Street Fighter Wiki

The kanji '天' ( ten?, "heaven") representing the Satsui no Hado.

The Satsui no Hado (殺意の波動 Satsui no Hadō?, "Surge of Murderous Intent" or "Surge of Killing Intent"), sometimes translated as the Dark Hado, is a dark energy-based force that is known for its use by Akuma. It is the antithesis of the Power of Nothingness, which is mainly used by Gouken and Ryu.


Satsui no Hado made its first debut alongside Akuma in Super Street Fighter II Turbo. During the events of Street Fighter V, the Satsui no Hado within Ryu was being called out by the consumer of souls. However, in the end, Ryu managed to control and overcome the Satsui no Hado inside him by tapping into the Power of Nothingness also called Kyosui no Hado to seal Bison. It later manifested into a physical form known as Kage, though later on he apparently vanished from existence.


What the Satsui no Hado is, rarely gets talked about in the mainline games. However, it's described as taking the spirit to kill the opponent to the extreme, and transforms it into a physical power. Martial arts made towards the purpose to kill, specifically Ansatsuken, come to have their repertoires and teachings intertwined with its power upon their founding, and their techniques ultimately hold the potential to develop the Satsui no Hado due to its originating intention.[1] Alternately, according to Seth in Street Fighter IV: The Ties That Bind, his definition of the Satsui no Hado has him describe it as power rooted in the darker natural basis of the human instinct, including competition, survival, to trample on, impose, and thrive over opposition, and the manifestation of destruction borne out of conflict and fighting.

Physical and Mental Changes[]

For the people who do succeed in harnessing it, they become extremely powerful, but at the cost of losing their humanity and compassion; they develop a cold, negative outlook on life, a nihilistic detachment from themselves, as well as other people, and develop an obsessive, dark, murderous, and even suicidal desire to fight.

When under the Satsui no Hado's influence, a person's eyes will glow red and their teeth will extend into sharp fangs, and their skin darkens over time. Their hair also turns red, and their nails grow into claws. The voice of the user will also become deeper to the point of gaining an echo effect. If one embraces it to a lesser degree, their eyes will glow blue. If one balances the Satsui no Hado and the Power of Nothingness, they will be in complete control of their power; however, if one has used it to their fullest extent for too long, they cannot be released from its hold and will transform into a supernatural entity, likely one similar in appearance and personality to both Oni and Kage.

Powers and abilities[]

A user of the Satsui no Hado gains immense strength, as well as the ability to both sense and absorb other sources of power to make themselves stronger. They also gain abilities such as telekinesis, flight, and can also potentially influence the emergence of the Satsui no Hado in others. Once an individual has tapped into the Satsui no Hado within them, it can be very difficult to resist conflict. Learning the Satsui no Hado is the first step in learning the most fatal technique known to all of their martial arts - the Shun Goku Satsu, also known as the Raging Demon.

From within the events of Street Fighter Alpha: The Animation, the Street Fighter Alpha manga, Street Fighter IV: The Ties That Bind, and the UDON comic series, the user has apparently the special ability to talk and speak with others telepathically, gain a healing factor, and manipulate the soul of an individual and the weather, as seen and displayed with Evil Ryu and Kage.


Street Fighter characters[]


Goutetsu himself was once seen meditating while tapping into the Satsui no Hado, so he probably encouraged or at least accepted it, but he did not lose his humanity like Akuma. This is likely because he only used it sparingly and wisely, which is why he kept his human facial appearance and did not demonstrate signs of corruption. This was also how both of his students, Gouken and Akuma, were introduced to Satsui no Hado and Power of Nothingness.


Akuma's usual form.

Once Akuma fully gave in to the Satsui no Hado, he lost all of his human emotions and was solely motivated by violence.

Goutetsu was initially pleased and somewhat impressed with Akuma for tapping into Satsui no Hado during a life or death battle for control of their school. Akuma wanted to tap into the Satsui no Hado to become more powerful, and wanted to use it to kill people he found "worthy", rather than using it for enlightenment and good like his mentor. Goutetsu may have been unaware of his student's descent into madness.

However, Gouken developed an alternative derivation of the style by removing the dark power out of fear and disgust for the Dark Hado, as he believed it to be inherently evil, as a result of seeing how Akuma used it to murder Goutetsu. He condemned his brother for corrupting his Hado no Chikara (波動の力 Hadō no Chikara?, "Surge of Power") and vowed to never teach it to anyone.

Although Akuma may have "mastered" the Satsui no Hado, he could not stop the side effects of this dark force, although it is highly likely he had no desire to. His understanding of the Satsui no Hado is so great that he can embrace it to a much lower degree, giving lesser opponents a fighting chance. However, he still cannot return to human form, as he has used it to his fullest extent for too long.

According to the story mode for Akuma in Street Fighter V, Akuma's skin has cracked and peeled away, leaving only the Satsui no Hado to show itself.


