Let's go! Long thread ahead, but first and foremost, Marineford's impact thematically on Wano cannot be overstated:
Kaido's challenge to Luffy verbalized what Whitebeard wanted to see: What kind of world will Luffy create?
His clash against Kaido was initially kind of confusing for that reason! Remember, Luffy's Golden Rifle was already perfectly inverted on Fishman Island - the Red Hawk against Hody.
But the set-up didn't echo Skypiea like the above!
It's also interesting that Kaido sheathes himself in flames like Magellan wrapped himself in venom. Both are capable of melting their surroundings because of the attack, but Kaido's dialogue reminds me a lot more of Enel's - reminding Luffy of the history at stake.
It's not an inversion on the larger scale of the series from what I can tell (I'm open to suggestions on this by the way!) but even tho Hiyori/Orochi/Kyoshiro clearly pulls from Kaya/Kuro...
...I love the inverse symmetry between Hiyori's "death" and Orochi's death.
I for the life of me haven't been able to pin down Kaido's backstory just yet, but I did find it kinda interesting both Kaido and Ace were fast-rising youngsters who were asked to join larger groups.
When Wano originally began, I thought for sure that Kaido would have a panel similar to Whitebeard's below. I haven't seen it yet, but I get the feeling its inversion might be similar to Kaido and Rocks' relationship.
#ONEPIECE CHAPTER 1031 INVERSION THREAD: Big Mom and Moria strengthen their connection!
At the end of TB, Moria essentially kills his subordinates by using Shadows Asgard. Big Mom takes souls from around her and gives life to inanimate objects before powering up.
CHECKERED FATE THEORY THREAD: If you're coming here from @TotallyNotMark's video, welcome aboard the insanity of spotting inversions throughout #OnePiece canon!
Here we'll shine a spotlight on the inversions not covered in the vid - think of this as a visual aid to the word doc!
I feel like the easiest way to start this entire thing off is to talk about island structure. That was what really kickstarted this entire concept.
The video already touched on Onigashima and Marineford's similar structure, but we'll place both right here as a starting point.
The video also mentioned Impel Down's general structure as well - the interesting part of this structure comparison is that Oda is blending concepts together. More on this in a moment.
