Monica Rambeau form of energy within the electromagnetic spectrum. Among the many energy forms she has assumed and is able to control are cosmic rays, gamma rays, X-rays, ultraviolet radiation, visible light, electricity, infrared radiation, microwaves, radio waves, and neutrinos. By assuming an energy-form, she gains all of that energy's properties. She is invisible and intangible in many of her energy forms (the most frequent exception being visible light), and is capable of flight in all her energy forms (reaching velocities up to and including light speed). She also has the ability to project these energies from her body while she is
