History
In the seventh life of Moira X, Emma Frost was a teacher at the Massachusetts Academy. Publicly known as a mutant, she and her student were invited to a congressional hearing regarding Dr. Hank Pym's Ultron defense robots in Washington, D.C.. During the hearing, Henry Gyrich killed by time-traveling Moira MacTaggert, which prompted Pym to activate his Ultron units and summon them to his location. The Ultrons went on a killing spree, creating mayhem and killing many civilians, including Emma's students. She herself survived long enough to see her skin turn into a diamond form and was found by time-traveling X-Men. She opened her mind to show them what had happened twenty minutes ago, only to pass away shortly after.[1]
