SMG1! is the name! doing...umm..bad stuff is my game..
SuperMegaGangsta1 (also known as SuperMarioGlitchy1 and SMG1) is the shadowy leader of the S.M.G club, dressed exactly like SuperMarioGlitchy4 and the other SuperMegaGangstas. His sole appearance was the blooperS.M.G Club, where he ripped off SMG4's style to make his "evil" club more popular. In the end, Mario and SMG4 dismembered him via self-destroying the club, nicknaming him SuperMarioGay1. The song Blood Sugar by Pendulum appears to be his theme, and he appears to hate songs by Justin Bieber.
Desperate for attention, He stole SMG4s whole design just to make people go to his club because it looked cool but overall he's pretty normal, besides Him having a self destruct button his club.
