B.O.W.

Bio Organic Weapons (B.O.W.) are the main focus of the secret bio-weapons development department of the Umbrella Corporation and other organizations, and encompass all organisms specifically engineered as weapons. The advent of these bio-weapons was due to the discovery of the Progenitor Virus and its subsequent refinements which allowed Umbrella personnel to mutate otherwise harmless creatures into efficient weapons. This quickly became the focus of the company as a whole and led to a lucrative business on the black market. Although it was a costly endeavor, Umbrella's status as the No. 1 pharmaceutical company in the world provided it with ample funding.

A B.O.W.s success as a weapon is measured on its ability to cause panic, fear, and destruction with ample combat abilities; but above all, its ability to be controlled on the battlefield. This proved to be a difficult attribute to obtain and was the object of development within Umbrella for nearly two decades.

The following list of B.O.W.s is organized by their base organism's classification and contains all known B.O.W.s to be created by several organizations, including Umbrella, its opposing organization and terrorist groups.
