Since dragons are starting to rely on puns and nods for a little more diversity, let's play a game.

Come up with a possible inspiration for a Pokemon and justify why it is possible for said inspiration to result in being a Dragon Type. Do note that said inspiration cannot be blatantly a dragon and must be subtle.

Hard mode: no seahorses.

>An actual vampire Pokemon
Because Count Dracula, with Dracula meaning 'son of dragon' and stuff. This Pokemon is not dragonoid in appearance and seems more akin to the likes of humanoid Pokemon such as Gardevoir. Perhaps the pre-evolved form could be a bat? Oh wait, Noivern already did dragon bats!

>Regional Cat
One of many tales in Norse legends has Jormungandr transform into a great cat to be lifted by Thor. The only Pokemon that can learn Assist and Coil throughout its evolutionary line.
