Their names are Cueball, Megan, and White Hat?
It is my understanding that XKCD’s “characters” are somewhere between an actual character and an archetype. It isn’t clear…and kind of doesn’t matter, if Black Hat is the same guy in every comic or if he’s a different devious schemer in each. Randall hasn’t bothered to name any of them so the community has given them unofficial nicknames.
I remember reading about their names in explainxkcd. I think the only one never named in the comics is Cueball.
For a while, there was a blog, but I don’t think it named any character.
