@Joy:
Again visually Oda has completely failed to represent BM as a Yonko.Zoro has better feats.
Has Zoro ever destroyed buildings just by punching them? Has he damaged a real fortress with his fists?
Has Zoro nearly killed several people while sleeping?
Has Zoro overwhelmed dozens of people with his voice alone?
Does Zoro have Conqueror's Haki?
Has Zoro blocked a sword with his bare forearm, without using Haki? A giant sword, no less?
Does Zoro subconsciously strike fear into most people wherever he goes? (he's getting there, but Big Mom has quite a bigger scope in that department)
When Zoro was a young child, he defeated strong guys at dojos and took their flags. When Big Mom was a young child, she razed villages and got a bounty equal to Luffy's before she even hit puberty. Zoro eventually met his match in Kuina; Big Mom so far has never been shown outmatched by anyone, with her presumably only equals being the other Yonko. Even the Pirate King himself was never stated to have beaten her in combat; he instead outwitted her, stole her Poneglyph, and ran. In contrast, Kaido was defeated 7 times and has a giant-ass scar while Big Mom's only received scrapes when she goes into a breakdown. If Kaido's having an emotional fit, he swats people with his mace, and if Big Mom has one, she either completely debilitates you or pulls your soul out. Why does Kaido get a break from you?
I know what needs to be done. We just make Big Mom go through a sex change, replace all her fat with muscle, replace her happy pink sundress and hat with a tough-looking loincloth and a fu manchu mustache, dye her hair black, give her horns, and have her rule over a cold and unrelenting winter area instead of a sweet wonderland. And give her kids animal powers instead of food powers. It's perfect! Oh, and of course we can't forget that one special feat, the one that shows that she can pull things off that should be beyond a mere human's ability, something that sells her sheer power.
…After a long call with my agent, I've been told that the last thing has already happened:
!
Honestly, what do you want to see from Big Mom? Attacks so devastating that they instantly knock out their targets, no matter their defenses? How, then, would the heroes survive other than plot convenience? What would it take for Luffy to pass the threshold of Yonko-caliber strength if even his most powerful attacks are akin to an thrown pinecone in front of a Yonko? One Piece does not have rigid power levels where if someone is stronger than the other, then the other can pose no match or threat to them at all. Luffy and Sanji have trained for years to survive in this ocean, and have shown that they can indeed do so, and even if they can't beat Big Mom (which will almost certainly be the case), their training should at least be good for something.
Zoro should marry Big Mom.
