For the unititiated, “Mary Sue” is a fandom term for original female characters that pop up in fan fiction and who are too ridiculously perfect to be believable. A Mary Sue is often incredibly beautiful and talented, with an incredible singing voice, and back when I started out in online fandom (circa 2005), she often seduced Legolas or the Phantom of the Opera. Mary Sues are reviled in fandom because they are signs of bad writing. However, I have recently realized that this hatred for the Mary Sue character type is sexist, especially since I’ve seen the term applied to two mainstream aspirational heroines: Rey and Captain Marvel.
