Satsui no Hado (lit., Surge of the Murderous Intent)
The Satsui no Hado from the Street Fighter games is also present in the story. As usual used by Akuma and (Evil) Ryu.
Satsui no Hado is a form of energy that is rooted in both the darker aspects of natural human instinct (including the desire to survive, trample, and impose over opposition), and, on a metaphysical level, the natural occurrence and manifestation of loss, decline, and destruction.
To tap into the Satsui no Hado, a fighter must be so consumed with the desire to win, or else possess such intense rage, that they are willing to kill, As such, only those who push themselves to be the best at all costs can take full advantage of it. Learning Satsui no Hado is the first step in learning the most fatal technique known to all of their martial arts - the Shun Goku Satsu (lit. Instant Hell Murder) or also known as the Raging Demon.
In the Street Fighter X Mai-HiME storyline, Gouken believes that HiMEs like Mai Tokiha, Natsuki Kuga, and/or Mikoto Minagi may have a possible connection to the Satsui no Hado, with allowing a chance to extract their powers onto Ryu so it won't take over him. However, neither of the three have no knowledge about the Hado, not only until it was revealed that only Shizuru Fujino has the knowledge about the Satsui no Hado and passes it to her friend, Natsuki. Which the latter is aware of; Shizuru warns the gang that Ryu must not fight Akuma at all costs, which it happened later on.
During a fight between Akuma and Ryu, Natsuki tries to revive the latter by exchanging elemental ki's, half Natsuki's HiME power and Ryu's Satsui no Hado being extracted at each other. However, Natsuki refuses to submit to the evil power. Which led to her using to a minor degree that doesn't taker her over. With Natsuki under the influence of the Satsui no Hadou, she along with Ryu gained the "Hado Kakusei" (lit. Surge Awakening). In this form, Ryu envelops himself in a blue aura and turns his eyes a pure white (as seen in Ultimate Marvel vs. Capcom 3), Natsuki also gains the Hado Kakusei after gaining the Satsui no Hadou.
In the Street Fighter EX series, the Satsui no Hado is said to awaken an evil entity known as Garuda.
In the Street Fighter roster, fighters who oppose the Satsui no Hado are Gouken, Ken Masters, Juri, Sagat, Ingrid, Rose, Guy, Sakura Kasugano, and even Ryu himself. While in the Mai-HiME roster who oppose the Satsui no Hado are Shizuru Fujino, Natsuki Kuga, Nao Yuki, Nagi Homura, Miyu Greer, and Alyssa Searrs.
On the other hand, the Satsui no Hado is implied to be the TRUE weakness of the Obsidian Prince. Depicted when Oni unleashes a Meido Gohado on the latter. At the same time it brings utter destruction to the HiME star, when Natsuki does Akuma's Demon Armageddon, destroying it.
Psycho Power
This is M. Bison's trademark power. This demonic force emphasizes use of telekinesis and mind control. And this is proven to be the opposite to Rose's Soul Power
Often termed as dark, negative or psychotic, Psycho Power is most notably exploited by its best known user, M. Bison, who utilizes the Psycho Drive to channel it. Psycho Power has been described as the corrupted negative of Soul Power, a power demonstrated by Rose; this may be true, consdering Rose is the formation of Bison's expelled "good" energy.
Soul Power
The Soul Power is an ability possessed by Rose in the Street Fighterseries. It is best known as the antithesis to the corrupted Psycho Power, wielded by the heartless M. Bison.
The Soul Power is, as its name implies, energy manifested from the soul. In appearance, Soul Power is a kinetic, color-changing energy that Rose channels from her body and often through her scarf, allowing her to control it as a weapon and supplement her attacks with Soul Power. It can be released as projectiles of concentrated energy, zap her opponents, and project temporary copies of herself.
Rose's tarot cards have an additional link to her Soul Power, as seen when Rose quick-changes after a battle with an enlarged "The Fool" card. Soul Power also grants her the ability to seal foes within (presumably blank) tarot cards and seal off evil energy; however, she cannot see a person's fate if they are from the future, such as Ingrid.
