The definition of Dragons:-
A mythical beast usually represented as a huge, winged, fire-breathing reptile that is often warm-blooded.

For centuries the dragon has been prominent in the folklore of many peoples; thus, its physical characteristics vary greatly and include combinations of numerous animals. The dragon has often been associated with evil. In many legends a dragon had the ability to wreak havoc upon a land and therefore had to be either propitiated by a human sacrifice, or killed; it was also often the guardian of a treasure or a maiden. The highest achievement of a hero in medieval legend was the slaying of a dragon, as in the story of St. George. King Arthur, son of Uther Pendragon (dragon's head), also killed a dragon. The giant red dragon of the Apocalypse gave rise to the use of the beast as symbolic of Satan in Christian art and literature. In ancient China the dragon was associated with fertility and prosperity. Many of the beliefs connected with the dragon are echoed in snake worship.

Dragons deserve a category all their own because they are beasts found all over the world. But there are two distinct types of dragon: the dragon of the Western world and the dragon of the Eastern world.

Western Dragons

Native Americans believed in snake dragons, supernatural wisdom.

These enormous, fire-breathing serpents have scaly green bodies and huge red wings. Greedy creatures, they hoard gold treasure in dens under the earth. Fierce and always hungry, a Western dragon will eat anything but especially likes weak, young, human flesh. Dragons live in caves, mountains, or lakes. They were particularly active in the Middle Ages, when brave knights challenged them to battle.

Eastern Dragons Compared to Western dragons, these beasts are quite small. Their bodies are long, and they have two horns for ears. They have no wings, and their soft breath is said to form clouds. They do not roar; instead they make the sounds of beating gongs and jingling bells. Chinese dragons dine on sparrows. They live wherever there is water. They are kind and wise friends of human beings.

The western and eastern dragons are some of the most referred to of the dragon species. Many trans-breed dragons have derived from these two types. In a few instances, some Dragons will take livestock from nearby farms. Many times the missing will be sheep.
