A Bio Organic Weapon, or B.O.W. for short, is an Umbrella and Tricell term for a creature intentionally created or genetically modified using a type of mutagen.[1]

Bio Organic Weapons were a major focus of research for the Umbrella corporation. Several successful examples include the Tyrant series, Hunters and Lickers. Las Plagas is also considered a Bio Organic Weapon due to the mutations the parasite can cause within its host.

Due to the rising use of B.O.W.s the Global Pharmacuetical Consortium founded the Bioterrorism Security Assessment Alliance, an elite military unit trained to combat Bio Organic Weapons.
