I think Kaido's body will be bulkier in the translated scans. Because in the raws the double spread isn't cropped well.
I like Kaido's hybrid. The reason there isn't much difference is, because Kaido by nature is a bulky giant with a dragon tattoo. But logically, this is what hybrid looks like.
Though the face could have been better
Like more dragon-like, dragged out.
Like here :
That's a nicer face imo.
