You kids still dont get it. Sanji not being a supernova has nothing to do with bounty.
Oda could easily make the minimum bounty for a WG supernova 150 mil, so only Luffy could be a part of it from the strawhats
Oda could easily make the minimum bounty for a WG supernova 80 mil, so Sanji could also be a part of it
Oda wanted to group only Luffy and Zoro with the top dogs of their generation. Sanji has no business here.
On topic, its not impossible for Sanji to take part in the battle against Kaido, which is true for the rest of the strawhats also
I hope all 3 of the monster trio do damage to Kaido. It is telling that Oda makes them a monster trio but only gives Luffy and Zoro haki based improvements. Its a bit unfair and biased. It seems so biased that maybe Oda slipped Queen's comment in there about Zoro and Sanji still being 2 & 3 because its not so obvious. It seems like he's still got Sanji doing his timeskip/separation training. But its time they start giving Sanji his due. Even his bounty is apparently a result of him being part of the Germa and them losing their status.
There's nothing unfair about Sanji not being on Zoro's level. He is the cook. In fact, its unfair when the cook becomes as good as someone whose sole purpose in the crew is to fight.
