Ryokugyu isn’t going within a 100 mile radius of Akagami after the Wano incident. There’s no need to have a GV parallel since that was a mind controlled version of Xebec anyways
literally told shanks he was down to fight him later on
but like i said, mihawk is more likely
what mihawk needs more than ever is to prove himself against another black blade forger, aramaki is the perfect victim
2 takes worse than Killingham vs Usopp, impressive
the koby one is just common sense
garp and roger jumped rocks
koby (garp parallel) and luffy (roger parallel) jump teach (rocks parallel)
the aramaki one is a bit more up in arms, but honestly, what else would happen to him?
unlike issho he's clearly a villainous character who likely won't be redeemed, and the only top tiers i could reasonably see him fighting are mihawk, shanks, and teach, but teach likely won't care about him that much
