@ohgodwhy: Um bro there is a limit to Naruto's Chakra so he probably couldn't level that entire with bijuu bombs let alone in 10minutes. Also Aokiji and Akainu are both very much capable of destroying an island and life wiping it in seconds. Their fight lasted that long because they are opposing elements. I mean if they wanted aokiji could have just frozen everything and akainu could have just melted the island. But that is besides the point.
Luffy is currently very capable of holding a candle to aokiji and akainu. The only thing stopping him from fighting was their intangibility and mastery of haki. Luffy has now mastered haki and can hit them and precog their attacks to dodge them. Rayleigh even said he already taught luffy all he knew and luffy surpassed his training and trained by himself after a year. Rayleigh was capable of fighting and hitting a light based being. I am 100% sure luffy can now as well.
I won't argue about the bijuu bomb because neither of us have seen the full extent of it in naruto's possession yet.
Also Tsuna has far surpassed naruto,ichigo and luffy so his place in the fight isn't even debatable. Also Tsuna probably will have a dying will bullet handy because he has barely if ever fought without reborn by his side ready to lend a hand. Reborn could shoot tsuna and leave without a problem because none of these fighters could hold a candle to him and if its morals off tsuna will make sure that happens. Ichigo can go final getsuga if he wants that isn't even questionable. He knows how, his morals are off and he has the ability to do so.He can also go full hollow and just cero luffy and naruto without question.
