There will be spoilers so if u wanna know what I gotta say keep reading:
So Zoro just discovered his conqueror's Haki, and I wasn't too surprised by it. But that brings up another question, does Sanji have it?
Because a person is born with conqueror's Haki, and Sanji definitely has a better background and heritage than Zoro. Luffy has it bc he is the son of the leader of the Revolutionary Army, and Ace has it bc he is the son of the pirate king. So as long as Zoro's heritage isn't revealed that puts Sanji in a more "royal" or "higher" position than him, so that led me wondering - could the Monster Trio all have conqueror's Haki.
Bc Sanji is the son of the leader of Germa 66, the man who is very close to conquering North Blue, and they are of royal blood. So if Zoro could have Conqueror's Haki within him I see no reason that Sanji couldn't
Let me know in the comments on how you think about this
