Enderman

"This long-limbed, purple-eyed, darker-than-night mob is not one you want to get into a staring contest with. Usually seen in the Nether and The End, its presence is rare in the Overworld. Rarer still - players who've made eye contact with it and then survived to tell the tale. Though I have."

- Tom Stone

Endermen are tall, black and have the ability to teleport, and pick up blocks.

Attack- Endermen are usually neutral if left alone but charge if you look them in the eye. They start to shake and make a growling noise until they run at you with an open mouth. It's very tricky to kill them as they normally try to teleport behind you and take you by surprise! Interestingly, if you put on a pumpkin head they won't attack you. Weird but true! If you find a clever enderman it might even accidentally create a snow golem or iron golem. Don't try and shoot them because they will teleport away before the arrow hits them. You'll be quite safe though if it's raining or your near a source of water since it damages them. I sometimes enjoy watching Endermen running around screaming (or rather teleporting around) in the rain, it's a funny thing to watch if you have a grudge against one!

Spawning
An enderman can spawn at light level 7 or less, on any solid surface having at least three empty spaces above. They spawn in all dimensions.

Overworld
Endermen spawn uncommonly on land and in caves in up to packs of two.

Nether
Single enderman spawn uncommonly in nether wastes and soul sand valleys, and frequently in warped forests.

End
Endermen spawn commonly in packs of up to four in the end islands.

Drops
Endermen drop:


 * 0–1 . The maximum is increased by 1 per level of Looting, for a maximum of 0-4 with Looting III.
 * when killed by a player or a tamed wolf.
 * Any block being held (see for more information)

Behavior
"This mob becomes hostile if you attack it (easily avoided) or if you just gaze upon it (oh dear). Considering it can run at you, teleport around the world, and chase you with obsessive persistence just because you looked at it the wrong way, we'll give you some friendly advice: don't get caught staring. You should get that tattooed on the inside of your eyelids to help you remember. Thank us later."

Endermen do not attack unless provoked by a player or mob attacking them or a player looking them in the eyes from up to 64 blocks away. When provoked, endermen open their mouths, begin to shake aggressively, and make frequent screaming sounds. When provoked by being stared at, they also make a lengthy, loud, threatening sound. If the player maintains eye contact, the enderman does not run, although it may teleport away. Once the player stops looking at the enderman, it runs toward the player to attack. If an aggravated enderman is hit by another player or mob, it ceases to attack its original victim. Endermen even try to retaliate against the ender dragon if the dragon deals damage to them, but fail to do any damage as the ender dragon pushes them away. An aggravated enderman may also teleport to the location of a player or mob up to 4 chunks away.

Enderman can also step up one full block without having to jump.

Endermen are damaged by melee attacks, water, splash water bottles, and rain, and may teleport away when they take damage from any of these ( every half second for water and rain, and for splash water bottles). They repeatedly teleport until they find a dry location. However, endermen do not take damage while standing in a filled cauldron. They also teleport if they take damage from other sources such as suffocation, fire, lava, poison, or the wither effect. Ranged attacks are ineffective against endermen because they simply teleport away before the projectile hits.

Endermen pursue the player until they are either killed or become distracted by exterior elements like rain, fire, or sunlight (they do not take damage from sunlight like undead mobs). During times like rain or daybreak, they are likely to teleport away to underground locations, such as caves. An enderman (whether neutral or aggravated) in a player's vicinity prevents the player from sleeping in a bed at night as if any hostile mob were nearby. If the player is already asleep in a bed, it is possible for an enderman to teleport on it and knock the player off, although the player continues sleeping.

Endermen cannot be provoked by players looking at them through transparent blocks. Endermen also cannot be provoked by players looking at them while wearing a carved pumpkin on their head or by players under the invisibility effect. Endermen cannot normally be provoked while the player is in a boat, however, they can become aggravated by a player in a minecart from some angles. Attacking an enderman provokes it even if a carved pumpkin is worn. However, Endermen don't usually get angry at the player if the player looks at the ground or at the Endermen's feet while approaching it.

Endermen attempt to kill endermites that spawned from the use of ender pearls. Endermen do not attack endermites spawned through any other means such as spawn eggs. Endermen can spot endermites from a distance of 64 blocks.

When an enderman is under the Invisibility effect, the enderman's eyes are still visible $$.

Teleportation
When teleporting, for each attempt a random destination is chosen within 32 blocks along each axis (i.e. a 64×64×64 cuboid centered on the current position). It then seeks downward, regardless of distance, from the chosen destination until the block below is made of a movement-blocking material. The teleportation attempt succeeds if no liquid or solid blocks prevent them from standing at the destination. Thus endermen need at least three non-solid blocks above the destination to successfully teleport. Endermen never teleport into waterlogged blocks. Exceptions are carpet that is not above a block made of a movement-blocking material, lily pads and snow layers stacked 10 deep or more, as their materials are not flagged as blocking movement even though the blocks themselves do so.

