enderman
A neutral mob in Minecraft, native to The End while being able to spawn in all three dimensions. Endermen are tall black humanoids with elongated limbs, and purple eyes. Noted for their ability to pick up and move certain blocks such as dirt and flowers, disrupting a player's constructions.
While being stared, Endermen will freeze in place and begin shaking before teleporting to attack the player. They will then teleport to the player and attack once the player looks away. They have been compared to a Weeping Angel in this respect, though they do not remain motionless when in visual range.
