Street Fighter Alpha/Characters/M. Bison

Click here for more information about M. Bison's other fighting game appearances.

During the events of Street Fighter Alpha, Shadoloo came to the attention of Interpol, which sent Chun-Li (an operative with a personal vendetta against the crime lord, who had killed her father) to thwart Bison's plans. Chun-Li and M. Bison eventually confronted each other and battled. M. Bison defeated Chun-Li and then escaped on his helicopter while mocking her and promising to kill her in the same manner he killed her father if she confronts him again. During the events of Alpha or Alpha 2, M. Bison also came into conflict with Rose, a mysterious woman who wielded Soul Power, the opposite of Bison's Psycho Power. This fact and the fact that her quest was to stop any and all of M. Bison's evil plans indicate the intricate connection between the two, and would later be revealed in Street Fighter Alpha 3.

Most likely during the events of Street Fighter Alpha 2, the Psycho Power began 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, but that body, Cammy, escaped from Shadoloo's conditioning. M. Bison then turned his sights to Ryu, one of the most powerful fighters in the world, and the personal nemesis of Bison's former underling, Sagat. Bison defeated and captured Ryu and subjected him to intense psychological conditioning; when Sagat objected, M. Bison turned Ryu on him, telling him he could finally have his rematch. While Sagat battled Ryu, Ryu's friends Ken and Sakura fought M. Bison. With Sagat's urging, Ryu comes to his senses and forces M. Bison to retreat to the Psycho Drive, which restored his power.

In Street Fighter Alpha 3, USAF officers Charlie and Guile are on a mission to stop the dictator from using his new creation, a satellite (featured in Street Fighter Alpha 3), which can enhance his Psycho Power abilities. Guile and Charlie are joined by Chun-Li, and the three of them battle M. Bison. In order to take down Shadoloo's leader, Charlie keeps fighting him while the base is set to explode, and eventually sacrifices his own life. M. Bison's soul, however, ended up surviving the explosion and took control of Rose. It is revealed that, while trying to master Psycho Power, 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 stayed inside of Rose's body until his Shadoloo scientists could forge a new body for him, the body seen in Street Fighter II. This body, however, was much weaker, since, having inhabited his "good side"'s soul for a period of time, he retained both his good and evil energies as he transferred to his new body, thus making his Psycho Power considerably less effective.
