Oda's not the type to make things cliche. Even if said thing is SUPPOSED to be cliche, he can make it epic. Example being the Alabasta goodbye. Everyone could have expected some cliche, heartfelt goodbye with hugs and everything. But instead, Oda made that moment one of the most epic One Piece moments ever. So I'm expecting something epic with Shanks and Luffy's meeting.
Well, for me the best shichibukai was Crocodile, of course, but now that he's not a shichibukai, I think that the best is Mihawk. But I want to know more about Jimbei, and I like Boa, too. It's a pity that Jimbei is not a shichibukai any more, but I'm glad that he's helping Luffy. Oh, wait, maybe I'm telling you too much... You read the last chapters?
