She does, she is one of if not the most powerful character in terms of innate physical strength and toughness, she has one of the most powerful and versatile devil fruits in all the manga and has all kinds of haki.
Unfortunately she is is nearly always handicapped and dragged down by Oda's writing, with him having nerfed her and put her through incredibly silly and stupid situations, and who has never allowed her to use her true potential so far. And I seriously think that Oda isn't capable of handling female characters right anyway.
