—Oni (Street Fighter IV series)

Oni ( Oni?, "Ogre"), also known as Kuruoshiki Oni (狂オシキ鬼 Kuruoshiki Oni?, "Mad Ogre"), is a video game character from the Street Fighter series, first appearing in Super Street Fighter IV: Arcade Edition as a hidden boss. This is the form Akuma takes when he has become one with the Satsui no Hado entirely, completely losing any shred of humanity he had remaining.



Oni are lightning-affiliated demons that are mentioned in Shinto religion and Asian mythology, said to be large demons with fangs and horns that once terrorized and pillaged villages and travelers throughout Asia, such as Japan. Shinto considers impurity and pollution as unholy states of being that demons and malevolent spirits are attracted to or even born from.

Though the character's motivations draw much more from Shinto oni, his visual aspects still bear significant resemblance to that of the Buddhist Kongōrikishi (金剛力士?), or Niō (仁王?). Oni's idle stance, with his raised arm and open mouth, is modeled after Misshaku Kongō, the violent protector of the Buddha also known as the Agyo Niō. His design is also evocative of beings such as Fūjin and Raijin, the Shinto gods of wind and thunder respectively, with the latter being an alternate costume for Oni. Oni refers to himself as both a demon (oni) and as a Fierce Deity (kishin), referencing both his Shinto and his Buddhist inspirations.

In-game origin[]

Due to his training and meditation, Akuma may have suppressed some of the darker aspects of the Satsui no Hado, allowing him to control his actions. As Oni, he finally becomes one with the Satsui no Hado, whose power has now managed to completely overtake him. The developers refer to Oni as "Akuma beyond Shin Akuma".[4]

According to Rose's win quote to Oni, it can be presumed that he was meant to show up at a later time, but not during the present day. This gives the implication that Akuma becoming Oni is not a 'what-if' possibility, but Akuma's fate. Akuma's original CFN profile and Street Fighter 6 design bear a considerable resemblance to Oni, primarily with his white hair, and lack of a gi top and sandals.

The mysterious "shadow" that speaks to Akuma in his Super Street Fighter II Turbo Revival ending could be considered the first foreshadowing to Oni. The observation that Akuma makes about the Pandora Oni in Street Fighter X Tekken as a shadow could be a hint that this is the same being that spoke to him in that ending.

As seen in other media appearances (specifically Asura's Wrath and UDON's Super Street Fighter comics), Akuma appears to be able to transform into Oni and phase between those personas at will. Whether he can do this technique in the main games or not canonically is yet to be seen.


Oni appears as a far more muscular and noticeably larger version of Akuma. He has dark blue skin, glowing yellow-red eyes and glowing, spiky shoulder-length hair, fangs and short protrusions on his forehead, resembling growing horns. The top half of his gi has been blown off by the amount of dark ki he emanates, showing off his musculature; the prayer beads that were once around his neck now float about disconnected around his body. He also has claws on his fingers and toes, and no longer wears sandals; his voice also sounds much more demonic, akin to the demons of Asian myths. While Akuma had a blood red aura, Oni possesses a deep blue aura.

When using fierce attacks or powerful physical attacks of any kind, his arms and legs glow a superheated color. While it is difficult to spot, the kanji of "heaven" ( ten?) also appears on his back during the same animations, seemingly having branded itself on his back. In his second alternate costume, his skin shows cracks like old plaster, which progressively fall away as he is hit with Focus Attacks, showing pure, swirling dark energy underneath; he is the only character to possess such a costume.

Most characters do not recognize Oni as a form of Akuma, even Akuma himself (although Oni recognizes Akuma as his former self). In fact, Zangief is the only fighter to notice Oni's increased build mass; however, Zangief fails to notice any other changes (such as the blue skin, aura, etc.). The only character that recognizes Oni as a form of Akuma is Gouken due to his win quote against him in Street Fighter IV.

Oni has discarded his remaining humanity (saying that it is of no use to "evil incarnate"), his identity as Akuma, and his prominent moral code as a warrior; he will fight anyone to the death, regardless of condition, rather than seeking out worthy opponents to fight in a fair match. His presence is such that certain characters even refer to him as a god in their win quotes.

