    C. Viper — USA 
"My gadgets are cheating? How naïve... Nothing in life is fair. Remember that."

Voiced by: Mie Sonozaki (Street Fighter IV, Marvel vs. Capcom 3; Japanese), Michelle Ruff (Street Fighter IV, Marvel vs. Capcom 3; English)

Full name Crimson Viper. A spy from the CIA acting as a mole in Seth's organization. She was sent to gather data on S.I.N. (Shadaloo Intimidation Network) and its BLECE Project, and to stop them. Her real name is Maya and she has a daughter named Lauren.

  • Action Mom: She's stated to have a daughter in the game, and in the tie-in film, the little girl is shown in several scenes. And in the ending animation sequence of her Arcade Mode in Super Street Fighter IV, she meets up with Lauren, giving her a hug and telling her that she loves her.
  • Alternate Company Equivalent: Not so much in her fighting style but in her story, she's arguably Capcom's interpretation of Vanessa from The King of Fighters (both being female secret agents with a family life back at home).
  • Ambiguously Brown: In some artwork. She's likely mixed-race.
  • Animal Motifs: Her code name is Crimson Viper. Her red hair is styled to resemble a snake, with a loose strand forming the tongue, even.
  • Badass in a Nice Suit: Her main outfit.
  • Badass Longcoat: As her alternate costume.
  • Bare Your Midriff: Her default and first alternate costumes, the alternate more so than the default.
  • Bifauxnen: Subverted—When first introduced, her back braid was not seen a lot, and if it wasn't for her breasts, she might've passed as a guy, what with wearing a tuxedo. Now that it's known that she has that braid...
  • Breakout Character
    • Capcom vs. Whatever: She joined the cast of Marvel vs. Capcom 3, being the first of the new Street Fighter characters to be in a Vs. game. This meant she achieved in three years what several Capcom characters have failed to do in many: appear in a Vs. game.
  • Cleavage Window: Divided in two by the tie.
  • Clothes Make the Superman: Her powers come from her clothes.
  • Code Name: Crimson Viper.
  • Combat Pragmatist: Because she uses a battle suit to fight, she's been labeled a cheater and dishonorable to some of the World Warriors. See the win quote at the top of Viper's bio for her response.
  • Combat Stilettos: Her boots are apparently part of her combat suit.
  • Confusion Fu: In the hands of a master, fighting against her is a constant guessing game.
  • Cool Shades: She has big yellow shades.
  • Dark Action Girl: Subverted: she seems to be a reverse mole in regards to S.I.N., and while cold to the other warriors does have a kinder side that she shows to her little girl.
  • Dark-Skinned Redhead: Although, her skin is not that dark.
  • Difficult but Awesome: She's generally thought of to be the hardest character in the game to learn, because her moves demand a very high execution curve. However, her unpredictable mixups and raw speed and power more than make up for it, if she is mastered.
  • The Dragon: She's played as one for Seth in Street Fighter IV and in the tie-in film, but she's apparently a reverse mole instead.
  • Foreign Fanservice: American, and her 98cm bust is the biggest among any female in the series. Ironically, Chun-Li is still bigger in-game.
  • Fragile Speedster: C. Viper is not only quick, but her combos deliver a ton of damage. But what makes her a Fragile Speedster instead of a Lightning Bruiser is that her health is below average like most female characters. And her stun rating is poor as well.
  • Good Hair, Evil Hair: She boasts a delinquent pompadour, hinting at her duplicitous nature.
  • Groin Attack: C. Viper pulls off a rare female version on Cammy in The Ties That Bind. With a fistful of lightning no less.
  • Guile Heroine: Viper works for the CIA, is the reverse mole to S.I.N., investigates Shadaloo, apparently drops anonymous tips to the other fighters, etc.
  • I Have a Family
  • Jerk with a Heart of Gold: She can be kinda icy to the other World Warriors. Still, she is sweet and cuddly with her little daughter as seen at the end of her arcade mode in Super Street Fighter IV.
    • It also shows in some of her win quotes against certain opponents in SSFIV; while most of her comments are rather caustic, some of them have express a genuine interest in and sympathy for her opponents' personal situations.
    (to Guile) "Whose dog tags are those? Ah, I see. You're fighting for a lost friend..."
    (to Ibuki) "I used to skip school all the time, too. Those were the days..."
    (to Hugo) "I'll let you go. Just promise to take good care of your mother."
  • Mysterious Woman: Even provides the page quote.
  • Nothing Personal: She's here on an assignment, nothing more and nothing less.
  • Playing with Fire: Burning Kick? Burst Time? Burning Dance? Does the ring bell?
  • Punch Clock Hero/Punch Clock Villain: She seems to be highly uninterested in fighting, only using this as a means to an end to complete her mission.
  • Rapunzel Hair: Her braid reaches down to the back of her knees.
  • Reverse Mole: Heavily implied that she's a CIA agent working undercover.
  • The Rival: To Chun-Li, every time they encounter each other.
  • Sensual Spandex/Sexy Backless Outfit: Her second DLC costume.
  • Shock and Awe: If Thunder Knuckle is any indication.
  • Shockwave Stomp: Seismic Hammer — She can punch the ground underneath her really hard, generating localized shockwaves at different distances, depending on the strength of the punch used.
  • Statuesque Stunner
  • The Friend Nobody Likes: Her use of gadgets puts her at odds with most of the other fighters. Even Gouken initially has nothing nice to say about her.
  • The Woman In Black
  • X-Ray Sparks: Thunder Knuckle has this effect on her opponents.

    Abel — France 
"Street fighting is all about analysis, prediction, and reaction. That's it."

Voiced by: Kenji Takahashi (Street Fighter IV, Street Fighter X Tekken; Japanese), Jason Liebrecht (Street Fighter IV, Street Fighter X Tekken; English)

A ridiculously tall and large young Frenchman who uses mixed martial arts. He is an amnesiac who was taken in by a mercenary who rescued him from one of Shadaloo's bases. After the mercenary died, he decided to hunt down surviving members of Shadaloo, believing them to be the connection to his lost memories. He enters the Street Fighter IV tournament to find out Shadaloo's connection to the S.I.N. corporation.

  • Apologetic Attacker: More than one of his quotes have him either apologizing to his opponents or showing some worry for their well-being.
  • Cloning Blues: It is hinted in Seth's story mode and Abel's ending that Abel may be a clone of Seth, or perhaps Seth's original.
  • Confusion Fu: One of his unlockable titles is "Mixup Master."
  • Does Not Like Shoes: Only his default costume lacks shoes.
  • French Jerk: Nope.
  • Friend to All Living Things: Super Street Fighter IV introduces his faible for dogs. And in Street Fighter X Tekken, he really wants to pet a bear. Also in that game, he finds aliens, who resemble bears, cute.
  • Gentle Giant: Has a thing for dogs, specially the white puppy he befriends in his Super SFIV prologue. Who happily comes to greet him in his ending, as Abel happily says "It's good to be back home."
  • Good Scars, Evil Scars: While is more apparent in the art for the character than on his actual in-game model, Abel has his body Covered with Scars from head to toe, similarly to Zangief.
  • Gratuitous... Something: His voice in English has a particularly muddled accent that randomly switches from English to French to German to... You wouldn't know he's French if not for the flag in his selection screen picture.
    • Gratuitous French: He now actually uses a little French in his Street Fighter X Tekken appearance - "En garde, s'il vous plaît." ("Get ready please" more or less) and "Aidez-moi!" (Help!) when he tags out.
  • Hair of Gold, Heart of Gold: He has blond hair and is a really Nice Guy. This is also a contrast to Seth with his Bald of Evil.
  • Happily Adopted: By Charlie, who rescued him from Shadaloo and got him a job with a mercenary friend. Although according to Abel, Charlie was less than open about himself
  • Heroes Love Dogs: He befriends a puppy and later adopts it.
  • Laser-Guided Amnesia: Linked to Shadaloo. As such, he's something of an Man Child. Just see the below trope.
  • Lightning Bruiser: Unlike other grappler characters, he's surprisingly not slow. Though, since it's Street Fighter, it's not that much of a surprise.
  • Loony Fan: In IV, his rival battle is against Fei Long. He's a huge fan of Fei Long's movies; when Fei Long meets him in Fei's rival battle, Abel expresses his admiration of the guy by picking a fight with him. You'll laugh when a sound byte of Abel saying, "I've seen all of your movies~!" plays after, say, Abel using his HCB + P command throw on Fei Long.
  • Nice Guy: Similar like Ryu, most of his arcade win quotes show his sympathy for his opponents.
  • Quest for Identity: "Someone out there must know something about me. I've got to find them!"
  • Protagonist Without A Past: He suffers from amnesia.
  • Religious and Mythological Theme Naming: After Abel, the second son of Adam and Eve.
  • Spear Counterpart: Of Cammy, arguably. They're both young, amnesiac clones of the Big Bad of the game they first appeared in, and both enter the tournament in order to find out who they really are. They're also both blond with light blue eyes, and also share a scarred face. However Cammy prefer cats while Abel chooses dogs.
  • Uh-Oh Eyes: His eyes briefly turn black during his Soulless Ultra, hinting at his connection to Seth.
  • Unnecessary Combat Roll: Abel incorporates the Marseilles Roll, a rolling maneuver, in his fighting style. Although, this move is actually effective when it comes to closing the distance on projectile-spamming foes, or dodging attacks, so it's actually a necessary combat roll.
  • Younger Than They Look: Possibly as an homage to K' from The King of Fighters, who looks like he's in his 20s but is actually 16.

