The title says it.
I decided to make this thread to keep track of my theories and post misc. stuff. I hope you find them interesting.
Urouge & Enel
This is a theory regarding the issue of Urouge's wings.
As you can see, Urouge had Skypiean wings as a child and has Birkan wings as an adult. I very much doubt this is a mistake. It's not only the wings, he has skypiean clothing and hairstyle as well. So here goes:
Urouge was fascinated with "vearth" (You can see in the picture he's holding a rock). But the only place in the sky where you can find it is the Upper Yard. So he used to disguise himself as a Skypiean to get there (his wings in the pic kinda look like they've been bent up). I also think he's the reason why Enel is so obsessed with vearth. He probably told Enel stories about it. Then, maybe after or shortly before Enel destroyed Birka, he decided to come down to the Blue Sea. Dunno what his current relationship with Enel is. Is he seeking revenge? I don't think it's a coincidence he was trying to land on Raijin island.

Jack,Queen, King and Joker WB=King, BM=Queen, Kaido=Jack, Doflamingo=Joker.
Marco called WB "King", after he blocked Kizarus lasers. Not "Ō" but "Kingu" (at least in the anime). Like Dofla is called "Jōkā" and Jack is called "Jakku". Could be just a figure of speech and a coincidence, but it could also be another case of Oda's foreshadowing.
Big Mom's crew seems to an "Alice in Wonderland" theme, so the nickname "Queen" would suit her well. (As in, the Queen of Hearts).
That leaves Kaido and Shanks, and the way those guys talked ("I'm going to inform Jack" "Won't that be bad?") makes me think Kaido. I guess it could another powerful pirate too, though…
New World Island Collection
! The following places have been named:
Elbaf (is it in New World?)
The island I've marked as "Mystoria island?" is the island where Kid was seen before the TS. It would make sense because Kid couldn't have gotten very far at that point, and the island looks kinda "mysterious".
! DF Collection
More to come, I guess.
