fanon
n.— «Writers and readers maintain a strict distinction between “canon,” the original works as Rowling wrote them, and “fanon,” the embellished, alternative retelling by fans. (In canon, Draco Malfoy is evil; in fanon, Draco Malfoy can be any number of things, including a leather-pants-wearing hottie who’s after Hermione’s goods.)» —“Taking Liberties With Harry Potter” by Tracy Mayo Boston Globe (Mass.)
