Mario is one of the three main characters and a plumber who lives in the castle. He usually hangs out with his best friend SMG4 and his new friend OnyxKing67.
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.