In addition, he now talks in the third person more than usual, although sometimes he will talk in complete sentences. He also retains some of Akuma's personality traits; despite calling himself "evil incarnate", he still shows strong hostility towards villains such as Seth or M. Bison, who Akuma despises for taking "shortcuts" to attain their power. He is also visibly pleased to see Ryu give in to the Satsui no Hado, based on his pre-boss match dialogue with Evil Ryu.

As mentioned above, in Akuma's Street Fighter X Tekken ending, he faces a Pandora version of Oni, which he aptly refers to as "nothing but a shadow, raging against that which casts it"; the Oni that came from Pandora's box was Pandora's energy responding to Akuma's desire for a battle that will cost him his life.


Super Street Fighter IV[]

In his intro, his roar echoes through the night. Instantly after, his presence causes the explosion of a nearby tree and the death of a bird. He then looks up and proclaims that he is "evil incarnate".

In his ending, he stands in the center of a volcano. Then he only jumps up and chops the ground with his hand, resulting in an instant eruption that engulfs him in lava. As the lava explodes out of the volcano, Oni flies out of it unharmed, laughing maniacally and yelling ferociously.

Street Fighter V[]

Oni is referenced by Kage during his talk with Akuma, in one of Akuma's alternate skins, he appears to have cracked skin similar to Oni's alternate skin in Street Fighter lV.


Fighting style[]

Reaching the full extent of the Satsui no Hado to the point of turning into a demon, Oni's style is considered "without"; instead of a concrete martial art style, he relies on unrestrained, graceful movements filled with abandon, embodying that of a terrible destructive force beyond control. The Satsui no Hado also enables him to perform powerful energy attacks as well.


Strategy-wise, Oni is a character who retains the basic characteristics of Akuma, and has many more moves at his disposal which he can use to control the fight. Many of his special moves' EX versions can confuse foes with their surprising speed, and his projectiles can be used to control space, while his midair moves can be used to keep an opponent off-balance.

His high-damage combos and reversal potential, combined with his above-average walk speed, allow players to create massive-pressure situations while remaining mobile and flexible via buffering moves into other attacks. Unfortunately, Oni's below-average stamina and stun and his short-range Focus Attack means that he relies on getting up-close to the opponent to really excel, although he does have more than a few options for traveling across the screen quickly and closing in on his opponent.


Oni's moves are naturally partially borrowed from Akuma (e.g. his heavy punch seems to resemble Akuma's Focus Attack, although Oni performs a spear hand instead of a punch); he still uses the Tatsumaki Zankukyaku, Goshoryuken and Gohadoken, each with heavily altered properties. Other moves have been altered into or replaced by another move entirely; the Shakunetsu Hadoken is replaced with the electric equivalent, Gorai Hadoken. Oni also loses the ability to teleport, which seems to be replaced by the Rakan Dantojin, a vaguely similar slide that follows with a pair of slashing palm swipes. He also possesses a midair palm thrust in lieu of the Zanku Hadoken; the move grants him major midair maneuverability. He also uses the Sekisei Jiraiken, an overhead smash attack similar to the Tenma Shurettou.

Super/Ultra Combos[]

Oni's Shun Goku Satsu is fairly unique within the main series, being the only variant that is also usable in midair; the only other character with such a move is Cyber-Akuma. Several moves give players opportunities to Super Cancel into the Shun Goku Satsu and create potentially unavoidable setups.

His first Ultra Combo, the Meido Gohado, is a projectile that can be used on the ground and in the air, and also has an anti-air variant; if the ground variant hits at close range, it will yield an extra cinematic in which Oni throws another fireball at the opponent for extra damage. His second Ultra Combo, the Tenchi Sokaigen, is a Misogi-like move that follows up a clean hit with a Goshoryuken to the airborne opponent's exposed back; though it has fewer setups, it deals far more damage.

As a boss[]

Oni can also be fought in the arcade mode as a secret boss. The player must not lose a round, get two Perfects, five Super or Ultra Combo finishes, ten first attacks and defeat Seth with a Super or Ultra Combo to fight Oni at his true limits. Like the other secret bosses in the game, the player has only one chance to defeat the boss form of Oni, and if the player wins or loses to the boss Oni, the game ends. The ending of the current player character will then play from there.

He can be considered the true final boss, since the requirements to fight him are the highest of all secret boss characters in the game, appropriate of a character specifically conceived as "beyond Shin Akuma". The difference between the playable version of Oni and "Shin-Oni" is stated by Capcom[citation needed] to be due to the survival of a small part of Akuma's will that is attempting to weaken Oni.

