—M. Bison

Master Bison (Vega in Japan) is one of the main villains of the Street Fighter series of fighting games.



Bison wears a red military uniform with large silver shoulder plates, wrist bands, and shin guards; on his peaked/service cap is the skull insignia of his crime syndicate known as Shadaloo. His clothing highly resembles the uniforms worn by SS officers of Nazi Germany, the winged skull on his visor cap and the first letter of Shadaloo on his belt is shaped as a single sig rune. Bison's eyes lack both pupils and irises, leaving them a ghastly white color. He often wears a dark colored cape when he’s not fighting.


M. Bison is an archelypical villain who is motivated by his own selfish interest and lust for power. He is a ruthless, callous, and an unforgiving dictator with no hesitations for destroying anyone or anything who opposes him. He shows a complimenting side, however, when he states to Karin Kanzuki that he watched her fight with Sakura, and that they fight very well for young girls, and after she defeats the dolls, that Karin did well and is a qualified fighter. While demanding absolute loyalty and obedience from his subordinates, Bison considers them to be nothing more but pawns as opposed to considering them to be human beings, and tolerates his henchmen only as long as they serve his dark ambitions: he decides to exterminate Cammy and the Dolls for becoming useless to his evil plans in the Street Fighter Alpha series and tries to eliminate Seth for usurping him in the Street Fighter IV series. He is not above trying to use coercion by force and brainwashing to convert skilled martial artists to his cause. Bison shows no compassion or mercy towards people and children, considering them to be insingnificant and pitiful wretches not worth living.

As the C.E.O of Shadaloo, he is prepared to gain power and wealth using all possible criminal activites, ranging from drug trafficking and arms deadling to terrorism and illegal human experimentation experimentation. Bison is supermely arrogant and narcissistic with an ego that rivals or may even surpass that of Vega and a penchant for fancying himself as a god. He has nothing but contenpt for his opponents and considering himself the superior fighter for mastering Psycho Power.

Unlike most of the other villains like Gill or Akuma, Bison is in tormenting others, exploiting and ultimately oppressing other people for his own selfish urges. Unsurprisingly, he has earned the hatred from many other Street Fighter charaters such as Chun-Li, Guile Guy, Cammy ,Rose, T.Hawk and many others for his malevolent and sinister nature. Having banished all of the goodness in his soul to control Psycho Power, he possesses a dark and irredeemable spirit. He does display a twisted sense of humor, which not to mentioning his characteristic "business before pleasure" attitude, makes him quite a unique and effective villain in the series, he has no regard for the suffering and damages he causes to others, and that they don't stand a chance against him.



Street Fighter Alpha 2

When Bison hears of a warrior named Ryu who defeated his new henchman, Sagat. Bison decides to recruit Ryu and begins to search him out. In the meantime, he is confronted by Charlie, who questions him on his informants within the U.S. military. Instead, Bison has Nash's own backup helicopter shoot him, knocking him down a waterfall. Bison does not check for a body as he believes he killed him. Bison is also confronted by Rose, a woman who uses a similar power to his, and who tells him to change his ways. Though Rose comes out on top in the ensuing conflict, she is unable to do Bison any serious damage. The third person to oppose Bison is Chun-Li, an ICPO agent who looks for him while searching the whereabouts of her missing father. Encountering Bison, Chun-Li learns that he killed her father some time ago, and vows revenge against the criminal leader and his organization.

Street Fighter Alpha 3

By the time of Street Fighter Alpha 3, the Psycho Power begins exceeding the limits of his body. Having predicted this event, M. Bison had his scientists engineer a body that he could transfer his essence to in the form of Cammy: a genetically engineered young woman using Bison's DNA as a template. He included her in the Dolls: his elite squad of brainwashed young women who serve as assassins. However, over the course of Alpha 3, Cammy's brainwashing begins to weaken and she goes rogue. He sends Vega (one of his enforcers) to retrieve her, and then Juli (one of the Dolls) when Vega fails. Bison then turns his sights to Ryu, a warrior who possesses the Satsui no Hadou, and the worthy rival of Bison's right-hand man Sagat. Bison sends Juni, another Doll, to gather data on on his Satsui no Hadou. Later, Bison finds Ryu and tries to subjects him to his Psycho Power. When Sagat objects, Bison tells Sagat he can finally have his rematch. While Sagat battles Ryu, Ryu's best friend Ken arrive and fight Bison together. With Sagat's urging, Ryu broke free of Bison's Power with the Satsui no Hado and defeats Bison with some of his Satsui no Hado, forcing him to flee. Following an encounter between Cammy and the Dolls, the fully healed Bison decides that the Dolls have no further purpose and chooses to kill them. However, he has not counted on their survival instincts kicking in. Despite their complete loyalty they resist with Cammy's help, and Bison taunts that if the psychic link between him and the Dolls is severed, they will die, meaning that they cannot kill him without killing themselves. Despite this, they kill him and their minds quickly start to deteriorate.

