oooooooohhhhhhhh it might be that guy in the coffin that kabuto had......nope nvm that was dumb!!! im still wondering weho it is though???Senju Hashirama(1st Hokage) was one of the six paths.
Uzumaki Nagato was 3rd of the Six paths.
Uchiha Madara was the 2nd of the six paths, now 1st and 2nd and prolly 3rd too when he has obtained Nagatos power too.
I am pretty sure Naruto and Sasuke are 4th and 5th.
So it remains, who is the 6th?
