Personally, I think any of them could’ve replicated that feat
They literally all have identical durability
Yes, all of them should be able to do so. Also, even if one genetic material produces better outcome than other, a good developer would implement those elements in all of the subjects. Scientifically viewed, they all should be equally powerful - basically the maximum of what VP could get out of the starting material. Let's see how that develops. I don't expect Oda to go this way, there'll be a hierarchy since it's typical Shonen stuff.
I also believe a hotter flame could also possibly bypass Lunarisn durability
Hard evidence > 'Believe', 'could also'
No it can't unless proven otherwise. Sanji will have to pull this one though. I hope Oda lets him.
no, its not confirmed Acoc can harm Lunarian durability
Zoro defeated King in speed mode
Said hard evidence:
King is in flame Mode. King blocks zoro's attacks. Attacks that supposedly are zero effective against flame on mode. The topic is addressed directly on panel, King gives no answer other than looking afraid.
Same king pre adv CoC zoro
Not enough for you to verify?
