-- '''Announcer''', ''Alpha 3''

In 1995, Capcom released a long-awaited real sequel -- or rather, a ''[[{{Prequel}} prequel]]'' to ''VideoGame/StreetFighterII'', '''''Street Fighter Alpha: Warriors' Dreams''''' ('''''Street Fighter Zero''''' in Japan, Asia, and South America). With a distinctive anime-styled look based on ''[[Anime/StreetFighterIITheAnimatedMovie Street Fighter II: The Animated Movie]]'', ''Alpha'' takes place between the first two ''Street Fighter'' games, and expands the {{backstory}} of many of the major characters. The game also features returning characters from the original ''VideoGame/{{Street Fighter|I}}'' (who were merely computer-controlled opponents, namely Thai-kickboxer Adon and British punk Birdie), as well as characters from Capcom's beat 'em up ''VideoGame/FinalFight'' (ninja loner hero Guy and criminal samurai wannabe Sodom) and also introduced a few new characters: Dan Hibiki (the quintessential JokeCharacter and TakeThat to ''Street Fighter'' copycat ''[[VideoGame/ArtOfFighting Art of Fighting]]''); American soldier Charlie (who was introduced as Guile's missing friend, and was called Nash in Japan); and Italian fortune teller Rose. All of them joined Ryu, Ken, Chun-Li, Sagat, M. Bison and Akuma.

'''''Street Fighter Alpha 2''''' was released less than a year later in 1996, which expanded upon the previous game, with the addition of a custom combo system, new stages and endings, and five additional characters. Among these new characters were Sakura Kasugano (a Japanese schoolgirl who idolizes Ryu), Rolento from ''Final Fight'', and Gen from the original ''Street Fighter'', as well as returning World Warriors Zangief and Dhalsim. The American arcade version added Evil Ryu to the roster, along with extra versions of Zangief and Dhalsim (in addition to Shin Akuma and Classic Chun-Li). ''Alpha 2'' was re-released in Japanese arcades under the title of ''Street Fighter Zero 2 Alpha'', which included all the added characters from the American release, extra versions of all the ''Street Fighter II'' characters (including Classic Chun-Li), as well as new moves for some of the returning characters and minor changes to the fighting system (particularly in the Custom Combo system, which were easier to perform, but now consumed a larger portion of the Super Combo gauge). ''Zero 2 Alpha'' was ported to home consoles as ''Alpha 2 Gold'', which added Cammy to the roster as well (although she was only playable in the Versus and Training modes at first).

'''''Street Fighter Alpha 3''''' finished off the prequel sub-series in 1998, introducing a selectable fighting styles called "isms". In addition to Cammy, the ''Alpha 2'' roster were joined by newcomers Karin Kanzuki (Sakura's rival from the manga ''Sakura Ganbaru!''), Rainbow Mika (a Japanese female wrestler) and Juni & Juli (M. Bison's female bodyguards), along with Cody from ''Final Fight'' and most of the ''Street Fighter II'' warriors who were absent in previous ''Alpha'' titles (namely Blanka, E. Honda, Balrog and Vega). The console versions (and a later ''Upper'' revision released only in Japanese arcades) brought back Guile and the rest of the "New Challengers" from ''Super Street Fighter II'' (Fei Long, T. Hawk and Dee Jay), gathering the entire ''Super Street Fighter II Turbo'' roster. A GameBoyAdvance port was released in 2002, adding Eagle, Maki and Yun (with [[AssistCharacter his brother]] Yang) fresh from their appearance in ''[[VideoGame/CapcomVsSNK2MarkOfTheMillennium Capcom vs. SNK 2]]''. Finally, in 2006, Ingrid from ''VideoGame/CapcomFightingEvolution'' was added in the PSP version.
!!Tropes Distinct To, Or Introduced In, This Game:
* AcheyScars: The scar on Sagat's chest glows whenever he is confronted by Ryu. In ''Alpha 2 Gold'' and ''Alpha 3'', he gains a super which allows him to draw upon the feelings of anger and hatred invoked by his scar and buff the damage output of his next Tiger Blow.
