History
Gert Yorkes' history is presumably similar to her Earth-616 counterpart's. When a super-powerful machine called the Unmaker unleashed earthquakes that devastated the Earth, Yorkes aided civilians in Los Angeles caught in the devastation. The Unmaker was eventually defeated, but an EMP unleashed by a portal accidentally left open by Doctor Strange wiped out technology all over the world.[1] What became of Yorkes afterward is unrevealed.
