So just as a ref for all of my interactions……This excellent drawing by my friend @sendingstone / Vernal is what Alwin actually looks like. He doesn’t have these features in Pokéverse (yet) because Tea did not envision Wyverians with more draconic features, but mainverse and fantasy verses are Free Real Estate, Babey and so I’ve decided to give Wyverians more draconic features.
Apart from some very obvious draconic facial features, Wyverians also have tails, retractable claws, and scales all over their bodies; their feet are also definitely scaly, with scales blending with skin at the calves before turning into feet that look purely reptilian. Alwin’s tail has poisoned spikes on it like a Rathian because, also according with Vernal’s lore, different Wyverians are aligned with different wyvern species depending on their location. In addition to that, he has some bioluminescent spots along his body because his father being from Nua Te is an Astalos-aligned Wyverian.
Why do I headcanon this? Because Capcom were cowards when it came to creating a race of fucking DRAGON people, that’s why. Like what’s the point of making an entire wyvern-aligned species if you’re just going to give them pointy ears and funny legs?
