Throughout the series, several characters — including, Guile, T. Hawk, Cammy, Rose and Chun-Li — have their personal vendettas against M. Bison and have entered the tournament in the hopes of facing him personally, while M. Bison routinely sets his eyes on the series' main protagonist Ryu in order to either acquire his power or recruit him for his cause. M. Bison wields an inherently evil energy known as "Psycho Power", in contrast to Ryu and Ken's "Hadou".

In a variety of media, Bison has been portrayed by Raul Julia, Neal McDonough and Silvio Šimac and voiced by Tom Wyner, Richard Newman and Gerald C. Rivers. Julia was nominated for a posthumous Saturn Award for Best Supporting Actor for his performance.

Conception and development In Japan, the character is named , derived from the star of the same name. However, during localization of Street Fighter II for the English language market, Capcom's North American branch felt that the name did not sound threatening enough to North American audiences for the game's final boss, and thus was more suitable for the Spanish cage fighter. At this same time, another concern arose that the name of another character, Mike Bison, conceived as a pastiche to real-life boxer Mike Tyson, would be a legal liability for Capcom. As a result, the characters' names were changed, and the game's final boss was dubbed M. Bison for international appearances of the character. Though the "M" originally stood for "Mike" in Japan (for the boxer character), Capcom has never explained what it stands for in Western releases, calling it "part of the character's mystery". The story of Street Fighter 6 acknowledged this change within the context of its narrative, claiming that all three names were aliases that Shadaloo's leadership operated under to protect their true identities.

Although his nationality is never given, he is usually depicted as fighting in or around Thailand, or in fictional locations such as Point 48106.

When developing Street Fighter II: The Animated Movie, it was decided to give him a more muscular appearance, rather than have him resemble "a middle aged man", while his face was modified to appear somewhat demonic. This appearance was later carried onto the Street Fighter Alpha series, featured as his original appearance before the Street Fighter II series.

The first source of inspiration for M. Bison's design came from the character General Washizaki, one of the main villains of the popular martial arts manga Riki-Oh.月刊ゲーメスト10月号増刊『ストリートファイターII』p83。『COMPLETE FILE STREET FIGHTER II』P59(発行:カプコン、発売:朝日ソノラマ・1992年刊)。 Additionally, Yasunori Katō, a fictional character appeared in the Teito Monogatari series and other productions such as the Yokai Monsters, served as another inspiration source for M. Bison.Timothy Blake Donohoo, October 27, 2022, Street Fighter's Greatest Villain Was Inspired by a Spooky Japanese Horror Novel, Comic Book Resources

For Street Fighter 6, Takayuki Nakayama and the rest of the staff began to design M. Bison after the main cast was completed. His return to the franchise was planned for some time, and there were many voices on the staff calling for Bison to return; producer Shuhei Matsumoto, for instance, has been a regular Bison player since Super Street Fighter IV. Nakayama noted that the team planned to portray Bison in a different light for this entry, since the character JP is the villain for this installment; his arcade mode delves further into this new characterization. His gameplay was also altered for his latest appearance, with his supernatural techniques being removed in favour of a more hand-to-hand approach.

Appearances Street Fighter series Bison first appears in Street Fighter II: The World Warrior as the final computer-controlled opponent in the single-player mode at a temple in Bangkok, Thailand. He became a playable character from Champion Edition and onward, while maintaining his position as the final boss until Super Street Fighter II Turbo, in which a hidden character named Akuma defeats Bison and challenges the player as an alternate final boss. The storyline through the numerous versions of Street Fighter II characterizes Bison as the leader of a criminal organization called "Shadaloo" who sponsors the World Warrior tournament. Bison later appears in the Street Fighter Alpha trilogy, a prequel to the Street Fighter II series. In Street Fighter Alpha: Warriors' Dreams, Bison appears as the final boss for certain characters and a hidden playable character available via a code. Street Fighter Alpha 2, has Bison featured in this game as a playable character. In Street Fighter Alpha 3, a powered-up version of M. Bison serves as the final boss of the game. Several revelations are made in this game, including the fact that Rose, not only being former fellow disciple of Soul Power, but also a good half of Bison's soul, while Cammy is a female clone of Bison and an unknown individual. Bison is revealed to be dying due to the strain of Psycho Power on his body and the only thing keeping him alive is his Psycho Drive, which brings him to search for Ryu, whose body he has deemed worthy of possession. Bison fights Ryu but is defeated. Bison transfers his soul into Rose's body before dying.

The main villain of Street Fighter IV is Seth, an android previously created for Bison's soul to inhabit but went rogue and usurped the leadership of S.I.N., a subsidiary of Shadaloo. It is later revealed, however, that Bison is actually the true mastermind behind the game's events, and was secretly manipulating Seth to further his own agendas before revealing himself again. In the near climax of the game, however, Bison tries to capture Rose again, but was forced to retreat and leave her because of Guy's interference. Bison appears in Street Fighter V. Shadaloo enacts a plan known as "Operation C.H.A.I.N.S." in which seven artificial satellites known as the "Black Moons" are constructed to cause various cities around the world to lose power, thereby creating commotion which fuels Bison's Psycho Power due to negative emotions. When the plan is ultimately foiled, a resurrected Charlie Nash sacrifices himself to weaken Bison, leaving Ryu to defeat him one last time. After his presumed death, a ghost empowered by Psycho Power of himself called Phantom Bison is mostly shown haunting both of his former vessels, Falke and Ed.

Bison returns in Street Fighter 6 via downloadable content, where he previously was revealed to have bestowed Psycho Power to JP prior to Shadaloo's downfall. Bison's depiction is a departure from previous appearances, and he has developed amnesia. Bison also reveals to have saved a dying male horse by imbuing him with Psycho Power at Nayshall. The amnesiac Bison is later revealed to be one of the original Bison's clone bodies, who absorbs Phantom Bison and decides to take up leadership of Shadaloo once more.

Other games Bison appears in Street Fighter: The Movie, a 1995 video game adaptation of the 1994 film. The game looks similar to early Mortal Kombat games, due to each character being represented by digitized sprites of the film's actors. Bison's fight animations were performed by Australian stuntman Darko Tuscan. Film clips of Juliá as Bison are included within the game's cutscenes.

In other media Live action

Raúl Juliá played Bison in the 1994 live-action film adaption of the series. Julia perceived Bison in the same vein of villain as Richard III, and approached the role with a Shakespearean tone. In the film, Bison is a British psychopathic drug kingpin and notorious military dictator who controls not only Shadaloo (here depicted as his hostile dictatorship instead of his organization) but also the drug industry with an iron fist. One of his goals in the film is to produce supersoldiers to take over the world and establish a new order known as "Pax Bisonica" using his drug profits. His ambitions have led to a war in Shadaloo with the Allied Nations (AN), led by Colonel Guile, the movie's main character who has been sent to place Bison under arrest for his war crimes. In the film, while Ryu plays a vital role in Bison's downfall by helping to lure Guile to Bison's base, Bison and Ryu do not fight, though at one point, Ryu attempts to fight Bison alongside Ken, Chun-Li, E. Honda and Balrog. In the climax, he fights Guile and very nearly kills him with his uniform's built-in electromagnetism (the film's stand-in for Bison's Psycho Power), but he is defeated when Guile kicks him into his gigantic monitor screen and leaves him to die when the base explodes. A post-credits scene only available on the home-video release shows Bison resurrected through a solar-powered life support machine.
