I wonder if Raizekusu being separate from other flying wyverns we could see other wyverns from the same type in the future, these insect-scaled wyverns.

I remember that there was a concept art of an insectoid wyvern in one of the artbooks, they probably were planing these things way back but never got the chance to put them in the games.
