Mutated FOXDIE


The FOXDIE virus after undergoing mutation inside Solid Snake's body. The genetic identification program in the identifier enzymes that targeted only specific genes was destroyed by a sudden mutation, causing the virus to target anybody and everybody.

FOXDIE remained active in Solid Snake's body for a long time with help from nanomachines, though as a clone, Snake exhibits accelerated aging. This caused a sudden mutation in the FOXDIE virus, creating the mutated FOXDIE.
