C. Naruto has a lot of Chakra and his chakra is dense enough to burn.
D. Senju are capable of using extrodinary powers
Therefore with D. - Naruto can do a shitton of Shadow Clones, Hashirama can create a forest, Tobirama can make water out of nothing and Tsuande can heal an entire village.
E. IT WAS HINTED
UCHIHA VS SENJU
SASUKE VS NARUTO
That's all folks.
There are plenty of scenarios in which Kushina could become a Jink without being related to a Hokage. Plus, again, Sarutobi has a decent chance of not being Senju.
Someone very powerful: THE SHINIGAMI. YEAH. PRETTY FUCKIN POWERFUL. BECAUSE THAT'S HOW TEH RDS WORKS.
Nagato also had a fuckload of chakra. Nagato is definitely not Senju.
For Naruto that is purely based on having an absolute shit-ton of chakra. For the other two, it's both "a lot of chakra" and "a lot of skill." There's a difference.
It was said that Naruto v Sasuke was a battle of the Senju IDEOLOGY vs the Uchiha IDEOLOGY. Naruto personifies the "Will of Fire", but being a perfect example of that philosophy which was made by the Senju does not automatically make him Senju.
