I was hyped when Kurama's chakra leaked through his SM when faces Nagato & base 9tails SM was introduced. Naruto really look beast when he had Kurama' eye slits over his toad SM.
It had such massive weight to it when Haku was just wrecking both Naruto and Sasuke and in just twenty seconds the tables are completely turned when Sasuke is hurt...
I was more hyped when he was holding his own against pain sans kurama(up until he gets caught of course) most of narutos fights prior where kinda stumbling on a victory or completely won by kurama taking over
