Nustar, or more accurately the Six Paths Senjutsu, is one of the most formidable abilities in 'Naruto.' It's granted by Hagoromo Ōtsutsuki, the Sage of Six Paths, and essentially elevates the user to near-godlike status. Naruto Uzumaki wields this power during the Fourth Great Ninja War, and it completely changes the tide of battle. With it, he gains truth-seeking orbs, flight, enhanced sensory perception, and the ability to use all nature transformations. The power also lets him heal others and even resurrect the dead to some extent. It's not just about raw strength—it's a holistic upgrade that makes him nearly invincible.
What really stands out is how Nustar contrasts with Naruto's earlier abilities. Before, he relied heavily on the Nine-Tails' chakra and shadow clones, but with Six Paths Senjutsu, he's operating on a whole new level. He can go toe-to-toe with Madara Uchiha, who's wielding the Ten-Tails' power, and later Kaguya Ōtsutsuki, the progenitor of chakra. It's the kind of power that feels almost unfair, but it's narratively justified because of the stakes. Without it, the heroes would've stood no chance. Even so, it's not infinite—Naruto eventually loses some of these abilities after the war, which keeps the power scaling from getting completely absurd.
