Sasuke was going to destory the 9 bijuu and you're forgetting how Momoshiki and Toneri's kit works.This a joke?
Toneri is a shit compared to Sasuke.
Sasuke destroy a pathetic enemy that even a Bijuu mode Naruto can deal.
Plus a Filler character from a pathetic movie never will be compared to Sasuke.
With 9 Bijuu and PS Susanoo.
Momoshiki would have his ass wrecked.
The world would have ended, fam.
If not Toneri, then Momoshiki was definitely about to end things.
But it doesn't matter as Sasuke didn't even get to that point in the first place.
