STORY
At a prominent Swiss Hospital, Dr. Ziegler earned her position as head of surgery for her brilliant skills and knowledge of medicinal practices. Soon after, she helped pioneer a scientific breakthrough in nanobiology that drastically improved healing practices. This caught the attention of Overawtch and lead to a recruitment for her skillset.
Hesitant at first because Overwatch appeared to be a military organization, Ziegler agreed to join despite losing her parents because of war. She saw this as an opportunity to use her skills and save people on a much larger scale than her current position. She became Overwatch's head of medical research and eventually piloted the Valkyrie swift-response suit to tend to required healing in frontline crises.
Eventually however, Overwatch was no more, but Dr. Ziegler still remained faithful to her practice and continued to help those affected by war.
