Enderman

Endermen are tall black creatures that come from the end. They will teleport away from you if you come close to them, and will teleport closer to you if you hurt them or looked at them directly. They are only available on Desktop and XBOX 360 versions.

Appearance
They have black skin and very long arms. They are sometimes seen holding blocks. If provoked, they will open their mouth. They are one of the six mobs that can open their mouths. The other five are the Enderdragon, the Ghast, the upcoming Horse, the upcoming Donkey, and the upcoming zombie or skeletal horse.

Attack and Type
The Enderman attacks you by teleporting closer to you than hitting you with both arms. They are neutral, which means that they won't attack until provoked or looked at.
