Iron Golems look similar to their villager counterpart. They have tall heads, uni-brows, and large noses. They have black eyes with red pupils. They stand nearly as tall as an Enderman. They seem to be covered with vines and plants to reference ruins of fallen ancient civilizations. They also have perfectly straight arms that they never bend as well as large shoulders. They also have thick legs. Whenever they get hurt you hear an iron pounding sound; however, other than that they don't make any other noises.
The golems can be crafted using blocks in a similar fashion to Snow Golems. To do so, the player must vertically place 4 Blocks of Iron in a T-shape, and place a Pumpkin or a Jack-o-Lantern on top. The pumpkin must be placed last. They will always spawn facing south. Iron Golems cannot be manufactured by a Piston assembly line without player(s) interaction. Players should not manufacture iron golems next to a wall because it may take suffocation damage and die.
Iron Golem build configuration. Players should take note that Iron Golems, like Snow Golems, cannot be crafted in a crafting table. As of update TU12, you can only make 16. The 17th one will explode into a pumpkin and 4 iron blocks.
Iron Golems behave similarly to a tamed Wolf, although they are slower and loyal to Villagers instead of players. Iron Golems are also a lot more powerful in that they have a greater attack force, a greater attack radius, more health, and are completely resistant to drowning and fall damage; making them good tools for both villager protection and personal use. Note that they do not regenerate HP but can be healed with a splash health potion. Like villagers they will not wander away from the village, regardless of whether they were spawned naturally, or created by the player. Hence building them in a village is a good idea to keep them from wandering away. However if they were built outside of a village, they will most likely wander away if there is no barrier. Iron Golems will act normally around villagers, and sometimes will face a villager, as if they are speaking to each other.
Iron Golems are able to hold roses and give them to Villagers, symbolizing the friendly relationship between the Villagers and Iron Golems. However, they won't give roses to other iron golems, regardless if they were created by the player or spawned in a village.
Naturally spawned Iron Golems will attempt to attack the player if the player attacks them first, but will quickly give up (sometimes so quickly it will appear the golem didn't try to attack the player at all). However, if the player attacks nearby Villagers enough, iron golems will pursue the player (only in Survival Mode). The Iron Golem does not have to directly see the player attacking a Villager to become hostile toward the player. If an Iron Golem is provoked by the player attacking it or a Villager, the golem will become neutral again after the player runs far enough away. Any Iron Golems generated through other means will not defend Villagers and have a habit of wandering off. Iron Golems will not attack Ghasts and will only attack a Creeper if it has a low amount of health. On rare occasions, a creeper might explode, killing the iron golem that is attacking it.
Iron Golems will only attack hostile mobs within five blocks on equal ground. During village sieges, however, a naturally spawned Iron Golem will seek out any hostile mob threatening a Villager, regardless of distance . When provoked, Iron Golems will move quickly toward their target and once in range will swing their arms up violently to attack, dealing 3½ to 10½ hearts damage and flinging the target into the air. This attack is the strongest melee attack in the game, and one of the strongest attacks overall, only being beaten by a Creeper's explosion. Iron Golems have a comparatively large attack range, allowing them to attack through a solid 1 block thick wall, even without line of sight to the target. Please note that Iron Golems also attack zombie pigmen, making them a vulnerable target for hordes of zombie pigmen, wolves (tamed or not), cats and endermen.
