Nico Robin is pretty tough and her attacks shouldn’t be underestimated. Using her hands technique she can fly and trap her opponents. Of course I don’t think it would work thanks to Sakura’s amazing speed and power. This is one fight that Nico Robin just can’t win. Sakura rises up the ranks with this win. Sakura wins.
Nico Robin has hand powers, but they won’t work on Zoro. Zoro’s swords would just slash through and defeat her once and for all. This isn’t too sad because no one can defeat Zoro. He’s undefeated and that’s the cool part. Zoro wins.
