From a non biased perspective from a sanji/zoro stan, or any other OP fan can you please give me an explanation after all we have seen sanji do from Dressrosa to WCI, how his powerscalling works?
1- one simple kick using Hell Memories cooked a mountain sized opponent.
2- Even with a cracked shin goes toe to toe not losing an inch with Vergo(who can combine CoA and Tekkai similar to how Katakuri combine his hard moshi and CoA)
3- Tanked a meteor destroying move with his bare body from Doflamingo without much damage.
4- Doflamingo was forced to use Parasyte(a hax move that stopped Jozu a YC) to immobilize him.
5- One shotted a headline in Zou
6- Beat Yonji, an inhanced super human, off screan.
7- Judge was forced to use dirty tactics to deal with him and still didn't beat him.
8- Even distracted he could dodge FS user Katakuri.
9- Him and G3 Luffy blocked Big Mom.
10- Speed blitzed Oven.
11- Could tango with Daifuku's giant genie
12- Could lift a giant cake and jump with it before throwing it away like nothing with one leg.
13- Played around with Page One, a F6, while testing his RS
14- unscathed even when hit by X Drake in his zoan form that has the biggest strength.
15- Tanked Kanjuro's full on attack that destroyed ships with his bare body to protect Nami without any injuries.
=> He's more than ready to face a YC like King or Queen.
