Archetypes are ready built characters. They can be used as-is, or as a jumping off point for the imagination. They are built around some central concept, deriving either from the show, centering on a Quality or Skill, or being from some other source.
Included in each is the standard layout found in the Buffy RPG books - game stats, description, quote, and roleplaying notes. In addition I've included some design notes. These discuss what I based the character on or where the idea originated.
