You know, i've always thought that we humans are a very unfair specie... we don't have predators that eat us! To be fair with mother nature and give a little bit of chance to the dragons family, I think I'm with the human slayer for now, hehehe
Sorry for taking this off-topic, but we do have one species that is a predator.
Sure lions, sharks, crocodiles and even driver ants will attack humans for food if they are hungry (opportunist hunting), but only one animal will actively predate on humans.
The polar bear.
