Zombified Piglin

Zombified piglins (previously known as Zombie Pigmen) are undead neutral mobs that mainly inhabit the Nether.

Spawning
Zombified piglins can spawn in nether wastes and crimson forests, nether portals, from pigs struck by lightning or from piglins in the Overworld or in The End. They have a 5% chance of spawning as baby zombified piglins. Zombified piglins and piglins will not spawn on top of nether wart block.

A baby zombified piglin has a 5% chance of spawning as a chicken jockey.

All zombified piglins spawn with a golden sword, which has a small chance of being enchanted in Normal or Hard modes, up 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), zombified piglins 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
Zombified piglins spawn in groups of 4 in the Nether at light level 11 and below, commonly in nether wastes, uncommonly in crimson forests and are sometimes 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, portal ticking can be used to increase the rate of zombified Piglin spawning by repeatedly lighting and breaking a nether portal

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

Pigs
A zombified piglin spawns when lightning strikes within 4 blocks of a pig. If the pig is a piglet, then it transforms into a baby zombified piglin.

Piglins
A piglin or piglin brute that enters the Overworld or The End transforms into a zombified piglin after 15 seconds. When baby piglins transform into zombies, they do not have weapons, unlike baby zombified piglins that naturally spawn, and when piglin brutes transform into zombies, they keep their axes.

A zombified piglin keeps any armor or weapons collected before being zombified.

Baby zombified piglins also have a 5% chance of becoming a chicken jockey.

Drops

 * 0–1 . The maximum amount is increased by 1 per level of Looting, for a maximum of 0-4 with Looting III.
 * 0–1 s. The maximum amount is increased by 1 per level of Looting, for a maximum of 0-4 with Looting III.
 * There is a 2.5% chance to drop a if killed by a player or tamed wolf. The chance is increased by 1% per level of Looting, for a maximum of 5.5% with Looting III.
 * There is an 8.5% chance to drop their if killed by a player or tamed wolf. The chance is increased by 1% per level of Looting, for a maximum of 11.5% with Looting III.
 * All items that a piglin have picked up, except gold ingots, after transforming into a zombified piglin are dropped upon death.
 * for adults or for babies if killed by a player or tamed wolf.

The golden swords that are dropped have between one and full durability.

If a zombified piglin 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
Zombified piglins 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, zombified piglins bang on wooden doors and may break them on Hard difficulty.

In Normal and Hard difficulties, up to 55% of zombified piglins 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%.

Zombified piglins may pick up a illager banner next to it as pillagers do.

Zombified piglins try to destroy any turtle eggs they see within 23 blocks away horizontally and 3 blocks away vertically (10 blocks horizontally and 2 blocks vertically on Bedrock Edition), not counting the block they are standing in. When a zombified piglin is first spawned, it always detects nearby turtle eggs after exactly 2 seconds, as long as there are two blocks of air above it. However, if the turtle egg is placed after the zombified piglin spawned, the zombified piglin takes some time to notice the turtle egg and try to break it.

Even though zombified piglins 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
Zombified piglins are not initially hostile, but all zombified piglins within a 67×21×67 to 111×21×111 area centered on the attacked zombified piglin become aggressive and converge on the attacker (another mob or player) if any individual is attacked, unless the zombified piglin attacked is killed in one hit. In addition, some zombified piglins 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.

Zombified piglins 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 zombified piglin causes it to alarm and anger all zombified piglins in a 40-block radius. Having constant line of sight with a hostile zombified piglin causes it to alarm neutral zombified piglins (within a 40-block radius) every 100 game ticks, or 5 seconds only if it is outside of its player follow range. A zombified piglin remains hostile indefinitely if it is within entity processing areas and has direct line of sight with the player. Breaking direct line of sight causes a hostile zombified piglin to return neutral if their forgiveness timer (of 20 seconds to 27 minutes) expires. The forgiveness timer does not advance for zombified piglins in unloaded chunks. Therefore, if the player enters a Nether portal and returns, any provoked zombified piglins in the area remain aggressive unless another player was nearby to keep the chunks loaded. Dying will cause zombified piglins to become neutral toward the player if the gamerule  is true. They pursue players even if they have the Invisibility effect.

Neutral zombified piglins do not prevent a player from sleeping.

Hostile zombified piglins 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.

When a zombified Piglin is angered the normal piglins do not get aggressive and vice versa.

Trivia

 * The pre-Texture Update zombie pigman texture file has "THX XAPHOBIA" written on the unused section as a credit by Notch to the skin's original creator.
 * Deaths of hostile zombified piglins always register as kills by the player they are targeting, regardless of whether that player ever touched that zombified piglin.
 * The old zombie pigman was the only mob to have a "baby" variant that its texture is significantly different than its adult counterpart, with baby zombie pigmen missing the head outer layer and showing their skull. It instead appears inside of its head, which is a bug. However, this is not the case in Legacy Console Edition, because the baby zombie pigmen head outer layer displays correctly.
 * This bug also happens with baby zombies and their variants, which is visible only via Resource Packs.
 * After the Nether Update, when the zombie pigmen became zombified piglins, they no longer have a different layer on their head and their texture is now the same like their adult counterpart.
 * The zombified piglin's angry sound is played twice the speed of the original sound file in the game.
 * Applying the Classic Texture Pack changes the Zombified Piglin's model and texture back to its original.
