He did rejected the suit but germa science is genetic enginering so who knows maybe sanji still have another innate ability?(as long as its not CoC out of nowhere) reiju still poison resistance even without her suit, IMO the suit is just to accelerate or enhanced their innate and adding ability...
yups i knew it, just another bonney V2, candel was sick because shes pregnant not that fog. if bonney didnt run away they might groom her to be the next HK replacement
same logic should apply to zoro or sanji why u think jinbe can't control his fist? hes supposed to be the most experienced fighter on this crew, his grip alone crushed who's who coated hand. its either sanji get to the robin first or oda nerf jinbe so the trio power scaling isn't disturbed
