Oars the "Continent Puller"
I just heard about this theory related to that title and the part about Oars creating Wano really does make some sense to me:
When Moria takes Luffy's shadow to Oars, he (Edit: Hogback) explains the legend of the country-puller. A gigantic oni stole entire countries and brought them back to its own, creating a kind of jigsaw puzzle island.
Now, what's suspicious is that Wano is so neatly divided into its regions, and that these regions have differing climates. What if the rivers that split Wano into six is actually where the landmasses were fused?
And I know it may seem weird for different parts of the same island to have different climates, but we've seen Punk Hazard. Whether its the islands' magnetic properties (Punk Hazard has no magnetic field, but other islands do) or awakened Logias permanently altering them, the reason why the Grand Line islands have varying climates with possibly zero respect to latitude and longitude is a mystery, so this opens the possibility Wano could be a hodgepodge of former islands.
Now this would normally be considered as reaching, but there's another clue to consider - the island right next to Wano, Onigashima. We've seen its outline. It has a gigantic Oars-head. Oars was already gigantic by himself, but this skull here is about the size of the island.
What if Kuri, Ringo, Kibi, Udon, Hakumai, and the Flower Capital used to be separate islands, fused together by an oni who lived on Onigashima centuries ago?
And what if Kaido is a descendant of that monster?
