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 the CEO 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.
Kevin is the writer of the more recent SMG4 episodes, starting in 2016-17.
He is good at Martial arts, unlike his brother Luke (possibly).
