Sickos

The "Sickos" are the zombie-like creatures seen in Planet Terror. They are mainly based from "Romero Zombies" as they are slow-moving and shambling flesh-eaters.

Origin
The zombies were created by biological chemical researcher, Abby. They spawned from a highly- deadly disease Abby created known as DC2, (code name: Project Terror). The infection is a bacteria that kills the host but keeps the organs working, also giving the host a hunger for flesh. It was meant to destablise high populations but Abby soon found a way to sell the infection to the military. However, he would only sell a part of his supply and keep the rest for himself.

Leads to the apocalypse
After Abby arrived at the military base with the army where his cargo handler brought the specimen sickos and drums of DC2, he discovered the speimens escaped. He executes his handler (but not before amputating his testicles). Before he dies, he yells to Lt. Muldoon in the Humvee that Abby has more drums than he says. A fight breaks out between the military and Abby's men in which Abby shoots open the drums, releasing the toxin into the air, infecting the soldiers and moving through Texas, contaminating them. From te gas and infectious bites from Sickos, the disease took out the world.

Spread of Infection
The infection first spread when the gas was released and floated over town. Those who were contaminated by it became zombies and bit others, infecting them. However, if the bitten part of the body is amputated before the bacteria takes over, the infection is gone. Contagious blood coming into bare skin doesn't seem to infect them.

Characteristics
The sickos are very disgusting. They are covered in pimple-like bumps all over their face and body, resulting from the DC2. They walk very slow and do not seem to run but are verys trong in their arms, teeth and biceps. They can pick a man up and throw him and rip a body part off in seconds. They are fast eaters, too.
