Beret guy, as seen in 1117: My Sky
|First appearance||167: Nihilism|
Beret Guy is an optimist, and sometimes a naive one (although he is rarely a victim in the strip). He enjoys philosophizing, often taking the role of the existentialist. He has a very surreal side to him, often thinking about or being involved in bizarre situations. He also is shown to take things far too literally, sometimes making things surreal.
He has been quite fascinated with bakeries as in 434: xkcd Goes to the Airport and 442: xkcd Loves the Discovery Channel, in particular with scones (see 452: Mission as well as the title text of 677: Asshole and 1030: Keyed.)
Beret Guy had a steady job as a bartender, in three comics 328: Eggs, 474: Turn-On, and 712: Single Ladies. However, in later comics, he apparently quit his job to become a "business professional", according to 1032: Networking. See all comics about Beret Guy's Business. He apparently, makes a load of money off of doing this, but has no reasons other than the fact that he is "a business grown-up who makes business profits". He appears again, now with his own "real building he found" in 1293: Job Interview. In 1493: Meeting, his business returns again, this time with a name (CompanyName.website) and an explanation, albeit an unusual one, for how it makes money ("Money keeps appearing, but we have no idea how or why."). At this time, it is still massively successful, somehow.
Beret Guy also seems to be a miracle maker - see a list of the strange powers of Beret Guy. In 1099: Tuesdays, he grows "endless wings" and in the aforementioned 1293: Job Interview, he seems to be pouring soup from an electrical socket, as well as in 1486: Vacuum, where he misinterprets quantum physics and manages to get unlimited power from a vacuum cleaner. In 1490: Atoms, he appears to have a supernatural ability to see individual atoms (or at least the atomic make-up of items) and his mother seems to have had an unexplained amount of plutonium in her body. However, Beret Guy seems to have no doubt that these events are perfectly normal; in fact, he just seems to accept them as they are without question.
In the What if? Glass Half Empty, he seems to be quite oblivious to pain, especially about foreign objects sticking into his head. This may explain why we never see him without his beret as it may have been stapled to his head - see title text of 291: Dignified.
To sum up, Beret Guy is a very naive man with the strange superpower of having the world around him acting according to his naive vision.
