2nd Who would be the most suitable for each fight???(Only for Aokiji and Kizaru cause the thirds abilities are unknown yet)
I believe that sanji chopper and luffy would be a great team for Aokiji:Franky could breathe fire in order to melt some ice and when he uses his break to ice to avoid attacks Aokiji will face the danger of becoming water , Luffy can go to high temperature with gear 2nd so with a small effort he could melt some ice , Sanji wouldnt be affected by the ice armor due to Diamble Jumble and chopper is just for brute strenght.
For Kizaru:Robin could try to get a hold of him and zoro , nami , and ussop beating him in every way !!!(I dont believe this could work actually )
