List of derived characters in BZPB

Because the Original Universe (and many other universes in BZPB) is an amalgamation of hundreds of different fictional universes, many characters in BZPB originate from other works of fiction. Some of these characters are copyrighted, but others were created for use in other forms of fanmade fiction. This is a complete list of all those derived characters in BZPB.