    El Fuerte — Mexico 
"In the ring or in the kitchen, no one can beat me!"

Voiced by: Daisuke Ono (Street Fighter IV; Japanese), JB Blanc (Street Fighter IV; English)

A luchador/aspiring chef. He enters the tournament to find the perfect recipe for his new delicacy. El Fuerte is an old friend of T.Hawk.

  • Captain Ersatz: Bears some resemblance to mexican luchador Mistico.
  • Chef of Iron: Type 1. He enters the tournament to find new recipe ideas.
  • Confusion Fu: El Fuerte has a normal move called Habanero Dash, where he runs towards you. Doesn't sound that bad, no? Well, this move has six different followup moves: evasive actions, high attacks, low attacks, air attacks, and throws. Given that they all start with that running animation, you might be realizing the big picture about now.
  • Cool Mask/Masked Luchador
  • Cordon Bleugh Chef: The opinions on his cooking are mixed throughout the series, but his ending is another story: He mixes Chanko stew and Borscht, Honda and Zangief's favorite national foods, trying to quell the argument between them as to whose dish is better. One bite and they're both blue in the face.
  • Fanboy: Of Rainbow Mika.
  • Fighting Clown: He's a lethal chef with no concept of good cooking (and that is sadly what drives his motivation to fight). He's got ludicrous premises, hammy voice actors, comical-looking attacks with silly food-themed names — it's difficult to take him seriously. But he also has a level of mobility second only to Vega, an unpredictable array of attacks, rapid aerial defense, and high comboability. In the right hands, he's got quite a lot going for him.
  • Fragile Speedster: A first for the series, as nearly all wrestling-themed characters are of the Mighty Glacier type.
  • Forgotten Childhood Friend: He only remembered his childhood friendship with T. Hawk after an insult-sparked brawl.
  • Frying Pan of Doom: Averted. He's shown wielding one in his fight intro, but he doesn't use it in battle.
  • Gratuitous English: In Japanese, he randomly shouts out English, despite being Mexican.
    • Makes sense, considering who his seiyuu is.
    • Gratuitous Spanish: In T. Hawk's rival match with him, El Fuerte drops an audible "amigo" in his opening line. El Fuerte's English VA, J.B. Blanc, adds a few more Spanish words to his dialogue. He even refers to Zangief (during their rival fight) by using the Spanish translation of Zangief's own Red Baron moniker: "Tornado Rojo."
  • Incoming Ham: See catchphrase, and his intro cinematic Big "OMG!" — over meal preparation.
  • Lethal Chef: Figuratively and literally. Chanko Stew + Borscht + a pinch of Chili Pepper = The taste that will send you straight to heaven.
    • His ending in SSFIV has his cooking assistants flat out asking if he really knows what the heck he's doing.
    • Subverted slightly, as he is very good at making Mexican dishes, but is played straight when he tries to cook anything else.
  • Loony Fan: Of R. Mika. In the UDON comics, when T. Hawk says R. Mika looks ridiculous, El Fuerte feels he has no choice but to start a fight over it.
  • Meaningful Name: "El Fuerte" is Spanish for "The Strong One."
  • Red Baron: "The Hurricane of the Gulf of Mexico."
  • Shout-Out: The El Fuerte Ultra Spark. The finishing hold looks very much like the Muscle Spark.
  • Theme Naming: His attacks are named after Mexican food.
  • Walking Shirtless Scene: Justified. He is a luchador.
  • Wall Jumper: Another one in this game.

    Rufus — USA 
Voiced by: Wataru Hatano (Street Fighter IV, Street Fighter X Tekken; Japanese), Christopher Corey Smith (Street Fighter IV, Street Fighter X Tekken; English [as Chris Kent])
Candy voiced by: ? (Street Fighter IV; Japanese), Laura Bailey (Street Fighter IV; English)

A morbidly obese man who wants to fight Ken to prove that he is the number one fighter in the USA. He's a very talkative person and usually doesn't stop to talk. He has a beautiful girlfriend called Candy, who was once rescued by Rufus when they first met. Aside from his pride in his fighting abilities, he's also proud of his motorbike.

  • Acrofatic: It says something that Rufus has one of the highest jump arcs in the game. In addition, he is capable of cartwheels, pirouettes and Rapid-Fire Fisticuffs.
  • Arrogant Kung-Fu Guy: "You just can't compare!"
  • Big Eater
  • Big Fun: A fat guy who is more a Plucky Comic Relief than a serious fighter.
  • Brilliant but Lazy: Several characters comment on how surprisingly strong Rufus is, and fathom how powerful he could be if he just lost weight.
    • He is also apparently knowledgeable about the finer points of the rules of Sumo. Enough that he is capable of pointing out to E. Honda that what E. Honda now fights with isn't really sumo wrestling at all.
  • Cloudcuckoolander: Some of his rants are really random, to say the least.
  • The Cloudcuckoolander Was Right: Though some of his winquotes are actually true. The most obvious one might be the winquote against E. Honda, when Rufus notes that fighting outsiders outside of the ring is illegal for Sumo fighters.
  • Crouching Moron, Hidden Badass: A big moron, but a very skilled fighter.
  • Eagleland: Very much Type 2: he's loud, obnoxious, dumb, clinically obese, and obsessed with sci-fi.
  • Fat Idiot: Really fat. Really dumb (though, he has smart moments).
    • It says really something that Zangief looks smart in comparison to him when they team up in Street Fighter X Tekken.
  • Fighting Clown: He's considered one of the best characters in the game, and in Super Street Fighter IV: Arcade Edition (Version 2012), Rufus is (still) a top pick for tournaments.
  • Girlish Pigtails: In his alternate costume, whereas his normal outfit displays a single one.
  • Gonk: He's intended to be ugly and disgusting to create a shock factor for the players, which should make him memorable.
  • Hard Work Hardly Works: Subverted. At first glance, it looks like Rufus came up with his elaborate fighting techniques simply by watching kung-fu movies and eating like a pig. However, it's revealed that in order to refine his Kung Food, Rufus took on correspondence courses and later went to China to study under various masters.
  • Hot-Blooded
  • Huge Guy, Tiny Girl: Him and his girlfriend Candy.
  • I Know Mortal Kombat: The crux of his fighting style, as it is wholly based on things that he gleaned from watching martial arts flicks in his youth. Gets some credit because he traveled the world in order to sort out the reality from the fiction.
  • Incoming Ham: The moment you see him fly onto the screen, you had better brace yourself.
  • Jiggle Physics: His belly.
  • Lampshade Hanging: Some of his quotes has him do this to certain characters, such as Chun-Li's hips or asking Seth what it's like being a robot.
  • Large Ham
  • Lightning Bruiser: He seems to be quite similar to Tekken 6's Bob as an incredibly agile fat guy. Hilariously, Bob is his rival in Street Fighter X Tekken.
  • Motor Mouth: He does not only talk a lot, he talks fast as weell.
  • The Munchausen: Rants a lot in his winning quotes. Toned down in Street Fighter X Tekken, where his win quotes are regular-sized, but some of them still look like he'll go on droning.
  • Oh, Crap: He says this upon being KO'd.
  • Rapid-Fire Fisticuffs: His Snake Strike.
  • Rescue Romance: How Candy became his girl, as implied in his exchange with Rose:
    "I'll never forget when I first met my girl. It was a rainy day in October and I was on my way home from a fight. Suddenly, this chick came outta an' was all like 'Help!' I guess she pulled a dine an' dash, so I beat up the waiter that was chasin' after her!"
  • Seinfeldian Conversation: Many players has read his win quotes (yes, it is possible) and thought, "What the heck is he talking about?" Check them.
    • Averted in SSFIV. He actually does stay on topic better, even if he goes off from time to time.
  • Shown Their Work: An in-universe example. Rufus watches a lot of movies, and when he wanted to become a fighter, he traveled around the world to confirm which techniques in movies can or cannot be performed, in the process becoming a formidable fighter that is very, very easy to underestimate.
  • Spin Attack:
    • His Galactic Tornado.
    • Messiah Kick begins with a series of mid-air spins. More visible in the EX version where his spinning actually causes hits.
    • His second Ultra from SSFIV, Big Bang Tornado, is also this, mixed with Snake Strike and brought Up to Eleven.
  • Stout Strength
  • Ugly Guy, Hot Girlfriend: Rufus' girlfriend is a hot little number named Candy who thinks he's super awesome. Doubles as a Huge Guy, Tiny Girl couple.
  • Unknown Rival: Inverse example. He counts himself as Ken's rival, but doesn't know who Ken actually is, and mistakes every blond character for him. Then played straight, as Ken has no knowledge of his existence prior to their match.
    • He mistakes Cammy for Ken, because of her hair color. Even besides the no pants, different appearance, and being female thing, you'd think he'd keep both hair color and length in mind.
    • He mistakes Makoto for Ken, because she uses a gi and goes barefoot. Try and top that.
    • This even goes beyond universe - in one of the trailers for Street Fighter X Tekken, he mistakes Bob for Ken, because he is blonde and wears red. It gets even more amusing when he goes flying past Ken himself later on in the trailer.
      • It only gets worse there. He also mistakes Steve, Paul, JACK-X, Lili, Nina and King for Ken. That's right. He mistakes a guy whose entire head is covered in a jaguar mask for Ken. We can't tell if this is more absurd than the two preceding examples (a French girl and an Irish woman) or not.
    • Then, in Ultra, he goes on to mistake Decapre and Poison for Ken. Nothing more needs to be said.
  • Unreliable Voice Over: He narrates his long road to becoming such a formidable fighter in the UDON comics... except when he talks about his tireless effort we see him watching TV late at night and eating like a pig. Though it's subverted when we're shown him jogging with two motorcycles strapped to his back.
  • Would Hurt a Child: Though he's not too fond of doing so.
    "I don't get my jollies beatin' up on schoolkids, alright? This is a tournament an' I was just followin' the rules is all."

