Enderdragon

Ender Dragons are giant monsters that live in the End. They gain power from the Ender Crystal Towers and occasionally shoot Ender Acid at enemies. In SuperMarioGlitchy4 bloopers, the Chinese Dudes refer to the Dragon as a "Demon of the Underworld", and the End as "Underworld". Ender Dragons is the first boss mob to be introduced in Minecraft, next is the Wither Boss.

Appearances
Ender Dragons appear only in the blooper Befriend the End, where Smg4, Mario, and Starman3 find the magic orb dropped by the Chinese Dudes and accidently travel to the End. They meet Endermen and other creatures, but they find out they need to escape when the Ender Dragon chases them. They get help from a old hobo and try to use the orb to get back, but the Ender Dragon knocks it to the Void. Then it calls many other relative Ender Dragons to attack them. Luckily the Chinese Dudes arrive and freeze time to have the trio escape, but Mario, being a fool, presses the orb again and they travel back to the End... with the 1000000 Ender Dragons stalking them.

Trivia
The Chinese Dudes refer the Ender Dragon as a demon.

The Ender Dragon's only quote is "PINGAS!!!"

Ender Dragons cooperate with Endermen.
