Mob (entity)

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

Spawning
Human mobs would generate in random places when a world was generated at Pre-classic. Later, they could be manually spawned by pressing while playing in Classic mode. After both of these features were removed, they were only spawnable using mods and map editors, but otherwise were not available in vanilla Minecraft.

Drops
Humans do not drop anything when they die.

Behavior
Humans could not change 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 the default skin and would not assume the look of the player.

Attacking the player
When humans were first added, they would just hop around the map when spawned, but in later versions, they would hurt 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.

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 Java Edition 1.8 (under the generic name "Monster"). Only the human model was removed in Beta 1.8.
 * It is unknown if humans exist in the Xbox 360 Edition (in versions when Java Edition was pre-Beta 1.8). It may be true if the player 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.
 * Their are the first mob added to Minecraft.