    Gouken — Japan 
"No illusion is safe when bathed in the pure light of the moon. Now is the time to test your strength!"

Voiced by: Tōru Ōkawa (Street Fighter IV; Japanese), Rod Clarke (Street Fighter IV; English)

Gouken is the master of Ryu and Ken and Akuma's older brother; he trained with Akuma under Goutetsu until Akuma killed their master in a Duel to the Death. Gouken refined the special techniques from the assassination art taught to him by Master Goutetsu into a non-lethal martial art, then passed on his knowledge to Ryu and Ken. He was believed to be dead, but he managed to survive his battle with Akuma by using the Power of Nothingness — which empties the mind and soul of all thought and sin — to render the Shun Goku Satsu useless. As a side effect, however, he was rendered unconscious for several years. Gouken now hopes to reunite with his pupils and test their strength.

  • Ascended Meme/Defictionalization: From the infamous EGM "Sheng Long" April Fools' joke. He even has all of the moves (in one way or another) that the joke detailed!
    • One of his win quotes:
    "You must defeat me to stand a chance!"
  • Badass: In his backstory managed to beat Akuma in the first fight, and when they fought again he had resort to the Shun Goku Satsu to win.
    • Badass Beard
    • Badass Boast: "I may be old, but my time is far from over."
    • Badass Grandpa: Never mind that he's the sagacious old man who taught Ryu and Ken how to fight, he canonically defeated Akuma prior to the first game (although Akuma would seemingly pay him back in a second duel, one which ended with the infamous Shun Goku Satsu). And when he comes back to settle the score, he manages to momentarily one-up his brother again by shrugging off the SGS.
  • Big Good: The closest thing the series has to one. Being extremely wise, powerful, and benevolent certainly helps. And unlike most of the other protagonists who could fill the role, he is actively aiming to snuff out evil.
  • Bonus Boss: You mustn't lose any round before defeating Seth, you need to Perfects, ten first attacks and five Super or Ultra finishers, but do not finish Seth of with a Super/Ultra.
  • Cain and Abel: The Abel to Akuma's Cain. And Akuma nearly killed him.
  • Canon Immigrant: First appeared in a Street Fighter II manga before appearing in Akuma's ending the first Alpha and as a hidden challenger in IV. Before that, Ryu and Ken's master was just a nameless unseen character.
  • Convenient Coma: One that lasted years.
  • Cool Old Guy: An old man who not only trained Ryu and Ken, but also survived the Shun Goku Satsu is really a cool guy.
  • Counter Attack: His Kongoshin ("Diamond Body") will stop any non-armor breaking attack (in the right direction), then he simply stomps and sends his opponent flying across the screen. "It's no use!" indeed.
  • Crippling Overspecialization: Unlike most other practitioners of Ansatsuken, Gouken only has the Shoryuken available to him as Super and Ultra combos. Assassin's Fist may give a story explanation for this oddity; while training Ken and Ryu, Gouken demonstrates each of the three principle techniques of his own variety of Ansatsuken, with a fairly average Hadouken and Tatsumaki Senpukyaku. However, when he demonstrates the Shoryuken, he performs it with such skill that Ryu and Ken are left in awe. Presumably Gouken spent so much time trying to remove the Satsui no Hado from the Shoryuken that he managed to devise two incredibly powerful forms: the Forbidden and Shin Shoryuken, his Super and Ultra combos. Gouken probably decided to use these "purer" forms of the Shoryuken, while abandoning their more violent and basic variations.
  • Dead All Along: In the Japanese dialogue in SSFIV, it's heavily implied that Gouken did die shortly after Akuma attacked him, and that his appearance in the game is actually his spirit. Traces of this were removed from the translations however.
  • Defeat Means Playable: In Street Fighter IV. Starts as playable in SSFIV.
  • Deus ex Machina: The Power of Nothingness (or Mu no Ken in Japanese), a technique never spoken of before IV, is the reason behind Gouken's survival of the Shun Goku Satsu and subsequent coma, as well as how he purges Ryu of the Satsui no Hadou. Perhaps Gouken was Holding Back the Phlebotinum.
  • Does Not Like Shoes: Like his disciples, he goes around barefooted.
  • Good Counterpart: To Akuma.
  • Fatal Flaw: Compassion. He refuses to kill his brother Akuma both times he defeats him, which comes back to bite him in the form of a ten year long coma.
  • Flash Step: Gouken's answer to his brother's Ashura Senku was to weaponize it in the form of the Senkugoshoha (Flashing Air Piercing Wave). When executed, Gouken rushes forward, ignoring attacks, and strikes his opponent with the flat of his palm so hard they go flying, depending on the variation used sometimes high enough to land another Senkugoshoha afterwards.
  • Good Powers, Good People: Gouken's branch of Ansatsuken relies on the Power of Nothingness, essentially the pure counterpart of the Satsui no Hado.
  • Hero Ball: Refusing to kill Akuma, even after Akuma makes it clear, on multiple occasions, that he has no qualms about killing Gouken if he ever defeats him. This compunction, however, gets dropped should Oni manifest.
  • Hurricane Kick: A particularly awesome rising variation called the Tatsumaki Gorasen.
  • I Have No Son: His win quote to Evil Ryu.
    "You are no pupil of mine."
  • If You Kill Him, You Will Be Just Like Him: Why he refuses to kill Akuma, despite defeating him twice.
  • Its Pronounced Tropay: Exclusive to his japanese VA; Gouken is the only Ansatsuken practitioner to emphasize the "ken" in Shoryuken, while every other practitioner emphasizes the "Shoryu".
  • Kamehame Hadoken: Has a chargeable, angle-able variant.
  • Martial Pacifist
  • Meaningful Name: Gouken (豪拳) means "strong fist."
  • Nice Hat: A huge-ass one in one of his alternate costumes.
  • No Sell: In Akuma's ending of the base version of IV, the State of Nothingness allows him to do this to Shun Goku Satsu.
  • Not Quite Dead: This seems to be the explanation for him appearing in IV.
  • The Obi-Wan: He has been this to Ryu and Ken, until Street Fighter IV...
  • Old Master: Of Ryu and Ken, no less.
  • Out-of-Character Moment: Doubles as OOC Is Serious Business; After defeating Oni, Gouken has nothing disparaging to say, only "Goodbye, brother." seemingly implying that Gouken kills Oni.
  • Parental Substitute: To Ryu, his adopted son. He's also something of a second father to Ken.
  • Passing the Torch: Gouken knows he won't live forever, and entrusts Ken and Ryu to continue the legacy of Ansatsuken once he passes.
  • Physical God: Downplayed compared to Oni, but Gouken, after having just recently awakened from an almost ten year coma comes to blows with Akuma, and not only nullifies the Shun Goku Satsu but, judging by the fact that Ryu is still alive, defeats Akuma as well. He is also one of the few characters who, in story, has a solid fighting chance against Oni.
  • Religious Bruiser: According to the comics, he is a devout Shintoist. He even has a shrine to Goutetsu in his dojo. Assassin's Fist, however, mentions him as a Mahayana Buddhist. The two are not mutually exclusive, so he may just practice both.
  • Restrained Revenge: Refuses to kill Akuma for fear of becoming just like him. He settles for humiliating him in battle.
  • The Rival: Ryu and Akuma.
  • Sealed Good in a Can: Spent a decade, give or take a couple years, in a coma.
  • Shirtless Scene: He has a shirtless alternate outfit.
  • Shoryuken: Although he only uses it as a Super/Ultra.
  • Shotoclone: Surprisingly subverted. Despite Gouken is Gouki/Akuma's brother and is Ryu and Ken's master, Gouken's fighting style is very different from all shoto characters. He doesn't have a Shoryuken as a basic special move, his Hurricane Kick works different than the typical Tatsumaki Senpuukyaku, and the angles of the Hadouken, which he can fire with one hand, depends on the punch button that is pushed.
  • Stroke the Beard: In his opening and victory animations.
  • Take That: To his own brother, no less; "Neither man nor demon. You are but a deluded fool, Akuma! Nothing more!"
  • Thou Shalt Not Kill: Gouken despises killing so much that he formed an entirely new branch of Ansatsuken just to tone down the lethality of the art.
  • Tough Love: Raised Ryu and Ken with a mixture of this and honest compassion.
  • Triumphant Reprise: His theme is a more lively and heroic version of Akuma's.
  • True Final Boss: His role so far in the two SFIV games released so far.
  • Warrior Therapist: A textbook example; Gouken is old, supremely powerful, and a font of wisdom for younger fighters. Gouken even tries to instill wisdom and goodness into people like Seth and Bison.
    to Dee Jay - "Quiet your heart and truly listen, and you will be surprised at what you hear."
    to Cody "Rethink what you are doing, young one. You cannot run from yourself forever."
  • What Happened to the Mouse?: Earlier sources during both II and Alpha mentioned the existence of a daughter (nicknamed "Ojou-san") who witnessed Gouken's death at the hands of Akuma, was hopelessly smitten with Ryu, and provided him with the white headband he wore until II.
  • World's Best Warrior: Even at 60+ years old, he can still hand fighters like Akuma their asses with very little effort.
  • Worthy Opponent: Sagat. Apparently, Gouken has wanted to face him for years.
  • X-Ray Sparks: His Denjin Hadouken in Super IV has this effect. Note that Ryu could use the exact same technique in 3rd Strike, and had the same electrifying effect on the opponent.

