Naruto stomp all over them "legendary" faces son, sorry
Hashirama is useless if Kurama is inside his host, just like Madara's stupid eye control is useless
How can you suppress a Jinchuuriki's chakra? its one thing to suppress it when they aren't in control but you are talking about a whole new technique, if it was possible don't you think Tobi would of suppressed Bee by now? considering Bee is the "perfect" jinchuuriki?
If you really think the "legendary" ninjas are going to be above Naruto in a series called "Naruto" you are 12..go write a fan fiction
