Any ideas?

Well, sort of depends. If you're looking for a traditional view of fate, then someone who can't be affected by fortune can't really work in an RP because nothing is preordained without severe railroading. 

If you have a more ethereal view of fate, then you can go with an immortal outsider. A long lived sage who's sole ability is to not die + slow regeneration. Therefore, you'd be out of the fate of humans. Then you could play with lost memories because of all of the deaths, or be a living historic tour guide.

If you want to go pure bare bones, there's always the trait of an "against-the-odds" fighter. Bland, vanilla.

It's kind of rough because the concept of being stuck inside of fate has a lot more paths than stuck outside.
