Fan Casting FightingMario54321 in SMG4

FightingMario54321 is one of SMG4's close friends. He was a Super Mario 64 machinimist himself before quitting in 2015. Since then, most of the newer videos on his channel were uploaded by his brother from the period of 2015-2019, although he did return somewhat in 2020 where he usually uploads videos he posts on Twitter. Good at fighting, – hence his pseudonym – FightingMario54321 is somewhat the tough guy, and acts as one of the few sane characters. While not appearing as much as he used to, he is still a friend of SMG4 and Mario, as well as a member of the R.M.K.P.D.
