Outside of his own series, he, along with Chris, became prominent but recurring characters during the ninth season of SMG4.
Swagmaster is arrogant, unintelligent, cocky, and tends to be uncaring and mean towards others. He prefers to screw around instead of doing what he is supposed to be doing, which is one of the main reasons why he and Chris get into so much trouble most of the time as guards working at the spaghetti factory. On some rare occasions where he is focused on the task at hand, he is very resourceful and can get out of many sticky situations with his quick thinking.
On occasion, Swagmaster appears to enjoy singing while he is goofing around; however, he is apparently tone-deaf, as the characters around him start to panic and cringe in pain whenever he sings, making their ears bleed.
He also seems to have a dislike for anime as shown in SMG4: Mario's Prison Escape, stating that the van that Saiko Bichitaru is in needs to be immediately destroyed since it had "anime on board". In SMG4: The Inkling Disappearances though there's a scene which shows him and two anime scenes, where he says that "he has seen too much" and explains that because of that, he is probably going to have difficulties in coming back to "civilian life", probably meaning that either he actually grew to like anime (though it's most likely a love-hate feeling) ever since it was banned, or has been traumatized by it, given that when he sees Saiko again, he claims he's having Vietnam War flashbacks again.
