Who will he fight ?
The leaders get to fight the big names
I believe this incident led Kado to be suicidal and start attacking Navy and his rivals solo...getting captured 18 times and tortured.
He lost 7 times as a rookie probably
No wonder why he didnt want WB to die yet
He was also pissed when he saw Luffy went to BM island. He cares about his old mates and captain
I'm sure he was pissed when Shiki got captured too.
First of all, Kong was Fleet admiral back then!
Fleet Admirals do not participate until the very very end! They always send admirals instead of going by themselves.
Hell, even a war at their HQ made Sengoku participate at the very end not beginning. So, Kong is NOT included imo.
Also, Kong stated the two lead men who were doing most of the work in that era were Garp and Sengoku!
So, we got two main marines and two main Roger pirates.
One for each (Roger, Rayleigh, Garp, Sengoku vs Rocks, WB, BM, Kaido)
In case Shiki was also involved (since the spoiler is shaky, then Oda can add another member from navy like an admiral, or maybe Scopper Gabban)
Naturally it won't be Oden cause Oden joined WB first when WB was on his own ship.
Also, if Oda included Shiki who was from a movie, I see no reason for him to exclude Zypher. He could be a choice!
BUT if Shiki was not involved, then the four main characters from each side will be:
Garp, Sengoku, Roger, Rayleigh
Rocks, BM, WB, Kaido
