But Tobirama stated they were almost at full power.
There is plenty of proof. Hashirama has NO feats even half as good as SPSM Naruto's. And Madara didn't curbstomp Naruto at all. This was what Naruto did to Madara.
He literally thwaked him and cut him in half. And this Madara is far stronger than Hashirama. And we do know Hashirama's true strength. His strongest attack could rip the PS, but not completely destroy it, and the PS is far less durable then ten tails Madara, so Hashirama has way less AP than Naruto even in Base Six Paths.
Ok and that's impressive...against non six paths level characters. Which Naruto is.
Sage Mode is far more than a 10x amp, compared to the 2x amp from another half of Kurama.
No...six paths abilities? Excuse me? What about Naruto saving Guy and Obito or restoring Kakashi's eye? Or using TSO. Or Sasuke using chibaku tensei and six paths chidori and the deva path? Amentojikara? The list goes on and on. Of course they can use six paths abilities, and they would each fodderize Juubito before Juubito even sees them.
