[[caption-width-right:300:This is how fans see the relationship between Capcom and Arika.]]

In 1996, ''Street Fighter EX'' was developed by Arika (a company founded by ''VideoGame/FinalFight'' and ''VideoGame/StreetFighterII'' co-designer Akira Nishitani) and published by Creator/{{Capcom}} as an attempt to bring the normally 2D ''Franchise/StreetFighter'' series into true [=3D=]. The game saw the return of Ryu, Ken, Chun-Li, Guile (in his first game since ''Super Street Fighter II Turbo''), Zangief, Akuma and M. Bison. [[CanonForeigner New characters]], who are owned by both Capcom and Arika, were also added. These characters include:
* Hokuto, Japanese Kobujutsu master and archer
* Cracker Jack (just Jack in later installments), American bouncer
* Doctrine Dark, AxCrazy German mercenary
* Skullomania, Japanese salaryman turned hero
* Pullum Purna, SpoiledSweet Saudi princess
* Allen Snider, American ex-Karate champ
* Blair Dame, Monegasque {{Ojou}} and socialite
* Kairi, the long-lost amnesiac brother of Hokuto.
* Darun Mister, Indian pro wrestler
* Garuda, demon samurai

Two [[UpdatedRerelease Updated Re-releases]] were created as ''Street Fighter EX Plus'', adding dark versions of Ryu (Evil Ryu) and Hokuto (Bloody Hokuto), and Cycloid-β (Beta) and Cycloid-γ (Gamma), two cyborg {{ditto fighter}}s with no faces (Gamma's a wireframe). UsefulNotes/PlayStation-exclusive ''Street Fighter EX Plus α'' added familiar faces Dhalsim and Sakura.

The game played similar to ''VideoGame/StreetFighterAlpha'', but with the addition of side-stepping (albeit only as an aesthetic element of certain specials; unlike, say, ''VideoGame/{{Tekken}}'', it was not a universal mechanic), guard-breaking attacks that makes the opponent temporarily dizzy, and special moves and Super Combos that can be cancelled into other Super Combos.

In 1998, ''Street Fighter [=EX2=]'' was released and added Excel Combos, custom combos similar to the ones seen in the ''Alpha'' series. This game also marks the first time that a ''Street Fighter'' game within its own sub-series removes characters from the roster as Akuma, Sakura, M. Bison, Pullum, Darun, Allen, and Blair were cut. In their place came ''Street Fighter II'' veterans Blanka and Vega and four newcomers:
* Hayate, Japanese [[MasterSwordsman swordsman]]
* Sharon, European secret agent [[TheGunslinger gunslinger]]
* Nanase, Hokuto's [[SimpleStaff staff-wielding]] sister
* Shadowgeist, masked [[AntiHero anti-hero]]

''Street Fighter [=EX2=] Plus'' brought back Pullum, Darun, and Bison and then added Ryu's rival Sagat, Area (a young inventor with a giant mechanical arm), and Vulcano Rosso ([[LiteralMetaphor fiery]] Italian fighter). Hayate was removed from the arcade version of ''[=EX2=] Plus'', but returned for the [=PlayStation=] version. ''[=EX2=] Plus'' also added Meteor Combos, a precursor to the Ultra Combo system later introduced in ''VideoGame/StreetFighterIV''. Aside from Super Cancels, ''[=EX2=]'' allowed for Super Combos to be cancelled into a Guard Break (Cancel Break, which could then be followed up by another Super Cancel if the player had enough/infinite meter) or a Meteor Combo (if the game allowed the player at the time to have infinite super meter or more than three bars).

In 2000, ''Street Fighter [=EX3=]'' came out exclusively for the UsefulNotes/PlayStation2. A tag team system was added, complete with various new gameplay mechanics such as [[CombinationAttack Meteor Tag Combos]], but it wasn't well-received. Everyone from ''[=EX2=] Plus'' (except Hayate) returned, as did Sakura. Ace, the sole new character for the game, was a character that could have [[PowerCopying moves from other fighters]] [[AllYourPowersCombined added to his move list]] at the player's discretion. Guard Breaks were replaced by the somewhat similar Surprise Blow, losing their unblockable properties but able to stun crouching opponents and floor airborne ones as well as costing no meter to use, while Momentary Combos, two special inputs for each character allowing them to cancel from one special move to another unique special with the press of a precisely-timed single punch or kick, were added.

In 2011, [[http://www.fightersgeneration.com/np8/arika-fightingsample.png screenshots]] and [[https://www.youtube.com/watch?v=7Nxb-mcn6wg gameplay footage]] of a test project for the UsefulNotes/Nintendo3DS known as ''Fighting Sample'' (alternatively, ''Project EX'') featured [[CanonForeigner (some of) the cast]] of the ''EX'' series. However, this only proved to be a tech demo of sorts, and Arika currently has no plans to make it into an actual game. On September 19, 2016, Capcom [[http://game.capcom.com/cfn/sfv/column-130853.html released a profile and artwork on Darun Mister]] which also mentioned Pullum Purna and connected him to the plot of ''VideoGame/StreetFighterV''.

