I was wondering how long it would be before I'd come across a picture of a gender-reversed Buffy the Vampire Slayer cast on deviantart. A certain section of fandom loves to play around with cult media archetypes, amalgamating them, reimagining them as part of different genres (I've also seen pieces that show the Buffy cast as bona fide spandex-clad superheroes) and yes, gender-reversing them. Just go and search for "gender reversed Teen Titans" and you'll see that I'm not kidding. Again, all I'm saying is, I'm surprised it took me this long to find an image like this.
Incidentally, I'd be horrified if I found that someone had written gender-reversed Buffy fanfiction. The reason being that, hopefully, any amount of thought on the part of the author would make them realise that a gender-reversed version of the BtVS plot would be exactly the same, unless of course one happened to hold some bizarrely sexist beliefs about the differences between the sexes. 'Alexandra' would still be a clumsy, horny teen; 'Will' would still be a shy geek with an interest in the mystical... And yet, a part of me just knows that some idiot somewhere has written this thing, and that it features tonnes of purple prose about how the newly-female characters are just "so much more sensitive" and other puke-worthy rubbish.
So yeah, this works as a visual experiment, but please tell me there isn't crazy, sexist fanfiction about all this stuff.
