I might be mistaken but was narutos eyes different kind of like a cross when he was in sage mode and the red fox chakra in him .... just wondering .. if you dont kno juss take a look at the manga or the one before it ... one of them .
I agree completely....once he is able to mix those two, he will be the most powerful and easily the fastest (without space/time transportation) ninja in the world. When in that state, i'm not even sure that Might guy with all 8 gates open would be able to beat him....thats a deadly combo though .. think about it ... sage mode + red fox chakra mode.....thats crazy
Unsure, but that brings me to my theory for the future....I think that naruto will go to train with Killer bee on how to tame his beast, as he is the only living person in that world that knows how.....yeah exactly... and i wonder how long it took the 8 tails holder to master him...
I think kyubi was trying to get over, trying to take the advantage that Naruto was angry, the poor fox is bored of sitting inside Naruto.
And that even if Naruto trains with killerbee, it will not be to release the fox. Minato has made it clear that the 8 tails is the most of a released fox the seal allows.
