A Slightly different Ranma

[Crescent Pulsar]

Not really... I mean, I know there are some fics out there that address Ranma's decision to not go along with the "manliness doctrine", at some point, but I don't recall any of them favoring his female form, or his sexuality being that of a lesbian. Lesbian 1/2 may very well be the only story that has all of the elements that you're looking for, since some of the ideas used are either either fringe interests (Ranma being a lesbian, and preferring his female form), or farther out than that (hating men). Which is likely, since the fic itself was meant to be a parody, rather than a story that addressed the plot elements seriously, as far as I recall.

Battlekrome! Dude! That's the story that's been teasing my brain since Spokie made this topic! Man... At first I had Lesbian 1/2 and Blonde 1/2 a bit confused, but then I was sure that a Ranma-chan with blonde hair was some other story. I just couldn't think of the name (even though it's so obvious, now), since I was still more focused on what Spokie was looking for. Which is to say that I didn't think the story would apply, but years away from reading fan-fiction obviously hasn't done my memory any good... I think I'll actually read this story again, and find out. Shouldn't hurt. XD;;

(And thus you have all bore witness to a rare display of enthusiasm, on my part. Savor it. It doesn't happen often. ;p)
