-Sanji neg diffed 700 mill bounty perospero
-Saved Momo vs King
-Saved Chopper from queen, saved random ass ***** from the live floor
-Will probably beat queen solo and than tag team vs Kaido
1.3billions+ bounty is more than justified at the end of Wano
And this is in the worst case scenario, Sanji does not even need to face Kaido, he still gets 1.3b+bounty just from what he does like now.
Sanji is strongest in the alliance after Luffy, Marco is good, but he is not main character, even zero will probably be stronger than him EoW.
