Dragons are mean, Jennifer. They eat people. They breathe fire so they can burn and eat people. Not that I'm going to judge, hell I've done worse but that's just how it is.
If you want to know what they're like... well, they're ugly and scaly and they smell and when they die they make the most hilarious screeching noise! Not all of them have red blood, either! Some have purple... green... all kinds of colors.
