@Strelok:
And Ace died being Logia, so losing an arm is no proof. And you can't prove that Kidd is not a Zoan or Logia. Blackbeard is Logia, but he can't transform, can he? And we still have mythical Zoans. We know he is Paramecia the same way we know that Buggy is a Shichibukai, but some people still scream UNCONFIRMED like a menstruating teenage girls.
Buggy became a Warlord, because he recieved a letter, the Government needed Warlords, he had the reputation to become one, and Buggy would not let a chance like this slip. This is shounen-logic. Oda would not include the scene if not to show exactly that he is a Shichi.
The only reason Blackbeard is logia user because he says so, that pretty much CONFIRMED it. Otherwise, his DF characteristics are paramecia's. That's why he said yami yami no mi is special. In special it means that it's different with other logia DF.
It's not that logia user cannot be harmed. There are haki and seastone, which enable access to the real body. Or by using the weakness of the element as we have seen with Luffy and Enel and with Akainu and Ace. Perhaps we also have seen that full body shock/impact can hurt logia user (Luffy hit Smoker and Ace, Jozu hit Aokiji and Croc), although the evidence is quite subtle and debatable, and Oda has successfully dodged it when asked about it. Quoting from you:
@Strelok:
He doesn't add RANDOM scenes for shit and giggles. :ninja:
But Jozu lost his arm by none of above methods, unless you are saying that the weakness of diamonds is cold, which is possible, by the way, if Oda says so.
And Kidd, well, why don't you tell me what makes you think he's a logia or zoan user? Because the premise of paramecia is if it's not a logia or zoan, which he hasn't been shown to be one. And that is why I said "almost certain", because although I'm sure about it, it has not been confirmed. Anyway, have we seen a solid element logia? (don't say that sands are solid) And what mythical zoan is magnetic? The Eleven Supernova v.s Marines chapters have pretty much showcased the abilities of the the Supernova. What makes you think Oda is keeping it from us if Kidd is really a Logia or (mythical) Zoan?
Look, all I'm saying is that until it is stated in the manga, it is not confirmed. I also tend to think that Buggy is a Shichibukai now, because there was the letter that suggests the idea. But again, he hasn't been confirmed to be one. Oda has surprised us many times. His logic is not always shounen-mainstream. Though, again, I believe that Buggy is one.
Summary: There's no evidence that Kidd is logia or Zoan, or should I say, the evidences so far suggest otherwise, that's why he's a paramecia. Buggy receives the letter which suggests that he's a Shichibukai now. Both haven't been confirmed.
