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
Invisible ink its intended use. For example, property marking should ideally be done with ink easily read under ultraviolet light, whereas in espionage such an ink would be considered too easily detectable since a large number of letters may be screened relatively quickly using UV light. Invisible inks are inherently "insecure" against a determined and well-equipped inspector, which must be balanced against the logistical difficulty in carrying out mass-screening of posted mail. It is easier to perform large-scale undetected screening of millions of electronic communications, than to mass-screen even a small fraction of conventional mail. Apart from in dictatorships where large numbers
