This may be just a fun thread for mass quick replys..........
.However I do see this happeing in the future of the manga(FINAL BATTLE VS MADARA)......Naruto Ninetails vs all the other bijuu in a Nuclear world destroying battle!
Kyūbi Naruto seems undefined here, and in the case that it means Naruto fully committed to the use of the Kyūbi's powers (all nine tails), then it is an entity we know nothing of. Only one of the other eight bijū can really be discussed, as we have only properly seen Shukaku in combat. Some of the eight we have never heard of, seen, nor have any idea of the powers of.
4. Post threads only if there is a discussion to be had. Threads posted can fail to leave opportunity for discussion if a) they are too speculative, with little to nothing known of one or more of the shinobi involved, or b) the outcome is self-evident without explanation. Threads where the outcome is clear without any discussion should also not be posted (e.g. Hinata against Jiraiya).
