Good suggestions, thanks. I am going to apply the following arbitrary rules:
1. No Atomic Blonde before its release.
4. No Antipoe because I cannot remember which one she was (Wright I would assume, but still), and also because one Amazon per movie is quite enough, poll-wise.
2. No Ahmanet because she is not a protagonist. Also, I've not seen the movie.
3. No Alice, because, well, I don't like the series, and also, we've seen her a bunch already.
4. No Split girl because she does not fit the bill.
Considering your list I am surprised you did not include the emo from Underworld.
Honestly, at least some of these are better characters than Furiosa. They certainly have more complete arcs and more developed personalities.
