The chances that this Shantiyen is a Leviathan are slim to none in my view. Sure it's bodyshape is similar to that of Lagiacrus but the fact that its flying, has a wind barrier around it like Amatsumagatsuchi and Kushala Daora, and that it showed up in a thunderstorm surely can't be a coincidence. Also it's design very elaborate(too elaborate if you ask me) and fantasy-like for it to be a common species of monster. I believe it is safe to assume that this creature is an Elder Dragon.
