The three strongest..Diamante which I said before looks lazy but probably is a bad ass beast in the arena. The blob guy who gets too close which is the clubs dude and spades..who seems to be the mystery face. I said already that SH's would take a whooping this arc if they didn't receive actual help...Law thought he had this game planned out but he didn't foresee Dofla's importance...and that was his biggest mistake. If shit goes wrong for Luffy who is above the hidden factory...Sh alliance group will need some serious saving. Law has to go meet his own crew so unless they somehow show up..the actual coliseum combatants/prisoners just may run a muck and join SH's. Though the biggest strain will be restoring Rebecca's honor and rightful claim to her throne. Once Rebecca actually successfully pulls off the coup de ta....she can unleash hell on Dofla supporters. SH's will soon confront the scary toy master of the DD family. Beat his ass and reverse the oppression that has taken place. Fujitora really needs to put aside his loyalty and alliance with the WG and help out Law who is actually doing good.
i just realized technically Dofla is taking back what would of been his if his* family didn't abdicate their throne of Dressrosa. He is claiming what his family left behind. Even though the Riku kingdom was established as the new royal family....Dolfa turned the citizens against them in order to reclaim the deserted kingdom.
