It doesn't go that far buddy
Sanji never gets obliterated by anyone lol, at most he gets a bit hurt but still looks good and puts up a fight, sometimes acknowledge or intentionally put in a situation where Oda thinks he is nerfed and can justify an L
Bruh
Just Saturn presence made Kiz, luffy, zoro and jinbei surprised.
He is literally giving evil vibes...magic circle, haki oozing out, dark presence....
Oda will hype Saturn and it was given from the beginning as this was Gorosei first arc.
And, oda already set Sanji vs Saturn - not just with their title being common but with bonney as Sanji will try to save her again.
It's not about obliteration but having a set trend post TS - sanji becoming hype tool.
In this case he is again set to be one with oda deliberately keeping both zoro and luffy out of equation
