Ender Dragon

The Ender Dragon is an extradimensional being that inhabits the End. It's the final boss of Minecraft, although after defeating him you can still continue the game. After death it drops a unique item called "Dragon Egg" and a lot of experience points. It is unknown how old Ender Dragon is and if there are any other members of his species. Many players believe that this is the last Dragon in the Minecraft universe.

Behaviour
Unlike the humanoid Enderman that will only attack if attacked or stared at, the Dragon is agressive and will attack players or anything that attacks it. Ender Dragon is also extremely territorial creature and treates whole The End dimension as its property.

Abilities
Except its natural ability of flying, Ender Dragon can also regenerate itself by using Ender Crystals placed on high pillars made entirely of obsidian.
