While obnoxiously stupid at times, Mario almost acts like a normal person most of the time.
Mario, in similar contrast to SMG4's Mario, acts dimwitted, reckless, and profane. However, in less frequent moments, he can act intelligent and cunning, as shown taking his driver's test, where he swaps his test with Starlow's, managing to move on to the actual driving.
Mario is an Italian that has a black mustache, brown hair, a red cap with an M, a red long-sleeved shirt, blue overalls with yellow buttons, brown shoes, and white gloves.
Debuting in 2014 in SM64 Bloopers: A Retarded Welcome, Mario since his debut has always hung around with OnyxKing67 and SuperMarioGlitchy4, involving himself (and usually his friends) in various bloopers.