In the Street Fighter X Mai-HiME storyline, after Natsuki gains knowledge about the Satsui no Hado from Shizuru, she seeks to ask help from Rose, who in turn lends her one of her specials; the Soul Sattelite (that appeared as an Ultra Combo in Super Street Fighter IV) in order to shield herself from Akuma and (Evil) Ryu's Raging Demon that can cost her (Natsuki) life.
HiME
A HiME refers to the ability to create solid objects from photons, as well as the females who wield this ability. It stands for Highly-advanced Materializing Equipment. It is a backronym of hime, the Japanese word for princess. All HiMEs have an identical birthmark shaped like the HiME symbol on various points of their bodies, usually the part of their bodies governed by their astrological sign. HiMEs typically are associated with a classical element or some other theme.
In the anime, only a few HiMEs are initially revealed. They are dependent on their most important people for their Childs. There are 13 HiMEs: Natsuki Kuga, Mikoto Minagi, Mai Tokiha, Akane Higurashi, Midori Sugiura, Nao Yuuki, Akira Okuzaki, Yukariko Sanada, Yukino Kikukawa, Alyssa Searrs, Shiho Munakata, Fumi Himeno, and Shizuru Fujino. Of the 13, Alyssa is the only artificially created HiME.
In the manga, HiMEs are public knowledge, with students cheering on battles. HiMEs require Keys to summon their Childs. There are 16 ordinary HiMEs: Mai Tokiha, Natsuki Kuga, Yoko Sagisawa, Mikoto Minagi, Akane Higurashi, Haruka Suzushiro, Yukino Kikukawa, Nao Yuuki, Akira Okuzaki, the Three Scale Sisters, Midori Sugiura, Saeko Kuga, Mashiro Kazahana, and Fumi Himeno. In addition to the regular HiMEs, PRINCESSes and QUEENs are also HiMEs but have different characteristics.
In the Street Fighter X Mai-HiME storyline, as said above; Gouken believes that the HiMEs may have a possible connection to the Satsui no Hado, however when Ryu, Ken, and Sakura brought Mai, Natsuki, and Mikoto before Gouken, the three HiMEs have no knowledge about the Satsui no Hado not until Shizuru was the one who was aware of the evil Hado and then passes it to Natsuki. In addition, the HiMEs can adopt and learn special attacks from different characters from the Street Fighter roster; including Ultra Combos. For example, Natsuki can gain Ryu's Shin Shoryuken.
Element
Element is the name for the objects the HiMEs can create. Most take the form of some kind of weapon, but a couple have non-combat functions such as Yukino's mirrors. All natural HiMEs wield Elements, while artificial HiMEs cannot.
In Street Fighter X Mai-HiME, Crimson Viper has the ability to amplify the power and acoustic signature of a HiME's element and child, for some reasons Viper passes some of her special attacks to Mai such as the Thunder Knuckle and Burning Kick.
Child
A Child is a creature summoned for battle by a HiME. Most have some origin in mythological beasts or deities.
In the anime, Childs can be summoned anytime after a HiME has accepted her Child. They are linked to a HiME's most important person; when the Child dies, the HiME's most important person also dies, and the HiME loses her powers.
In the manga, a HiME summons a Child by touching her Element to her Key. The death of a Child results in the death of the Key. PRINCESSes and QUEENs do not need Keys to summon their Childs.
In general, the manga Childs are significantly stronger than their anime counterparts, as evident by their much larger size and significantly stronger attacks. This is due to some of the differences between the two stories; in particular, the mortality of the Childs plays a significant role in the anime, whereas in the manga the Childs are intended to be superpowers.
While in Street Fighter X Mai-HiME, there are some Childs can perform Ultra Combos in behest of their owners and the specific fighter who uses the move; for example Mai's Kagutsuchi can use Dhalsim's Yoga Inferno/Yoga Catastrophe and Rufus' Big Bang Typhoon, Natsuki's Duran can use Rose's Soul Spark and Remy's Light of Justice.
Fuka Academy
Fuka Academy is the private school at which all of the HiMEs are gathered. It has 3 buildings for grade school, middle school, and high school, which are all connected by the Crystal Shrine. Its chairwoman is Mashiro Kazahana.
