Ender Dragon

The ender dragon is a giant flying hostile boss mob found when first entering the End. It is the largest naturally spawning mob in the game. It guards access to the end gateways that provide entry to the outer end islands in addition to the exit portal that allows return to the Overworld as well as access to the end credits of Minecraft. Because of this, it is known by most Minecraft fans as the 'final boss' of the game. Its attacks involve charging at the player and its unique dragon acid attacks.

Players can re-summon the dragon by placing four end crystals on the edges of the exit portal, one on each side. When it is re-summoned, the four end crystals point to the tops of each pillar setting off a series of explosions that resets the obsidian pillars, iron bars, and end crystals. The top of each pillar explodes, destroying any player-placed blocks. Eventually, all of the end crystals point at the coordinates of (0.0, 128, 0.0) and the ender dragon spawns there. The four crystals placed around the exit portal then explode. If the player does not pick up the dragon egg and starts to re-summon the dragon, the dragon egg disappears.

If the dragon goes through an end gateway, another immediately spawns at (0, 128, 0) while the other dragon flies to (0, 128, 0).
