>>33457799>SalamenceThose things are noted to have dreamt of flying since they were Bagon. As far as I know, those kinds of aspirations are unusual in most animals.
Also they only evolve because they want to fly so damn badly it changes their cellular structure, which is all kinds of amazing.
>HaxorusDescribed as "kind" when not defending territory, which (to me, at least) suggests some level of intelligence. As Fraxure, they're also smart enough to know that they have to sharpen their tusks after every battle so they don't break.
>KingdraI always thought that these were pretty smart. Pokedex says fuck all about how smart they are, only that they're powerful enough to cause massive whirlpools just by yawning. Then again, they're fish first and dragons second.
You also left out amazingly friendly Dragons like Altaria, Goodra, and Drampa.