The Fuka Academy Student Council holds more power than typical student councils; they are in charge of student discipline and are partly responsible for school funding. Its president is Shizuru Fujino. In the anime, Reito Kanzaki is the vice president.
Part of the Student Council, these students specifically deal with maintaining order at Fuka Academy. The chief executive is Haruka Suzushiro, who is assisted by Yukino Kikukawa.
HiME Star
The HiME Star is a red dwarf star in the sky, located to the lower-right of the moon. It is encircled by a rocky structure similar in shape to the HiME symbol. The HiMEs' powers originate from the Star.
In the anime, only the HiMEs and the First District can see the Star. The Obsidian Prince states in the final episode that the Star is the source of his powers. Its subsequent destruction weakens the Obsidian Lord, allowing him to be destroyed.
In the manga, the HiME Star is visible by all. During the final chapters of the series, it becomes the Obsidian Palace. This also happens in Street Fighter X Mai-HiME before Natsuki clashes Akuma/Oni.
In Street Fighter X Mai-HiME, the HiME Star and the Obsidian Lord are vulnerable to demonic embodiments of all that is the Satsui no Hado.
On the other hand, two Street Fighter characters may gain more power from the HiME Star in different cases. For Akuma, should he look on into the star at night, the energy that emnates from the Star will merge within Akuma, resulting the Satsui no Hado to reach at its peak. In this form, Akuma's hair will whiten, and his skin receives a dark coloration and the color of his karategi becomes darker purple, similarly seen in his Capcom vs. SNK 2 incarnation. As usual, the kanji displayed on his back is always the 'Shinjin' version (神人); as for Bison's case, in order for him to gain the power from the Star, he must acquire one HiME as a sacrifice in order for him to boost his Psycho Power to its fullest extent. In this state, Bison is extremely powerful -in a similar nod in Street Fighter Alpha 3 to his "Final" Bison incarnation - that makes him a formidable force be reckoned with; on that note, he would likely outmatch the Obsidian Lord's power.
Most Important Person
A vaguely defined term in the series, first mentioned by Nagi Homura in episode 2. The person most important to a HiME becomes collateral in exchange for the power of a Child; if a Child dies, the most important person dies also.
In Street Fighter X Mai-HiME as said above, but with one exception; if a HiME possesses the Satsui no Hadou, the most important person survives. And in the said story, there are two HiMEs to have more than one most important persons; Natsuki is revealed to have two most important persons, the first one is Shizuru Fujino, and the second being Ryu. While Akane Higurashi has three persons most important to her, aside from her boyfriend Kazuya Karauchi; two more from the Street Fighter EX series - Hokuto and Nanase, are also implied to be close friends with Akane in the story.
And of that note, Natsuki and Akane are the only HiMEs to have additional persons most important to them who come from the Street Fighter roster.
Seal of Blood
The Seal of Blood is a cursed power that was implanted to Hokuto by the Mizukami clan. The Seal of Blood within Hokuto will come to life whenever Kairi is in her presence. Unknown to Hokuto, her true purpose of her mission to locate Kairi was to carry out his elimination. To ensure this, Hokuto was implanted with the Seal of Blood by the elders of the Mizukami clan, which was set to be unleashed whenever Hokuto would come into contact with Kairi. Bloody Hokuto can be distinguished from her regular counterpart by the red mark on her forehead.
In Street Fighter X Mai-HiME, the only way to suppress the Seal of Blood in Hokuto is when the latter should be in the presence of a HiME; such as Akane Higurashi and/or Shizuru Fujino.
Orphan
An Orphan is a creature the HiMEs fight. They typically have a monstrous form. Nagi Homura is the one generally responsible for summoning Orphans.
In the anime, Alyssa Searrs can also summon Orphans to carry out missions for the Searrs Foundation. Orphans are described the same as Childs, but with a distinct difference - they lack the capability to resonate with the soul of a HiME, and instead are attracted to the emotions at Fuka Academy.[1]
In the manga, Mikoto Minagi keeps an Orphan as a pet, which is the focus of chapter 20.
