The Pokémon World Zombies are undead beings that were once humans or Pokémon infected with a highly contagious virus that turns them into zombies. They are characterized by their pale, decaying skin, cloudy eyes, and erratic and aggressive behavior.

One of the unique aspects of the Pokémon World Zombies is that they are not limited to just humans, but can also infect and zombify Pokémon. Once a Pokémon is infected, they become aggressive and will attack any non-infected beings they come across.

The virus that causes the zombie outbreak is highly contagious and can be spread through bites, scratches, and even through the air in some cases. The incubation period for the virus can vary, with some cases taking only a few seconds to show symptoms, while others can take several minutes.

The Pokémon World Zombies are known for their remarkable speed, strength, and endurance. They can run at speeds of up to 20 miles per hour (32 kilometers per hour), making them a formidable opponent for anyone trying to escape.

Additionally, the Pokémon World Zombies have demonstrated the ability to break through barricades, doors, and even large reinforced metal doors by using large hordes to overwhelm their targets.

Despite efforts to find a cure, there is currently no known cure for the Pokémon World Zombie virus. Anyone infected is doomed to become a zombie and pose a threat to the surviving population.
