Usopp, zoro, sanji, Franky, nami, robin, jinbei, vivi, chopper, brook vs Big Mom

They talk to Luffy, Law and Kidd first for intel. Get 7 days to prepare. They know which way Big Mom is arriving from. Takes place on Egghead Island. Let's add a forest to the island too.

Then they fookin fuck big mom up yeh?

They win. Sanji and Zoro do most of the work, Franky's Radical Beam should do good damage if she isn't paying attention and doesn't guard with Haki. Usopp, Vivi and Chopper are just in the way.

Big mom wins
