You guys are getting ridiculous with this. It is not yet time for Nami to be able to contend with someone like Ulti in a one on one fight. I don't care about her Doublefinger and Kalifa fight. Those two, while stronger than Nami at the time, were not leagues above her level like Ulti is. Nami is at the bottom of the barrel when it comes to physical stats, while Ulti, being an Ancient Zoan is categorized in the third strongest tier in the series. Her physical capabilities are miles beyond anything Nami can currently achieve. The Tobbi Roppo/Veterans are characters who are strong enough to be able to give Yonko commanders a decent fight, and you want Nami to get some glorious moment where she surpasses her limits and takes Ulti down in a 1 v 1? The girl doesn't even have one form of Haki yet. Nami's time to shine and beat a Vet level character on her own will come, but right now damn sure isn't that time.
