MS Paint Adventures, and Problem Sleuth in particular, contains a large cast of plucky and likeable characters, and also some characters who aren't so plucky or likable. Actually I'd say the pluckiness and likeability of the cast runs the gamut. Jailbreak has some notable characters who show up in many more adventures, Bard Quest has the ridiculous Bard, and Homestuck is quickly piling up a huge gaggle of characters; more than you can shake a radioactive dog at.
Oftentimes a character in Problem Sleuth will have a large number of alter egos, alternate forms, imaginary counterparts and/or time travel duplicates. This is just a natural part of the Problem Sleuth universe and it all makes perfect sense, we promise.
