Can confirm, I run a LOT of dragons and the interesting dragon villains are generally about finding unique takes on their common traits or villains because of their response to their circumstances rather than pure random villainy. We've got the red dragon who self-perpetuates her own cycle of violence, we've got the black dragon who's mentally broken because their worldview of being entitled to everything due to their strength collapsed after they lost a territorial struggle, we've got the emerald dragon who's desire not to be bothered by their humanoid allies led them to neglect their promises, we've got the silver dragon who loved her friends so much she was willing to fall into necromancy to try and undo their deaths.
Also we have That Bastard With Eight Player Kills.
That said, always remember: To become cliche, something needs to work super well first- so well that everyone does it. It only crosses from great into cliche if everyone does it and forgets why and how it worked in the first place.
