Luke Lerdwichagul, also known as Real Life SMG4 (born May 24, 1999), is an Asian-Australian Super Mario 64 movie maker and the founder of the SMG4 channel as a whole. 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 also the voice of Shroomy, and the founder of Glitch Productions. He is also Kevin Lerdwichagul's younger brother.
At the end of the blooper Da Glitch, after the virus is destroyed, Toad is warped to SMG4's room in the real world. His identity as of then, was, unclear – SMG4 teased the community about this with the Facebook message "It probably could be me"; although it was finally revealed to be him in Smg4 vs ALS Ice bucket challenge.
In SMG4's deleted prank video, he was ostensibly revealed to have the first name Ryan; however, in Mario in real life!? (200 vid special), he is referred to as Luke, confirming that his real name is really Luke Lerdwichagul, as PathboyJosh found earlier.
In Mario in real life!? (200 vid special), the real-life SMG4 made his first main role in his blooper series. The special involves Mario and several other major characters getting warped to his house, making it necessary for him to get them back to their world before anyone finds out.
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 (Da Glitch) 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 "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.
In Yoshrooms., a Mii looking similar to SMG4's real-life self makes a cameo appearance at the end after Weegee has taken over the Castle and some of its residents.
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.
In a recent video in Hobo Bros called "Reacting To The "Important Videos" Playlist", Kevin stated that Luke is actually color blind.
This could have been a joke. However, when they watched a video called "color red", where a person searches color red on google, and a blue picture appears, it seems that Luke couldn't understand the joke, implying that he is, indeed, color blind.
What contradicts this, however, is that in the video where they made their tier list ranking Mario's designs, Luke mentioned that the colors of Mario/Jumpman's shirt and overalls back during the 1981 release of Donkey Kong were inverted, consisting of a blue shirt and red overalls.
He mains Jigglypuff, Peach, Little Mac, and King Dedede in Super Smash Bros.
