@Fire Fist:
This is the same thing we had with Franky during the Enies Lobby Arc. Franky was in battles. Franky was in a battle colorspread with the Strawhats. Franky was the most prominent non-Strawhat fighter during the arc. But was he going to be the next crewmate? No, people said that everyone from Paulie to Blueno to even Rob Lucci was going to be the next Strawhat. This is stupid. Jinbe is the next Strawhat. People just want to fight against logic and reason until the last.
As for Hodi, he's probably going to collapse from ODing, and Chopper is going to end up being the one to save him. Being that Hodi's Bigotry is blind, he won't recognize Chopper as anything more than "Not a Fishman", and be forced to recognize that other races aren't monsters.
THe last part with Chopper may be plausible but Hodi is nothing like Franky when it comes to personality.I think the chances are very small but still there so I'm not going to argue of Hodi seeing that Chopper's not bad.
Franky cared for his namaka, it was why he went searching for Luffy after Strawhats attacked his HQ. Franky may have been angry at them for destroying a building but it was the injuries to his family that enraged him and made him go and find Luffy to fight. Hodi, on the other hand, does not see his crew like a family. Instead Hodi has treated his crew like fodder, going so far as using one to block Zoro's slash and then attacking Dekken to allow Noah to fall down on FI, even though his own crew is still there and gave no thought to them.
I believe that even if Hodi got over his hate, he still will not join because Hodi is treating his crew as expendable, just as Kuro did and Luffy hated that about Kuro.
