One of the things that I have noticed upon becoming an admin of these kinds of wikias, is that people do not understand the definition of the word 'villain'.
Googling the definition states that a villain is "(in a film, novel, or play) a character whose evil actions or motives are important to the plot".
The first problem with this, is that PBG reviews, are not some kind of film or play, it is a review show, not a action film, so there are no good guys or bad guys.
In the case of the Smiley Man (the closest that PBG has ever had to a villain), he is clearly demonstrated as an evil character, but he never does anything that makes him a villain. Yes, he did kill his family, which makes him evil, but he never does anything against PBG apart from giving him sucky presents. That makes him a jerk to PBG at best.
Finally, note that villain does not mean hate. A villain has to actually DO something to make him a villain. Something that PBG does not like does not make it a villain. For example, I don't like the taste of licorice. Does that make licorice a villain? No, so therefore, something that PBG hates is just something that he hates.
The best chance of a villain appearing in PBG's videos, might be in Hardcore, as that is more of a "film" or "action show" rather than a review. However, as they are still playing a game, we use enemies or bosses instead.
On the flip side, PBG himself is not a protagonist, as he is just reviewing games, with some skits or jokes thrown in. These jokes are rarely "canon" and should not be taken seriously.
So, unless PBG changes his show to be more like ScrewAttack's Metal Gear Ben, which does have villains, The PeanutButterGamer Show has never and will never have villains.
Hope this helps when creating pages for characters that appear in skits, as it can be a difficult to realize that we are talking about a factual show, rather than fiction.