Interestingly, unlike Childs, Orphans appear biological, rather than the biomechanical appearance of other similar creatures(Childs of Mai Hime and Slaves of Mai Otome).
In Street Fighter X Mai-HiME, Nagi mentions that there are other entities are also controlling orphans; in one case, the Psycho Power. Bison also captures Orphans and uses them to do his bidding. Akuma also mentioned that there are Orphans have fear on anyone in general who utilize the Satsui no Hado such as himself and Evil Ryu.
Searrs Foundation
The Searrs Foundation is an ancient organization disguised as an American corporation. They seek to take the powers of the HiMEs for themselves with the help of technology. Alyssa Searrs and Miyu Greer work for Searrs.
In the anime, Searrs uses Alyssa, Miyu, and Father Greer to observe the HiMEs. In episode 14, Searrs sends its private military to take over the school. The coup fails, and Searrs later sends John Smith to make amends with the Obsidian Lord and deal with Miyu.
In the manga, Searrs owns a private school, the Searrs Female Institute, which sends Saeko Kuga and a delegation of PRINCESSes to take over Fuka Academy and open the HiME Star's gate. Searrs later retracts its orders, but the HiME Star is opened anyway.
In Street Fighter X Mai-HiME, similar in the anime, and it is also a neutral faction. The Foundation is being targeted in suspicion by the Interpol, Central Intelligence Agency, and the Joint Special Operations Command; who are aware of the Foundation's motives. On the other hand, the Foundation faces crisis when some of its employees (including John Smith) were massacred by Garuda; who was looking for Natsuki's mother, whom the latter spared during the incident. And later was taken over by Shadaloo.
Obsidian Prince
The Obsidian Prince is a being who is the main antagonist of the series, using the powers of the HiMEs to his own ends. The Obsidian Prince possesses one of the characters, but is not revealed until the final parts of the series. He seeks to recreate the world to his own desires by using the powers of the strongest HiME. In the anime and Street Fighter X Mai-HiME, Reito Kanzaki is the vessel for the Obsidian Prince, while Takumi Tokiha is the vessel in the manga. The Obsidian Prince's true weakness is none other than the Satsui no Hadou as said above, when Oni performs his Meido Gohado on the Obsidian Prince; it also left Reito critically wounded.
Akuma's Forms
Akuma has three forms in Street Fighter X Mai-HiME.
Shin Akuma
Shin Akuma (真・悪魔, "True Demon" or "True Devil") or in Japan, Shin Gouki (真・豪鬼, Shin Gōki, meaning "True Great Demon", "True Great Ogre" or "True Great Devil") or (神人・豪鬼, "God Great Devil") is a secret fighter and a boss in the Street Fighter series based on Akuma himself.
His personality remains more or less the same as the original. Essentially, he is Akuma using the fullest extent of his power. However, he is more competitive in battle and less merciful when he is fighting a strong warrior.
The differences between Akuma and Shin Akuma are their priority of their special moves. Shin Akuma is faster, deals more damage and can throw two Zanku Hadoken at once. His special moves also tend to have more priority, negligible startup and recovery compared to the playable version. Also, his Raging Demon is much faster and travels farther (making it harder to evade), and in some instances, inflicts more damage (e.g. Capcom vs. SNK 2). In some instances, Shin Akuma also has extremely powerful specials as well (e.g. Misogi).
In Street Fighter X Mai-HiME, Shin Akuma appears in his Capcom vs. SNK 2 incarnation, this form of Akuma achieves a new level of power when a dying Rugal Bernstein pours his Orochi Power into him, driving Akuma insane, whitening his hair and turning his skin much darker than usual as a result of all the dark power flowing within him. As a wordplay, the 'Shin' in his name denotes 'Divine' instead of the usual 'True'. The unique kanji seen on his back during certain animations is composed of 'Kami' (神, "God") superimposed over 'Hito' (人, "Person"), expressing the idea of a person who has become a god and much beyond that of an ordinary human. The kanji can also be interpreted as 'Shinjin' (神人), which translates to "Lesser God". Shin Akuma in the crossover story is awakened as a result of the HiME star granting him more power.
