One thing im 100% SURE.
NONE of the F6 Will get One shoted, not even close to that.
Lots of people here are sleeping on them. LOTS.
Ulti that is not the strongest F6 made luffy Go gear 4 already. No Wonder Apoo is BELLOW them.
Whos who and Sasaki where more than Fine to fight Calamities, oda didint put these two so confident for nothing, and we still dont even know their fruits, their feats Will be insane and people here like i Said are sleeping in the F6 especially these 2.
I woundnt be SURPRISE at ALL If king fights marco and zoro before Go to kaido fights whos who that Will prove to have calamitie lvl. Franky wont won against Sasaki by any means, Denjiro Will come and have the final fight with his "friend".
