Kevin Lerdwichagul (born 21 June 1994) is SMG4's true older brother, who first appeared in Mario in real life!? (200 vid special). According to him, SMG4 has never completed a Zelda game. Kevin is a "true Zelda fan" who has played all the games.
As mentioned in one of the mail videos, SMG4 and Kevin created a company called Glitch Productions. The company is responsible for the management of SMG4 and Hobo Bros. Currently, he is one of the CEOs of the company.
In an episode of the Hobo Bros in one of the NSMBW gameplays, "THE BIRTH OF FISHY BOOPKINS AND THE DEATH OF BOWSER JUNIOR", Kevin confirmed that he doesn't like Fishy Boopkins (yet doesn’t loathe him).
Kevin loves Anime.
He used to have a DeviantArt account called "oceanweapon" where he posted comics, drawings and animations related to anime and video games, particularly Zelda and Fire Emblem.
