Tekkai=can't move and can be penetrated by sufficient force. Sorry, but I think that against someone like Zoro or Luffy capable of shattering Tekkai, she would lose.

But you have a good point saying that she has an overpowered DF. Hell, she came pretty close to taking out Moriah on Thriller Bark, closer than any of the other Straw Hats. Most fighters simply are no match for her, which is why she rarely gets 1v1 fights.