[[SequelGap In 2017]], Arika [[https://twitter.com/miharasan/status/847840152223268864 announced]] a follow-up to ''Street Fighter EX'' and its [[SpiritualSuccessor loose spin-off]] ''VideoGame/FightingLayer'' under the WorkingTitle (later made the official title) of ''VideoGame/FightingEXLayer'' [[note]]as it incorporates a mix of gameplay mechanics from both titles, such as the Guard Breaks of ''Street Fighter EX'' and sidestepping and walled arenas from ''Fighting Layer''; despite this, it is colloquially known by fans as ''Street Fighter [=EX4=]''[[/note]] with [[https://www.youtube.com/watch?v=o2x8c-RFGnA gameplay footage]] to show off. The announcement, [[MilestoneCelebration meant to celebrate Arika's extended 20th anniversary]] [[note]]the company was founded in 1995[[/note]], came on AprilFoolsDay, [[DidntThinkThisThrough leading many to initially believe it was a joke]]. Others thought the game looked [[OverlyPrePreparedGag way too real and polished]] to possibly be a joke (explained in part [[https://www.youtube.com/watch?v=IuXXbQJHqgc#t=2m27s here]]), and as it turns out, [[https://www.youtube.com/watch?v=U1UShcCfcl4 the game is indeed playable]] and was even [[http://shoryuken.com/2017/03/31/its-real-check-out-arikas-livestream-of-their-new-street-fighter-exfighting-layer-based-fighter/ live]][[http://www.fightersgeneration.com/screens2/arika-sfex-april2017.htm streamed]] [[https://pvplive.net/c/arika-confirms-new-fighting-game-for-20th-annivers later that day]] at [[https://www.facebook.com/co.arika/posts/1334036619965033 a promotional exhibition event-slash-location test]] featuring Arika staff members and notable ''Street Fighter'' player [[UsefulNotes/FGCAces Ryota "Kazunoko" Inoue]]. (According to Akira's vice president Ichiro Mihara, the development of ''Fighting EX Layer'' being hidden for so long was, in fact, the joke.) At EVO 2017, the game was confirmed to be under development for the UsefulNotes/PlayStation4 with a simultaneous launch in 2018.

!!Tropes distinct to, or introduced in, this game:

