Using actual biology, not videogames...

I used a movie for reference, actually. There is no officially established physiology or biology for dragons, but I do remember a report from Discovery speaking of many residuals of 'charred' matter found on some 'supposed' dragon fossils in their lungs. As weak as that argument sounds, it gives enough base to consider the legitimacy of believing a dragon's physiology could very well differ from your traditional oviparus reptilian. And like I said, it carries over when they are anthropomorphized, so it all depends on their base physiology- It is, however, a completely subjetivist topic, and with that, I repeat that there is no officially established records of any sort of charted biology for dragons.
