I dunno, how many Japanese businessmen and -women can you jam into a bullet train zooming past Mt. Fuji?

Enclave, I just ... the fact that you are
asking the question sort of baffles me, I confess. And without even touching on wealth (immense), mystic power (likewise), or physical capabilities (impressive), I'd just like to note one thing: Dragons, particularly the Great Dragon sorts that you're speaking of, have IQs of roughly
400. Incredibly smart human? 180 to 210, read as 6 or 7 Logic. Ever see the movie 'Limitless'? I would guess that that guy approaches 300. Now step it up not just one notch, but
three.
Next, look at
our reaction to them. These are beings of great mythological stature. I posted (several times) to a question regarding them in the HERO Games forums; the
first reply possibly serves you best. The thing of it is, though, is that a dragon is the entire meaning and symbol of How The World Changed. Screw cyberware, screw VITAS, screw the Matrix and magic;
Here There Be Dragons. The Brits weren't about to send the army after Rhonabwy, since he'd just shown that hey, just having a post-nap epileptic seizure he can bloody
wreck a town. Now that he's awake, what would he do to an armored division?
Well, for more on that topic, we turn to our KSAF reporter in the skies over Denver on 25 December 2061... (See Year of the Comet, p. 59). This is 'inherent abilities'; see also Tehran and Brazil.
For more on resources, we turn to The Dragon With The Most, your pal and mine, Goldfing... errr, Lofwyr. See, he not only has the inherent abilities, he also has the world's largest corporation -- and the economic, political, and military might (which includes both satellite weaponry and a nuclear stockpile) that it possesses.
I'm not trying facetious, I get that they do have this power so they got it in some manner; maybe it's just because they don't really interest me that I question them?
If you are playing the same game we are, and your GM is paying attention, dragons should interest you if only in a player's self-defense. Humanity are a bunch of 4-year-olds with Nerf bats; dragons are a 35-year-old athletic adult with a gun collection and a heavy pickup truck. Usually the 35-year-old drives carefully around the 4-year-olds, keeps his guns in a safe place, but if the 4-year-olds tried to take him on, well, it's gonna take a LOT of 4-year-olds with Nerf bats to get him down.
I think we're just wondering how, exactly, do you mean to be 'questioning' them. If playing AD&D, reading the Hobbit, anything fantastical with a dragon in it doesn't make you think about what happens when you give a dragon lots of years to collect treasure, give him an IQ the height of the Renraku Arcology (ACHE to you 4edders out there), then turn him loose in a world where 'dog eat dog' is only barely not a literalism in the economic sphere, then you need to face down a few more dragons in the non-4e AD&D universe...
