I have this dream........a highly unlikely dream........that crocodile will get a major power up and end up killing doffy, just because I think there are too many possibilities for people to kill doffy I mean law and luffy and kaido or even fujitora so I think it should be some unexpected person to swoop in and take the kill. We have seen croco and doffy have a prior interaction that made it obvious croco didn't like doffy and I think most of one pieces fanbase would love to see crocodile get stronger and take out a big one.