Cyber Akuma
Cyber Akuma (Mech Gouki メカ豪鬼 Meka Gouki in Japan), a version of Akuma mechanically enhanced by Apocalypse; the enhancements include a mechanical right arm (dubbed Booster Rocket), metal wings, and four extra arms that are only seen in one of his win poses. As such, his personality is vastly different from that of Akuma's, being more servile (as reflected in his win quotes). Gameplaywise, however, Cyber Akuma fills the same role as Shin Akuma.
In Street Fighter X Mai-HiME, Cyber Akuma is formed when Duran (Natsuki's Child) fuses with Akuma.
Oni
Oni is Akuma united with the Satsui no Hado, turning him into a full demon. This form of Akuma is slower but stronger in terms of brute power, compared to the original. However, Oni lacks the technical finesse displayed by the regular Akuma. This demonic transformation allows Akuma to use an air dash, and grants him several new attacks, such as a forward slide which slashes at the opponent as he passes and a overhead ground stomp. However he loses the Ashura Senku, Tenma Kujin Kyaku and the Hyakkishu. Oni can perform the Raging Demon in the air.
QUEEN
These are powerful HiMEs in the Mai-HiME manga enhanced by the power of the Obsidian Prince. This acronym stands for Quaint Elemental Enchantress. The three QUEENs in the manga are Marie Antoinette, Yang Guifei and Mai Tokiha.
In Street Fighter X Mai-HiME, the term QUEEN is a title given to a HiME who utilizes the Satsui no Hadou. In one case, Natsuki Kuga. According to Gill, a HiME will be addressed as a QUEEN when she has put the Satsui no Hadou to its fullest extened and becoming one with her power. The said HiME will NOT sacrifice her humanity if she has benevolent intentions of using the Satsui no Hadou to destroy the Obsidian Prince. In order to destroy the Obsidian Prince, the QUEEN must summon all warriors (namely several characters from the Street Fighter roster) and the other HiMEs to gang up the Obsidian Prince by performing their Ultra Combos against him, before Oni can do his Meido Gohado.
Shadaloo (or Shadowlaw)
Shadaloo is a very powerful and deadly criminal organization that is responsible for dealing biochemical drugs and arms in the Street Fighter universe. Shadaloo is headed by M. Bison and his three highest minions, Balrog, Vega and Sagat (lowest to highest).
Shadaloo's motives, capabilities, and scope were much further revealed. The crime organization appeared to be paramilitary, with very powerful capabilities. Shadaloo bases were identified in Thailand and Brazil that seemed to contain technology and weapons sufficiently advanced to rival a medium-sized nation. Bison had control of a very large VTOL (vertical take-off landing) jet and employed scientists to create cyborgs, clones, human experiments, mind-control rays, satellites, powerful weaponry, large-scale attack robots, and the Psycho Drive.
Initially, Shadaloo's goals and scope were ambiguous at best. They appeared to be smugglers, though of what is not explained. Bison is described as "ruling his empire with an iron fist", possibly indicating that he controlled some independent territory. Each of the bosses were motivated by their own self-centered desires, and accepted Bison's offer to join his rank based on wealth or opportunity. Balrog was hired as an enforcer to expand his wealth, whereas Vega was a well-paid assassin. Sagat was Bison's right-hand man and Shadaloo's second-in-command, who was motivated by revenge against Ryu; after the events of Street Fighter II, Sagat left Shadaloo, and vows to fight Ryu in his own terms.
In Street Fighter X Mai-HiME, the syndicate's function remains intact. The said group is involved in many common crimes such as kidnapping, drug trafficking, coercion, and many acts of terrorism. Shadowgeist now fulfills the vacant role of the defected Grand Master Sagat, since the latter has severed ties with Shadaloo.
Illuminati
Based off real-life rumors of an organization with the same name, the Illuminati in the Street Fighter series has existed for thousand of years in the regions of the world often renowned for their powerful and influential civilizations (most notably Egypt and Greece), manipulating world political, social, military, and even criminal events (Shadaloo included) in order to achieve an ancient apocalyptic prophecy that would lead to a new age dominated by them.
