Post-time skip Strawhats VS Naruto
Strawhats are bloodlusted
Naruto is IC and is in his current form in manga
Luffy's got better durability (despite the bijuu bomb trumping it) and better speed, He could just blitz and do a Thor Elephant gun, which if Chinjao was as strong as his youngerself, matched a near island level attack, possibly city depending on how much time has changed his strength.
There is seemingly no 'perfect' way to truly say goodbye. So I gathered a bunch of them!
