Enderman

An enderman is a neutral mob found in all three dimensions that has a chance of dropping ender pearls when it is killed. It becomes hostile to players that damage it or look directly at its face, using its arms to attack. Endermen teleport erratically, as well as away from dangers such as lava, projectiles, and water. They also occasionally pick up and move certain blocks.

Endermen can spawn on any solid surface that has at least three empty spaces above, at a light level of 0 in the Overworld and the End, or a light level of 7 or less in the Nether. They are the only mobs that spawn naturally in all three dimensions in Java Edition.[2]

Endermen spawn uncommonly in all Overworld biomes except mushroom fields and deep dark. In Bedrock Edition, endermen also do not spawn in rivers, frozen rivers, and snowy plains. They spawn in groups of up to four in Java Edition or up to two in Bedrock Edition.
