X (not to be confused with Nintendofan997) is a minor character in the SMG4 series.

He is a villain who appeared often in the earlier seasons.


Super Mario 64 Bloopers: Enter X

He steals Mario's body and takes full possession of it, controlling his brain. Then, X proceeds to take over the world by going on a killing spree, defeating various enemies, bosses, and other creatures. Mario eventually finds X within his memory, who tells him that the only way for Mario to regain control of his body is to find a special key from Bowser so he can press the Abort button. Later, Mario returns to X and asks him where the door for the key is. X then makes the mistake of unknowingly telling Mario that the door is in Bowser's Secret Lair, realizing this just as Mario leaves. X orders Luigi, Peach, and Yoshi as guards to stop Mario, but they all fail on him as Mario unlocks the door and pushes the Abort button. With X's plans for world domination foiled, he ends up getting puked out of Mario's body and is locked up in jail afterwards.

A Murder Without Peach

X makes his next appearance in Super Mario 64 Bloopers: A Murder Without Peach, where he murders a guest at Mario's party. Mario and SMG4 discover and attempt to stop him, but they fail as X escapes from the castle. Later, X calls Mario and SMG4 and tells them to meet him in the city. When the two arrive at X's location, X reveals his identity and states he was the murderer and that he wants revenge for what happened to him in Super Mario 64 Bloopers: Enter X. He claims there is no way for Mario and SMG4 to escape, but they head for the door with no traps to stop them. However, before they can leave, X taunts Mario by saying "spaghetti sucks", at which point Mario proceeds to attack him. X escapes in his car, but Mario and SMG4 catch up to him in their own car. After a hot pursuit, the three suddenly end up on top of a skyscraper. X tries to push Mario off the skyscraper, but SMG4 accidentally pushes both of them off with his car. Mario and X survive the fall, but X tries to escape only to crash his car, killing him in the process. Afterwards, his corpse is later stuffed into a toilet back at the castle.

SMG3's Plan to Destroy SMG4 Because He Felt Like It

X makes his third appearance in SMG3's plan to destroy SMG4 because he felt like it. He and other dead villains from SMG4's videos are brought back to life by SMG3 as part of his plan to kill SMG4. However, unlike his previous two appearances, X is not nearly as involved in this episode compared to his previous ones, instead only being limited to a few lines of dialogue throughout the video.

Ssenmodnar 10 (350k Apocalypse Special)

X appears in a bit where Dr. Eggman is explaining how he looked up to his grandfather as a child for all his great accomplishments. X interrupts and reveals that Eggman's grandfather was actually his mother, proceeding to show him images in a file folder of his mother. Eggman responds in shock initially and then replies: "damnnnn!"

SMG4 Movie: 10 Year Anniversary Special

X is one of the many recolored Mario controlled by SMG0. He was blocking SMG1 and SMG2 until Bob and Fishy Boopkins started to sing a song that distracted them long enough to let SMG1 and SMG2 pass. When Zero was defeated, he returned to Bloopersville and is seen in the background.


X wears an all-black outfit, with two rows of single brass buttons and white gloves on his hands. When he takes control of Mario, his color scheme is the same as Mario, with the exception that his eyes are now black and soulless, identifying that X has taken full control of his victim.


Being a character with a few major episodes, X appears to be a standard, stereotypical villain, albeit slightly smarter. In later appearances, X appears to have been redeemed, now explaining to Baby Luigi that he should never walk the street alone.

Powers and Abilities

Possession- X can steal and take control of a persons body by entering their brain, but the victim can also regain control over him by finding and getting rid of X within their memory.