    Seth — S.I.N 
"Do not grieve. Your data will reside in me for eternity."

Voiced by: Akio Ohtsuka (Street Fighter IV, Project X Zone; Japanese), Michael McConnohie (Street Fighter IV; English'')

Seth is the CEO of S.I.N, the (former) weapons division of Shadaloo. Seth modified his own body to include a S.I.N invention known as the Tanden Engine; the device is used to help Seth assimilate the abilities of anyone he fights. Seth also created the BLECE Project, which relies on ki to create super-soldiers (in this case, the Ki Seth uses is the Satsui no Hadou); he sees Ryu as the "ultimate test subject" and desires his untapped Satsui no Hadou to complete the BLECE project. Seth has another goal in mind, as well: surpassing his creator, M. Bison, before destroying him once and for all.

Debuting in Super Street Fighter IV

    Juri — South Korea 
"Hmm... You look like you're in good shape..."

Voiced by: Eri Kitamura (Super Street Fighter IV, Street Fighter X Tekken, Project X Zone; Japanese), Jessica Straus (Super Street Fighter IV, Street Fighter X Tekken; English)

Her full name is Juri Han, and her codename is "Spider"; she is a Taekwondo prodigy from South Korea who serves as an agent of S.I.N. She is testing out one of S.I.N's most advanced pieces of technology: a cybernetic eye implant known as the Feng Shui Engine. The implant, which a smaller version of Seth's Tanden Engine, takes ki energy from the surrounding nature and feeds it to the Engine's user to heighten their abilities and make them more powerful. Juri pledges loyalty to Seth in exchange for the "new toy", then enters the new Street Fighter tournament to test her new abilities... and further her own dark agendas. Juri is a dangerous, hedonistic sociopath who likes to taunt her opponents — and she doesn't care about anything but satisfying her dangerous whims.

