A dragon

Dragons were magnificent ancient creatures. Dragon is a dangerous race of monster with wings and the ability to use a fiery attack. Dragons are feared by others as they were admired on Earth. They were immortal, powerful and intelligent. Their origin is unknown, but they may have been bred by Daedalus's Chaos Gods during the forming of the Eye of Terror, the giant warp storm above Mars. Because the first dragon ever seen on Earth was a Greater Dragon whose name is unknown, it worked for the dark powers of Daedalus. However, they also known to breed on their own without a dark lord. Many of the dragons didn't look like monsters like the evil orcs, ghouls, and werewolves. In fact, some men honored dragons for their power, as well as fearing them and have engraved dragons onto their shields and banners as tribute. 

Dragon racesEdit

The Ender Dragon is a large, black dragon with glowing purple eyes. It has a few dark gray features, such as the wings and various other parts of its body. Enderdragons have the ability to take the form of Humans. This was discovered during the Purge of Asmihlya when an enderdragon took the form of the Daemon Prince, Anathema VII.

Similar to Endermen and Spiders, the Ender Dragon's eyes are visible through darkness, so you can see it coming from anywhere in the End.
