History
Little is detailed about Storm's life before Bishop arrived from the future to prevent the release of the plague, however it can be presumed that it followed as much of the same path as her Earth-92131 counterpart.
When Bishop arrived from 2055 A.D., he teamed up with the X-Men and successfully destroyed the plague, which was created by Apocalypse. However, Apocalypse then destroyed Bishop and the X-Men, including Storm.