Meanwhile, USAF officers Charlie and Guile are on a mission to stop the dictator. Guile and Charlie are joined by Chun-Li. After learning that the bombardment of Shadaloo was called off due to corruption in Interpol and Bison's manipulation, Chun-Li realized that they would have to destroy the base themselves.

Cammy, with not much time left, takes advantage of her genetic similarity to Bison in order to operate the Psycho Drive. Using it, she removes the psychic fail-safe on the Dolls and saves them.

While Chun-Li and Guile escape the base (which they have rigged with explosives), Charlie keeps fighting the resurrected Bison to allow their escape, and apparently sacrifices his own life. M. Bison's soul, however, ends up surviving the explosion and despite the destruction of the Psycho Drive, takes control of Rose. It is revealed that, while trying to master Psycho Power, M. Bison had to expel all the humanity and good in his soul to accommodate and supplant the intense energy the power gives him, and that Rose is actually the formation of all of M. Bison's good energy. He stays inside of Rose's body until his Shadaloo scientists forge a new body for him.

Super Street Fighter II

M. Bison then holds the second Street Fighter tournament to get revenge against the people who opposed him during the events of Street Fighter Alpha 3—especially the ones that destroyed the Psycho Drive—and to lure out Ryu to gain his body once more. His Psycho Power seems to have significantly diminished since the destruction of the Psycho Drive, but he is still very powerful. His plans are foiled when Akuma interrupts the tournament wishing to fight the finalist of the Bison's tournament. He defeats Bison with the Raging Demon, destroying his body in an instant.

Street Fighter IV

At some point before encountering Ryu and Akuma, Bison ordered the creation of at least 26 androids by S.I.N., the weapons division of Shadaloo. #15 was chosen to be the new head of S.I.N., demonstrating a higher level of intelligence than the others. #15 was referred to indirectly as "Bison's right hand". Shadaloo also had a family murdered in Korea. The only member of that family who remained alive was Juri Han, driven by anger, she join S.I.N. #15 gives her the Feng Shui Engine, deciding she can be used to carry out missions for their own dark desires. After Bison's apparent demise at the hands of Akuma, #15 takes the name Seth and makes his own attempt at world domination, beginning with the announcement of a new tournament to bring out Ryu and to gain his Satsui no Hadou to make S.I.N far more powerful without letting most of his workers know, but Juri has a plan of her own and, apparently aware that Bison has survived, tries to pit Bison and Seth against each other in revenge for her parents' murder. Bison takes the bait and returns, his soul transplanted to yet another new body (again not as powerful as his Alpha days). Though his scientists try to dissuade him (their reasoning being that, in time, a new body could be created that could hold the Psycho Power in its entirety), Bison chooses the weaker body instead of remaining dead any longer, stating that he never imagined that Seth would go so far and it will only be a matter of time before Bison would inhabit his body(meaning Ryu), anyway. Bison then takes part in Seth's new World Warrior tournament, completely incapacitating his opponents in the qualifying rounds.

Bison eventually reaches Seth's S.I.N. headquarters at the head of the remaining androids, attacking Seth for losing his mindless servitude to Bison, which makes him useless. Seth protests that he had almost rebuilt Bison's empire, which had fallen into decline since the second World Warrior tournament; however, Bison counters by saying that everything that has happened has, in fact, been part of Bison's plan. Standing over the helpless Seth, Bison is suddenly confronted by Juri, whose plan to have the two destroy each other has failed as Seth did not put up enough of a fight. She threatens Bison, who is unimpressed, and though the resultant fight (if any) is not shown, both seem to survive as both are seen later.

Meanwhile, another android which had been fighting Abel shows signs of also developing self-awareness like Seth, and Bison promptly destroys it, remarking that Abel has grown since an unspecified last meeting. His exact relationship with Abel is unknown; however, it is implied that Abel was somehow part of the experiments that created the androids. On his way out of the facility, Bison ambushes Rose, also at the S.I.N. headquarters. Remarking that she owes him something, Bison incapacitates her and threatens to take it back "with interest". As Bison reaches his jet, however, he is confronted by Guy, who threatens to destroy the jet if Bison does not hand her over. Apparently in a hurry, Bison acquiesces and relinquishes the unconscious Rose.

  • In this game, M. Bison constantly references his lines from the infamous Street Fighter live action movie, as well as the equally infamous american cartoon:
    • Bison's taunt: "For me, it was a Tuesday". Curiously, this game literally was released on a Tuesday.
    • Bison vs. Blanka: "I have done many things, but I'm certainly not responsible for creating something as ridiculous as you."
    • Bison vs. Chun-Li: "All you women ever do is whine! I killed my father too, and you don't see me crying about it!"
    • Bison vs. Guile: "What's the matter, Guile? Came here expecting to fight a mere mortal? Bison is far beyond you!"
    • Bison vs. Hugo: "Bwa ha ha ha! I can hear the sound of your bones breaking! Yes! This is delicious!"
