Do you think if Hashirama and Tobirama fought together, they could defeat the original Akatsuki from the start of part2?
Naruto didn't defeat the entire akatsuki all at a time.....Hmm.. If Naruto can, why not? They are 10 times stronger than Naruto. They could find some "competition" on Pain, but I don't think anyone of the rest could harm them at all.
Yes, I edited my post, my bad.Naruto didn't defeat the entire akatsuki all at a time.....
If you mean all at the same time, then No.
