I actually posted a reply in another thread about this topic which seems to me doesnt have much attention at all. I was just thinking what would happen if the 8-Tail Jinchuriki were to fight Naruto or something along the lines of the uncaptured ones coming together to form an alliance or something against Akutski.
I for one would love to see a fight between two jinchuriki and watch them go all out berserk on each other.
