I am a absolutely amazed I read this entire thread and didn’t see a single Luffy
The idea Big Mom was fumbled is just wrong, she was a monster who still only lost because she got blown up by an entire basement of explosives and then fell into a volcano, which she survived. She basically walked through Onigashima just like Kaido. Her character is insane, there’s no precedent for it, how can Oda fumble it? She’s one of the most unique characters in the story.