  • Absolute Cleavage: Her second alternate outfit.
  • Abusive Parents: Her mother at least. In the comics, she berates Juri when she messes up during Taekwondo practice. Her father, though strict, is more caring as he is visibly distraught when she is shot in the left eye.
  • Affirmative Action Girl: Part of the reason she was created was to fill two voids: a proper female villain and a Korean character. In her villainous role's case, while Cammy was a vilalin during the Street Fighter Alpha days, it was because she was brainwashed into being Bison's assassins Killer Bee, while Juri is straight-up FUCKING. EVIL. In her ethnicity's case, she is Capcom's first Korean character ever.
  • Amazonian Beauty: Chun-Li = legs; Juri = abs and arms.
  • Animal Motifs: Insects, especially spiders and butterflies.
  • Anime Hair: She sports hair-horns.
  • Arachnid Appearance and Attire: The backside of her outfit has a spider net motif. Also, the front of it has a spider insignia on it.
  • Arch-Enemy: To Cammy. Not so much to Chun-Li as she sees her as another distraction at best.
  • Ax-Crazy: Oh yes. Being a Depraved Bisexual with unabashed sadism, Juri is basically an untamed animal when left to her own devices.
  • Badass: Yes, the girl needs to be locked in a rubber room and pumped with enough drugs to tranquilize a tiger, but given that she managed to defeat Chun-Li, Guile, and Cammy in straight-up fights during her OVA, she's undeniably a badass.
    • Empowered Badass Normal: Her powers come from the Feng Shui Engine in her eye, but even without it, her Taekwondo skills make her a deadly force to be reckoned with.
  • Bare Your Midriff: Her default costume, her first alternate costume, and Ultra Street Fighter IV's Summer Costume.
  • Big "NO!": In her Game Over animation.
    • Seeing how she covers her eye, it looks more like a Skyward Scream of agony.
  • Blood Knight: Derives an almost erotic pleasure from fighting and killing.
  • Card Carrying Villainess: She knows she's evil and relishes every second of it. In fact, she'll tell you herself. She loves killing people.
  • Casting a Shadow: Her Ki Attacks are a dark purple.
  • Cat Girl: The buns in her hair and the sash on her waist gives her the appearance of one. Not to mention her amazing flexibility.
  • Character Tics: Her tendency to lick her lips and her weird and unsettling facial expressions.
  • Code Name: "Spider".
  • Combat Sadomasochist Whether it's getting hurt or giving hurt, it's all fair game to Juri.
  • Combat Stilettos: In her alternate costumes.
  • Continuity Nod: Her Shikusen special can be linked for 3 hits; the second hit is called "Second Impact" and the third is named "Third Strike."
  • Curb-Stomp Battle: Dishes these out with alarming regularity in her OVA. See One-Woman Army below.
  • Cyborg: Thanks to the bionic eye and all.
  • Dark Action Girl: The most straight-up example here.
  • Dark and Troubled Past: Juri's father was a fearsome prosecutor who relentlessly pursued people connected to Shadaloo to bring them to justice. He became Shadaloo's target and one day Juri's family car was sabotaged. Her father and mother died and she was severely injured, losing her left eye.
  • A Day in the Limelight: Her OVA.
  • Deadpan Snarker: Has her moments.
  • Depraved Bisexual: Her opponent's gender makes no difference to her as long as she gets to torture them.
  • Disability Superpower/Artificial Eye: Seen below.
  • Distaff Evil Expy: Could be seen as one to Kim Kaphwan and Jhun Hoon.
  • Does Not Like Shoes: Subverted with her alternate costumes, where she dons Combat Stilettos, otherwise she's either completely barefoot or wearing Taekwondo straps.
  • Double Entendre: Practically 90% of her dialogue is this. She can't seem to form a sentence without making some kind of sexual innuendo.
  • The Dragon: For Seth.
  • Dragon Lady: A Korean villainess with Asian looking attire.
  • Energy Ball: Like many characters in the series, Juri is able to throw projectiles. Unlike any characters in the series, she throws them with her feet.
  • Establishing Character Moment: After recieving the Feng Shui Engine in her OVA, the first words she says tell you all you need to know about her.
    Juri: "So... let's go kill something."
  • Even Evil Has Standards: In her OVA, Juri seems to hesitate when her only remaining possible victim (before Chun-Li rushes onto the scene) is a young child crying over his dead mother whose casualty was an unintended outcome of Juri's Feng Shui Engine test run. This likely stems back to Juri's own tragic backstory. Furthermore, it's stated on multiple occasions that even she has nothing but hatred for Shadaloo.
  • Evil Counterpart: She appears to be one to both Chun-Li and Cammy.
  • Evil Laugh: Happens a lot.
  • Evil Tastes Good: Licking her lips is practically her Catch Phrase. It's also the sign she's going to beat you within an inch of your life.
  • Extremity Extremist: Averted. She, despite being a Taekwondo practictioner, uses punches. However, she's still a Kick Chick, more or less.
    • She only has medium and light punches. Her hard "punches" are kick attacks.
  • Eyepatch of Power: Wears one temporarily in the SSFIV OVA, after her left eye malfunctions as she's about to kill Chun-Li. Also wears one in the UDON comics.
  • Eye Scream: The UDON comics reveal she was shot in the left eye during Shadaloo's assassination attempt on her father.
  • Fan Disservice: Mostly an In-Universe example as Poison flat out calls her this, what with the Ax-Crazy attitude.
  • Faux Affably Evil: Makes no excuses for who she is and her crazy behavior.
  • Flash Step: Her Kasatushi. Juri makes a teasing gesture and if her opponent hits her, she dashes to a different location depending on which punch button is pressed. However, this will not work with throws or attacks that break armor.
  • For the Evulz: She joined S.I.N. for fun and it's pretty much her raison d'tere for everything she does.
  • Freudian Excuse: Downplayed. Her parents were killed by Shadaloo. Juri, however, doesn't seem to particularly care too much.
  • Getting Crap Past the Radar: She's practically the virtual embodiment of this trope for the series.
  • Glass Cannon: She's a fast character, and unlike Chun-Li or Cammy, Juri does not lack strength. But like most female characters, her health is below average.
  • Glowing Eyes of Doom: When her left eye's glowing, that's a dangerous sign.
  • Gone Horribly Right: Seth plans on offing her if she becomes too successful.
  • Gratuitous Japanese: Her English voice has some random Japanese words.
  • Hannibal Lecture: Delivers one to Cammy, evoking Not So Different and calling her out for thinking that her brainwashing will allow her to avoid responsibilities for her actions as an agent of Shadaloo. Cammy doesn't give a Shut Up, Hannibal!, but there is a pretty fierce Death Glare directed at Juri.
  • The Hedonist: She outright says that as long as she's having fun, she's happy. Too bad her idea of "fun" involves people getting hurt.
  • Horned Hairdo: Her hair is tied to resemble this.
  • Hypocrite: Calls out Cammy for her "sins" despite doing nothing but evil deeds herself.
  • Interplay of Sex and Violence: For Juri, Sex Is Violence.
  • Jerkass: Easily one of the most violent, sadistic, psychopathic, and flat out unpleasant characters in the series next to Bison and Vega, a stark contrast to Cammy and Chun-Li. She only seems to show begrudging respect to those who can put up a good fight, but even then that offers no protection from her sadism. Her dislike of hurting children and her hatred of Shadaloo (see Even Evil Has Standards) seem to be the only real redeemable traits she has.
  • Kick Chick: Probably even moreso than Chun-Li, to the point that her "heavy punch" is in fact a kick.
  • Lack of Empathy: Juri cares only for herself. Everything else is either a toy or an insect as far as she's concerned.
  • Laughing Mad: Whenever she's beating the stuffing out of someone.
  • Lean and Mean: Though not without some muscle.
  • Magitek: More like "Kitek", but, hey, technicalities.
  • Ms. Fanservice: Possibly the biggest one (after Poison, of course) in the series, not helped by her revealing costumes and seductive personality.
  • Obviously Evil: At no point can this girl pass for a good guy with her violent sadism.
  • One-Woman Army: In her OVA, a bunch of armed soldiers, Chun-Li, Bison's elite guard, Guile, and Cammy are no match for her.
  • Orgasmic Combat: Tends to let out some pretty erotic moans during combat.
  • Parental Abandonment: Thanks to Shadaloo.
  • Person of Mass Destruction: Want proof? Look at her OVA. She manages to completely destroy an amusement park and kill everyone in there save for one person using the Feng Shui Engine. Keep in mind that she was using a prototype at the time.
  • Photographic Memory: Claims to have this.
  • Power High: After gaining Ki-based powers from the Feng-Shui Engine she proclaims, "Mmm... I like it. I can feel waves of ki energy surging through my whole body," in a very suggestive way.
  • Psychotic Smirk: Her default expression.
    • Slasher Smile: Upgrades into this if she's particularly enjoying torturing someone.
  • Purple Eyes: They reflect that she has superpowers. It helps that one of them is cybernetic and gives her those powers.
  • Purple Is Powerful: Her eyes, clothing, and special moves are colored purple and she's quite strong.
  • Put the "Laughter" in "Slaughter": If you hear her laughing hysterically, it usually means someone's getting beaten up.
  • Rapunzel Hair: Though it's normally tied up in a Horned Hairdo. Her summer costume in USFIV has her letting it all hang out.
  • Revenge: Against Bison and Shadaloo for killing her parents.
  • Sadist: She really gets off on hurting others.
  • Sexy Backless Outfit: Doesn't help that the straps of her shirt look more like a tattoo than clothing material.
  • Sexy Walk: Her normal walk looks like this.
  • The Sociopath: Simply put, Juri does what Juri wants. And if people get hurt, she's cool with it.
  • Straw Nihilist: Has shades of this. Shown in this exchange between her and Chun-Li in the OVA.
    Chun-Li: "All the innocent lives you destroyed!"
    Juri: "Give me a break, sweetie. There's no such thing as innocent. It must suck to be so stupid."
    • And also in one of her win quotes in Versus Mode.
    Juri: "Learn to fight like me, and you'll realize how boring everything else is."
  • Stripperiffic: All of her costumes.
  • This Cannot Be!: In Japanese, she says "Sonna bakana!" when K.O.'ed. Translated, it'd be along the lines of "I can't believe it!"
    • In English, however, it's "I'll have my revenge!" If you K.O. with a light punch, light kick or Focus Attack so that she K.O.s in a crumple state though, she still says "I can't believe this..."
  • Too Kinky to Torture: She enjoys receiving pain as much as she enjoys giving it, particularly if she's fighting strong opponents.
  • Turned Against Their Masters: In her ending, she used Seth's tournament as a distraction while she plotted to take over S.I.N.
    • But the reverse happens in Seth's ending, as she decided to follow him because of the fun she's having.
  • Used to Be a Sweet Kid: The UDON comic gives an insight into Juri's backstory and shows was once a kind, innocent, and somewhat reserved girl who wanted to make her strict, but loving parents proud, a far cry from hedonistic, sociopathic sadist she is today. It took Shadaloo murdering her parents to turn her into cold-blooded killer obsessed with becoming a pure embodiment of death. Compare this image of her as a kid to this image of her now and it's quite jarring to see the difference.
  • Vapor Wear: Her second alternate costume.
  • Whole Costume Reference: Jolyne Cujoh from JoJo's Bizarre Adventure
  • Worthy Opponent: Has shades of this with Ryu, Ken, Akuma and Oni as their the only fighters in the game that she does not have resounding contempt for.