* AdaptationExpansion:
** Cammy was added to the roster in ''Alpha 2 Gold'' (the console version of the Asia-only ''Zero 2 Alpha'') after her [[MarthDebutedInSmashBros appearance]] in ''VideoGame/XMenVsStreetFighter'', although she did not have a proper in-game storyline until the game was re-released for the PlayStation2 as part of the ''Street Fighter Alpha Anthology''.
** When ''Alpha 3'' was ported to home consoles, not only did the home versions feature four extra characters (Fei Long, T. Hawk, Dee Jay and Guile), but the sub-bosses (Balrog, Juni and Juli) were given proper storylines and endings that they didn't get in the original arcade release.
** The GBA version of ''Alpha 3'' feature three characters not in the prior arcade and console versions: [[VideoGame/FinalFight Maki]], [[VideoGame/StreetFighter Eagle]] and [[VideoGame/StreetFighterIII Yun]], all based on their ''Capcom vs. SNK 2'' incarnations. Unfortunately, the GBA version is simplified and watered-down in other areas, including the lack of storyline. When the game was ported to the PSP later, the same extra characters were added, along with Ingrid from ''Capcom Fighting Evolution'', and all four were given storylines and endings.
* AnnouncerChatter: The aforementioned ''Alpha 3'' announcer. Most fighting games fans [[MemeticMutation know his lines by heart]].
--> "Nobody blink, go for broke!"
* BodyguardBabes: While pretty much any member of the Bison Elite Guard ([[AmazonBrigade the]] [[{{Brainwashed}} Dolls]]) may qualify, Juni and Juli both serve this function in-game in the arcade mode of ''Alpha 3''.
* BroadStrokes: Contrary to popular belief, ''Alpha 2'' isn't really so much of a remake of the original ''Alpha'' as it is both a continuation and a remake. Some of the character endings in ''Alpha 2'' (like Sodom's, Ken's, Rose's, and Sagat's) are rough continuations of their original endings from the first ''Alpha'', while others (like Dan's and Adon's) are hard to reconcile with their originals. Charlie's endings in the first two ''Alpha'' games don't completely sync in with the fact that he is still alive in ''Alpha 3''.
* TheCameo: [[http://capcomdatabase.wikia.com/wiki/File:StreetFighterAlpha2-USA(Ken).png Ken's stage]] in ''Alpha 2'' features appearances from Pure the Mage (''Capcom World 2''), [[VideoGame/{{Darkstalkers}} Morrigan, Felicia, Hsien-Ko, Mei-Ling, and Lord Raptor]], [[VideoGame/SaturdayNightSlamMasters Biff Slamkovich and Jumbo Flapjack]], [[VideoGame/ForgottenWorlds Unknown Soldiers 1P & 2P]], [[VideoGame/AlienVsPredatorCapcom Linn Kurosawa]], [[VideoGame/CaptainCommando Captain Commando and Ginzu]], [[VideoGame/{{Strider}} Strider Hiryu]], [[VideoGame/LegendaryWings Michelle Heart]] and Capcom CEO Kenzo Tsujimoto as a butler. They are most likely just some very convincing {{cosplay}}ers.
* CanonDiscontinuity: The events of ''Final Fight 2'' are hard to fit into the backstory of the ''Alpha'' series without invoking a bit of {{fanwank}}ery. Mainly the fact that Guy has two different masters (Genryusai in ''Final Fight 2'', Zeku in the ''Alpha'' series) and Rolento's allegiance (he was still employed by Mad Gear in ''Final Fight 2''; in ''Alpha 2'', he has left the gang to form his own organization). That still didn't prevent Maki from becoming a CanonImmigrant and being placed into the character roster of the portable versions of ''Alpha 3''.
