With just D&D dragons, I played up their intelligence, age and nature as predators used to operating in 3 dimensions. The nastiest ones were spellcasters, but more like sorcerers than wizards: knowing a few spells that they spam.
Some stood out:
1) A blue who was partnered with a martial spellcaster who rode him. They attacked the party’s airship while they were in the clouds…from below. The dragon clung to the ship’s underside while it darted its head over the front to bite or breathe, and it’s tail over the back to sweep the deck. The ship shielded most of its body. It’s parner boarded the ship to provide additional support. When the battle turned against it, it simply released its gip and disappeared back into the clouds.
2) The party was approaching what they had been told was the dragon’s lair. Then they saw it approaching,then diving for a strafing run. Being a high-level snd hubristic bunch, they prepped themselves for combat in situ rather than scrambling off to the roadsides. As a result, they were prepared for the dragon to breathe on them from the front. They were NOT prepared for that attack to be an illusion cast by the dragon- he dropped a few claws-full of boulders on them as he passed over them from their rear.
3) Another, cornered in his lair, shoved a big pile of his trove at the party, limiting their mobility and even knocking some down. Then he slagged some of the treasure they were standing in…
