Zombie Pigman

Zombie Pigmen are a species of semi-sapient half-zombie half-pig humanoid creatures that exist in the Minecraft Universe.

History
Zombie pigmen can be found within the Minecraft Universe in a alternate dimention known as The Nether. Here, the Zombie Pigman species live among Ghasts, Magma Cubes, and Wither skeletons. The zombie pigmen are peaceful until you attack them. They are water and lava resistant. Somehow a pig in the overworld, if struck by lighting, can turn into a zombie pigman. This could be due to the lightning supercharging the pig into transforming into a zombie pigmen, similar to how when a Creeper is struck by lightning it is turned into a Charged Creeper.
