A younger version of Cammy appears as an assassin working for Bison's Shadaloo organization, with the codename "Killer Bee" (and in later games described as one of the "Shadaloo Dolls"), first in "Street Fighter Alpha 2 Gold", where she appears as a hidden character available exclusively in the second player and training modes (however, this would be rectified in "Street Fighter Alpha Anthology" where she would be fully playable in Arcade mode with a complete storyline and ending), and then in "Street Fighter Alpha 3", where she is a full-fledged playable character. In "Alpha 3", Cammy is revealed to be a clone created from M. Bison's DNA. The Game Boy Advance version of "Super Street Fighter II Turbo: Revival" and the Xbox Live and PSN remake "Super Street Fighter II Turbo HD Remix" take into account this revelation in their versions of Cammy's ending.
