SuperMarioGlitchy4 (SMG4 for short) is one of the two main protagonists (alongside Mario) of the SMG4 series. He served as a major character in Seasons 1 and 2 before becoming a main character. He serves as one of the three main protagonists of the Waluigi Arc (alongside Mario and Wario).

He is predominantly a Super Mario 64 machinimist, as well as Mario's closest ally (rival in the War of the Fat Italians series), the de facto of his gang, and the arch-enemy of SMG3. He also used material from MinecraftGarry's Mod, and other media. SMG4 devoted a lot of his time to making these videos, usually uploading a new video every weekend, and sometimes accepts works such as fanart from his channel's viewers and subscribers. In his videos, he often used quotes, music, and stuff from other famous YouTubers like PewDiePie and Smosh as well as from movies, video games, memes, or TV shows. He is also the oldest original character in the series.

SMG4 heavily practiced self-insertion, as he usually appeared as a blue and white lookalike of Mario. From his debut, SMG4's character had been passionate and protective of his work; that aside, he seemed to play the sane man who is often annoyed or shocked by Mario's crazy, flamboyant idiocy. Despite this, they were friends in most videos, especially in the recent ones.

In The YouTube Arc, SMG4 was sent to the Internet Graveyard in SMG4: Deleted due to SMG3 altering the events of his debut in Super Mario 64 Bloopers: Account Loss, having Mario kick him out. However, he and his friends were rescued by Mario in SMG4: A Totally Normal S̷͍͖͉̙͚͎̑̃̿͑̆̇̚͠M̸͇͇̦̮̌̿Ğ̴̫̗̖͎͔̳4̶̞͇̰̎̀́̚ Episode. By the end of SMG4: War Of The Fat Italians 2020, he and his friends defeated SMG3, and have Susan Wojcicki banish him to the Internet Graveyard to feel what it is like to live in this horrible place that he and his friends have.

Personality and Traits

Unlike Mario, SMG4 is the sane, sophisticated, and level-headed of the group and has to bear the burdens of other people's stupidity, especially as he often lacks patience with Mario's antics, getting annoyed when Mario acts like an idiot when he or someone else needs his help the most, especially when his stupidity makes the problems worse than they are; however the two remain good friends regardless. Even with his intelligence, he has occasional idiotic moments himself as he was scammed by Wario and Waluigi at one point. SMG4 does get caught up in all kinds of adventures with his friends and tries very hard to strategize and keep the peace, even if it doesn't always work out, especially with his friends', and at times his own flaws getting in the way.

SMG4 seems to be very anti-social, as he prefers doing his own thing, like creating memes and funny videos over spending time with his friends. He is very protective of his work and doesn't take kindly to anyone tampering, ruining, or even touching it, which will set him off.

Nonetheless, SMG4 really cares for his friends and will put his work aside for the greater good and join them on their crazy adventures whether for fun or stopping various villains from bringing their plans to fruition. He also disapproves of Mario abusing his younger brother Luigi, although he doesn't interact with him very often. While he tends to be cold towards Luigi, he shows sympathy for him being the butt of several misfortunes other than being forgotten and beaten up.

Physical Appearance

SMG4 has an appearance very similar to Mario, with white gloves, brown shoes, a black mustache, brown hair, blue eyes, and a round nose. The main difference is that he wears a blue hat with a red "M" on it, a blue shirt, and white overalls with yellow buttons.


  • Unlike Mario and Toad, SMG4 really hates spaghetti. Rather, he prefers rice and chicken
  • SMG4's signature pose is the "Facepalm" which points to his frustrations with the stupidity of his friends.
  • His archenemy is SMG3, which is similar to Mario's arch-enemy being Bowser.