Oni is the result of Akuma fully merging with the Satsui no Hado. As explained earlier, his appearance has changed to that of a larger, demonic creature with a supernatural power beyond that of Shin Akuma. At this point, he has become a marauding berserker willing to kill anyone and anything, especially if he deems someone as a greater evil, such as Bison and Seth.

Evil Ryu[]

Although Ryu never shows any signs of the Satsui no Hado's influence after the events of the Street Fighter IV series, several games present a hypothetical version of Ryu who has embraced the power, willingly or not, becoming Evil Ryu in the process. Furthermore, other media often depicts him temporarily succumbing to the Satsui no Hado and assaulting an opponent before returning to normal.

It was not until the end of Street Fighter IV that Gouken was able to seal it away using the "Power of Nothingness" to help him control it like Goutetsu; however, it is unknown how long the seal will be able to hold his dark power. Until in Street Fighter V, Ryu acquires a help from his friends Dhalsim and Ken, and thus manage to completely convert the Dark Hado into Power of Nothingness via Hado Kakusei during Necalli’s invasion on planning to devour him at the same time where he and the other Street Fighter heroes prepares for last battle against Shadaloo. A demonic version of Evil Ryu appears in the Arcade Edition of Super Street Fighter IV with an appearance similar to that of Akuma, possibly to show how he would transform if the seal was broken.

In addition, Ryu and Ken's ending in the crossover Street Fighter × Tekken suggest that Pandora's power is trying to influence and merge with the Satsui no Hado within him.


Kage is the physical manifestation of the Satsui no Hado that was dwelling within Ryu. After Ryu overcame the temptations of the dark energy, it was assumed that the persona of Evil Ryu had been vanquished. Yet the Satsui no Hado would develop sentience and came to manifest as its own entirely separate, physical entity known as Kage. He wanted to prove that Ryu is nothing without him, but failed due to Ryu mostly ignoring the dark influence, telling Kage that he can do whatever he wants. Distraught and confused, Kage vanished.

Shin Ryu[]

Shin Ryu

In the UDON comic book series Street Fighter Unlimited, Ryu finally attained complete control over the Satsui no Hado by entering a state he calls "Shin Ryu" (Shin meaning "True" in Japanese). This state allows Ryu to safely harness the Dark Hado by merging it with the Power of Nothingness, bringing balance to his light and dark ki. As Shin Ryu, he was able to finally defeat Akuma. Ryu's appearance in this form is mostly the same, the only noticeable changes are to his left eye, which glows red, as well as the occasional flare of a red and blue aura.

Dan Hibiki[]

In the events of UDON's Street Fighter Legends: Sakura comic, Dan falls to the dark power while fighting Sakura. However, Dan's attempt to perform the Shun Goku Satsu on her fails with him tripping over her backpack and rendering himself unconscious by Sakura's attack.

Dan has a different kanji appearing on his back, showing the kanji ( chichi?, "father"). It is possible Dan's power stems from the feelings of hatred that he harbors towards Sagat for murdering his father.

Despite Dan's paltry skills, Gouken is well aware that such power can manifest to anyone, especially with a vengeance-motivated man like Dan, and become a proper threat in time. This is why Gouken expelled him from his dojo and deprived him of proper Ansatsuken teachings.

Sakura Kasugano[]

In UDON's Super Street Fighter comics, Sakura actually falls to the influence of the Satsui no Hado[2] while fighting Akuma but loses it thanks to Ryu absorbing it.

In Marvel Super Heroes vs. Street Fighter, there is a secret character known as Dark Sakura (also called Sunburnt Sakura), a version of Sakura who utilizes a mixed moveset of Akuma and Evil Ryu. Despite her abilities, this form of Sakura does not use the Satsui no Hado, as referenced by her article on the Shadaloo Combat Research Institute database. Instead, she is angry because she got a sunburn.

In her normal forms, she also uses a variation of the Shun Goku Satsu that is not fueled by the Satsui no Hado, as seen in both the Rival Schools and the Street Fighter EX series.


In Street Fighter Legends: Cammy, it is stated that Juri's Feng Shui Engine is a getway between Satsui no Hado and Psycho Power that was used to bring back Bison with a new body host.


Sagat's own bout with the Satsui no Hado occurred during his story mode in Street Fighter V. Although not totally consumed by that energy, it has given him darker thoughts and visions of killing. He however overcomes the murderous intent and finally realizes that this is what his long-time rival was fighting against all along. Sagat becomes more determined to fight and seeks more of the same path Ryu always followed.


Oro is capable of utilizing the Satsui no Hado, or what he considers an imitation of it. Though he only uses it as an example for Dhalsim in his lecture on the nature of ki, Dhalsim notices that for that moment, Oro truly held a killing intent. Oro believes that the Satsui no Hado is not an inherently evil power, but rather an alternate form of surpassing physical limits much like Yoga, Soul Power, and Psycho Power. Through this knowledge, he is able to wield it without falling completely victim to it.

