Cammy was cloned from the DNA of Street Fighter villain M. Bison and genetically engineered to be an assassin in Bison's army. When she uncovered the truth about who she was, she rebelled and escaped from the headquarters of Bison's Shadaloo headquarters, but not unscathed. Having suffered severe cranial injuries, Cammy lost her memory. Eventually she found herself in the service of Delta Red, an elite English military squadron, where her skills as an assassin were put to use. After encountering Bison in the course of Delta Red operations, Cammy's memory returned, leaving her distraught.

Defeating Bison, however, granted her a new lease on life, and she continued her career with Delta Red intending to live her own life. When rumors of Bison's return begin to emerge, Cammy is assigned to infiltrate the Street Fighter tournament and investigate what's really going on.Kotaku: Cammy Training Guide Page
