Suethor

A Suethor is, as the name suggests, a person who writes a story in which the protagonist is a Mary Sue. Often Suethors don't realize that their beloved protagonist is a 'Sue, to the point that a fairly good sign that a story is a Suefic is an Author's Note insisting that their story isn't one. Many don't know what a 'Sue is, or only know about one or two characteristics. There are, however, some Suethors who just don't care.

Many writers start out as Suethors, but most grow out of it, often around their late teens. This can even be noticed in published fiction; Amelia Atwater-Rhodes, Flavia Bujor, J. Fenimore Cooper, and Christopher Paolini all have protagonists who are Mary Sues. Eragon and Natty Bumppo are two of the most blatant Mary Sues in existence, even counting the many 'Sues in fanfiction.
