King Zombie

 King Zombie is a special mutation seen on certain zombies. They appear at after Nick finds the vehicle with the fuel for the plane and become regular among common hordes.

Biology
It seems these zombies are created when a certain type of radiation is applied on people with anti-zombification chips, making them mutate even worse than Gas Zombies. These zombies are tall, have only a pair of jeans and multiple boils around the body. The most important thing is the beehive that the wasps build around their heads and neck and thier ability to 'send' a swarm of wasps to nearby zombies to enrage them and attaking anything live near them.

They are far stronger and durable that common zombies but when killed, the upper body explode in a mix of an unknown green substance (that has the same properties as the vomit blood from Gas Zombies), blood and guts; damaging anything within its radius.
