and how come kaidos belly in dragon form looks like vestral scales that can be found in snakes and lizards and not a "clams belly"?
and where are you seeing camel head, demons eyes, tiger paws and all that shit?
Yes, kaido is based on chinese mythology, but oda is clearly not just copying the shit you listed. And there is absolutely NO differentiation between the scales, so assuming there is a difference between them is wishful thinking at best.
If Kaido is based on Chinese mythology dragon like you agree, then Oda is copying the shit listed right? To a certain degree because the physical make up of Kaido bears huge resemblance to the Chinese dragon and azure dragon.
He has the cow ears, deer horns, eagle's claws, carp scales. When they say clam belly, they mean smooth like a clam with the visual lines, as opposed to the carp scales. When they say camel head they mean more like lumpy like camel. And I already mentioned the eye thing since even Orochi snake df form does not have snake eyes.
Even still, I only brought it up to show what Kaido dragon is based off and how 'distinguished' the carp scales are in it's mythology/folklore, which bears credence for speculation.
That compounded with the fact that Oda:
1. Chose to draw the slash across Kaido's blue larger carp scales, not done before
2. Chose to highlight that someone actually cut through his scales.
Means that speculating that Kaido Carp Scales are the toughest defense on his body, is more than just wishful thinking.
