Dragon should fight Imu but I don’t believe he’ll be allowed to defeat them, possible fight w Kong is on the table as well maybe to hype him before facing Imu. I believe Luffy should be the one to defeat Imu because he/she is seemingly the ultimate enemy of the world, him being Joyboy/embodiment of liberation and freedom helps his case. Luffy should also fight Akainu. I believe Sabo will finish the fight so Luffy can save his strength for the main enemy of the war (Imu). There are ppl that don’t understand how Sabo will do it, that’s on Oda, I don’t have a problem with it. I honestly believe Sabo was literally created for the purpose of defeating Akainu and I can’t imagine a reasonable alternative. I get Dragon has been saved this whole time to make a major impact in the final war and he created the rev army to fight the CD’s but this is also a shounen manga, I have never seen a side character defeat the main villain of the story and I don’t see Oda having a tag team play out, he didn’t even allow it to happen for Kaido’s last stand. I also understand ppl that believe Blackbeard is the true villain and I respect that, but I don’t believe he is.
