Nash first appears as a playable character in "Street Fighter Alpha", a prequel to "Street Fighter II", where he is a first lieutenant in the United States Air Force, assigned to track down Bison and uncover corruption within the American military. Because the events of the "Alpha" series precede "Street Fighter II", Charlie's ending sequence in the original "Alpha", as well as in "Street Fighter Alpha 2", both end with him being killed after defeating Bison: in "Alpha", Bison attacks him from behind when he calls for backup and in "Alpha 2", a corrupt officer piloting his intended backup helicopter shoots him for Bison and sends him falling down a waterfall. "Street Fighter Alpha 3" was initially the sole exception to this convention, which actually has Charlie surviving in his ending, although the later console versions, which adds Guile as a playable fighter, has Charlie's death depicted in Guile's ending instead. His death scene in "Alpha 2", however, is treated by "Street Fighter V" as canon, making Charlie's appearance in "Alpha 3" semi-canonical (As his bio in Alpha 3 states his objective in Alpha 2)