* CanonImmigrant: While Gouken was technically mentioned in Akuma's original backstory published during the release of ''Super Street Fighter II Turbo'', his appearance in Akuma's ending in the original ''Alpha'' was his (and Goutetsu's) first and only appearance in the series until ''VideoGame/StreetFighterIV'' a decade later. Karin Kanzuki was originally Sakura's rival from a Sakura-centric spinoff manga titled ''Sakura Ganbaru!''. Evil Ryu, the SuperpoweredEvilSide of Ryu, was originally a creation of Masahiko Nakahira's ''Street Fighter Alpha'' manga published by Gamest.
* CharacterRosterGlobalWarming: Birdie and Zangief are the only MightyGlacier characters.
* CompilationRerelease: ''Street Fighter Alpha Anthology'' for the {{PlayStation 2}}, featuring all three ''Alpha'' games plus ''Alpha 2 Gold'' and ''Alpha 3 Upper'' as well as ''[[VideoGame/SuperGemFighter Super Gem Fighter: Mini Mix]]''.
* ContinuityCameo:
** The Mad Gear gang from ''Final Fight'' can be seen in Sodom's ending in the first game, as well as spectators in Guy's stage in ''Alpha 2'' and ''3''.
** A billboard advertising a wrestling match between [[VideoGame/StreetFighterIII Hugo]] and an unknown opponent can be seen in Cody's stage in ''Alpha 3''.
** Ken's stage in ''Alpha 2'' is a set on a cruise ship filled with other Capcom characters (or at least very convincing cosplayers) attending Eliza's birthday party.
* CounterAttack: The Alpha Counters. A few other characters, like Karin and Dan, have attack reversals as well.
* ClearMyName: In ''Alpha 3'', Fei Long is mistakenly accused of being involved in Shadaloo's drug trades, and he goes to see what's going on. Yun's story mode has him actually believing the accusations and setting off with Yang to capture Fei Long himself. [[spoiler: After the Yun vs. Fei Long mid-boss fight, Fei Long explains what happened to Yun, so they decide to team up and protect Hong Kong from the real culprit: Bison. Then, Bison himself shows up: Fei Long stays behind to fight him and Yun goes against Juni and Juli, then after Bison when Fei Long loses.]]
* {{Crossover}}: The series can be seen as a crossover in a technical sense, since it was the first time in the franchise the ''Street Fighter II'' roster was pitted against characters from the first ''Street Fighter'' and ''Final Fight''. ''Alpha 3 MAX'' adds in ''Street Fighter III'' with Yun.
* CutSong: [[http://www.youtube.com/watch?v=CkH9Ybg3SCc This badass gem]] from the Japanese version of ''Street Fighter II: The Animated Movie'' 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.
* DoomedByCanon: Charlie always dies at the end of each ''Alpha'' game. Because otherwise, what else will inspire Guile to pursue his revenge on M. Bison? This was almost averted in ''Alpha 3'', where Charlie actually survived his ending, but the console version "fixed" this by adding Guile to the roster and having Charlie die in his ending instead.
* EarlyBirdCameo: A few of the characters made background and ending cameos before becoming proper playable characters in the series.
** Balrog and Vega can be seen in both of Sagat's endings in the first two ''Alpha'' games.
** Fei Long appears as a spectator in Dan's stage in ''Alpha 2''.
** Rolento can be seen among the former Mad Gear Gang members gathered by Sodom in his ending in the first ''Alpha'' game.
** E. Honda appears in Sodom's ending in ''Alpha 2''.
** Cody (and his girlfriend Jessica) appears in Guy's stage in ''Alpha 2''. When a female fighter (Chun-Li, Sakura, Rose or Cammy) is in the stage, Cody will shift his attention away from Jessica and into the fighter, causing Jessica to get jealous. She will then slap him in order to regain his attention.
* EpisodeZeroTheBeginning: Due to its title in Japan.
* HumongousMecha: The Buddha statue from ''Alpha 3''.
