(Though The Bible says Leviathan is the dragon, ancient (serpent)snake, the beast,satan, And in the war in Heaven Mikael defeated the beast/Satan.

Though also described as the beasts that some think are the dinosaurs. T-rex etc. and that they could make fire with their breath,aka dragon.

Behemot is another creature, that is called Gods greatest creation on earth, but is a vegetarian.) big tale and the mountains carry its food.

It seems like Supernatural is following some of the Bible's story in basic, but has alot of other stuff in the mix too.

But according to the bible, Satan comes as antichrist, then after that as the beast.
