The Golden Rock This is a featured article!

That means it's considered to be one of the best articles the SuperMarioGlitchy4 Wiki has to offer.

You can still edit the article, but please be cautious when doing so. Thank you.

Template:Infobox Character Nintendofan997 (formerly known as Xboxfan997 or X or sometimes Xboxfan), is SuperMarioGlitchy4 and FightingMario54321's best friend and also has his own YouTube account.

Nintendofan997 used to be one of the most common characters, but now makes minor appearances in SMG4's videos as well as making SMG4 appear in his own videos. He has a evil doppelganger called Nintendofan998, except he's called Xboxfan996 or Nintendofan996 SMG4's videos, for some reason.

Color code

Nintendofan997's color code looks similar to MarioGame2222's, due to the colors used for the cap, arms and shirt, and for the overalls:

  • Green overalls,
  • Blue sky cap, harms and shirt,
  • Black gloves,
  • Brown shoes (like Mario, Luigi and a lot of other guys),
  • Tanned face (slightly darker than regular, as you can see in the picture at the top right corner of this article),
  • Brown hair (like Mario, Luigi and many other guys).

His eyes sometimes appear green instead of blue (the regular color).


Unlike the rest of the characters, X appears to be more calm and compassionate than the rest. While he does show discomfort towards the shenanigans around him(even towards his closest friends), he rarely ever loses his cool.

Seaside Stupidity Part 1 shows him to be rather cowardly, as he decides that it's every man for themselves after a sea monster ends up causing the cruise ship he was riding on (along with many other passengers) to sink. He later attempts to persuade A.S Swipe to kill Mario instead of him, only for Mario to retaliate by saying that he should kill X instead for being a side character.


Nintendofan997 seems to have a future sight ability which he uses unwillingly to detect danger/dark omens. How he obtained this power is unknown. When he uses this power he seems to experience a lot of pain.

It's implied in the video "The Crazy Fighters" that he also has the power to shoot lasers.

He carried guns with him during early videos as he came from the zombie era. (Mario stole one prior to the events of Crystal Funhouse)


Nintendofan997 has only one counterpart in bloopers: Nintendofan998 (or Xboxfan998), his evil doppelganger, who is called "Xboxfan996" in SMG4's videos for an unknown reason.

  • He rarely makes videos now, but he still post comments and subscribes.
  • He was formerly known as Xboxfan997 but he changed his YouTube channel username.
  • Despite his name being different for quite some time, he's still called "X" in SMG4's bloopers.
  • According to him - In the episode "Crystal Funhouse" -, AustinDawgyDawg and GageDawg are better fighters than FightingMario54321. However, this is just his opinion, so it may not be true.
  • In the video "Two Great Friends!", he has two "roommates" (or "housemates" as he said) staying at his house: Ben, a mentally unstable yellow Toad wearing sunglasses, and the Princess Daisy.
  • In this same blooper, he has a Ford/Shelby Mustang car.
  • In the episode "Cooking with Bowser and Mario 2!", he sells burgers.
  • In 2014, he only appeared in cameos for a while, but returned as a main character in the video "War of the Fat Italians 2014 (200k special!)".
  • Xboxfan997 acts as the host in the video "War of the Fat Italians 2013", though he refers to himself as "Xboxfanguy".
  • It is implied he uses drugs, as in the video "War of the Fat Italians 2013" when Mario and SMG4 go to him to find out who wins, he says "The drugs are over there! Don't hurt me!", implying he is a drug-user.
    • This is also implied in the video "The Imposter", as SMG4 states he is on crack again when the imposter (X) is chasing him.
  • He has over 10,347 subscribers
  • He and SM64 were the only non-fictional Youtubers to be infected by the T-Pose Shroom.
  • While Nintendofan997 is called "X", he is not to be confused with X, a villain who stole Mario's body in the episode "Enter X".
  • He has appeared in every War of the Fat Italians as the judge except the 2018 edition, due to being T-Posed. Waluigi takes over the judge role instead.
  • His favorite SMG4 video is SMG4: Mario waits for pizza.
