>>54027796Dragon Pokemon are reptilian which is the most chuuni class of animals; they will almost automatically be cool. The ones that aren't cool generally aren't popular. The ones that are weak are generally less popular than the powerful ones too.
Your list indicates an appeal in things that are based off things that aren't exactly draconic, so a creativity in their inspiration. Garchomp for example is a landshark with prehistoric dinosaur traits. It looks dangerous and untameable.
Tyrantrum is a dinosaur and is less popular because it is just a t-rex, but also not intimidating, just looks like a toy or cartoon character.
Dragons generally have to be edgy to be super popular; but also not *just* dragons, but something removed from dragons too; but also inherently powerful.
