YONKO RACE TO ONE PIECE
Luffy vs buggy vs Blackbeard vs shanks will be all out brawl for one piece rather than luffy beat shanks single separate arc or something else.
This battle Royal style as finding one piece . So luffy can battle shanks, buggy , teach at same time . Zoro will fight shiryu , mihawk , Ben beckman at same time. Same thing happen to crewmate s fighting each other at same time . It won’t be traditional 1vs1 fight but rather pirate fight style in chaotic way . Like marineford style.
Cross guild will clash other yobko crews. Starwhats crew will clash other yonko crews.
You can argue luffy will defeat Blackbeard but buggy somehow made to land one piece first and claim it as your theory .
‘You can argue anything you want on four yonko crew with your imagination. Zoro will face shiryu and mihawk at same time, sanji will fight mr.1 , crocodile , Ben beckman. Jinbe face crocodile, etc.
FINAL WAR BOTTOM PANEL
The bottom down seem scream final war , but final war will happen to affect entire world , not one island . Think of shouen epic final war as it happen entire world . Like torkio final arc, naruto final war . Island getting blown up or destruction island level as it like Tuesday . The red line is definitely get destroyed. There is might be plug to pull out to solve flooding issue affecting one piece world. Marineford. On steroids.
However , theses character are not guaranteed as fighting for one thing goal but follow different goals.
‘Cody - want to stop luffy
Kuzan- whatever he has some idea in his head
sabo- declare war on celestial dragons , he attack gorosei and Imu first before any characters
Garling - probably same goal as celestial dragon, gorosei , but he probably has own ideas
Holy knight/unknown guy with sword- unknown
Dragon- plan to overthrown celestial dragon, revolutionary leader
Imu- King of the world, want lily , want to removed people that threat his power ruling, want to keep his identity secret
Akainu- Fleet Admiral , hates pirates, want to kill luffy the most
Lot of characters I list have different goals, agendas, etc. Technically Cody would be get involved in one piece race if he want to stop/fight luffy . So it is difficult to predict how oda will handle characters .
The final war will happen after one piece is found . When one piece is found , it would be huge power grab from all sides .