While the prophecy would not come until another two centuries, Gill, the appointed leader in the late 20th Century, would take it upon himself to create a nation comprised of the fittest and best that humanity had to offer in order to bring about the salvation of the human race after the prophecy had taken its course, feeling that the world's opposing forces have become unstable and imbalanced; Gill saw that through the world's state of rapid change, increasing modernization, and uncertainty to the 21st Century, the social, cultural, environmental, political and ethical issues had grown alongside it.
To achieve this, he set several plans into motion. One revolved around an organized fighting tournament to seek out the "worthy", and another included the conduction of illegal genetic experiments to create a race of super soldiers, called the G-Project, giving way to the prototype Necro and the soldier Twelve.
Despite their intentions, they are hypocritical in their methods and are no better than powerful criminal organizations such as Shadaloo themselves. The Illuminati stoops to kidnapping, coercion, DNA manipulation, brainwashing, extreme force, and funding themselves on criminal activity and the black market; their philosophies and ideas of thought border on elitist, and consist of brutal Darwinist and authoritarian principles they would build their new world order on.
In Street Fighter X Mai-HiME, the group's function remains intact. That now they are at war against Shadowlaw, as far as Gill is concerned, he implies that Bison was usurping chaos. Much to Gill's dismay, although he wants to restore the world to its peaceful state. Illuminati is later revealed an ally when Gill reveals to Ryu and company that he is planning to stop Bison's evil plans of world domination.
Having existed since the early ages of human civilization, the Illuminati nonetheless have control over nearly every field of society, with members and their influence in the upper ranks and hierarchies of governments, corporations, and even the criminal underworld to carry out their bidding.
While also manipulating events and politics throughout the world, they are also seemingly in command over the flow and access of information and knowledge in the world, being shown and said to hold access to technological and scientific innovations at least generations ahead of what is known to humanity in their current period (cryogenics and cranial preservation was shown to be 2000 years accessible to the organization prior to the Information Age, after the BC era), and knowledge and proof of existence of the occult and metaphysical, such as the utilization of Qi, Chakra, elemental manipulation and harmonizing, and to a lesser extent, magic; through which all occult knowledge they have access to, they have also created and developed extremely powerful techniques unique only to its members, titled the 66 Secret Arts of the Illuminati.
Likely through the technological and scientific knowledge they possess, the Illuminati is likely responsible to have influenced and given society outside all previously kept innovations and discoveries to create what is now the modern day.
Ultra Combo
Ultra Combos are a very powerful type of move introduced in Street Fighter IV. To perform an Ultra Combo, a player enters a combination of buttons (usually a modified combination of a Super Combo combination that involves pressing all three Punch/Kick buttons at once rather than just one Punch/Kick button) with a sufficiently charged Revenge Gauge (which is the left side of the Super Gauge at the bottom of the screen) by receiving and blocking blows or absorbing hits with Focus Attacks. The Ultra Combos are called "finishing moves" by fans, as it is considered the best way to finalize your opponent with style, but if you throw it out randomly, it will likely not connect, leaving you vulnerable.
They are often stronger versions of certain moves (i.e. Akuma's Wrath of the Raging Demon). In some cases, the moves are reprised from earlier appearances in the series (i.e. Cody's Final Destruction). In other cases, they are moves that the user may have just discovered, or else have made their first appearance in the Street Fighter IV series.
In Street Fighter X Mai-HiME, a HiME (i.e., Mai, Natsuki, Shizuru, Mikoto, and Midori) can gain Ultra Combos after encountering many warriors from the Street Fighter roster throughout the story. Not only a HiME can perform the Ultra on her own, but she can summon the specific fighter who utilizes the Ultra (i.e., for Natsuki with Raishin Mahhaken, she has to summon Yang. But only if the latter is on her side.), sometimes the HiME's child can peform Ultra Combos on the behest of the warrior using it; for example, Kagutsuchi can use Dhalsim's Yoga Inferno/Yoga Catastrophe and even Rufus' Big Bang Typhoon.
