''Street Fighter Alpha: The Animation''--released in Japan as ''Street Fighter Zero: The Animation'' (ストリートファイターZERO?) and also known as ''Street Fighter Alpha: The Movie''--is a 1999 [[{{OriginalVideoAnimation}} OVA]] film loosely based on the ''VideoGame/StreetFighterAlpha'' series. It was directed by Shigeyasu Yamauchi, with character designs by Yoshihiko Umakoshi. An English adaptation was produced by Creator/MangaEntertainment and released in 2000.

The film commemorates the tenth anniversary of the arcade release of the original ''VideoGame/StreetFighterII''. It is not a prequel or sequel to either ''Anime/StreetFighterIITheAnimatedMovie'' or ''Anime/StreetFighterIIV'', but an independent installment, although a handful of voice actors from the previous adaptations reprised their roles for the English version.

The story starts when Ryu is thinking of Gouken's death, then intervenes in a shoot-out to help Chun-Li. Afterwards, he and Ken are contacted by a boy named Shun -- who claims to be Ryu's younger brother! Neither is really convinced by Shun's claim, but they decide that there's no harm on letting the boy tag along with them. Things start getting hairy, however, when the three decide to enter the Street Fighter tournament: not only Ryu is starting to show more and more sympthoms of the Satsui no Hado awakening within him, but Shun's background and the people behind it start to unfurl...

!!Tropes in the anime include:

* AttemptedRape: Sakura almost goes through this when she visits a bar and tries to fight against some of the customers. Thankfully, [[BigDamnHeroes Ken saves her before they could even have their way with her]]. The dialogue from the thugs heavily implies this as they start grabbing her:
--> '''Man A:''' "Hehe... That was fun, let's play some more."
--> '''Man B:''' "We'll have a good ol' time!"
* BadassAdorable: Shun, it later gets subverted when he brutally beats up street thugs and is really a CreepyChild.
* CanonForeigner: Shun, Wallace and Dr. Sadler.
* ContinuityNod: Fei Long's director is the same one from ''Street Fighter II V''.
* CreepyChild: Shun at first looks like your average kid, but as the movie develops he gains more than one trait of this.
* DiedInYourArmsTonight: [[spoiler:Shun's death in Ryu's arms.]]
* DistressedDamsel: Sakura when she tried to fight a group of drunkards, Ken saves her. She later gets a broken leg after the tower holding the tournament collapses, Ken has to carry her to safety.
* DistressedDude: Shun spends the second half of the movie held captive by Dr. Sadler.
* {{Flanderization}}: Poor Dan gets curbstomped even more than usual.
* GenericDoomsdayVillain: Dr. Sadler and his cyborg have literally no other characterization besides being fodder for Ryu's Hadouken. And besides Ryu's Hadouken, [[InvincibleVillain nothing else hurts them]].
* GroinAttack: [[spoiler: Chun-Li, of all people, suffers a vicious shot in her pelvic region by Romanov, Dr. Saddler's cyborg while she, Ken, and Birdie were fighting it. The quick reaction on her face underscores it. ''Ouch!'']]
* InfantImmortality: [[spoiler:Averted, Shun, a young pre-teen boy, dies at the end of the movie.]]
* LongLostSibling: Shun claims to be Ryu's younger brother. He and Ken don't believe him at first, yet they still let him hang around them... but there are also some ''really'' troubling details about the kid [[spoiler: like him apparently being able to summon ''the Satsui no Hado''...]]
* MorallyAmbiguousDoctorate: Dr. Sadler.
* NotEvenBotheringWithTheAccent: The English dub gives Birdie an American accent when he's supposed to be British.
* RecursiveReality: Sakura is seen playing ''VideoGame/SuperGemFighter'', a game she herself is in.
* StealthMentor: Rose tries to be this to Ryu.
* SuperpoweredEvilSide: The Satsui no Hado.
* WouldHurtAChild: Zangief during his match with Shun, if it weren't for Ryu interrupting the fight, he would've ''killed'' him!
