Without Kurama, Naruto is significantly weaker than he was with the Nine-Tails Fox's power. Kurama contributed immensely to Naruto's chakra reserves and stamina, enabling him to perform powerful techniques such as the giant Rasenshuriken, massive use of shadow clones, and enhanced endurance. Without Kurama, Naruto no longer has access to this vast chakra boost, which drastically limits his ability to spam powerful jutsu and maintain stamina in prolonged battles. However, Naruto remains very strong even without Kurama. He still possesses his own natural Uzumaki clan chakra reserves, Sage Mode, the ability to use advanced ninjutsu like Rasengan and its variants, and formidable combat skills. His base strength and chakra are likely above most regular ninja and comparable to high-tier Kage level without the Kurama boost. Moreover, Naruto retains some access to Six Paths chakra and his inherent raw talent and trained abilities, although he is distinctly weaker than his peak Kurama-powered self. In summary, Naruto without Kurama is:
- Significantly weaker in chakra capacity and stamina, losing many of his most powerful abilities.
- Still a formidable ninja, with strong Sage Mode, high-level jutsu, and solid physical skills.
- Likely to be at least Kage level, though much less powerful compared to his Kurama-enhanced form.
- Not as strong as top-tier opponents like Sasuke with his own strongest powers or Kurama-enhanced Naruto.
This assessment is based on both fan discussions and content from the Boruto series where Naruto is currently without Kurama, showing that although he remains very capable, he is a shadow of his former Kurama-enhanced self.
