@youngirishboyo:
i have a theory on what will happen, and its good one…
Possibility 1
that Luffy saves Ace, and with the help of Ace, Boa, and maybe the White Beard Pirates, they will go collect the rest of the Straw Hat crew. and since Oda wasn't the guy who wrote the never ending anime Dragon Ball Z he'll have to keep it short, and have Kuma give Luffy the location of his crew.
Possibility 2.
Luffy saves Ace, they say their goodbyes and then Luffy and Crocodile are transported to Shabondy arpeggio where they wait for Kuma to send the SH crew to Shabondy... then they will collect their ship from Rayleigh and go on to fishman island.
what will happen
ok now for what will happen, since Luffy is the only Pirate to destroy Enies Lobby, break into and escape Impel Down, and take the Marine HQ on and rescue a person who will b put to death. His bounty will at least double. and as a side note no matter what he will get a new nakama but its TBD.
Possibility 1 : Kuna is not involved, Ace and the Whitebeard Pirates can't go on search for few friends of Luffy… they world as just become a mess.. they need to reclaim their place. Oda has around 450 more chapters to go... he can take his time
Possibility 2 : Luffy and Crocodile transported there.. sure. But Kuma sending the crew mates back ? Not happening again.
What will happen : He already got his bounty for Enis Lobby... what bounty increase he could get is for punching the World Noble.. being first to break INTO impel down and mostly destroy it. Showing his Haki powers in front of the Marines. We will maybe see 400-300 bounty but before Oda would show us higher bounties. And Luffy would go straight to Rayleigh to see if any of his friends are back.
They will not get just get teleported back... they are separated to also show that each of them are now strong and could get him/herself through first part of the Grand Line. They each do it on their own way...
