Storm (also known as Ororo Munroe) is a powerful mutant with the ability to control the weather; temperature of the environment, can generate all forms of precipitation, generate lightning and other electromagnetic atmospheric phenomena, and has demonstrated excellent control over atmospheric pressure. She can incite all forms of meteorological tempests, such as tornadoes, thunderstorms, blizzards, and hurricanes, as well as mist. She can dissipate such weather to form clear skies as well. She has finite control, down to the molecule, that she she can levitate by manipulating the air surrounding her body.
Angela Bassett and Janet Jackson were first approached to portray Storm in late 1997.
