Naruto team with no diff. Itachi with Kyubi cloak? My goodness... Help us all...
But let's not forget about a rampaging Hachibi encased in perfect Susano'o.
Naruto's team most likely wins. Itachi is a non factor here.
Edit : Sasuke can armor Bee with PS ? Then I don't see how Naruto's team wins.
Itachi is a non factor with Kyuubi cloak?
Ps covered Hachibi nukes them.
Itachi can just use Izanami on Bee to make him repent for tormenting Karui and Omoi with his awful rapping.
Itachi is a non factor with Kyuubi cloak?
Bee gets taken out by Amaterasu, unless Sasuke can stop Itachi's flames.
BM Naruto ends both of them withPs covered Hachibi nukes them.