Characters from other media[]


In UDON's Street Fighter Origins: Akuma comic, Akuma and Gouken's late father, who is named Gyūki ("Ox Oni"), used the Satsui no Hado years ago to murder the leader of a bandit gang and a former partner of Goutetsu.


In the Street Fighter × G.I. Joe comic, G.I. Joe character Jinx apparently uses the Hado as well in a fight against Bison.


In X-Men vs. Street Fighter, Rogue can copy Akuma's Zanku Hadoken and Shun Goku Satsu.


In the crossover game Marvel vs. Capcom: Infinite, on Earth-30847, Thanos built a containment device in Abel City. This device, a gauntlet of sorts, gave Thanos the ability to drain Ryu of the latter's Hado, which gave Thanos the power to wield the Satsui no Hado by artificial means, presumably with far better control and without the consequences of wielding it.


In Street Fighter vs. Darkstalkers, Belial was able to use this power to stop Jedah from overthrowing his title as the supreme and undisputed ruler of Makai.


In Street Fighter × Tekken, Toro is said to have the Satsui no Hado in him.


In Street Fighter Alpha: The Animation, Shun used the Satsui no Hado when fighting.


In Street Fighter Alpha: The Animation, Sadler was able to gain the Satsui no Hado from Ryu with his technology as a means to rule the world.

Known victims of the Satsui no Hado[]

Street Fighter games[]

  • M. Bison - Defeated and seemingly murdered by Akuma's Shun Goku Satsu in Super Street Fighter II Turbo, but survived the attack by putting by a part of his Psycho Power in another body.
  • Gen - Akuma used the Shun Goku Satsu on Gen during their fight in Street Fighter Alpha 2, but it had no effect on Gen since he had emptied his soul beforehand. In Street Fighter V however, Akuma returned to fight Gen again after realizing he had beaten his illness, thus deeming him worthy to kill. He defeated Gen with the Shun Goku Satsu after years of training harder.
  • Gouken - Defeated and seemingly murdered by Akuma's Shun Goku Satsu, but survived by emptying his soul using the Power of Nothingness.
  • Necalli - Defeated by Akuma in Street Fighter V.

Other media[]

  • Heihachi Mishima - While he survived Akuma's Shun Goku Satsu by sheer endurance and super strength in Tekken 7, he was weakened as a result and due to it, was later defeated and killed by his son Kazuya.


  • While Kairi from the non-canon Street Fighter EX games is not a user of the Satsui no Hado, the power he wields works in a similar fashion.
    • Fellow Street Fighter EX fighter Garuda is also said to be linked to said power in the EX games, feeding from its power for his own existence. A similar power infests Garuda in Fighting EX Layer, but from another source.
  • In the iOS game Street Fighter IV Volt, the Satsui no Hado appears as a skill in Wandering Warrior. However, one would need the title "Messatsu!" to get this skill. When this skill activates, the player's avatar endures the hit that would have cost the avatar the match with 1 HP remaining, and then, it activates. While this skill is active, the damage the player's avatar scores on the opponent's avatar is increased
  • In Street Fighter Alpha: Generations, it is implied that supernatural beings of legend, such as an Oni, were actually people who gave into the Satsui no Hado and because of this, the bloodline of an individual was also altered as well.[citation needed]
  • As stated by Oro,[3] such malevolent powers ultimately share a ground of neutral capability as with all forms of other power; significantly within the history of martial arts, such history also ties in with the nature of human morality and thinking, as many societal factors, including a greater emphasis on the closeness of spiritual affairs with the living world through deeper practice of religion and mystical practices, and the rather fragile developing state of the human condition did not see the immediate execution of outlaws and criminals and death of warriors to be unnatural for their eras prior to the 20th Century and the modern day. Significantly in Japan, this would tie into samurai culture and their purposes in society, from being allowed with degrees of allowance to slay those who threaten society at large, and to help manage their ranks to uphold the honor of their caste, before the abolishment of the samurai caste into the Meiji era by 1868. This would explain why Goutetsu is able to balance his use of the Satsui no Hado.
  • While Akuma (until Street Fighter lll) embraced the full extent of the Satsui no Hado, his moral code served as a means of self-restraint that keeps him from committing indiscriminate assault against his opponents; this becomes non-existent once he evolves into Oni. However, in the case of Evil Ryu (and by extension, Kage), who lacks the moral principles of Akuma, are capable of borderline psychopathy, sadism, and homicidal tendencies due to their insatiable blood lust.[citation needed]


  1. Taking the spirit to kill the opponent to the extreme, it transforms it into a physical power. As a power vector, it resembles Bison’s Psycho Power. Gouken worked to a method to restrain it; instead, Akuma refined it, choosing the path of carnage. It dwells naturally in Shoryuken, Hadoken and Tatsumakisenpukyaku; thus it's possible a user of these techniques like Ryu would wake up to it.