* TwoAndAHalfD: Contrary to popular belief, and much like ''[[VideoGame/StreetFighterIV IV]]'' would do years down the road, the combat system remained strictly 2D, the only changes being the 3D polygonal models and certain moves taking advantage of more dynamic camera angles as opposed to being set purely on a 2D plane.
* BlindIdiotTranslation: The original game had Blair's nameplate under the life gauge spelled as "Brair."
* TheBusCameBack: Bison, Pullum, and Darun were retired in ''[=EX2=]'' before they returned in ''[=EX2=] Plus''. Sakura was exclusive to ''EX Plus α'' until she was brought back in ''[=EX3=]''.
* CanonForeigner: The characters introduced in this series belong to Arika. In ''Street Fighter [=EX2=]'', they retconned the backstories of most of the new characters to distance them from the canon characters, while Blair and Allen were actually included in a non-Capcom Arika-developed fighting game titled ''VideoGame/FightingLayer'' that never left the arcade. An interview with Seth Killian states that both Capcom and Arika own the ''EX'' characters, and that the only reason why a new ''EX'' game hasn't been made was Capcom's wish to have Arika make it happen.
* CanonImmigrant: As of ''Street Fighter V'', it's revealed on Capcom's CFN website that [[spoiler:Zangief gave his Chess Piece to Darun Mister to keep safe]]. The CFN website has since added other characters from the ''EX'' series, implying that while their game of origin has no place in the ''Street Fighter'' canon, the characters themselves are still a part of the ''Street Fighter'' universe, even if they never show up as playable characters again.
* CombinationAttack: The [[https://www.youtube.com/watch?v=_gcSlEaLg4w Meteor Tag Combos]] from ''[=EX3=]''.
* EasterEgg:
** ''EX Plus α'' [[http://strategywiki.org/wiki/Street_Fighter_EX/Secrets#Character_quirks was swarming with them,]] ranging from an alternative version of Hokuto dressed as a {{Miko}} to Ryu's headband continually growing larger after winning five consecutive matches to C. Jack's aluminum baseball bat to Akuma's prayer beads breaking apart and flying off of him if struck by a Super Combo.
** ''[=EX3=]'', upon either completing Original Mode eight times with Sakura on Normal/Hard or earning all of the bronze medals, provides the option of having Sakura featured as the announcer of your matches.
* FictionalCountry: If the map in vanilla ''[=EX2=]'' is any indication, every stage in the game is set in a fictitious country meant to stand in for a real life one. Stranger still is the fact that ''Street Fighter'' heavily features real life locations, with most of the characters (''EX'' cast included) explicitly hailing from an actual nation.
* GaidenGame: The WorkingTitle of the first game was actually ''Street Fighter Gaiden''.
* GratuitousEnglish:
** Various characters aside, ''[=EX3=]'' featured the mildly Engrishy '''[[ItemGet YOU GOT MEDAL]]''' when obtaining medals in Original Mode.
** Even the naming conventions for some of the music aren't safe. Take Garuda, for instance. In ''EX'' and ''[=EX3=]'', his theme is entitled "Stronger." That's not bad by any means, but his ''[=EX2=]'' boss theme and ''[=EX3=]'' Original Mode mid-boss theme are respectively "More Stronger" and "Great Stronger" as opposed to "Even Stronger," "More Strong," "Strongest," etc.
* LimitBreak: The Meteor Combos, introduced in ''[=EX2=]''.
* MiniGameCredits:
** The practice session in ''[=EX2=] Plus'' with a Cycloid after winning the fight over M. Bison.
** Beating up random {{Mooks}} in ''[=EX3=]''.
* MovesetClone:
** Three sets: the ex-TropeNamers Ryu and Ken, Allen and Kairi (who are similar to Ryu and Ken), Zangief and Darun.
** A case could also be made for Skullomania and Shadowgeist, the later of whom made his debut in the second game.
* PutOnABus: Akuma, Blair, and Allen in all the entries after ''EX Plus α''. Hayate was retired in the arcade version of ''[=EX2=] Plus'' for unknown reasons (although he was brought back as a bonus character in the [=PS1=] version).
* {{Retcon}}: The original backstories for most of the new characters featured ties to numerous established ''Street Fighter'' characters (Hokuto is a student of the Bushin school of ninjutsu, Doctrine Dark was a former subordinate of Guile who was injured by Rolento, Jack is a former Shadaloo enforcer, Allen lost to Ken once, Pullum Purna's family has ties to Shadaloo and Darun is a rival to both Zangief and [[VideoGame/SaturdayNightSlamMasters Victor Ortega]]). In ''Street Fighter [=EX2=]'', all of these backstories were rewritten to downplay and even contradict these connections (such as claiming that Hokuto and Kairi's school is known as the Mizukami style and that Doctrine Dark's insanity was due to him being raised as a child mercenary) once it was established that Arika owned all of the new characters. Capcom's CFN website would later take elements from both backstories, i.e. saying Hokuto is descended from Bushin ninjas as well as being an heir to the Mizukami clan.
* SharedUniverse: With ''VideoGame/FightingLayer''.
* {{Shotoclone}}: Ryu, Ken, Sakura, Akuma, Allen, and Kairi.
** DivergentCharacterEvolution: Mostly started in the second game, although Allen was unique from the start with the inclusion of kickboxing moves, his Justice Fist (which could [[AttackReflector deflect projectiles]]), and two command throws. On the other hand, Kairi mostly played like a more balanced Akuma at first, although with Akuma's [[PutOnABus absence]] starting in ''[=EX2=]'', Kairi essentially ''became'' Akuma. However, he did have his own odd quirks (such as his projectile not being thrown like a typical Hadoken [[note]]it instead appeared onscreen and stayed there for about half a second, its distance being gauged by the strength of the punch button used[[/note]] and the [[KamehameHadoken Shouki Hatsudou]], a [[LimitBreak Meteor Combo]] [[HPToOne that brought his health down to a tiny sliver]] and [[DeathOrGloryAttack was best used as a finisher]]).
* SituationalDamageAttack: Cracker Jack's Final Punch is a ChargedAttack using three punch/kick buttons; depending on how long you charged it, it can deal low to massive damage (more than half a life bar, even). As Jack's moveset is lifted almost wholesale from [[VideoGame/StreetFighterII Balrog]], the Final Punch is his answer to Balrog's Turn Punch.
* SkeletonMotif: Skullomania wears a full body suit that has skeletons painted over his whole body. Subverted in that not only he's a hero, he's a clear-cut and rather silly one as well.
* SpriteMirroring: Averted; all the characters are 3D models.
* TagTeam: In ''[=EX3=]''.
* TeamSpirit: With ''[=EX3=]''[='s=] partner matches, if one character is defeated, their accumulated super meter gauge will be transferred to the remaining teammate in what is known as Emotional Flow. At this point, the second character will now be able to hold up to six bars of super meter as opposed to the normal three.
* UnblockableAttack: The Guard Break. In ''[=EX3=]'', this was replaced by the Surprise Blow, which no longer cost super meter, but could be blocked. It still stuns the opponent, but only if they are crouching; if it successfully strikes a midair opponent, they'll immediately be knocked to the ground instead of how Guard Breaks would pop them up into the air for a juggle.
