I'll admit, I haven't watched the 3rd season so I'm not sure whether canon has jossed it, but: Taystee from Orange is The New Black.
I though of it initially as someone else's headcanon as her as ace and I was like, "Nooo... really?" But it makes sense (at least in context of S1-S2). She hasn't spoke of previous romantic/sexual relationships (though this wouldn't be invalidating either), enjoys close platonic relationships. She said that she wasn't "like that," after her friend Poussey kissed her. Most people interpreted as "being straight, not interested in women," but I thought it was interesting to think that it meant "not interested in romance/sex in general." I don't know, I could list a bunch of stereotypes she fills, but I just feel like she could be aroace because she's never indicated otherwise. I also really like it because she's not a "stereotypical" aroace (ie: quiet, emotionally closed off, serious, loner). She's brash, loud, and really, really funny. Her being my favorite character also doesn't hurt.
