I've been thinking about how Naruto will fight from now on in BM. And well, since I had too much time on my hands I decided to make an overlong post about it Especially I've been wondering about his replacement for KB afterall his goal is to be stronger than he was with SM. Not only is Naruto losing his entire bag of tricks, which is what allowed him to defeat most of his opponents, but he's also losing the FRS and the Oodama Rasengan. Even should he combine SM and BM one day I sincerely doubt he'll get the FRS, though the Oodama is a possibility. If you think about his fight with Pain it should be apparent how much the absence of bunshin and FRS is going to limit Naruto's tactical options. Yes, I know he's crazy fast in this new mode, but not that much faster than he was in SM and to Madara and Sasuke speed is nothing. Yes, he can use those chakra arms, but a) Sasuke has already seen them and won't be surprised by them and b) Sasuke can just incinerate them with his Amaterasu. besides they are rather clumsy. Even the new Rasengan, which will probably end up the same as the bijuu blast isn't that big an improvement. The move has been defended against so often it can't be expected to succeed now. It mostly fills the gap the FRS left behind. Right now I don't really see how he's much stronger by relying on BM instead of SM. Especially if you look at how he fought against the Kyuubi once his mother filled his vessel with love. If anything he's weaker since the loss of his trickery is worth more than gaining those chakra arms imo. I think this adjusting the ratio of plus and minus chakra thing he's learning right now will be used for much more than the Rasengan. Depending on what properties the two types of chakra possess, the manga seems to indicate the white chakra is soft and flexible, while the black one is hard and heavy, Naruto's future fighting style could be based upon combining the two lessons he learned in this training session. First to shape his chakra shroud as he desires and second to adjust the ratio of the two types of chakra he has in bijuu mode. The black chakra is what makes the new Rasengan so hard and heavy and due to it's weight it doesn't seem to move very well. Whenever Naruto has used it in larger quantities he has been standing either in place or while he fought Pain he had to materialise an additional pair of legs to move his otherwise immobile body. The black chakra is also what allowed a defense which not even Kusanagi could break through. The white chakra is soft and flexible as we've seen numerous times when Naruto used it to grab a tree or when he used it to propel the bijuu ball forwards at a high speed, but it offers little to no protection when the chakra isn't moving rapidly as we saw when Naruto sprained his ankle by crashing into the wall. Presumably it's also what burned so fiercely when Sasuke incinerated the Hachibi and why Sasuke could cut through the Hachibi so easily. We know Naruto won't ever master numerous jutsu and with Kagebunshin sealed he needs a completely different fighting style. So it has to be something simple and effective. Move with white chakra at high speeds and using that inhuman mobility, which allows counters even while the main body gets hit, and for a short moment use black chakra to amplify an attack, by let's say encasing a fist in black chakra before it hits, or to increase the defense against physical attacks as we've seen many times. Well what do you think?
