Appeared exactly once in Mario's Perfect Documentary. He looks like Mario but with different colored clothes. His full name is Super Meme Guardian 5, but honestly, seeing as he only appeared once, he's just an extra.

He resembles Mario but with different colors. He appears quite often and is a supporting character. Since he's identical to Mario except for his clothes, he's basically a second Mario.

A villain from SMG4 Season 1. He was killed by Mario's King Bob-omb but SMG3 brought him back (damn it). He carries a knife and his appearance is reminiscent of Fire Mario, but he doesn't shoot fire.

He turned evil because Mario ruined his birthday party. He tried to kill Mario but kept getting caught by the police. Eventually, he turned good again after Mario gave him a cake.

Basically a flashy, glamorous Mario. Like Subeom, he looks so much like Mario that it's almost awe-inspiring.

Full name is Super Meme Guardian 4. Unlike Smg5, he's the protagonist who does things like stopping Eldritch SMG0. He's one of the weakest, but it's impressive he's still alive. He loves computers and has a pet called Beeg SMG4.

He loves bombs and is actually strong, unlike a certain someone. He has a pet Eggdog. He used to have an Ugandan Knuckles named Terrence, but he died and Smg3 seems to have forgotten him now. He owns his own cafe.

A Canadian YouTuber who had some controversies but seems to have returned. He is a character from the early days of SMG4.
