B.O.W.

Bio-Organic Weapons (B.O.W.'s) are the main focus of Umbrella's weapon development sector 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.

A B.O.W.'s success is measured on its ability to cause panic, fear, and destruction; 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. Out of this research two projects specifically made considerable advancements and saw heavy development:

• Tyrant program
• Hunter program

The following B.O.W.'s are organized by their base organism's classification.
