@Yamue maybe it has to do something to do with environment or the amount of probably the amount of bug powder he received, or bug powder develops insect features in the the best and most efficient places and because of that he got less prominent features, or it could probably have something to do with the bug powder only developing the relevent features of a dragonfly, though again it could be releated to evolution but i think i'll doubt that one (evolution could also be conditional like depending on the environment youre in)
