This character is Guile's dead friend

Nash (Japan) / Charlie (USA): This character is Guile's dead friend. At the end of the game with Guile in Street Fighter II we see how he claims revenge for the death of his friend Nash. But this can only be read in the Japanese version because Capcom America decided to change that name to Charlie (more typical name of an American soldier). Capcom America could hardly imagine that Nash would "resurrect" the Street Fighter Alpha sub-series and would have to change Nash's name to Charlie's over and over again. From Street Fighter V Capcom adapted the full name of this character as Charlie Nash ("Charlie" as name and "Nash" as first name) in an attempt to unify the names of both versions Cosplay Shop
. Because of this, in Street Fighter V the character sometimes refer to him as Charlie or Nash in all versions. However, in Japan he is still called Nash and in the West continues to be called Charlie.
