The power of the Lightforce has given Alison the ability to resurrect herself if she is killed.
