Base King wasn’t looking too good, you know. He was trying to strangle Sanji and Sanji was more concerned about how Momo was doing. And King isn’t necessarily a swordsman either if he chooses to knock the ship down instead of using swordsmanship. Sanji was completely nerfed against base King. He isn’t looking good in base, but with his zoan Sanji could very well die (or win by very extreme diff) so it will be a battle for the ages
Sanji was going all out lmao, using his momentum generated kicks and King was casually blocking them
Despite Sanji having ludicrous durability suit, he was still feeling Kings casual Kicks
He couldn't even get himself out of Kings strangle hold and that is the reason why he had to give momo to Shinobu.
Then he got completely destroyed when King used a casual beat
From what I gathered it was
Hybrid Swordsman Wildfire King mid diffs hybrid swordless non wildfire King mid diffs Base swordless non wildfire King mid diffs RS Sanji who mid diffs Base Sanji who is equal to Vergo
So basically King would overall neg diff an army of Vergos
