History
Ms. Marvel's history is presumably similar to her Earth-616 counterpart's. When the super-powered machine called the Unmaker began causing devastation across the globe, Kamala aided civilians that were caught in the devastation. The Unmaker was eventually defeated, but a portal left open by Doctor Strange unleashed an EMP that devastated technology all over the world.[1]
With technology destroyed along with the devastation caused by the Unmaker, wars and chaos erupted across the world, killing billions. Ms. Marvel was one of many heroes who convinced people to stop fighting with one another.[2]
