You mean Xena? From what I gather, Xena wasn't a canonically confirmed lesbian/bisexual (she was awesome regardless). There are, however, examples of canonically gay/bisexual characters in the media that I think are/were more or less well-handled (as in not just an example of tokenism). Willow in BtVS, and Billy and Teddy in the comic-book Young Avengers come to mind. (Because I'm a fan of both - the tv show and the comic.)

I still need to see more latin-americans that don't follow the stereotype, though. And this is coming off awfully like a wave of the victimhood card and I'm sorry but, gah, it can be grating some times.
