I’ve been an advocate of a theory made by me, that this are the last bounties they’ll get. After they conquer laugh tale and win against the WG there won’t be an government to issue bounties on them anymore and other pirates won’t be able to do it either(like Doffy did). They will be the freest pirates in the sense that nobody is going after them or trying to beat them, as it is not possible to do it.
I could be wrong,but i think this will happen:
2-Loadstar(last island) and Laught tale.vs BB happens here.PK Luffy gets abounty above 6bi.
3-Final Saga:WG vs Pirates,Revs and Enemy nations.
I think Im will be the final boss,not BB.