Custom Combo
A Custom Combo is a gameplay element introduced in and exclusive to the Street Fighter Alpha series.
The Custom Combo system was introduced in Street Fighter Alpha 2 to make up for the limited Chain Combo system in said game. It returned in SFA2: Gold and every version of Street Fighter Alpha 3. The Custom Combo can be done with any character, but requires at least a level one or higher Super Combo Gauge.
When two punches and a kick or two kicks and a punch are pressed, a noise will emit and the character will do a small action to indicate the successful start of a Custom Combo. The character will then begin to move faster and leave purple shadows behind whenever the character moves. The character will also begin moving slowly forward by his/herself.
Once activated, the player will have a limited time to approach a foe and launch any series of attacks they wish. The attacks done will be done much faster than in regular gameplay, and easily done in succession. In addition, any special attacks can also be done much faster and without any charge time (if needed). Lastly, characters hit with "knock down" attacks can still be immediately attacked afterwards, provided they do not fall to the ground. Skilled players can figure out ways of making lengthy combos that cannot be escaped normally.
However, the Custom Combo system does have drawbacks. Above all, if the character is attacked while doing a Custom Combo, it is ended immediately and the Super Combo Gauge will be emptied. The Custom Combo is of notably short length, usually only a few seconds, and the length depends solely on how much the Super Combo Gauge is filled.
Despite being exclusive to the Alpha series, a few "Custom Combo" attacks have appeared in the series since its introduction. Yun and Yang both have Super Arts (Genei Jin and Seiei Enbu, respectively) that cause them to leave behind after images which cause more stun damage, making combos easier to string together. Juri's Feng Shui Engine Ultra Combo in Super Street Fighter IV causes the Revenge Gauge to become a timer and allows Juri to chain together more combos than she normally could.
While in Street Fighter X Mai-HiME, the Genei Jin, Seiei-Enbu, and Feng Shui Engine returns, along with the Hadou Kakusei from Ultimate Marvel vs. Capcom 3, and can be accessible to Ryu and Natsuki. For Natsuki's case, she can transform into different modes; Awakening and Materialize modes. The Awakening mode animation remains intact from Ryu's version, while the Materialize mode allows Natsuki to transform into her Meister Robe from Mai-Otome.
Desperate Attack
Also known as a forbidden move. It is based and is referenced from those seen in the Street Fighter III games, namely from 2nd Impact and 3rd Strike. In this said game, characters such as Gill and Akuma can gain access to several Super Arts in different cases; for Gill, since 2nd Impact, he has two Supers, and by the following sequel, he has three; namely Meteor Strike (2nd Impact) and Seraphic Wing (3rd Strike) in addition from his Resurrection. Gill can gain access to all three Super Arts and is not selectable in the character select screen of the game. As for the case of Akuma, from 2nd Impact, aside from three selectable Super Arts, he has only one hidden move; which is the Shun Goku Satsu. While in 3rd Strike, he has another one; the Kongou Kokuretsu Zan. Of that note, it can be used no matter which Super Art was chosen at the character select screen, and uses up the whole super gauge. This means that in 3rd Strike, in any given match, Akuma has access to three Super Arts, making him extremely dangerous.
In Street Fighter X Mai-HiME, this is also a term for 'hidden' Ultra Combos, and there are only two HiMEs who have desperation attacks; Natsuki Kuga and Mikoto Minagi. For Natsuki's case, she satisfies from those of the case of Akuma; three are all Satsui no Hado-powered attacks, namely the Kongou Kokuretsu Zan, Metsu Shoryuken, and Nekketsu Hadoken; the attacks were belonged to Akuma and Sakura respectively. As for Mikoto's case, she only uses one; the Last Dread Dust; one of Cody's Ultra Combos, which the other being the Final Destruction. As usual with Cody's version of the ultra, Mikoto will always use a steel pipe other than Miroku.
In addition, the villains in the said crossover story also have forbidden moves on their own. For example, Bison is known for many Ultras, his only desperate attack is his Final Psycho Crusher seen in Street Fighter Alpha 3; it inflicts powerful damage at vulnerable foes.
