M. Bison, also known as Dictator, is a video game character created by Capcom. First introduced in Street Fighter II: The World Warrior, he is a recurring character and villain in the Street Fighter series of fighting games, acting as one of the series' primary antagonists. A would-be world dictator and megalomaniac, M. Bison's ultimate ambition is to control the world's governments through his covert crime syndicate, Shadaloo (shiyadoru, Shadoru, sometimes spelled as "Shadoloo", "Shadowloo" or "Shadowlaw"). He serves as the host of Street Fighter II's fighting tournament and is the last opponent fought in the game.

In some versions of Street Fighter games, the player will face an alternate version of M. Bison, usually as a computer controlled opponent in the game's single-player mode. In Street Fighter Alpha 3, a more powerful form of M. Bison with stronger abilities and fewer weaknesses appears as the final boss for every character except Evil Ryu, who fights Shin Akuma, and M. Bison himself, who fights Ryu. Should the player lose and not continue, an edited version of M. Bison's ending will play, and the game will end. There also are some minor differences with this form aside from damage output. His fierce punch attacks send out a wave of energy and his Psycho Crusher Super Combo fills the whole screen with a devastating streak of blue flames. This improved Psycho Crusher is much faster and stronger than its normal counterpart, cannot be blocked in the air, and inflicts severe damage even when blocked; it is the most powerful move in the game. The player is also able to choose this version of M. Bison as a 4th ISM, dubbed Shadaloo-ISM (or S-ISM), in the console versions of Street Fighter Alpha 3, by choosing Bison with the select button.  In Street Fighter EX2 Plus for the arcade and PlayStation, another version of Bison appears called "Bison II" (or "Vega II") as a secret final opponent in single-player mode. If the player defeats the regular version of Bison at the end, Bison will resurrect himself as Bison II and challenge the player. Bison II can be distinguished from the regular version of Bison by the white-colored outfit he wears back in EX2, and the background which changes to a colorful light stream coming out of the floor in a pure black room. In EX3 he sports a black uniform, gold plates, and has orange-tinted skin. Like Alpha 3 M. Bison, the player cannot continue after losing against Bison II in EX2.  In Street Fighter EX3, Bison II returns as a playable secret character. His move set is identical to that of his normal counterpart, with the exception of two additional Psycho Cannon attacks.  A third, computer-controlled only version of the character, known as "Shin-Bison" (or "True Vega"), is also included in EX3. Shin-Bison appears with pale, purple-tinted skin, blue-green plates, and a white uniform. In addition to an overall speed increase, he has an infinite amount of SC energy, the ability to cancel most of his attacks, and a new Knee Press Nightmare Meteor combo where he creates three copies of himself, one above and two beside him, which gives the move a massive range boost. This incarnation is considered to be his most formidable.
