[QUOTE="ShadyOjiro, post: 1981945, member: 60"]It's the same for all , remember it's genetically edited.
You can't train an exoskeleton.
The difference of his brothers and him is that Sanji can add COA that's why his defense will be better than his brothers.
The healing is part of it too remember Niji recovering from sanji kick on his chin or Reiju bullet wound( well the bullet took time cuz it's was specifically for germa).[/QUOTE]
It is not the same for both since they got it at different stages of development. Just like how Deku building up his base made him a better holder for One For All and the Inverse for Shigaraki, same thing here.
And recall, this is a hypothesis, we will not have the full picture until we end the fight. But Sanji as described is ahead of what happened with the others who featured no on-screen regeneration, from Sanji's kicks at least.
On the other hand, it does explain how Germa recovered so fast from the raid bullets and Katkauri/Big Mom. Niji did fix his jaw back into place, so nothing a bog standard human here on our world can't do..in theory.
