510: Foreshadowing of Naruto's powers and KG
We have already learned that there is a yin and yang nature of chakra.
Madara stated that the Yang part is used to "breathe life".
We have actually seen this when Yamatos Mokuton reacted to the Kyuubi's Yang chakra.
As Yin and Yang now seem to play an essential role to the powers of the SOT6P.
Since Naruto is of the Uzumaki clan which is one of the six paths his new abilities are likely to be related to the Yang nature of Chakra. The longlivety of the Uzumaki clan is another clue to this.
And remember: If madara isnt lying the Rinnegan is not an Uzumaki KG, but was given to Nagato by Madara.
So the Uzumaki KG is probably the manipulation of the "life-giving" nature of Yang-Chakra. This is the Uzumaki Path of the Six Paths.
Naruto's "that jutsu" might have something to do with this.
But to be honest: I have no idea how this powers would actually look like
P.S.: The wood element of the Senju could point to their role as one of the Paths: Yin Chakra Manipulation ("The power to create from imagination") But there's not enough evidence. Just wanted to put it out there
