The X-Men member with the power to control the weather is Storm, whose real name is Ororo Munroe.
Storm is one of Marvel's most powerful mutants. She can manipulate atmospheric conditions, including wind, rain, lightning, temperature, humidity, and pressure. Her abilities allow her to summon storms, create powerful gusts, fly by riding air currents, and sometimes influence weather across a very large area. Her power is often connected to her emotional state, so discipline and concentration are essential.
Ororo was born in New York City and raised partly in Cairo, Egypt, before becoming a thief and later joining the X-Men. Professor Charles Xavier recruited her because of her remarkable abilities and potential. She eventually became one of the team's most respected field leaders, taking command during periods when Cyclops or Professor X was unavailable.
Readers sometimes confuse Storm's weather control with Jean Grey's telekinesis or Rogue's ability to absorb powers. Emma Frost is also an exceptionally powerful mutant, but her signature abilities are telepathy and transforming her body into diamond form. Storm's distinctive domain is the atmosphere itself.
