I've never read JAG fanfic. Never cared for the show enough to be interested. I'd go back and forth watching it and quit before the last couple seasons.

I don't know anything about Gundam Wing other than hearing of the title.

I used to read X-Files fanfic in its early years and not much at that.

Presently I can think of M7, sg-1 and Atlantis (although there've only been hints in some of Atlantis fanfic I've seen). Actually it's not in het fic I find this occurrs. It seems to happen in slash fic.

Usually the female character turns into this uber bitch or desparate to get the guy.
