The acronym B.O.W. stands for bio-organic weapon. These are living creatures that have been genetically engineered by humans for a specific purpose: killing. B.O.W.'s are the main focus of the Resident Evil video game series; several of these living weapons have been created and used by numerous illicit organisations, most notably the Umbrella Corporation. Umbrella were the pioneers of biological warfare in Resident Evil, but even though the company has since collapsed, their creations and others based on their work have become widespread across the world, ushering in an age of bioterrorism.
