The most forgotten Dragon is Hakamo-o. I never see anyone discussing its presence at large. It is also relatively new. Vibrava has the novelty of evolving into a popular Pokémon, and the single stage version exclusive Drampa has an exclusive type combination and a role in the anime. Hakamo-o is forgotten.
>>48386589Druddigon is meant to be the common Dragon Pokémon in Gen V and in future gens, being the first one that does not have an evolutionary line and isn’t Kegendary/Mythical, and still being the only one that is pure Dragon. Druddigon is available relatively easily in every generation since it debuted, albeit it is only available in USUM and Isle of Armor/Crown Tundra.
Druddigon has also been on the teams of Iris, Drayden, and Drasna.
>>48386560Haxorus was one of the first Dragons to debut during Gen V and is Iris/Drayden’s signature Pokémon. It is also the fully evolved form of Iris’s signature Pokémon in the anime, and it eventually becomes that signature Pokémon when she returned in PM2019.
