After reading some threads of who is stronger between Sanji and Zoro, I remembered Little Garden where they both hunted dinosaurs to bring back the biggest and see who is the best.
More then 800 chapters later we arrived in Wano and guess what…there are dinosaurs.
Well they are humans with zoan devil fruit powers. So far it seems Sanji already beat one (Page One) and is now fighting X Drake.
Anyway the 2 strongest are King and Queen, as we found in latest chapter that Queen is a Brachiosaurus.
Both are Kaido’s strongest Disasters, just as Zoro and Sanji are Luffy’s strongest crewmates. My guess is that Zoro and Sanji will fight against them. Sanji vs King and Zoro vs Queen maybe. Why not Sanji vs Queen? Well, King is a flying dinosaur and Sanji can fly, Zoro can’t. And a queen is feminine and Sanji doesn’t fight women. And last, King and Sanji both seem to be using fire.
