Ada Wong (Resident Evil 6)

Ada remains somewhat of an enigma, her employment, her aims and her true allegiance is somewhat unknown. In 1998 she went to Raccoon City to acquire a sample of the G Virus, and it was there when she first met Leon S. Kennedy. Currently, her mission is to infiltrate a submarine on the orders of Derek C. Simmons, a man she hasn't heard from since the Raccoon City incident.