    Hakan — Turkey 
"Looks like it's time to oil up!"

Voiced by: Shintarou Oohata (Super Street Fighter IV; Japanese), Lance Holt (Super Street Fighter IV; English)

The other new character introduced in Super Street Fighter IV line-up. He is stated to be the Turkish CEO of a cooking oil company, and a practitioner of the national sport of Yagli Gures otherwise known as oil-wrestling. His in-game self reflects this with lots of oiled-up grappling and even a move that has him apply more oil to his body, powering up his moves for a short time and making him faster.

  • Absurdly Youthful Mother: His wife. She has a fairly petite build, despite having given birth to seven daughters.
  • Amazing Technicolor Population: Tomato red skin, sky blue hair(?).
    • There's an explanation for that: Hakan stays oiled up all the time. Turkey is a sunny place. What does Oil + Sunhine create? At first, a tan. But Hakan did go beyond that. Ken even notes that he "looks a little crisp." The hair is probably blue because he uses oil for that, too and they didn't want to give him black hair.
    • In reference to his hair—the appearance of Hakan's hair is a pun, as he is Turkish and the Japanese word for Turkey is "Toruko", his hair resembles stone and the Japanese word for stone is "Ishi", and his hair color is turquoise and the Japanese word for turquoise is "Toruko Ishi". This holds true for European languages as well: the English word turquoise comes from the Old French turqueise which literally means "Turkish [stone]".
  • Animal Motifs: Both his beltbuckle and the barrel that he uses to "oil up" seems to share the same leonine theme.
  • Anime Hair: His hair is curled into very short ringlets that look like giant barnacles. In one of his taunts, he expresses concern that his opponent will mess it up. His daughters appear to have inherited this style, or at least style it like their father.
  • Badass Mustache
  • Bear Hug: One of his special grabs. (However, because he is slippery, the opponent flies off instead of getting crushed.)
  • Boisterous Bruiser: Very much so.
  • Catch Phrase: "Looks like it's time to oil up!"
  • Cheshire Cat Grin: In his versus silhouette.
  • Chivalrous Pervert: Seems so. While he loves and cares for his wife and daughters, he's rather pleasant to the major part of the Action Girls in the cast (barring Viper and Juri), if his post-battle lines are signs.
  • Cultured Badass: In his own Turkish cultured way, he's pretty refined as well.
  • Doting Parent: Implied in his first line in his character trailer.
    • Confirmed in his ending, when the seven little girls come greet him and Hakan is quite happy to see them.
  • Dumb Muscle: Has shades of this, as shown in his opening or in Seth's rival scene.
  • Everybody Knew Already: Despite Capcom's best efforts to keep him under wraps before his planned debut, he was mentioned as far back as September '09 when details of the game first emerged.
  • Expecting Someone Taller: C. Viper almost says this word-for-word.
  • Fashionable Asymmetry
  • Friend to All Children: He has children himself.
  • Gentle Giant: Though not a bad guy and he's a friendly father, he actually subverts it during his opening, when he attacks a man he mistakes for an industry spy without listening to him.
  • Happily Married: And he's got the multitude of daughters to prove it!
  • Huge Guy, Tiny Girl: Him and his as yet unnamed wife.
  • I Have a Family: A wife and septuplet daughters, to be specific.
  • Lightning Bruiser: He's a giant of a man, and yet all that oil means he moves across the screen like (literally) greased lightning.
  • Monochromatic Eyes: And unlike other characters in IV, he really like those golden eyes.
  • Murderous Thighs
  • Nice Hat: In one of his alternate costumes, he wears a classic turkish Fez.
  • No Indoor Voice: He's not a quiet man.
  • Pre-Asskicking One-Liner: "Looks like it's time to oil up!"
  • Remember the New Guy: Hakan and E. Honda are old friends, to the point where the former casually calls the later "Edmond". SSFIV marks Hakan's debut in the Street Fighter continuity. Also both of their fighting styles are similar.
  • The Rival: Has a Friendly Rivalry with E. Honda. Strangely, Hakan is the second rival of both C. Viper and Seth.
  • Slippery Skid: His oiled-up body allows him slide along the floor into opponents.
  • The Idiot from Ankara: He speaks in Kansai-ben in the Japanese version, despite being Turkish. In the English version, he speaks with a thick Turkish accent instead.
  • There Are No Good Executives: Averted.
  • Theme Naming: Hakan's every single Special, Super or Ultra move has the word "oil" in it. No idea why.
  • Ugly Guy, Hot Wife: His official art, in addition to showing his seven daughters, has a pretty woman in the background that is his wife.
  • You Gotta Have Blue Hair: A rather odd case. Most characters in Street Fighter who are clearly human in appearance run the entire gamut of naturally occurring hair colors. Hakan's is turquoise colored, probably as a result of oils. But when you look at his seven kids, it could be hereditary.

Debuting in Super Street Fighter IV: Arcade Edition

    Oni — ??? 
"I shall grind beneath my heel... all that exists."

Voiced by: Taketora (Super Street Fighter IV: Arcade Edition; Japanese), Dave Mallow (Super Street Fighter IV: Arcade Edition; English)

His full title is Kuruoshiki Oni ("Mad Demon"). This is the form Akuma takes when he reaches the absolute peak of his training; all of Akuma's remaining humanity is consumed in full by the Satsui no Hadou and he becomes a demon, although Oni views himself as transcending gods. Now that he has reached the peak of the Satsui no Hadou, he decides to destroy the world... possibly out of boredom.

