There are panels of them competing and arguing against each other. Stop with BS and read OP, not TP.
There is. He commented on their rivalry by a fan who said it's not just for gags as they take it seriously especially to hurt each other seriously. It's Canon and truth. Quit your excuses of denying Goda's truth.
They compete and never affect the plot. So its a gag. They never actually get stronger from so called competition. Neither one has ever commented on wanting to be stronger than the other. Nothing one does actually causes the other person to want to do anything in response outside of gags.
So its all gags. Sanji gets a bounty above Zoro he gets depressed coz it's vinsmoke written on it so it's a gag. Sanji tries to rub it in on Zoro, Zoro is with Hiyori and once again it's a gag that Sanji cares about the bounty. Sanji tells Zoro to get armor to avoid taking damage, Oda makes Zoro cut another cliff to chase off Sanji as another gag.
These are all the instances in just this one arc of Wano and they are all gags. I can go arc by arc if you want.
Then in the SBS Oda is asked whether Sanji put razor blades in Zoro's food and Oda says he did and that Zoro knows that there are razor blades in the food but continues eating it to test whether he's strong enough to digest razor blade.
This is the only comment of such a kind in any sbs. Are you actually saying this isn't any fuckin Gag? You read this comment and thought "yeah, Sanji seriously poisons his own food and Zoro seriously digests Razor blades... This is not a gag at all. These Aller serious literal things that actually happen and matter"
You actually think this? Fuckin get serious man
