In Minecraft, zombies are one of many creatures that are known for attacking humans alongside Skeletons and Spiders. They have little to no intelligence but are still able to, at times, utilize swords and wear armor. Zombies in Minecraft usually attack their enemies in large hoards, overwhelming any 'non-infected' individuals they come into contact with. Though Zombies are unable to infect other humans they come in contact with, they are able to infect Horses and Villagers. A species similar to the zombie, though not an actual zombie, is the Husk.
Baby Zombie Edit
Baby Zombies are smaller versions of the standard Minecraft Zombie. They are faster, and tend to do slightly more damage than a normal zombie and are also known for mounting Chickens and using them to ride into battle, like a horse.
Zombie Villager Edit
Zombie Villagers are a subspecies of the standard Zombie that was created when a Zombie infects a Villager. They are the only species of zombie that can be cured of their infection via a Golden Apple and a Potion of Weakness. Baby Zombie Villagers can also be created when a young Villager is infected.
Giant Zombie Edit
Giant Zombies are a massive sub-species of the Minecraft zombie. They are much larger than the standard zombie, being relatively peaceful until provoked.
Zombie Horses Edit
Zombie Horses are a species of undead horses, probably infected by the Minecraft Zombies. Unlike other zombies in Minecraft, however, Zombie Horses are peaceful and do not attack humans. In fact, some Zombie Horses can be tamed by humans and used as mounts like normal non-infected horses.
Husks are zombies that inhabit desert habitats of the overworld. They have some differences to regular zombies, for example, they are slightly taller, they can survive in sunlight and can inflict poison damage.
