He is SMG4's evil doppelganger who is first discovered trying to copy SMG4's videos, and had attempted to kill him ever since. He (and Wario) were the people responsible for turning Waluigi back to normal at the end of WOTFI 2018. After the T-Pose incidents, he retired from villainy to start a therapy television series called Dr. SMG3 which is seen during The Waluigi Arc. It lasted until A Day In The Life Of Everyone where his therapy show is cancelled, and later started his own production company which is later destroyed, forcing him to go back to his dark ways. He is the main antagonist of The YouTube Arc, having seized Susan Wojcicki's YouTube Remote and used its power to erase SMG4 from existence and take his place as a YouTube juggernaut.
He lived in a colossal fortress located in an unknown realm, and his best friend isNintendofan996 (Nintendofan997's doppelganger). He also earned a psychiatric degree before the events of SMG4 VS SMG3.
After many challenges and a rap battle, SMG3 is defeated and sent into the Internet Graveyard for his abuse of the YouTube Remote. He made one last attempt in making his career again, but is then attacked by Ugandan Knuckles off-screen, finally ending his long rivalry between SMG4 and the latter's gang once and for all.

It is the second adult animated series to be produced in Australia, the first being John Callahan's Quads!, and the first completely produced in its home country. The series is a parody of the Nintendo franchise Super Mario Bros (though it also features some original characters). where Mario, rather than being a hero, is usually kind of an idiot (however despite this, he did do some heroic things in the older episodes and still does it today). It had its first episode on May 7th 2011 with the first episode, the cake is a lie.
