Of course, one of the strongest ninja is the protagonist, Naruto.
Naruto is the strongest shinobi in the entire story and like Sasuke, a user of the Six Paths powers.
He has the chakra of all the Tailed Beasts at his disposal along with the ability to use the Six Paths Sage Mode.
His rivalry with Sasuke is the stuff of legends, and it eclipses in what is easily one of the greatest battles in the history of shonen.
He is the Leaf's 7th Hokage, and he is arguably the strongest Hokage in history.
Naruto managed to become a perfect Jinchūriki when he and the Nine-Tails became partners, and the Tailed Beast's vast and powerful chakra greatly enhanced Naruto's strength and abilities.
