The ender dragon is a gigantic flying hostile boss mob found when first entering the End. She is the largest naturally spawning mob in the game. She 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.
Initial spawning
The ender dragon spawns 20 ticks after an entity first arrives in the End, along with the bedrock frame for the exit portal.
Re-summoning
This image shows how the player can arrange end crystals to respawn the ender dragon.
Players can re-summon the ender dragon by placing four end crystals on the edges of the exit portal, one on each side. When the dragon 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 corner of (0, 128, 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 a dragon goes through an end gateway, another immediately spawns at (0, 128, 0) while the other dragon flies to (0, 128, 0).
Drops
After the ender dragon is slain for the first time, the following events take place:
She slowly ascends, her wings and body becoming more tattered until she disappears in beams of light erupting from her center.
There's an explosion of 12,000 experience points (ten drops of 960 and one drop of 2400) — enough to bring a player from level 0 to level 68. If killed on top of the bedrock structure, some of the experience orbs will drop into the exit portal. The experience orbs can then be retrieved in the overworld.
The bedrock structure fills in with an end portal interface to become the exit portal, enabling the player to transport back to the Overworld and respawn at their spawn point.
A dragon egg appears above the island's central bedrock structure. If a block exists right above the center of the central bedrock structure, then the dragon egg spawns 1 block above the highest block at (0,0). If the highest block is at the height limit, then the dragon egg does not spawn.
An end gateway portal is generated floating within 75–100 blocks of the exit portal.
When a re-summoned ender dragon is slain, the same events occur except that only 500 experience points are dropped [Java Edition only] and no more than 20 gateway portals are generated. The dragon egg appears the first time the ender dragon is slain in Java Edition, and the first and second time in Bedrock Edition; it does not appear after any subsequent dragon slaying.
Trivia[]
The Ender Dragon could formerly be damaged from Snow Golems, snowballs, eggs, and fishing rods but it will not anymore after 1.9.
On console edition, at the two tallest Obsidian pillars, they spawn Iron Bars too. Iron bars are gonna be spawned in PC, in 1.9.
Notch (aka Transphobe bitch) was confirmed the Ender Dragon is a female and her name is Jean.
Notch hates red, I mean I know he hated pink and yellow too but this is too far
Notch (also known as Fuckhead for a unknown reason) also originally planned to add a Red Dragon that would spawn in caves for the player to tame and help fight the Ender Dragon
