At this point in the story while the strawhats fighting all 3 of the other emperor crews in order 1v1 sound cool and all I doubt it’s going to happen. Mihawk even hinted that the battle for the one piece will involve all the emperors fighting at once
Main 2 reasons being simple
- I don’t think each of them is going to get their own arc dedicated to them
- Cause that’s at least 3 more arcs not including a post one piece pirate king one
- At this point 1 emperor going down just isn’t that big of a deal
- In wano we had both kaido and big mom fall and in egghead we might see the fall of both kizaru and Saturn. While yes obviously beating an emperor is impressive the stakes aren’t that high. Especially now that the strawhats themselves are an emperor level crew
Also the final battle involving luffy shanks and Blackbeard could be really dope imo. Shanks and Blackbeard being opposites of each other and Luffy somewhere in between
- Shanks grows stronger through training/advancing his haki, Blackbeard through powerful devil fruits, and luffy relies on both
- Shanks might get Uranus (Heaven), Blackbeard Pluton (Hell), and Luffy obviously Poseidon (sea)
- Shanks is connected to the celestial dragon, Blackbeard the d. Family, and imo luffy might be both
Also kinda side note
While kid and law are pretty much out of the race for the one piece I wouldn’t be surprised if they at some point even if it’s at the very end play a role in getting back at shanks and Blackbeard. They’re not going to defeat them but they could still do something as a form of payback
