Rodriguez (Resident Evil: Undead)

Zombies are most Humans that have succumbed to the T-Virus, usually infected by being bitten by a virus carrier. The researchers of Umbrella Corporation called them "Zombies" in reference to a Haitian Voodoo practice where witch-doctors are said to reanimate the bodies of the deceased for use as slave labor. They were to be used as Bio Organic Weapons. They serve as the main enemies of ''Resident Evil: Undead. ''

Background
During his trials with the T-Virus, Dr. James Marcus began to consider the impact that Human testing would have on his research, eventually forcing people into being guinea pigs for his secret bio-weapons project, usually kidnapping families. The result of these trials was the very first Zombies. While some were killed as it managed to kill and infect a researcher, the Umbrella Security Service Bravo Team managed to capture and contain some for further study and began developing more creatures based on the Zombies such as Shriekers, Bloodshot, Ubvisto, Lickers and Regenerators.
