FOXDIE

FOXDIE is a engineered Virus created to take out specific people by identifying the person's DNA and their Nanomachines.

The virus was injected into an unaware Solid Snake shorlty before he departed for Shadow Moses to take out FOXHOUND. The virus was programmed to kill off The DARPA Chief: Donald Anderson, the President of ARMSTech: President Baker and the entire of the GENOME Army. Also, Naomi Hunter made an unknown edit to the virus so that at some random point it would also kill off Solid Snake, because he killed her closest relative, Gray Fox. However, because Solid Snake didn't have the dominant genes of Big Boss as everyone thought, Liquid Snake did, it killed Liquid instead of Solid.
