MarioMario54321

MarioMario54321 (often shortened to MM54321,or MM) is a popular Super Mario 64 machinimist and blooper-maker who makes appearances in SuperMarioGlitchy4's videos and sometimes rivals with him. MarioMario54321 is friends with Starman3, SMG4, Lilyncookies, and LuigiGame2.

Due to SMG4's decreased focus on including other YouTubers, machinimists and YTR members in his bloopers, MM54321's presence in recent videos of SMG4's are mostly limited to cameos. MM54321 and other machinimists still make frequent cameo appearances in the Ssenmodnar series.

Color code
MarioMario54321 made himself a color code with YoshiElectron's generator. Following is a list of the modified colors:
 * White overalls

 * Grey gloves
 * Blue shoes
 * Yellow face
 * Brown hair

Appearances
MarioMario54321's debut in SMG4's bloopers was The Blooper Competition as the main antagonist. This would change though. MM would go on to reappear in several other bloopers, mostly in 2012. But, along with the other YouTubers and friends of SMG4, he decreased in appearances since late 2012, and on 2014 his appearances are limited to cameos, usually in the Ssenmodnar videos. He totally disappeared just before 2015 for some reason, and didn't even appear in Ssenmodnar 10 (350k apocalypse special) while he had appeared in all the other episodes of the Ssenmodnar series only to reappear again a few months later.