Endermen always attempt to teleport upon taking damage, such as from water. Most ordinary melee attacks are successful but are usually followed by an immediate teleport to a few blocks behind the attacking player. Endermen cannot normally be attacked with projectiles $$ (including splash potions of harming), as they always teleport away just before being hit, unless they are in a boat or minecart. However, they do not teleport if positive potions are thrown at them, including splash potions of regeneration and strength, and do not teleport away from poison potions either. A splash water bottle deals damage to an enderman if it is caught in its radius of effect. If all available blocks within teleport distance are removed or unable to be transported to, it is possible to hit endermen $$ with a projectile, though arrows may bounce off dealing no damage on occasion. When teleporting due to damage, an enderman can make up to 64 attempts to teleport.

If it is raining and there are no caves nearby, or on Superflat worlds, endermen frantically teleport over the map, taking damage until the rain stops, they find cover, or they die.

An enderman cannot teleport while it is in a minecart or boat, although in rain and water it attempts to do so, always teleporting back repeatedly until death. This does not occur $$.

Endermen do not teleport in the daytime while on soul sand unless they are damaged. They also do not teleport if attacked on their legs or by wolves, as wolves attack at the legs. Endermen also hardly teleport when combating other mobs like iron golems.

They play a sound exclusively at the teleportation destination.

Moving blocks
Endermen have a unique ability to pick up, carry, and set down certain block types. They silently pick up blocks in a 4×4×3 region horizontally centered on the enderman and vertically at the same level as the enderman itself. One side effect of this is that an enderman cannot pick up blocks in a completely flat area. Endermen drop the block they are holding upon death as an item, though they do not visually let go of the block when dying. Unlike other monsters that picked up items, endermen that picked up blocks can despawn pre-20w21a (Java Edition).

Endermen can pick up the following blocks:


 * Fungi
 * Roots
 * Crimson and Warped Nylium
 * Fungi
 * Roots
 * Crimson and Warped Nylium
 * Roots
 * Crimson and Warped Nylium
 * Crimson and Warped Nylium
 * Crimson and Warped Nylium
 * Crimson and Warped Nylium
 * Crimson and Warped Nylium
 * Crimson and Warped Nylium
 * Crimson and Warped Nylium

Data packs can change this list by modifying the  block tag.

When carrying a block, the enderman may randomly silently place it, in a 2×2×2 region horizontally centered on the enderman and vertically at the same level as the enderman itself, if the target location is air with a non-air block beneath and the block is allowed to be placed at the target location.

While endermen may breach walls, bridge fences, break redstone circuitry and even construct golems by removing or placing blocks, they can also potentially set off explosions and kill themselves if they place a block of TNT on a power source. However, none of these actions are ever intentional and are completely random if they occur.

One can summon an enderman holding any block (including the ones not listed above) using the  NBT data.

For example, to summon an enderman holding with no AI where players are standing:

/summon minecraft:enderman ~ ~ ~ {NoAI:1,carriedBlockState:{Name:"netherrack"}}

Data values
Endermen have entity data associated with them that contain various properties of the mob.

Trivia

 * The sounds endermen make are actually people saying "Hi" and "What's Up", but backward and distorted.
 * Notch claimed in public that the enderman is a "subtle reference to "the Slenderman", a similar-looking monster with a similar name. Given the later development of the End, it is possible he already had the name in mind, and did not choose it because of the Reddit thread in which their name was revealed. In the Halloween texture pack for Legacy Console Edition, the enderman is re-skinned to look like Slenderman.
 * The collective noun for a group of endermen is "a haunting of endermen", as stated by Dinnerbone. Additionally, in the third episode of Minecraft: Story Mode, The Last Place You Look, a player is given the option to correct the grammar of other characters by specifying that the collective noun for a group of endermen is "a haunting of endermen."
 * Switching to spectator mode and taking an enderman's point of view adds a shader that inverts colors, suggesting that they see the End as an island of blue cobblestone (because end stone is a yellowish version of cobblestone with inverted colors) in a white sky, with white pillars, white endermen with green eyes and a white ender dragon, also with green eyes. They also see cobblestone as end stone.
 * The texture for an enderman's eyes is located in a different texture file than the body, allowing their eyes to glow. Because the two textures do not line up perfectly, forcing an enderman to look straight up causes its eyes to turn blank white.
 * The enderman teleportation sound also plays when a player teleports using an ender pearl or chorus fruit.
 * Endermen are the only mobs who naturally spawn in all three dimensions.