Gameplay-wise, the 'boss' Oni is analogous to the relationship between Akuma and Shin Akuma. While the two version operate similarly on the surface, Shin Oni's frame data is completely different. He has lesser recovery time between attacks, and his special and command attacks have more invincible frames than the playable version. In addition, he floats with his ki rather than walks, allowing him to move around faster, and he also has more stun and stamina.

His Gohadoken is a two-hit projectile that neither needs to be charged nor fizzles out after a certain distance; the EX variant of the Gohadoken lands three hits and inflicts even more damage. Shin Oni's Gorai Hadoken also inflicts slightly more stun than the normal version, making it hard to win a projectile war against him. His Goshoryuken, Rakan Dantojin, and Sekisei Jiraiken have more invincibility at startup (against projectiles and lower body hits respectively), than the regular versions. He also possesses an EX version of the Zanku Hadosho which is unavailable to the playable version.

His regular and air Shun Goku Satsu also travels much faster and farther, are completely immune to any attacks, and have greater priority than most Ultra Combos. The only possible methods to dodge evasions are jumping, Shoryukens and any moves that have startup invincibility; it is impossible to counter boss Oni's Shun Goku Satsu. As an added difficulty spike, the frames needed to activate boss Oni's Tenchi Sokaigen are half that of the regular playable version.

Crossover Appearances[]

Asura's Wrath[]


Asura's Wrath DLC Super Street Fighter Akuma Vs Asura DLC May 15th 2012 lost ep 2

Asura forces Akuma to give into full power of the Dark Hado

Oni appears in the second half of the second DLC Lost Episode The Strongest vs. The Angriest, given the epithet of "Destroyer of Heaven". After being slammed into a wall, the Mantra impowers Akuma immediately as the Satsui no Hado take over his body and transform (showing that he has some semblance of control), which prompts Asura to go into his strongest form possible (and the second strongest form), Mantra Asura. Oni goes toe-to-toe with the wrath-embodied god and starts the battle off with a Misogi.

Much like the Evil Ryu battle, the fight with Oni uses the traditional battle system featured in Asura's Wrath and Oni's attacks are significantly modified for the style of the game which allows for a seemingly more accurate portrayal of his powers, which include: gigantic Gorai Hadokens, a spread version of Gohadoken that fires off five shots, a much larger Tatsumaki Zankukyaku, and the ability to warp when using Focus Attacks. He retains his Ultra Combos, but it is possible to avoid them; Asura also has the ability to redirect the Meido Gohado, and counter the Shun Goku Satsu in a manner similar to his earlier defeat of Evil Ryu, but if Asura does not counter it in time, Oni will be shown attacking Asura with a swinging punch to the side of the head, a punch below the chin, a punch to the face, a punch to the chest, and finally sends Asura flying with the final blow, which deals a lot of damage. Finally, Asura can counter the Tenchi Sokaigen with a similar-looking move before countering the final punch, forming the familiar kanji.

The battle continues until Oni thrusts towards Asura and punches him into the Moon so hard it splits apart, despite Asura blocking the attack. The battle is then taken inside its core and in space. The battle ends when both combatants wrestle each other while blasting through the Earth's atmosphere and crash-land, still struggling; the struggle lasts 500 years, still not ending as they are reduced to their normal forms, and they are now almost statues covered in moss. Both suddenly start to move, as then both fighters throw a punch to each other's faces, ending the episode in a cliffhanger.

Blood Brothers 2[]

Oni appears in DeNA’s mobile RPG, Blood Brothers 2.[5]

Street Fighter × Tekken[]

An alternate form of Oni, made out of the power of Pandora, appears in Akuma's ending.


UDON comics[]

Oni appears in UDON's Super Street Fighter comics; specifically the second volume, Hyper Fighting. During the major fights against the Secret Society, Akuma emerges and throws a Hadoken at Ryu (who had absorbed the Satsui no Hado from Sakura earlier), causing the latter's evil form to emerge, while the former unleashes all his power to transform into Oni; the two powerful forces clash at each other in a epic fight. Soon, Gill arrives and demands that both Oni and Evil Ryu calm down, Oni responds by throwing a Meido Gohado at Gill, who easily counters the projectile with a more powerful ice sphere that freezes Oni, but he breaks free from the ice and attempts to attack the Secret Society's leader again. Gill then throws one fireball at Oni and one ice-sphere at Evil Ryu, and knocks them both down. This defeat causes Oni and Evil Ryu to revert to their respective normal forms.

