* CutSong: [[http://www.youtube.com/watch?v=CkH9Ybg3SCc This badass gem]] from the Japanese version of ''Anime/StreetFighterIITheAnimatedMovie'' plays during the ''Alpha 1'' Dramatic Battle in the Japanese arcade version. This song is not featured in the overseas releases or in the console versions, where it was replaced with M. Bison's theme.
** [[MemeticMutation GARlie]] for Charlie, due to him being as manly as Guile.
** Dan "The Man" Hibiki.
** Sakky, for Sakura.
** Ryu was voiced by Katashi Ishizuka in the first two ''Alpha'' games. Creator/ToshiyukiMorikawa, who also voiced Charlie in all three games, took over the role in ''Alpha 3''.
** Rose was voiced by Yuko Miyamura, who also voiced Chun-Li in all three games, in the first two ''Alpha'' games. For ''Alpha 3'', the role was taken over by Michiko Neya.
** Cammy was voiced by Susan Hart in ''Alpha 2 Gold'', by virtue of ''VideoGame/XMenVsStreetFighter'', and by Akiko Komoto in ''Alpha 3''.
** Creator/YukoMiyamura voiced Chun-Li, in all three games, and Rose until ''Alpha 3''.
** Creator/TetsuyaIwanaga voiced Ken and Guy in all three games.
** What do Zangief, Gen, Adon, Birdie, and Sodom have in common? They've been voiced by ManOfAThousandVoices Creator/WataruTakagi.
** Creator/TomomichiNishimura voiced M. Bison and Akuma in all three games.
** Toshiyuki Morikawa voiced Charlie in all three games and Ryu in ''Alpha 3''.
** Creator/YujiUeda voiced Vega and Blanka in ''Alpha 3''.
** Creator/KoichiYamadera voiced Cody and Balrog in ''Alpha 3''.
** Akiko Komoto voiced Cammy, a role [[TheOtherDarrin took over]] from Susan Hart in ''Alpha 2 Gold'', Juni and Juli in ''Alpha 3''.
** Interesting enough, the same voice actress mentioned reprised her role as Juni in the recent Street Fighter V, making Akiko Komoto the only voice actress from the age of Zero games to reprise her role as a Street Fighter Zero character(This on the japanese version of SFV)
** Jin Yamanoi voiced Rolento and, by virtue of ''[[VideoGame/CapcomVsSNK2MarkOfTheMillennium Capcom vs. SNK 2]]'', Eagle.
** [[VideoGame/StreetFighterI Joe]] was going to be one of the new fighters in ''Alpha 3'', but was replaced by [[VideoGame/FinalFight Cody]].
** [[http://www.youtube.com/watch?v=sT9T2HRa1Z0 According to Seth Killian (at the start of the video),]] Rolento was initially going to be called Lawrence. Given that his name reads like a badly Romanized version of the name "Laurent" this makes good sense.
** Juni and Juli may have originally been designed to be played at the same time, similar to when you fight them in Arcade Mode when playing Cammy.
** For ''Alpha 3'', Takayuki Iwai, the main musical composer for the game, originally wanted to use a custom CD-based soundboard in order to make a hard rock soundtrack similar to ''VideoGame/GuiltyGear''. Budget constraints forced him to use the standard MIDI Q-Sound system instead.
