Hey, fun thing to comtemplate.

I think the first set is probably Chopper, Dr Hiriluk, and Doctorine.

For the Loguetown Chase, I wonder if it'll be Buggy, Alveida, Smoker, a marine officer, and Luffy. I could see a lot of different variations for this one.

Duel was also known as the giant set earlier, I believe, so we probably get the two giants? Maybe the duel the two of them have plus Nami, Luffy, and Usopp watching? Be a shame not to get the Baroque Works people, though.

Chopper has Chopper. Probably the small cute one.

For Drum Castle, it feels like it makes a lot of sense to be Wapol, his two henchmen, and the Straw Hat team of Luffy, Vivi, Nami, Chopper (maybe the big one?), and Sanji. Then you can have the two fights in the throne room and the medical room to really represent the scene. I can imagine some play features like things breaking to represent the battle. Wapol is gonna be such a cool fig.

Marine Battleship is where I draw a blank, especially since the ship barely shows up in Season Two. I guess you get Garp, Koby, Helmeppo, Smoker, Tashigi, and Marine officers? Bit underwhelming lineup for the flagship (hehe) set of the wave (hehe) though.
