Sasuke- Perfect Susanoo'
Naruto: Other half of Kurama's chakra/ Rinnegan.
And like Hixa Kuogame said, I hope they don't surpass them cause both Madara and Hashirama are already on a whole different level then everyone else. And putting Naruto and Sasuke above them would basically be making them out to be God like. Which in my opinion would be somewhat stupid to the story and just get it outa hand. But that's not my choice to make. That is Kishi's. But don't get me wrong I like the new powerups that they both have now but I think that's as far as it should go.
I understand, but its clear that both Sasuke and Naruto are even more chosen than Madara and Hashirama.
Madara - A literal direct descendant of the Elder Son. The strongest the Uchiha have had.
Hashirama - A literal direct descendant of the Younger Son. The strongest Senju have had.
Wouldn't it be completely redundant to use the whole "Mirroring both sons" case/parallel again? It was done to the tee with Madara and Hashirama.
What already smashes that away is Naruto not being of Senju descent. He's an Uzumaki. Uzumaki's have displayed better vitality and larger chakra reserves than Senju's in the show (Naruto currently has more chakra than Hashirama) which puts them on a whole other level of "Gaining the Life Force and Yang Chakra" from the Sage like the Senju.
It's more like this: Sasuke vs Naruto is a clash between the actual ideals of the Elder Son (Power but in Sasuke's case, no peace involved) and the Sage himself (Naruto's wanting for peace). Sasuke must bear the burden of the entire Uchiha clan whereas Naruto has been called "The one" by the Bijuu's, with obvious reference to the actual Sage.
Thanks for your input again!
