this is pure BS, considering Sanji would hit gunko him and zoro would no way in a hell they'd lose. They'd just keep bitching her and let her regen just like how they attacked the gorosei in similar situations and actually were way more usefull than that fucking fat fish
Against someone like Gunko, zoro and sanji is in the same bracket of power as Jinbei.
Even if they attack her, all their attacks are going to be deflected and will be hitting each other. They are completely outmatched in terms of stats.
You bring up the gorosei here as if those old bums are any stronger than the HK. HK are stronger than the Gorobums.