* LoadsAndLoadsOfCharacters: By the time ''Alpha 3'' hit the home versions, the cast included the entire ''Super Street Fighter II Turbo'' roster, a good chunk of characters from the first ''Street Fighter'' and ''Final Fight'', and a handful of original characters. The GBA version even snuck in Eagle, Maki and Yun from ''Capcom vs. SNK 2'', while the later PSP version added Ingrid from ''Capcom Fighting Evolution'' as well.
* NintendoHard: This series is particularly unforgiving.
* OutOfFocus: When this series came around, this happened to nearly every character from ''Street Fighter II''. Ryu, Ken, Chun-Li, Sagat and M. Bison had been around since the first game, but Dhalsim and Zangief didn't appear until ''Alpha 2'', Cammy returned in ''Alpha 2 Gold'' as a Vs./Training mode-only character before making a proper appearance in ''Alpha 3'' along with E. Honda, Blanka, Vega and Balrog (who all had ending cameos in previous ''Alpha'' and ''Vs.'' games), and eventually Fei Long, Dee Jay and T. Hawk returned in the console versions of ''Alpha 3''. Surprisingly, it took Guile, who was often seen by American fans as lead character in ''II'', until the console version of ''Alpha 3'' to return. Even then, he was a secret character.
* ProductPlacement: Rolento's ''Alpha 2'' stage has a giant mural and billboard for Fujitsu computers.
* RecursiveCanon: A Japanese poster for ''Street Fighter II: The Animated Movie'' can be seen in Ryu and Guy's stage in the first ''Alpha'' game.
* RemixedLevel: Every character in the first game shared a stage.
* RetCanon: The ''Alpha'' series feature a great deal of visual nods to ''Street Fighter II: The Animated Movie''. This includes:
** The more muscular design of M. Bison compared to his original lean look in the early ''II'' games (although, he did have muscular design in the character art for ''Super Street Fighter II'').
** The design of Bison's VTOL aircraft, which is even used as the setting of his stage in ''Alpha 2''.
** The two-on-one hidden game mode in the first ''Alpha'' where two players as Ryu and Ken must fight a computer-controlled M. Bison. The Japanese version even plays a Q-Sound rendition of "Itoshisato Setsunasato Kokorozuyosato", the battle theme from the original Japanese version of the movie.
** The stormy battle scene from Ryu and Sagat's opening battle from the film is used as the stage for Sagat's final boss battle with Ryu in ''Alpha 2''.
* {{Retcon}}: Far, ''far'' too many to count, but the most significant one might be changing Sagat from the loser to the ''victor'' of [[VideoGame/StreetFighterI the first World Warrior Tournament]] and subsequently shoehorning in [[SoreLoser Evil]] [[SuperPoweredEvilSide Ryu]].
** Alpha 3, for all intents and purposes, set in stone the story that the games still follow.
* SeanConneryIsAboutToShootYou: Ryu and Ken throw their Hadōkens simultaneously towards the screen in the opening sequence of ''Alpha 2''.
* SmurfettePrinciple: The first ''Alpha'' only had two female fighters (Chun-Li and Rose) among the game's roster of thirteen. This gradually increased with the addition of Sakura among the five new fighters in ''Alpha 2'', followed by the return of Cammy in ''Alpha 2 Gold'' and then by the addition of Karin, R. Mika, Juni and Juli among the nine new fighters (thirteen in the console ports) in ''Alpha 3'', a total of 8 women among 32 fighters (literally 25% of the roster). That's not even including the addition of ''Final Fight 2''[='s=] Maki and ''Capcom Fighting Evolution''[='s=] Ingrid in the portable versions.
* SlippedTheRopes: Cody in ''Alpha 3'' is a prisoner who makes a habit of breaking out of jail. He's handcuffed. In his taunt, he slips out of the cuffs just to show he can and then puts them back on.
* TagTeam: A 2-on-1 tag-team system, known as "Variable Battle" was introduced in the PSP version.
