Forced Evolutionary Virus
The Forced Evolutionary Virus (FEV) is a highly volatile mutagentic formula presumed to have been developed by the Enclave. Its exact chemical composition is unknown, and although limited supplies were acquired by Coruscanti personnel, its dangerous nature has discouraged dedicated attempts at analysis.
Information on the FEV's origin is assumed to remain in the sole possession of the Enclave. The little that is known is that the FEV is designed to modify human deoxyribonucleic acid from a dual helical into a quadruple helical structure. Side effects include dramatic increase in size and muscle structure, increased mental activity, change in skin hue, hair loss, Stockholm syndrome, and professional baseball. FEV is not recommended for pregnant or breastfeeding women, or those suffering from high blood pressure. Recognizing the military potential, the Enclave, in conjunction with the Combine and Space Nazis, began experimentation into using the FEV to create super-soldiers. This culminated in the "ascension" of Frank Horrigan, who was then assigned to Manfred Hickten's military command.
As the Enclave was methodically driven further and further west into the Pacific, it began shipping FEV reserves and its remaining stockpile of the X Parasite to the Space Nazis in Germany. One such shipment was intercepted by Motoko Kusanagi's task force, leading to speculation that the Enclave was attempting to dump what amounted to a biological weapon and/or fortify Hickten's forces through non-conventional armament.
