ender dragon
The ostensible "final boss" of Minecraft and the largest single mob in the game. The Ender Dragon is a giant black dragon that appears solely in The End, where it flies through the sky and swoops down to attack the player. To kill it, the player must first destroy a series of end crystals atop obsidian spires, which the Ender Dragon will use to heal any damage it sustains.
On her first death, she will drop a dragon egg.
