Streets Of Rage Wiki

Mr. X (Mr.Xミスターエックス Misutā Ekkusu) is a recurring villain in the Streets of Rage video game series, being the titular main villain of Sega Genesis Trilogy Saga. In all games, he is depicted as a mysterious and wealthy crime lord. His Syndicate organization plans to bring order of crime to Wood Oak City. His true identity is unknown.


Mr. X was a middle-aged Caucasian man with fair skin and long black hair. He wore an olive-green two-piece suit over a white dress shirt and a red tie. In the first game, he was armed with what appeared to be a generic machine gun, which he replaced with a Tommy Gun in the second game.


He was a very enigmatic crime lord, and little is known about his personality. It seemed that he respected the strength of others, as he compliments the heroes when they make it to his hideout and offered them a chance to join his syndicate. He was also very vindictive, as shown in the second game, where he sought to avenge his first defeat by kidnapping Adam Hunter.

Streets of Rage / Bare Knuckle[]

In the first game, Mr. X's Syndicate Crime Organization has taken over the city and the police force. Though he enlisted powerful crooks such as Antonio, Souther, Abadede, Bongo and Mona and Lisa, he ultimately could not stop Blaze FieldingAxel Stone and Adam Hunter's efforts to defeat his organization and foil his plans.

After the three defeated all of Mr. X's henchmen, they went to his lair and defeated him in a final showdown. Before the showdown, he asked the three if they wanted to join him, but they refused, knowing what was right. The good ending shows Mr. X knocked out by Blaze, Axel and Adam and then shows the trio enjoying the peaceful city they have created by defeating Mr. X, who is seemingly killed at the end of the conflict.

There is also a bad ending, which can only be achieved by reaching the end of the final round with two players. When he asks if the players want to join his organization, both players must disagree with each other. The one that said 'yes' must then defeat the one that said 'no', and then, the surviving player must change their mind, refuse Mr. X's final offer, and defeat him alone. The bad ending shows the player character becoming the new leader of Mr. X's criminal organization.

Streets of Rage 2 / Bare Knuckle II[]


After being defeated in the first game, it's revealed, a year later, that Mr. X survived the fight against the three vigilantes. He plots his revenge against the heroes by ordering Shiva to kidnap Adam in order to bait Axel and Blaze. Fortunately, the two heroes find help by teaming up with Adam's younger brother, Eddie "Skate" Hunter, and a wrestler and Axel's friend, Max Thunder.

It is revealed that Mr. X plans to use his massive wealth to invest in robotics for warfare, as shown by the prototype robots he employs against Axel and his friends.

Once making it to Mr. X's lair, the four heroes must fight his first lieutenant and right-hand man, Shiva, before taking on the crime lord himself. Unlike the first and third games, there is only one ending, where Mr. X is once again defeated, and Adam is freed.

Streets of Rage 3 / Bare Knuckle III[]

Mr. X returns once more, with the story of the differing depending on the version. In the North American version, he plans to replace the world leaders with robots, while in the original Japanese version, Mr. X's plan involved an explosive substance known as Rakushin. He carries his plan out with both new and old henchmen, as well as a scientist named Dr. Dahm. Mr. X continues to use his wealth to invest in robotics and arm the Syndicate, creating a mass production of combat robots and even a robotic duplicate of Axel.

Adam sets off to diffuse bombs that have been planted throughout the city while Blaze, Axel, and Skate team up with the former Syndicate scientist, a cyborg named Dr. Gilbert Zan; in the Japanese version, it's revealed that Zan was responsible for discovering the Rakushin element.

There are four possible endings:

  • The Worst Ending (nicknamed by fans as "Incomplete Ending") occurs if the player is on Easy Mode. While the Japanese version allows the player to go through all seven levels on Easy Mode, the North American version of Easy Mode ends at the fifth level, after the boss fight against Mr. X's robotic imposter. The ending has Robot X taunting the player and encouraging them to play through the game on a harder difficulty, claiming that they need to do better than that to defeat Mr. X.
  • The Second Bad Ending (nicknamed by fans as "Impostor Ending") occurs when the player fails to save the general in the sixth stage. This results in playing an alternate Stage 7-B where Shiva is the final boss. After defeating him, Zan vows that he will find and destroy Mr. X. The regular Stage 7-A has Dr. Dahm appearing as a sub-boss fight, before the player can finally confront the real Mr. X. Having barely survived his first two defeats, all that is left of Mr. X is his brain, now preserved in a jar, that fights the heroes by controlling a robot called Neo. X (known as "Neo. X" in the Japanese version).
  • The Third Bad Ending (nicknamed by fans as "Tragic Ending") plays if the player saves the general in Stage 6, but runs out of time when defeating Neo. X. The ending has the robot destroying the jar containing Mr. X's brain. Before dying, Mr. X detonates the bombs planted all over the city. Adam manages to save the heroes, but their reputation has now been severely damaged, as the bombs they failed to diffuse have destroyed buildings and killed countless innocent civilians.
  • In order to get the Good Ending, the player has to both save the general in Stage 6 and defeat Neo. X in time. While Mr. X meets his end like by the hands of his Neo. X, Adam now succeeds in defusing all of the bombs before rescuing the four heroes. It is then revealed that after Mr. X's headquarters was destroyed, the heroes all went their separate ways, now that Mr. X was no longer around to terrorize anyone.

Streets of Rage 4 / Bare Knuckle IV[]

Since he was killed in third entry, Mr. X doesn't make a return. His children, the twins Mr. Y and Ms. Y, carry on his legacy in reviving his crime empire, using his wealth to terrorize the Wood Oak City.

References to Mr. X are seen through the game in the form of portraits located in Y Tower and Y Island.

During Stage 8, the player can access the last hidden retro level, which is the final battle against Shiva and Mr. X from Streets of Rage 2.

During Stage 12, the player can fight Mr. X, in his first Streets of Rage 4 version, by destroying a cursed arcade cabinet found inside the Y Castle Fortress. This can only be done on Mania+.

In the DLC Mr. X Nightmare, Dr. Zan builds an AI program from the remnants of Mister X’s brain, that simulates every kind of danger the heroes could be facing; this canonically takes place after Axel and his friends have defeated the Y Twins. In the simulation, the player can fight both Streets of Rage and Streets of Rage 2 versions of Mr. X, as well Robot X.

In the three-part Streets of Rage serial in Sonic The Comic, it is revealed that the original Mr. X was killed after failing to terminate Axel, Blaze, and Max, and that a new Mr. X has taken his place. The serial ended with a cliffhanger ending where the new Mr. X promised to "recoup his losses" by killing the heroes. While he doesn't appear in Project X Zone 2, his soul inhabits Break saying Shadaloo is no more and plans to revive the Syndicate, but is stopped by Axel and his Shinra allies, though not before he warns Axel that the Syndicate would never die, foreshadowing Streets of Rage 4 and his children...
