I'm not saying a dragonfly. Not the type after it. Seeing as we know so little about them, we just have to speculate and so what I would like to see would be these large dragonfly type units. Essentially just a serpent body with 4 wings. You never know.
And how would a normal (my norm, so western dragon) dragon defend itself? Either firey-breath, long claws, big teeth etc. anything really.
