Las armas biorgánicas son formas de vida orgánicas que han sido transformadas en armas normalmente con una infección vírica. El virus está diseñado para transformar al huésped en una criatura preparada para enfrentarse a situaciones de combate sin llegar a matarlo. Las criaturas que escaparon durante la filtración del virus T en Raccoon City en 1998 son ejemplos típicos de armas biorgánicas.
Bio-Organic Weapon—An organic life form that has been turned into a weapon, usually by means of viral infection. The virus is designed not to kill the host outright, but to transform it into a creature that is suited for combat situations.
The creatures that ran amok during the leak of the T-Virus in Raccoon City in 1998 are typical of such B.O.W.s. One of the most effective B.O.W.s produced by the T-Virus was the Tyrant, which gave many Raccoon City survivors a run for their money. Its high intelligence and strength made it a focus for researchers.
Records of this are kept even with the BSAA. Below is one of those records.
The "T" in T-Virus stands for Tyrant: the ultimate human-based B.O.W.. Not only is a Tyrant incredibly strong, but it is also intelligent and capable of following orders. No other mutation may ever be capable of surpassing it.
