Oro does, Barioth is quick as hell, I can often not even dodge his pounces. Not to mention he can fly. Why can everything fly in that game? Even Diablos, a giant loving rock monster has wings.
Because everything is a wyvern. Even the Great Jaggi. The only reason it can't fly is because it's yet to develop wings, it's a dinosaur, and birds evolved from dinosaurs (This is most evident in the Qurupeco, what with it's feathers). Technically, even the Ceadeus and Jhen Mohran are (elder, as they say in Minegarde) dragons, though the only really straight forward dragon is Alatreon, and he's technically a mash-up of all of the other final boss Elder Dragons.
