-At the end of the chapter, Queen attacks Sanji with his sword but it breaks when he touches Sanji's body.
Sanji breaking Queen full swing sword with his body alone is a insane good feat and in this case it doesn´t matter if Queen use haki or not duo multiple reason.
First yes we see how Luffy breaks Rebecca sword with haki, but again the one who swing the sword is fucking Rebecca.
Physical power matters too, I mean Luffy hands where hurting even though using haki against Kaido non haki swing because of the physical power alone. If someone has a great physical power, he can cut and hurt the opponent though his haki and we see that in the serie multiple times.
Sai brother Boo haki axe get broken by Booby funk body alone:
If Zoro would swing that axe, Bobby FUnk would be one shotet and Zoro wouldn´t need haki to cut this fodder.
But in Boo case though him using haki, he couldn´t hurt Bobby Funk because his physical power was greater then his haki.
We have a another example with Law cutting though Doffy haki without using haki:
Doffy use haki, but he still get cut by Law attack, meaning his haki was not strong enough from getting protected by Law physical swing power. It shows again if you not having a greater physical power, haki alone can´t help you.
That was also the case with a bawler like Katakuri, his CoA was stronger then Luffy, yet Boundman easily overpowered his supreme Haki duo the physical power difference.
And now the same apply to Queen vs Sanji,
Queen in Base could knock down a top flying six member like Drake easily down with his sword:
Base Queen already put Drake with a swing of his sword down, his physical power is insane.
I don´t wanna even want to know what would happen if Queen attacked him with hybrid sword swing.
Sanji body breaking Queen sword after a physical swing is actually a insane durability feat and im not sure if his siblings would break it like that too, in case Sanji could hurt his brothers already with a base kick, bent their face/head, their durability get broken by Perospero candy, Ichiji was knocked out by base Katakuri in seconds.
And Sanji body just fucking break a full swing of hybrid Queen, a very strong commander..
Just think about this and realized how incredible this feat actually is.
We see how powerful these zoans been, Queen having a solid sword doesn´t matter, the physical power is important and he didn´t cut Sanji Exekelton.
This going be now interesting to see how Queen deal damage on Sanji hard durability, im not even sure if Sanji yet use his RS who even push more his durability.
