Just let me make it clear first that I am not against the idea that Kaido may be tech based, that would be cool.
I am against the idea that he has to be tech based without seeing more fo Kaido. The difference is assuming something is fact without seeing Kaido himself. Fans assumptions have been proven wrong before in OP.
@The:
Whitebeard didn't have a giant moving, metal domed city that looked extremely sci-fi inside though. And we saw much more of Whitebeard before any cyborg crew member, so assuming he wasn't tech based is logical.
How do you know he didn't? We only saw two cities/villages that were part of his territories= Fishman Island and Foodvatlen. We know he had more than that as Blackbeard took over much of it.
Whitebeard had about, what.. three apperances before the war, (meet with Rockstar, then Shanks, then Ace's flashback) and the scene where Vitan appeared was shortly after Whitebeard appeared at the War. Sure, thats more than Kaido but it doesnt' mean we had time to get to know much of Whitebeard esp since his only apperance on land was when Ace fought Jinbe, no city in sight.
As for Kaido(u), EVERYTHING we've seen of him so far points to that. From the cyborg to the giant moving, metal city etc. I'm not saying he is, but, what we've seen of him so far–the small bits--hints at it.
And what have we've seen of Kaido?
Are you including the silouette when Garp talked about the Yonkou at Water 7? Besides that and the scene of Scotch on that 'certain winter island" Kaido's fond of, I don't recall any other appearance. If there are more, then obviously I forgotten and I need to refresh my memory, please give a link to the chapter.
What city is that? I went to see if I missed something when Scotch was introduced in ch 595. I had to resize bigger and sharpen the image, but I do see some buildings behind Scotch and tress covered in metal plates. Seriosuly, we cannot tell if the building are metal or stone in the picture, and certainly mothing in that picture suggested a moving city. There looks to be some metal posts on top of those black & white striped mountians, but the mountians themselves don't look metal…tent-like yeah but metal nope

I do not remember Oda showing anything else in the manga. If it was in the anmie-only then that is not canon, but a made up filler. ITs not fact until ODa shows it in the manga or he presonally mentions it in other source, like an interview or databook (oh wait.. those don't count since some people at AP always says it his assisants that does them and therefore info in them are possible to be inncorrect, and well we DID see some big mistakes in the Deep Blue like wrong flag)
