His sibling are trash lol, Sanji was above them since WCI. They were pierced by special bullets, but still bullets.
Queen, a super scientist, has a fodder sword...ok bro
And he might had coated invisible Haki. Scabbards used many times Haki but it was invisible.
If Sanji is weak, what the fuck is Zoro who was blasted away to the edge of the island by a named attack of King while Sanji was blocking casually Queen's named attack in Base
? C.L.O.W.N.
Hardness boost is irrelevant to Sanji, Queen didnt touch directly Sanji until he started to move wrong because of his inside transformation lmfao. Sanji could have blocked, parrying and dodged all of his attacks until the end and finish him after hours of fight with accumulative damage, like Luffy with Katakuri. Sanji was already a commander lvl without the boost clown.
Bullet penetrating his skin is irrelevant, no one can block bullets with their bare body aside from people with special hard body like he now, Kaido or Big Mom. Zoro would have his skin penetrated as well, did you forgot the nails of Hawkins? What in the actual fuck is that any relevant powerup lmfao when the characters can tank direct slashes to their body without being sliced in half which can cut building and more?
What a fucking C.L.O.W.N.
