Mercy

A guardian angel to those who come under her care, Dr. Angela Ziegler is a peerless healer, a brilliant scientist, and a staunch advocate for peace. She is one of the most gifted doctors in the world when it comes to medical technology, and has applied such technology to her own body. She likes Swiss chocolate and enjoys tea, which she sometimes takes with a nip of brandy after a life-threatening ordeal. She isn't good at making coffee however—Genji was the only Overwatch member who could stand to drink it. She has a low opinion of Vishkar. After obtaining her MD and PHD in Switzerland, Ziegler rose to become the head of surgery at a prominent Swiss hospital before pioneering a breakthrough in the field of applied nanobiology that radically improved the treatment of life-threatening illnesses and injuries. It was this expertise that attracted the attention of Overwatch. She personally met with Commander Jack Morrison at Overwatch HQ. He was impressed with a paper she'd written on nanobiotic healing. She believed that it had the potential to completely revolutionize the way that medical care was given, not just in the examination room, but also throughout the entire structure of the medical profession. She believed that Overwatch would give her the opportunity to quickly get her ideas out into the field.