  • A God Am I: And take our word for it, disputing this is inadvisable.
  • Amazing Technicolor Population: His skin and hair are blue.
  • Badass Boast: His intro quote, and a large majority of the things he says to those he is about to do battle with certainly qualify, but his Ultra 2 activation quote stands out.
    "My power... MOVES WORLDS!"
  • Barbarian Long Hair: Oni has longer and wilder hair than Akuma.
  • Battle Aura: Oni has a purple one, to be exact. Interestingly, instead of Akuma's Ten kanji(which is burned into Oni's back) it forms an amalgamation of the kanji Kami and Oni, which can mean demon god. Alternatively, it can be read as Kon, meaning Soul.
  • Battle in the Center of the Mind/Enemy Within/Enemy Without/Your Mind Makes It Real: Akuma and Oni's quote for one another confirm that Oni plays this role to Akuma, as Oni represents the one thing Akuma doesn't want to become (luckily, as canon dictates, Akuma being consumed by the Satsui no Hadou will most likely never come to pass, if III is any indication).
    • Rose's winquote against Oni actually raises the rather frightening probability that Oni will come to exist eventually...when Akuma has mastered his most dangerous techniques.
    "Why...I never expected you to appear now.."
  • Beating A Dead Player: The only character in IV to directly interact with the opponent during their win screen pose, Oni grabs his defeated challenger by the head/neck and slams them face-first into the screen, presumably killing them. That last part happens just off-screen, of course.
  • Blood Knight: Both more and less so than Akuma. On the one hand, Oni actually admits to enjoying battles with a much wider variety of fighters than Akuma. On the other hand, he isn't particular about fighting actual fighters and will murder anybody he comes across if the whim strikes him.
  • Bonus Boss: Oni appears as a secret boss by completing Arcade Mode under certain conditions, namely not losing a round, getting two Perfects, five Super or Ultra combo finishes, ten first attacks, and defeating Seth with a Super or Ultra combo.
    • True Final Boss: Oni falls into this, considering he's stronger than Akuma, Gouken, and Evil Ryu combined.
      • Evil Ryu and Oni appear to be rivals of sorts. So it's likely give and take with their power levels. Both are off the charts and by far the most powerful "evil" characters in the cast.
      • SNK Boss: Oni's A.I. is also harder than the aforementioned characters. He has more vitality and stun than the playable version and his moves are altered (for example, all of his chargeable moves are fully charged when he uses them).
      • Although the bonus boss doesn't get nearly as many complaints as Seth does. Evil Ryu is actually easier to abuse due to his ability to cancel his teleport into anything at any time. Capcom has long made the boss characters different than playable characters (Shin Akuma, Shin Bison, etc). Evil Ryu and Oni are seen to be rivals of sorts and are somewhat comparable in power, Super Saiyan Aura and all.
  • Brought to You by the Letter "S": Oni has both the Ten kanji, which is burned into his back, and a personal kanji of his own; Kishin, meaning Demon God.
  • Card-Carrying Villain: He flat-out says that he's evil in his intro.
  • Charged Attack: His Gohadoken. The more it's charged, the farther it goes.
  • Dark Reprise: Oni's theme is a darker, more chilling version of Akuma's theme that retains only a few chords of the original song.
  • Deadpan Snarker: With heavy emphasis on the "dead" as his pre-fight quote against Adon shows.
    "Time to skin this jaguar..."
  • Does Not Like Shoes: Oni loses Akuma's sandals and goes completely barfooted.
  • Early-Bird Cameo: In one of Akuma's SFII endings, he speaks to what identifies itself as the shadow of his soul, that will eventually overwhelm him and drag him into darkness. This is believed to be the first hint of Oni's existence.
  • Evil Sounds Deep: His voice is the same as Akuma's, but distorted even more by Power Echoes. Averted in the English version, where even with the Power Echoes his voice is surprisingly tenor.
  • Fighting from the Inside: The playable version of Oni is being held back by what remains of Akuma in hopes of somebody killing him. Shin Oni manages to shrug off this restraint.
  • Flash Step: An offensive variant; his Rakan Dantojin (Arhat Severing Tower Blade, or Demon Slash) involves Oni suddenly rushing forward and passing through attacks while delivering a strike to his opponents midsection that sends them flying.
  • Flaming Hair: The effect of this look is given.
  • Flat Character: He's evil and... yeah, that's pretty much it.
    • This can be justified in that Akuma's motivations and pursuit of the ultimate fighting technique caused him to tap into something he really shouldn't have. That entity (Oni) doesn't need a lot of characterization because its mere existence is enough to tell you about it.
  • Gameplay and Story Segregation: Regular Akuma is higher on the tier list than Oni is.
    • Although it could be not entirely a lie. Oni seems to be incapable of fully controlling his power like Akuma. We have also seen that he required a lot of effort to do a task (blow up a volcano) that Akuma might do on a bigger scale without much effort.
  • God of Evil: Outright declares himself to be such.
  • Guest Fighter: Oni becomes a Alicorn at one point
  • Glowing Eyes of Doom: Like Akuma.
  • Ground Pound: This happens at the beginning of his Ultra II and his Sekisei Jiraiken special move.
  • Kneel Before Zod: His taunt orders the opponent to do so.
  • Obviously Evil:
    "I am evil incarnate!"
  • Made of Plasticine / Chunky Salsa Rule: One of Oni's alternate costumes has cracks running throughout his body. As he is hit with progressively more damage, his body slowly crumbles away, revealing a swirling mass of dark Ki.
  • Names to Run Away From Really Fast: The fact that his name literally means "Demon" should be enough to get you worried.
  • One-Winged Angel/Superpowered Evil Side: Is this to Akuma.
  • Person of Mass Destruction: Several of Oni's quotes would imply he sees himself as this, as well as how utterly powerful he is.
    "Oni's voice shall be as thunder..." and "Oni shall usher in unimaginable calamity"
  • Physical God: Easily among the top five most powerful characters in the Street Fighter universe, considering normal Akuma pales in comparison to him.
  • Power Echoes: Oni's is heavily distorted.
  • Power Limiter: Word of God is that the playable version of Oni is being held back by remnants of Akuma's will, and that the True Final Boss‎ version of him, "Shin Oni", is not.
  • Power Incontinence: The tiny Soul Fragment of Akuma left inside Oni is wasting and reallocating power in order to allow somebody to kill him. This is presumably why he cannot throw a normal fireball in the air, but can throw airborne Ultra fireballs, and why he cannot perform a true Ashura Senku nor the Kongou Kokuretsuzan.
  • Pre-Asskicking One-Liner: Like Evil Ryu, Oni as a boss character has for each character an individual pre-fight quote.
  • Red Eyes, Take Warning: Like Akuma, he has glowing red eyes.
  • The Rival: His rivalry with Ryu carries over from whatever little part of Akuma is left in him. Oni even seems pleased that Ryu's finally given into the Satsui no Hadou if you face him with Evil Ryu. Oni is also intrigued by the power/potential of certain characters and seeks to test them in a Worthy Opponent-like manner; most notably, Oni remarks that if Cody were to stop voluntarily holding himself back by wearing those handcuffs, he'd prove to be quite the challenge.
  • Say My Name: His Ultra activation quote in his Rival Battle against Gouken has Oni furiously belting out the name of his nemesis at the top of his lungs. Nothing more would probably suffice.
  • Sliding Scale of Villain Threat: Oni is a much larger threat then Akuma ever could, or might desire to be. Whereas Akuma only ever sought strong, individual opponents, Oni seeks murder and destruction on a planetary scale, and, judging from how powerful he is, it's very feasible that he could accomplish just that.
  • Super Mode: During several of his Supers, Oni turns jet black with glowing eyes and hair and Volcanic Veins on his fists and arms.
    • In a way, Oni himself. The transformation from Akuma to Oni isn't a voluntary one, but Oni is several magnitudes more powerful than Akuma.
  • Third-Person Person: Oni speaks this way in some of his winquotes.
  • Walking Shirtless Scene: The upper part of the gi is ripped off.
  • Worthy Opponent:
    • Cody, one of the few people Oni implies can actually stand up to him and stand a good chance of winning.
    • Evil Ryu as well, Who even Oni admits was an obstacle in his path.
    • Perhaps Sagat, for Oni says that he would "enjoy matching wits with him".
    • And possibly Sakura, as he acknowledges that she has come far.
  • You Gotta Have Blue Hair: Like his skin. And his hair glows.

Debuting in Ultra Street Fighter IV

     Decapre — Russia 

Voiced by: Miyuki Sawashiro (Japanese), Caitlin Glass (English)

One of Bison's Dolls. While Juri ended up severely crippling the majority of the Dolls, Bison managed to keep at least one of them still active. Decapre's motives are unclear. She works under Bison's direct orders like the rest of the Dolls, and it is hinted that she is searching for Cammy as one of her targets. She also has memories of the scary childhood of growing up as a lab experiment.

