I searched under the "Characters as [Plot] Device" for a suitable trope for PlatedDrake.
How about Dragon Rider?
Let's face it: you can't get much more Badass than a Dragon. They're huge. They fly. They breathe fire. They have weapons sticking out of nearly every part of their body. They're really, really smart. They're brutal and merciless in battle. They live for thousands of years, they wield magic, and their tough scales make them both pretty and Immune To Bullets. (Well, it really depends.) As the most well-known and widely overused mythological beast, dragons have always served as the quintessential boss monster in games, books, and myths, representing the ultimate incarnation of power and evil which endangers all life on earth.
Until now! [I wonder if until now! is itself a trope, implying change from the present state of affairs.]
Somewhere along the line, somebody got the bright idea that maybe these vicious, bloodthirsty beasts don't have to be so evil after all. Maybe underneath all those fangs and claws, they're just gentle, misunderstood creatures who might just be willing to fight on the side of the good guys if you're lucky. In fact, maybe they're just looking for a friend.
And thenceforth, there came the idea of a Dragon Rider, a human (or humanoid) who is so mightily goddamn badass he can actually ride on the back of these beasts, often as a steed into battle. The concept exploded and gained ridiculous popularity among fantasy authors, and now can be seen... well, just about everywhere in modern fantasy literature.
Dragon riders are almost always characterized by a bond with the beast they ride which results in a synchronous relationship between the two, a telepathic link, and no possibility that the two could ever be separated from each other without drastic consequences. They'd better get used to each other's company- they're stuck.
Dragon rider characters fall into the trap of being Mary Sue characters all too often, simply because the whole idea doesn't make all that much sense. In some cases, the human might fill some gap in the dragon's own abilities - an old-fashioned, unintelligent dragon might need a rider for direction, and a non-firebreather might benefit from having a wizard on its back - but most dragons are so all-around awesome that the human is redundant. And of course, that legendary magic sword of yours isn't going to do much good up there either—unless you plan on, I dunno, dropping it on the Big Bad?
But this trope will keep coming back, because of wish fulfillment. Dragons are cool. A dragon you can fly around on is cooler.
May sometimes be called wyverns, a different dragon-like mythical creature.

Very well then, what trope or tropes would you think of for a guy like me?
