>>43344211If you think about it, Swanna is the only birdmon that's anatomically correct. If you see it opening its wings in its BW sprite animation, you'll see it has big, strong arms, like real life birds do, while all other birdmons have twigs for arms (you can notice that more on Pidgeot, Fearow, Articuno, Ho-Oh, and Braviary) and they would break easily if they tried to flap their wings in real life. Pelipper doesn't even look like it could possibly function at all, it has no neck, no skull, its feet are coming out of nowhere, if it tried to stand it would fall over, same thing with Togekiss.
