Dragons

“	Bofur: Airborne fire breather, teeth like razors, claws like meat hooks, extremely fond of precious metals - Bilbo: Yes, I know what a dragon is.	„
	~ Bofur describing Smaug to Bilbo Baggins.

“	This man slayed countless Dragons and soaked in their blood. He used his Powers so often that his skin turned to scales, his teeth... Sharpened into fangs... And he stopped being Human altogether.	„
	~ Zirconis explaining Acnologia's Transformation.

Dragons are one of the most powerful (and popular) creatures in the worlds of mythology and folklore. In many works of fiction Dragons are mostly portrayed as antagonistic forces, some being savage beasts while others are reasonably intelligent and even able to communicate with other lifeforms, namely humans. Some Villains can also turn themselves into dragons using magic or similar powers.

The physical appearances of Dragons in fiction (either villainous or heroic) are not always the same between one another. Broadly speaking, Dragons can be divided into the following groups depending on the traits they possess:

Western Dragons are depicted as fire-breathing and horned lizard-like creatures with leathery bat-like wings, four legs and a long tail. They are sometimes shown with feathered wings, crests, fiery manes, ivory spikes running covering their bodies and exotic colorations. A Dragon's blood and armored scales often have magical properties. The typical Western Dragon protects a cavern or castle filled with treasures and is often associated with a great Hero who tries to slay it. Though winged and capable of flight, the Dragon is generally to be found in its underground lair that identifies it as an ancient creature of the earth.
Asian Dragons are portrayed as serpentine creatures with four legs. Traditionally they symbolize potent and auspicious powers, particularly control over the elements and are representative of strength and good luck. They have also an extended range of supernatural powers such as changing their size and form (mostly to take on human shapes) or color (to blend in with their surroundings as a form of camouflage).
Lesser Drakes are something of a catchall category including Lesser Draconian Beings such as Wyverns, Wyrms, Lindworms, etc. which are generally smaller and more feral in mind and behavior. Though not entirely accurate to being called Dragons, Lesser Drakes are often considered the distant kin of most Dragons. These also include Wyverns commonly depicted as a subtype of Dragon lacking forelegs due to their wings and modified front legs.
