Luke Lerdwichagul, (also known as Real Life SMG4, Asian SMG4, or just SMG4) (born May 24, 1999), is an Asian-Australian YouTuber, machinimist, director, animator, editor, actor, voice actor, comedian, and the founder of the SMG4 channel as a whole and the co-founder of Glitch Productions. He is represented in videos as SuperMarioGlitchy4, a blue-and-white color-swapped Mario and one of the main protagonists of the bloopers. He is the director, animator, editor and former writer (now handled by Kevin) for Super Mario 64 Bloopers/SMG4 and the founder of Glitch Productions. He is Kevin Lerdwichagul's younger brother.
In SMG4: Stupid Paper Mario, because he as SMG4 managed to spend his money carelessly on a crane game he kept failing at, the SMG4 world deteriorated until it became real life with him at the end using a fake computer. Fortunately, Mario (as a plush) managed to give him real money, causing the world to be returned back to normal.
In recent videos, he has been advertising several company sponsors/his limited merchandises on his shop to the viewers before the start of each video alongside his brother Kevin.
On the (now deleted) video of some of SMG4's friends playing a prank on him, the real SMG4 looks sorta like this guy, though his face is never seen.
In the "SUPAH SMG4 PACK" on Google+, a picture states that he looks Chinese, in the many pictures on this page and in the video, he may look Chinese to some.
SMG4 lives in Australia at the Southern Hemisphere, and the blooper where the guy appeared (Super Mario 64 Bloopers: ÐД gℓî†¢ђ) is made near June, since Australia is in the Southern Hemisphere where June-August is Winter and December-February is Summer, the time in Australia near June becomes cold due to winter coming, the guy is wearing jeans probably due to the cold.
In the end of "Super Mario 64 Bloopers: ÐД gℓî†¢ђ", the guy's computer shows Sony Vegas that is open along with Starman3 with golden glowing text in the preview box. This may have been SMG4 in the process of making the blooper before it was uploaded.

It's possible that Luke may be of Indonesian descent. In the video Super Caveman Bros., the Barney video has Indonesian subtitles and the footage probably comes from a DVD Luke bought from Indonesia. However, that is incorrect to him according to a Hobo Bros episode.
In a Hobo Bros video called "Sans in smash memes that will give you a bad time", Kevin stated that Luke is actually color blind. The pair proceeded to take a color blindness test which confirmed that Luke is red-green colorblind. Which is also confirmed in the video Reacting to the FIRST ever SMG4 episode.
He mains Jigglypuff, Peach, Little Mac, and King Dedede in Super Smash Bros.
He might be a Studio Ghibli fan considering the announcement video "A genuine message to our fans" has a shirt that resembles Studio Ghibli's Japanese Blu-Ray covers as well as Studio Ghibli music in the background.
