Mob (entity)

Humans, known as monsters in the code, were hostile mobs with the default skin.

Spawning
Humans could used to be manually spawned by pressing while playing in Classic mode, but this function was later removed. After this was removed, they were only spawnable using mods and map editors, but otherwise were not available in vanilla Minecraft.

Behavior
When humans were first added, they would just hop around the map when spawned, but in later versions, they would pursue and kill the player, dealing the same damage to the player as the player does with their fist. Strangely, they did not use the punching animation that a normal player would use; they would only run into the player like a zombie would.

Humans could not create or delete blocks; they would just move around the map aimlessly, walking in slightly imperfect circles and jumping occasionally. While walking, they would flail their arms around and move their head randomly. Humans were affected by solid blocks, but they were able to walk right through liquids, as if they were air. If the player had a custom skin, any humans created would still use default skin and will not assume the look of the player.

Trivia

 * Humans, when spawned, may head to the left for half a second, before turning around to attack the player. Zombie Pigmen may also do this on occasion.
 * If a human spawner is placed in Beta 1.8 or later, it will be blank and no mob will spawn.
 * Coding for humans was still present until 1.8 (under the generic name “Monster"). What was actually removed in Beta 1.8 was the model.
 * It is unknown if humans exist in the Xbox Edition (in versions when PC was pre-Beta 1.8). It may be true if you changed the version to a pre-Beta 1.8 equivalent, and you tweak the mob spawner to "Monster" via mods.
 * Humans use the old Player model, so they are actually taller than the player.
 * Humans sometimes found it difficult to retaliate against other mobs that hit them.
 * Despite being taller than the player, humans looked up at the player when chasing them. This is because their actual hit-box and eye height were shorter than the player's hit-box and eye height. The same is true for all bipedal mobs.
