Just imagine if they give Luffy Sin's mechanic about needing to eat meat to keep up your power.
That'd be awesome.
There's so much they can do with the crazy cast of One Piece. It'd be a truly unique fighting game.
After having a browse at some Wano theories, it's got me all hyped and I'm trying to picture how the fights would go. What do you guys think of -
Luffy, Law, Kidd, and Drake vs Kaidou (with Luffy going Gear 5th and potentially dying, allowing Law to sacrifice himself using the Immortality Operation to save him)
Zoro, Killer, and Kin'emon vs the Shogun (or maybe Zoro solo, as he's in need of a tough fight in the New World)
Hawkins and Apoo vs King (I feel these two shouldn't be underestimated. If Luffy and Nami can take out a Sweet Commander, two Supernovas should be able to take out a Disaster, though it'll be a difficult one)
Nekomamushi + Inuarashi vs Jack (to avenge the Zou incident)
Marco vs Weevil (for obvious reasons)
Im struggling where to put Queen. I'd say Sanji plus help if it turns out he's an Okama, but if it's a woman I'd say Jinbe plus help. I'd rather it a woman too, a sausage fest would be pretty dull.
I'm guessing they'll be seven samurai as enemies too due to Oda's love of references, so there's many potential match ups there, allowing one for Killer and Kine'mon if Zoro goes one on one against the Shogun.
I also feel they'll be a spat between Kidd and Apoo, as it's been foreshadowed since their appearance, and Apoo has back stabbed the Alliance. He's a crafty character though, so I fully expect him to turn again.
Then again this is Oda and everything I predict will likely be turned on it's head haha.