  • Amazonian Beauty: In the same vein as most of the females in the cast. Her Summer Vacation DLC outfit (care of Udon) however emphasizes just how ripped she is even compared to the rest of the cast (even Cammy).
  • Ascended Extra: Her first appearance was in Street Fighter Alpha 3 during the boss fight introduction against Juli and Juni.
  • Ax-Crazy: We're talking Juri levels.
  • Berserk Button: Cammy. To the point where she will attack her on sight regardless of her prior orders or mission objectives. As shown in her ending, when Cammy arrives after she's defeated Seth, she goes from calculated assassin to shrieking madwoman as she attempts to kill her.
    I'll end you! I'll destroy every part of you! KILL YOU!!
  • Blade Below the Shoulder: She has a retractable blade in each of her gauntlets.
  • Brainwashed and Crazy: She's been heavily conditioned from birth to be an assassin and only follow Bison's orders.
  • Canon Immigrant: While she did show up in Alpha that was a palette swap to give some level of difference between the dolls. UDON was the one that gave her more of a backstory which Capcom ran with, so technically her character is more from the comics.
  • Cat Suit: Like the other Dolls, she wears one.
  • Charged Attack: The "Hold" variety like most other characters in the series. She seems to be a Charged Attack version of Cammy.
  • Cool Mask: Has had two different types of metallic mask amongst her appearances, one which covers her face entirely and one which exposes her mouth and nose.
  • Cloning Blues: She's a clone of Cammy, but unlike Cammy, is still under Bison's manipulation. If Capcom takes anything from her character in the Udon comics (as they have done for other characters), then she's actually a failed prototype of Cammy.
  • Clothes Make the Maniac: The black mask on her face is certainly sinister looking, but it's unknown if it serves any combat purposes. In the Udon comics, the left side of her face is horribly burned and scarred.
    • The pre-production art that Capcom released shows that she's scarred here as well, though not as severely as in the comics, which use the Alpha 3 design, wherein Decapre's mask was full-face, so the artists drew the scars going all the way down to her mouth's height; her Ultra mask leaves her mouth exposed while hiding any nasty bits, so her face is only slightly burnt up until the cheek (still on the left side, though).
  • Death Equals Redemption: In her ending, Decapre's body begins to deteriorate. Bison says she only has moments left, but could save her if Cammy worked out an agreement. Even though Decapre swore to kill Cammy until the very end, when she sees Cammy standing over her, ready to defend her from Bison, she tries to comfort Cammy by saying the same words that Cammy said to comfort her when they were children, just before blacking out. She seems to have found some sort of peace in her final moments.
  • A Death in the Limelight: It is strongly implied that she dies in her ending, as she has already begun to deteriorate. Bison says there is a way to save her, and knowing how often he's cheated death, it wouldn't be out of the question for her to be alive in later games.
  • Dramatic Unmask: We get to see what's underneath the mask in her arcade ending. She's a clone of Cammy, and she's dying.
  • Energy Ball: Her Psycho Stream Ultra fires a large slow-moving one.
  • Flash Step: Has couple of teleporting moves which is accomplished with this.
  • Foil: To Cammy. In a sense, Decapre represents who Cammy would have turned out to be had she not escaped Bison's clutches, and likewise Cammy also represents what Decapre could have been had she only been free of Bison. Their similar design and moveset also purposefully evokes that.
  • Fragile Speedster: Just like Cammy.
  • Knife Nut: Uses claws like Vega, except these ones are retractable.
  • Machine Monotone: If she's not going nuts, her voice is usually monotone.
  • Moveset Clone: Averted, she only retains a couple of special attacks from Cammy, both of which she uses very differently. Her Cannon Drill is not only now a charge move, but it can ony be done in the air (while Cammy can only do hers on the ground). Meanwhile, her Cannon Strike is now a follow up to her new Scramble teleport move (whereas Cammy could do it anytime on jump in).
  • Robo Speak: Due to her being a brainwashed slave of Bison's, much of her dialogue and win quotes are comprised of short, to-the-point words or phrases. More prominent in the Japanese dialogue where she speaks in the quintessential dull monotone.
  • Sexy Backless Outfit: Like the other Dolls, her Cat Suit exposes her back.
  • Temporal Theme Naming: Decapre is Russian for "December", going along with the names of all the other dolls. However, the proper romanization of the Russian word is "Dekabr", not "Decapre" (which is likely just a phonetic spelling), and her name should be properly said "dee-KAH-br", not "de-CAP-ree".
  • Tragic Monster: One of the most tragic characters in the game. She was a clone of Cammy, an innocent little girl brainwashed into psychotic rage and otherwise emotionless obedience, but still retaining flashes of her traumatic childhood of being conditioned and experimented upon.
  • Unexpected Character: Decapre was the fifth and mysterious character for Ultra, and nobody could imagine that she would appear in this game.
  • Wrestler in All of Us: As a Cammy clone, she naturally has her German Suplex and Frankensteiner grabs.

Crossover characters from Final Fight

    Poison — USA 
"Let's have some fun."

Voiced by: Atsuko Tanaka (Third Strike, Street Fighter X Tekken, Ultra Street Fighter IV; Japanese), Karen Strassman (Street Fighter X Tekken, Ultra Street Fighter IV; English)

Poison is an ex-member of the Mad Gear gang, and currently acts as the manager of Hugo Andore. Despite her managerial duties, she herself is a quite a capable fighter. She and Hugo enter the tournament in 3rd Strike to promote their wrestling stable, the Huge Wrestling Army (or H.W.A.).

  • '80s Hair: Bright pink, feathered tresses complete with wide, angular bangs. Justified, in that she made her Final Fight debut in 1989.
  • All Love Is Unrequited: If one of her old Final Fight endings is still canon, she is madly in love with Cody, who has absolutely no positive or negative opinion of her anymore. note 
  • Amazonian Beauty: Like Juri, it's mostly in the abs department.
  • Ascended Extra: She has appeared as a background character in the Alpha games, as well as in Hugo's winposes and endings, but (ignoring Final Fight Revenge) it wasn't until Street Fighter X Tekken that she finally became a playable character. And now, Poison finally makes her true debut into the main Street Fighter series proper, as a brand-new character introduced in Ultra Street Fighter IV. Not bad for someone, who originally was a minor villain.
  • Attractive Bent-Gender: Someone actually put together a documentary about Poison's gender.
    • Potentially averted. Street Fighter director Yoshinori Ono has stated that she has no canon gender anymore, and that it is up to individual fans to decide what they wish to view Poison as.
  • Bare Your Midriff: She wears a very short top.
  • Berserk Button: Gossiping about her failing wrestling venture, as her own wrestlers find out the hard way.
  • Eagleland: A boorish, morally corrupt sex bomb obsessed with making wads of cash? A very fanservicey Type 2.
  • Face of the Band: In-universe, after scouting for talent in Ultra, she manages to talk Rolento, Hugo, Guy, Cody, Ryu, and Ken into forming a KISS-style rock band.
  • Fun Personified: A decidedly sexy kind of fun, but still.
  • Groin Attack: The end of her 2nd Ultra. Ouch.
  • Heel-Face Turn: No longer affiliated with the Mad Gear gang. Moreover, she's 100% done with being a criminal, and has absolutely no intention of going back, as some of her win quotes attest to.
    to Abel: "I can sympathize, but the future is what's important. Not the past." note 
  • Hidden Depths: Seems to have accompanied her growing an actual personality when she migrated to the Street Fighter series. Aside from having an unrequited crush on Cody, She has become a successful professional wrestler, and if her ending is anything to go by, has impressive latent musical talents and enough charisma to lead a very popular band.
  • Lower-Class Lout
  • Ms. Fanservice: She's attractive, she's scantily-clad, the camera makes a great deal out of both, and whilst most characters have movesets based on various real-world martial arts (or some sort of sci-fi/fantasy weirdness), hers is dominatrix-themed.
    • Regardless of her gender, everything she does is pure fanservice. Everything!
  • Nice Hat: Wears a leather-queen cap.
  • Names to Run Away From Really Fast: Poison.
  • Nice Hat/Chained by Fashion
  • Rapunzel Hair: She has really long hair.
  • Rose-Haired Sweetie: Subverted with her personality. The hair color is part of her design as a criminal street fighter (no pun intended) from the 80's.
  • Satellite Character: Roxy, who grew up in the same orphanage as Poison and is typically implied to be one of Poison's closest friends.
  • Sexy Walk: Carried over from X Tekken.
  • She's a Man in Japan: Poison is either a "newhalf" hermaphrodite or a post-op transexual, and Word of God is that there's no official stance as to which is true. The controversy and confusion adds to her popularity which, as of late, is Capcom's intention.
    • Somewhat related, it should be noted that she has 1000 points of health in Ultra, which is generally the well-rounded health amount in Street Fighter. Among some people, this is informally known as "man health" as most females in Capcom fighters have less than that.
  • She's Got Legs: Thanks to her mini shorts and pumps.
  • Shout-Out: One of her special moves looks like a Rising Tackle.
  • Small Role, Big Impact: Actually in the Final Fight series, but since she and Cody are in the SF games as well, this trope does count for Cody's backstory. The corrupt cop Edi. E framed Poison's crimes (street fighting) on Cody that brought him to prison.
  • Stripperific: She sports a miniscule pair of denim daisy-dukes, and a tiny T-shirt that barely covers her boobs.
  • The Tease
  • Who Wears Short Shorts?: Poison wears short shorts.
  • Unexpected Character: Averted in this case, as it was widely speculated that it would be incredibly easy to port her and the other X Tekken newcomers into Street Fighter IV. This is supported by there being quite a lot of desire by the fanbase to have her as a playable character in the first place.
  • Whip It Good: Her signature riding crop returns in all its glory.
  • Wrestler in All of Us: Her back throw is a frankensteiner, and after Love Me Tender can perform a Poison Rama on the foe to boot.