Oni makes a return in the final two issues of Street Fighter Unlimited. Akuma assumes his Oni form in his ultimate battle with Ryu. After Ryu had obtain balance with both the Satsui no Hado and Power of Nothing from his fight with Gill and became Shin Ryu, Akuma becomes Oni and engages in furious combat. Oni chastises Ryu on following Gouken's and Oro's words on not fully giving into the Satsui no Hado, but Ryu overpowers him with his new found strength. With his power, Ryu overwhelms and defeats Oni forcing him to revert back to Akuma.

Street Fighter vs. Darkstalkers[]

Oni appears in UDON's comic book crossover Street Fighter vs. Darkstalkers.

Continuing from his previous encounter with Gill, Oni loses his power as a result and reverts back to being Akuma. He desperately seeks a way to restore his demon form. Just then, Donovan appears and seeks to end his existence due to wielding powers comparable to a Darkstalker, but when he sends Dhylec to finish him, Akuma intercepts the great sword and restores his power, becoming Oni again. Before Oni could finish Donovan off, Anita intervenes and threatened Oni. Impressed by the duo's power, Oni tells Donovan to heal himself and seek him out again when he is ready.









  • Oni marks the second time Akuma has discarded his morals to gain more power beyond his Shin or true form (and the first, canon-wise), the first being Cyber-Akuma in Marvel Super Heroes vs. Street Fighter.
    • Despite the fact that Akuma, in Oni form, already discarded his morals and transcended into a god-like demon, he partially lacks the sadism of Evil Ryu and Kage, strongly suggesting that his savagery is still being reined in by Akuma's mind.
    • A form of Shin Akuma similar to Oni was possibly planned for Street Fighter III: 3rd Strike before the character being dropped entirely. Dummied content found in the game's files, including an alternate colored sprite similar to Oni's color palette and a Kousyu Street stage background with an ominous eclipse strongly hints at this.
  • Oni's fighting stance resembles the artwork of Shin Akuma from SNK vs. Capcom: SVC Chaos, and his 6th color also resembles Shin Akuma from Capcom vs. SNK 2.
    • Said stance resembles Misshaku Kongō, the Nio that represents overt power in Buddhism.
    • Ironically in these crossover games, normal Akuma is enough for anyone to see him as a demon; Haohmaru of Samurai Shodown's match introduction has him state "Interesting.... Thoust shall face against a demon!"
  • Oni is one of the five characters to physically interact with defeated opponents (the others being Urien, Q, Rolento and Necalli), and the only one in the Street Fighter IV series. He picks them up by their heads, then supposedly deals an off-screen fatal blow.
    • Also, if Oni uses an Ultra Combo as a finishing move, no "KO" sign will be shown on the screen, much like Akuma's Super Combo and Ultra Combos; they also share the same Ultra Combo Finish background.
  • Oni is the only character besides E. Honda that recognizes that Cody, while still wearing very loose chains, is in fact holding back on all his battles. Unusually, the "boss" version of Oni actually implies that Cody might survive a battle with him if he doesn't hold back; the playable version calls Cody a coward.
    • If Cody wins against the boss Oni, it is the only time (besides fighting Ryu) that he admits having fun.
  • Characters introduced in Ultra Street Fighter IV does not have unique boss intro speeches from Oni, and are instead recycled from existing characters. The same would prove true for said characters in Evil Ryu's boss intro.
  • There is unused data for Oni which is comprised of mostly Akuma's neutral and close punches and kicks, includes a fully complete and functional Ashura Senku, which would only be used during the Shun Goku Satsu. He also has a descending dash which is used for his Sekisei Jiraiken, and the Tenmakujinkyaku.[citation needed]
  • In Street Fighter vs. Darkstalkers and other depictions of him from UDON comics, Akuma is fully aware of his own capabilities as Oni and despite being engulfed totally by the Satsui no Hado, is implied to still perfectly establish control over his powers, and that his violence is not mindless. In the former's first encounter with Donovan and Anita, he stood down upon realizing their powers. He then told Donovan to heal his own wounds and then seek him again when ready.
    • His assertiveness of a fair fight in full power can be comparable to that of Vergil's honorable fight ethics, from the Devil May Cry series.
