Zombified Piglin

Zombie pigman or zombified piglins are undead neutral mobs that mainly inhabit the Nether. (Request to add article for the Old Zombie Pigman, for Legacy console editions)

Spawning
Zombie pigmen can spawn in the Nether, from nether portals, or from pigs struck by lightning. They have a 5% chance of spawning as baby zombie pigmen.

A baby zombie pigman has a 5% chance of spawning as a chicken jockey.

All zombie pigmen spawn with a golden sword, which has a small chance of being enchanted in Normal or Hard modes: from 0 to 25%. This chance varies depending on the regional difficulty as the sword's enchantment is from 5 to 23 levels.

On Halloween (October 31), zombie pigmen have a 22.5% chance of spawning with a pumpkin or a 2.5% chance of spawning with a jack o'lantern equipped as headgear.

Nether
Zombie pigmen spawn in groups of 4 in the Nether at light level 11 or lower.

They spawn commonly in nether wastes, uncommonly in crimson forests and one sometimes is found riding a strider in lava oceans.

Nether portals
When a nether portal block in the Overworld receives a block tick, there is a chance of $1/2000$ (0.05%) on Easy, $2/2000$ (0.1%) on Normal and $3/2000$ (0.15%) on Hard for it to spawn a mob.

$$, they appear inside one of the portal blocks on the bottom.

$$, they spawn one block to the east or south of the portal (depending on which direction the portal is facing) and neither slabs nor lighting prevents this.

If a zombie pigman spawned in this way does not leave the portal it spawns on, there is a possibility of teleporting to the Nether.

Pigs
A zombie pigman spawns when lightning strikes within 4 blocks of a pig. If the player is riding the pig when lightning hits it, a zombie pigman appears on top of the player.

Even if the pig is a baby, the zombie pigman still spawns as an adult.

Piglins
A piglin that enters the Overworld or end transforms into a zombified piglin after 15 seconds.

It also has a 5% chance of becoming a chicken jockey.

The golden swords that are dropped have one to full durability.

If a zombie pigman wearing a or  is killed using a tool enchanted with Looting, there is a chance equivalent to the level of Looting used to drop the pumpkin or jack o'lantern, up to a maximum of a 3% chance at Looting III.

Behavior
Zombie pigmen move at 2.2843m/s and are immune to fire and lava. When provoked, their speed increases to 3.3845m/s or faster for babies.

Like zombies, zombie pigmen bang on wooden doors and on Hard may break them.

In Normal and Hard difficulties, up to 55% of zombie pigmen pick up any armor pieces and swords better than their golden one, which they drop with the same chance as if killed with Looting I, 9.5%.

Zombie pigmen try to destroy any turtle eggs they see within 23 blocks away horizontally and 3 blocks away vertically, not counting the block they are standing in. When a zombie pigman is first spawned, it always detects nearby turtle eggs after exactly 2 seconds. However, if the turtle egg is placed after the zombie pigman spawned, it will take a amount of time before noticing the turtle egg and trying to break it.

Even though zombie pigmen are immune to magma blocks, they avoid walking over them. However, if they are spawned or pushed on to magma blocks, they would then path find normally on them.

Mob type
Undead, they are:
 * Damaged by the status effect Instant Health and healed by the status effect Instant Damage.
 * Unaffected by the status effects Regeneration and Poison.
 * Ignored by the wither and affected by Smite.

Hostility
Zombie pigmen are not initially hostile, but all zombie pigmen within a 67×21×67 to 111×21×111 area centered on the attacked zombie pigman become aggressive and converge on the attacker (another mob or player) if any individual is attacked, unless the zombie pigman attacked is killed in one hit. In addition, some zombie pigmen have the ability to spawn reinforcements when attacked (similar to zombies and which can rarely include actual zombies). This applies to any hit registered as coming from the player or other mobs, including deflected ghast fireballs, from sweep attacks, snowball and eggs, or a skeleton arrow. This does not include fireworks shot from crossbows, or dispenser-shot arrows.

Zombie pigmen remain hostile from 20 seconds to 27 minutes (limited by the Anger NBT tag type). Approaching within the player follow range (35 blocks +/- 5%) of an already hostile zombie pigman causes it to alarm and anger all zombie pigmen in a 40-block radius. Having constant line of sight with a hostile zombie pigman will cause it to alarm neutral zombie pigmen (within a 40-block radius) every 100 game ticks, or 5 seconds ONLY IF it is outside of its player follow range. A zombie pigman will remain hostile indefinitely if it is within entity processing areas and has direct line of sight with the player. Breaking direct line of sight will cause a hostile zombie pigmen to return neutral if their forgiveness timer (of 20 seconds to 27 minutes) is over. The forgiveness timer does not advance for zombie pigmen in unloaded chunks. Therefore, if the player enters a Nether portal and returns, any provoked zombie pigmen in the area remain aggressive unless another player was nearby to keep the chunks loaded. Dying does not cause zombie pigmen to become neutral toward the player. They pursue players even if they have the Invisibility effect.

Neutral zombie pigmen do not prevent a player from sleeping.

Hostile zombie pigman have slightly different path finding than when they are neutral. For example, they would fall off edges that would cause them fall damage in attempt to reach the attacker where most other mobs would otherwise not do.

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

Trivia

 * The pre-Texture Update zombie pigman skin file has "THX XAPHOBIA" written on the unused section as a credit by Notch to the skin's original creator.
 * Deaths of hostile zombie pigmen always register as kills by the player they are targeting, regardless of whether that player ever touched that pigman.
 * The zombie pigman is the only mob to have a "baby" variant that is texture is significantly different than its adult counterpart, with baby zombie pigmen missing the outer layer of their head and showing their skull. It instead appears inside of its head, which is a bug.
 * This is actually the same case with baby zombies and their variants, which is visible only via Texture Packs.
 * The zombie pigman's angry sound is played twice the speed of the original sound file in the game.
