I actually had a good discussion about this in a chat recently. And, while not an entirely blank slate workout gender or form, I still think this one character fits the general idea of a blank slate.
That character would be Chel. Yes, that one, from the nearly universally adored Portal series. Just think about it, she has no clear back story, no voice, and no motive other than progress (and by extension, staying alive).
While she can be attributed characteristics of being courageous and defiant, she really only becomes these things through player action. The player's motives are her motives, if only because they are about moving forward.
She has no thoughts other than any the player may have for her. She is truly just a model to project onto. But that's not such a bad thing.
