[General Fiction] Are dragons warm blooded?

Especially the fire breathing kind. Or do they sometimes still need to leave their caves.

Depends on the Dragons. 

D&D dragons sort of are, though it's not thermal energy they, but Elemental. A White Dragons blood is ice cold, but that's because of the Dragons elemental nature, and it doesn't interfere with its metabolic functions at all. In fact, cold POWERS them.

In TES, they could sort of be considered Warm Blooded, though I'd hardly consider them blooded at all, being physical manifestations of moments...

In Warhammer, Dragons are cold blooded, though certain varieties react differently to heat than others. The greatest of the Dragons find too much heat lethargic, and have been mostly sleeping since the Old Ones moved the planet. Presumably they could more be considered gigantothermic... Smaller varieties, like those generally seen by mortals, are very much cold blooded, but too large to effectively Sun themselves, and congregate in volcanic areas to bask in the warmth of thermal vents.

In Might and Magic, no, Dragons are not cold blooded. The same can be said for Age of Wonder and Desciples. And Warcraft.
