Naruto has wind saske has fire so Naruto needs another to have the upper hand any thoughts on what it will be I think earth maybe water just so
he would have new jutsu against saske what do you think.
Sasuke has two chakra natures; Fire and Lightning. Naruto doesn't need another chakra nature to have the upper hand or tie with Sasuke. If Naruto does end up having another chakra nature, it should be Water.
Yes he need water to counter sasukes fire release but since he's mastered control over kurama he doesn't need to cause kuramas chakra element is fire it won't work on naruto
