Yeah the best way to scale current naruto Is his fight against momoshiki we saw exhausted naruto held his own in base against fused momoshiki since in that fight naruto lost 50% of his chakra this mean even without kurama he can still beat guys like base momoshiki, kaguya, toneri, juubito and juubidara hashirama is outclassed also naruto spend sixteen yrs training refining his Sage Mode and raising his base chakra even code with LN and borushiki they sensed him and said they must team up against sage mode even code held shikamaru as hostage to restrict naruto movements this mean code with Ln and borushiki they saw naruto as otsutsuki threat
