MCGustavo (formerly known as MejiaCantilloGustavo), or MCG for short, is a minor youtuber in the SMG4 series.

He is a friend of SMG4. He used to make Super Mario 64 and Roblox Bloopers but those two have now been discontinued. His channel is now going through an experimental stage but aims to create parodies and X cliches with fan bases.

He first appeared in the video "Super Mario 64 Bloopers: SMG4 VS SMG3", along with FightingMario54321, in which he helps track down whoever is copying SMG4's videos.

Color code

Here is MCGustavo's color code (Note that this is not a hex color code):

  • Red overalls,
  • Blue cap, harms, and shirt,
  • Yellow gloves,
  • White shoes,
  • Same face as Mario, Luigi and a lot of other guys,
  • Same brown hair as Mario, Luigi, and many other guys.


Since the video "SMG4 VS. SMG3", MCGustavo appeared a lot in SMG4's videos, but he has decreased in appearances since 2014, along with the other YouTubers/Super Mario 64 Machinimists, due to SMG4 decided to focus more on the Mario characters than the YouTubers to make his bloopers funnier than before. However, as the other SM64 machinimists, MCG still makes cameo appearances in SMG4's videos.


  • He has over 1,200 subscribers.
  • He has over 75 videos currently. (Most of them are Unlisted)
  • He makes great toilet paper.
  • Mario called him Marijuana.
  • He appeared in the 2013–Present-day bloopers with recurring cameos.

  • In War of the Fat Italians 2015, MCGustavo suggests a challenge to launch a Waluigi Launcher the farthest via twitter.
  • He joined YouTube on October 10, 2010.
  • In 2011, Nintendofan997 wanted people to be in his SM64 movie, Zombie invasion. MCG just so happened to be one of the first people that commented and so he listed his color code. As promised, MCG is featured in part 3 in Zombie invasion but surprisingly made it into SMG4 VS. SMG3 as a surprise gift.
  • Although he likes peanut butter, he is allergic to it as it does something to his face.
  • His former youtube name is MCGYouTube.
